Got the container turned round, decided to position it differently from my original intentions. That brought a problem as it meant the fan would be going out the side which is now hard up against my GRP cabin or out the end which is right against a wall. So had to haul the plasma out, birl it round and get it back in. It was a bit of a task but with a few 50mm dia pipes and a crowbar and jack I managed it.
Spent the last two weekends getting three phase run in and the container wired. Bit of a pain as there is no way to fix anything other than drill holes through the container or weld bars for tying the cables to but have it all done now and never blew anything up
Made up a limit switch similar to Daves for touching off the surface, not sure if I need to raise it a bit as it is quite a bit lower than the torch when extended but if I do then it is just a matter of boring and tapping 3x M5 holes.
Pics below of cylinder and guide rod, was going to buy a double rod cylinder but when I saw the price I decided to use a single rod one I had and make it into a guided one
Dave,
how do you do the touch off? Is it in the M3 macro or do you have seperate moves for the offset move, the G31 then the move back?
