5-11 Adjusting the Focus Distance

Description:

If you have an unacceptable engraving or cutting result, the distance between the surface of the material and the nozzle tip must be checked. (The correct distance is 12mm.)

There are a few ways to make sure the distance is correctly set. Please follow the instructions below.

Method 1 - Using the Focus Probe:

• Place your material on the honeycomb and push the probe downward to be as straight as possible. 
  
  
  
• Turn the knob clockwise to raise the bed up until the material slightly touches the probe, and the correct distance will be set.
  
  
  
  
• If the probe is broken, you can find the file in Beam Studio, or the file here can also be downloaded.  Using 3mm acrylic for cutting this probe is recommended. 
  
  

Method 2 - Using Coins:

The coins will be easy to get and used to measure the distance.

• USD  >> US quarters (25¢) x 7 pcs
• EUR  >> 50 cents x 5 pcs
• TWD >> $10 coins x 6 pcs
• ...etc. (You can search or measure the thickness of the coins you have)

Method 3 - Using Materials:

If you have materials with thicknesses of 3mm, 4mm, 6mm, etc., you can use a number of them to get the 12mm focus distances.
