acrylic I3 motor issues

It appears that as the filament feeds in it feeds till the bottom of the nozzle then it seems to stop and form a plug at the end and seems to just squash down instead of extruding through the nozzle. some support would be nice

Is the teperature high enough?
Generally, it is 170-190 degrees for PLA, and 190-200 for ABS.
If necessary, you can raise it a bit higher.

i have tries raising the temp to 230 for PLA, it seems to help a bit but the same thing still happen after it flows for a while but then the motor still occasionally jitters.

Try to adjust the intensity of extruding by the thread.

I Have adjusted that screw. if it is lose then the gear slips after teh extruder blocks, if i tighten it the the motor jitters.

[zhangxueyou]

When you let the extruder work without filament, is the motor jittering?

[buzmal]

No the motor runs smoothly it seems to just be that the extruded becomes blocked

[zhangxueyou]

If the extruder is blocked, please raise the temperature to 230 degrees, then try to extrude the filament with your hand downwards.

Ok so success!! i have got the system the print successfully. i had to turn the e step down to 100, it was feeding way to much plastic at 700, and up the temp to 230degrees

[zhangxueyou]

Great! Generally, the e step is 100. 700 is too high.
If the filament is PLA, 200 degrees is enough, or it may become black.
