Print issues, is this still retraction?

DocTrucker

I've not used a delta but those acceleration settings seem conservative on the other axis too.

Tef9

Hello,

Thank you for all the replys - so far I have :

Updated the values for acceleration etc..
Tuned the H1 heater and added the M307 to the config.g
Worked out the steps per and changed it as required in the config.g

By printing the same part there is a greater density, also the filament is not...shiny when printed? The print on the right is the new print, the print on the left is the same as yesterday.

Could this be temperature or retraction?

A 0.6 volcano is going to drool quite a bit, but it looks quite extreme in the photo. Is retraction even turned on in the slicer? Are you using combing? What slicer are you using?

Tef9

Hi,

I am using Slic3r, I did have retraction set there but it seemed to make more mischief than expected. Should it be set in both firmware and slicer? I can up the firmware setting and try that.

Best,

Andy

@tef9 said in Print issues, is this still retraction?:

M350 X32 Y32 Z32 I1

This does not work on the Duet ethernet. It says so in the Gcode documentation

@phaedrux
I used a .6 volcano exclusively for a couple months and probably 15 lbs of filament.

I found fast retractions work better around 70mm/s, I really didn't have much of a dribbling issue- this was on a stupid ramps board too.

I also never used combing and still don't, I just retract on layer change.

Tef9

I'm still stumped and get lines across the part...does the firmware retraction not work?

Best,

Andy

Phaedrux

For firmware retraction to work it has to be enabled in the slicer. It varies between the slicers on how to do this.

Tef9

Opps, did not know that, thought it "just did it" when retracting.
So now things are looking better

Edit, does the firmware limit the retraction? If you have firmware set to 4mm is that the most you can retract?

Best,

Andy

You can configure retraction completely with the M207 command

https://duet3d.dozuki.com/Wiki/GCode#Section_M207_Set_retract_length

You might find this helpful for tuning, especially if you have a PanelDue.
