Ok, thanks. Here I was trying to mill a pocket. Pocket start/corner is located X20 Y20 from Zero and pocket dimension is also 20x20mm.
But after milling, the left and buttom side of my square pocket is about X21 Y21 from Zero when I messure it with a ruller. I didnt messure exactly, because its very clear that its not where it shoul be.
The pocket has the right dimensions.
Im sure its my fault, but I dont know where to find it.
The code is generated with Vcarvepro. I dont know if its changing when loaded to Mach with Machs offsets and fixtures.
I mean I have never changed any offsets and fixtures, because Im not sure how to use them - maybe here something is wrong.
I was milling like this for 2 years, but first now, when I had a piece of material with exact dimensions I realized that something is wrong. I was always cutting things out, so I didnt see it.
