Recently I bought the Geeetech Prusa i3 Pro C. It's their new dual extruder with what they are calling a GT2560 board, "The perfect combo of Arduino Mega2560 + Ramps 1.4."

Where re to begin.
I guess the first issue is the End Stops. I have 6 ports and 3 end stops. As per the instructions they were plugged into the X,Y,Z Max ports and the steppers would only move in the direction AWAY from the end stops.
After going back and forth with China and them constantly asking form pics, they told me to plug into the Min ports. It fixed the problem, and I went to bed.
the next morning I booted up the machine and it only moved in the direction of the end stops.. Geeetech wont respond. And I can't fix the problem. Changing ports repeats the problem with consistency.

Next. When Heating up the extruders they hit max temp and error. I've set the max temp to 220C on the Repetier Manual control. I've set it in the Printer Config, and I've set it on the LCD control of the printer. Heating goes to max, every time.

Exteuder motors won't run even when heated within the appropriate range..

i guess thats hats a good start.

thank you in advance for any help you can give,

Zan.
