    Sorry have to double post it since i posted on E3 section by accident.
    What is the stepper motor torque specs for original robo3d R1 ?
    Also what kind of controllers are used ? They seem to work different from any that i have tried and i like it and want to buy some more.

    I also need to know model number and what angle and phase and what controbutes to higher torque, amps or degree or what ?

    I am trying to find smallers most torqy motor i can get. E3D 32mm motor was garbage.

    OH great, i just realized i posted in the wrong place again.
    Can someone move it ?
    Thanks !

    The extruder stepper and all of the other steppers in the R1/R1+ are step angle of 1.8 degrees (200 steps/rotation) and roughly 30 nm of torque. Higher torque is as much a by-product of the motor construction (windings) as anything but a higher current is usually an indicator. There will be torque specs for the motors. This is what I have used and they are more than adequate for anything in the R1 series:

    Bear in mind for those machines you wan the 4 wire steppers, not the 6 wire.

    If you mean the stepper drivers the stock ones are Pololu A4988 : https://smile.amazon.com/gp/product/B00MQR93QC

    (link is example, not a suggested seller)

    If you mean the other electronics -- it is an Arduino Mega 2560 with a RAMPS 1.4 driver card. The R1+ used a slightly customized one (thanks Robo!) it is electrically identical, but the connectors are different and moved. There is a thread by @Geof that shows how to replace that with a standard RAMPS 1.4
