Sorry for the bad video… :wink:

Cool. Looks like it’s working. Those are pretty beefy stepper drivers for that setup. I would guess that if you’re aiming for power, you would be better off moving to a ballscrew and away from timing belts and the stepper size wouldn’t matter very much because you’d get a mechanical advantage from the ballscrew but also a precision advantage.

Yes indeed. Those stepper drivers are pretty over sized. But i got them from china for 5 bucks each. So no problem.

I still have three spare PCBs (only the PCB, not the parts) lying around… If anyone wants one i can send it over for rounded up postage fees

After messing with every darn belt configuration we now do nothing but ballscrews for the wood and metal CNC machines we are building. I’d still like a headless TinyG because there are a ton of mchines with drivers out there that just need new brains.

@Steve_Anken : That’s one of the reasons i built this version. Maybe we could colloborate on this one.
