Whenever it is running at a higher feed rate, 20mm/s , doc 4mm in mdf the circles become really jerky? Is this typical?

I think I found the issue, I had arcs enabled in Estlcam. Does the latest version support arcs?

Edit:
Turning them off didn’t fix it but turning the jerk from 1 to 2 on the x and y did?

I just commented on your other similar topic. The jerky circles may be related to a bug that is fixed in the latest release of the V1 firmware.
