Carve King finally built, but I ran into a few issues with the test file... First - the test file started great, but would simply quit moving half way through the "R". After 4 test runs, checking the voltage again on all stepper drivers, and jumper connections... Finally, I realized it was stopping at the exact same spot because that's when my Mac screen would go to "sleep". I didn't have the patience to test it a 5th time, so hopefully this is just a tip for future reference. Second - One of my fan blades broke off... still works but I have to clamp down the electronic enclosure because it wants to walk now. Can I just buy another fan? Third - See Pic... Can someone tell me why the Y axis seems to be walking a little? Work piece was clamped tight, so no movement there. I did notice one of my Y motors is not "locked in" when the machine is engaged. Meaning the motor can be turned by spinning the coupler while the machine is plugged in, but the other 3 motors can not be turned by trying to spin the coupler. I originally thought this might be due to how they are plugged into the board, but I swapped (Y to A and A to Y) and still got the same results with the same motor. Four - The cut is not as deep as the first couple of passes I ran... I'm assuming I didn't get my Z axis zeroed low enough on the last run. I'll try to fine tune that on the next round. Thanks in advance!!

Hey. Congrats on the build. On the motor being able to be spun while under power: is the coupler clamped down tightly against both the motor shaft?
Y losing position could be due to a few things such as misalignment of the drive system, v wheels too tight, antibacklash nuts too tight, driver voltage incorrect, or a hardware problem. Confirm that the coupler is tight for me please and let’s go from there.

Thanks for the response, Derek!
Here's what I checked: voltage on all stepper drivers between 65.0 and 65.1, v wheels can all be spun by hand, both Y motor couplers are against the motor shaft and clamped tight (no play in either screw on the couplers). Just FYI, the motor in question in on the Y idler side.
I checked out the antibacklash nuts. I used my feeler gauge to determine if there was any space at all between the adjustment screw and the nut block. The Y idler side isn't even touching the nut.... .35mm of space. The Y motor side has zero space, the smallest feeler gauge I have is a .04mm and that wouldn't slide between it.
As many times as we manually adjusted the gantry during installation, I thought maybe the idler side and the motor side may not be square with each other. But I'm not sure that would answer the motor question...
Thanks for the help and Happy Father's Day to all CNCers!

Thanks for providing that info and thanks for the well Father's Day wishes.
I do want to replace that motor given the info at hand. It's very rare a motor isn't working right, but I've seen one other case recently and since you've checked the other likely culprits I think it's safe to surmise that is it.
Please clarify for me though: Are we talking about needing the long wire motor or the short wire motor. I'm assuming when you say idler side you are referring to the back right since the end plate on the right side is the idler side. Do I have that correct.
Also please PM me the name that you ordered under. I was trying to find it by your registration email but didn't see it.
Thanks Derek
