    Using Z Sensor The inductive sensor will allow you to automatically palpate 4 calibration points to correct mounting imperfections. This only detects metals (detection ~ 1mm for non-ferrous metals (aluminum, ...) and ~ 3mm for ferrous metals (steel, cast iron, ...). Caution: use of a glass plate is prohibited with the use of the bed of aluminum.

    Step 2 : Balancing Z motors To reduce the correction of the auto-leveling, it is highly advisable to balance the height difference between the two Z motors.

  • Page 21: Z-Axis Calibration

    / 21 Step 4 : Z-Axis calibrating What is the target ? To properly calculate the correction of the auto-leveling we need to determine the difference of our printhead with the heating bed when palpated with our sensor. Note: This difference is therefore a negative value beacause it will lower the heating head of measurement recorded up to get the point Z = 0.
  • Page 22 5 - Type the «G92 Z0» command to set the point Z = 0 of your printer 6 - Using the arrows, move your Z axis 30mm upward, so you will be at Z = 30 7 - Type the «G30» command to perform a probe and detect your metal bed 8 - Here is a typical example of a response in your logs: Note: For this example, we just measure a difference of 0.49mm from our printhead 9 - To set the value of the specified gap type the following command :...

    / 27 ANNEX Printing of a piece with Repetier Host We will first choose a 3D model to print. We suggest you to start with a simple object like the «Y Motor», with a fairly large plate surface to be able to observe the printing of the first layer (decisive) as comfortable as possible. IYou can also go to the Thingiverse website and find a simple object to print (cube or another simple objet without difficulty).
