I updated using Arduino 1.0.1 with the firmware off the forum. I run Linux so I cannot use easy print.

Ok I've been having issues getting the second extruder to function. I've been through all the mechanical tests and they are all good. I am starting to think it is a firmware issue. I have updated the firmware. The motherboard is set to ultimaker and extruders is set to 2. The reason I think it is ...

Ok so I downloaded the firmware for my machine. After installing it, when I auto home the axis goes the wrong direction and the machine crashes. Does anyone have the settings for homing? So I can verify the firmware I downloaded.

I fixed to solder. I also reloaded firmware. Still nothing from the extruder. Now my axises are reversed so I'll have to fix that.
Changing the nozzle didn't fix the issue with the first extruder. I ordered a different extruder setup now if can get the main board fixed I might be ok.

The port I'm referring to is labeled A on the back of the board. 1 solder joint is only half soldered but the rest look fine.

Ok what do you mean by replace the extruder. The stepper motor works fine. I think it's the board. Nothing I plug into the second extruder port functions.

extruder 1: tried the paper trick. no go. tried raising temp. no go. how much force should it take to manually feed filament through a 0.3mm nozzle?

extruder 2: i can un plug the second extruder cable from the board and plug it into the x axis and it runs fine. i can swap the driver board to ...

Extruder 1: initially filament would not even feed. The holes through the extruder did not line up. So I drilled the out enough to get the filament to the hot end. Now I still have feed problems. I increased vref to 1.1v, temp is good, but I'm not getting enough coming out unless I manually feed the ...
