Hmm, I thought that was what the P103 was for (I'm still learning RRF). My thermistor is on the Duex5 "E2_Thermistor3" pins so would I need to add an X-command in that line like this:

M305 S"Bed Heater" P103 X3 R4700 T100000 B4725 ..........; thermistor inside the Keenovo heater

Edit: That fixed it! The bed heater now shows up under + Extra.

Thanks you so much for the help!

The terminals on my Duet seem to be a little loose

What exactly do you mean by this?

Well, you can wiggle them with your finger as if the solder joints aren't solid.

However, I think I have found the issue. I took a Multimeter to the terminals as it was heating and got a consistent voltage so I ruled that out. Happened to have a spare thermistor for a hotend and clamped that to the bed to see if that was the iss. That was it. no issues with heater faults and the graph on the temp panel is smooth as silk.

@p40whk Glad you are making progress. If you are still stuck, post your entire config.g and homing files here.

I'm sorry for the delayed response. Yes you need to add the INT_12V_EN jumper.

As many times as I was on that wiki page I never scrolled down far enough to see the "Connecting 4 wire fans" instructions!" I'll admit I'm a bit embarrassed but thank you for helping me out!

@dc42 thanks to your suggestion about the simple gcode, I think I found the problem.

Apparently if you have G10 in your pause.g (or, I suppose anywhere in your Gcode) and have Z hop defined in M207, after cancelling the print (or, I'd guess, finishing it without unretracting), after starting a new print, z=0 becomes the value of the Z hop height in M207, because it zhops, the print gets cancelled or finishes and never actually zhops down to previous height.

I tested this by uncommenting G10 from my pause.g and the problem disappeared. I also tried setting M207 Z(random number) and after starting a new print, Z=0 is at a height of (random number) and actually you can jog the nozzle into negative numbers after stopping the print...and it goes right to the negative height of M207 Z value.

This seems like a bug in the firmware as Zhop height doesn't get cancelled after the print finishes without unretracting.

Thanks for the report. I've added this to the development list for the next 2.03beta release. Meanwhile you can work around this issue by putting G11 commands in appropriate places, for example in cancel.g and stop.g. Perhaps also in your slicer start GCode and in homeall.g. A G11 command will be ignored unless there is a G10 command that has not already been undone using G11.

Thanks dc42,

I went back and did some troubleshooting and found that I had over crimped the fan connector and broken the wires, my ohm meter showed no continuity.

So I hooked up a fan that I knew was good and it is working. I'll update my firmware and run the fan test again.

Thank you Jacotheron, I'm still setting everything up and haven't tried printing yet so wasn't sure if this would have been an issue or not.

The M571 X coordinates look OK, but I suggest Y150:150 or wherever the middle of the printable Y axis is. Although I think it shouldn't make any difference.
