Higher voltages #3

Open MortarArt opened 2 years ago

Apologies if this is not the correct way to ask a question of the project team. What modifications would be required to allow this to be used with a higher voltage power supply & a larger stepper motor, like a Nema34?

Neumi commented 2 years ago

Hey! Thanks for the issue. Currently, I use a DD4012SA and the TMC2208. So the input voltage limit is currently at around 36V, but for safety kept at 30V. When updated to TMC2209, the max voltage will drop to 29V. What voltage do you need?

For running a Nema 34 stepper you'll need a tmc5160 with 48v, minimum...

As mzilly02 pointed out, 48v is the starting point really for a nema34. Though, the higher the better for high speed applications. I'm only currently looking at low speed work, so 48v is what I'm aiming at since it's a little safer.

Coincidentally, 48v is the most used PoE (#2) voltage...
