Stage 08: First Print

Install the Dry Box Platform to the left side of the frame with M5 x 6mm bolts and M5 T-Nuts.

Each Drybox should come with these set of parts.

The rubber grommets can be pressed into the holes in the lid and side of the drybox.

Fit a bearing onto each end of the metal shafts, then place the assembled shafts into the drybox.

Pull the battery tab from the humidity sensor to switch it on, then place it into its slot inside the drybox.

The DryBoxes can be loaded with filament spools and placed onto the shelf.

If you do not have the Dry Box upgrade you can use the regular spool holders.

3D Printed Spool Holder Cover (2-part)

It can be mounted with:

M5 x 100mm Bolt

M5 Penny Washer

M5 T-Nut

With the wiring and hardware checks completed you can push the PTFE filament tubes in through the couplings on the bottoms of the electronics box as shown.

The tubing can either be pushed directly into the box or be cut closer to the electronics box to make feeding easier.

Select the first print head PH1. Use the FRONT macro to bring it forward.

Feed filament in through the PTFE tube and insert it into the extruder - push it in about an inch so that it makes contact with the gear teeth.

The extruder should automatically heat up and load the filament when ready.

This button on the print head will unload the filament.

This is the tensioning lever, it has three levels:

To the left: Lowest tension, good for flexible filaments.

In the middle: Medium tension, good for most filaments like PLA/ABS

To the right: Highest tension, good for hard filaments like PC

We currently support the following Slicers:

ORCA Slicer

ORCA Slicer Profiles

PRUSA Slicer

PRUSA Slicer Profiles

ORCA Slicer

If you are installing for the first time on Mac open the software first before adding the profiles.

See the Read me file here.

PRUSA Slicer

Go to File -> Import -> Import Config Bundle...

We suggest first printing with one print head to make sure everything is setup correctly before jumping into a multi material print.

Import in a model and slice it. Then hit print and you should be able to upload it directly to the printer for printing.

Troubleshoot the network connection here if needed.

Although the bed is physically tapped the offset may need slight adjustment the first time.

If the first layer is too high decrease the tap_adjust_z value in eddy.cfg. And vice versa if too low. This value can be negative.

The multi-part benchy we're printing can be found here.

Load the model and assign a print head to each section.

Orca Slicer

Prusa Slicer

Keep the wipe tower close and to the left of your model.

Hit slice and print when ready.

Note, the screenshots are from the ProForge 300 however the concept is the same.

There are numerous resources available online that provide detailed guidance on using PRUSA and ORCA Slicer to set up various aspects of a print. We encourage you to explore them for further information.

Owning a Tool Changer 3D Printer unlocks new ways to print, we recommend trying some of the following:

Multi-material printing: Print different filament types in one job (e.g. TPU for gaskets, PLA for structure).

Larger Nozzle for Infill: Print faster and stronger by using a bigger nozzle for infill while preserving detail with a smaller one on the outer walls.

Dedicated support material nozzle: Use a separate head for soluble supports (e.g. PVA, HIPS) without contaminating primary nozzles.

Congratulations you're all set up to go!
