Designed and open-sourced by K. Hart aka Hartk, the Voron SteatlhBurner Toolhead PCB is the latest version available for the NEW StealthBurner Extruder and it makes wiring the extruder toolhead easier and more serviceable for maintenance.
We are sending Hartk SB Rev2 PCB.
- fully soldered and ready to use!
- micro-fit type connector for heater and thermistor (direct compatibility with Revo and Rapido)
- support for the new RGBW LEDs
- support for the ERCF filament sensor
- support for a plug-in external chamber themistor
- input for the new 5015 blower parts cooling fan
- input for the 4010 extruder fan
- input for the round pancake motor from LDO connected on the backside
- all connectors are now JST PH 2.00mm instead of JST XH of 2.54mm (we send them along with this product so you don’t need to buy them separetly.)
Along with this product you will receive all the connectors and terminals necessary to attach this PCB to your wire harness, including:
- 1x 14 Pin 2×7 microfit female connector
- 2x 2 Pin 1×2 microfit female connector
- 1x 2 Pin 2×1 microfit female connector
- 2x 2 pin jst-ph 2.00mm female connector
- 4x 3 pin jst-ph 2.00mm female connector
- 1x 4 pin jst-ph 2.00mm female connector
- 20x molex microfit 3.0mm crimp terminals
- 20x jst-ph 2.0mm crimp terminals
This item is fully soldered and in ready condition to be used.
We sent our items in ESD anti-static bags.
Technical and Assembly information
Auxiliary Pin configuration
The aux pin can be used for a couple different things, it can be used for an X endstop on the toolhead if you are going with the umbililcal MOD, to do this you need to wire up the x endstop as shown here:
the aux pin can also be used as a header for a plugged in chamber thermistor , to do this you need to wire the thermistor up as shown here
Klicky should be connected to signal (green) and ground (black) only.
If you are a new user or it’s a fresh installation
There is a diagram to connect the StealthBurner PCB to the Bigtree Tech Octopus (click in the picture to expand):
If you are upgrading from Afterburner to StealthBurner
The New SealthBurner toolhead PCB doesn’t have a inbuilt chamber thermistor soldered at the PCB, for that reason, please remove all the config code lines at your printer.cfg. If you still like to have a chamber thermistor we recommend you to buy our external plug-in chamber thermistor.
Don’t forget that you need to recrimp everything from JST XH 2.54 to PH 2.00mm.
You need to print the new printed parts for the extruder and also carriage (still beta)
There is now a mount for the accelerometer ADXL345 inbuilt in the toolhead.
The default rail is now MGN12 with the new voron v2.4 rev2 and it’s mandatory for the CW2.
The new stealtburner needs news screws and heat inserts and also a new round pancake stepper motor.
There is also an awsome change: the RGBW leds to lighten up the nozzle and visually indicate status at front voron logo.
There are some minor changes that you need to do at your mother board, please check this comparison:
|*NEW* Hartk Stealth Burner
Hartk ERCF Toolhead PCB -> New SB PCB
Don’t recrimp anything at all. Don’t touch the black microfit 3.0 2×7 or 2×1 connector. You only need to change 2 or 3 wires on the octopus board and nothing else. Remember that there are 3 differences between the the old Hartk ERCF on the AB and the new Hartk SB board. CT changed to 5V, 5V changed to LED and XES to AUX.
At your motherboard remove the chamber thermistor connector and place it in a 5v Output (eg. any fan. check polarity).
Remove the 5v cable from it’s position and use it to control the RGB Leds (eg. J37 PB0 pin Octopus Board.)
X endstop is now “auxiliary” and probably for most users it means that is the External Chamber thermistor, move it to a thermistor input.
Make changes to your printer.cfg according this new setup.
Hartk v4.0 Toolhead PCB -> New SB PCB
You need two new cables. One of new RGBW Leds and another for the filament Sensor. If you don’t use the ERCF project or you don’t want a filament sensor just keep on moving. If you need a filament sensor please click here to buy it. At your motherboard switch the thermistor cable for the 5v Output.
