HELP in BIG SIZE 3D with STM32 & IHM03A1

Hello Guys,

We are development a 3D printer (Big size) with a old cartesian 3D robot (stepper motor comsuption around 8 AMPS) and we are trying to use STM32 driver IHM03A1 (10 Amps and we can move the machine withot firmware). We don´t know if is possible that marlin manage the STM32 with these kind of driver (without ramps). Is part of our final degree, in the past the 3D was working with powelolu (GermanRepRap) but the drivers was broken and no is possible to buy it.

Thanks you so much.

Best regards from Spain.

... if the stepper drivers have STEP+DIR with 5V signal level, then yo can drive them direct from the Arduino pins (if Arduino with 5V I/O pins) ... otherwise you have to use level-changer to higher voltage inputs.

I'm controlling "industrial" 24V-signal-level machines with ArduinoDue (3.3V I/O signals) and Marlin4Due
