    Someone please help I've been trying to print a new carriage for days now.ROBO shuts down 2 hours into the print 1st it was the hotend so I put themal paste in the hole to keep it from failing works great my temp stays a soild 225c because if I go 230c it errors. Now the bed is going from 100c 99c 101c I don't know if its suppose to do that but for some reason it just shuts down not moving temp goes down than back up with error on the screen I have know idea why the fan under the Robo is working fine. Has anyone had this happen and if so how did yo go about fixing that problem?

    Pull the bottom off and check all your connections . Most common cause I have seen. Push the connections on even if they look ok.

    What error?
    Details matter since we can't see what you see.

    Then your thermistor is bad or the wiring to it is bad or the connection to the RAMPS is bad or ... in rare cases... the ramps is bad.

    Swap another thermistor onto the same connection on the RAMPS (for example swap the bed thermistor with the extruder thermistor) and see if the problem stays or moves with the thermistor.

    185 reading on the thermistor I think means that you have the fan plugged into the thermistor port.

    Double check all your connections at both locations.

    Ha the wires were switched the thermistor is back to normal but 230c on the hotend it temp error if I keep it on 225 I'm ok to print. I changed the max temp in the firmware an the bed still temp errors at 99c and I set it to 115c

    You likely need to adjust max temps in the firmware and reload it.
    What lines did you change in configuration.h? Paste them in here with your changes.
