I buy MK8 Dual extruder (link - http://www.geeetech.com/mk8-dual-extruder-p-921.html) and don't understand why you send me extruder with two heatsinks + fans if I need to remove them.

Ok, Why you sell it with two heatsinks and fans?

If I remove these parts the cooling will be worse.

Printer - Acrylic I3.
This MK8 Dual extruder (http://www.geeetech.com/mk8-dual-extruder-p-921.html) does not fit onto the dual extruder bracket for I3C printer.

The sanguinololu has EEPROM in the Atmega1280.
You need reflash the firmware to activate it.
Unmark this line in the configuration.h :
#define EEPROM_SETTINGS

Board: Sanguinololu 1.3a & LCD 2004 smart controller with SD card. Firmware: Marlin 1.0.3 Servo: Super-Micro Waypoint W-038CL Used control pin for servo: A1 (#30). Need to change the adapter board for LCD: cut track near A1 pin, connect A1 pin to A0 pin. SD card works fine. http://www.thingiverse.co...

I could not unscrew it.

Now I think that it is a complex problem.
1. Curved bed (varies depending on the heating)
2. Direct drive extruder that can not extrude plastic fast.
3. My ABS plastic from local supply that have infusibility more than regular ABS plastic.

Thanks!
