This guide will teach you how to obtain a sharp focusing point with the Laser Head PRO.
Note: The Laser head pro comes pre-calibrated. A factory value is printed on a sticker on the plastic bag.
If you just received a laser head PRO you can quickly set the correct calibration distance by entering this value in the Z Focusing Distance Field under Head Proprieties (Select the “gear icon” under Laser Head PRO under Maintenance>head).
No further steps are required in this case.
Safety First: PUT ON THE PROVIDED SAFETY GOGGLES
For the purpose of engraving and limiting health hazards the laser beam on the laser head PRO has been focused at a fixed range, close to the lower tip of the Laser Head PRO.
Therefore, being the focusing point now fixed, the distance of the Laser Head from the object to engrave or cut must be changed to match the focusing distance.The laser head pro can automatically go to the focusing point after the correct distance is found and saved on the system.
As a rule of thumb, the focusing point can be found 4 to 8 mm below the tip of the laser head PRO.this distance may vary depending on hardware revisions and assembly.
First of all, let’s download the calibration sample Gcode at http://download.fabtotum.com/gcodes/Laser_pro_calibration.gcode and upload it on your FABUI using the Object Manager as usual.
