Exhaust fumes extraction problem

Options:

  • Remove window above hallway door, replace with wood. mount pipe onto wood.
  • Cut hole in door, fit pipe over hole in door
  • Cut hole in air duct, mount pipe over hole
  • Decide on coarse filter, as the supplied filter will clog if use without.
  • Open door and toss out hose when in use. Revert when done.

Electrical problems

  • Hook up ground The machine's ground is wired internally to the euro socket, so no need for external ground.
    • Unless there is no ground on the socket so when connecting the ground must be checked.

10/4 Laser cutter does not give output power anymore after first successful test run. no high frequent buzzing anymore one should expect. Only what appears the sounds of sparks on first fire. then nothing.

16/4 Opened up laser power supply (I know what I am doing) (famous last words) and it appears the flyback transformer is toast. the secondary of the transformer measures fully open. (or the resistance is >30 M Ohm)

Also the power supply appears to be a 80 W model whereas we have a 90W tube. Thoughts ?

2 options.

  • get new power supply. about €200 ish
  • get new flyback transformers and just hope it works. This is the cheaper option.

Power rating is 90W. Tube length is 120 cm.
