Vivedino Troodon Board (non-working w/RRF >=3.1).
-
@dc42 I do have a Duet2Wifi with a blown driver (E0, so driver 3 IIRC). I never upgraded that board to RRF3, and had packed it away to send for repairs. I hadnot gotten around to sending this board out, so I was able to do a comparison with the Troodon board.
In the simple test bench setup with one stepper connected to driver 0 (X), this board does not exhibit the same failure mode as the Troodon board. In fact, it just works without any complaints.
Of course this might be because there actually are traces and resistors on the board for this driver (or the driver is only partially broken instead of completely missing), so the behavior of the overall board could very well be different.
Since I noticed you got the change landed already, I'll see that I get my build environment up and running again for a (hopefully) quick build and feedback cycle.

@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. -
-
@jay_s_uk Theoretically yes, but are they built for 24/7 stress? They aren't exactly cheap either...
-
@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
-
@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?
-
@pcr oh well ... why should it be so easy (...) THX I will try that
-
@oliof what does IIRC stand for?
-
"if I recall correctly"
-
@oliof Thank you sir......:)
