extruder motor issue

[taavet 0]

Hi All,

i just finished my brand new ultimaker and i am also struggling in making my first print.

There is continuous issue with the extruder motor. It runs under control panel well - i can extrude filament, the temperature is 210 (using PLA plastic). But when it what comes of printing, then the extruder motor starts up first, runs like 10-15sec. I can see the filament coming out from the extruder nozzle but then it stops. The extruder head is moving around, but nothing comes out unless i open the clamp and push the PLA cable manually forward.

Is anyone out there who might know the solution to that issue? Please?

Best, Taavi

Here are specs for software:

running ReplicatorG in OsX 10.5.8

ReplicatorG version 0026 (as the newest just wont start in my mac)

Firmware is Build1 because if i try to upgrade to Marlin experimental build, theReplicatorG Says:

Ultimaker not responding to RTS reset. Failed to connect after 4 attempts.

I think i found an answer: "dimension" plugin is off in Skeinforge.
