- This wasn't the video I planned on making for my newly purchased Prusa MK4 3D Printer. Unfortunately, I am continuing to run into lots of issues.
The good news is the Prusa Support team rocks & wants me to send it back so they can review it & see what's wrong with it - potentially preventing future issues.

UPDATE - wow you all are some wild 3D Detectives! Yeah if you go to the 35:00 mark in my live unboxing of the MK4 it’s my first test print - fan is not working - does look like the wiring is wrong on the unit which might explain the clogs & extrusion issues I was seeing
ORIGINAL Comment - By the way... this all took place within the first 24 hours of me using the machine - it's with DHL and on its way back to Prusa Support 🤘
Wait… you didn’t see the fan wasn’t working? 😂
Glad to hear that. Have ordered a few and this video sure got my attention lol
how can the problem be fixed? I have the same problem
Nice detailed vid.
No offense but how the hack can someone with 3D printing expirence not see that the fans are not turning on when they should be? Thats like basic troubleshooting checking if there is a cooling / temperature issue...
I think the wires for the hotend cooling fan and the part cooling fan are switched as I noticed the part cooling fan turning on during the first layer whilst the hotend cooling fan was not, usually the part cooling fan is turned off during the first layer and the hotend cooling fan is turned on when the hotend temp is above 50c .That could have been a be a big reason you might be experiencing jams from a phenomenom known as heat creep where the heatsink starts to heat up and the plastic becomes sticky and melty too early and that usually causes jams.
I just watched his unboxing video and I think you're 100% right. The part cooling fan was on during the first layer while the hotend fan was off. I then see the hotend fan kick on after the first 2-3 layers. So they're definitely reversed.
Nice catch. I noticed that the nozzle fan wasn't running but I didn't realize that the other one was when it shouldn't have been. That's probably most of his problem.
Y’all are 3D detectives! Will pass the notes onto the support team as well for them to check
What a catch! That would make a lot of sense, surprising for sure that it slipped though their QA.
This also caught my eye during the print you showed in the video. The hotend fan is off during the first layer, that's why the nozzle is clogging. On the other layers is on, thus no clogging. The stand has a huge first layer, that's why it consistently fails and the other prints are ok. The dragons seem to be on the edge
Do you always put your fingers on the build plate like that? I know we are not all created equal, but for me this is enough to create adhesion issues...
Sorry to hear you are having such issues. I had similar clogging issues on my pre-order Mini, which were fortunately a fairly straightforward fix. I'm not buying a MK4 but I am on the pre-order list for an XL. Hoping for a smoother launch considering the price of that one. I do have faith in Prusa's support to get things right if it does have teething issues.
Good news is my replacement Mk4 is printing amazing!! Loving the machine minus the extremely slow wifi transfer speed for files
Prusa support is the reason I bought my MK2s. Still have this printer. I'm certain that Prusa will get this figured out.
Thanks man! Yeah I’m confident it will get sorted
but how long / many years will it takes for Prusa to fit??
Prusa needs to come out with mk5 yeasterday to save themselves
I had had enough problems with my factory assembled MK3s+. I went through hell for 6 months with customer support. Never could get a decent print with my Prusa. A couple of weeks ago, I gave up and disassembled that printer down to the last screw and gave it to the city. Never again. Did Prusa care that I wasn't being helped? Evidently not. I'm still miffed.
To display print quality, it is critical to shine light across the side so shadows from uneven layers can be seen. Just bouncing the light off the print at 45 degrees hides all the imperfections and doesn't show me anything. It would be great if the actual surface roughness could be characterized for different printers numerically. I just don't need another printer that can't produce a flat side surface.
Yeah my lighting is all out of whack at the moment
I have a mk3S+. And I love it. It is dialed in and prints perfect. I’ll stick with it. My first layer is perfect and I am glad I decided to wait in getting the mk4.
I'm not super familiar with these but it looks like your nozzle heat sink fan wasn't running most of the time. I assume it's supposed to be running anytime The nozzle is hot right?
Yeah some mention it looks like the cables might have been installed wrong / backwards
Hope you get it working perfectly soon! I'm looking to get one
I like this. It was an honest review that made me question my trust in Prusa, and then a read of the comments from later reaffirmed my trust.
I would like it if my next printer is a Prusa, but for the size and detail I need I may be able to get away with something cheaper.
Hi uncle Jessy, thanks for putting out this video. I was wondering what they told you to do for the nozzle digging in during self leveling in the first corner and if it worked for you? Thanks !
Umm is it a framerate timing thing or is the hotend fan not spinning when it was "clogging"?
I was about to say. Cuz in some shots it’s moving in other shots it’s not
hmmm def looks like it wasnt going. I wonder if I just have a bum fan which was causing a lot of the issues
I agree the hot-end cooling fan is causing his clogging issue.
@@UncleJessy It seems to be spinning fine with the little dragon things that you got printed. My guess is bad pre-sliced file(I don't use these) or bad fan configuration in your slicer or maybe bad wiring since you had so many other mechanical issues. I don't know why manufacturers even make the extruder fans controllable. They should run any time the heater is active, there are no positives to letting the user control it.
My experience with e3d hotends in the past. If the heatsink heats up due to lack of cooling, it will cause the plastic to melt early and cause it clogg.
Looked like a fair bit user error to me for someone not used to printing on a Prusa or building Prusa's.
Anybody who builds printers would carry out checks such as test to 50°C on each heater to check rise and corresponding fan function.
Belt Tensioning is a skill that is learnt.
Prusa will resolve quickly as usual I'm sure to provide belt & braces.
You'd think that, wouldn't you. Maybe we should ask *the Prusa technicians who built this unit* why they didn't carry out those checks, as they are definitely guys who *build printers* ...
@@extectic Indeed, but I also think that buying a 3D printer should never come with the belief that you can just open a box and print. These are still mechanical devices with no real mind of their own, no functional safety and the "on demand" nature of the first world is expecting to much from this industry at hobby level. Managing expectations is important for the first generations of new products.
Is that fan that's not turning at 9:00 for the extruder? If so, I think that explains your jam.
I agree. Likely a heat creep due to fan failure. I think on the new board extruder fan disable is a thing so there might be bug with the slicer/gcode, since he was able to print another gcode just fine, but consistently failed the controller stand.
Yeah I think that is more than likely causing the jamming unless the fans are set to off for the first layer 🤷♂️
@@VuLamDang It is running when the dragons are being printed though. Both first layer failures with the black filament, it's not turning though.
That makes me think what's actually going on is his cooling fan and extruder fans are swapped. Since the dragons have less surface area, they'd get through that first layer faster but still with problems(as seen), after the first layer it turns on and finishes it fine. I don't know if Prusa extruder fans are hardwired or software controlled but I don't think extruder fans should be software controlled at all.
@@tmilker by being software controlled, it can be set to only turn on when hot which I think most people would prefer compared to having it go full speed unnecessarily when the nozzle is cold
Good, informative vids…subbed!
The clickbait is so strong with you
Honestly your experience with support is probably reason enough for me. My experience with another printer company felt like I was on my own. It's cool they are taking it back and replacing it!
When I bought my Mini I was having trouble getting it to print at first, spoke to customer service and they sent me out a free new complete hot end assembly.
While I do love my printers from prusa...i've had issues with some other things from them...but their support is top notch and has no equivilant. You can tell when a companies priority is customer satisfaction...and for them it really is.
I had to contact support for both of my prusa printers.
The first time was for the kit of the SL1 (resinprinter): when Ive tried to screw in the little rubber feet the screw got stuck somehow. The thread was damaged. Dont know if it was the thread of the bottom plate or the screw, but I couldnt get it out anymore easily. So both threads where damaged.
Support send me over replacementparts whcih arrived only a couple of days/ within a week.
The second time was a problem with the mini (also self assembled).
The selftest failed all the time at start up and blew a fuse out. Replaced mentioned parts on my own with help from the forum guys (mentioned thermistor).
But still the fuse blew out.
So Ive contacted the support, send them over pictures.
I started looking at the online help and ended up on the picture for the fuses and noticed on my own (before the support guy answered) that the fuses where switched with each other.
On the assembly kit these are pre-installed.
In both cases the support was friendly, super helpful and fast in answering.
Amazing!
I would never exchange that with a chinasium 4th reich company support!
No matter how cheap they are.
MK is pronounced Mark 🔥
Never use pre sliced gcode. Just slice it yourself. Good video! Loved it.
I would have however Prusa doesn’t share the file to slice. They only offer the presliced gcode files to print for the belt tension tester
Then don’t print it. NEVER print gcode you didn’t slice yourself, no compromise
The fact that printables even allows gcode to be uploaded is effectively a bug. You're lucky it was just a build plate.
Nonsense, just check the gcode before with a gcode viewer.
@@UncleJessy Then don't print it.
Prusa support is AMAZING! I hope they get things worked out before I upgrade my MK3S+
At around 09:00 it's printing a first layer, but the hotend cooling fan isn't running, and I think the part cooling is?...
I'd say that larger first layers are failing / clogging because of a faulty wiring or setting of the hotend / part cooling fans?
Yeah, this is the Prusa assembly technicians failing right here. I suppose you can't expect perfection, but belts wildly incorrectly tightened from the factory and a hotend fan that's not spinning, that's just pretty darn awful quality control for a $1000 unit.
Ha, ive ordered the mini kit.
Was fun to assemble but it only spew an error out during the start up self test.
Ive ordered new thermistors and nozzle heating element (error said there is a problem with that) and it still spew out the same error.
Also a fuse was always blowing out (which I had to buy as well). Blew through 5 fuses.
Contacted the support, send over pictures.
And then I noticed something:
While I was looking at the online help about the fuses:
The picture was different!
The fuses where exchanged with each other!
Switched them to the same like in the picture and it worked!
The fuses where pre-installed, so it wasnt an error of mine and it wasnt mentioned in the building manual of course. Obviously, since it wasnt mentioned, I havent taken a look at the placement of the fuses.
But then it worked and still does!
But that was a rocky start ^^
the video is so good!!!! How does QIDI Max 3 perform? really want to know
YIKES! Such a bummer to see so many issues, but that's great to hear that Prusa is taking it seriously and reviewing the machine!
Yeah always great to see a company like Prusa being proactive about their issues (or dumb users who print on wood haha)
@@UncleJessy Or dumb users who use g-code for the wrong printer wondering why the sheet is damaged and the extruder is clicking because of a self-forced clog. Seriously the only thing wrong with this unit is the hotend cooling not running
So many? There were literally 2 issues, one of which was completely user error. The fans are in the wrong connectors on the board. 5 second fix.
I have been having only bad experiences with Prusa lately. I bought the conversion kit from MK3 to MK4, when they started to sell it, I asked for the parts list and they told me they didn't have any. How can you start selling something without a part list. Some other bad customer service experiences as well. Prusa needs to improve
Also wanted to point out the radiator fan is not working 7:12 but seems you already figured it out. Sometimes it spins and other times not in the video.
Interesting you had all those issues… I have two mk3s/+ kits and haven’t had any issues other than the funny noise. The 2nd printer has a vibration when the extruder lowers at the start of a print but after it started it is fine. I am on an IKEA desk.That amplifies the sound. I need to loosen the axis and Check for racking. I hope the new one is better for you.. I hope they send that then you send yours back in the same box. I am sure you’ll find the machines to be a rock solid work horse that you’ll want to get more of because they just work.
Yeah I’m excited to get a replacement on mine fixed and back to me. Really wanting to use it for some high quality print sales
Never heard back from Mingda, so Prusa demonstrates customer support as it should be.
Just bought an mk4 in kit, took me 13 hours to build it, made a benchy incredibly perfect on very first try. Astonishing printer.
That's my experience as well. One of the reasons for going with Prusa is their support. People are having a worse time of it with Bambu support, or so I heard.
I bought my first machine way back in 2014, You will run into many of these issues everyday. Welcome :)
So my original mk3 gave me a ton of problems, like you had. Lots of first layer and shifting issues. Support was great but after 2 weeks of troubleshooting, I was ready to return it and give up. Jo himself somehow caught wind of it and support shipped me a replacement unit which has been working near flawless for the past 4 years. With all that, I hope your replacement is just as good and will work for years to come.
A perfect first layer every time, 60% of the time.😎
The hotend cooling fan is off on those jamming first layers. Not surprising it jammed.
The USB drive that came with my Mini+ kit a year ago quit working in about a month. From what I've read this is common with the thumb drives Prusa supplies.
yeah i dont use either of the usb drives on my two mini's either. they are trash
Last I looked, the Mini (I bought after announcement), still lists power failure recovery...I don't know if they ever added it.
I was considering getting the Mk4 - of the printers you have, which do you recommend for consistent "just works" quality output that you'd be happy to sell products from?
With anything massed produced, you are going to have a percentage of issues.
I would be absolutely confident in recommending any of the Prusa printers.
Even in the unlikely event you experience an issue, there is awesome 24/7 live support that will help you sort it out and send replacement parts if necessary.
X1C, AnkerMake M5 & the Neptune 3 Pro & my main Etsy machines these days. Surprisingly the AnkerMake m5 & the N3Pro give me the least amount of print issues. X1c is awesome but will randomly have its issues. But prints stupidly fast
@Russell Phelan the Bambu offerings also lack the ability to replace a lot of the components and their support is...let's just call it 'lack lustre'.
It and the X1C are essentially disposable printers.
Wow, that would be disappointing to have those issues with a brand new machine. I had similar issues with a Creality CR 10 Smart (not the pro) printer and it would never properly level for me. It didn’t have any manual adjustments so I had to rely on the auto-level feature, which never got it level. It printed just fine on the right half of the build plate, but it dug in on the left side to the point that it ruined the build plate. I am seriously looking at this printer as my next purchase, but I’m going to wait to see if there are other people with similar issues before I shell out that much money.
Your receipt says 3 April and you got your printer already. Mine is 30 March. Where is my printer?
The extruder fan does not work when printing. Maybe wrongly interchanged cables in the LoveBoard with the print fan.
You made me a little happier that I chose x2 prusa MK3s over one prusa MK4 (spent about the same for two 2nd hand mk3s). Better to wait and work with what you know :P
i have on one order 6-7 weeks give em time to fix some things the first order of my solvo plus is a problem 2nd one is fine
I noted that the print of the controller stand failed at the same location three times. It was half way through the first layer. If the prints of different parts worked before and after the failed print, I would blame the gcode, or slicer.
From @9:00 you can see that the hotend fan is not spinning when printing. I think that is the cause why the nozzle is clogged.
Your hotend fan was not working in all cases you showed the clog.
This is a great unbiased review. Thx Unc
Not a review but for sure my experience so far with it. Positive it will get sorted
@@UncleJessy yeah, looks like they may have rushed the release a little for some reason.
The X-axis motor shaft has to be orientated correctly. The screw needs to be directly above the flattened surface. Concerning the sound. A hint of oil grease is wanted by the bearings ;-)
Thanks for keeping it real! Hope the next works like it should, but Love my sovol sv06 so much more now. Can get 4 of them for the price of that mk4.
Thank you for the honest review, i also think that prusa is overpriced
good with constructive feedback. thanks :-) waiting for mine to be sent.
Prusa states that an extra thermistor is installed in the heatbreak to prevent clogging caused by heat creeps. So, I'm wondering why this didn't prevent your printer from printing when it detected a higher temperature in the heatbreak due to the malfunctioning fan. Is it possible that this feature has not yet been implemented in the firmware (like input shaping)...?
That's what I'm thinking, but you still can read it in the settings. Hopefully they'll implement it soon
Hey I was wondering when are you reviewing the mars 4
Soon 😬🤘
I just hope Anycubic will be as helpful to me when I get my Kobra Max in the next few weeks. I just need to finish clearing up my Garage first.
Make some space for that monster!
Don't expect Anycubic to respond at all, their CS is almost as terrible like the one of Creality.
Hope you like facebook anycubic groups full of miserable people who say "search the group" or mock and insult you instead of actual customer support lol...
When is an in depth phecda video coming?
Is that a spool of Cookiecad Unicorn? Love their pastel colors.
Cookiecad pla has quickly become some of my favorite
I got my MK4 Friday, wasn't due until Monday! Also they said it would ship between the 12 and 15th. It shipped the 12th and I had it, and printing by 15th. It has worked flawlessly. I will stay away from cardboard/wood, as I have all three kinds of their build plates, but am interested in possibly printing some tee shirts some time.
Something can always go wrong, a company fixing it is really great. This is why I keep buying at Prusa..
The MK4 has a belt tension screw on the x-axis. When I got my MK4 printer this screw was not used by the factory build at all - resulting in inconsistent x-axis belt tension. I noticed it right away as I go over anything build by a "factory". It's one of the most accurate printers I have used... when properly tuned. Build in local network printing is great too.
Oh man I didn’t even get to checkout the network printing
as I don't ever own myself any prusa, but yes, they are well known for their quality, but, the add doesn't says like millions (joking of course but at least hundreds) of our pre testing units?
It's a bummer your machine isn't running right now, but Prusa support taking it back to make it right is fantastic... I like your attitude about the whole thing... It seems many people would explode and be upset... Stuff like this happens sometimes, but your response is refreshing and professional. I watch and depend on many of you guys about the 3D printers and I drop off the dudes that go off the deep end about some of their reviews. My new subscription is your thanks!
Well I don’t think I’ll be rushing to buy one just yet then 😮
Hello ! Did you consider Prusaslicer (i'm using the last alpha) the problem about budlge / layer shift / inconsistency layers for your crystals ? I got similar weird results too and i'm working with a Neptune 3 plus.
Hmm I didn’t. I’m using the official release & not and alpha if I remember right that has the mk4 profiles
@@UncleJessy Also the Arachnee mode gives me weird line from time to time because it increase the flow for on layer. And I don't know why for now. Check your flow to see if you have any issue on your printing to see if it's matching or na
I am currently building mine and am runnning into a ton of error codes
at the 9 min mark I notice that the hotend fan isn't spinning, that would explain the clog...
Oh yeah. I was getting rough surfaces (with my MK3) on my prints and found that it was because prusa slicer had defaulted to the MK4 profile on me.
This is why I typically do the kits. Save some money and make sure it’s built perfectly. Nobody will care about the build quality more than you. Unless you happen to be a total contradiction and are “maker” that doesn’t like to build things and pay attention to details. Most ppl that 3d print are in to electronics anyway.
PS. If you had built this it would have caught the fan not spinning in the initial self test.
did you notice in the "support wants it" section your heatsink fan is not spinning
My gcode, my prints =) But seriously great video! Looking forward to building the kit soooo much!
Oh no! It can’t be. Prusa is perfect. I tried to buy a MK4 and had to get the wonderful women at my bank to get my money back after Prusa took my money and canceled my order. My only contact with Prusa was with someone who didn’t have enough English to communicate.
Getting another Bambu? I’d never buy a Prusa bed slinger when bambu is this good and just starting.
Interesting. The similar was like with MK3 issues were fixing for whole 2 years, first mechanical, cooling, and at last firmware.
I think the prusament PETG filament is poor to be honest. I can’t get any good results from that.
I love all my Prusas, but they are not appliances or tools - they are tinkerer's toys. For me, and many others, Prusas will be be the fun weekender, and Bambus nowadays do the work in 'set and forget' mode.
I’ll take it!
Great video and super honest review absolutely love it
O damn i love my voron
sometimes issue happen, the difference is make from the assistance and after sell service, always on the top with prusa
Yeah they have been great to work with on this
I really want to upgrade my MK3S+ (which started as an MK3) to a MK4, but I'm kind of glad I don't have the money yet.
I'd wait for a while to see if it improves, don't brake a good printer.
@@ianmcleod8898 That's why I'm kind of glad. I also have the mmu2, and that's even more money I don't have!
After the antics you pulled with the MK4 in your first video I'm surprised that Prusa was so nice. You used the printer as it was not intended and then complained it didn't work right afterward. Most of us thrive to have this printer and then you just abuse the one you received. Thankfully it's the first and last videos of yours I'll ever watch.
Very fair video. Well done. Thank you for sharing.
Ordered the MK4 kit the other day, super on the fence with whether or not it’ll be worth it. My MK3S has been a total workhorse with no failures aside from my own since I’ve owned it. But with all these very obvious issues shared by yourself and others it tells me they didn’t actually test this as much as they are claiming.
I don't own prusas but it seems like some of his problems are because the hotend fans are swapped. Since the heatsink fan is off during the first layer, it clogs. Seems like an assembly problem
If you read the other comments it looks like it was put together wrong by Prusa themselves with switching the fan wiring. Luckily for you with a kit you’d only have yourself to blame 😉. In all seriousness I’m not that concerned as Uncle Jesse said, their support is the best in the business and have helped me numerous times with my mk3s and mini. Looking forward to receiving my mk4 kit
The only issue was a reversed wire for the hotend...that's a rain drop in the ocean for issues, compared to someone like bambu lab.
@@LilApe "the only issue" was the fans were assembled wrong from factory...and the USB drive died...and the bed calibration dented the bed ... and connector on the bottom that scraped the surface the printer is on ... and the nozzle was clogging ....
This is not what you expect for a company charging $1,300+ for a printer.
@@cjjuszczak Dude...the nozzle was clogging because of heatcreep...because the hotend fan was wired wrong. That was the only legitimate fuck up prusas part. The nozzle denting the bed is what happen when you run a MK3 file on an MK4..the gcode is reading for a pinda probe for leveling, when there is none on the MK4. The USB drive died? are you seriously acting like that a prusa problem lmao? Prusa doesn't make USB drives, just grab another. Look at all the faulty SD cards that ship with 3d printers. You're REALLLLLY reaching here dude.
They took his printer back, no questions asked. Look at companies like bambu lab that just tell you to read a wiki and avoid all possibility of accepting a refund/replacement.
I'm kinda curious about that fan too. The MK3 had tachometers on both the hotend fan and the part cooling fan, and if one of them stopped working the printer would error out. Did they remove that feature from the MK4?
The fan is spinning, it's just the wrong one. If the plugs are switched the printer wants the fan to spin and it does spin, it's just the wrong fan. Maybe they could detect it if the RPM ranges are different
So, basically, belts wasn't tightened and hotend fan wasn't spinning. Why return it?
@Uncle Jessy: Something bothered me on the beginning of your video, when we can see your printer printing the first layer: The cooling fan (blowing on the hotend, not the one blowing on the layer) should be turning! This is odd, this fan is supposed to start when the temperature of the nozzle exceeds 50°C... So I think that's the reason of your clogs (cause of heat-creap).
Maybe the fan is not activated for the first layer because you tried to open a MK3 GCODE on Prusa Slicer that replaced some parameters?
Long live Bambu Lab
Love your videos Jessy.😉
Thanks for sharing your honest views, hope Prusa irons out all these initial QC issues and your replacement printer comes pronto!
Yeah I have no doubt
Bambu Labs FTW!
That’s a total bummer!! My MK3+ has been a flawless workhorse for years. I hope your replacement printer gives you a better experience :)
Same with mine, it's a workhorse. Mine is 6 yrs old now.
That’s what I’m hoping for + upgradability + the support
The resonance these machines produce is really loud from what I noticed. I have a modified X5SA-400 where I fine tuned the resonance of my motors/drivers, so you would think Prusa would offer some tuning options for this as well. Why is your hotend fan not on? I only noticed it when you printed the little dragons
The MK 4 has the same issue as the other series where it makes a visible band about 5mm from the bottom on the benchy. You can see it in the video.
Every 3D printer shows that issue. Look at Vorons, Bambu Labs...
@@coltenmeredith8899 Why does it happen?
@soacker25 It's the leadscrew not being straight. Basically, it moves the whole bed/gantry (depending on the printer) in the way the leadscrew is bent, thus moving the hotend, which makes these marks. The only way to fix this is to use an oldham coupler or a flexible coupler on the leadscrew, OR you could go nuclear and swap from leadscrews to belts (basically, using belts to move the Z axis, like the Voron 2.4)
Lol the republicunts at bamboolab in full panic mode.
started watching you on Tiktok finally bought my first printer, thanks for the great content
This issue with the indent at the probing point I also see on my Neptune 3. I guess that is simply a downside of nozzle probing unfortunately.
Yeah - I mean, the nozzle literally has to ram into the plate to find the plate. The Pinda and Z-leveling may not be perfect but at least it never touches down. Does require knowledge and tuning the Z-level fairly frequently though.
@@extectic Tuning the z-offset fairly frequently? Are you constantly moving your printer? I've set it once and saved it on the settings and never changed it in over 2 years. Only changing plates and profiles, that's all.
This reminds me of when Joel was having issues with his assembled MK3 a few years ago. Hopefully it was heat creep as some users are pointing out; I remember raging at the office Raise3D Pro because that thing will heat creep if you look at it wrong.
I have a bondtech extruder swap for my raise n2 that I’ve been meaning to do for almost 2 years no 🤦♂️🤦♂️
@@UncleJessy You don't wanna know how old some of my bucket list entries are. XD
Yeah, first layer looks ok, but I can get the first layer glass smooth on my MK3, your first layer looks like it's got a few lines in it.
Yeah I think they were calling out some of the edges and corner that weren’t as smooth
@@UncleJessy I was referring the first layer on display at 3':30" (lefthand side of the screen - obviously !), you can see those vertical ridges throughout the first layer, I can't remember what they indicate (either under or over extrusion I think), but you can definitely do a better job on the MK3 . . . anyhow, be interesting to see how you get on with your return Mk4 . . . by the way, my factory build MK3 also had a few build quality issues when new, bolts screwed in at weird angles, a couple of busted parts . . and so on.
now with the cheaper creality bamboo lab clone you need to ask why mk4
clogging is caused by your hot end cooling fan not running!!
Why are Prusa still shipping those awful USB sticks. It's the same one they've been shipping with the Mini since it launched and every one of them has failed (I have 7 minis).
Maybe wait 6 months or so before buying a MK4. Give them time to fix issues.
