Tool-Head PCB for Voron Afterburner (V4.0)

Clean up the wiring harness for your Voron Afterburner by using this Tool-Head PCB (designed by hartk#1213).

Warning: do not use with fans set to voltages lower than 24V. The PCB is using a common supply rail which will supply fans (and feed back to the controller board) 24V, whatever you set as fan voltage on the controller board! If you want to use lower voltage fans go for the V3.rabbit variant

The product is fully assembled (PCB with SMDs and other discrete components and connectors soldered on) and the cable loom connector with crimp terminals (fully assembled variant) or it comes PCB only (with all SMD parts assembled).

The board design includes:

One BAT85 Diode for the ABL probe
An indicator LED to show when the hotend is active
Several 2/3/4 pin headers for most components on the toolhead
One 2 Pin Microfit 3.0 for the heater (incl. the fitting counterpart connector)
One 0402 pkg thermistor (chamber temperature sensor)
One 14 Pin Microfit 3.0 for the main wiring loom back to the MCU (incl. the fitting counterpart connector)

The board was designed to make wiring the toolhead a bit easier. As a result it is helping to reduce the amount of crimping contacts needed and to clean up the cable harness.

The board has provisions for the X endstop, which makes it compatible with the Voron V1, V2, and Switchwire

The STL for the 3D mount is available on GitHub.

Here you can also find an improved version of the cover plate (it seems to be working better than the original HartK one).

You can find more infos on the Toolhead PCB on its project page on GitHub.
