Hi. I am a new to gcode and cnc. Trying very hard to learn the basics. I have a harbor freight mill I converted and I am running mach 3. I am having a hard time running a very simple program. The problem is with the tool offset. The program will run sometimes once and sometimes not at all. If it runs right, I will try and rewind it and run it again and it just goes crazy. Cutting anywhere and not following any gcode. I setup the tool diameter in mach 3 at .250.
What am I doing wrong. It will run without the g41, but then the offset it wrong. It has something to do with g41 I am pretty sure.
Here is my code:
%part 1%
G20 G91 G41
G0 X.50 Y.50 Z0
G1 Z -.05 F10
G1 Y1
G1 X1
G1 Y-1
G1 X-1
Any explanation of this would be greatly appreciated.
Thank you,
Michael
