Hi all, newbie here.
I have a large program I generated with MeshCAM 4megs of g-codes that when I load into Mach3 I cannot get the motors to run in mm's. I've set the units on the settings tab to mm, saved the config under the config menu dropdown (don't know what I saving here exactly). First Z move is to 47.10, the motor starts moving up then slams into the limit switch at about 1.5 (inches). I tried putting a G21 at the top of the code with no luck. What am I missing? Either the program is confusing Mach3 or I have another issue somewhere? Can someone point me in the correct direction, I sure would appreciate it.
Will
