60W Chinese Laser Engraver Modification
John Stevenson:
I have one of the larger Ikea plastic storage containers with a lid, under the bench / stand that it sits on, like your with anti freeze as it backs onto a door that isn't used.
Handy as I can vent the exhaust through the door with a laser cut plastic grille over it.
Don't know if this applies to yours but somewhere in the menu's, File, I think there is an options tab so you can fine tune but it needs a vendors password.
RD8888 seems to work on most machines.

That's quite a unit. I know nothing about them but find it interesting.
As far as anti freeze goes if you need something non poisonous you could use Propolene glycol. I use it in my hot water solar system. The inspectors are very much concerned about people using regular automotive type of anti freeze in their solar systems (for good reason) and demand proof of what is being used. It's good for really cold weather - we get winters where the temp. goes well below -20 C and there have been no problems. I've heard that propolene glycol is used in ice cream but am not sure if that is just rumour.
John.
awemawson:
Certainly propylene glycol is safe, and used as you say as a food additive, but as I have 300 litres of diluted ethylene glycol (and another 25 undiluted) I used what I have as it is a sealed system.
When I set up the furnace I had intended to use propylene glycol but the cost was prohibitive in the quantities I needed.

I'm getting to rather like this laser cutter :ddb:
Today I needed to fit a 'cigarette lighter socket' in the JCB 803 mini digger - why as I don't smoke :scratch: Well I need to sport an amber flashing beacon when I'm stream clearing on a public footpath that borders our land. Only place on console was a 'switch blanking cover' but totally wrong shape.
Needed to make up a little 50 mm x 35 mm plastic panel with a 'keyhole' for the socket. Quickly draw it up in Autocad, download it as a .DXF to the PC I've dedicated to the laser cutter, open it in RDworksV8 (which is the graphics package that came with the machine, squirt it to the laser cutter and bob's your uncle.
Literally quicker to do than type this description. Previously I'd have been drilling and filing and cursing when it didn't fit. This went in first time
