I’ve had a Flashforge Creator Dual printer and octoprint running fine for months with no problem. Recently I lost my settings for octoprint and cura. After setting those up again the printer prints fine but the bed doesn’t heat up. After the bed heater command FF is returning a message something like “bed heater command ignored because bed heater doesn’t exist”. This makes octoprint report the actual bed temp as “bed: off”. If I preheat the bed temp the heater works fine so I know the heater and thermistor are good.
I assumed the problem was in octoprint or cura settings but the error message is returned by the printer after a good bed setting command. I tried clearing the FF settings and erasing the eeprom with no luck. I’ve power-cycled the printer after each change. I can’t test directly from Cura because it doesn’t support GXP.
Has anyone seen this error message or have any idea for things to try? Should I re-flash the firmware?
The asterisk is the field marker for the checksum which follows it. It’s a field marker character just like the letters are.
For example, from your log “N10 G92 X0 Y0 Z0 A0 B0*107” means: Line number 10, command G92 (set position), with arguments values of 0 for X, Y, Z, A, and B axis. And a checksum of “107”. The checksum is simply the XOR of the ASCII values of the characters that proceed it. In this case, their hexadecimal values are:
