Global Settings vs Extruder 1

[DivideByZero 0]

Hi,

 

When looking at a saved profile, it shows 2 tabs. Global Settings and Extruder 1 (as I have a single extruder CR10S).

 

But the settings for the profile are different.

 

For example:

 

Global Settings Layer Height = 0.2

Extruder 1 Layer Height = 0.15

 

So, how come there are two different settings stored in the one profile and yet I can only find one place to set these.

 

I have been having some major issues with stringing (to the point of destroying prints) so I am wondering if the settings are different to what I think I am using somehow.

 

Any ideas how this works? Thanks

I am not 100% sure, but I guess the global settings are from the original profile and the Extruder 1 setting from your modifications. When you create a new profile, you have an original profile as the base, then you modify some settings and save it as a new profile. But in your case, the layer height should be 0.15, because Extruder 1 settings override the global ones.

 

When you struggle with stringing, try to print cooler and check your retraction settings.

Hi,

 

I'm still not clear on where Global Settings come from and why they are different (or where you set them).

 

The reason I am curious about this in relationship to my stringing is I have tried all the usual stuff (and more) so I am wondering what is going on in the slicer now. This global settings is really what I want to understand for this question - I am not looking for stringing help in itself.

 

But, here is what I have tried for stringing (probably not in order):

 

1) Temp tower to get the ideal temp for my PLA.

2) Retraction tests

3) Retraction speed tests

4) Calibrated e-steps

5) Calibrated extrusion multiplier

6) Jerk settings

7) Travel Settings

8 ) print speed settings

9) Acceleration settings

10) Tried 2 different firmwares

11) Changed Bowden tube three times - stock, Capricorn XS, Normal PTFE

12) Changed Bowden Couplers

13) Changed part cooling fan ducts 3 times

14) Disassembled and checked my extruder - recalibrated esteps

15) Tried different brand of PLA, repeating most of the steps above

16) Checked bed levelling, in case this was creep from lower levels being too squished.

17) Changed nozzle 

 

Maybe some other stuff. 

 

Really want to understand the global settings bit next.

Can you make a screenshot of the global tab and extruder tab which shows the layer heights?

Attached you can see the Global Vs Extruder settings. I have also shown the actual profile setting and also what I can see under the Extruder setting... I must be missing something somewhere as I don't see Extruder layer Height of 0.15 set anywhere.

 

Thanks

Strange I did a test on my side and I have only one Layer Height parameter.

 

Can you try to create a new profile. Start with a default (protected) one and change the Layer Height and save it as a new profile - check it again.

I actually Had a thought about this while I was trying to sleep last night. I do have a custom start-up script which does a wipe. That's the only place I can think it's coming from. I'm out and about at the moment, but will check and confirm when I get home.

Nope - not the startup gcode. Removed my start code, restarted Cura, even tried a few profiles - the settings still didn't line up.

 

Took the "Normal" profile, which is 0.15 LH. Changed LH to 0.2 and created a new profile from the current settings.

 

Global = 0.2 (correct)

Extruder 1 = 0.15 (wrong)

 

So, where is this extruder 1 setting coming from? The profile I created, while based on the Normal template, had been changed before creation. Does this happen to you too?

[Smithy 378]

Did the same test, started from the normal profile and changed to 0.2 LH.

 

 

I have only 1 setting for Layer Height in the Global Settings tab.

Well, damn.

 

What is wrong with my Cura?

 

Just did it again, with Extra fine 0.06 and changed it to 0.1 and created a new profile.

 

Global = 0.1

Extruder1 = 0.06.

 

Seeing how I have some weird stuff going on, I would very much like to get to the bottom of this.

I am using Cura 3.6 just 4 the records.

 

I have no more idea, why it is different on your installation. Maybe try a reinstallation or it is somewhere in your printer profile which makes the difference, but I don't think so.

I'm on 3.6 too and I already reinstalled. Will try on a different pc I guess.

Downloaded a profile from Facebook last night. Imported that and it doesn't have the issue...

 

A previously downloaded profile I had from a week or so ago does have the issue.

 

Do the devs look in this forum? Someone must know what this is about. Notihng in the manual, but it must be coming from somewhere.

Only from time to time, it is better to report it at Github. There is a link in the Help menu of Cura.
