Master Guide: The Logbook for Laser Cutting and CNC

If you work in a digital manufacturing workshop, you know the story perfectly well: you do ten different tests on a scrap of new acrylic, find the exact perfect combination of speed and power in LightBurn, and quickly jot it down on a piece of masking tape or a post-it note stuck to the machine's chassis... The next day, when the big order of 500 pieces arrives, the piece of paper has disappeared into the MDF dust and you have to waste time (and material) guessing the parameters again.

Or worse, you end up sending yourself messages on WhatsApp full of random numbers and strange measurements that, in two weeks, you no longer remember which client or project they belonged to. LazSpot Digital Notes is designed to eradicate the chaos in your workshop, centralizing your technical knowledge in the cloud.

The Myth of the "Universal Parameter" in Laser Cutting

One of the most common beginner mistakes is searching internet forums: "What are the parameters to cut 3mm MDF on an 80W laser?". The harsh reality is that universal parameters do not exist. What works on a user's machine in Spain will burn the material of a user in Mexico. Why?

  • Tube Degradation: A CO2 laser tube gradually loses power. 60% power on your new machine on day 1 will be equivalent to 75% power in month 10.
  • Material Density: MDF is not pure wood, it is a glued particleboard. Different suppliers use different resin densities. MDF from store A will cut like butter, while store B's will require two passes.
  • Humidity and Climate: Wood absorbs moisture from the environment. Cutting wood in the rainy season requires more power or slower speed than in the dry season.

Because of this, it is vital that you keep a digital record of YOUR own parameters. With LazSpot, you can create a note titled "3mm MDF Parameters - Local Supplier" and update it as your laser tube ages.

What should you document in your Digital Notepad?

For a parameter note to be truly useful in the future, just writing down two numbers is not enough. Get used to saving templates with this technical information structure:

1. Cutting and Engraving Data

  • Speed (mm/s or mm/min)
  • Maximum and Minimum Power (%)
  • Number of Passes
  • Line Interval (DPI) for engravings
  • Air Assist (High/Low/PSI)

2. The Kerf Enigma

The "Kerf" is the width of the material that the laser beam vaporizes when cutting. If you design a box with press-fit joints without compensating for the Kerf, the box will be loose and fall apart.

Note down in LazSpot the exact Kerf value for each material thickness. For example: 3mm Acrylic Kerf = 0.15mm.

3. Maintenance Logbook

Create a note dedicated to the health of your machine. Record the dates when you:

  • Changed the distilled water in the Chiller.
  • Cleaned the mirrors and focal lens with isopropyl alcohol.
  • Installed a new laser tube (to track its lifespan in hours).
  • Lubricated the linear rails.

4. Client Measurements and Specifications

If a client calls to request a custom box for a wine bottle, note the diameter, height, and the text to engrave in a new note. Use the "Share Easily" feature to generate a link and email it to them so they can approve the specs before you cut the material.

Formula to calculate and document your Kerf

To calculate the exact kerf you should note in your digital notepad, draw a 100mm wide rectangle in LightBurn. Cut it with your laser. Measure the resulting piece with a digital caliper. The mathematical formula to obtain the Kerf is:

$$Kerf = \frac{\text{Dimensión Esperada} - \text{Dimensión Real Obtenida}}{2}$$

If you expected 100mm and the piece measures 99.7mm, the difference is 0.3mm. Divided by 2 (because the laser cuts on both sides of the vector), your Kerf is 0.15mm. Note this golden number in LazSpot immediately!

Privacy and Professional Organization

Unlike chats or public forums, your notes in LazSpot are completely private and encrypted under your user account. Our interface is designed to minimize friction: you open the web page, write your parameter or idea, save it, and return to your CAD/CAM software in a matter of seconds, without the distraction of social media notifications.
