I am new to CNC and to Mach 3. Things have been going well except for one problem, and hoping to find some help here. Mach 3 will randomly freeze at the start of running a project and it is always on this line: N140G00G43Z0.8000H1.
For example: I set up the machine, wood, etc. then load the G-code then hit start. 3 out of 4 times everything runs fine. But every 3 jobs or so, the spindle starts and nothing else happens. It is always on that one line of code. I can run the same project 3 times in a row, but it will freeze on the 4th. And nothing in the G-code has changed. I can load a G-code one time and it will freeze. Then I can shut down Mach, restart it, load the same G-code and it runs fine.
Can anyone give a newbie some advice on this? It is seriously slowing me down when I have to shut down and restart Mach every 3 or 4 runs... and time is money.
