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/

KH7050 Kellogg/Middle
Focused by Blake
LG500 Little Red (out-of-order)

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
