Just one question John, is that encoder optical, or hall effect?
Optical is real time, hall effect is not.

On a past life before I started using servos I had attached encoders to my
steppers to stop the machine when steps were missed. I used us digital
encoders that came with adhesive backed mounts from the factory. They
worked swimmingly. I still have one in the "spare parts" room. The encoder
is still securely attached over 10 years later. "double sided tape"
essentially woked very well.

[EXTERNAL EMAIL] Be sure links are safe.
You have such a large flat surface area there. Design an encoder mount
plate of similar size where the end result is also has a flat surface.
Rough and clean the back of the motor up, then use a decent polyurethane
adhesive to bond it on. During the setup you could use a jig to keep it
concentric with the shaft.
Design it in such a way that you can still replace the encoder if need
be.

I want to add an encoder onto the back of this stepper motor. I can
install either a US Digital or a CUI since both mounting flanges can
extend out near the edges of the back mounting plate.
Is there any reason I can't clamp the motor in a vice and pop in two
holes
and tap them with a bottom tap at the spacing of the mounting flange?
