v3.2 Stepper Motor upgrade?

Post by hebbster » Mon Apr 08, 2019 10:11 pm

Anyone upgrading from v3 to v3.2, did you change the stepper motors also? Reading through the instructions it describes both using the old and instructions if you replace them. Looks like the diff is 1.8 degrees vs .9 degrees, so worth changing that also if you're doing the rest?

Thanks Gene & Michael for answering all my questions at MRRF on the upgrade, helped me a lot...

When I updated my v3 to 3.2, I didn't change the motors. It's not a requirement, just a "nice to have". Keep in mind that if you don't change the stepper motors, you'll need to tweak the config.g file for the Duet to reflect the 80steps/mm that the old motors use.

Thanks for the reply!
Guessing they add the ability to have better resolution? Something else?

Smoother motion and slightly improved print quality on very thin layers will smaller diameter nozzles. (at least that's what I've seen on my machine, others may have more to offer on this.)
