Hi Tim, Sorry to disturb you again.
Just wanted to confirm that do you experience this weird symptom or not with RPi 3. I had tested the sample PCB gcode file from thls link https://www.theremino.com/wp-content/uploads/files/Theremino_CNC_V4.9.zip With the sample \Theremino_CNC\GCodes\PCB Large\Alim1 ( optim 1m ) ( mill 1_40_25).gc milling everything look normal, the stepping motors can return origin location. But when minimised the MachineKit window, everything look weird, 1) stepper motors running faster, not according to the feeding velocity 2) stepper motors missed steps, cannot return to origin location after complete milling (G00 X0.000 Y0.000 z10.000) it took about 1.45 hrs Regards, KL Chin On Thursday, 9 August 2018 22:04:14 UTC+8, Timothy March wrote: > > Thank you KL Chin > > Tim > -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
