Quoteo_lampe Is it PWM control you are using to regulate the brushed motors? BTW: Have you seen the video of my balancing bot with BLDC motors? It goes back and forth and stands still, just like we need for an extruder. But these gimbal motors are pretty weak. Yep pretty sure every diy motor driver (accept stepper drivers) ive seen for printers uses pwm! Cool robot.by warbunniex - Developers
Quoteo_lampe I hear you... The only way to make this last is with brushless motors. Low kV pancake brushless outrunners to be exact. Most of the RC-brushless stuff has no hall-position sensors. But equipped with sensors, there are no small enough controllers. My design doesn't need the encoder to be attached to the motor directly. So that isn't an issue. Are there no diy brushless drivers?

You mentioned you were having trouble with the firmware side of things. Have you seen this yet? I wanna get this stuff going! I've finished up the parts for my micro extruder 2 and I'm hoping for something with more momentum than the tarroco drivers. Here's the first version of the micro extruder in action: https://www.youtube.com/watch?v=hAm5rLlzdFg It worked okay but the encoder didn't haby warbunniex - Developers
