M200 Volumetric issue

heathmanc

I'm having an issue enabling volumetric extrusion using slic3r, I've added a M200 D1.78 as you will see below, but once the print start and I issue a M200 in the console, it says it's not enabled. If I go ahead and manually input M200 D1.78 it proceeds to take that.

Volumetric extrusion is enabled/disabled separately for each GCode source. So the M200 command in your start GCode should still work, even though M200 reports that volumetric extrusion for the GCode source that you send that command from (e.g. web interface) is not enabled. The reason it is done this way is so that the extrude buttons on the web interface and PanelDue are not affected by volumetric extrusion, neither are any filament change macros you write.

Got it. Thanks for the quick response!
