I changed your code to cut 1/4" & slower. Here is a pic of how it turned out.
I must have some backlash but I can not measure it with a dial.
I also tried to load the gcode into LazyCam & had an unrecoverable error.

I took out the 1 1/2" circle, put it into Mach3Mill & then loaded it into LazyCam. The top & bottom look OK but the right & left sides do not & thats where I had the problems with being off. Here is the code.

I can't figure out how to use the wizard. Here is the extracted code from the Gcode for the 1/2" circle. It looks good to me. Maybe you can see something.

Had 2 - 1/2" circles & they turned out to be rounded squares. Had a 1 1/2" circle & it was better but had some small flats. Useing an 1/8" bit.

I tested the X & Y with a dial & they both came out to "0" backlash. I built this machine very tight so I'm not supprised. Maybe I was running to fast. Any other suggestions?

Thanks

Chip
Thanks

The flat spots are on both X & Y. I'm in no hurry so I'll wait till I get the Dial...Just want to get it right so I can sell it. I'm about done with my new machine.

Having a problem cutting circles. They don't come out exactly round. There will be a small flat spot on one side. The machine cuts squares within .002".
