Hello friends. I have installed the Auxiliary Heating Module as per the directions that came with it. I have modified my printer.cfg file to include chamber_hot.cfg. The heater works to heat things up, and I successfully did an ABS print with it.
I have a stock system with no custom macros.
Since that time, now when I go to do a print using the heater after it lays down the purge lines it cancels the print saying “The value ‘fan3’ is not valid for FAN”
I don’t see any references to fan3 in
chamber_hot.cfg
macro.cfg
printer.cfg
Check your start g-code in your slicer.
Open a g-code file in notepad and search for fan3
If you can’t sort it out download klippy.log from your printer, zip it, and upload here.
SOLVED: Turns out it was an OrcaSlicer issue. If you turn on Active Air Filtration, OrcaSlicer expects whatever is going to do that is plugged into whatever fan3 is. On the Sovol Zero fan3 is used for something else and nothing is plugged into it. Thanks to folks in the Sovol Discord for helping me with it.
I disabled it and am back to printing ABS.
Yeah, I added a Nevermore chamber filter to my Zero, and plugged it into fan3.
