Ender 3 - General discussion
Peter Cordell:
Second pic bottom right looks like a bulldog clip to me, as the nozzle sits back on the printhead i still feel its very likely the printer head has struck one or more of these clips working so closely to the bed edge
don't give up these are brilliant little machines when you have cracked it
ps the bed should not be touched by human hand if the prints are to stick to it, my prints for today
how i remove them
hoping these are correct tumbler gears for south bend L10 (downloaed from Thingiverse) if they are correct i will print some solid ones later

One similar problem (mine was with the X-axis) that I had that got my scratching my head for a good while turned out to be caused by the cabling getting snagged and causing the stepper motor to skip several steps. It was cured by providing a cable-support which kept the cables away from anything that they could snag on.
Might be worth checking that there are no hanging cables that can catch on anything.

I've had my Ender 3 for a year now but only just started using it; still on my first roll of Filament.
A couple of problems I've had is the factory supplied build plate had a warp in the "fibreglass" backing which made levelling a PITA.
I fixed it by rotating by 90 degrees until i found the spot whereby the bulldog clip would hold it flat to the heat bed.
The other is the settings in Cura having the bed as 220 x 220mm this caused to nozzle to crash the front bulldog clips on some larger prints. Corrected the settings to 235 x 235mm an not had a problem since.
Currently learning Fusion 360 which is the reason I didn't use for a year as I hit the wall! I can recommend Paul McWhorter on youtube () this has really helped me past the wall. It's called Learn fusion 360 or die trying!
Having fun learning

I don't have an Ender 3, but my I3 clone would do the same thing periodically. If you haven't done it yet, try re-slicing the part. Every once in a while something would glitch when the part was being sliced and the g-code got a little scrambled. I always figured that there's gotta be a lot of 1's and 0's flying around when the part is being sliced, and that somebody just got lost. I've switched slicing software since then and the issue hasn't reoccurred.

Thanks for the link there’s lots of Arduino there too! I had to google him as the link didn’t work.
