Can you test the boards together on a test bench outside of the machine with short cables?

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.

@Panachampu if it shows only a blue LED with everything except CAN and power disconnected, then there is no 5V power on the board (there is a red LED to indicate 5V power). Please email warranty@duet3d.com with a link to this thread.

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

@Panachampu please share your config.g file.

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

@Panachampu if the limit switches are shorting +3.3V or +5V to ground then they are wired incorrectly. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Sensors_endstops.

@Panachampu I don't see anything wrong with your tool heater configuration in config.g. Heater 1 monitor 0 is set to 280C in the M143 H1 command, so it will trigger when that temperature higher than that is reported.

Please check the following:

Does the hot end temperature read sensibly, i.e. room temperature when the hot end is cold, rising when you turn the heater on?
As it heats up, does the temperature reading rise smoothly, or are there spikes in the temperature reading? Look at the temperature graph in DWC to check.
Is the heater fault reported after the desired temperature has been reached and overshot, or earlier than that?

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