Solved Vivedino Troodon Board (non-working w/RRF >=3.1).

@dc42 looks like my build environment was in good enough shape that I could build the latest 3.4-dev checkout -- and I can confirm the issue is resolved. I now get a move out of the motor without errors.

@oliof I tried to find their TMC2660 drivers sold separately, but computer says NO
Would be cool to add them as driver 10+11 to a Duet2. For now we can only use external drivers without SPI on the CONN_LCD pins.

@o_lampe won't these do? https://www.digikey.co.uk/en/products/detail/trinamic-motion-control-gmbh/TMC2660-BOB/8037672

[o_lampe]

@jay_s_uk Theoretically yes, but are they built for 24/7 stress? They aren't exactly cheap either...

[oliof]

@o_lampe you can buy the drivers directly from them, choose the driver as the purchase option on https://www.formbot3d.com/products/troodon-mother-board-and-touch-screen

[oliof]

@o_lampe please note that these are not stepstick compatible drivers! So they won't fit onto a BTT MOT board. You'll need to spin your own bigfoot compatible board or wire them up directly.

@oliof The biggest question is, whether we could add them to the SPI bus or not? It would be nice to have an adapter board on the CONN_LCD connector, like it existst for Maestro and D3Mini.

@oliof I recently got a Troodon v2 and wanted to go beyond RRF 3.0 - which is not possible. Now your post says you had success with 3.4? I am in no means skilled enough to try this but if I understand your post, there is hope that I can - sometimes in the hopeful near future - upgrade to 3.4?

@tak21 you can Just use 3.4 Beta 5?

[tak21]

@pcr oh well ... why should it be so easy (...) THX I will try that

@oliof what does IIRC stand for?

[oliof]

"if I recall correctly"
