Question ive had a consistent issue both with my old OMtech and now with my thunder, after i engrave a project when it cuts out the project it is consistently short on the right side of the design. all mirrors are aligned bed level offset is all good. checked the Pwm rising etc. any ideas? its almost like its losing a step. but the laser is practically new attached is a pic for reference. the left side border measures. 2.24mm the right border measures 1.67mm
One step in troubleshooting could be a test where you mirror your entire design and cut/engrave it to check if the error is also mirrored.
Since you’ve ruled out mirror alignment and mechanical stuff like bed level and PWM settings, I wonder if it could be related to backlash or acceleration settings in your controller. Maybe try running the cut at a slower speed to see if the result changes? Also, are you noticing the same issue across different materials or just one type?
