I don’t know what you tell you - I must be able to bend the rules of physics then:
The PFTE tube inside the nozzle may be the problem,
If plastic is coming out of the extruders when loading bed could be too close to the nozzle try reloading with the bed further from the nozzle. Also 230 is way too hot for PLA I normally run between 180 and 190 depending on brand
Today I did some big prints with my new spool holder and the issue seems to be gone… The spool I made can be seen here : http://www.instructables.com/id/Spool-Holder-for-Flashforge-Creator-Pro-FFCP/ 14
Can you push filament through manually?
If you can then my best guest is the filament drive gear. It may have crude on it and can’t grasp the filament to push it through or alternatively the gear that pushes the filament up against the drive gear isn’t tight enough that the drive gear can’t grasp the filament.
I can push it manually, then it stops. I just took everything apart, did not brush off the drive gear as it looked ok, soaked extruders. When I put it back together, loaded the filament, and one small strand came out and stopped!
If the gear that pushes the filament up against the drive gear isn’t tight enough, how is that fixed? Can it be tightened somehow?
Are you sure you lined the drive feed back up correctly when you put it back together. If it is off it will not feed correctly.
Is the stepper motor running?
You can push it manually through before it stops going through? Or are you saying that when you push the filament through manually it is fine but when the printer tries to feed it through it will stop?
If it is the first I would imagine there is still a clog. If it is the second then I think the spring to the extruder is miss-aligned or the bolt needs to be tightened a bit more. Could also be the drive gear is getting worn and needs to be replaced.
Have you checked out the troubleshooting section onthis page: Flashforge Professional 3D Printer Manufacture - 浙江闪铸三维科技有限公司 26.
Also just a side thought, have you tried printing with a different filament? Bad filament could be the culprit too.
Not sure what you are trying to show me here but that black rectangular cube you printed does not look very good if you are trying to prove to me 205 is an excellent temperature to print ABS. You are most definitely having bridging issues. You should probably use a cooling fan for bridging if you are not. How could it possible hurt to use a higher temperature? But whatever works for you. PLA melts at a much lower temperature than ABS so it would make more sense if you use 205 for PLA and 220-240 for ABS.
Sure. Take the fan and cooling sink off. Remove the stepper if you want or you can just leave it on the cooling bar. Look at the feed guide and the roller. Make sure they are lining up. Let me know if that was the problem. If not you might need to remove the extruder head and check the teflon tube if you have not done that.
