My friend ... you owe me the explanation for at least two out of the six filament changes, Cameron had in his renewed experiment.




Nice contest ....
Your turn 😉

Sorry, I don't owe you anything.

Excuse me & take my apologies.
I thought we could continue this conversation a little ironic, humorous, in a pseudo knowledge contest and joking.
I failed.My fault. sorry.

So take my excuse, forget everything and good bye

that makes sense now :).  wondered why it starts with a filament change rather than just start with white.   it is very cool to be able to do this.  Thanks again for your help ... cam (slightly less of a newbie now)

Nothing to stop you simply editing the GCODE file to remove the first (pointless) filament change.

Particularly if you will reuse GCODE file lots of times, probably not worth it for a one off.

Hello there,

Thank you for your detailed explanation and the shared file.  I compared yours to mine and for some reason I am not seeing the Extruder 2 in the top left corner, in the sliced view.

If I load the second part as a "part" and assign it to the Extruder 2, it works. But if I load it as a "modifier", then it does not...

I guess if I load it as a "part", I can setup a second filament profile and adjust the parameters in there.

Any ideas?

Not sure how you added your .3mf file... I can't add mine.

Thank you!

I have added two screen shots...one when second part is loaded as PART and one when loaded as MODIFIER.

I've had success with this method, but I wonder if folks have had success using this WITH the wipe tower too.

When I use the wipe tower, it completes the M600, I hold the squiggly spiral bit as described above, and then the extruder moves to the purge area, makes a small blob in place, and then a thick streak as it makes its X move. Some of the time, this boogery bit causes a crash the next time around whrn the nozzle hits it.

I get that it's part of purging, but I'm handling that fine with the M600. I really just want it to extrude for a while to get the new filament working well so I don't have to keep saying it's not the correct color when loading. FWIW I'm using this to print PLA support interface layers as a "soluble" (0 distance) support for PETG overhangs. It works great EXCEPT for (1) the boggery bits on the wipe tower and (2) I can't get 2 support interface layers (it's a bug). I can handle the last part, but my purging is so messy.

Other than manually editing the gcode, is there a way to keep it from making a mess on the wipe tower?

All tips appreciated!!

FWIW it's the "TOOLCHANGE LOAD" gcode I'm editing, the bold parts below are the mini blob and thick line:
