Filter box not drawing smoke from the laser. Machine down.

Anemometer readings:

  • Front intake vents, lid closed = 0, 178 no filter
  • Center honeycomb, top = 3.3. virtually no fan movement
  • Center vent under bed = 985 – I think the baseline read was not over the vent, I got a 0 when I just held it under the bed)
  • Intake at filter = 1790
  • Outflow at filter = 957 (after repositioning accordion filter was able to get it to 1650)
  • intake for shop based exhaust = 1037

there are significant variances especially in the outflow at the filter

Conclusion… The filter box filter was very clogged. Supposedly re-usable. Need washing instructions.

Actions taken: Put the laser on old-fashioned ventilation, cleaned optics.

Working on setting up the big filter box.

Filter box output connected. Support needs to be moved. Needs to be replaced with proper vent run sooner rather than later.

Anemometer readings:

  • Front intake vents, lid closed = 372
  • Center honeycomb, top = 213
  • Center vent under bed = 349 (measurement really hard to take, maybe need to make a stand off)
  • Intake at filter = Still need to get
  • Outflow at filter = 1579 (very very blowie)
  • intake for shop based exhaust = 1357 (very very vacuumy)

12/31/19 – Crafty

Marco came and swapped out the smaller filter box with a large 220v filter box. Replaced HV power supply as the spontaneous firing was indicative of a busted diode in the HVPS. Lubricated rails.

    Hi! I took the Laser Basics and Certification class two Saturdays ago, but have not taken the post-class exam yet. Where is the link to that?
