Feature Requests / loosing steps - captive encoder
« on: May 19, 2012, 01:12:03 AM »
Hi
I'm new here
I'm having a Rotwerk mill (sieg x2) - I'm not having any problems but i found this item at CNC4PC : captive encoder for nema23/34 steppermotors
how do I implement the encoder to read the steps - give feedback to mach3 - and make mach3 to do the "adjustment" of the stepper movement?
example: mach3 moves the steppermotor 10mm => 2000 steps, the stepper "looses" 3 steps so fact is the spindle only moves 9,985mm
IDEA: the captive encoder give feedback to mach3 and moves the spindle additional 3 steps (also have to work if the stepper moves too many steps!!!)
How do I do that?
