Hello Community,


i was thinking about upgrade my stepper motors of the UMO+ to 0.9° motors.

I heard there are not very expensive and will make the printer much quieter.

Is that true and is it just changing the motors or do I have to change anything in the software?

Would you recommend changing the motors or is there no real advantage apart from the noise?


Thanks for any help!

There is (in theory) an increased precision to be gained by going from 1.6 degree to 0.9 degree steppers... I'm not sure it applies to practice though.
By far the best way of reducing noise on the UMO is by changing the stepper drivers to silent step sticks (I use the TMC 2100 version, and saw there is now a TMC 2130 as well), search for it here on the forums. You mention yours is an UMO+, I'm out of the loop in terms of what electronics board is in that, does it use the UM2 board w. integrated stepper drivers? (if so, you obviously can't change them).

As for changes in firmware if you were to change your stepper motors to 0.9 degree ones, all you have to do is double the steps/mm. for the axis where you changed motors.
You can do this directly on the LCD smart controller if you have one of those...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
