Stepper driver on Conn LCD for Duet 2 WiFi+DueX5
-
I would like to add two silent Stepper Drivers to connect on Conn LCD. What should I buy to do this and what model of silent Stepper Driver? Do you have any links where I can buy everything I need? Thanks.

@AlexFree Here's the documentation: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external. See the 'Duet 2 WiFi/Ethernet' tab under Connection options.
For drivers, you need some that accept 3.3V signalling. You can't use drivers that need SPI setup. There's some example at the end of the above page: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Motors_connecting_external#examples
Using a cheap 'stepper driver module' breakout board (something like https://www.amazon.co.uk/DollaTek-printer-Stepper-Driver-Expansion/dp/B07HBNYDQR/), you should be able to use any of the 'stepstick' style stepper driver boards that support 'standalone' mode (ie configuring them with jumpers on the PCB itself). I'm not exactly sure which these would be, maybe @jay_s_uk might know? TMC2130 as in the example would seem to work.

@AlexFree the BTT-EXP-MOT might be a better choice https://github.com/bigtreetech/BTT-Expansion-module/blob/master/BTT EXP-MOT/BTT EXP-MOT V1.0User Guide.pdf
