Extruder Controller v3.6
The extruder controller is a compact little board based on the Arduino Diecimila. This board contains all the electronics required to drive one extruder, as well as extra electronics to drive a heated/automated build platform. It has built-in USB, so you can talk to it and program it with a normal USB cable. It has been redesigned with much higher power needs, so it has an ATX power header to provide the power. This means power is not coming over the RS485 cable which has the side effect of reducing noise.
High Power MOSFETs
This extruder controller is a powerhouse. We pored over datasheets to find the perfect MOSFET for our application. These MOSFETS don't even break a sweat when controlling demanding loads like the MK5 extruder or the Thing-O-Matic® Heated Build Platform. Both of those can draw upwards of 5A at 12v. Gone are the days of relays and workarounds for weak MOSFETs that overheat.
Thermocouple Support
Accurate temperature measurement is critical for high quality 3D printing. Thermistors are nice for general, low-quality temperature measurement. Once you get above 150C, it's time to step it up. Thermocouples are a really solid way to measure high temperatures. They are accurate, reliable, and high tolerance. They also have the side benefit of being easy to mount. Simply bolt the thermocouple to the side of your thermal core and you're ready to go.
