CR-10 stock with .8 nozzle

[spankurmonkey]

Is it remotely possible to use stock CR-10 and a .8 nozzle and get decent prints? Meaning decent given its a .8 nozzle - not looking for great detail......

I've been trying but I am not good at tuning the profile.

here is a shot from my latest print using these settings (coped from a reddit) - starting to think that .6 would be the max but don't know enough about it... hoping someone can help or direct me to a few FFF profiles to try out.

Code: Select all

Material: PLA

Temperature: 237*C 

Layer height: 0.5 mm

Extrusion multiplyer: 1.02

Extrusion width: 0.8 mm

Retraction distance: 8 mm

Retraction speed: 50mm/s

Coasting distance: 1.45 mm

Wipe distance: 2 mm

Speed:

Default printing speed: 50mm/s

Outline speed: 30mm/s

Top/bottom layer speed: 35mm/s

Cooling 100% after 1st layer

No offense, but that's pretty ugly...

The last time I had a print that looked like that, it was either because the filament had absorbed moisture, or the X & Y rails needed cleaning & lubricating.

It was old filament.... I had dried it for two days ... machine is new ... other prints were fine on the .4 nozzle.

I think you may be overloading the capabilities of the print head...by printing too fast.

The lower layers look better...and once the heat has been drawn out of the head, the print quality goes.

Try a slower print....but ensure you print something large enough to replicate the head being cooled byt too high a feed rate.

It almost looks like you used 1.75mm filament, but told the slicer you has 2.85mm loaded so it wasn't squirting enough out.

Can you upload your factory file?

Also, here's someone who also had problems until he went to 35mm/sec and 15mm/sec for outlines.

This print is based upon the feedback above on the speed. I did check the filament diameter and it was set to 1.74 so I changed it to 1.75 and changed the speed to 30mm/s

I think the test cube turned out great - printed at 250% --- only bad was when the print ended the nozzle dragged... not sure what setting to change to avoid that drag at the end. Print time for this was - 1hr and 49m

Looking good!

To stop the nozzle drag, you need to add or increase retraction vertical lift ....and possibly untick Only retract when crossing open spaces (advanced tab) as well.

Now THAT print looks great.
