Build in Print Server & New Web Interface
The A2-FU and A4-FU now feature a built in print server with ample g-code and timelapse storage. This print server enables our new modern, user friendly, customizable web UI. It also allows for macro creation, allowing you to automate procedures and even create your own powerful g-code scripts using the Jinja2 programming language.

Automatic Mesh Bed Leveling
Using a new touch sensor mounted on the print head, the A2-FU and A4-FU now feature automated mesh bed leveling. This enables direct bed printing with ease, creating serious time savings on large parts by skipping the raft. Each upgrade also comes free with a magnetic G10 build plate, which is ideal for printing large flat parts directly onto the build plate.
All new 5 inch Touch Screen Controls
Gone are the days of the scroll wheel and character matrix LCD, jump into the 21st century with a modern touch screen interface. This screen provides a significantly improved user experience, intuitive controls, a customizable interface and real time print controls. All printer functions are accessible from this screen.

Input Shaping comes to the A4-FU and A2-FU
By mounting an accelerometer on the print head, and enabled by our new Klipper firmware, we've added input shaping and resonance compensation to our upgraded printers. This allows us to print at higher speeds while simultaneously achieving higher print speeds.

Have An Older System To Upgrade?
If you have an older industrial printer gather gathering dust in a corner, why not upgrade and refurbish it instead of getting an entirely new system? OnAdditive is looking for new projects, so reach out if you've got something interesting!
