Pretty sure my machine just cooked my rotary

Have a pretty much new RA2 and iv only tested it a couple of times but works fine. Fast forward to today and I hook it up to my Pronto 40 and start getting ready to hit the test button but something smells like electrical burning and I realize it’s the motor on my rotary that was heating up with nothing being pressed and now I’m pretty sure it’s burned the windings in it up so…….yay

Is this a controller issue on the Prontos side? I’m super irritated mainly because I have no clue what could have even began to happen

I got an OMTech about 5 years back. The motor drivers were set to twice the limit of my motors. I only noticed it because

Check the settings on your rotary, you can usually set holding current also. If the motor driver is within specifications and the working, then you lost a motor. The motor drivers also have a red error indicator on them.

Is the holding current set through the switches or through the machine console? It would make sense that the holding current was far too high and I suppose I could just rewind the motor but I’ll wait to break the motor apart until omtech support calls back

Okay iv done some digging I 100% lost the motor, so I need to see if I’m thinking about this correctly, I plugged the rotary in and flipped the switch and I think that’s where I messed up? I should’ve enabled it in lightburn prior to flipping that switch because if you enable the rotary in lightburn and turn the switch off on the machine then the Y axis motor acts like it’s not current enough current so I’m thinking I may have made a mistake(not a super costly one but meh)

Wait for OMTech to help you out. They will replace what’s wrong, at least that’s the theory.

There are current limiting settings on the motor driver. Check your type of NEMA motor and see it’s maximum current.

A NEMA17 is 1.7" across each side..

This is a direct replacement for the stepper motor on the rotary so I ordered one because it’s super cheap, thank you for helping me so much today haha whoever put together the drive panel on my omtech is awesome, I figured it would be a mess in there but everything is organized and well labeled
