UM! stepper motor voltage

[onkelgeorg 36]

Hi all,

I want to replace My UM1 Original extruder with chopmeisters H3 extruder. In order to avoid any trouble with the small gear on the motor I want to buy a NEMA 17 motor and replace it too.

So my question is: Which voltage and current values are required for a proper replacement motor?

Any help is highly appreciated.

Cheers,

Joerg

Voltage rating does not matter as long as it's lower then 19V (it's current regulated)

Current value, you want to be around 1.2A

This would work fine:

great, thank you.

Especially the link to watterott is helpful as I already wanted to order a few things there
