Last time I tried printing with the raspberry pi I had only one machine to try with now I have two. Lets see if the Pi can handle two instances of AtCore and control two 3d printers at the same time. This is a follow up to AtCore takes to the pi. So please read that for more about the RPi setup. This post is in video form, please enjoy.
Since I find myself with a bit of down time. I have decided to update you all on the progress of atcore and atelier. We should hopefully be ready soon to start the process of releasing AtCore 2.0. I only have a few things I really want to get merged before I start that process. In the mean time here is what has been landed to AtCore since my last post.

It has been sometime since I’ve written about our progress with AtCore and now that I find myself with a bit of down time Its time to give you all an update. Since the end of May we have landed 32 commits from 4 contributors. I would like to first thank our newest contributor Leandro Santiago for taking time to contribute to AtCore.
Our changes include:
- C++ modernization to use more C++11 standards
- Making sure that all AtCore strings are translatable.
- Fixing our method to find plugins (a few times..)
- Adding a new emit to forward lower level messages.
- GRBL translate for some basic CNC use with this plugin
- Not checking for new devices if AtCore is connected
- Improve the PlotWidget:
- Doesn’t have a memory leak
- Let the client add and remove plots on the fly
- Improve the LogWidget:
- Reduce disk I/O
- Add info pane with basic info about the log.
- Much better regex for temperature reading.
- Clean ups for safer all around use.
- Support for most Sd card operations and a new Sd card widget.
For Atelier we have 44 commits and 3 contributors for this time and changes include:
- Adding the newer AtCore widgets and features.
- Adding a welcome panel with news and help.
- Mac os and Windows packaging improvements
- Using profile data to setup gui.
- Ask to overwrite files
- Inform of unsaved changes before printing.
- Various other small improvements
You can find our more about Atelier by reading Lays’ Post about Akademy 2018
There are way to many changes to put here in one post for these two projects since my last update. I will very quickly just go over some changes. With AtCore we now detect plugins better. Provide a more flexible deployment configuration and and have a Homebrew script for Mac in the KDE-mac tap. (log) AtCore is getting ready for a new release v2.0 this will be required to build Atelier. This will be the topic of my next post. Where plan to cover the journey and changes from AtCore 1.0 to AtCore 2.0.
Atelier has gotten the lions share of the work since the last update at least a diff a day! These include using all AtCoreWidgets for the common items shared with the test gui. Supporting drag and drop to open files. Having the 3d View tracking on the gcode files open the in editor so you can preview the open file. Improvements to the gcode editor. Quite a few more that I am not remembering all while cutting down on the code where possible and making parts leaner. (log)
It has been over a month since my last progress update. Here is what I’ve done.
AtCore will now deploy libAtCoreWidgets. Sd card support is working for repetier and marlin. I can not assure you it will work for any other firmware correctly. Command injection is now done (D11024).
Atelier Update :
General UI Improvements.
- Remove “Profiles” and “New Instance” from toolbar by default.
- Show Profile dialog upon connection attempt with no profiles created.
- Embed fallback icons with awareness of Light / Dark Theme
- Instance now get filelist on creation
- Show the print actions only if a file has been opened or printing from sd.
- Use AtCoreWidgets.
- Clean up toolbars for atcoreInstance.
- New Instance Button on tabWidget.
- Close Tabs, if more then one tab open.
- Rename Test Gui to atcore-gui
- More build switches for gui/documents and test
- Cleaner disconnects from printers
- Cleaner deployment of devel files
- Added an extruder control to the axis control
- Better checks for CONNECTING state.
- More Readable and easier to expand GCodeCommands.
Things being worked on.
A few users have asked for Sd card support and hopefully the basic version of that will be merged soon. This feature appears to be a more firmware dependent so it may take some time before each of our target firmwares has full support for SD Cards. The other feature that is being worked on is command injection. I have been thinking about adding this for a long time and I finally have a decent set of changes to support this feature in atcore. I can hear some of you out there asking about what exactly I mean by command injection is so I’ll explain. This feature will allow you to place specific commands for atcore into the gcode file. There is no need to worry about the commands breaking your gcode file since they are added in a way that makes them invisible to other hosts. You can trigger temperature changes, speed changes, pauses and more in this way. Using a few injected codes I was able to modify my test code that I print into a print that was made of abs with a tpu core. I didn’t have to touch atcore’s gui other then to resume after the auto initiated pause(s) and I can make prints with multiple colors and materials.
The Raspberry Pi3 is a small single board computer that costs around $35 (USD). It comes with a network port, wifi , bt , 4 usb ports , gpio pins , camera port , a display out, hdmi, a TRRS for analog A/V out. 1GB of ran and 4 ~1GHz armv8 cores Inside small SOC. Its storage is a microSd card they are a low cost and low power device. The Touchscreen kit is an 800×480 display that hooks to the Gpio for touch and dsi port for video. To hold our hardware is the standard touch screen enclosure that often comes with the screen if you buy it in a kit.
Most of the time it is sufficient to run Raspian the official distro that is made for the raspberry pi. raspian is a fork of debian as much like debian it has some old packages. In order to build AtCore (with the gui) you need at least qt5.8 raspian comes with 5.7. This is not a show stopper but compiling qt does take quite some time and can easily take a week if we were to build it on the rpi itself. Setting up a cross complier will save you a lot of time but even on my fastest machine it will still take some hours to build qt for the pi. I decided it would instead be faster to install a completely unsupported OS on the device. I was going to install install arch linux on the rpi. Arch is a rolling distro that ships with qt 5.10.
Arch linux on the raspberry pi is what you might call “doubly unsupported” That is that the raspberry pi foundation does not support running arch on the pi. You only get support from the arch community. Arch Linux is not officially supported on platforms other then x86_64 the rpi running on arm. Worry not for the Arch community has some forks such as archlinux-arm this is what we will be installing. Like most things arch you get some instructions. After getting the os installed its still arch so you only get a cli interface on your first boot and are left to set up the rest of the system.
For my system I installed plasma-meta , xf86-video-fbturbo-git and sddm. With those I was able to have a working plasma shell. I also installed dolphin, kate and konsole as well as the few atcore dependencies. I then added my user to the uucp group so I was able to r/w to serial devices and restarted. When all the dependencies are installed you can proceed to build atcore. Since this is arch we can simplify the building part just by using atcore-git from the aur. Im Happy to say it took only minutes and 48 seconds to build atcore-git on the rpi. I then used pacman to install the atcore-git package and it was time to see how our gui was looking on such a small screen.
At first the contents of the atcore-gui spill off the screen due to the way our docks are tabbed, however since they are docks you can just adjust them to make a quick usable interface. After adjusting the gui AtCore worked exactly the same as it does on other systems. Below you can see a picture and video.
Can do better
There is lots of room for improvement. Atcore-gui does not save any settings. You’ll need to move the docks around each time you launch the program. Atcore-gui can not automatically connect to a device on launch. Again for reasons of not saving settings This gui is of course not really made for use on a touch screen and it does seam to work good enough to use. Some non atcore changes on the system itself would be nice. A few services running on the pi would improve this over all. Mjpeg streamer or another method of streaming video from the attached camera on my printers extruder. Uploads are done via stfp that’s not always easy for everyone. The pi does not launch atcore-gui on start up . Small stuff like this could easily be adjusted. I was really just playing around to see how atcore ran on the rpi. I was very happy when this worked well.
Today I would like to announce the release of AtCore 1.0.0. This is the first stable release for AtCore. Since its the first release and we have not written a “real” client for it yet we include our test GUI. If you own a 3D Printer you are encouraged to try AtCore for at least one print job.
Using AtCore Test GUI
Using the AtCore test gui is really easy for Linux you only need to make the AppImage executable then run it, On OsX you run the .app file and for Windows run AtCoreTest.exe. To do anything in the application you must first connect to a printer. Use the connection tab in the top area left area of the window. Select your Device and Baud then click connect. If for some reason your firmware is not able to be autodetected or you wish to speed the connection up you can select your firmware from the drop down list. If you don’t know what firmware you have try using repetier. You can find more information on the Test Gui if you view its User Guide. If you are intrested in hacking on/with AtCore you may want to check the Api Docsumentation.
- The test gui’s log will show an extra set of I/O for each connect/ disconnect you have done while its running (fixed)
- If your printer does not restart upon connection with AtCore then AtCore will not send the firmware request correctly. If this affects you just select your firmware plugin from the list, or send the command M115 from the command tab.
Be sure to Report Bugs that you might find.
Release binaries below
Linux (x86_64, AppImage) – rt.click and “Save as” Make it executable.
Windows(Win7+, portable folder)
Mac OSX(osX 10.8+)
The time has finally come to release our first beta of AtCore for the general public to use. We would really like to ensure that AtCore is working with as many machines as possible so we encourage everyone who can to test AtCore and provide us with feedback on what worked and what did not. Included in this release is the Atcore Test Client a simple GUI. This is easy to use and should work well for most people. This client only for testing Atcore and we will be releaseing Atelier as our offical client at a later time.
We have support for several firmwares, but not all firmwares. If your firmware is not autodetected try selecting the “repetier” plugin. If this happens to you please let us know what firmware you have and if repetier plugin worked for your machine. AtCore’s current feature set is mostly for 3D printers but printing to any G-Code machine that uses serial should work if you have gcode sliced for the machine.
Source Package atcore-0.90.2.tar.xz
Builds comming soon.
