I’m not ready to make the jump to Klipper just yet. I want to iron out hardware issues first.
I have a couple important takeaways. First, build the damn thing to be actually rigid out of the box. I thought I could keep it cheap with only 2020 extrusions, but I’m honestly paying a helluva lot more to add some stiffness to it.
Second, plan for your wiring at any given point to double. I got really tidy with my wiring at first and now it’s an absolute nightmare. I gave up and half of it dangles off the back on the floor. It works but I really could have done a lot better with some better planning. It is truly a shameful sight.
I did add an extra pair of motors to the Z axis, bringing me to a grand total of four. I’m waiting on some stepper drivers to get it going again.
I don’t have any pictures on hand, but could take some later.

I built myself a 400x400x500 CoreXY machine from scratch.
Honestly, my prints are dogshit unless I go slow, and then sometimes they’re dogshit anyway. I have found the entire exercise as one of futility and massive frustration… but I low key love fucking with it. I can’t help myself, I keep building upgrades and improvements for it. I keep sinking time and energy I don’t have (and cash that I do) into this fucking heap of shit and I can’t help but love it to pieces. It’s dumb as fuck and it’s pretty fun to work on.
Honestly the vibes are about the same for a project car. Don’t daily it or you will hate yourself, but if you put it together and tune it right, you’ll have a blast.

Haha! I had a Mini T as my first one. It was a fun little car!

Check out the Tarmo project. I’ve been wanting to put one together for a while.

I think you might be onto something but the other direction. I think it’s not moving quite enough per layer.

I haven’t run a temp tower. I’m not fully convinced that it won’t damage itself so I’ve been trying to think through it before trying another print.

Yep! It actually extrudes just fine. I’m starting to wonder if maybe my z axis e-steps are just slightly off and it’s enough to compound over the course of the print. It seems to hit a certain spot and start grinding itself into the print, which suggests that it might not be moving up enough per layer.

I’d be surprised if it was too cold, but I’ve heard stranger. This is PETG at 250. I’ve actually pulled the nozzle and Bowden tube and pushed a very small Allen key through, so it shouldn’t be clogged.
Z height is calibrated, and I’ve calibrated the e-steps for the z axis. I’ve tried disabling the fade height to see if that was doing something but it didn’t seem to make a difference.
I ran through calibrating the extrusion e-steps. It’s feeding 100mm when I tell it to do so. I haven’t messed with the extrusion multiplier, do you have any information about that?
- Comment on Troubleshooting a fully custom build 9 months ago:
Yep. I calibrated all the e-steps too. Not just the extruder, but the the movement e-steps as well.

If you’re concerned about durability, you could potentially add in some bolts to use as a slip-in rigid spine to further reinforce the design. I’m thinking something similar to how concrete is tensioned to provide rigidity and strength.
I’m spitballing ideas to see if I can spark something workable for you.

What retraction settings do you have? I’m wondering if maybe that’s contributing to your jamming.

No need to get a purpose built dryer actually. Your heated bed will actually do exactly what you need. Flip a plastic container upside down over the bed with your filament underneath, set the bed to ~50-60C for PLA, and let it go for a couple hours.
