Icaro Laser Software Manual Fixed -

Since “ICARO” sometimes refers to LightBurn (customized for certain controllers) or a generic laser GRBL software, this guide focuses on the fixed, practical steps – assuming you want to get your laser working reliably without crashes or misalignment.

3.7 Laser Power Calibration – Corrected Values

Erratum corrected: Table 3.2 in the original printing contained swapped values for 532 nm vs. 1064 nm. The corrected table is below.

| Setpoint (mJ) | Actual 532 nm (mJ) | Actual 1064 nm (mJ) | |---------------|--------------------|---------------------| | 50 | 49.8 ± 1.0 | 50.2 ± 1.0 | | 100 | 99.5 ± 1.5 | 100.5 ± 1.5 | | 200 | 198.0 ± 2.0 | 201.0 ± 2.0 |

To perform calibration (fixed step order):

Place the energy probe 25 cm from the output aperture (not 10 cm as previously stated).
Fire 10 conditioning pulses at 10 Hz (not 20 Hz – high repetition rate before calibration will damage the Q-switch).
Then begin the automated calibration routine via Tools → Calibrate Laser.

1. Introduction

Icaro is a laser display software designed for creating and live controlling laser shows. To ensure your software runs "fixed" (stable and reliable), follow this setup guide from installation to projection. icaro laser software manual fixed

Section: Connecting to the Laser Machine

Incorrect previous version (example):

“Press the connect button, then maybe select COM port if needed. Ensure machine is turn on.”

Fixed version:

1. Connection Procedure

Ensure the Icaro Laser machine is powered on.
Connect the USB or Ethernet cable between your PC and the laser controller.
Open Icaro Laser Software.
Go to Machine → Connection Settings.
Select connection type: USB / Ethernet / Wi-Fi (if supported).
For USB: choose the correct COM port (visible in Windows Device Manager under “Ports (COM & LPT)”).
Click Connect. The status indicator in the bottom‑right should turn green.

2. Troubleshooting
| Issue | Solution | |-------|----------| | No COM port appears | Reinstall USB drivers from the Icaro driver folder. | | Connection lost during job | Check cable and restart both software and machine. |

Step B: Projector Settings (The "Fix" for Warped Images)

This is the most critical step for a "fixed" output.

Scan Rate: Match this to your galvo scanners (e.g., 30k, 40k, or 60k). Setting this too high will overheat your scanners; too low will result in flickering.
Correction (Geometry):
- Project a test pattern (usually a square or grid).
- Use the Keystone/Geometry sliders to straighten the image.
- Ensure the square is perfectly square on the wall/surface, not a trapezoid.
Safety: Ensure the "Safety Shutter" or "Interlock"

The Distribution

What followed was a six-month saga known as "The Monday Drops." Every Monday, OpticDistress would upload a single, high-resolution scan of the "Fixed Manual."

These weren't just pages of text; they were artifacts. The pages were filled with handwritten notes in the margins. A diagram of the laser tube cooling system had a handwritten arrow pointing to the flow sensor saying: “This is a lie. The sensor is fake. Jump pins 4 and 7 or the machine will error out in 10 minutes.” Place the energy probe 25 cm from the

Another page, regarding the "Fixed" software configuration, contained a hidden key combination (Ctrl+Shift+F4) that opened a "Service Mode." The original manual never mentioned this. The Fixed Manual revealed that Service Mode allowed users to calibrate the stepping motors to a precision of 0.01mm, transforming a cheap hobby machine into a professional tool.

4. Laser Firing Fix – No Faint or Overburn

PWM signal fix
- If laser stays on or too weak:
  - $30=1000 (max S value)
  - $31=0 (min S value)
  - $32=1 (laser mode – PWM)
- In software: set S-value min 0, max 1000 (or 255 depending on controller).
Test fire
- Manual mode: Send M3 S100 (S100 = 10% power if max=1000).
- Use a piece of thermal paper or wood to check.
