Like the title says, anything over 50 in per minute is risking disaster. I’ve had the same issues on other stepper motors when the drag exceeds the power of the stepper and it loses zero and locks up. In this case the Carriage is not binding, it appears to be solely a ball nut issue or a motor controller issue…
any ideas?
or…is it the coupler between the motor and the threaded shaft?
there have been some instances of this happening…the coupler slips…
Excellent suggestion. It sounds like a stall but i will definitely look at that tomorrow!
Try to loosen your lead nuts and readjust. Sounds like theyre binding
I found the problem, the lead screw coupler and shaft of the motor are not all in alignment the only way I can get this to work is by loosening both bolts of the y-axis motor so that it can wobble around a bit I looked at the lead screws and looks like they have been ground off square
so something was not made right?
take pictures and send them to Langmuir support…
I need to take it apart and see if the lead screw or the coupler or both are off. If both are off I might be able to turn one in relation to the other to help mitigate. I could also put a Lovejoy coupler in for misalignment. I will try Sunday night to diagnose it further.
Removing the bottom bolt from the motor mount to the y-axis pipe and leaving the top one snug is allowing me to run it without problems but you can see the motor wobbling
I’ll add to this now that it’s running and I’m working my way through my software knowledge overall I am much happier with this purchase than I was initially. all my previous comments about customer service or the lack thereof still stand but with the help of forum members I’m running…
I really like the fire share crossfire pro computer stand I cut this morning
glad to hear…
we al know not every company is perfect…but at least Langmuir have a forum…where we and they can learn from.
Measure your motor mount brackets and lead screw brackets. I bet one is either in the wrong spot or they sent you the wrong size. They can get mixed up easily and installed in the wrong spot. There were a few others here that did the same
