Cubex Trio 3D Printer


Preparing Your Print

  • Familiarize yourself with Simplify3D.
  • In Simplify3D add the "CubeX Trio ..." FFF Profile that matches the material you are using. The "Default" Fused Filament Fabrication (FFF) Profile will not work.
  • Adjust the FFF Profile for your print only. Please do not click "Update Profile" nor "Save As New". If you want to keep your particular modified FFF Profile, save your print project (Simplify3D calls it a "Factory").
  • Always print with a raft! The bed is usable but needs some minor repairs before it can be precisely leveled and surfaced. Do not attempt to level the bed nor "enhance" the bed surface with glue, hairspray, motor oil, or any other technique/substance.
  • Click "Prepare To Print"
  • Insert a properly formatted (FAT32) flash drive into the computer.
  • Click "Save Toolpaths to Disk"
  • Select the flash drive from the dialog box and then click "Save".
  • Wait patiently. With extremely complex/big prints it may take 10-15 minutes to finish saving. When this happens Simplify3D will go to "Not Responding". This is expected behavior for Simplify3D.

Preparing the Printer

  • Inspect the printer for any obvious damage.
  • Remove dust from the print bed.
  • Because it is loose, Carefully Insert the FAT32 flash drive with the .bfb file into the printer.
  • Until repairs are complete, it is highly recommended that you check the Z-Gap before you print. Use the arrow buttons to go right in the menu until you see the "Z-gap" button. Wait until the machine stops completely. Examine the gap between the head and the bed. It should be about the thickness of a piece of paper (or maybe two). There are arrows to adjust the Z-Gap up and down on the right side of the screen. If you have to change it, it will ask you if you want to save the new setting upon exit, and say yes.


  • All the way to the left in the menu, select "Print", and select your .bfb file. It will always automatically show the newest .bfb file on the drive, if that is not what you want, you need to use the arrows to select a different one.
  • A progress bar will show up and the printer will pause as it checks and simulates the .bfb file. Let it complete this. The printer will start moving at the end.
  • Let it print. This printer is unlike our other printers. Don't mistake unfamiliar printer behaviors with printer malfunction.
  • If you notice problems with the print itself you can cancel, of course. That being said, if the first layer sticks, your print will most likely complete.
  • The bed will lower all the way to the bottom when it is done.
  • Wait for your print AND the bed to cool to room temperature.

Removing Your Item From The Bed

  • Again, wait for your print AND the bed to cool to room temperature. Unlike most printer beds, prints tend to stick too well. Attempting to remove the print from the bed too soon is very frustrating. If you think you need a scraper, then you probably haven't waited long enough.
  • In the event that the part still won't release from the bed, take the bed gently out (you don't have to unscrew anything, just lift). There are three orange vibration dampeners (ear plugs) under the bed. Note their locations so that you can replace them when you put the bed back. Gently set the bed on a table and gently remove your print with a plastic spatula or your fingers.
  • When replacing the bed, make sure that the three vibration dampeners are replaced and metal circle is pointed to the front of the printer, and fits into the corresponding hole in the printer plate.

Changing Filament

  • Changing filament is complicated because there are menu steps that have to be ignored because of the filament encoder. Until we document this more completely, ask Kira, Rob Ristroph, or Jonathan Taylor for help changing the filament.

Printing With More Than One Color

  • Until further notice, DON'T.

Pending Repairs

  • One of the slots of the print bed has detached making the able to move and rendering the front stabilizing bar useless. We still have the slot. Rob is going to acquire an appropriate adhesive to reattach the slot.
  • There are several places where cable management needs to be corrected or re-implemented.
  • Restore the screws and components *that are still needed*.


  • Several screws and bolts are removed. Parts that have been removed from the printer are in the plastic toolkit next to the printer.
  • The voltage on the first extruder driver only has been changed from 1.1V to 1.68V per CubeX Set Voltage, including the addition of a heat-sink on the driver chip.
  • Applied blue tape to bed to give it a consistent surface and to *reduce* bed adhesion because the surface of the bed is in very bad condition.
  • Feed modifications:
    • Removed feeder tube guide.
    • Covered the feed holes of extruder 2 and 3 with masking tape to protect them from debris.
    • Installed filament directly into the feed hole for extruder 1, bypassing the feeder tube completely.
    • Added a filament dust filter but no lubricant.

This Cubex Trio is a first-generation Cubex donated by ContainerBlox of Blanco, Texas. Kira Wox did all the work to get it working and usable, and she is the best person to talk to if you have questions, or if you have a Cubex you are trying to get working.

Printer Activity Log

Date Event
2017-04-12 Discovered filament not properly removed from printer. Suspect that the spool fell off the table, snapping it off.
2017-04-12 The print tip and extruder were in a condition where there was unmelted filament past the exdruder gear. Removed the print tip and extracted the piece of filament past the gear. Replaced the tip.
2017-04-12 Tightened left Y-axis belt.
2017-04-12 Installed brand-new, factory sealed, blue, Hatchbox PLA and added new FFF settings to Simplify3D.
2017-04-13 Successful 17h 21m print. Simplify3D time estimate: 12 hours 38 minutes. Notable areas for improvement: Z layer consistency. Bit of stringy bridging trouble on long spans.
2017-04-13 Successful print of calibrationbridge1.stl . 21 minutes. Simplify3D estimate 15mins . Droopy middle that planed out as layers increased.
