Shop night 3/17 2025
News / updates:
- Chiaki and Lizzie are joining us as tool testers!
- Form3 has been recovered from torn tank / print film
- Formlabs donated a printing tank and replacement of a liter of clear resin (v4, compatible with v4.1); also a resin pump, usable with 5 liter resin containers.
- MSDS library has been updated with all materials used for SLA printing, as well as laser-cutting MSDS sheets for acrylic and plywood
- Siberian has been moved to DF shop - and will be brought on line in April.
Repairs / major adjustments pending:
Replace linear bearings in the 2 ‘black’ frame Prusa mk3 printers - bearing sets are on back table.
Check / correct mirror alignments on all BlackCats - 3 mirrors per unit.
There is now a fixture for centering the Y axis mirror … design and 3d print done, the Bombay laser has been aligned along the entire path
every mirror / line was out by at least 4 mm, the down mirror was out 5 mm, which is pretty bad, considering that distance is only 6"
Also, on Bombay, observed the tubing from the air pump was pinched off under the chiller unit - so it’s not been getting flushing air - probably happened as we were doing other maintenance on the laser. We may want to replace the tubing that’s in use with something a little stiffer.
Debug / fix Prusa #5 filament sensor.
Maintenance work pending:
P1P overdue for Z axis lead screws clean & lube
Creality Ender 3 needs hot end cleanup and re-assembly
Cleanup old resin left behind from SLA printer(s)
As we come into higher humidity months, store all filament in dry 5G pails
