A small update.
Tinkered a fair bit yesterday with the laser.
Had to go through the water cooling system and flush huge amounts of antifreeze out of there.
Also moved the cooler to the cabinet under the laser, so all the tubing is now also internal. This goes for the air compressor too. It saves on space, makes the unit easy to move, but also makes it harder to remember to check water level, contamination, temperature.
Did some patching and rewiring and got it firing. Did a full calibration and it seems fine. Not checked how much power it can give tho.
There is a lot of stutter on the rails, especially going faster than 80mm/s, but hoping lubing (grease) can suffice. Otherwise the bearings are shot…
I did not get around to sorting the air exhaust. The air evacuation of the laser is real important. The more flow the better for many reasons. There are a bunch of ventilation bits on site, I brought in some more. Its a bit of a puzzle/project I am happy to solve but even happier to let someone else take, partly or fully. i do think we need a bigger fan, and most probably a bigger outlet. The one fitted in the container in 100mm on the inside, and even smaller on the outside.
So, to sum up:
It works, its calibrated, it semi-clean.
It needs some love and lubing, and probably would do well with some tubes, bearings and such swapped. Exhaust ventilation needs to be sorted. I wont be able to promise any work on it before the weekend.
Also; must say the container solution is not only perfectly suited for the laser and the other neat bits of tech, but super nice to be working in. So happy for the new home for an old trusted workhorse!
