Calibrate x and y axis k40 with Cohesion3d controller

Machine: K40 original Nano board, upgraded to C3D
Board: C3D
Firmware: “I have a new board and I’m using whatever it came with”

Problem/ Question: _Created a test box in Lightburn 100 mm by 100 mm and it’s printing 105.2 by 105.5 mm.

You’ll need to scale the alpha_steps_per_mm and beta_steps_per_mm values in the config file appropriately. Try 149.381 for the axis measuring 105.2mm and 148.908 for the axis measuring 105.5mm, respectively.

I scaled the 157.575 default value down by 5.2% and 5.5% to arrive at those values. You may need to play around with it some more to get it spot on, but this will at the very least get you a good starting point.
