Geeetech

Hello everybody,
I just bought an A20M and printed successfully the example inside the SD card. Then I followed the manual to import the settings (both of printer - first part of 6.2 manual's section - and filament - Geeetech A20M PLA high.rcp - as well. Now I downloaded an stl file from thingverse and opened with repetier, using the settings just imported, then I sliced it with curaengine and exported it with "save for sd print'" copying file to the sd. But once inserted and started printing printer heats only bed not extruder (that is still on 0) so when bed is warm enogh printer gives "temp too low". It seems to be a problem in the file but I do not understand why, because I followed all the steps inside the manual!! check omegle

Check you are setting the correct extruder in cura.
You should have 2 extruders and disable the extruder you dont have any models to print.
For example, if you are using extruder 1, disable extruder 2 by clicking on the checkbox.
