      @mrehorstdmd true <2mm would be massive. but that would also double the material use.
      the prints im doing are just negative molds that get filled with plaster, so they just need to be stable enough to not deform under the weight of the plaster.

      and yes ive also noticed that clean retractions with the bigger nozzles are hard. Specifically the de-retract. when the material rips of the from the rest of the material its just not a clean cut, so when the de-retract comes around its a bit messy. (and the z-hop doesnt help)

      would be interesting to see if one could set a slicing behavior so that when the de-retract happens and the nozzle waits a tiny bit for the mess to be pressed into the below layer and only then continues its journey.

      @imadunatic said in Duet 2 Wifi Active or Passive Cooling:

      did you wire yours in parallel and to the one spare PWM controlled fan connection?

      Yes that's right. Wired in parallel and controlled by temp.

      I would be interested to find out what component needs swapped out. I have some experience soldering, but not sure if it's worth attempting to fix without knowing more first.

      Like I said I was able to get everything working on Fan2 so not a huge concern for me currently.

      If you have a spare heater output (or you use RRF3, which allows you to configure a fan pin as a heater output), you can connect the fan to it. Then use the M307 I parameter for that heater to invert the sense of operation, i.e. the PWM will increase as the temperature rises. Is that what you need?

      Solution!, I had checked literally everything and replaced everything, turns out it was the wire, I set my multimeter to continuity mode and found that there was an internal break in my + wire connecting to the fan, looked intact and was the only other part I hadn't replaced, now that thats gone and a new wire is in place I am up and running with it, so it seems anyway!

      Thanks for the support guys!

      @bearer I don't disagree, just caution that heat sinks need to have good contact to actually sink heat otherwise they can do more harm than good.

      @3mm If you want to try it out, I would be willing to give you a heatsink to do the proper thermal investigation. I have 2 more heatsinks, since they come in a 3 pack.

      I presume you have connected the input of your integrator to the FAN- pin of the FAN0 connector. Did you also connect a pullup resistor between FAN- and +5V?
