Filament change without AMS mid-print

Several goals actually…

Education

  • Help you understand what you don’t understand
  • Encourage you to read other posts to educate you on why I was trying to not advertise this work around

Have a little fun with it

  • trying to lighten the mood
  • people like puzzles, no?
  • the quiz isn’t really meant to be difficult

But most of all, I was hoping I could get you to think.

I apologize if it missed the mark. I thought it a better approach then slinging insults like so many tend to do on this forum.

I could give you the answers if you’d like, but I was really hoping you’d take a small amount of time and try to understand what I was getting at.

I get where you are coming from. I mean, right now, when I load up some stuff in Bambu Studio I get a message that some of the ‘custom code’ has been stripped for my safety. Hopefully that will spell it out for others.

I have a similar issue where I want to print some playing cards that I made, and, you guessed it, I do not have an AMS. the print is 4 layers only, with the last 2 being black (want to have the hardest color to blend from last. But the first 2 layers have a combination of white and another color. I would want it to print the white (main filament color) first, then the other color (to reduce the color smear that white often gets.

What I don’t understand is why this can only happen with an AMS. The process is not different. It stops printing after 1 color, then dumps the old color, cleans off, pulls in the new color, then does its tower. I don’t understand why I cannot be the one to change the filament at that time.

In any case, thank you for all your efforts here.

New Bambu A1 non-AMS (bought Dec '24) user. I successfully printed two (2) different layer colors using BamBu Studio 1.10.2.76 with this method:

  1. Slice the model.
  2. In the preview screen use the layer tool and identify the layer to change color.
  3. Right-click and add a pause.
  4. Slice again, then print.
  5. When the pause is reached, printing stops and the toolhead moves off the print plate.
  6. Using the A1 on-screen filament unload/load function, swap the filament.
  7. Click Resume on the A1 on-screen menu.
  8. Rejoice!

That’s it.

@Lexi If you have a solution for this, please share - /bambulab/BambuStudio/issues/4094

gcode for Unload, Pause and then Reload

What model printer do you have?

-------------- Bambulab A1

I don’t have G-code for the A1. I have it for X1/P1.

Let me see what I can find.

Sure, Please let me know. Basically I m looking for the gcode that runs when we click unload (Logic that does performs home all axes, goes to filament cutter, cut and then pushes the filament back) and load from bambu studio or in the screen. Thank you!
