This is a PCB made for Armchair Engineering's Xol Toolhead, featuring:
One hotend cooling fan JST-XH connectors
Two part cooling fan JST-XH connectors
One heater Micro-Fit connector
One thermistor Micro-Fit connector
One Neopixel JST-XH connector
Two auxiliary JST-XH connectors
One extruder motor connector
Selectable fan voltage (5V, Alt, 24V)
Integrated mount for carriage screw
This PCB is not pre-soldered, you need to solder it yourself.
Xol Hardware Kit (for Update 2024-06-19)
Includes carriage parts, toolhead mounting hardware and optional hardware. Includes some spare screws and inserts. Note that the screws to mount the extruder are not included, as these vary depending on the specific extruder you use.
The product photo shows the original Xol Kit contents, we try to update the kits as the project progresses.
