Extruder Motor not working

[maybites 0]

Hi

I just completed the construction of my new ultimaker and everything worked fine. I was able to use ReplicatorG's ControlPanel to control all motors, including the extruder motor, and was able to extrude some material as well. but after I tried to print out the first model (I followed the steps in

http://wiki.ultimaker.com/Newcomer_guid ... t_3D_print

) the extruder motor stopped working when the print job started. And now I am not able to control it anymore via ControlPanel. The motor itself works fine - I attached it to the Z-axis motor plug for testing.

Update: Now I am able to control the motor, but only if I unplug the usb and restart the ReplicatorG after trying to printout the model.

cheers

Important first questions:

Did you change the firmware? (Else you are on 5D stock firmware)

Which version of RepG did you use?

Can you post the generated GCode somewhere? (

http://pastebin.com/

for example)

Sounds like you have two problems we need to sort out:

1) Extruder motor does not work during the 'build' process.

2) Extruder motor does not work in manual control mode.

Problem 1)

It's hard to track down the problem based on the opening post. Answering Daid's questions will help to get to a solution.

Problem 2)

There are some known issues in Manual control mode in RepG with the extruder motor. Responsiveness of the extruder's buttons is really bad for some reason. The extruder motor should work just fine in 'build mode' though. Your non-running motor may be related to problem 1 but it might as well be this known issue...

First Daids question:

The ReplilcatorG says: "Machine Ultimaker v1.0 (ADVISED 5D firmware) ready"

ReplicatorG 0025 for OSX

2) seems to be not the most pressing issue anymore since I can reset the machine and using the controlpanel again (I actually plugged the motor into the wrong plug after my test).

1)I posted the first lines of GCode here:

Great. That also instantly shows what's wrong. Many of those "G1" commands should have an E value (E controls the extruder motor)

Which is most likely caused by the "Dimension" plugin not enabled. So you'll need to enable it. (Quick guide: Open RepG, press "generate GCode", press "edit", open "dimension" tab, enable it, save all settings)

No Success. I followed the given instructions and enabled the dimension plugin (Activate Dimension inside Skeinforge Settings) and the E Values dont appear.

Did you try to print that GCode? Because it does show E values for the first set of G1 codes. The other set of G1 codes might be cooling (Set the cool plugin to "slowdown" instead of "orbit" with a time of minimum layer time of 10 seconds). I also recommend you disable the "temperature" plugin, and just preheat yourself before printing.

It works now after making these changes! It prints now, expcept it seems as if the default settings dont provide enough material-feed. but thats a different issue.

Thank you very much for your speedy suggestions to my problem. I really appreciate it.

You're welcome.

The feed issue could be mechanical, not settings.

For me on my first prints the hobbed bolt was slipping on the large gear. So the gear was turning, but it was not really pushing the filament. So check that the bolt is rotating at the same speed as the gear. Then you could also check if the filament itself slips (and tight that screw a bit, but don't tight it to much!)

Then again, it could be the feedrate settings. Upgrading to Marlin with SF41 or higher is highly recommended so you can use the filament diameter instead of the kinda awkward feedrate settings. (Skeinforge_pypy: viewtopic.php?f=8&t=153 is also an option, it has all the settings pre-configured for the ultimaker, but it's still a bit experimental)
