I think this is a mistake. I operated this way for about a year and suffered quite a few crashes until I fitted
decent home switches. I reduced the number of crashes by over 95%. I now regard good home switches as a must.
I agree wholeheartedly, but that's a separate issue.
If run the gcode in a different simulator, and I see no out-of-bounds moves. The tool stays in the area I'd expect it to.
But, when I load it up in Mach3 and look at the tool path tab, I see this:
.
Note the big vertical red line, which is about where the carriage tries to go when I run the program.
Note the "program limits" values, and the nice dotted red line going from the end of the last tool path to a point 54" south and 14" east.
I'm attaching the gcode in case anyone feels like looking at it and pointing out what I'm doing wrong. (SURELY this is my fault, but I'm at a loss as to how / why.)
Thanks for your time.
