@dc42 Hello, when I tell DWC to heat up the hotend, the heater turns on and two seconds after that it shows the fail

@Panachampu
I also have a problem with the limit switches. They make short circuit

@dc42
Here it is all the firmware link text

@dc42
It now works, I connected the power from the 24V power source and it now works, thanks to everyone. I have another question, the hotend doesn’t work, after clicking on dwc to activate it, it shows an error: Heater 1 fault: monitor 0 was triggered

@Phaedrux
I rewired all the can bus thing, and disconnected anything else from the two boards, and nothing happened, it only shows a blue VIN led. I reinstalled the firmware, but one thing, how I have to install the firmware? I installed it with the SD card which has all the files of the configurator, excepting the .json, including the 3 .bin, I think that the 1LC is not doing nothing, it doesn’t flash.

Thanks for your response and sorry for the delay.
Back to the machine, I’ve welded the jumper of the 120r resistor as it goes in the documentation, and it keeps non comunicating. It only shows a blue led, nothing more. The 24V VIN comes from the 6HC, and the firmware I think is of the same version, it is from the configurator tollo, which I think uses the same version in the boards no? I’m sending you photos of the connections.
Thanks,
Gabriel.

Hello, I have wired all the 1100x1100x2000mm 3d printer, I need to wire the bed and the endstops. I connected to the printer via DWC, and the interface doesn´t detect any board with M122 B121. I also tried with M122 B10, but it always says this: "Error: M122: Response timeout: CAN addr 121, req type 6024, RID=18" I think it can be a problem in the Can Bus wire, but I tried all, I changed the red wire with the black wire, and nothing happened, I switched it again and nothing happened, and I´m trying to make the machine work, but I can´t. If any of you know what´s happening, please help me, I will be happy of doing any test or any comprobation
Much thanks
