Y-axis belt slipping (Page 3 of 4)

I thought I had maybe fixed my Y-axis shift but the problem returns. I carefully cleaned off any old greese, gressed and recalibriated. Seems my Y-shift went away for 3-4 prints but it returns again. And the one last night was not that intense either, was only an hour and a half print at normal speeds and Y-axis skipped about 2 times just enough to ruin the print (not the filiment fault). I guess I can try to re do it and hope I just missed something. This Y-axis shift is getting really annoying as I lose every 4th print and have to recalibrate every 4th print.

I can only assume this post means your close to hopping back on the saddle to give it another go?

I played with my 3D printer this weekend. No luck. I have pretty much tried everything I could muster with the help of wardjr (without major mods). I am starting to think whatever the problem is not fixable or something.  I suppose I'll have to get to trying the finsihing line mod if I can muster the desire.

At this point and 3 months of struggle on the same problem I am starting to wonder if it worth the time. I've even begun to consider selling my 3D printer, but not really worth it since a SD2 isn't worth much, but I could probbaly sell the many rolls of filiment for more then the printer. This thought will likley pass but I feel meh know about it at the moment.

I forgot to answer this one. lol. I'll have to check. I think something mechnical has to be happening but for the life of me I can't seem to narrow it down to what. Wardjr has had me trying so many things but none seem to work longterm if at all.

Currently (ok maybe as in the last 4 months) it seems my printer will print reasonable well and then shift. Yesterday I heard like a thump or grinding noise and then half way through the print and then it continued but shifted on the Y axis. It didn't seem to be a filament tangle or anything obvious.  I have lubed everything I can find so I am confused. When I check the sliding when the machine off, it seems ok as I can tell.

+1 set screws get me all the time, too much fiddling I suppose!

Mox, your "thump or grinding noise" puts me onto the mechanical problem bandwagon (something like filament feed as you've already suspected). Is there any way perhaps the cables to the extruder are getting caught on anything?

If this was me at this point I'd be videotaping a good angle from the top of the printer (with sound) for every print I did until it skipped again, and finding the exact moment it happened (like the pitch drop experiment) so I could go over it frame-by-frame in excruciating detail (and also post it on the forum hehe).

Mox, have you narrowed down anything further to the Y-shift issue?

I had a thought...if I'm not mistaken you upgraded your extruder stepper driver to a 1/32...do you still have the old 1/16 that you can swap into the Y axis to check that out?

Just a thought since you seemed to have tried everything else under the Sun!

EDIT:  Make sure you power down completely before switching drivers!

Hey Tammy,
Sorry to here you are so frustrated.  You know we are all here to help so let us know what you need.
If it helps I would be willing to lend you my other SD3 if you cover the shipping both ways.  I'd even take the time to toss on some fishing line just so you can see how that works.  If that does anything for you... you have my email.
My point is that I think it is a bad idea to sell all your stuff as you have worked so hard to get to this point.

Yes...Stepper Motor.  I think I've got a spare one of those hanging around.  I'll check tonite to make sure it will fit and send it to you if you want...

Those may seem loose but I think  they are fine as long as the belts are snug.
Take Ironman up on his offer what do you have to loose?

Yes, especially considering the very nice items you create!
