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
- Would we like one?
- Nick, Blake: yes; Fletcher: no
- Fletcher: Recommends crowdfunding it at https://finance.artifactory.org.au/
- TODO
- 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
- Hour meter
- The hour meter started from 1.6 hours, at 20171210 , 512 beam-active cutting hours per annum
