¶ Control Card Replacement
This guide provides a step-by-step walkthrough for control card replacement in laser machines. It covers safety precautions, required tools, enclosure removal, control board disassembly, proper cable handling, and reinstallation to ensure stable operation and prevent wiring errors.
¶ Note:
Before unplugging the cable, please take a photo to record the connection status to prevent incorrect wiring during reinstallation.
Keep the removed screws in a safe place to prevent loss.
¶ Tools Required
Hex wrenches (M2 & M3), Phillips screwdriver
¶ 1. Removing the Machine Enclosure
① Ensure that the device power is disconnected.
② Use the M2 hex wrench to remove the screws on the rear cover, then take off the cover.
③ Remove the screws on the right-side panel.
④ Before removing the right-side panel, disconnect the following cables:
- Emergency stop switch power cable
