I replaced the feeder gear, old one was a bit worn but new hasn't changed printing.Just guessing, but how do the feeder gears look?
My printer has been acting up, prints have lost consistency and have weak spots in them. Tried printing the spool I modeled for Unstuck and it looks like this before it stopped printing... Listening to the printer it sounds like the filament is stuck like a clogged nozzle, I switched out the nozzle and it doesn't seem to help.
In this print the bottom is honeycombed then in the middle it acts solid before it goes back to honeycomb and spongy before it stopped printing. The printer is over 5 years old (ender 3). Hot end issue? Filament issue? Power supply issue? What would you do at this point?
something like this?Crunchy prints for us on the ender 3 were 90% of the time bowden tube. 10% fan issue.
I probably went through a metric mile of bowden tube on those printers over the last 4-5 years. I'd always just swap the nozzle at the same time, so probably 500 nozzles. When we switched to the ender v3 direct drive (think ke is the current one), problems vanished. Those printers almost never had an issue. 2 years on the same nozzle and fans, and no bowden tubes. They are 100x more reliable.
