Hello,

yes i mean the i3 pro B
The Stepper for the extruder is the only motor with a type sign the others don't have this.
primary i will know how much Ampere or Milliampere they max. tolerate ?

The link is to the data sheet spec. This motor is 1.5A max. I have mine set to 1.2A and it is working great.

this is clear and the extruder works so far
i have changed the stepper driver from A4988 to DRV 8825 and now i will calibrate the new driver for the other 4 steppers

it is 42shd0034-20b with 1 Amp. https://www.geeetech.com/hybrid-stepper ... -1011.html
