but you can drive a normal
two-phase stepper in continuous, non-stepping mode. In this mode they are
just like servomotors. Then they attach a rotary encoder. So
step-skipping is not going to happen as they don't step.
Stepperonline sells these all setup and ready to go as drop-in replacements
for normal steppers. The servo-loop is closed inside the driver
electronics so the computer just sees the usual sep/dir interface.
I am fam with that, I'm already using 4 of the nema 23 3 phase versions
which are lots more efficient power wise, but didn't know it was
available in nema 17's. I've asked for a quote for the bigger one in
dual shaft. Thank you, Chris. Take care & stay well.
Cheers, Gene Heskett.
