Hello all
I have a small issue with my y-axis and would assume the same with my z-axis as they are both on pulleys

the issue I have is calibration

this only came to light when I tried to cut my dragon out on Sunday night when I tried to cut a distance on my y-axis off 300 mm as that was the size of my model and when I measured it it was 286 mm. at first I thought it was the model software and the scale factor, so I set my spindle to cut at 286 mm and to my surprise my spindle came up short.

well today I have set it to cut/drill three hole in a triangle of 100 mm and it's cut it out at around 95 mm

how do I recalibrate my CNC Machine Mach3 is the software I'm using
