Re: How did this happen?
slow it down on the g code page and see if that solves your problem.
I changed it once a few months ago but can't find the max filament speed anymore. might have to slow down the speed on the config page

Re: How did this happen?
I'm starting to get depressed. Everything was fine until it wasn't. Now I can't print anything. I swapped out the hot end and it still has problems feeding. At the same time I seem to be getting excessive drool when heating. I went to swap in my Chinese made hot end only to find out I have to print Lawsey's hot end mount. Of course being unable to print anything precludes me from doing so. It's rather frustrating. Any additional suggestions would be greatly appreciated.

Re: How did this happen?
Slowing down doesn't make any difference. I can hit the extrude button over and over and it just keeps extruding, but when I start a print, a small print at that, by the second or third layer the drive wheel is skipping and the filament is not coming out. My extruder fan is running and I did try baking my spool out. I'm having the same problem even after swapping hot ends. Does anybody have any other suggestions? All help would be greatly appreciated.

If you want to eliminate the filament from the equation perhaps buy a brand new roll and see if that helps?

Did you adjust the tension on the bearing? I have been having the same issues, it's a bummer not printing.

Did you run PID autotune from RH? Seems like your hot end isn't getting hot enough, perhaps.
Re: How did this happen?
Sorry for not posting a follow-up, I'm printing again. Unfortunately I'm not sure what the problem was. I'm leaning towards my temperatures being too low. I seem to see a correlation between the extruder temperature and the filament drive skipping. Unfortunately I changed a bunch of things trying to resolve the problem and can't be sure exactly what fixed it.
I talked to the creator of the BukBot printer earlier this week. He suggested that to find the correct printing temperature for a roll of filament you should reduce the extruder temperature until it starts skipping, then increase the temperature until it starts feeding correctly and use that temperature for that particular roll of filament. So far, so good...
Speaking of the BukBot printer, I was pretty impressed. The extruder moves in X and Z while the heated platform moves in Y. It's heated bed apparently will get up as high as 150C. He's using synchro mesh cables instead of belts to drive his stages and the printer is very quiet. The kit price is about the same as Solidoodle, the assembled printers are a couple hundred more.
