Toolboard 1LC does not work

asimitabi

Hello guys!

I just installed a 1LC V1.3 toolboard to my Duet 3 Mini 5+ without a tool distribution board.
I am powering it a VIN (24V) and the CAN is connected as its shown in the documentary and I soldered the 120R resistor (I bridged it on the backside of the board with solder).
I placed the G4 S2 command in the config.g file.
When I send M115 B121 (I also tried M115 B10) there is no reaction.
Also only the blue LED is on.

I really dont know what could be wrong or why it is not working.

Can anyone help me or give me some tips I can try?

Thanks and best regards!

@asimitabi you could install this plugin, this would show if it's being detected https://plugins.duet3d.com/plugins/DWC-CAN-Manager.html
But as you have no red light (blinking slow or fast) points to another problem.
I suggest trying a factory reset https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Toolboard_1LC#factory-reset

@jay_s_uk thanks! Already tried to do the factory reset but nothing changes.

I pressed the two buttons and started the board. But its like the other times because just the blue led is on.

Okay sorry guys I just found the problem even though I dont know how this could be.

It seems like the grounding point was not strong enough. I measured the VIN and it was only around 2-3V. So I used another ground point and not it works.
The old ground point was directly connected to the ground of the plug that goes into the printer. Now I connected it to the ground coming out of the power supply.

I did not knew that there could be any difference?
I mean the ground point from the plug also goes into the power supply.

But now it works, thank you anyways @jay_s_uk !
