Z moves are very slow

LightBurn Software Questions
1

Need to edit this post.All I did was click on it and it posted it as mine. I did not originate this post.

The problem I have is the z axes moving very slow when using the move diolog. It seems to stutter while moving up or down and the only way I can stop the movement is to click on the stop button in the laser diolog. Thought the stepper motor was going out. Pluged the z into the y port and it moved as it should.
Went to easel and the xyz moved as they should. Also works ok using the off line controller. Do I have a command that got messed up lightburn? Thanks

Z moves have their own independent speed value for movement, because they often can’t match the speed of the X/Y table. Have you set the Z speed?

I have my Z speed set to 25. Where do I find the “focus Z” button? Don’t have one…that I can find.

4

The Focus Z button only appears for controllers that have a focus probe, and GRBL doesn’t.

Still have the same problem. Z moves with a stutter and very slow.

6

I reinstallled ver909 and still the same. Slow in all directions. Z still stutters

UPDATE
The laser moves like it should when burning. The original problem still exists.

Did you check the stepper drivers if they have the same configuration (dip switches)?

9

What is the firmware setting for maximum speed of the Z axis? ($112 in GRBL settings)

10

Do not have stepper dip switches

I will check the setting on $112 when I get back to the shop. Still don’t understand why things would change for Lightburn. All works well in other programs.

I have no idea - Z moves are just emitted like anything else, with G1 Z### F### (and the #'s are filled in with the appropriate values from the UI). You can just enter a G1 Z move into the console. If it works there, but not when clicking a move button, then something is up. If it moves the same in the console as with the move button, then you have a setting issue.
