Hey all,
This is my first post ????

I have a problem with my cnc machine
It's a 6040 with servo motors and a cooling option with a bath.

Trying to mill a part but all of them have a problem with the dimensions of I mill a square 50*50mm it will be 50.2*50.6
And if I do a circle of D12mm or will be 12.2 on x axis and 12.6 on y axis

Did calibrate the steps using an indicator and have 0.02mm error

Did cut a 90deg side in wood and it looks ok

What can be the problem?
And where I can find more info about the machine and how to calibrate

Thank you very much!
