Overview
If the Viki displays the error message “Max Temp,” the hot end or bed is reading temperature above the upper limit set in firmware. (Bed - 150°C, Hot end - GB2-245°C, GB3-350°C on some and 400°C on others). If the hot end temperature is reading above 900C, it is a sign that the thermocouple wire or thermocouple extension wire has a break in the circuit.
Before proceeding, please collect and record the following data:
- Gigabot serial number
- Photo of the Viki with the error message
- Take a screenshot of the Simplify3D temperature graph when the error occurs
- .factory file and .gcode of part you were printing
- Did max temp error happen:
- While heating the bed?
- While heating the hot end?
- During the print?
Possible Causes:
- Hot end temp set above maximum temperature in Simplify3D.
- Break/short circuit in hot end or bed thermocouple (GB3 and GB3+)
- Break/short circuit in hot end or bed thermocouple extension wire(GB3 and GB3+)
- Break/short circuit with thermistor (GB2)
- Break/short circuit in thermistor extension wire (GB2)
- Thermocouple daughter board malfunctioning (GB3 and GB3+) BED ONLY
- Thermocouple daughter board jumper wire is loose (GB3 and GB3+) BED ONLY
Possible Solutions:
- Reduce temperature in Simplify3D
- Replace thermocouple. You can purchase replacement thermocouples here: Link to shop
- Replace thermocouple extension wire
- Replace thermistor
- Replace daughterboard
- Replace jumper wires
