I'm getting a similar issue with the AD595 board using a thermocouple. Whenever I hit the extruder, temp jumps up about 50C (from 250 to 300). But when I extrude by hand by physically turning the gear, it works fine.
Right now I've got the AD595 kit board from Makerbot hooked up to AUX-1 pins of RAMPS 1.4 (5v, ground, and Analog 3 on the Arduino Mega). Is there a way to do this without having to add capacitors?
