Hello, first post here and looking for some advise. I have Iconic 6. I was cutting a round profile in Cherry last evening on a project and was using 1/4'' Endmill. 15,000 RPM and a feed rate of 40 IPM. .08'' per cut. Total depth was .825. When the operation was complete and I removed tabs, The outside of the circle had a lot of erratic tooling marks. It was seemed to be when the X and Y drives were changing directions it was not a smooth transition. These marks are about .015 to. 020 deep and are consistent to each pass that it made. Do I have drive issues or is there something loose? It happened at least 4 places in a 10'' Circle. Any help or advise would be greatly appreciated.

Welcome to the forum!
The first thing I would try is to set the simulation preview on a high resolution. Run the simulation. Then zoom on real close on the trouble spots. If you see the same problem there's something wrong with your drawing. If the simulation is smooth, there's something wrong with your machine.
Also, did the irregularities appear where the tabs were?
...That was step one...

Thanks for the input, I will look at the simulation as suggested. The spots of concern do not seem to be in conjunction with the tabs. They are random and some are about 1/2'' to 3/4'' in between and at erratic spacing around the circumference. Then they are areas that are smooth.
Thanks

Lateral divots at the quarter points (1:30, 4:30, 7:30 & 10:30 clock positions) of a circle is usually an indication of some mechanical looseness. Check the motor couplers, ballnut mounts, etc. One of the other motors change direction at the 3, 6 9 & 12 positions
