GPIO controlled drybox?
I'm thinking of building a 90C drybox, and I was thinking, instead of getting an extra PID controller to run it, could I use the GPIO module and have the printer do it for me instead?
I can figure out the enable/disable, input/output part of this, but could I add an extra thermistor and run a PID autotune? The board will be connected to a SSR via a thermofuse to controll a 400W PTC and there should also be a servo to open/close a vent.
Thoughts and advice welcome
