they did change the firmware. i soldered my wires on the under-side of the board where the stepper motor inputs are broken out, so no software changes required. you don't need to worry about silent mode, as the thing is quiet, just adjust the vref pot on the board. you can use 2130's in non-SPI mode too. there is no need to do anything to firmware or the boards if you can solder (this is a big one) and you can just run with the same firmware like usual. you're just effectively swapping the drivers. you don't need the sensor less homing or back efm/skip detection. silent is nice, and it just works.tobias.k3 wrote: ↑Feb 02, 2018 10:28 amSomeone did it with TMC2100 ! Pretty good job:

(I planned something like this with TMC2100 myself. I only have to find time for this.)
It should run wihtout any issue with the Einsy board, especially when you have the 2.5 upgrade. I will report on it as soon as I have the 2.5 upgrade.
someplace. they're under the board and marked. they're tiny pads... you can see them through the holes in this image (they're upsidedown) - EEN,EDIR,EREF would be extruder, then there is X,Y and Z EN, DIR, REF pads too. REF is for the current (it's a pwm signal). you can skip that if you tune them via the pot on the board or use ISP which would need to connect to some other pins on the top of the board.
