A failing driver is very easy to check on the sang right? Just swap two axes. I'd dive in and buy a new motor no question if I was having this problem. They aren't expensive ($25-$30).

I haven't been able to really diagnose it due to conflicting schedules.
However, I started having a X shift yesterday...every single print shifted about 4-9 times just on the first layer alone. After 15 minutes and a hunch, I found the problem to be the right X pulley. I took the screw out to look at the pully since I noticed a slight tilt, found a lot of black greasy powder at the bottom of the pulley that meets the carriage. I slapped on an M5 washer at the bottom, greased the top of said washer, then greased the screw. I was able to print for two hors successfully before hitting the hay.

This makes me wonder if it could just be as simple as greasing the screws, or a failing motor/driver in your case.

AZERATE, did you have any luck in resolving this? I admit I just stop trying on mine LOL

Your ears must have been burning AZERATE and I just had a conversation about your printer last night. Seems as though his printer has developed a similar problem. The good news is now you two can bounce ideas off one another.
Good to see you back.

I have after much(days) adjusting got my printer to print 3 items without a shift but I can't directly attribute why it is at least temp working. Whatever it is seems to have to be "just so". In the past months even when I got it working, it lasts a few prints and then start shifting again, so I am limiting what I print to things I really need. It's a shame, but at least I have it working sortof for emergency items.

Yes, especially considering the very nice items you create!

Do you know how many used printers I have bought from frustrated users that finally threw in the towel?
Never has one of those been something that I couldn't fix usually within an hour of receiving them. Don't become one of those people.

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?

One thing else I have noticed is that the little screws that hold on the belts to the carriages seems kind of lose. They have a washer attached to them, but I am not sure they are supposed to be that way and they are in so hard to reach I am not sure I could tighten them if I tried. lol

I can say my shifting is almost always backwards, like it has a filiment bind but it don't have one. I even of late resecured any lose wires to make sure it was not snagging.

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...

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.

What about the box that is on the lefthand side that attaches to the small belt. I don't know what it is called but it seems to move the smaller belt to move the Y-axis. It seems electrical and/or mechnical. Could that be bad? Where can I get a new one?

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

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

I though I had it fixed maybe. Managed to get through an hour print without an issue. But then the next print it returned horribaly. I suppose I should try the fishing line thing but I havent been able to print so long it went out of my mind and I'm considering packing it away selling any filiment I can and just waiting till I can afford a new printer. I don't mind tinkering with the printer but after countless hours of tinkering and dollars trying to fix it I am probably giving up. I just don't find fun in spending a week+ adjusting it to get a single hour print and if even that as it is getting worst in the amount I need to adjust to get anything to print right.

I do have some 1/16 sitting about. But would the extruder stepper driver mess up the Y-axis?
