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 !
