asking again, Duet 3 6hc running Klipper?

oliof

@gnydick Klipper's CAN implementation does not hold water to RRF's CAN-FD one. Most klipper people I know use USB to connect their secondary MCUs and toolboards, which seems to be better supported on klipper (see https://os.ratrig.com/blog/no-you-dont-want-to-use-can/ for a rant against CAN on klipper). You won't be able to use the 1LC board since the efforts to port klipper to it died from lack of interest.

@oliof yeah, i learned that the hard way. I got my entire machine converted, sans the tool boards, and then came the pain. converted it all back.

I have just been told that development of klipper for the 1LC toolboards has been resumed. So lets see where that goes. People would still need to add a separate accelerometer since klipper does not support LIS3DH ... (edit https://github.com/Klipper3d/klipper/pull/6009/ -- currently misses any documentation about how to get it flashed etc.)

@Herve_Smith I would prefer a constructive and friendly tone in this forum. Especially since you seem to agree that CAN on Klipper is not a good idea.

Trust me, your post does reflect badly on this community.

@Herve_Smith And a good day to you you, too!

@Herve_Smith the issue with your post is not that you believe the problems with klipper's can bus usage are due to the implementation, rather than the underlying architecture. The issue is the personal attacks: "raving idiot" , along with the overly aggressive tone.

As @oliof has already pointed out, there is no place on this forum for this behaviour. Please use a constructive and friendly tone, even when you disagree with an opinion.

@oliof I posted a script to flash 1LC boards using OpenOCD and a Pi elsewhere on the forum.

@Wulfsta this one I presume https://forum.duet3d.com/topic/29857/raspberry-pi-4-to-toolboard-1lc-with-openocd/14?_=1682879698520

@oliof yeah, that’s it. Huge pain to figure that out. I’ll add docs to klipper eventually, but it’s not my priority at the moment. Meanwhile it should be easy enough to figure out by looking at the schematics.
