X-Y Inaccuracy...?

[brentwerder 13]

Hey everyone!

After just recieving a bunch of rolls of colorFabb filament for my birthday, I've been printing non-stop for the last week! I'm just starting the Chandelier of Fear project (thing:493016) for Halloween, so that's pretty exciting, too.

But, sadly, with the good comes the bad. After printing the three parts of the Screwed Cube (thing:693892), even though I had tweaked the print settings for each one as I went along, I noticed the same problem on each one: The top-left corner of each one was all messed up. The infill was about half a millimeter away from the shell. I changed a couple more settings like print speed and temperature and printed a new design (a cap for a SodaStream bottle), and the same thing happened - top-left corner had a gap. Again, I changed the settings and printed an arm for the Chandelier of Fear, and the gap actually went all the way through - the shell was at least a millimeter away from the infill.

I gotta say, this one really got me. I have no clue what went wrong other than some X-Y inaccuracy issues.

Here are a couple of print settings I've been using:

Material: colorFabb Black/Silver PLA/PHA

Printer: Ultimaker Original +

Temperature: 225-205 -changed during print, no visible changes

Acceleration: 2000

Print Speed: 40mm/s

Layers: varied from .2mm to .05 - again, no visible changes

Any help would be greatly appreciated!

To me it looks like under extrusion. I don't see a x-y shift. Maybe you have a partly clogged nozzle.

Awesome! Thanks for the quick replies, guys. I actually just cleaned out the nozzle using the old acetone/blowtorch method, and that cleared the nozzle out entirely. It might have clogged since then, but I hope not. If I have to, I'll do it again.

Also - I checked out that website and it's awesome! I'll try out some of the suggestions and post the results.

Uh-oh. I printed the next part of the chandelier and the same problem came up. I read every article on the website rigs linked, and tried out a few of the suggestions - nothing changed! Aaah! Any other thoughts on what might be going wrong?

Thanks,
