Prime tower for first layer

[YUVL 0]

Hello. When printing with multiple extruders, the Prime tower starts working from the second layer. If there is an extruder change on the first layer, the prime tower will ignore the change. Is there a way to make it work from the first layer?

Could you please provide an example project file that shows this behaviour? Do File->Save and attach the .3mf file to this thread. Thanks.

Here is the 3mf file of my project

AY 1_2 extruder kulon.3mf

[burtoogle 513]

Sorry, that file is almost completely empty. It contains no model or settings. Load your project into Cura and do File->Save.

Yes, my mistake, I'm sorry

Err, that file has the settings but no models! 3rd time lucky?

It is clear that if you open g-code, then saving does not work. Created a new project. I hope everything is right now

The morning did not work out. This time I forgot to set the size of the prime tower. Corrected in the new file

Thanks for the file, yes, I can see what you mean. I don't know if there is a workaround for that in UM Cura but my Cura builds have a setting to prime all the extruders on the first layer. Here I am only displaying the extruder 2 lines and you can see the center of the prime tower is extruder 2 not 1.

 

 

If you wish to try my Cura, you can find the builds at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

 

Please read the README.md file there before using.

Yes, the center of the tower is extruder 1, but when printing, it turns out that the prime tower is filled from extruder 1, then it switches to extruder 2 and after printing a couple of border lines, letter parts printing starts

Thank you so much. It works now. Installed version of Cura-mb-master-win64-20200721. The parameter "prime all extruders on the initial layer" helped.

[burtoogle 513]

Good!

Hi @burtoogle,

 

I've had the same problem as OP and just downloaded the current release of your cura fork from https://github.com/smartavionics/Cura/releases. (Cura-mb-master-win64-20201121.exe)

 

However, the new prime tower settings don't show up. Am I missing something?

1) In the left image in your post above - just below the tabs to select extruder 1 or 2 there is a "search settings" box.  What happens if you enter "tower" in that box?  Personally I don't use the "settings visibility" feature as this is ignored when using the search box anyway.

 

2) I have an older version of "cura-mb" and it works fine for me.

 

3) Which setting exactly do you care about - please pick one as maybe the same one you care about is missing for me and I didn't notice.  I have at least one tower feature you don't seem to have: "circular prime tower".

 

4) Please save your project "file" "save..." so we can compare apples to apples - it could be something in your printer (aka machine) settings - I'm pretty sure it's possible to make settings disappear using your machine json file also.
