Are the units setup correctly? Or is there backlash on one axis?

Just now getting up and running. Doing test cuts in styrofoam. Used circular pocket in Mach Wizard. Result is very noticeable out of round pocket. Is this a known problem or is it my machine? I'll try another code in the mean time.

It's probably you're machine. Try doing some plain circles with G2/G3.

Don't know how to do that. Can you give me the complete gcode. I do know how to type or paste into notepad and then get it into mach3.Originally Posted by ger21
Let's say a 3" dia and .25" deep pocket. Thank you.
What size tool?

Here's a circle and one with pocket, assuming a 1/4" tool.

Thanks so much for being there for us. The code produced a circle 10.25" in diameter. Then I adjusted Mach for 1/2 scale. The smaller one more clearly shows the defect (flat spots). What do you think?
In the general config, make sure your IJ mode is set to incremental. that should make the circle 3". Looks like backlash on 1 axis.

That's the one word I didn't want to hear. Worked so hard to make sure I wouldn't have any. I bet you know a code that would reveal whether it's the X or the Y.
It's in whatever axis is up and down in your pic.

Okay. That would be my Y. I'll check for play. I know there's an electronic adjustment also. Does that really work?

It was already there. What else would make the circle larger than the code specified?
