You can try the installer version of 1.05,see if it works.

Maybe the driver is overheated? Please make sure the driver is cooled well.

You can also disassemble the feeder to see if there's anything wrong:

Hi,
It's not easy to flash the firmware in linux, you'll need something linke J-link, minicom, and we haven't tried that yet.
You'd better use a windows system to do that.

Hi Fernando, Seems the extruder doesn't have enough power to push the filament during printing. You can try to incease the driver voltage, or swap the driver of extruder with other axis, see if it will make any difference. Refer to this link to adjust the voltage: http://www.geeetech.com/forum/viewt...

The extruder problem might be because the driver of extruder is overheated, you need make sure the driver is cooled well, or you can swap the driver of extruder with other axis.

There's difference setting for 12864 and 2004 in firmware,

The picture failed for some reason, can you post it again?

Hi Rob,
There are the instructions to install the driver in this path:
Atmel\Flip 3.4.7\usb\UpdateDriver\w2k You can update the driver according to the info there.

Perhaps the crystal oscillator doesn't work on the board, you can check the voltage of the two pins to GND, normally they should be both be about 2V, the difference of the two voltage is about 0.2V

Could it extrudes normally when you manually push the filament with hand?
If not, then it might be the hotend getting clogged, you can try to clean block and the nozzle, see if it helps;
