In case anyone wonders... the lower jerk setting did quiet down the machine. Still some ringing, but I discovered an additional problem which I will open in a new post as it seems worthy of its own topic.

Thanks all for the insights!

In case anyone is wondering... the desk fire turned into a 4-alarm. Back at it, I discovered the V4 filament drive exploded. More on the ringing after I get this fixed.

Thank you! I am on it! Well I will be on it after I put out a desk fire this morning. (:- )

Hi, my last print looked really poor (attached). The part was printed with the right edge of the image on the bed. I suppose this is ringing? The profile is one I've been using for a while after some many tweaks (speed 4200 fyi). Slicer Simplify3D. Everything feels tight, but the machine seems noisi...

Thanks for the images... my parts have now little marks on them also! Ah, good input about the filament path being slightly different from a hand-feed path. It is hard to see, but when I removed the roller bearing it did seem a little 'rough' down where the filament would plunge into the bottom of t...

Update: 1. The filaments are partial spools I've used in the past and have been stored cool and dry with desiccant so I think they are OK. They measure 1.75 to 1.80mm depending on where I check. 2. I can not see an opening between the gear assembly and the stepper motor that shows the stepper motor ...

Ahh, thanks for the insights! Hopefully my Snark won't turn into a Boojum!

Everything works great, then I change filament and filament now won't feed...pinion slips on filament. Bite in filament looks OK, but tried different adjustments. Tried a different filament spool, still slips. Checked that pinion set screw was tight - yep. Doing that, I noticed the extruder motor sh...

Thanks for the reply! Back on the forum with another problem. I don't usually look at forum as I am such a noob that I don't feel I have much to contribute. I did end up putting on a V4b hotend along with a lot of other work. Someone had partially disassembled the M2!? Luckily Support was ultra supp...
