TMC2130 & Megatronics 3

Post by syd » Tue Jun 05, 2018 12:31 am

Hello,

i have an Megatronics board on my "old" Multec printer. And now i want to upgrade also to the TMC2130 drivers.
I think the pinout is a bit different then the ramps (see picture) Does anyone know on which Dxx the driver pins connect?

Thanks,

Syd

You Need 3 SPI Pins shared for all 2130 and a dedicated CS Pin per Driver. with the latest Marlin bugfix branch you are even not bound to use the Hardware SPI. But looking on your Board I would connect SPI to MOSI(D51) MISO (D50) and SCK (D52) so this would be compatible with Marlin 1.1.8 for example. For the CS Pins you can select whatever spare D Pins you have and configure them in Firmware AUX 3 D46 - D49 would be candidates
