Thanks for clarifying that. I got a SSR as I thought solid state generally means more reliable. It's not a huge issue if the spindle doesn't turn off I don't think since I'll have a normal switch nearby on the mains in addition to the relay. It's a 25 amp relay.

Are switching live and neutral, or just live?
interesting
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 :)
Re: Fingers crossed it'll cut ally
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 :)
Attachment 3570
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
Attachment 3573
20mm o/d o-ring with 0.34mm protruding above face
Attachment 3571
one way valve
Attachment 3572
one way valve holding the vacuum,, at 20mm O/D it only just holds onto this alli plate
Attachment 3574
35mm o/d o-ring 0.3mm protruding above the face
Attachment 3575
valve holding the vacuum
Attachment 3576
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 :)

hi phil
sounds messy and not quite as elegent for 100+ pices ... iv used bu-tac before now for engraving :) worked ok
