Back from Texas, the folks a CandCNC are really nice, it was a pleasure meeting them. I have the table partially finished now, I have my home switches installed and a z axis limit switch to keep it from damaging the head again, and they work! z axis hits a limit, it stops the machine, click reset and override limit and you can manually back it off the limit, if you click go home, the gantry goes - to home switch x and y then backs up +.500, i will tune that in closer as this table does not have a full 8 ft of cutting travel for y axis, ok it does, but the torch head has to be past the slats to get that length
anyhow I'm pretty happy about this! I have some ways to go yet in setup and have run into another couple issues trying to cut a file, but I think it is for another post
I just wanted to say thank you to everyone as every bit of information posted here and private messages has helped me in more ways than you can imagine!
