Good Evening,
I think I can gladly report that this issue is solved.
As suggested by dc42..
@dc42 said in Toolboard 1LC V1.2 will not connect:
Perhaps the tool board is not at address 121. If you send M409 K"boards" does the response list just board 0 (the Duet main board) or does it list the tool board too?
Well it did recognise the board and its address was 20.
So looking back through the documentation and specifically,
Set the CAN address
Send command M115 B# to verify that the main board can communicate with the Toolboard, where # is the original CAN address (normally 121)
Send command M952 B# A## where ## is the new address you want to use. We suggest you use addresses starting at 20 for Toolboards. So for the first Toolboard, if your new CAN board was at address 121, send M952 B121 A20.
Power the system down and up again, or send M999 B121. This will cause the Toolboard to restart with the new address.
Send command M122 B20 (or whatever address you chose) to verify that you can communicate with the Toolboard at its new address
You can now power up the next Toolboard and commission it in the same way, choosing a different CAN address for it.
Thinking back, I would have followed the documentation and changed the address to 20 and then promptly forgot that I had done it.
This led to countless hours of trying to sort the problem out, the cost of another toolboard and taking up others time to try and solve a problem of my own making!
Anyway, thanks to dc42 and jay-s-uk for the help and please dont curse me too much!
