PRINT LOAD ERROR on job that worked once

I was running a 2nd set of 5 coins.
pass 1: engrave and cut
pass 2: engrave

After getting the first set of 5 coins completed, the 2nd set of coins performed pass 1 ok, then i received this message during pass 2.

This feels like a cloud issue. I guess I have nothing to do but reboot the laser. Hopefully the new saving of jobs online means that I don’t lose the registration.

We’re sorry, an error occurred while preparing this print.
Error:FATAL_PRINT_ERROR:MOTION_PLANNING_ERROR Error: Bad response from server for /api/prints KMY-749

A reboot of the laser got rid of this error and I was able to continue to job without losing anything.

The times that I have seen that error is when I try to click Print too quickly after one part of the job is done (before the lens is recalibrated after the job is completed).


Thanks for letting us know about this, and I’m so sorry for the trouble. We’re seeing this error too, and we’re looking into it now. I apologize that I don’t have any further details to share at this time.
