I'm building a repstrap with arduino mega/pololu electronics. The xyz bot is based on wolfstrap, using the base of an ikea Rast night stand I had around.
20100630 - finally took pictures of the working base electronics. got all 4 steppers hooked up and moving. have not yet designed/made the heater circuits/connectors or the inputs such as endstops, thermocouple/thermistor, estop.
