  Ok divide  200 ~ (the 'steps-per' that is set on the axis in motor tuning) by the cut measurement minus the cutter measurement(Dia 3mm as the software is running in metric mode 0r 1/8" if you require brain drain ), and then multiply by the measurement you told it to cut which was 100mm..

		Are we actually sure these are metric screws? did they kick you a machine built for our American cousins and give you one with imperial screws?

  Im not sure what they are but something is not right but then when its cutting a circle we can get him to look a bit deeper into it.. I do however suspect you may be correct at least in some part..
