My SyilX3 is cutting elipses instead of circles, I am using a file that has worked before and double checked in the simulator, so I assume the problem lies with the machine.
I have attached the file and the xml
Can anyone help?
Thanks
Mike

Afraid the xml and code has not been attached, also if you can post a pic of what you are getting it would help. Could be backlash due to somethng coming loose or possibly loosing steps on an axis or maybe even some scaling on an axis.
