Reseting Filament Useage/Length

Thanks.  I don't use a cartridge - have a zerocart but, now, with Repetier don't even need that.
Looking into programming it into the LCD Maintenance menu but it's self-study so will poke along...

Thanks.  Setting it to 0 causes compile error relating to HAL sdeeprom and, because I'm using Simplify3D, I'm hopeful of using a custom macro or an ending G/M code.  I have some macro's and M/G codes to do things and want to finish up.

My preference would be to either hit the assigned macro button to reset it or use the LCD menu (probably place the command in Maintenance, which is where the Load and UnLoad filament is...

I'm certain it will be simple - the main problem is getting the folks a Simplify to identify the command - they have the input field and boast about it but, other than the only command they show, no clue about what to use.  Reading their blog shows folks wanting to do things via this feature - but, they seem to respond only to specific command requests as opposed to publishing a list).

Been reviewing the various Repetier files to glean what's needed...

Edit - forgot to mention that I use Windows only if needed (such as to flash printer) - Arduino does not like my Mac and though it shows the board, it refuses to talk to it.  Tried several versions... Thus, want to avoid setting it in eeprom.

Well, after edit, I save then Upload.  Uploading complies it automatically before it uploads it.

As far as the implemented M206,  I'm not sure on the arguments / parameters to use for resetting filament... do you know them... what are they?

Thank you!  It works!!!!!!   Can't thank you enough

The LCD previously show 20.9m.  While connected, using Simplify command input, I sent M206 T3 P129 X0 and the accumulated filament used changed to 0.0m.   Just as I'd hoped for... I rebooted printer and it remained at 0.0m  I'm happy.

Two Example Scenario’s:

1). Print part with FFblack, pause (or stop) and clean-cut FF and change color by feeding in FFgreen without unload/load by chasing the FFblack with new FF (this is how I do mixed color parts). Set FFgreen to known amt (from paper log).
(FYI - Never had a hiccup as I pay attention when chasing FF so there are no gaps. This also works if running out of FF during a print...)

2). Print with FFblack and consumed 134m. Change to FFgreen, set new FFgreen consumed total with known amt . Next time I use FFblack, I can now re-set accumulated total  e.g., M206 T3 P129 X134.

And, of course, if the new FF is a new reel, X=0, hence, reset.

I keep a running log of FF and know what's used and what remains so this approach is just what I needed.

i own a xyz da Vinci 1.0 3d Printer. i have purchased new spools that wont fit in the cartridges. i have made a stand for the new spools. All is well there, however, when i try to reset the cartridge to print the counter goes to 0 of 240. i use an arduino mega 2560. with the corect 5v, grd, and pin 7 setup. should i use the arduino uno or can i get it with the mega. I cant see what i am doing wrong
help would be much appreciated. thanks
