Geeetech

Hi Everyone

A few weeks ago I bought my first 3D printer a Geeetech A10.
Its all been working perfectly but this morning I get a error after about 2 minutes saying "heating failed printer halted please reset" I have looked on the forum and see to check teh cabled which I have done and still it errors.

Could this be the fact that where I live today is a cold day (-1 degrees)

Or does anyone else have anything else I can do to make this work?

Hi，You can check that your hot end and hot bed connection is loose and then measure the thermistor.

Fixed it, appears it is a cold issue once teh room got over 5+ Degrees the printer started working properly again

The other thing that causes this is poorly set PID values for the bed (or Hotend) heater control.

Tune your PID settings for the bed with the following gcode:

"M303 U1 E-1 S90 C8" to run PID autotune on the bed at 90 degreesC for 8 cycles.
and
"M303 U1 E0 S245 C8" for the HOTEND PID (at 245 deg. C).

Don't forget to save the values to EEPROM, or the next time you start your printer the values will have disappeared
