My New Chonk build rear z motor doesn't move during homing.
Hmmm... I wonder if you're using a toolboard, couldn't it be wired like a VC3/4 with all independant Z steppers? (skipping ZMB)

Hmmmm, all that looks good as far as I can tell. And your wiring sounds like it's correct to what I'd expect... sorry, but it sounds like something more complicated than I can help with. 😕

Also, I believe the skrat config that seems like it should be used is the standard config.cfg and specifically NOT the config-3z.cfg (in case that somehow attached itself to the config)

Just going to drop this info in here... the only odd thing I noticed looking at the printer-definition.json of the V-Chonk is that axis "z" is missing the performanceMode entry that all other axes seem to have

Looks like the stepper_buzz commands shoudl be -
STEPPER_BUZZ STEPPER=stepper_z
STEPPER_BUZZ STEPPER=stepper_z1
Although maybe that should be z0 and z1 ? The universality of the configuration files has me a bit confused with this out-of-the-ordinary printer's Z configuration

I'm also thinking that doing a stepper_buzz on Z0 and Z1 might be telling, but I don't remember the actual structure of the command (and the stepper naming convention it needs)

You should probably post your printer.cfg... I also would be interested to see a pic of your MCU and how's it's wired

Thats not bad... did you leave it heated for a while before checking? Usually heat soaking a bit longer gets a more true reading as the heat is still spreading to the edges for a while

Agreed, I think that looks good at this point... no peak that carries across the whole bed, and you're right about getting that magnet & plate on there before you see the real end numbers

MUCH better... what do you mean by your Y rails are duck-footed? They toe outward towards the front/aren't parallel?

LOL, I guess if you're going to babysit a print, might as well make it worth it!

Someone likely had good intentions with that design, but neglected to think about the reality of manufactured parts not matching CAD

Yup, that is what I had assumed... personally, I think the easiest fix would be to print one/both of the joiner prints without a "bottom" of the pocket for the gantry tube and just allow it to float until the gantry is in place

I hand-made a carbon gantry tube, but realized before I assembled it that allowing the mounting to float there slightly was actually more ideal anyway (it avoids a set X distance required for the linear rails). I also did some abnormal sandwiching in the attachment of my gantry tube which locks the entire thing plate-to-plate, and opening those holes to slight slots just made sense for that. Truly, my own reasoning behind it, I like to experiment with this printer (VC3) quite a bit

I assume that your level check of the bed was in relation to a frame that is level... if the frame isn't level, then the bed not being level wouldn't really have any relevance

Tramming is mostly assuring that the axes of movement are all perpendicular to each other properly...
