Hello together,
I have continues problems with printing anything for over 2 weeks. :cry: I've tried a lot of things.
My setup:
Firmware: Marlin 0.9.3
GCode Software: Netfabb 4.8 and lately 4.9, also tried RepG GCode
Printing: usually ReplicatorG, also tried Printrun and lately Netfabb 4.9
Short problem description:
Filament won't extrude after first layers at normal speed when printing.
When feed by RepG (230°C,speed 2000) everything works fine.
Heres my detailed problem description:
First of all I thought my extruder gear won't grab the filament ending up in stripped filament.
So I tightened the filament feed mechanism and made sure the filament will be extruded towards the extrusion head.
This resulted in this: https://picasaweb.google.com/104195486315479086890/UMPictures#5723100012579085314 (short video)
The feed mechanism I not able to put enough pressure into feeding the filament to the heated head.
Then I opened the feed screw, heated the head to 230°C and tried to push the filament by hand. This is nearly impossible.
But if I heat it up to 230°C, and let RepG push the filament out at a speed of 2000, everything works fine.
It just seems to me that I'm not able to push out filament at a high speed.
When printing something, the first layer mostly looks real good.
But after the first layer, the head seems to stop extruding, the filament get's stripped and the print fails.
Example 1:
Example 2:
Another strange thing is that I cannot pull-out filament by hand when head is at 230°C.
This worked for me before and I also had some great quality prints. (e.g. http://www.thingiverse.com/marcusp/made)
Additional Infos:
GCode Header in Netfabb:
M92 E14
M106
M109
Temperature shown when printing in RepG: 185~195°C
Does anybody has any suggestion for me ? Maybe someone had this problem before.
Please Please help, I'm some kind of depressed.
