X Carve Y Stepper motors not in sync, or binding

Hi Everybody,

After working really smoothly for 1 month, the Y1 stepper motor isn’t working in synch with Y2. The Y2 will move4-5 times before the Y1 will lurch forward or backward an inch or so. It feels like it is wrenching the motor when it does this and I am afraid something will break. I have tightened the eccentric spaces and wheels on that side as it seemed like they were a little loose. I also tightened belts on both sides. Any help will be appreciated.
Thanks

Turn everything off and check the wiring on your Y1. It sounds like it’s being dragged.

Thanks. It looks like the Y1 isn’t working, like you said. THere was a wire loose, but that didn’t seem to be the problem.

Triple check the wiring (with the controller powered off).

It’s possible that the driver is fried due to an intermittent connection. With the power off, swap Y1 and Y2, power on, what happens?

Thanks Neil,

You were right. Y1 works now, but Y2 doesn’t. DOes that mean that the driver is fried? How do I rectify that?

Thanks

I have same problem…hi haldor…brand new tb6600’driver upgrade…z ok x ok but y1 is turning at a much smaller steps/mm compared to y 2 so it binds up

i havent done any wire swapping driver swapping to isolate…will do that tomorrow…

The settings on both drivers are identical…and they both share same connection coming off stock arduino

Fyi i removed the belts and just viewing the stepper motor shaft …both y motors are definitely not rotating at same steps/mm …y1 much less than y2

Then the microsettings are most likely different between them.
Or driver is a dud.

Microsteps same setting on bothndrivers so im thinking driver is a defect…common with these chaep,chinese knockoffs,will,research more
