Can you confirm if jogging controls work in the intended direction? Left moves left, right moves right, up moves up, and down moves down?

Please run these commands in Console and return all output:


ok in the move box left and right is ok. up it moves laser down. down is up. you still want me to run the $


Also, take a screenshot of Edit->Device Settings please.

Your machine’s behavior doesn’t seem to match expected default. Not sure why that would be.

But try this. Run this in Console:


That should resolve jogging direction. However, this might negate the homing direction fix that you put in earlier.

If homing fails then revert the homing direction to default:


After all is working home the laser and run these tests:

  1. Check jogging direction
  2. Using “Get Position” in Move window check that post-home location is 0,0
  3. Check that position increments as you move to the right and down
  4. If all those pass, then run a frame test

If anything doesn’t work as expected report back with results please.

it did change the home $23=7 fixed the homing to the rear left. i framed a small box in 3 locates seams to be ok now

Great. Hope it goes well for you then.
