Now that my AXIS is no longer in a workable condition I thought I would try to repupose the parts from the printer into something usable.
This past weekend I built a dry box for my filament. I took the glass that I purchased for the AXIS bed and used it as a platform. Under the glass I attached a reptile heating pad. This platform set off the base of a gasket sealed 54L plastic box. I poured about 1kg of desiccant in the bottom and added a hydrometer and thermometer.
I had hoped that the reptile pad would heat up more than the 28C.
To build the box I also used the couplers that came with the dual extrusion upgrade for the printer.
While I was admiring my handiwork I thought, "wouldn't it be awesome if I took the heated bed, mosfet, and 24v power supply and replaced the reptile pad with it instead?!" I figure if I could do that then I could get to ~50-60C. This wouldn't be a dry box but a drier!
So, here's where I am. I have the heated bed. It will attach to the mosfet control like it is in the printer. I'll get an Arduino Uno, a digital encoder, and a LCD display (or better yet the LCD and encoder from the printer). Next, I'll make a little case that holds the Arduino and the display and mount it in a box. The thermistor will run to the Arduino and work the PID temperature control code based on the control. I can reuse the barrel connection to connect the 24v to the mosfet board. The Arduino should be able to send a PWM signal to it.
I'm not the best at this stuff. I'd really be interested in getting some help and then writing up an instructable!
