Re: Solutions for GT2560 extruder not working

Hi! Im Vero from Argentina!
The extruder of my Geeetech I3 ProB is not working correctly. I upload the frimware available in this forum but its still not working correctly.
When I set to extrude 100mm/s It extrude only 10mm/s (but this shows that the motor works), but then when I send it to print the motor of the extruder doesn't move even a little.
I have another extruder so I changed it in order to identificate the problem, but it happens the same thing. So the problem is on the board. Then I changed the controller chip (or driver chip) and mesured the pololu but these things are OK..
Someone have any idea what could be the problem? and any solution? Can I do some changes on the frimware and exchange Extruder 1 with extruder 2 pin or something like that?

I really appreciate your help :D

i,
I put the new marlin, but now for the X-axis should not be more right, is on the contrary.

I downloaded the new Marlin firmware but when i try to compile it in the auduino, i get the following errors.
What do i do to correct this?

Also how can tell what version is in my board now vs what version this - just wondering if maybe i already have the most current firmware. My board/printer what just shipped to me last week.

i am having the same issue as others, extruder is barely feeding or not feeding at all. I have checked the nozzle and its fine and not clogged. I can manually push filament thru it no problem when it hot.

I was able to fix the issue of not being able to compile by dropping back to ver 1.05 of the Arduino software. This allowed me to update the firmware in the controller board. This fixed my reverse X axis issue, but I am still having problems with the extruder. If i turn the flow up it seems like it does not make any difference. I tried turning it up via the speed and via the flow settings in the LCD menu, but i am not seeing any noticeable increase in the filament flow. I get tiny amounts of flow but not enough to print consistently. Please help with anything else i can try. I have been working on this issue for 3 days now and don't seem to be making any progress.

Hi,@wespiece
You mean you have no sufficient filament coming out during printing?
Refer to this post to see if you have the same probelm:

Yes that is exactly the problem. GEEETech needs to step up and include the better quality extruder. Mine was slipping as well. I 1st tested the theory by wedging a screw under the thumb release lever. I could see that it started to catch and move the filament. From there i did like they said and modified the extruder so it would roll tighter to the gear. For now i have resorted to stretching the spring. I have ordered the upgraded extruder for $7 off ebay.
Why would GT no just include this. I'm sure this has caused tons of frustration for new users. All to save maybe $3

hey what kind of extruder upgrade did you used? I also streched the spring but it still skips filament

I ordered the Geeetech aluminum model. This one seems to be better but i still had to rig up a spacer under the spring to keep extra tension on the wheel.
