Comprehensive Flux Delta Setup and Guide

The directions that come with the Flux are definitely a bit of a beta directions. They are good, but some things have changed/evolved since they first had them printed. Here’s some directions I wrote up for another post, but wanted to put them in one spot.

These are designed for optimized setup, but are unofficial and not supported by the Flux team. These are based on my experiences and the experiences of other users. I’ll update these as things change or with feedback.

Before the flux arrives

  1. Install Flux Studio -
    • You may want to try the “Stable” version at first, but “Latest” may have some useful fixes

Once you get everything open

  1. Plug in the power
  • Plug in the USB drive only (don’t plug in anything else)
  • Unplug and replug the power - Only way to reboot device
  • Let the firmware upgrade. Do the next steps while that’s happening. (Should take about 3-5 minutes)
  • Connect the filament tube with bushings to the extruder
  • Cut your filament tip at a 45 degree angle to sharpen it to a point
  • Feed the spool filament through the other filament tube like this -
  • Dip each metal rod ball (both ends) in the metal lubricant, and attach to the outside and the extruder
  • Rub 2 coats of the glue stick on the UNPRINTED (without the grid) side the metal plate. Just make sure to get the center area unless you’re doing a large print. It’s recommended to let each coat dry.

Once the firmware is upgraded

  1. Boot up Flux Studio
  • Connect the computer with the micro USB cable
  • Run through the setup tutorial, including loading the filament
  • Print the tutorial item, or the item you want.

Once you’ve printed a few models, or earlier

  1. Update the firmware on the toolheads. You’ll have to do the extruder and laser toolheads seperately.

Using the laser engraver


A lot of other people have probably ran across the problem you’re having already. Many problems are problems people with any 3D Printer would have, but some are specific to the Flux Delta.


This is a fantastic set of set-up instructions @Milkdog! Thanks for posting this, I’m sure it will definitely come in handy for those still waiting! I wonder if we can get this “pinned” to the top of the forum? It’d be nice to have a couple of customer mod/admins now to help with stuff like this. I wonder if TeamFlux will allow this?

My flux delta arrived earlier in the week and only today have I opened the box. Of course, I forgot that I had these comprehensive instructions on my phone and just winged it by my faulty memory. Even with that handicap, I was able to print. I could not find the lubricating stickers, but have noted that there are six points around the perimeter that appear to have black plastic label material that is reasonably slippery. It may be that these are now installed prior to shipping.

Hello. I just got my FLUX in the mail a couple days ago. Now I’m trying to install the new firmware through FLUX Studios. But its taking a really long time. So I was wondering if you could tell me how long it took for you to update? Thanks.

I used the flash drive method. You download the file, copy it to the root of a flash drive, rename it as directed. With the device powered on, insert the flash drive. Power down the Flux Delta by removing the power cord, pause to reflect on what an attractive bit of engineering you are viewing, then plug in the power cord.

The Flux logo will illuminate white, then flash white and red, then return to either steady white or flashing white, I can’t recall.

Because part of the firmware update involves improved (or corrected) wifi connectivity, the flash drive will be the far more reliable method.


I had an issue where I thought it was taking a long time, but actually wasn’t working.

When you plug in the USB, make SURE all that’s plugged in is the power, i.e. the cable connecting the flux to a computer should not be plugged in either. Once I made sure that just the thumb drive and power supply were plugged in it worked in ~3-5 minutes IIRC.

I’ve added some notes for using the laser engraver. Let me know if you have any updates/comments.


@fred_dot_u Yeah I used the USB method & it finished updating in about 5 minutes. Thanks. :slight_smile:

Being that it’s been a few months since I setup my Flux, and I know that the product delivered has changed. What changes would people recommend to the guide?

A mention of the toolhead update process couldn’t hurt. You could also add a line about checking the shipping box for the lubricant stickers before recycling it.

Is it worth mentioning the Wifi capabilities of the stock setup in case people are banging their head into the desk trying to get a 5G network to connect?

I’m overdue for reconnecting my laser module and doing some engraving… Do the newest updates require the aluminum foil safety bypass anymore?

Awesome work, as always!

Please add a comment about cutting the filament into a sharp point before loading it. It is mentioned, but I suspect people don’t necessarily pay enough attention to it as I have seen a few occasions where people have had a problem loading filament and subsequently solved that by sharpening the point.


Great Directions, Milkdog. I would also suggest as part of the “Setup Directions”, for them to remember to use the 2nd plastic tube for the filament feeder and to also print out the " " Universal Filter.

Those 2 things made huge a huge impact on my printing without having all that “click, click sound” and bad prints.

Also, if they can, purchase the magnetic micro usb adapter (®-Premium-Magnetic-Detachable-Motorola/dp/B01009NQGK ). BE EXTREMELY CAREFUL because it is know to break off.

I believe that would be a full Setup “NOOB” instruction.

Updated the guide with comments from other users and my own experiences, as well as added some troubleshooting help links.


This is a great guide that I followed as best as I could.


I need photos

The finished setup should look like this?

Both the data cable and the filament tube at the rear of the machine?

How does the Filament tube inside the top of the machine attach to like in the photo on :

I get the feeling that most posters on here have at least one 3D printer.

I find the lack of photos or pictures difficult to work with.

Nope. This is my first 3D printer, or even anything like this, and I’m the one that wrote it.

You can face the machine any direction you want, but the filament tube and data cable can only really go one way.

As for the filament tub inside, it just kind of sits there. It doesn’t actually attach to anything.

If you want to take some photos of the process, I’ll gladly add them to the guide.

Thanks for the reply.

Sorry for my ill informed assumptions.

Any advice on how to get the iPhone software to recognize my printer? It use to work but when I had to replace my phone, it no longer sees the printer on my app.

The iPhone does not connect to the printer. It connects to the flux cloud. Your printer needs to be connected to the cloud through the desktop software.
