Print issues, is this still retraction?

Tef9 · 10 Feb 2019, 21:49

Yes to slicer, that was a simple one, Esteps? Do you mean steps per mm?

Best,

Andy

Phaedrux · 10 Feb 2019, 21:52

@tef9 yes. If you were using a different sized nozzle before switching to the 0.6 nozzle x the steps per mm for the extruder may be different. You may also need to adjust the filament flow factor in the slicer.

That could account for the under exteruded look of the parts.

DocTrucker · 2 Nov 2019, 04:37

What is the extruder? 1500mm/min max speed and 1500mm/sec2 acceleration seems low for a 1.5A stepper?

Judging by 419 steps per mm on the extrusion axis this is a geared extruder. Should be capable of higher speed and accelerations or these values will restrict the effectiveness of the retractions.

As others say though, it appears under extruded and occasional PID tunes are worth while. I will now go read up on autotuning as I tend to do it with filament in the hotend!

Edit: Just seen standard shipment for the Tevo LM is an E3D Titan. dc42 runs with them so may be able to pull acceleration and jerk settings from his recommendations in posts on this forum.

DocTrucker · 2 Nov 2019, 04:42

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

Tef9 · 11 Feb 2019, 21:34

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 · 12 Feb 2019, 08:22

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

Wyvern · 2 Dec 2019, 17:10

@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 · 12 Feb 2019, 20:48

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

Best,

Andy

Phaedrux · 12 Feb 2019, 20:57

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

Tef9 · 2 Dec 2019, 21:30

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

Phaedrux · 12 Feb 2019, 21:32

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.
