Steppers with Encoder using parport was created by reedmachine
I hope I put this post in the prefered location. But I wanted to show my configs for using a 3 axis stepper machine with encoder feed back through parrel port in "X" mode for others. The primary objective was to only fault (stop machine) if ferror is reached. I speractally get missed steps from iether retracting the drill from holes or just the cutter getting dull on profile cuts & one of the axis gets out of time, so I would baby sit the machine during cycle. Now I feel confident to walk away.
I am running this on a b-port machine useing 1200oz./in. motors w/ 512 ppr encoder & simple break out board from probotix. The only tuning was P so it reaches commanded postion within reason at max vel. I know its not a servo, but I started with stepper and for cost of encoder & cables, it works for me.
