Filament config

Iamturbo1978

Hello everyone,

I'm just starting with the filament feature. I have a working load, unload, and config macros. I noticed that after a power down and restart, the filament is loaded under the tool 0, like is should, but the config does not load. with in my filament config macro, I have it set up to clear any baby stepping, then do -0.10mm baby stepping. If I unload and load the filament, the config macro runs like it should, but after power down, the config macro doesn't load. Is there something I am missing, or is there something I should be doing to make the filament config macro run after power up?

Thanks

Hi,

I just join this because I have similiar problems. In my case the filament config does not work. First it worked perfect and I used the filaments config to set up diffrent pressure advance settings but now it doesn' work any more. I don't know what changed

This is behaviour is intentional because the tool of the corresponding filament has to be selected in order for the config macro to work. See M703 for more information about how to run filament configs manually (https://reprap.org/wiki/G-code#M703:Get_Board_Type.2F_Configure_Filament).

I did add M703 in the tpost*.g file but that didn't change anything. Or do I have to put it somewhere else?

@chrishamm thank you so much for the reply. It makes total sense why not to load the config automatically. I now understand what I need to do. Thank you.

What firmware version are you using? You must use 2.02 or newer to use the M703 feature.

See https://duet3d.dozuki.com/Wiki/GCode#Section_M703_Configure_filament

@caijonas Be aware that no tool change macros are run if you select the tool in config.g or if you don't have the axes homed at the time the T-code is processed.

I added M703 to the start macro that is called in the start gcode.
I believe there is room for improvement by loading the config automatically but this works.

I Just added M703 into the start gcode of my slicer. Now it works. Thank you.
