I am currently midway to fully automating tedious things like drilling PCB’s. I am a IVEX product user but would like to incorporate drill file support in my application to extend support to those of you using other PCB editors. If willing please respond to this post with a drill file from your PCB CAD.
With my use of 2 14.7 RPM ECM Moror Co gearheads and 2 Motorboard V3 and an Uno as the controller I am attaining a positioning accuracy of .5mil/step. along with the program is a modified Stepper Library. The Stepper mod is a return value from the step method indicating whether a step took place or not. The second motor deck must be modified to remap its pins to available pins left on the Arduino. Although some would dispute me, its not fast and I don’t need it fast…as long as I am not having to hit those tine pads with a tiny drill bit with my waining eyesight, it can take all day to run a job. Speed gives rise to positioning accuracy loss and pole slip in the syncronous motors.
