Introduction
Volcano assembly is easy, and we provide most of the tools you'll need. Note, though, that you should be very careful of the following safety cautions:
- Be aware of your electronics. Don't work on your printer while it is plugged in or turned on.
- Be aware when you heat up your new hotend not to burn yourself.
-
-
Gather the following:
-
Thermistor Cartridge
-
Volcano Heater Block
-
Smaller, 1.5mm Hex Wrench
-
One of the M3 Grub Screws
-
-
-
Make sure you're looking at the side of your heater block that has little indents for wiring on it.
-
-
-
-
Screw in the grub screw until it just touches the thermistor cartridge
-
Tighten the screw by another 1/8th of a turn.
-
-
-
Before you install your heater cartridge, you should double check that you got the correct voltage cartridge. They are laser etched with their voltage, but all it is worth double-checking anyway. This process is less annoying than putting out a house fire.
-
If you have a 12v30w heater cartridge, your multimeter should read 4.8Ω
-
If you have a 24v30w heater cartridge, your multimeter should read 19.2Ω
-
Your cartridges resistance may deviate slightly from these numbers, which is fine. We're mostly interested in verifying which cartridge type you have.

Gather the following:
-
Heater Block
-
Heater Cartridge
-
The Larger, 2.5mm Hex Wrench
-
Two of the Longer, M3x10mm Screws
-
Two M3 Washers (optional)
-
-
-
Slide in the heater cartridge all the way. Depending on the exact size of your cartridge, it may protrude a little from the bottom of the block, which is fine.
-
Remember, the wires should be coming out of the top of the heater block, which is the side with the little indent.
-
-
-
Tighten the M3x15mm socket dome screws (with the M3 washers on them) with 2.5 mm hex wrench until the clamp deforms slightly.
-
You do not need to worry about over-tightening the screws; the heater cartridge is made of steel and is very tough, unlike the thermistor cartridge.
-
-
-
Tug gently on both your heater cartridge and thermistor cartridge to make sure they stay in place.
-
-
-
-
Screw in the nozzle all the way into the heater block on the side opposite the wires from your electronics. Don't worry about tightness yet.
-
Unscrew the nozzle by a 1/4 of a turn.
