Topic: Filastruder only extrudes for a second before the motor stops

Im having a problem where the filastruder only extrudes for about a second at a time before the motor seems to lock up and stall. Without any PLA pellets fed into the device, the motor and auger spin with no catches or bumps in any way. After the pellets are inserted and allowed to flow up to the nozzle, the motor soon grids to a halt. After waiting about a minute, the motor can turn again but only for another second or two before stalling. My theory is that the plastic is cooling in the space between the heater clamp and the nozzle and the heater is not keeping up with the material flow, cooling and not allowing the auger to spin. The auger extends 5mm beyond the pipe's end and was allowed to warm up for 20 minutes before use. Any tips or suggestions would be appreciated!

Thank you

Noah

Can you post pictures of your setup?  Did you go through the Stall Protection board setup?

Re: Filastruder only extrudes for a second before the motor stops

It seems I have to extrude at 190C otherwise it wont extrude. The machine seems to cruise at 1.5-1.6 amps and the motor stalls at 1.7 amps.

Re: Filastruder only extrudes for a second before the motor stops

are you letting it sit at temp for at least 20mins before you start extruding? Is your stall board setting set correctly?

Where is your thermocouple?

What is the blue stuff?

That zip tie is likely to melt or deform and fall off eventually.

Blue tape is probably painters tape. Zip tie is nylon. not going to melt at pla or abs temps

Re: Filastruder only extrudes for a second before the motor stops

I have had to rebuild the thing a few times as my first barrel was bad, had a stall control board go bad, and countless other reasons. The white paper on the insulation came apart so I put the tape on there to keep the mess of yellow fuz at bay. The thermocouple is installed in the divot in the nozzle and secured with the zip tie. After some work, I found and letting the machine set and auto-tune for 30 minutes, I extruded lots of pla at a surprising 190C with good results. I then printed a perfect benchy and calibration cube on my CR-10 with the extruded clear filament. I was expecting to extrude closer to 150C from what I have read, but my results are without drying in an oven or anything and anything below 185C the auger locks up as it is too cool.http://soliforum.com/i/?48gP2Fz.jpghttp://soliforum.com/i/?wsHvWqU.jpg

As for as amps go, they actually seemed to drop to around 1 amp as time went on and a few scoops of material went though the machine. Seems happy at 190C so Ill stick to that even though its abnormally high from what I can tell. The PLA is 3DXTech brand.

My next adventure will be to get the fila-winder set up, it seems pretty hard to use from what what I can tell... It least I have tons of filament now lol.

Thanks!!

Noah

Re: Filastruder only extrudes for a second before the motor stops

Temperature is not abnormal, its relative to the position of the temp sensor on the nozzle.
It may be too hot where its at but the filament it self is not getting that hot where its at, get it ?
In any event, you absolutely MUST dry your PLA pellets before extrusion regardless of the fact that they came dry in a vacuum sealed bag.
