Steppers & Encoders

[widgitmaster]

I have been told that stepper motors with encoders are better and more accurate than steppers alone. I have been searching with Google to learn more, and stumbled across this link:

My question now is how many pulses per revolution do I need, and does Mach2 software support the encoders in the link above?

My stepper motors are 200/rev, 1.8 deg/step

Mach2 won't support any encoders with steppers. There is an add-on encoder board for Mach3 that will be available soon, but it won't make them more accurate. It will just pause the machine if there is a position error.

Thank you for your fast reply!
You saved me from spending another $150 for something I can't use!

This learning curve can get expensive!
