Stalling Grinding sometimes on startup.
Sometimes when I fire up the machine and machine auto homes the stepper will stall/grind.
I cycle the power and they home smooth as glass.
I also had a vector problem (multiple over laying lines) that cause the steppers to stall today but when I deleted the over laying vectors the stalling cleared up, added the over laying vectors via undo and they would stall again. Not knowing for sure what was at fault for the problem I contacted LB. The guys over at Lightburn said it must be my setting, like acceleration.
Can someone take a look at my setting and see if anything sticks out to them? TIA

Hi, when looking ata the $ settings, two items do stand out which might cause an issue:
$120=13000.000 the acceleration is way to high, rather use something like 8000
$28=11 seems a very high PWM frequency, I rather would use something like 5 (=1kHz)
Try that and see if it improves. If you're after high speed then you need to lower the micro steps from 16 to 8. Just remove MS3 jumper under each set driver pcb and half the $110 and $111 settings (make them 80)
Cheers!
