Geeetech A10 Motherboard upgrade

thingiverse

With thanks to Bruce Greenleaf for his help. I wanted to upgrade my A10, it was one of the first produced so has the GT2560 RevB board. The reasons for upgrading were to have the new features such as filament runout, Resume print etc, the new board also better 5 Volt smoothing and a more constant heating of the hotend. There are a few physical changes required because the motor cables are different and the Power feed to the bed has an alternative wiring layout, if not altered shorts the PSU. I suggest you re arrange the pins in the Heated Bed plug first, because if you can't do that there is no point proceding. You can buy a tool, but its very easy to use an ordinary paper staple to slide down the side of the pin and it releases the barbs holding the pin in the casing. before re arranging the pins in the plug, very gently prise them up, so they will once again lock in the housing. The attached pictures show clearly the new order that the plug should be. so before you begin, Gather the required parts.
