Non Duet Hardware with RRF ?

@dc42 the SB2040 is a different implementation than the board you have seen. It may well require hardware changes before it would be suitable. for example it has a SIT1040TK as a CAN transceiver

@Herve_Smith Theres no current plans to support CAN 2.0. As dc42 mentioned, they are working on bring CAN-FD to RP2040 based toolboards.
With the teamgloomy port, none of the STM32F4 MCU's support CAN-FD. Only the STM32H7 MCU's do.
At the moment, the supported list of boards to connect over CAN-FD is- Duet 3 6HC (in expansion board mode - M954)
- Duet 3 6XD (in expansion board mode - M954)
- Duet 3 Mini 5+ (in expansion board mode - M954)
- Fysetc Big Dipper (in expansion board mode - M954)
- Another STM32H723 board (in expansion board mode - M954)
- Another STM32H743 board (in expansion board mode - M954)
- Duet 3 1XD
- Duet 3 3HC
- Duet 3 1HCL
- Duet 3 1LC
- Duet 3 Distribution Board
- Sammy-C21
The only toolboards are the Duet 3 1LC. Fysetc has cloned them but they currently have no stock of the MCU to manufacture any more

@Herve_Smith i've mounted my toolboard to the back of the X carriage. Theres enough room for it not to come into contact with the z chain.

@Herve_Smith feel free to swap over to klipper then.
no idea what the eta will be on RP2040 toolboard support -

@Herve_Smith I went with the dirtybird toolhead and let the 1lc hang out there in all its glory lol.
-
@Herve_Smith that's nice looking. I need to revise my toolhead location as I plan on switching to tap and I won't have the rear mounting position available any more.
-
@jay_s_uk tap seems to be pretty good from what I hear. Just not sure if I'll go for it yet.
-
@R4ffers gives me something to do.
at least it'll work nicely with RRF too -
@jay_s_uk aye, let me know how get on especially with your light weight X rail. I've got one on order
-
@R4ffers the lightweight x rail is great. i temporarily had a carbon fibre one but that was awful. worth the investment

@Herve_Smith said in Non Duet Hardware with RRF ?:
I just drew up a modified version of the "tap" that is lighter, uses less hardware and uses a pair of cross roller guides instead of a linear rail for stability
Cross roller guides? Do you have a link to those?

@Herve_Smith thanks. I've ordered a set in preparation

@Herve_Smith awesome thanks for this, just ordered a set
