Assembling Your Smart Dispenser

Step 1: Mount the pressure sensor

Open the dispenser door and insert the couple with the pressure window facing the pressure sensing pin in the dispenser body.

Mounting the pressure sensor

Step 2: Attach a nozzle

To attach your nozzle to the end of the coupler, hold the couple in place with your thumb, and twist the nozzle clockwise. Tightening by hand is all you need.

It’s very important to not overtighten the nozzle!

Step 3: Secure the pressure sensor and nozzle

Close the dispenser door and secure it with the thumbscrew, tightening it clockwise.

Step 4: Insert a material

Remove the caps from both ends of your material’s cartridge and slide the cartridge into the dispenser body so it seats fully onto the coupler.

Step 5: Mount the motor plunger

Gently insert the motor plunger into the top of your material cartridge, aligning the notch on the motor body to the Voltera logo on the dispenser body. Once it bottoms out, twist the motor 90° clockwise to lock it in place.

Disassembling Your Smart Dispenser

Step 1: Remove the nozzle

To protect the nozzle, you need to remove it first. Loosen the thumbscrew by rotating it counterclockwise on the dispenser door, and then open the dispenser door. There is a black collar on the coupler. Rotate the black collar clockwise to eject the nozzle. You will feel some resistance at first, then it should turn easily and release the nozzle.

Removing the nozzle

Replace the nozzle with an orange tip cap to prevent air from entering the cartridge. Finally, close the dispenser door and secure it with the thumbscrew.

Preventing air from entering the cartridge is the key to consistent prints and the longevity of your material. Introducing air pockets to your material can cause leakage and undesirable print results.

Capping the pressure sensor

Step 2: Remove the motor plunger and material

Unlock the motor from the dispenser body by rotating the motor 90° counterclockwise. Then, gently pull the motor along with the cartridge out of the dispenser body. Cap your material cartridge and gently remove it from the motor plunger.

Replacing A Nozzle Only

Step 1: Remove the old nozzle

To remove the nozzle, loosen the thumbscrew by turning it counterclockwise on the dispenser door, and open the dispenser door. There is a black collar on the coupler. Rotate the black collar clockwise to eject the nozzle. You will feel some resistance at first, then it should turn easily releasing the nozzle.

You're now all set to continue printing.

When To Use The Nozzle Wrench

If you find that your nozzle is too difficult to remove from the pressure sensor you can use the supplied nozzle wrench to loosen it. To use the wrench, start by loosening the thumbscrew by turning it counterclockwise on the dispenser door and opening the dispenser door. Hold the pressure sensor in place with your thumb and attach the small side opening of the wrench around the nozzle's plastic collar. Gently turn the nozzle counterclockwise to loosen it, then remove the nozzle the rest of the way by hand.

Never use the nozzle wrench to tighten a nozzle onto the pressure sensor. You may damage your pressure sensor.
