Hello, Changed my controller to DDCSV3.1 4axis
All is ok, but inner holes are smaller than expected after machining(for example Ф7.4 instead Ф8) - i tryed a different posts and programs.
Where can be problem?
Other dimensions looks acceptable now
This is caused because your steps/mm are incorrect which is causing your whole part to be off actually but your only seeing it on the circles due to this being amplified due to the circle and how the code makes it up. Try and jog your machine 1 inch and measuring the distance traveled with a gauge. If i were to guess your machine will travel just under 1 inch. Its very typical when people round numbers during this calc.
