Some friends just acquired the above mentioned machine and I brought over a test program that runs fine on my Haas machines. No luck, as the arc moves seemed to confuse it....the spindle just tried to drift off in a direction it wasn't supposed to go. The Mach 3 software didn't give me an "unrecognized code" error so I assume the format of the G02/G03 statements was off, due to a bad choice of post-processor. The support section is down on the K2CNC website, so that's no help. I looked over a bunch of programs that the previous owner of the machine had and NONE of them had any arc moves...just lots of tiny straight lines approximating arcs. That scared me. These machines DO arc moves, right? If so, does someone have a G02 or G03 statement that works on their machine they'd like to share?

Thanks!

Does the toolpath display look correct? If not, the IJ mode may be set incorrectly in Mach3.
Can you post the code?

Well, one post I used made the output: G03 X4.1478 Y1.2607 R.125. The other post put it out as: G03 4.1478 Y1.2607 I0 J.125 Think I was using the "R" one...will try the I J later. Thanks.
