Last Friday, while Pilvari Pirtolas had his opening here at gallery Titanik, I was sitting in an adjacent room and fiddled with my machine. I had managed to get the extruder to heat up and the thermistor to register in Pronterface — a previous day of troubleshooting revealed that I’d connected the hotend to the wrong two pins of the Gen7 board — and now it was heating up with no problem and only a slightly worrying amount of smoke. Once it was mounted on the Accesible Wade’s extruder I was good to go for extrusion test.
I got some visitors from the opening next door, and it was fun to see some people react with curiosity and others with disinterest to the machine. To the uninitiated it looks mostly like a heap of metal and plastic, so the awesome disruptive power isn’t always readily apparent, so I got to practice my pedagogical skills on young and old, tipsy and wasted alike. Once I realized that all motors had the wrong polarity in relation to the Teacup firmware, I pressed “reverse” instead of “extrude” and lo! there was extrusion and much exaltation all around!
