  • 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.





  • Because I hate when people ask questions and never go back to update their original post when they solve the issue, I’m gonna post an update here and now.

    The fix was actually surprising but simple. I ended up moving the second Z axis lead screw carriage mount a bit further towards the motor. That is, the piece that supports the build plate, where it connects to the leadscrew.

    Further diagnostics ended up showing me that it was binding, and one of the problems I had later on was that it was binding but only when going up. So I ended up having prints that got progressively more and more stretched out along the z axis.

    Moving it to be further in line and loosening a few mount screws to allow the nut to come back to vertical got me to where I needed to be. Hope this helps!







  • 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?
