Nozzle Drag and Print Voids

Recommended Posts

Posted · Nozzle Drag and Print Voids

Hey all, 

I am on my last part of a couple hundred hour print project and I'm having some reoccurring issues. 

 

First - Despite adjusting the the z offset to almost air printing, my nozzles drags the print hard enough to raddle the gantry. For the most part, default settings except for combing turned off. Ironically because it would cause the nozzle to score the print. 

 

Second - One side of my print is almost perfect, while the other has gaps in layers and jagged lines. I have absolutely no idea what's going on with this.

Wow - quite the contrast.  A few things:

1) What kind of printer is this? 

2) Do you have symmetrical fans on both sides or only one side.  If two fans - are both spinning?

 

Most likely the "back" is bad where it does layer changes.  I would set all the printing speeds to be the same value - I think you are printing the infill too fast and it's underextruding and takes a while to recover on the outer shell and by the time it gets to the "front" of the print it gets back up to pressure.

Thanks for the quick reply! 

 

It's a metal version with mgn12 rails of the Anet A8,Single fan, E3D v6 (Thingiverse - BLV AM8) 

 

The grey filament is petg printed at 50mm/s.

 

The yellow filament is pla

printed at 80mm/s.

 

I don't feel like these speeds are unrealistic compared to what I've seen talked about?

 

Is there a magical cur(a)e all setting to fix this without reducing the speed?
