Multiple objects same build plate

Is your feature request related to a problem?

I'm trying to print something that requires 3 colors, and base plate and frame and embossed inside is a character outline in white with black pupils. I can't find any support on doing this with an Ender 3 v2. Is there a repository with this information or is it in the works?

Which printers will be beneficial to this feature?

Klipper, Marlin

Describe the solution you'd like

Configure multiple color prints on one plate and not by layer

You can enable manual filament change in printer settings.
Though it will be manual labor intensive print.

I initially thought that as well, but my Ender 3 v2 didn’t register the gcode from the slicer to stop for the change. Sent by the squirrels in a boxOn May 12, 2024, at 14:44, vgdh ***@***.***> wrote: You can enable manual filament change in printer settings.

This is not a slicer bug. Please close issue down and seek support in the discord server.

Eh... I'm not sure I agree with that. I can see the OP's expectations.
If you have 3 objects, and you've set them to 3 different filaments, then there's sort of an expectation that there'd be an automatic pause at each object change.

But when you look at the gcode there's no pause commands, no changes when changing from object to object.

But what you DO SEE is a change in extruder. There's a T2 at the change to Torus. There's a T1 and change to Sphere and a T0 at the start of Cylinder. Its changing extruders for a machine that only has ONE extruder.
If its not a bug then what would you call it?

@BiggumBuddha
What you could do... Take the gcode and run it through Notepad++, do a search & replace, and replace all the instances of Tx with a pause command. I think that's m25 but you should confirm it for your machine.

[igiannakas]

You can set pause command in the filament change gcode box in the printer settings. Also enable manual filament change so the Tx commands are not emitted.

[igiannakas]

See below pause command emitted to gcode when setup for manual filament change + the change filament g-code is PAUSE.

This is a setup issue, not a slicer bug...

[BiggumBuddha]

I would agree, except T1 isn’t a supported command on Ender machines. Not having a valid code option (in my mind) makes that a slicer bug, as the expectation is that the gcode commands are expected to work from the slicer and the slicer is compatible with the Ender series. Sent by the squirrels in a boxOn May 14, 2024, at 07:00, Ioannis Giannakas ***@***.***> wrote: See below pause command emitted to gcode when setup for manual filament change + the change filament g-code is PAUSE.

If you enable manual filament change, the Tx commands are not issued in the gcode. See my screenshot above... What you see in the screenshot is a GCODE comment ;)

[BiggumBuddha]

Right, and that was my setup before I submitted the ticket (Manual filament change enabled), and it issued the T1 command, which is ignored by Ender series. What should have been a MMU (3) print was a single with no pause for filament change with manual enabled.

Did you implement the screenshots exactly as I have them above? You need to set it to manual filament change AND type in the pause command at the filament change gcode box.

[igiannakas]

In the gcode above I don’t see a Tx command but rather the pause command where the tool changes. Implement the changes as exactly I’ve screenshotted them above. If it doesn’t work post the project file as without it I cannot see what you’re seeing…

[BiggumBuddha]

Right on. I most likely didn't, as I assumed enabling would augment the PAUSE command. I'll give it a run today, and update afterwards.
