Thanks! The CPAP fan is the champion here though 😅

Thanks! I find this mildly annoying as well, but afaik are no rules relating to categories or grouping when it comes to printing speed boats. It's just a Slicer rule preset and it has to come out "dimensionally accurate within reason", which basically means it needs to have the shape of a Benchy :/

You can find details in the description (which annoyingly is hard to get to on shorts), but the most interesting part is the link to the official project that I use portions of and have done some modifications to: www.orbiterprojects.com/beltender-linear-rail-upgrade-for-ender-printers/ As for the tramming, I have been running this setup for over a year now and the gantry has been completely straight the entire time after I got tings squared up, correct belt tension and making sure the pulleys are all running good etc.

I use a slightly modified LDO BeltEnder for Linear Rails and not the V-Slot wheels. The one you linked is for the original gantry setup. I have not tried any of these conversions, so I sadly have no recommendations here. It looks pretty nice though. At least if it's printed with a good quality and heat resistant filament. It might add some resonances because it's mounted on top of the frame where things are most wobbly, but probably not an issue if not going super fast speeds :) LDO BeltEnder documentation: www.orbiterprojects.com/beltender-linear-rail-upgrade-for-ender-printers/

oh!! i understand, thankyou so much your recomendations!, i will check 😁❤

​@@carloshiramgomezbarajas173 No problem! There's quite a few Z-axis belt mods out there on Thingiverse and Printables. So plenty of things to look into. You can even get some fairly cheap Aluminum full conversion kits from Aliexpress.

Thanks! It's a slightly modified BeltEnder setup. This was the first modification I came across that I could do with just using parts from storage and very few printed parts. Works really well! :) Just made a short video so you can see it in action: czcams.com/users/shortssbl9ZH7pYrs

@@andersevenrud Thanks a lot! i will go to watch rn :D!❤

My original plan was actually to build a Voron with most of the parts used. Then got kinda sidetracked with tuning and thought it would be fun to see what happened if I slapped it onto the Ender. I don't think I'll try this profile on anything else than benchmarks because there's no way my 0.4 nozzle could keep up with that over large areas. And things gets a little bit too smoothed out around corners, so tight tolerances would be a problem. But in this process found a pretty sweet spot that spits out a benchy in ~15mins that works for most prints that I do.

Nice :) What brand of 5015s did you get ? That was my previous setup and it could not cool things down properly on a ~20min profile. The bow overhang inclination always came out deformed because of curling layers up even when going as low in temps as I possibly could. I tried so many, but never got results that I was super happy with. I did do some resonance testing before and after installing the braces, but there was not really much change. Probably within margin of error. Though, I did not test things far up on the Z-axis. That's probably where it helps out the most.

@@andersevenrud I have tried alot of fans. Right now im using gds time, I think they are 6000rpm and seems to push a decent amount of air.

​ @abengtz Aha. I gotta check those out.

It's a 7040 CPAP setup on a Hero Me with this duct: www.printables.com/model/631801-hero-me-gen7-cpap-dual-ducts

I'm actually running without stealthchop. 64 microsteps and 1.60A run current.

@@andersevenrud that is a damn quiet machine or great noise canceling mic

​@@raiden9250 I recorded this on a Galaxy S21+ without any filters, but the noise from the CPAP cooling pretty much drowns out any sound from the steppers and the motion system. However, it's actually fairly quiet in person when not running the fans at full blast. The most annoying noise actually comes from the pin resonance inside the BLTouch rattling around when going past ~100mm/s (audible in the homing stage).

SCV is the "square corner velocity" in Klipper. It's how fast you want travel moves to be around 90 degree (or more) corners. It's kind of like "Jerk" in Marlin FW.

You can run a stock machine pretty fast by just increasing the acceleration in FW considerably and go all out on slicer settings. The results gets really good if you tune Pressure (linear) Advance and do Resonance Compensation. But the main bottleneck is the hotend. You won't get much more than 10mm3/s volumetric speed before extrusion issues, jamming and all kind of other bad stuff occurs, especially on larger prints with long straight walls. Higher temps can increase it a little bit, but then stringing and cooling issues really starts impacting the quality. So if you wanna go more than just a bit faster I would recommend looking into a V6 style hotend kit.

@@andersevenrud thanks a lot for the tips.

if it works, it works.

It's currently sitting on a metal cabinet with extremely skinny legs on an uneven floor, so it's not really stable... but works just fine :) All the noise is things inside the cabinet moving around, heh. Sounds like a washing machine running from the next room.

It's indeed the CPAP cooling that makes this possible. It's running at 100% here, which is a bit too noisy for my taste. As for modifications the first thing I did was to convert to linear rails, belted Z-axis and installed higher torque stepper motors. From description: 25000mm/s² Acceleration, 50mm/s SCV, 400mm/s (100mm/s first layer) print & travel moves. LDO Orbiter v2, Phaetus Rapido UHF w/Bondtech CHT 0.4mm V6 nozzle and 7040 CPAP cooling on a HMG7 toolhead. Using eSun PLA+ filament at 220C. Official 3DBenchy STL sliced in PrusaSlicer 2.8, oriented 45 degrees, and using Speed Benchy rules

@@andersevenrud Thank you for your reply! It is very powerfull this CPAP cooling indeed, impressive to say the least. It is the first time I am seeing this promising cooling technology. Yes noise is naturally the trade off one must make in this situation, but the short print time definitely makes up for it. The other upgrades are also really nice, all of which I would like to do my self - especially linear rails and belt driven z axis. The only upgrades I have made to my 3 v2 is all Noctua fans, BL touch and Micro Swiss NG direct drive extruder. Are you running Klipper on your machine?

​@@RandomUlrik I'm pretty sure that the design of the fan ducts I'm using is not optimal. I've seen other machines run at around 50% with the same effect and it does not sound much different from a 5015 at full blast. Linear rails and solid bed mounts is a very nice upgrade. It pretty much eliminates the need for adjustments and extremely low maintenance. I tried dual Z rods, but since I only have one Z motor driver the gantry was never perfectly level... also it's impossible to completely get rid of wobble, so belted Z is definitively the way to go! Yeah, this runs Klipper.

I haven't really kept track of the cost, but just scanning some prices online, around 300 dollars for new parts. I got a lot of stuff second-hand and the original printer for next to nothing so it didn't hurt my wallet that bad :)

Thanks! Looking up close in person there is some slight ringing around the holes on the hull, but I was really surprised it came out looking this smooth and with no extrusion issues using a 0.4mm nozzle.

All the things :D

Really great results. No more overhang issues at high speeds which I was constantly getting before the upgrade. The old setup used a dual 5015 setup and even at 100% they could not keep up.

Sadly there are no moving parts on this model. If you know your way around a CAD then it seems to me like it's possible to modify the notch where the slide joins the frame to get some action.

Thanks! Sadly never found time to finish it, but might revisit it some day. I actually started on an improved version where the original MIX files were used in the browser and no pre- extraction + conversion needed... would be cool to finish that.

@AndersEvenrud I think if you do find the time, it would get some serious press coverage. I looked at the engine stuff and I've got to say you've done a cracking job. What was your history with game development before this? Or was it a case of rewriting the original source into TS ? Either way, great stuff !

​@@internetoldie That was my first proper game project. I was very familiar with browser APIs from general web development / work experience, so the engine went fairly smooth. But the game mechanics, graphics and whatnot was quite a challenge and kinda where things slowed down. The only references I used in development were the data files and documentation found in the wild.

It's a web application desktop environment written in JavaScript designed for the browser. Runs in Electron as well though.

This just runs within the browser.

Hey! Glad you like it :) You're right, there's no datagrid component shipped currently. The reason is that there's already so many things like this out there, and pretty much all of these can be used with relative ease by application developers. As for database connections, this just requires writing a service provider with a database library from npm. I don't have any tutorials or anything on this, but now that you've mentioned it, I feel that could be a really good idea. Just hit me with any question you might have. Preferably by email (my username at gmail.com), or drop by in the Gitter chat room for some DMs.

Listening back to this now, the noise is obvious. I think I recorded this on a crappy laptop back in the day where the speakers was unable to reproduce it :D Thanks!

Yes, you can. You have to host it yourself though.

@@andersevenrud Thanks for your reply. Keep up the great work.

Sorry, I have no idea.
