I've been trying to teach myself gcode and so far sucessful except for milling circles.
I'm trying to mill a 22mm circle at X:21.15 Y:25.5 with a 6mm mill in Mach3.

Problem is, my code just seems to make spirals all over the place.
Would anyone be able to put me out of my misery? I have searched on google for answers, but I just can't a straight answer to what i'm looking for.

Thanks!

first try to seeing how start and endpoints are defined..

next I guessing you use absolute cordinatas for lines and endpoints and relative cordinatas for arc centers..

if advice can be given, make circles of two half..

if full circle defined ... that in circumstances, the controller can evaluate wrong..


do you have g-code editor?
a gcode editor draws on the screen promptly your code.. without you risk to crash your equipment..

they are very basic.. but if you stick with gcode editing then you need later a more professional version..

What kind of machine and controller? Are the coords you give the center of the circle? Is the 22mm what you want on the outside or inside of the cutter? Are you using cutter compensation? Depth?
