Spent all weekend assembling this Core One. It probably took 14 hours in total. 12 hours to build and 2 hours to troubleshoot issues. Broke some parts made some mistakes but I finished the build.

I stared a lot at the red circle thinking that you were trying to point something out.
LOL I didn’t even notice
Nice! I rember almost stripping a few plastic threads and then hoping for the best. So far so good. I hope you lots of fun and productive printing.
Thank you! I spent the whole day learning FreeCAD. Made a case for a ESP32 board.
Hey congratulations! I hope you enjoy owning a printer!
I had a very similar experience building my first printer (a Prusa MK3S) a bit over five years ago. I’ve rebuilt it a couple of times since.
That experience is serving me well as I build a Voron 2.4R2 (with ASA parts printed on the MK3S). The learning curve part appears to be largely behind me, and owning the Prusa did help ease that since they make a lot of things pretty easy.
Thanks!
Fellow Voron builder. I agree that getting reps in on other things made the build a lot easier. I found the mechanical portion of the build very straightforward thanks to things like flat pack furniture and Legos - it’s basically being able to follow well documented spacial instructions. Wiring wasn’t particularly difficult, but I’ve crimped things and built wiring harnesses before. The thing I was the most apprehensive about was getting the pi running and the initial tune, but everything is so well documented even that was pretty straightforward.
The Voron build is absolutely long, but it’s surprisingly approachable and well thought out. I guess that’s why there hasn’t been a revision in a while.
I agree that the part design is superb, especially coming from the Prusa MK3S. The Voron build manual blows Prusa’s out of the water. I find the whole thing way more intuitive and enjoyable to build.
Fortunately for me, Linux and SBCs are well within my wheelhouse, and that was one of the primary reasons I chose to build a Voron.
Nice, hope your’s runs better than mine.
I’m not going to say it was smooth sailing but I think I’m through the rough waters. This past day I’ve been printing basically non-stop and every print has been pretty much flawless.
The days before this though I had:
- Diagnose z-axis movement issues.
- Accidentally printed PETG onto the smooth bed plate. (I knew this was bad but I just assumed it was bad adhesion, I didn’t realize the problem was the opposite LOL)
- Broke the belt tension adjustment piece and had to drill holes into it to remove it and replace it with a piece I printed with PETG.
- Diagnose a “ghost clog” where I took off the nozzle, found no clog, took apart the nextruder and found nothing and realized at the end it was bad filament.
- I wasn’t even able to put the printer together without reading the comments pointing to waaay too many flaws in the instructions.
- Well, I learned that with the smooth plate the hard way too.
- Don’t get me started on that one. The nut in the ajustmend-thingy broke loose on mine, after I had to tentioned the belts way too often, cause the Axis bent. I had to saw the screw of at the front to get it out. Whole process took me about a month.
- I put the spacer hooks of the heatbed on the wrong way, and changing them when the printer is essembled. Well, a friend who repairs washing mashines for a living helped me out.
- The ghost clog is interesting too. I’m on my third nozzle now, trying to clean number two and three. Seems like a clog on the seperation of filament in front of the vulcano-split (high flow) and by the love of god I can’t seem to het them unclogged. I soked them in cemecals to break the plastic-chains. The design is so annoying to get to in any way, cause at least as a amateur, you only realize the clog when its too late. (and I know that that might break some cotings of the hardened steel nozzle, but a this point, I tried anything else) So yea, I hope you’re printing adventure is smoother than mine.
Oof that sounds rough. I hope it’s all fine now.
This may be a shot in the dark but I just inherited an old printer. Its been collecting dust for a while, since it was made essentially, ~ 2022. Lots of upgrades seem to be done to it but idk how to do anything fdm printing though. Its an ender 5. Anyone have any advice for me on where to start? It seems a little boujie!
You might get more luck with responses by making a new post.
What broke, why and how?
I broke one of the tension adjustment pulley thing. I loosened the belts to calibrate the y axis. When I was tightening the tension belt I absentmindedly tightened the bolt all the way and then some which broke something. Not sure what but turning that bolt now no longer moves the tension belt pulley. I can see the screw spinning so it’s not a stripped screw.
I’m going to look into what actually broke in a few days. Kind of exhausted from assembling the thing. As a result of this the top belt is a bit tight (its like 105HZ) but the prints come out ok-ish so I’m not in a rush to fix it.
Obviously, your next print is a replacement tension adjustment pulley thing, as is tradition.
I have some PETG filament on the way which is another reason why I haven’t looked at the issue yet. All I have is PLA at the moment.
I don’t know how critical this part is but if it sees any kind of load, re-pint in abs/ASA or better. Petg and PLA creep under consent load.
It’s pretty critical. It holds one of the pulleys that the belt is attached to. The belt moves the print head in the x/y axis. I actually did print the part in PETG. Hopefully it just works and I won’t have to touch it for a year :D
You will definitely want to reprint it in something else while the printer is working. Otherwise you’re going to see dimensional accuracy issues crop up over time that require you to keep adjusting the belts.
I can’t really print it in a better material until I get ventilation figured out which might not be until spring of next year. I did order some parts from Prusa in case the part I printed fails so worst case I have to swap it out but so far it works very well :D
Gotta give it to them for making the machine so repairable. Even if the design here is a bit questionable.
