Filament Sensor

I tested two random filament runout sensors that I had on hand. Both work just fine. It seems to me that any sensor with VCC, Ground, and Signal pins should work.

In order to get the filament sensor working, just make sure that the VCC, Ground, and Signal line up with the pins on the hotend PCB, port P7.

In order to 'mount' the sensor while it's not in use, simply glue a small magnet onto the sensor. You can then stick the sensor onto the extruder motor. You might also want to tether the sensor to the extruder cable with a piece of string.

The complete Klipper code to make this work is part of my OSS Klipper Configuration.

Aftermarket Options

These can be found for very cheap (roughly $1.5) on Aliexpress and quite a bit more on Amazon (though still very affordable). This is the one I bought. Here's another seemingly viable option.

How To Cable

You need to make your own cable. I recommend getting these JST 1.25 cables, and this XH2.54 kit. You will also need a crimping tool such as the Engineer PA-09.

Heatblock

The SV06 uses a Creality CR10 heatblock which supports MK8 threaded nozzles (including some M6 nozzles). The material is likely nickel-plated copper (needs verification).

The heatblock is mounted onto the extruder assembly using 2 x M2.5 10mm SHCS.

Please see some more relevant details here.

Aftermarket Options

Any of these heatblocks will do just fine, however, may require mounting bolts of different sizes.

Heater Cartridge

The SV06 uses a ceramic heater cartridge.

Voltage	Watts	Dimensions	Connection	Cable Length
24V	40W	6x20mm	JST PH 2.0 2-Pin	~40mm

The heater cartridge is glued into the heatblock, a heatblock that heats to 300C. Although possible, it is inadvisable, and potentially dangerous to attempt removal.

Aftermarket Options

Unfortunately, a direct, non-DIY replacement seems unlikely. It appears that no one sells heater cartridges with JST PH 2.0 2-Pin connectors.

You would have to buy a heater cartridge such as this, and crimp the appropriate connector on.

⚠️ Caveat: This is not an ordinary crimp job. The hotend assembly consumes a lot of power and is dangerously hot. Take every precaution.

Thermistor

The SV06 uses a glass-bead thermistor.

Material	Dimensions	Connection	Cable Length
Glass	2mm	JST 1.25mm 2-Pin	~40mm

As was the case with the heater cartridge, the thermistor is also glued into place, and is very unlikely to survive removal given the delicacy of the cables and composing material.
