Laser Subcommittee Meeting 2020-09-19

  • Attendees: BlakeS, NickB, BenC, AdamM
  • Beau: Possible rearrangement of machines for combined ducting and chiller stacking
    • measure ducting, plan for rotating: LC1290 -90degrees; KH7090 90degrees
    • extra exhaust duct for LG500 would need 8m of ~100mm diameter tube
  • We'd still like red dot beam combiners, which would render getting a tube that has a built in aiming beam moot
  • KH7050 Kellogg/Middle
    • Focused by Blake
  • LG500 Little Red (out-of-order)
    • Requires air extraction
    • Test location near rear rollerdoor?
  • LC1290 Big Red
    • BenC: Move rear right limit switch, new mounting shim holes 10mm/15mm
    • BenC, AdamM: Fix XY squareness
      • cut 400 x 397.5 mm “parallelogram”
      • line up gantry at midway Y point
      • undo coupling screws in axle under laser tube, wind Y to resquare (using dial gauge) and fasten coupling screws
      • cut 600 x 595.5 mm “square”, 708mm both diagonals
    • relevel: gap was 11/11/12/18 (!)mm in back right corner
      • detension&adjust righthand Z belt
    • Empty compressor tanks, water trap
