Back Z Motor error

Hello, my issue is when I home the Z axis the front two motors go up like they’re supposed to, but while the back Z motor goes down. When I go up or down after setting the kinematic zero, all three are going in the right direction. Any help would be greatly appreciated!

I think it might be a bad stepper driver.

check the rear leadscrew motor coupler

The coupler is tight

@miklschmidt would you happen to know what is happening or should I go through it like my x and y motors?

This looks exactly like the x/y issue you had, did it work for x/y to just swap the slots? if so, i think your board is fucked. And you're kind of out of slots.

It’s a brand new board

What about the stepper drivers

Yeah well, it's cursed.

If you swapped the slots and it works then it's obviously not the drivers

miklschmidt•12/11/24, 3:10 PM

drivers also don't fail like this

I accidentally swapped drivers. The x and y shit happened on both old and new boards. So the x and y drivers are in the back and right z slots. I will try and move the z slot and try a new driver when I get home
