All, I have switched from Shapoko XXl To the Millright Mega V. I am new to UGS. I have set the Job zero's but when I try to start the job the Z axis travels to the top and trips the homing switch causing and error and pause to the job. I cannot clear the alarm and tell it to continue it is requiring me to rehome the machine. I the g code the first Z axis command I see I hi-lighted in red. is this an indiacation of the Z travel ? if it is can I change it before I start the job?

The millwright mega v uses a customised version of grbl (it enables 4th axis control), but I wasn't able to find out much more about it. What cad-cam software and post processor are you using to create your g-code? And what does the manufacturer recommend? I notice that your g-code doesn't specify which workplace coordinates system is to be used. Alex.
Obvious question, but did you home your machine before setting the workplace coordinates system zero (set XYZ), and did you set the workplace zero in the same place on your workpiece as you set the origin in Vectric? Alex.
If you post your V-carve file and g-code file we could have a look at them to see what the issue might be (tomorrow in my case as it's nearly bed time here - UK). Alex.
Pretty sure everything would be fine if you took out that line (or changed it to G53 G0Z0 or G53 Z0Z-0.25 or something just to be safe). It's just a safe Z move for starting the spindle, but clearly it doesn't work here if you don't have 1.7" of travel above the workpiece. You should be able to fix this permanently by setting your safe Z height in your CAM package. It's written in G54 coordinates, which doesn't seem very helpful to me, since you want it to be just below your Z home position (defined in G53 coords)
