So last night I was trying to get this working by taking a page from the MPCNC playbook and wiring the motors in series. I ended up having a bunch of problems with skipping. Well tonight, with a clearer head, I tried it without the belt even attached and they are just a mess. Same skipping and studdering I thought was being caused by tension or not being synced. Apparently the motors I have don’t play nice wired in series. Once I wired them parallel, everything evened out nicely. Here’s some pics.
I chose the Piper as my test platform because it was a lot easier to add the second motor.
Had two skips. First on layer 2, but I think this might have been a physical collision because my starting Z-height isn’t at it’s best. second one was about 60% up.
Layers and corners don’t look that terrible.
So this was dual X motors, wire parallel, at 150mm/sec feed rate, 1000mm/sec acceleration, 50% infill. I increased the flow rate up 20%, I dunno, I figured it needed a little help keeping up? Print took about 18 minutes.
