Having some issues with my steppers.
I got these off of Amazon (STEPPERONLINE 5PCS Nema 17 Stepper Motor Bipolar 2A 84oz.in 48mm 4-Lead for 3D Printer/CNC).
While testing a simple diagonal X/Y movement test at max speed, sometimes it works with no issue and other times the X and/or the Y axis will “chatter” or seemingly bind up randomly??
In the attached vid, at the end the X axis binds up and stops moving.
You cannot see in the vid, but the axis is not colliding with X/Y origin, it began chattering about 20~30 mm from the end and is now out of sync. The chattering sound sounds a bit like you were holding the stepper.
Before and after I checked and with the power off there is no mechanical interference, just the load of the non-powered steppers. Any help would be appreciated.
I didn’t see the video, but 90mm/s is pretty fast. I would expect some non smooth motion to happen. I think that might be over the speed limit set in the firmware, actually.
Yep, I was trying to push the speed to max to see if I could make the issue present itself as it occurs randomly. I have performed several test cuts using Aspire with no issues, but there were no long X/Y movements. When used Fusion 360 to gen the Gcode, I setup to drill my spoil board for threaded inserts this issue occurred. But I have only cut a few tests so far.
Can you recommend a max speed for X / Y movement (no cutting load) and I’ll test at that speed?
Also when I first setup the X / Y axis I noticed that if I moved by hand the X or Y too quickly the unpowered motors would also “chatter” in a somewhat similar way.
If you are familiar, do you know of any quality issues with steppers from omc-stepperonline.com?
