What we have been doing at Little House

You can read about previous activity at What we did last year


2020-1-1 Wednesday

  • Jon and Andy came in to do some tinkering with the laser cutter
    • modify a plastic crate so we could soak the honeycomb bed of the cutter in Zep.
    • removed the honeycomb bed of the cutter to soak
    • broke the 'quick release fitting that attaches the hose to the tap
    • made a shopping list of what else we needed in screwfix
    • realised that it was a Bank Holiday and screwfix was probably closed :(
    • texted IanB in the hope he might have one - he did - and he brought it round for us (along with a donated PC).
    • repeatedly pressure washed the honeycomb - not perfect, but much better.
    • cleaned, washed and vacuumed all the insides of the laser cutter case.
    • spent some time making measurements of the laser power using our'dohicky'.
    • spent some time aligning the laser tube to see if power could be improved - there is probably room for some improvement still, we seem to lose a lot of power at each 'bounce' in the optical path.
    • have concluded that a spare lens and some spare mirrors are worth having.
    • need to investigate cleaning techniques for the mirrors and lens.
