Collision protection

• Raytools BM110/BM111 "Collision Protection" Kit

• BM111 have a specific internal magnetic sensor and a sacrificial ceramic assembly, but Raytools also offers an external 3D collision mount for high-end machines.

• Raytools TRA Nozzle Assembly

• Raytools 3d head sensor

• Sacrificial Ceramic Rings If a full magnetic mount is too bulky for your Z-axis design, you should rely on the ceramic ring. For 1.5kW, this is the standard point of failure. Original Raytools Ceramic Rings (AliExpress)

LinuxCNC stack

• QtPlasmaC
• Mesa 7i96S (or 7i76E)
• THCAD-10 height sensing

Controller box

• Raycus RFL-C1500 User Guide
• Maxphotonics MFSC 1000W-1500W Manual: If cloudraw source uses the Maxphotonics "G3" architecture, this manual provides the specific 8-bit power bus logic (Pins 1-8).

Laser side signal condition on DB-25

• Modulation (Pin 19): Use an RS-422 Differential Receiver to maintain a crisp 20kHz pulse and block EMI over the long cable run.
• Power Supply: Tap Pin 17 (+5V) on the laser's DB25 to power your buffer circuit (verify voltage with a multimeter first).
• Grounding: Use Pin 25 (GND) as your logic common; ensure the cable shield is grounded at the laser end only.
• Safety Isolation: Use Optoisolators for low-speed logic (Enable, Ready, Error) to protect the Mesa board from high-voltage faults.
• Hardware: House the circuit in a shielded aluminum box mounted directly to the laser using a DB25 Male-to-Male gender changer.
• Cable Quality: Deploy a double-shielded industrial DB25 cable (foil + braid) to act as a barrier against servo motor noise.

DIN rail systems

• 24V Field Power system, Mean Well SDR-120-24
• General purpose relay 38.52.7.024.0050 and socket 93.02.7.024
• Narrow Slot Wire Duct
• Push-In Terminal Blocks
• Grounding Terminal Blocks

Height sensing:

• Preamplifier (BCL-AMP), Converts capacitance to 0-10V for the THCAD.
• Ceramic Ring, Isolates the nozzle to act as a sensor.
• Shielded Coax Cable, Connects nozzle to Preamplifier.
• Isolated 24V PSU, Eliminates signal noise from the 1.5kW source.
