Hi all. I’ve been lurking here for a while, gathering info and reading as much as I could while I got my setup put together. I have been taking it slow (mainly due to holiday shenanigans and watching after the kiddos). I got all set up finally this evening, and have been working on calibration. I’m having odd motor movement behavior though.
My setup is:
1.5” square tube frame
12’ motor spacing on a 13’ top bar
Full 49”x97” 3/4 MDF wasteboard
Chains over top with a simple counterweight setup
Makerverse 1.1.2 on a pi 3b+ with a 7” touch LCD
Firmware updated to 51.28
So I connect to my new machine, leave the default workspace settings, hit connect. It prompts to start calibration. Stepping through the tabs:
First few go fine
Z-Axis: left and right motors hum, z never moves. I understand this could be due to never having defined a home through the set chains process.
Skip to the chains tab. I had already adjusted my chains to have the sled hanging as close to home as I could (center of wasteboard). I take it off, connect chains together, and get started. Make a big step in the positive Y by 500mm. Goes fine. 100mm. Goes fine. Decide to do smaller steps rest of the way up. 50mm. Goes fine twice. Then the next attempt at 50mm and the motors hum but don’t turn. Wiggle all the cable ends, try again. Goes. Next time fails. Wiggle cables. Fails. Down 50mm. Fails. Up 50mm. Fails. None of these failures are tripping alarms in the terminal window. I decided to try the X movements. Move X left and then right. No issues. Try Y again, still just motor hum. I’m so confused. At this point, every X move is successful and every Y move fails up or down. At first I thought it was a connection issue, but that wouldn’t explain all the successful X moves.
I’m sure it’s something simple, but what am I missing here?
