Hi there,
I’ve made a quick and dirty modification to the sangaboard firmware to be compatible with driving bipolar steppers via an A4899 or equivalent driver. I thought I’d post here in case anyone would like to also utilise bipolar stepper motors in the future.
I haven’t received one yet but boards like these make putting together the hardware quite easy.

cool - we have a collaborator in Paraguay who might be very interested in this - I will let him know you’ve shared modified firmware.

Pin configuration is now setup to work with the arduino uno shield. It’s all been tested using the openflexure connect application. I’ve also changed the code such that release functionality works with the uno cnc board.
