Hey guys,

I have two of Shaoge Chinese CNC controllers (the SMC 5-5, and the 4-4). And neither of them will scribe a smooth circle, no matter what parameters I change. My circles come out multifaceted. (like a stop sign)

The Shaoges have "Chordlength" setting that must be set to the smallest number possible, or the problem is much worse. However, you cannot set it to less than 0.5.

If anyone here has experience with these, and knows how to correct this problem, I'd really appreciate your help.

Thanks,

Richmond
