Hello everybody,
I`m needing your help.I want to print some labeled plates for my systainers. The base plate is black and the writing must be white. I made introduce a filament change in Bambu at my P1P but and the needed layer hight, the printer ignore the pause and he print like before. What is my mistake ?
Thank you

Seems like non-AMS filament change is not supported currently. I only found it out when I start a multi-color print directly on my X1CC directly on the machine there is a message: “AMS deactivated, model will be printed with the filament from the spool holder”.
What I find annoying is that there is no indication of that when you start it from the slicer 
And for sure, that even it isn’t supported…
Rather than choose a filament change at height, select Pause instead. Then when it pauses, unload the current filament and load the new one.

The printer ignore the pauses. He printed without any stop.
Worked for me, but could have been better.
The printer DID pause at the selected layer, moved the head back to the poop chute, and put up a message saying the print was paused. I closed that dialog and went to the adjustment tab.
Annoyance #1 - it had turned off the hotend, so I had to enter a new temperature.
I tapped Retract enough times to unload the filament.
Annoyance #2 - an Unload option should have been available (button was disabled)
Inserted new filament and hit Extrude a few times until I saw the new filament coming out.
Annoyance #3 - No Load option
Went back to the home screen, tapped Resume. It did a wipe and then resumed.
In the Gcode file there was this:
M623
; update layer progress
M73 L57
M991 S0 P56 ;notify layer change
; PAUSE_PRINTING
M400 U1

Has an easier way to include a pause to allow filament change been made available in the most recent version of Bambu Studio SoftFever? (currently 1.4.5, I think)
No - it’s the same as in Studio as well as PrusaSlicer. I never thought of this as difficult.

Thanks. I’ve just never been able to get that cutting lever to actually cut filament. Do you have to press it really hard? Thanks again.
You shouldn’t have to push it yourself - just hit “unload” on the control panel/display, which will cut the filament automatically. You do have to then feed the new filament in and hit the extrude button once or twice.
I suppose you CAN push the cutter lever, but yes, it requires a hard push. I don’t recommend this approach.

Now I’m confused. I read (somewhere in this forum) that the Unload button wasn’t available when the X1C is paused mid-print. I’m about to try it, but you’re saying it is available then? Thanks again, BTW.
As far as I know, it is available mid-print. But if not, then hit the “retract” button seven or eight times to free the filament from the extruder, then do the change, hitting “extrude” once or twice to engage.

Great, thanks. I’m still new to the slicing using Bambu Studio and Studio SoftFever. Can you help me find the means to insert the pause? It needs to be done post-slicing, correct?
Wait, I think I found it. I right-clicked the plus sign on the layer selection slider in Preview and selected Add Pause. Correct?
Yes, you slice first. Sadly, Bambu hasn’t added the details to their Wiki, but you can look at Color change | Prusa Knowledge Base (prusa3d.com) for the basics. After slicing, you adjust the layer slider (+) button on the right to the layer where you want the change. Right click on the (+) and select Add Pause. Repeat as needed, then click Slice again.
When the pause is reached, the toolhead will go back to the poop chute and wait for you to unload and reload the filament (see my earlier reply.) Then you hit Resume and it will pick up.

Yes, it is sad that you needed to refer me to a competitor’s Knowledge Base to help with this request. I’m disappointed that the documentation for this wonderful printer is so abysmally deficient. One case in point is the fact that searching the wiki includes results that are only accessible by administrators of the site, so the user is prompted to enter credentials that are impossible for the user to be in possession of.
I tried inserting the pause before I received your reply that included the instruction that I needed to slice again. Having not attempted to slice again, the printer did pause, but then presented a modal dialog that allowed me no access to unload the filament as you had instructed in the previous reply.
I will now try again, this time attempting to perform the operation “slice again”, and see if I have any more options at the point when the print is paused that will allow me to actually remove and add new filament. If not, then I will have to assume that this type of operation isn’t valid, and… well, I’ll cross that bridge when I come to it. Thanks again.
Through continuing the process for the test print I had already started, I was able to change filament and resume printing without having performed “slice again” after all. In the modal dialog presented at the time of the pause, there were 3 options, “Resume”, “Stop”, and “Close”. I tapped the “Close” button, and the printer stayed in “Pause” mode, allowing me to use the retract button (“▲”) to unload the current filament as you instructed. I was able to insert the new filament and press the load button (“▼”) to feed filament into the extruder, and finally to press “Resume” to allow the print to continue with the new filament. Thanks again.
Glad to hear it. Bambu Studio is openly adapted from PrusaSlicer, so a lot of the operation is similar between the two. Prusa’s description of Variable Layer Height is far better than Bambu’s.

Nice, I am going to try this with the slider and pausing. My question is this. Say I insert a pause at layer 2. Will it print layer 2 and then pause or will it pause after printing layer 1 and not print layer 2 until after I resume?
The Pause is inserted at the beginning of the layer.

It will pause when layer one is finished and before start of layer two.
