I am correcting the problem with pushing my steppers out of their "comfort range" and losing steps.
But I have research funds coming up again and am wondering about encoders (the reason I got dual shaft steppers). I am increasing the moment of inertia on my axises to help decrease movement per cut , and smoothing gibs, considering a linear bearing set up, but that introduces a new set of problems. But I am having personal issues trusting 6 hour run times. The goal is extreme precision, not speed persay.
So an intermediary controller between mach3 communicating with encoders and sending step information would be a simple task with my previous experience and I have all the hardware on hand except the encoders. Anyone see a good deal out there?
To make the coding easier and price lower 200 ppr absolutes would be perfect, or any factor of 200 please (would really make my algorithms easier).
Thanks everyone, sorry been so quiet, when I lack funds and am not machining, reading of others awesome is hard.
Going with incremental encoders I could run a gcode preprocessor to insert code modules that zero out the head position at given command increments.. that should be a very good solution for extended run accuracies...
Koyo Series E2 decent? 50.00 each I am still confused how I will handle a stop right at a ttl channel hig/low change, hoping the 1.8 degree movement will keep my encoders well withing their high/low settings wave
