FELIX Automatic Calibration System

A perfect print, begins with a proper calibrated machine. Printer calibration is done fully automatically for you! Start printing with the least amount of effort.

The FELIX Pro 2 calibrates:

  • Bed to Nozzle distance.

    To ensure reliable printing, it is important that this distance is equal over the whole build surface. This is done in a mechanical way by physically adjusting (tilting) the bed.

  • Optimal bed to nozzle distance for first layer.

    The first 3D printed layer is the foundation of your print object, it is crucial to get this layer right. When the distance is too close, the filament cannot exit the nozzle and could get blocked. When too far away the extruded filament will not adhere to the print surface and causes your print to fail.

  • The height difference between the two hot-ends.

    For a dual head system, it is important that both nozzles extrude filament at the same height, otherwise this could cause problems when printing.

Next Generation automatic build plate leveling

To enable automatic calibration, we engineered an innovative mechanical build plate leveling feature and probing mechanism which physically touches the plate. To level the build plate, the printer will probe the plate at 4 positions to determine the slope angle of the plate. After this it will turn two cogs underneath the plate to put the build plate in the correct slope angle.

Why mechanical auto leveling?

The easiest comparison would be a camera with hardware or software stabilization of the lens. Software stabilization is the low-cost solution, hardware stabilization is a more complex system but gives a better end-result.

Our automatic calibration system saves time:

  • When you are a beginning 3D printer user.

    This enables you to start printing with the shortest learning curve possible. It automatically sets you up for a successful print, without the need of any fiddle with your machine.

  • When you need to swap your build plate often.

    The automatic calibration saves you time when frequent build plate swapping occurs. Swapping build plates often is beneficial for small series production settings or when you use different plates for different print materials.

  • After swapping hot-ends.

    After exchanging a hot-end it is required to recalibrate your machine, because the new hot-end will most likely be different in dimensions. Even though the difference can be very small, it is still required to calibrate.

  • To ensure reliability of first layer printing.

    To get optimal build plate adhesion of the first printed layer, it is essential that the plate is clean from debris, leveled and finally the distance between the hot-end tip and the plate is equal over the whole surface.

A true innovation in bed probing systems for 3D printing

To properly perform the leveling feature, a reliable and accurate probing system is necessary. The probe mechanism directly measures at the hot-end tip.

Measuring this way has several benefits compared to other probe systems.

  • Save time, by not needing to externally calibrate the probe mechanism with respect to the hot-ends.

  • Eliminates to manually compensate for production tolerances in hot-end lengths. This is useful when often swapping out hot-ends.

Silent Operation at just 34 dBA

At only 34 dBA during printing, the Pro 2 is the ideal companion in the office environment, classroom or living room. A quiet eyecatcher which allows you to work without any distractions. It's the most silent desktop 3D printer available today.

How did we do achieve this?

Based on the Arduino DUE platform a new control board was designed. It boasts a 32bit ARM processor at high clock speeds. This makes it able to use stepper drivers which can do 128th micro stepping allowing extremely low noise operation of the stepper motors.

The control board operates at 24V, which improves the efficiency of the heaters and steppers compared to previous generations which work at 12V.

Filament flow detection - No failed prints

The filament flow detection monitors if the expected flow of filament enters the hot-end. If this is not the case the print job will be paused, so the user can correct the error and continue printing.

Imagine printing km's of filament and a small glitch occurs. This however, could ruin your precious print-job. The filament flow detection prevents this type of failure.

We have saved already large amounts of filament and hours of precious time with this feature.

Direct drive extruder – optimal control

The Pro 2 features direct drive extrusion for 1.75mm filaments.

By extruding very close to the hot-end opening, you have the best possible control and enables you to print flexible materials. Normally flexible filament is very prone to buckling when you push it through a hot-end.
