tfree1.g is being ignored
-
I have a very simple tfree1.g. I have a y joiner on a single nozzle hotend and want to pull out filament 100mm, the push in 100mm of the other filament when needed. I can get it to handle one extruder at a time, but when it come to tool changes, my macros are completely ignored. It seems to do a normal retraction rather than a normal retract followed by tfree1.g or tfree0.g.
Weirdly, if I just run the macros in the webui manually, they work fine.

I'm sure its obvious, but I cannot find what's going wrong. It just wants to jam filament together rather than pull one completely out and put the other completely in.

This is just a guess, but can you try adding some M400 commands to your macros?

Where in the macros would be helpful? Doesn't it normally complete a line before acting on the next one?
-
At the start of the macro? Like I said, it's more a guess.

I did some more playing around to get the behavior of this setup closer to that of the gcode the original creator's generator puts out. I had to guess and check the extrusion lengths, speeds, and replace some weird wiggle thing with dwell time, but it's kind of working now.
I can't call it a success though. The part it pulls out of the hotend has a wider diameter tip than the rest of the filament so when it goes to push it back in, it gets stuck. From what I can tell, its because I'm using an all metal hotend and there's nothing narrow inside to scrape it off on.

I think the prusa MMU was having similar issues with tip diameter, maybe look into how they were dealing with it.
