Hello From TAIWAN

(English is not my native language so there will be spelling errors or grammar errors, please bear with me.)

Hi everybody,

After 2 months of assembly, and correction of X, Y, Z axis is finally completed.

Now there is a problem, and did not respond in the extruder.
Extruder how to test it?
I use LCD Controller and Repetier Host the manual control does not respond.
Repetier Host Response: echo: cold extrusion prevented, adjust your temps or lower min temps in your firmware.
firmware is Marlin-for-rostockmax-ramboLCD 2013-03-28

Why is my LCD Controller can not standalone prints!!
LCD Controller off when I put out the USB cable.

What happend? Too much pressure?

your hotend is not heated. or your thermistor is not connected properly.

rambo by default gets power from usb cable, to change this
move power selection jumper to 12v power supply on rambo board,

Thank you very much cambo3d, two problems are solved!
before hot-end is not heated to 200 degrees the extruder will not take any action!!
