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.
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.
