Check the set screw like jake suggested.
I will tomorrow AM. That still does not explain why x axis jogs the opposite way sometimes (when it does engage). I appreciate all the input.
The other option I can think of right now is update to 1.0.4 first. and reset in general, select your machine, and reboot.
Could this be a result of a single loose wire in the connector? I know the cimp pins on those amphenol connectors can be a little finicky. I could imagine that if one wire was making intermittent connection to just one of the two coils in the stepper motor, the motor direction could become unpredictable.
I have a feeling this is what’s going on as well. You could also unplug the y cables and the x and plug the y cable into the x motor and see if it will drive it to test that theory out.
Thank you all for all the help. It looks like the wire is the problem. I switches the z and x and now the z is doing the same.
I do not think the connectors are loose, it almost seems the wire is reversed on one end somewhere… The z slider goes in reverse or just stalls and whirs
if you can send an email to firstname.lastname@example.org and included a video we’ll get you fixed up asap!
Done. Thank you very much!
. We got you bud! No worries
When I got my machine the Z-axis was having a similar problem. There was a blue wire that was making an intermittent connection at the plug. I stripped the wire back and rigged up a temporary connection and let support know. They fixed me up by supplying a replacement cable. That did the trick.
Interesting. I have the same exact issue. THe blue wire is loose. I am waiting for onefinity to respond how to get the metal connector out of the plastic enclosure so i can recrimp the wire.
I got it working. Figured out how to get the metal connector out and re crimp. All good. THANK YOU ALL for helping out!!
Man thats awesome! Glad you got it figured out. Maybe we need to start a troubleshooting thread listing issues we have encountered and the fixes.
Was the wire crimped loosely, or was the crimped wire loose in the plastic plug housing? Awesome you got it going!
I think it was crimped loosely and not stripped enough.
That’s great to hear! Glad you got it working. If you need a replacement cable, just let us know.
Mine just started to make the grinding noise when homing, on the X axis only. Didn’t do it before. But it is homing and does seem to move as expected.
I think that has more to do with stall homing tuning… Try to clear out the dust/debris from the area where the axis’ meet/stall.
I had homing issues as well, right out of the box. 1F’s video helped me tune my X/Y axes so it homes perfectly, every time:
