prints have been:
angle 20 degrees
I have had issues with the material not extruding out of the nozzle part way through prints. Seems to load the filament fine but then generally will stop extruding material at some random point through the print. The gear will have eaten into the filament. Applying pressure helps it push through again.
I had printed a run of parts and had no issue. Then put in a new roll of filament. Used the same file to print some more parts and the issues began.
i have done the following to track the bug:
-I have checked the file and it has no errors. i have also tried new files with the same problem occurring
-Cleaned the nozzle in acetone over night. Ran material through the barrel without the nozzle to make sure no bits have been clogging it up.
- Tried another new roll of abs, (purchased at the same time as the previous roll)
-I have now put in a new v2 hotend and nozzle assembly.
- I did try an older roll of ABS in white that did seem to solve the issue.
When i cut the newer ABS rolls i did notice that there was a small pin hole cavity running up the middle of the filament. It seemed to be intermittent along the filament wire, as some cuts didn't show cavities. It was as tho there were some air bubbles during the filament manufacturing process.
Could a bad batch of filament cause this issue?
If it was the ribbon cable i would expect it to happen with the older batch of filament as well.
The machine is only a couple of months old.
Any help would be much appreciated as i have spent a significant amount of time and filament trying to trouble shoot the issue. And need to get some parts printed as soon as i can.
