Problem with a printer (stepper driver? or motor?)
I have two printers, which are identical. The only difference is that the left one uses 0.9° steppers, and the right one 1.8° steppers.
The one on the left (0.9°) produces crap prints. On the first glance, the print looks like there is a mechanical issue, but the slider move fine and there is not much play. Additionally, the print also looks crappy, if the print speed is 50% slower. Could it be a stepper driver or motor issue?
do post the stepper driver specs.
at what current are you running them?
It's the Duet Wifi on both printers. The print result is crap for the left one with 800-1700 mA per phase.
Please post the stepper motor specifications, also we need to know what VIN voltage you are using and what your microstepping settings are (post the config.g files).
to rule out any mechanical issues you could just move the 0.9 steppers over to that printer.

Well, I use a 24V system for both printers.
The motors of the problem printer should have these specs:
However, I just got the feel that I did not get the type of motor I ordered. My look different in comparison to the Aliexpress offer
I make another post after I exchanged the motors with some from amazon and test again..
Order picture from Ali:
Feel like, my try on 0.9° was really not worth it First batch of motors was total desaster, now I probably got entirely different ones. I bet this is the issue.
measure the phase resistance to confirm.
My Fluke sais I have a phase resistance of A) 1.8-1.9 Ohm and B) 2.0 Ohm.
