@JRCL the medium-current (i.e. fan) outputs on Duet 2 are rated 1A but can handle 1.5A for short periods e.g. when a fan is starting up. However, the entire fan power circuit (2 always-on output and two switched outputs) shares the fuse, which is normally 1A. You can increase it to 2A or even 3A if you are sure that the individual outputs are not overloaded.

Duet 2 boards include flyback diodes on the fan outputs but not on the heater outputs.

@droftarts this was what I needed! I had been using the table above that, that says PCB Pinout, but I'm now realizing it's for the BL Touch's pins not the boards. Thanks!

@JRCL If you need something for ethernet then there is also this option, which would allow you define your own notification rules/endpoints etc. It uses node-red and works off the basis of polling the board, and provides built in nodes to define events based off the object model data.

@chrishamm Thank you! I didn't realize you could literally use an asterisk. I thought it was a placeholder

@JRCL the series resistor I referred to is your potentiometer.

@JRCL just for reference it's detailed here under permanent limitations https://docs.duet3d.com/en/User_manual/RepRapFirmware/CAN_limitations

@droftarts There it is! With this change, the stepper finally started working. If I wire to + set then R0 works and if I wire to - R1 is needed.

@dc42 the internal wire swap was it! Once I cut it open and swapped CANL and CANH they synced. Thank you much

Cooling is a great thought that hadn't crossed my mind. I'll be sure to poke at that and my temps/fans, appreciate the insight!

Thanks for the quick responses! Looking forward to trying out this configuration

@JRCL a CoreXZ would normally have a moving bed or moving gantry Y axis, so the same technique would be used as for a bed slinger.

@dc42 no M575 in my config, but here is the whole thing in case

@JRCL the best option for driving relays from OUT pins would be to use 12V or 24V bare relays instead of a 5V relay board.

@JRCL @droftarts Other thermistors had no problems with the correct Y variable, so I likely have a broken or spliced thermistor. Time for a little tear-up!

@Phaedrux this actually ended up fixing it. The error message went away once the tool definition was correct.

Ended up switching to a Duet 3 for more connections anyway, never figured this one out
