If this is a feature already please excuse the request. Can a mm/inches rulers appear on screen when displaying cuts and sled location? My apologies if I have requested the moon but thought it could be helpful in managing material and test cuts.
That is an excellent suggestion. Do you have an example of a program which does what you are looking for well?
Inkscape has rulers that I like. Their’s are relative to your page so they would reflect a positive and negative direction. I would propose in Ground Control that the rulers would display in a positive or negative based upon the current location of the “defined home” to help estimate size of material that is necessary for all cuts. Hope my explanation makes sense.
