23-12-2010 #152Are switching live and neutral, or just live?
im using a cheap 16A switch to switch both live and neutral... are you saying i should be useing a relay and only switching the live ? ill comence experimentations when its not so dark
iv bought a plug in rcd adapter so hopefully it will win the race against the main one and save my house mates missing flash gordon on the telly :)

ok i removed the surge protector, ran the neutral passed the power switch and bought a rcd adapter
no joy :(
tripped the building out a couple more times (house mates cursing and growling)
stripped the whole thing down looking for a short
i managed to norrow the problem down to some kind of interaction betwean my 24v supply and the driver board
took them over to my girlfreinds house, tripped her power out a dosen times before i twigged than one of the brass risers i was using to mount my driver board to the power supply was reaching through the supply case and touching the top of one of the large caps in there
FFF***nvpkdjsdkcning Hell!!!!!!
thats what i get for being lazy and not making sure they were clear... three days with my thumb up my arse!
ill have to keep my fingers crossed that i havnt damaged the board

its a bit scruffy at the mo but it is working well :)
iv been looking at ways of clamping work to the bed without drilling and taping hundreds of blind holes that will inevatably clog with shit
im thinking i will drill and tap some choice holes as and when things develop
i may have a job with a hundred or so small control panles to engrave so iv been looking at ways to clamp easily and with repeatability
20mm o/d o-ring with 0.34mm protruding above face
one way valve
one way valve holding the vacuum,, at 20mm O/D it only just holds onto this alli plate
35mm o/d o-ring 0.3mm protruding above the face
valve holding the vacuum
takes quite a bit of effort to get this one to pull off
i left it stuck there like that for an hour and i had to give it a good pull to get it off, i wouldnt trust it to hold while on the cnc but it gives a good indication of how well the valve holds the vacuum
very simple and cheap to make in any size , im looking at machining both sides and just placing them between my bed and work peice out of the way of the cut
once iv proven the cocept i may use a peristatic pump (nice and quiet) to pull the vacuum
iv also orderd some transparent valves so i can see which modules are failing to seal
cant see it not working at least for engraving :)Last edited by blackburn mark; 09-01-2011 at 12:45 PM.

Mark
Another tip is double sided tape for your application.
