SL_ST EXTRUDERRR 8 in progress

In my opinion, kinematic basing is overrated. It is weak and there is too little contact. I suggest making conical base surfaces. Almost like a collet clamp. But so that it opens into two or more parts. In this way, you can safely remove the extruder and ensure a quick tool change. As a result, each head will be supplemented with only one chiseled part, into which the extruder will be handed. Cheap, fast and reliable!
