  4. Mount the Taper laser mount to the laser with the taper towards the bottom as shown

    • Mount the Taper laser mount to the laser with the taper towards the bottom as shown

    • Fix it with the four M3x12 cap screws

    Edit

  5. Mount the laser bracket to the spindle as shown Make sure the bracket hooks onto the spindle bracket at the bottom

    • Mount the laser bracket to the spindle as shown

    • Make sure the bracket hooks onto the spindle bracket at the bottom

    • Clamp the bracket with the M4x12 cap screw and lock nut

  6. Remove the M3 screw and washer from the stand-off next to the X-motor Mount the cable holder with the M3x12 cap screw as shown The cable holder is used to secure the laser cable when the laser is removed from the machine

    • Remove the M3 screw and washer from the stand-off next to the X-motor

    • Mount the cable holder with the M3x12 cap screw as shown

    • The cable holder is used to secure the laser cable when the laser is removed from the machine

    • Slide the transfer board into the cable holder

    • Connect the tree point laser cable to the input and the four point cable to the output of the transfer board and make sure the cables are in the right order.

What happens to the black wire from the mosfet switch cable, there is 3 cables on the mosfet side and just 2 on the cnc shield side where does the third go?

Impossible to slide the laser transfer board into the 3d printed holder without damaging the pcb. Now just dangling outside. Please revise this error.
