"a filament sensor system located below the extruder gears" vs Direct Drive Extruder on Printer?

[theschles]

Hi there, I have a Sovol SV-01 running Klipper, which has a direct-drive extruder -- and no room for a filament sensor between the printer's extruder gears and the hot-end.

When you say "The filament sensor : a filament sensor system located below the extruder gears", to which extruder are you referring?

• The printer's own extruder?
  • ...which would mean that I can't get the ERCF for my printer... -- or --
• The extruder on the ERCF?
  • ...which would mean my printer would work: Spools -> ERCF -> Filament Sensor -> Direct Drive Extruder -> Hot End

Thanks for the clarification in advance!

It's supposed to be after the toolhead extruder, however it's not required anymore if you use the "no_toolhead_sensor" branch

Apologies, I'm still learning the terminology...when you say "toolhead extruder", you're referring to the 3D printer's extruder, correct?

@theschles The toolhead is usually the thing your hotend is in, if you have DirectDrive then the Extruder is included. The whole assembly is called a tool (hence the name Toolchanger, eg. from E3D)
