Topic: E3D nozzle setting

Right guys I have just got my printer back up and running

The E3D V6 it's highly recommended from me but just need a little help to dail in the settings...

When doing circles and slots it leaves an a line shown in the pics attached it does just come of no problem but just wondering what other people's settings are

Cheers!!

Re: E3D nozzle setting

Looks like you need to up your retraction setting a hair or two

Printit Mason and Printit Horizon printers
Multiple SD2s- Bulldog XL, E3D v5/v6/Lite6, Volcano, Hobb Goblin, Titan, .9 motor, Lawsy carriages, direct Y drive, fishing line...the list goes on
Filawinder and Filastruder #1870.....worth every penny!

Good to see you got it going! My retraction settings are 7.5mm @45mm/s and I get little to no stringjng.

Re: E3D nozzle setting

Also are you using the Neustruder with the mk8? If you are your steps per mm for the extruder will need to be 130-140ish.

Re: E3D nozzle setting

7.5mm is a ludricious amount of retract, unless you have a 20ft bowden tube.

Re: E3D nozzle setting

Are you on direct drive or bowden?

I have mine set on 2mm for direct drive.  You might need to lower your temp a bit otherwise.

Its what works for me but thank you for the comment Tim. I think you may want to focus on your customer service a bit more than trolling on the forums.

I am Bowden. I run the temps high now because I got a defective MK8 gear. When I get my new one in I'm going to try to bump it down, but I'm sure I'll still be in the 5-7 region.

Re: E3D nozzle setting

I have a Bowden set up as shown attached. I have it at 7 mm retract with the standard speed on slic3r. I'm not sure what to do

That bowden coupler on the airtripper looks loose and any slop in that could negate the amount of retract you are using. When I was still running the airtripper extruder I JB welded my bowden coupler in you could try that. The goal with  bowden setup is constraint. The tighter you can make it then the better your prints will look. I have some clips for the bowden couplers that you could try printing off to help as well. I will post the link in just a bit.

That is customer service, not trolling. What specifically about my customer service do you take issue with? I'm always happy to take specific suggestions into account, PMs would be the best place in order to keep this thread on topic.

7.5mm is a great way to have PLA jams, reducing retracts is advice I have found frequently solves PLA jams on E3Dv6 hotends. Heck, the advice comes from E3D themselves, and with tens of thousands of these hotends out in the wild I would say their advice is evidence based.

In direct configurations retraction of 0.5 to 2mm is all that should be needed for ooze-free prints. We use around 0.6mm for ABS that oozes very little, and 2mm for the very floppy flexible filaments that like to ooze a great deal and need a good tug to pull back the soft filament from the melt zone. For PLA we stick with retraction settings no higher than 0.8mm.

Bowden configurations are more tricky as the amount of retraction needed is dependent on factors such as the length of tubing and the stiffness of the filament has more impact on the needed retraction. A good starting place is around the 2mm mark, which you can increase if required.

Have you printed PLA with those retracts? Long prints? (>4 hours)

If you require 7.5mm of retraction, most likely there is some other issue afoot such as a loose/not fully seated bowden connector. Retraction is frequently misunderstood, E3D's presentation is a good overview on this and many other misconceptions:

Like you said we can talk about the customer service stuff later.

As far as the PLA Jam goes I have done two 12 hour PLA prints without issue with these settings. Frankly I use ABS 99.9% of the time though, because PLA's properties make for pretty, but mechanically useless prints (for me at least). I do have batch of PLA prints coming up for engineering expo (demonstrations for the kids at the exhibit) I will do some tuning on my retraction lengths for that and see what I can come up with.

Re: E3D nozzle setting

Excellent, looking forward to hearing from you.

Re: E3D nozzle setting

I will try the settings what you suggest Browning and let you know how I get on I am only running ABS for now will be moving in to the others at a later date like the Carbon fiber and bronze....

Had anyone seen that PEEK? E3D sell it at £160 for 250g?!?!?!

Re: E3D nozzle setting

That's actually a bargain for short run polymers, especially PEEK. PEEK is expensive in raw form and difficult to extrude.
