Hi guys. 1st post here and well..yeah is about a problem..
I recently upgraded my computer (Win7) and cnc program to Mach3 v3. ,running on a Warthog. Set up M3 to the max of my knowledge,like 2 weeks ago. its cuts but..always when starting a job cuts a double circle on the bottom left side corner. Cant figure out what it is. thinking on setting up M3 on XP based PC,see if that helps, or reinstalling the drivers and registry thingy. Oh i also used a wizard for a circle thing that really looks  alike to the ones embedded on the g-codes.

here is the gcode I'm using created with enroute 3:

I've included a pic also of the double circle things..hope it helps. Thanks for any help or advice...

Hi Jamuto - welcome to the forum.

Your code uses incremental IJ arcs but you have Mach set in absolute IJ mode. Either set Mach to incremental on config/gen config screen. OR put a G91.1 at the beginning of your code.

Cheers

Thank you Stirling now is cutting well!Double passing but cutting
by the way what is the best way to cut incremental or absolute?
Thanks again

No worries.

by the way what is the best way to cut incremental or absolute?

That, as they say, is a very good question. Unfortunately I'm not sure what the good answer is.

best way to cut incremental or absolute

There are two ways that gcode that can be written relative to a reference. The controller must be able to interpret either
coding. So by default you need to run in one mode or the other. Guess one could can write the gcode with a combination of style 
but that seems like asking for trouble. Depends on how the drawing was done and how you may want to check the code. So there are advantages and disadvantages from a coding point of view. But all this is somewhat irrelavant to your question.

I don't think the actual cutting is the true question as the machine will go where instructed to go.
I can't answer to which method may have some significant influence on the computer side of things.

So after a few lines of typing here, I also am not sure what the good answer is .
