Hi all

which connection pins should I use for using a switching extruder?

Kind regards

Steve

Toggle extrusion? This motherboard only supports single extrusion

countcobolt commented 2 years ago

A toggling extrusion does not need a second connector, but uses a small servo to toggle which filament is being fed. You only need 1 extruder (which we have connections for) and through some printed parts, it selects which material is feeding as the servo will push either one or the other part. This is part of the stock marlin firmware. The question is, is there a connector I can use to connect a small servo to?

Kind regards
