Hello,
I'm starting out and playing with lcam and Mach3. I posted from LCAM to Mach3 and got "Bad number format on line 153." line 153 is:

N770 M6 T(TOOL Change)

Any pointers or good reference material to figure out how to solve this type of problem would be greatly appreciated.

Hi, Shepard

I think you need to add/edit in a tool # "0",  N770 M6 T0 (TOOL Change), LC depending which ver. your running, even latest, still needs some work.

Hope this Helps, Chip

That got it! thanks
