hi guys, struggling with a carving issue and not sure where to go form here. I have a basic shape 170mm high which is same as the piece of wood. i am trying to cut a circle 150mm exactly in the y axis centre from top to bottom. the design svg is spot on and the wood is measured correctly. I set my probe and use a bit to get to the wood at 0,0 but when i cut with my 1/8 bit the circle keeps coming out about 1 to 2 mm higher at the bottom than the top so is not centred. ive checked everything i s squeare and all the other usual bits and just cant work out what is wrong. any help aooreciated.
have you calibrated your steps per mm, for each axis?
sorry, not sure how to do that, or what you mean by that
