leadinglights, it was very nice to see your experiments on the temperature dependence of the piezo elements, you made a nice rig for testing I wonder if your results were made worse by you using a voltage amplifier, as the voltage from the piezo element is dependent on the internal resistance of the piezo element, which drops with temperature. Since the piezo element acts as a current source, tby elenhinan - General
Joining the thread a bit late, but I figured I would chime in. I'm the Njål referenced in the first post btw. I haven't really used my printer much the last year, so there hasn't been any development from my side. Around christmas however I got a PCB of my circuit from a Korean user on thingiverse who implemented it, and obviously this is a bit more reliable than the breadboard version.
