I am in the process of setting up and tuning my CNC and I’ve run into a problem I don’t know how to solve.
I went through the axis setup and and used the calculator to figure out my units per step by measuring how far the bit moved and UCCNC calculated the units per step for me.
If I now jog the axis and compare the distance shown on the DRO to the actual movement everything matches. Once I load a g-code file created in Aspire, however, moving my DRO indicated position 10” only moves the cursor in the preview a couple of pixels. I did not realize the mismatch the first time and what should have been a z movement of 0.25” ran the bit straight into the waist board as far as it would go.
Essentially, the movement of my machine does not match up to the distance I expect from my tool path in Aspire.
Any ideas?
