Im using a RUMBA board with the MARLIN 1.0.1 firmware to drive a BFB 3000 printer Mostly its working, I can control XYZ motion and turn the extruder heater on. Issues I'm having seem to be related to the thermistor set up when I first connect to the printer i get " 11:05:04.695 : : Extruder switched off. MAXTEMP triggered ! 11:05:04.766 : Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting) " And the temperature curve shows an initial spike to 350 degrees and then seems to be stuck at 99 degrees and I'm unable to elicit a reaction from it (even by just bridging over the connections to the thermister point on the board) any suggestions on what to do to troubleshoot this issue?
