Machine Setup and Job Configuration

Slide Overview¶

This slide walks through the complete machine setup process from cold start through job execution. Each step has a specific purpose for safety and quality — skipping steps risks equipment damage, poor results, or safety incidents. Students will internalize this as a checklist they follow every time they operate the laser.

Instruction Notes¶

Startup Sequence (in order)¶

Step 1: Water Chiller (FIRST) Turn on the chiller and verify water temperature reads 18-22°C. Wait for the water to circulate (30-60 seconds). The laser tube MUST NOT fire without active water cooling — even a few seconds of dry firing can crack the tube ($200-800 replacement).

Step 2: Exhaust System Turn on the exhaust fan and verify airflow (hold a tissue near the intake — it should flutter visibly). If using a filtered system, check filter saturation indicators. The exhaust must be running before any material is cut.

Step 3: Air Assist Turn on the compressor or air pump. Verify air flows from the nozzle by placing your hand below the laser head. Air assist prevents flame-up and clears debris from the cutting zone.

Step 4: Power On the Laser Turn on the laser cutter's main power switch. The control panel should initialize and display the home screen. The gantry may home automatically (move to origin position).

Step 5: Load the File Transfer the design file via USB, network, or SD card. Import it into the laser software on the control panel or connected computer.

Step 6: Configure Layer Settings For each color layer in the design, set: - Mode: Cut, Engrave, or Score - Power: Percentage (referenced from the material settings database) - Speed: mm/s - Processing order: Typically engrave first, then score, then cut (innermost cuts before outermost)

Material Placement and Focus¶

Step 7: Position Material Place the material on the honeycomb bed. Use hold-down magnets or weights if the material is not perfectly flat. Ensure the material extends beyond the full design area (check with framing).

Step 8: Set Focus Adjust the distance between the focusing lens and the material surface: - Place the focus gauge between the nozzle tip and the material surface - Lower (or raise) the bed/head until the gauge sits snugly - Remove the gauge carefully - Focus error of more than ±1mm will significantly affect cut quality

Step 9: Set Origin Move the laser head to the desired starting position. Set this as the job origin in the software. Verify the origin mode matches the design (top-left, center, etc.).

Pre-Cut Verification¶

Step 10: Run Framing Execute the framing/boundary function. The laser head traces the outer rectangle of the design using only the aiming laser. Verify: - The entire design fits within the material - No clamps, weights, or bed edges will be hit - The design is positioned where intended - Nothing obstructs the beam path or gantry movement

Step 11: Start the Job Once all checks pass, start the job. Remain present and monitoring throughout.

Key Talking Points¶

The startup sequence is a safety ritual — water first, exhaust second, laser last. Reversing this sequence risks tube damage and fume exposure.
Always run framing before cutting — 10 seconds of verification prevents wasting material and machine time
Focus is the most commonly forgotten step and the easiest way to ruin a job — make it part of your physical checklist

Learning Objectives (Concept Check)¶

[ ] Students can execute the complete startup sequence in the correct order
[ ] Students can configure layer settings for a multi-operation job (cut + engrave)
[ ] Students can set focus, origin, and run a framing check before starting a job
