Laser Subcommittee Meeting 2020-06-20
Attendees: BlakeS, NickB, Felix
Possible rearrangement of machines for combined ducting and chiller stacking
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
LG500 Little Red (out-of-order)
Requires air extraction
Test location near rear rollerdoor?
LC1290 Big Red
Z-stepper current, set by DIP switches on the driver: raised to 4.3A, was peak-current 3.5A, (max is 7.8A)
Occasional stiction at 3.5A: acquire grease?
Level check bed: front RHS corner is up 2mm
Vent holes: any feedback?
Empty compressor tanks, water trap
