Has anyone printed any ABS with the R2? Here's a screen shot of my bed attempting to heat up to 110 deg. Two issues: #1 it took 20 mins just to hit 90 degs with the door shut, that's just unacceptable. #2 when it hit 90, it errored out with "Unhandled communication error. The was an unhandled error while talking to the printer. Due to that OctoPrint disconnected. Error: Heating failed, system stopped! Heater_ID: bed". It happens consistently... Anyone had success with bed temps above 90? Any clues before I call Robo?
