Skew/Slant Issue On Larger Prints (Page 2 of 2)

Don't get mad at me, just have one last idea to try. 

Print this snowflake out and see if that works.

OK, here's a pic of cmetzel's funnyflake. I stopped it about midway through, but I think you get the idea. Basically a disaster.

Otherwise, as a point of reference, a pic is attached of some parts I made last week. As you can see, they printed without issue and are quite nice; obviously the machine did work. Something has gone horribly awry since....

I'm going to try running the little Tardis again and see what I get.

Haha! Might have been a neat part if it had printed!

Pulley setscrews are all tight. Belts are all snug. No odd noises.

Just re-ran the small Tardis. Results in pic - shift is confined to the X.

That was a thought also, so I had nothing other than e-mail up when I just re-ran the Tardis model.

But, I had been doing design work involving huge Inventor assemblies last week while running successful prints.

You CAN get this closer - it's tough...stick a screwdriver in and just put 'pressure' on it in the right direction, don't even feel for a turn, and remeasure.  I did this a few times, back and forth, and got it to register within 0.003V on my digital meter, and it still registered to within .003V (although the last decimal had drifted) when remeasuring a couple of days later, both before and after a print when the stepper control chip was going to be hotter.

All that said, I hope the board isn't so sensitive to voltages that your current .455V is actually a part of your problem, so this post isn't likely to be helpful....

Now you know it is the electronics at least.  Sounds like a bad wire, solder joint, or something of that nature.  It may work again if you allow it to cool for a while.  At that point, you should really inspect all the wiring connections and find out where it is.

OK, I think I'm back in business.

I powered down and unplugged/replugged the X-axis connectors. Then, on a whim, I decided to pull the setscrew on the X-axis pulley out entirely, blasted the hole out with some canned air, then reinstalled the setscrew. I powered back up, and loaded the part file that began this saga. I then left for lunch.

While I was gone the part printed fine.

It might have been a combination of the two, but I'm wondering if there wasn't a burr or tiny chunk of crud in the pulley setscrew hole. It seemed snug when I checked it before, but there's the odd chance the screw wouldn't seat and anchor the pulley properly.

I hadn't printed a part that covered this much of the table before, so I wonder if there wasn't a bit of slippage induced when it was nearing its extents on the X travel and things spiraled wildly out of control from there.

Now to see if it prints fully in the color I intended.....

Glad you got up and running again!  And, yes...This was an awesome example of a great Team effort!

If this were a business; it would be very formidable with all of the talent and experience coupled with quick response times!
