Cura filament change script not working with this firmware #867

I have tried to utilise Cura's filament change script with this firmware but the printer doesnt seem to pause at all when it reaches to layer height for change. I suspect it has something to do with the nozzle park or advanced pause sections of the firmware not being enabled? I have yet to look at the source code myself.

Works great for me. Just used it 2 days ago for a 35 hour print that involved 6 filament changes

Apologies if this is not the right place for this, but I wanted to ask you something -

I just flashed the latest version of this firmware and tried a print with the filament change script yesterday, and the M600 flow works perfectly...until once it started going back to printing it just retracted a significant amount of filament, essentially failing the print. Not sure what happened there? Could you help me figure out what the problem was?

Here's the M600 command in the gcode -

M600 E30.00 L300.00 X0.00 Y0.00 ; Generated by FilamentChange plugin
;LAYER:63

If you're using the 1.3.2 pre-compiled FW you may be having the same issue I had: #714

This actually pushed me to start self-compiling and now I'm obsessed!

I've been avoiding it so far, but I guess the time has come... Thank you for pointing me in the right direction! It seems like you had the same kind of questions I did.

Enjoy! A recently added benefit of Jyers Patreon is an Auto-Compile service for use with your custom config files. I haven't used it, yet, but I see where it could be a good way to get some confidence and overcome this filament change issue in the meantime.

Like I just said... my 6 filament swaps worked great. The last one happened 10 layers too early, so I had to do a manual swap later in the print. But That was on me, not the firmware or the slicer. I will say that I didn't change any of the default settings in Config.h centered around retraction or purge lengths. So after interesting the new filament it extruded something like 300mm because that's technically what I told it to do. On later swaps I manually disengaged the extruder once the flow was clean. But in all, it worked exactly as it should

Some places I made changes in my compile work
configuration_h

  #ifdef FILAMENT_RUNOUT_DISTANCE_MM

I really didn't think I would use it. Ive compiled my own firmware for months. But its saved me a lot of the headache of loading new source every time something little changes. And, it gave me multiple versions of firmware to use while I was tinkering with my filament runout system. But to top it off, its the least I can do to let Jyers know his work is appreciated!

@smooreace My apologies for the confusion! I should've @'ed vjFaLk as I was answering his questions within this discussion.

It's probably more my fault @embraceentropy ... I'm following this via email, so I don't really see the conversation threaded like it is when viewed on GitHub.
