An App To Transfer Files To The FlashForge Adventurer Or Monoprice Voxel — August 26, 2020

An App To Transfer Files To The FlashForge Adventurer Or Monoprice Voxel

A little while back I wrote about how to use Cura with the Monoprice Voxel / FlashForge Adventurer 3, in that article I discussed how to create a printer profile and slice your models to produce a G-Code file. However, without using the bundled FlashPrint software, it was not possible to transfer the file over the network – instead needing to use a USB flash drive.

I wanted a lightweight app I could use to transfer files to my printer, so I’ve spent the last few weeks I’ve been building Adventurer Client to do just that. I wanted to use it as an opportunity to learn some new frameworks / technologies and I had a lot of fun building it. I thought it would be useful for other FlashForge & Monoprice users too, so now I’m ready to share it with you all.

Using Adventurer Client, you can connect to the printer, see its state and transfer already sliced gcode files to the printer.

Printer Compatibility

I’ve tested this with a Monoproce Voxel, which is a rebranded FlashFordge Adventure 3,  I believe this will work with other FlashFordge Printers too, but I don’t have access to any to test this. If you try the app with your printer and it works (or does not) please let me know 🙂.

Getting the App

Windows 10

If you’re running Windows 10, the easiest way to get the app is to instal it from the Microsoft Store here.

Windows 7, 8 & 8.1

To install the app on older versions of Windows download the installer (AdventurerClient-win.exe) from the lastest release here.

MacOS

To install the app on older versions of Windows download the macOS dmg (AdventurerClient-mac.dmg) from the lastest release here.

“Adventurer Client” cannot be opened because the developer cannot be verified.

Unfortunately, Apple requires that software running on macOS be signed and notarized so that they can verify its identity. Doing this would require me to buy an Apple Developer license which is quite expensive. Therefore, for the time being, the app is distributed unsigned (if I buy a developer license later on, I’ll submit this to the App Sotre). To run the app you need to perform the following steps, for the first run only.

  1. Double click on “Adventurer Client”
  2. At the “Adventurer Client” cannot be opened because the developer cannot be verified. message, click cancel
  3. Right click on the app and click open
  4. At the macOS cannot verify the developer of “Adventurer Client”. Are you sure you want to open it? message, click Open

Tech Details

I’ve published the app’s source under the MIT license on my GitHub. In order to easily support running on both Windows and Mac, it is implemented as an Angular app in an Electron wrapper. I was larning a lot about these technologies as I went, so if there are things that seem odd, your feedback (or pull requests) would be warmly welcomed.

Feedback

I this app is useful to some people, I plan on continueinf to tinker with it over time. If you have any feedback or suggestions, drop me a comment or a tweet on Twitter.

Using the Monoprice Voxel (FlashForge Adventure 3) With Ultimaker Cura — January 12, 2020

Using the Monoprice Voxel (FlashForge Adventure 3) With Ultimaker Cura

Recently I bought a Monoprice Voxel (a rebranded FlashForge Adventurer 3) 3D printer, and I’ve spent the last couple of weeks getting to grips with it. I’m very impressed – it works well and I’ve had a lot of fun building parts of my projects.

One interesting this about the printer is that it comes with its own slicing software called FlashPrint. This seems to work quite well, slicing all the models I threw at it and sending them to the printer. However, I was curious if it was possible to use the printer with the Ultimaker Cura slicer, which has some more advanced features and is supported more widely by the community.

I did a load of research and found some interesting topics on reddit and Ultimaker forum, I also examined the .gx files produced by FlashPrint and thoes sent to the printer by PolarCloud. I’ve gathered all this together into a this guide for using Cura, but it stands on the shoulders of a whole bunch of other people in the community, so thanks to those people you really helped me figure all this out.

Disclaimer

Every model I have printed in this way has worked well and I am very pleased. However, follow this guide at your own risk – If something bad happens to your printer, on your own head be it.

Observations

FlashPrint and the printer appear to use a custom file format for printing – .gx. This is identical to the .g file used by other printers but with some additional metadata at the top. I suspect this is the image of the model that’s shown while printing, as well as the print time estimation.

The printer is perfectly happy to print .gcode files, provided the file extension is changed to .g first. While printing a .g file the time estimation on the printer screen does not count down the remaining time, it counts up the elapsed time. Also instead of a small image of the model being shown, a generic icon is displayed.

Getting Cura

Firstly, you need to install the latest version of Cura from the Ulimaker website.

Monitoring My Indoor Air Quality — November 29, 2019

Monitoring My Indoor Air Quality

In my last post I mentioned that I also wanted my info display to show the current indoor temperature, read from the air quality monitor that I made. I built the air quality monitor a couple of years ago – it was my first experience playing with an Arduino and was a lot of fun (interspersed with moments of utterly frustrating confusion). I thought I’d put together a quick intro to what it does and how I made it.

Why Build An Air Quality Monitor?

I saw an advert for an attractive little box that you put on a shelf that monitors the air quality in your room. It has an app to view the data and send you push notifications if it the air was too unhealthy. I loved the idea – I’m a big tracker of data (I once had to log of every single ingredient of every single product I ate for an entire year) and thought it would be really interesting to find out what my environment in my house is like.

I considered buying it… I really did. Then I decided I could totally build my own. I started by buying some sensors:

Building an eInk Info Display For My Living Room — November 3, 2019

Building an eInk Info Display For My Living Room

Like a lot of Londoners, my trip to and from work involves moving between a few different trains, any of which could be delayed and cause me to be late to work. Or worse – late home. As checked the tube status on my phone over breakfast one morning, I realised that it would be super useful to have some kind of display in my living room allowing me to see at a glance how my commute is looking before I set off, so I can go a different way if needed.

There are a few options to create a display like this – I could re-purpose a tablet or phone in the technology graveyard drawer, writing a quick and dirty app to run on it. But where would the fun in that be? Sure, it would work but I wanted to learn something along the way. I decided to use a Raspberry Pi and a display of some kind, but if its going to live in my house, it needs to be pretty.

I ordered the Primoroni Inky wHAT – an eInk display with all the headers to screw it directly onto a Raspberry PI. It even has Python library for displaying stuff. I went for the two-colour red/black model; I thought I could use the red mode to make any tube status issues stand out.

Features

As soon as I’d ordered the screen, I started thinking about what I would use it for. I came up with a few things I wanted to do:

  • Display the current tube status of the most useful tube lines
  • Display the current weather / temperature outside from DarkSky
  • Show the current indoor temperature, pulled from my Air Quality Monitor (I built this a couple of years back, I might cover it in a later post)
  • Display some kind of indication that central heating is on or off
  • Show the time

I drew this little diagram to get started:

Implementation

APIs

Ever the software engineering project, the first task was to investigate the APIs to give me the data I wanted.
