Re: problem with V3 extruder install

OK, thanks.

When I ordered the extruder, I selected the 19v option. Do you think they shipped the wrong one. If it's the wrong resistance, the watts will be low and it may be slower to heat up. Is this correct?

problem with V3 extruder install

I just upgraded my M2 with the new extruder. It is a good looking design. However, if I set the temperature for 200, it only gets to about 195and then slowly oscillates between 195 and 190, never reaching 200. I assume the PID coefficients need to be changed. Is this correct? I have never messed wit...

Re: Extruder - Popping noise and not feeding

Yep, you nailed it. Teeth are gone on the pinion. The Makergear website offers a 5:1 and a 13.6:1 gearmotor. I don't find any markings on the one I have. Any idea which one it would be? The pinion is 11 teeth, the 3 gears are 17 teeth, and the outer is 46 teeth. I guess I don't know how one works as...

Re: Extruder - Popping noise and not feeding

I disassembled removed the hot end from the print head and used a piece of .24mm piano wire to see if it was plugged. It seemed all clear. With the hot end off the print head, I fed filament into it by hand and with reasonable force got plastic out the other end. The first drive issue I found was th...

Re: Extruder - Popping noise and not feeding

Thanks jmc for the prompt and thorough feedback. I cranked the temperature up to 225 and it didn't help so it must be clogged. I have been running my temperature 20+ degrees too cool all along. I have the version 2 extruder from a year ago. Would there be any advantage to move to the v3 extruder? I ...

Extruder - Popping noise and not feeding

For quite some time, while printing, I hear a popping noise. It seemed random and maybe once every few seconds. I thought is was a belt skipping a cog or something binding, but could never "feel" or locate it. Print quality was OK. I recently did a "poor boy" stethoscope trick and the noise seemed t...

Re: Extruder keeps slipping

I only run PLA from 190-200 but I don't think high temp would cause what you are seeing.

Are others running PLA this high? I am getting decent prints but on occasion have had some delamination. Maybe I'm not hot enough. (I don't mean to derail the thread)
