  Summarising the above, there are two ways: If you want to control the chamber temperature using a heater and thermistor, configure it using M141 and it will show up in DWC as normal (but not yet in PanelDue). If you don't want to control a heater but you just want to display the chamber temperature, create a named virtual heater as in the post by @bearer.

  Thanks! I'll make a separate thread about that after seeing what I can learn about how the old electronics drive them. But they are high resistance and low power motors, which i think i read something about being an issue. Apart from 25 ohms per coil I don't have any specs yet, and no markings on motors.

  There are different default M307 parameters for H0 and for the other heaters, because H0 is assumed to be the bed heater. So you will need to change the M307 H1 parameters to suit a bed heater, and the M307 H0 parameters to suit an extruder heater. To find the defaults, boot up your Duet with the SD card removed, then send M307 H0 via USB or PanelDue, followed by M307 H1.

  I went to the Duet from AM8 too. For the wiring, I re crimped all the connectors with the supplied crimps but I just sat and took my time and matched all the wires up one connector at a time, was easy to follow the wiring diagram for the Duet maestro with everything seeming easy to work out where it goes.

  Unless your hot end heaters are unusually powerful, I suggest a 7.5A fuse rather than 10A. It certainly won't protect the fan mosfets if you get a shorted fan, but it might protect the heater mosfets.

  Do you know what the VIN coupler shorted to? As your Duet is responding apparently normally, I think it's most unlikely that it has a fault that would damage a connected DueX5.

  I had an issue with one of my V6 hotend thermistors where it would get wacky at times....turns out the wires were failing right at the thermistor cartridge and I could make it happen by lightly touching the wires and see it jump. I would start by checking the thermistor out.

  @dc42 said in Heating fault on heater 1, temperature excursion exceeded 15.0°C: @aimrabbit said in Heating fault on heater 1, temperature excursion exceeded 15.0°C: @dc42 oh ok I think than I have also to send back the chimera that i bought Thanks a lot I order it right now Ask E3D or their distributor if you can just swap the heater cartridge they supplied with the Chimera for a 24V one. There are no words to describe how thankful I'm for your hint. I make some research and found that "2x30W Heater cartridges (12V/24V)" I think that means it supports both so i can change the hot end and kick that tronxy shit away. Hopefully I get my first print after that.

  Saw a similar answer on a topic for a solenoid valve. But since I'm not expert in eletriconics better be safe! Will give a try to tool changing with this magnet. Thank you!

  @pieter said in PNP Z-probe connections....: @dc42 Thanks, i've installed 2 new resistors, think i missed me on the color code before, now i'm using 1 of 10K and 1 of 30K, works perfectly, got 3 volts when triggered and 0 when not triggered Sounds good!

  I will add my 2 cents on the matter. I have successfully connected this kind of an SD slot board to the DUET 2 "CONN_SD" port The board has both 3.3V and 5V input, I went with 3.3V. Connecting it is really rather easy, get the DUET pinout diagram and make connections from DUET "CONN_SD" to the board, GND to GND, CS to CS, MISO to MISO and so on. I used an ethernet solid core cable and in total its maybe around 1m long. So far I have two over 8h long prints behind me and so far with no issues.

  @snoozer said in Choosing a suitable power supply: I split the mount. Intend to be able to manually change between hotends and also service it easy. I did a rework of this mount, in Fusion 360: E3D V6 Hinged Extruder Bracket & Clamp for my little Monoprice Select v2. It's pretty kludgy so I didn't post my rework, but I have all the wires on plugs and can change the v6 clone on it in about 30 seconds. (Went with genuine v6 Gold for my CR-10S) Kinda cool to have a hinge. @pedromelim - Good luck with your project, keep us posted!

  I did have the fuse blow, when I first got the board and I wasn't paying attention to how I was connecting everything, so the fuse was the first thing that I checked. I have version 2.0xx of the duet wifi. Since it's just the part cooling fan connector that's not working, I think I might patch the part cooling fan into the always on fan connector for now to stay operational while I wait for a new mosfet. Of course I get this failure right after I accept an order for printing... Also I had a serious geek out watching your youtube video about the mass-cancellation gantry that you made for your beast of a printer. I have serious machine envoy.

  Thanks for reply. So it appears to be best case 8mA source for logic 1 and 15mA sink for logic 0.
