Red LED light on the Printrboard
Hello everyone!
I'm a completly newbie in the 3D printer section and need some help.
I build together the Oneup and wired up the Printrboard. Mine is red and not black as shown in the manual. For the first time it lightet red, and not green. In this forum I read about the power connection flip and that the positive wires are on the side that looks to the inner of the board.
The powersuply has now the green light but not so the board.
I could install the USB driver and connect it to the repetier host. But I cannot control the extruder manually. The home button did move the motors. Afterwards I read that when I don't have any endstops I can't use the homeing buttons..
I also tried to flash the firmware as described in this forum but it fails and says the arguing.h file is missing.
If I try the g92 code, the log says unknown command..
So.. What should solve my problem?
Do I have to flash anything to the board or is it pre-flashed. What does the red led mean? How do I home my extruder?
Thank you and sry for my English :)
