I'm having trouble switching off the HBP. The software tells me to set the temp to 0 to disable the heated plate but if I do that (or indeed any temp below ambient) the printer sits in "pre-heating" (seemingly actually trying to attempt 0 degree temp on the build plate) and never progresses.
I've tried commenting out and removing the plate temp set up lines in the gcode startup and it just heats the extruders then hangs. Removing the plate temperature setting altogether has the same effect.
I'm probably missing something obvious but any ideas?
Thanks!
