I am not sure what is going on, but my machine homes just fine. When reset my zero it moves up for Z+ and down for Z- as it should. When I turn on my machine and run the program through UGS the Z axis goes up and starts the pattern. What gives?
Post the first 20 lines or so of your gcode, this will tell if its a code issue or a hardware issue.
Sounds like maybe a relative vs absolute issue.
Do you have a G90 in your header?

Open the Gcode file and copy and paste the first 20 lines.
Here it is:
Yes, I believe so. I just post the first 20 lines of my gcode file
Also, change $1=25 to 1=255
Are you set to zero off the wasteboard or the material in Vcarve or whatever CAD/CAM program? And if its the wasteboard, are you zeroing off the wasteboard?
I’d expect negative numbers for your Z commands but they are positive, indicating your Z zero should be the wasteboard and not the material surface.
Check your origin point in your CAD/CAM.
I am zeroing off the material in Vcarve desktop, however, I had it on machine surface instead of material surface. Oops.
Where do I change the $1=25 to $1=255? In V-carve?
In UGS you’d type that in the Console input window.
This should fix your issue once you regenerate toolpaths and save them again.
No, through Easel. Press CTRL+SHIFT+D and in the command window type $=255 and press Enter. Done
I don’t have Easel
