[Lab] seeking feedback on steppers and spindle for my DIY CNC router

always learning...

I had not known to look for a speed sensor, thanks for pointing it out.
I'll do some more research/shopping today.

I've noticed that some ER8 collet models are showing up in my searches.
I'll have to watch for that too.

I'm not worried about a long shipping delay, I'm sure it will arrive before
I get my z-axis built :-)

thank you for the information,
Olaf
