@terencemuscat P.s. - I fixed the connector by pushing it back in, no changes in wiring.

Yesterday I had an ongoing print, and the CAN connector loosened and thus the toolboard was loosing and regaining connection. When I noticed this I paused the process and emergency stopped.
I fixed the connector but now I can get no connection via CAN.
I tried a different tool distribution board to no avail

M122 B10/ B121 gives timeout.

@qdeathstar no

@phaedrux same problem with simplify 3D. I noticed it only happens in complicated surfaces, such as rounds.

@t3p3tony Thankyou!

@terencemuscat In addition, I also reduced the speed and the problem is still there. Pausing points are almost in the same place but not exactly, meaning not a problem from the Gcode.

Hello,

I just finished my toolchanger using duet 3 with hemera toolboards. I installed superslicer (latest stable version) and am facing an issue, pausing during printing. I'm trying to print a benchy and im having blops constantly on one side from all the pausing being done during the print. I decreased the processing limit (g1 per second)from 1000 to 150, and the minimum extrusion length up to 0.05 but results remained the same. It's not minimum layer time as I noticed that sometimes it stops multiple times per layer.

Do you know what maybe is the cause?

Thanks,

Terence

So, i changed the boards and all works perfectly now. Thankyou

Thanks everyone for the detailed explanation. This evening I will replace the board and will give you an update.

Attached is also an image of the toolchanger should it be of interest. Thanks!

@dc42 I'm remembering that during assembly I wired + to - and vice versa by mistake, and I heard a popping noise when I switched it on. However I swapped them and powered back on and everything worked (except steppers). Could it be that I fried the drivers?

I will send a picture later today. If I fried them at least I have another 2 I''m not using.

@terencemuscat maybe @dc42 can help?, I followed your guide in building this. I appreciate all your work. Thankyou very much!

Hello,
I designed and built a toolchanger using Duet 3 having 2 hemeras with toolboards (tool1lc v1.0). Everything is working successfully but im having trouble getting both extruder motors to work. Wiring is checked and looks fine, and prior to this post I also tried to map the z drive to the extruder motors, but they are still not working. I have no errors in DWC, and honestly do not know what might be the cause. However I think its firmware related since I don't think I managed to ruin both extruders during assembly :D.
