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.

  1. Gather the following:

    • Gather the following:

    • Thermistor Cartridge

    • Volcano Heater Block

    • Smaller, 1.5mm Hex Wrench

    • One of the M3 Grub Screws

    Edit

  2. Make sure you're looking at the side of your heater block that has little indents for wiring on it.

  3. Slide in the thermistor cartridge all the way Slide in the thermistor cartridge all the way

  4. Screw in the grub screw until it just touches the thermistor cartridge Tighten the screw by another 1/8th of a turn.

    • Screw in the grub screw until it just touches the thermistor cartridge

    • Tighten the screw by another 1/8th of a turn.

    • Do not over tighten the screw, or you will damage the thermistor cartridge. If the thermistor can't be pulled out with gentle tugging you should be fine.

  6. 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.

  7. Gather the following:

    • Gather the following:

    • Heater Block

    • Heater Cartridge

    • The Larger, 2.5mm Hex Wrench

    • Two of the Longer, M3x10mm Screws

    • Two M3 Washers (optional)

  8. 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.

  9. Tighten the M3x15mm socket dome screws (with the M3 washers on them) with 2.5 mm hex wrench until the clamp deforms slightly. If you don't have enough washers, that's fine, they just help clamp the cartridge.

    • If you don't have enough washers, that's fine, they just help clamp the cartridge.

    • 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.

    • When you eventually screw on the heater block to your heat break and heat sink, you will have to bend the heater cartridge wires down almost horizontally. This is normal. The wires are strong enough to be bent like this.

    • The screw needs to pass through a clearance hole and then into the threaded side in order to clamp the heater cartridge. Screwing directly into the threaded hole will not clamp the heater block and risk stripping the threads.

    Edit

  10. Tug gently on both your heater cartridge and thermistor cartridge to make sure they stay in place.

  11. Gather the following:

    • Gather the following:

    • Volcano Nozzle

    • Assembled Heater Block

    Edit

  12. 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. Unscrew the nozzle by a 1/4 of a turn.
