Full conventional

The whole toolhead is functionally a tool with a basic carriage being coupled to the belt. Each tool carries its own extruder motor, gears, fans, heat break and sometimes a toolhead board. The oldest type of 3D printer toolchanger.

Pros

• Uses close to standard toolheads.
• Failure modes are straightforward.
• Tools are self-contained, so one can be built or debugged on its own.
• Nothing is shared between tools, so a fault stays in one tool.

Cons

• A tool costs a whole toolhead — costly.
• Kinematic mount carries a large amount of weight and must be rigid.
• Most parts per tool to keep calibrated.
