just as the title says I have a under extruding issue with my davinci 1.0 there are no clicking sounds comeing from the head but there is a popping sound almost like a over heated plastic popping sound. I am using abs but at temps between 225-235 the sound stays the same wether the temp is hotter or cooler. I have printed a ton of stuff at this temp no issues till now. I can get the under extruding issue corrected now buy turning the filament rate up to 130% and slowing the head down to 80 what would have caused this issue all of a sudden. I cleaned the head very well and insured that the bed is leveled and at a sheet of a4 paper away from the head. The head has not been removed at this point. Any thoughts or has anyone gone through this.

Have you tried cleaning the nozzle thoroughly? Retract the filament from extruder at 150 degress ish so not to leave the end molten bit behind. If you still have some pokey tools use that to scrape the nozzle hole out, if not a .3 or .4 pin drill is best, small resistor legs work in a pinch but not very strong. Other than that could the filament have absorbed a lot of moisture? I have lots of fish tanks in my room and havent had moisture problems so i wouldnt expect this. Let us kmow how you get on. Chris.

Potential issues:
New/different filament w/slightly different diameter.
Increased moisture content

I removed the filament and cleaned it pretty good moisture crossed my mind also the filiment is out in the open but I don’t have any thing really around it that I would think to produce thus issue could be wrong I guess I’ll try to clean it again tonite the popping noise is what concerns me tho

Cleaned it and even tried different filiment this is brand new never open first print and still huge issue so I know it not a moisture issue not sure how much more I can clean it any thoughts
That looks just like mine when the temp is too high. Drop temps 10°C and see what happens.
have you disassembled the extruder and cleaned the feed wheels? Filament “dust” can impregnate the knurls causing it to slip without the “click” evident with a major feed issue.
Snoobler thanks for the input I’ll try to drop the temp some more and no I have not taken anything apart yet been a bit nervous on that but I’ll take a look at the feed wheel also. To me it seemed like a slipping issue but never thought of a to much heat issue I’ll work on it when I get home from work and provide a update thanks
Ok so here’s an update reset the bed, removed and thoroughly cleaned the nozzle cleaned the drive and idler wheel dropped the extruded temp down to 220 and the new attempted print looks no different then then one in the image that I provided I’m at a loss at this point the prints aren’t a total loss at least I can do body work to them but it’s going to be a lot of work to correct this if it printed correctly it would be a lot nicer
I guess you have flashed you’re printer?
So if you ramp up the extrusion speed you’re able to print just fine with you’re printer.
My gues would be that there is to much friction on you’re filament so the head can’t feed it like it should or there is to little ( the gears might be misaligned or somthing like that.
