Convert from CNC head to handheld mode¶
Think of conversion as a checklist with a sign-off. The most dangerous error is a mismatch between the head physically installed and the mode/configuration the controller is prepared to fire.
Prepare¶
- Finish or cancel the CNC job and park the axes in the documented safe position.
- Disable laser output in software and at the source/key controls.
- Isolate the energies required by the supplied procedure. Apply workplace lockout/tagout where servicing exposes hazardous energy.
- Verify the source is disabled and observe the specified wait time before disconnecting source/head interfaces.
- Clean the work surface and stop dust-producing work nearby.
- Lay out labeled caps, the handheld head, cables, gas connection, ground/work clamp, and—if welding—the wire feeder.
Remove the CNC-head configuration¶
Support components before loosening them. Disconnect only the interfaces identified in the Gweike sequence; never pull on a cable or fiber. Cap every exposed optical interface immediately. Store the CNC head in a clean protected holder so the nozzle, ceramic, protective window, and connectors cannot be struck.
Maintain broad bends in the armored source fiber. Do not make the cable fit by tightening a loop or routing it through a door/pinch point.
Install the handheld configuration¶
- Inspect caps/connectors and accessible protective optics without touching their surfaces.
- Mate the optical interface using the exact keyed procedure; stop for dirt, damage, resistance, or a misaligned thread.
- Connect the control/trigger, safety, ground/work-clamp, and gas interfaces to their documented ports.
- Route the hose/cable bundle so it cannot snag, form a trip loop, touch hot metal, or enter another machine.
- Fit the correct clean nozzle/tip and consumables for welding, cutting, or cleaning.
- Select the matching handheld mode and head configuration in mLaser/control software; load a preserved verified baseline.
Safety-function check before output¶
With the source output disabled, verify trigger return, safety/contact logic, emergency stop, door/access controls used by the handheld setup, gas control, wire-feed control where fitted, and software state. Any control that sticks, disconnects intermittently, or permits an unexpected ready state is a stop condition.
Restore CNC mode later¶
Use the same isolation and cleanliness standard in reverse. Do not assume parameters restored automatically. Confirm CNC head, gas, FTC connection/calibration, source selection, and the original saved axis/process configuration before a no-emission frame and test coupon.
