Essential Systems

Auxiliary Gas Control System

• Importance: Laser cutting requires auxiliary gases such as oxygen, air, and nitrogen. An auxiliary gas control system enhances the usability of your DIY equipment.
• Details: We have created a detailed DIY Auxiliary Gas Control System Checklist (as shown below) and offer a package purchase option for all materials in the list. You can download the checklist PDF from our website.

Z-Axis Slide Table

• Importance: The cutting head of a laser cutting machine requires height adjustment through a following system. A smooth slide table is necessary to connect our cutting head to your Z-axis, ensuring smooth cutting operations.
• Details: We offer a slide table selection that meets DIY equipment standards. Purchase this slide table and pair it with a 400W motor and drive system to achieve perfect control of the cutting head on your DIY equipment.

Auxiliary Systems

Air Compressor

Here is the information regarding the air compressor for DIY fiber laser cutter (1500W-6000W) project:

1. Exhaust Volume: The exhaust volume should be 1.3 cubic meters per minute (1.3 Nm³/min).
2. Outlet Pressure: The outlet pressure should be fixed at 1.55 MPa.
3. Air Pipe Specifications:
   • Inner Diameter: 8mm
   • Outer Diameter: 10mm
   • Pressure Rating: The air pipe should withstand a pressure of no less than 2.0 MPa.
4. Gas Cleanliness Requirements: Ensure the gas is clean, free of oil, and free of water.

Alternative Gas Options

If you choose not to use an air compressor, you can use bottled nitrogen or oxygen for cutting. Here are the settings for each gas:

1. Nitrogen (N2): The pressure should be set between 1.2 MPa and 2.0 MPa.
2. Oxygen (O2): The pressure should be set at 0.8 MPa because the SMC proportional valve we provide has a pressure limit of 0.8 MPa.

Voltage Stabilizer

A voltage stabilizer is an essential component in any DIY fiber laser cutting machine project. Its primary function is to maintain a consistent and stable voltage supply to the equipment. This stability is crucial for several reasons:

1. Protecting the Laser Source: The laser source is the most expensive and sensitive component of a laser cutting machine. Fluctuations in voltage can cause significant damage, reducing its lifespan and efficiency. A voltage stabilizer ensures that the laser receives a steady voltage, preventing these potential issues.

2. Enhancing Performance: Stable voltage levels contribute to the overall performance and precision of the laser cutting machine. Inconsistent power can lead to variations in cutting quality, resulting in uneven or incomplete cuts.

3. Extending Equipment Lifespan: All electronic components within the laser cutting machine benefit from a stable voltage supply. This reduces wear and tear, leading to a longer operational life and less frequent need for repairs or replacements.

4. Ensuring Safety: Voltage fluctuations can sometimes cause dangerous situations, such as overheating or short circuits. A voltage stabilizer mitigates these risks, ensuring safer operation of your DIY laser cutting machine.

Laser Consumables Package (Annual Consumption)

We’ve put together a recommended list of consumables for a year’s worth of use with laser cutting heads (2000W-6000W). This list includes protection lenses, nozzles, ceramic bodies, sensing cables, lens cleaning materials, laser protection goggles, collimation lenses, focus lenses, and rubber seal O-rings. We want to make it easy and convenient for DIY fiber laser cutter hobbyists to keep their machines running smoothly. You can download the comprehensive Annual Consumables List to have everything you need in one place.

Additional Materials

Beyond the recommended materials, you can purchase other items in the checklist according to your specific needs. We are always ready to provide valuable assistance.

How to Determine if Your System Can Be Upgraded

Before embarking on a DIY upgrade project, it’s crucial to assess whether your existing system is compatible with new components. Here are the key factors to consider:

1. System Compatibility: Identify if your current system supports bus communication or pulse communication. This will determine the type of cutting head and control system required.
2. Motor Type: Determine if your motors are servo or stepper. For bus systems, use bus-compatible cutting heads, while pulse systems should use pulse-compatible heads.
3. Power Requirements: Ensure that your power supply can handle the upgraded components, especially if you are increasing laser power or adding more advanced features.

Recommended System: XC3000S

We recommend the XC3000S for most DIY upgrades. It supports both bus and pulse communication, making it versatile for different setups.

Choosing the Right Cutting Head

• Bus vs. Pulse: Select a cutting head based on your system’s communication type.
• Model: Choose based on your equipment’s power and intended use, such as 3D cutting.
• Collimation-Focusing Ratio: This depends on the material being cut and the power of your laser. For example:
  • 3000W: F100-125 or F100-150 ratios
  • 6000W: F100-150 or F100-200 ratios

Cutting Head Consumables

• Protective Lenses: Match the lenses with your cutting head model.
• Copper Nozzles: Standard based on the cutting head model and power, with customization options for specific processing needs.
• Ceramic Bodies: Chosen based on the cutting head model, standard quantities provided.
