My SmoothieBoard is on the way and I'm trying to understand how to configure it for my three axis CNC mill. I am reading the CNC Mill Guide which is very well written. I'm understanding most of what's there.
The problem I have is how to set up Smoothie for English inch units. For instance there is the parameter alpha_steps_per_mm. Is there a alpha_steps_per_in for inches? If not do I put the steps/inch in this field and when Smoothie gets a G20 it will just use the alpha_steps_per_mm field value but expect it to be steps per inch? Or does this value need to be converted from steps/inch to steps/mm?
This has me very confused. If there are other metric fields are there english inch versions of the field or conversions necessary?
Thanks for helping this newbee.
