I've got my FT-5 r2 coming in the mail, with some TMC2130s from AMZ. I've done a bit of reading and watching videos online, and I see some conflicting info. Does anyone have a picture of their r2 board with 2130 wired up?
I've taken a look over this wiring schematic:
It indicates that the extra SPI wiring isn't necessary because the LCD/SD card doesn't use any extra aux ports because it runs through Exp 1 and Exp 2. If I understand correctly, this indicates that the r2 board can run stealthchop in standalone mode. Therefore, the only changes required, other than replacing the A4988s with TMC2130s is adding the TMC library and making the necessary changes using Arduino.
EDIT: I also recognize that the TMC2130s themselves have to be configured for SPI or standalone via bridging, etc. as described here: https://discuss.toms3d.org/hardware-f6/use-tmc2130-without-spi-in-stealthchop-t406.html
Am I missing anything?
Thanks for your time and info.
