    I am having problems controlling my printer through MatterControl. The printer will not respond to the manual movement controls. For example when I push the Y+ nothing happens. Another problem is that the MatterControl is not reading the bed or extruder temperature. However, the printer does respond to the home controls (All, X, Y, Z). The printer was working and then I turned it off and when I turned it back on it started having these problems. When I press on a manual movement button and look in the gcode terminal I get a message that the printer was stopped due to error. Fox error and use M999 to restart. When I type in M999 it tell me that max temp has been tripped even though M105 says all my temps are zero.

    Here is what I have done to try and fix it:

    Download the firmware from Robo3D.com and load it to the printer. Nothing changed.

    Update the firmware through Matercontrol. Nothing Changed.

    Tried using repetier-host instead of MaterControl Saw the same behavior.

    I have looked at the circuit boards and there is no obvious damage.


    To me it seems like it is a software/firmware problem since I know the printer is capable of moving the axis (it responds properly to home commands). Any ideas?

    I was thinking "USB connection problem" until you said the homing controls all work ok.

    But just to be sure - when you connect using Repetier Host do you get a log file response from the printer? eg something similar to this?

    If you do, then the USB connection is probably ok.

    Another possible cause for what you are seeing is the extruder thermistor is not working - either shorted or open circuit. For example an open circuit extruder thermistor will trigger a MINTEMP error immediately. A shorted extruder thermistor will trigger a MAXTEMP error immediately.

    When I simulated a shorted extruder thermistor on my test bench setup I got this error message

    17:32:43.686 : : Extruder switched off. MAXTEMP triggered !
    17:32:43.696 : Error Printer stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)


    Once you have a MIN or MAX TEMP error most of the functions on the printer will not continue operating.

    What did you do to fix this? I have the same issue.

    Did you get replacement parts? If so, where?

    The hexigon hotened i ordered had a thermostat. That was the one that broke so I re-installed the original one.

    Seems like I may need a new one. The sleeves on the thermocouple slid down and created a short. I pushed the sleeves back up and that allowed me to manually move again...but now I'm questioning my temperatures because I am having issues extruding. I just cleared the nozzle and hotend with acetone so now I'm thinking its an issue of temperature.
