Malcolm here, from a cafe by the beach in Kalymnos.
Seems like you are making much better progress than I expected. I thought you would all be down at The Boilerhouse, carpentering, painting, hacking RFID entry systems, etc…
Anyway, from what you have posted, I need to add:
The water chiller is in the boot of my car in Maidenhead. For regular (Hackspace) use the water chiller will need to be fitted. I was planning on bringing it over shortly after my return - towards the end of September.
This post from the rLab thread is very relevant:
Hi I’m Jon from RML, and I’m mostly responsible for the dismantling of the x axis tensioner at Richmond, but also buying the spare belt and ‘gearwheel’ that you should have received with the cutter. We concluded that the original aluminium belt tensioner was wobbling and that this was caused by the failure of the brass axle due to wear, and the failure of the bearings within/between. I think it needs a new axle turning, and then new 9mm bearings should fit into the new gearwheel (IIRC that’s what I spec’ed it to be drilled for). I was using the laser for engraving scale brickwork on buildings for a model railway layout, and the wobbly x axis was causing problems with alignment across the work piece (brick courses didn’t line up).
We were just about to get a new axle turned from steel when the power supply failed, and failed, and failed… and then a member bought a new cutter instead…
So the x-axis idler needs further attention, as may the running line of the x-axis belt.
I suggest that you invite Ryan from rLab to show you how to focus the laser beam. If he can’t do it, and he is happy that Alex has the necessary knowhow, then ask Alex.
The same is true of use of the control panel and other manual control of the laser.
Your neighbours at The Boilerhouse might object to smells as well as noise. Filters from hydroponics have been suggested as a possible solution for smells.
