Your videos were exceptionally well-made and helped me build my MK4 without any issues. I can’t believe you don’t have more likes you have earned a subscriber thank you
Thank you so much for your feedback!
Thank you for the assembly MK4 assembly video series. My 10yo son and I could not have assembled the 3D printer w/o the videos.❤. Being 3D printer newbies, We used the instructions to gather the parts before each step and your video to help with the assembly. The Prusa MK4 is working perfectly, thank you!
Awesome, glad the videos helped! Enjoy the printer!
Thank you so much for this guide! I had built an MK3S+ and a Mini+ previously, but for some reason I had a rough time following the official MK4 assembly manual. Your videos were invaluable in the whole process, and saved me from a few critical mistakes. Cannot thank you enough!
Thank you! We could not have assembled our MK4 without these videos. We only ran into one issue with the Yaxis calibration ...which we managed to fix by going back and adjusting the bearings.
Glad the videos helped!
this is way better than the official video guide. thanks for the great work.
You're welcome!
Thank you very much for that guide.
Thanks to your great but above all clear video series, I managed to put everything together correctly in one go. I turned on the printer and everything works perfectly. Thank you for all the time you put into the video series. As a thank you, a small contribution to the next series of great videos.
Thank you do much!
Glad you found the videos useful!
Thank you for these videos. They were a huge help in assembling my printer and getting up and running quickly. They were thorough, complete, and clear. Excellent job!
You're welcome!
Thank you for this guide!! New Prusa owner and new to 3D printing. This guide got me through along with the manual. My Prusa MK4 build is complete!
Well done!
thanks for doing this i would not have been able to complete without your help
You're welcome!
What a great series of videos. They really helped me putting my MK4 together. You have indeed made the video assembly manual Prusa should have provided. My printer worked the first time and I owe it to you. Thank you so much!
Glad you found it useful! Enjoy your printer!
Your videos are very well made, and are an excellent resource for building the MK4. I just built mine from kit this week, and your videos were invaluable for demonstrating some of the harder-to-see connection routes for the cables and belts. THANK YOU.
Thank you for your comment. Glad the videos helped!
Amazing! I'm new to the 3d printers, but watching your videos I feel I can tackle the job to build my 3d printer!
100% you can! Just follow the guide to the letter and you'll be up and running in no time!! No need to rush - take your time!
Let us know how you get on!
Very detailed build videos! I just built a Mk4 this week using only your videos as a guide. Especially like how you call out the size of the fasteners for each step.
Excellent series of videos. Very well produced with great attention to detail and wonderfully clear naration. I shall have these on my laptop beside me as I attempt my Mk3-Mk4 upgrade. Thank you so much.
Glad they are of help!!
Excellent series of videos, thanks. There is one very important step you didn't mention in this video around 1:20. You put the two wires on the heatbed with two M3x10 screws and locknuts, slightly loose for "adjustment space", but you never showed the final tightening of the two screws and locknuts which would most likely be VERY DANGEROUS! Perhaps you can edit the video to show the screws getting tightened.
Thanks for a fantastic video. I used this to build my mk4.
But…..
From firmware 5.0.1 things have changed. If you place the ‘Y’ axis bearings as you mentioned it will fail when you come to calibrate it. Prusa have acknowledged this but not updated the video.
To fix this you need to place the bearings on the ‘Y’ axis as follows.
Single bearing on the right needs to be placed centred as in your video. The black seals on the bearing line up with the metal bracket that holds it in place.
The 2 bearings on the left must be placed as follows or it will fail a calibration test if you are running firmware 5.0.1 or greater.
The bearing closest to the lcd needs to be placed centrally like the bearing you just fitted. The bearing towards the back need to be place with the back flush with the bracket holding it. When placing it this way you will see a lot of the bearing showing towards the middle.
Tighten the nuts but make sure the bearings run smoothly.
If you have already built this printer and down want to fit the bearings as mentioned but it has failed on a calibration. All you need to do is this:
Download the very first firmware for the printer. Run the calibration it will pass all the tests (the older firmware is forgiving) then flash the latest firmware. As long as you don’t run a calibration you can keep on updating the firmware. But once you do a calibration it will fail again and you will have install the old firmware to get it calibrated.
Also if you have fitted the mmu3 installing the old firmware won’t work so you will need to fit the bearings as I have mentioned above.
Great Job, I watched all these videos in the series. This feels like the Prusa MK4 assembly manual in video form. Prusa could have paid someone to make this and it would basically look exactly like yours!. Amazing job.
Thank you!
Extremely helpful videos! I will say do not do the tightening trick with the lock washer, the walls inside the part are to thin to keep it from spinning in the hole and getting stuck. Happened to me and it wasnt all the in yet
Thank you for the videos, made the assembly for the upgrade kit much better!
Amazing series! Works like a charm!
Thank you, great tutorial!
I'm extremely thankful for these videos. You are great! If I may add something, it would be very good to recommend at 10:00 to clear the holes of the y-carriage that you are going to screw the y-belt holders to. Mine were not properly made and I could not screw the holders in place. I could somewhat get them in position but then it was too late and I could not screw them tighter nor remove them any longer, so supported instructed me to break the holders to be able to remove the screws and clear the holes.
Anyway, I'm sad because I can't finish my build until replacements are sent, but still THANKS!
Ah, I didn't have this issue but thanks for sharing the tip!
Amazing series of videos. I was able to build my MK4 without any problems. Relying on just the online instructions would have taken me much longer.
Great! Glad the videos helped!
A new Prusa build series is on the way - check back soon!!……
This was an EXCELLENT video walkthrough guide\series. THANK YOU!
You're welcome!
Thank you so much for this series
You're welcome!
Great videos only part I got stuck on was the nextruder, need to fix the Z and Y axis
Bedankt
Thank you!
Somehow on the Y belt tensioner i managed to shear a screw when trying to get the nylon nut into the part 😂
THANK YOU, I AM VISIONED IMPAIRED, AND YOUR VIDEO TOOK ME THROUTH THE HOLE THING, I HAD TO WATCH OVER AND , AGAIN AND AGAIN. AND MANEGED TO GET IT ASSEMBLED , I WAS UPGRADING TO 3.9 , I DID HAVE TO USE SOME OF THE OLD PRINTER PARTS, AFTER ALL , I CAME TO A HALT AT THE CALIBATION SELF TEST .THE Y CALIBRATION FAILED , I HAVE DONE EVERYTHING I CAN, AND I AM STUCK ON THE Y CALIBRATION , HAVE NOT BEEN ABLE TO GO ANY FURTHER . ANY SUDJESTIONS, I CAN USE THE HELP
Apprently a lot of people in the coments are saying that the instructions were wrong about positioning the two bearings closer to the center and that it's causing Y check failures. See the comments on that section of their site. Did you have issues with that?
Mine is built exactly as shown in this video and I’ve had no issues at all so far [touch wood!]…..
The part about aligning the belt "length-ways" confused me so much. I had no idea what I was supposed to be aligning, and after reading tons of comments on the section of the official instructions, I'm even more confused because so many people had issues here, using "shims" to adjust, and even printing a modified version of the printed part attached to the Y motor.
I eventually decided the alignment was regarding the belt's position on the "y axis motor pulley", the cylinder with the teeth connected to the motor which pulls the belt... But I'm still confused because the picture on the site and the belt on your build in the video BOTH show the belt all the way to left, not centered... And that's what mine looks like as well. So that's correct?
The belt should be completely aligned from the front of the printer all the way to the back - so the motor pulley needs to move so that the belt is straight an don't installed slightly slanted.
I finally finished it last night. I centered the bearings I mentioned earlier and I don't really understand the belt alignment still, but praise God it all worked out perfectly and my first prints came out awesome. Thanks for your help and for your work on these videos!! Watching your series along with following the official guide and reading the comments on each step was the way to go!
hello is there some kind of starting filament included in this kit?
Yes, a small sample is included to test and get you started.
I have a question to your power supply. Is your plastic part, where switch and cable input is placed on also so wobbly?
If I just wiggle at the cable a bit, it falls out. I can push as hard as I want, but it wont insert fully.
You mean the plastic part that covers the connections? If so, no mine seems to fit reasonably tight.
I have solved it. The power cable was not fully insertet in the power supply. I had to push really rellay hard (I thought I would break it) to get it in like it is suppoet to be. @@iftibashir
And thanks for your Video Tutorial. I assembled my MK4 just by your Videos 😊
@@julian_loewe1977 You’re welcome! Glad it’s sorted! Enjoy!!
My tensioner screw will not reach the locknut, no matter what I tried.
