Waynester wrote:Hey Guys,
This is very strange. I recently tried to print a part that I have printed successfully several times.
Now for some reason, when the layer height reaches about 3/4" it loses track of where it is and
the print head runs a inch or so off the path and continues thinking it's doing a great job.
This print job is a 3hour plus so I started a second try and the exact same thing happened.
I've checked all the belts and belt locks they seem fine. The first part of the print looks really good.
Until all hell breaks loose.
Any help would be great.

Mooselake wrote:This is a little far out, but it looks like you have those springy aluminum couplers. Any chance you're getting some bounce and causing the extruder to drag? Since you've found a quicker test print maybe you could stick some pieces of business card in the slots to stiffen them and see if it makes a difference.
Is the heat bed or x axis wiring hitting anything when it gets higher? Any strange noises when it starts happening? Can you edit the code to the offending layers and run it without filament to see if something's hanging up?

Anyway, if they were slipping wouldn't it show up on my callibration tests as well as live print ?

Waynester wrote:By the way Kirk, after I was up and running again I tried a test print. it started the skew routine again, so I ran your code again and it seems to be working out.
What do you make of that ?W.
