Rotary settings/steps

OMTech K40 with C3D board

Whatever came on the C3D board

I have a rotary set up but the steps appear off. It is a 2 phase 4 wire stepper motor similar to the one sold here. I have it plugged in to the A port.

I do not see how to change the steps in Lightburn or make any other changes. When I try to make a simple shape, it is stretched out way to long. I am confused on how to change the steps or if I need to change something on the board.

you need to edit the config file on the SD card inserted in the board. This article is specific to the C3D rotary, but the same steps will apply to your rotary as well. Adjust as needed:
