problems with extrusor

Post by juancr » Sun Nov 10, 2013 7:11 pm

Hi. This is the second time in one year I have this problem: the gear begins to touch the nylon part (don't know why, I think this piece unsticks from the extruder motor) and filament stops extruding, although printer runs "normally". When this occur, the motor makes a noise, as you can hear in the video below.
Had anyone some problem like this?

What material? Either your nozzle has a clog or the material isn't ABS and the extruded is too cold or too hot for it. Just guesses. :D

Thanks for your answers.
Nozzle cleaned, gear's teeth cleaned...
Always print with ABS bought to UP or spanish dealer.
Thought would be a problem with the diameter of the filament, so throw away about 1.5m and tried to print again, the problem persist and tried with an older filament which worked fine in past and the problem still was there...

I noticed in your video you posted that you have the clips on the sides of the perfboard, you shouldn't be placing them there, they are only needed on the front and back. By placing them on the sides,they will hit the frame of the machine and cause damage to your machine. I don't think there is anything wrong with the extruding part of the machine, something seems to be out of alignment, possibly due to the clips on the sides of the perfboard.

When you extrude the filament after changing rolls, does the filament come out smoothly and evenly?

Hi mb20music, thanks for your comments.
Clips in the sides are necessary because the perfboard usually bends with big parts, and I set them once the print has began, not before.
There's no problem with alignment, just the extruder: nylon piece was biten by the teeth, what I wonder is why. I suppose that piece unstick from the motor.
Will try to stick it again :-)

Yeah, I agree that's a bad placement for the clips. If you are having a warping issue, a) fighting it with clamping down the perfboard instead of letting it lift a little can be worse as it may result in splits/separation b) you are better of rotating you print to fit with your clamps. If for some reason you must clamp the sides it's best to remove the arms before the print starts. Even when apparently free they sometimes find a way to catch ruining a print and upsetting the printer.

Hi.
I think it is caused by the diameter of the filament... :evil:

Is the "cloc cloc" noise caused by the filament feeder "slipping" and not being able to feed the filament?
This is described on page 50 of the UP+2 manual....sob....yes...I did. I read the manual....the shame.... ;)

It's actually caused by the stepper motor that drives the feeder missing steps and not turning.

Hey Juan Ca yo tenía razón , después me quede pensando pero yo ya había tenido su experiencia y también había pensado que había limpiado la boquilla pero no y aprendí realmente a limpiar las boquillas , yo lo hago desmontando y quemando los residuos internos con una llama y después terminó con una broca no tan fina para no dañar el orificio de salida por último acetona y a contraluz para ver el orificio limpio .
