    I've got a Robo down for the count. It keeps having issues that started a few months ago. Extruder stepper skipping, temp error. I ended up changing the driver, installing E3Dv6. It ran awhile and now it would run and then have heat error. Then extruder motor started skipping, just no power to turn the motor. I really think my Ramps board is shot, but need some opinion since it's expensive. I had a spare Mega board and swapped that out to rule that out. Reflashed with Robo V2 and now I'm getting Maxtemp bed error. WTH. Opinions and options please!

    seems like something funky is going on, the max-temp is a shorted thermistor reading, either in the ramps, wires or thermistor itself for the bed. Extruder skipping could just be the Extruder stepper driver needs some tuning.
