Post by nuproto » Wed Jan 29, 2014 2:53 pm

This is very annoying i been trying everything and i can seem to fix this issue..

as you can see i printed several prints all with similar issues.. wasted a lot of material and i'm yet to print a descent one..

i opened up the printer and looked for debris or anything messing it up.. i thingten every screw and lube everything thats needs to be lubed..

i dont know what else to do

Your build plate could be shifting or the plastic in the extruder is miss feeding (clicking) for a few seconds causing a gap in a layer and then the next layer does not have enough compression to stick, causing layer split.

Your machine mechanics are fine. The problem is either the filament not being uniform in diameter which can cause extudite width changes but most likely it is the information that you fed the printer. There probably are errors in the STL file you loaded. The file conversion process can often be troublesome. Troubleshooting this ahead of time can be very difficult and time consuming.
There is also an off chance that the printer's slicing software may be having some trouble converting your STL into layer code.

ggeezer could be right but it's hard to be sure from the information you've provided. You've clearly done the print several times. If the error is repeating in the same place this is most likely the model but can be verified by printing something else (a simple column) and seeing if you have issues at the same heights.

If the errors are in the same place between the same prints but not present on the alternate print (eg the column) it's either your model or an error in the Up software induced by your specific STL files - run it through cloud.netfabb.com to fix it.

If the errors are in the same place on the same print AND on the alternate test print - its something binding on your printer at specific places on the axes and not your STLs. Turn the power off and move the axes around gently by hand to feel for and binding.

If the errors are random between the successive prints then it's just as Drew suggested. First try printing with genuine filament - that will test Drews supposition about badly sized filament though I find the Up tend to slip if the filament is undersized enough to make that marked an issue in a print but printers are not all created equal.

There was one thing I forgot to suggest in my last posting.
Have you tried repositioning the model on the build platform by rotating it 90 degrees along the Z axis?
If you haven't, give this a try and see if the problem persists.

Is it always skipping on the same axis?

It could be the following:

If its always on the same axis,
skiping belt
stepper motor faulty
motherboard stepper controller (most likley from experaince)

Is it too cold around the platform? Maybe the layers are cooling too fast and separating?
