I just used standard Home Depot conduit that was definitely not smooth at the beginning and I never had any problems. Now the zinc plating is worn off on three sides of all my tubes by use. All my felt time pen plots have smooth lines, even when attached poorly with duct tape.

I’m also using DRV8825s with 1/32 microsteps. My steppers are 480m Nm.
