[lewi444]

Hello I was needing some help hear is the problem I was cutting the end off a 4x8 sheet metal jogged it across the end but i forgot to turn the thc off it got to the edge when it went off the edge torch went all way down hard stop blu the main fuse. Now after new fuse & checking all outher fuses I start a program goes to start goes down to 0 out but never does just keeps on going down till blows fuse or you stop it. I pulled the wires off the circit board when I opened the control box I was fairly shur I got them back to the right connections. the wires do have continuity when you trip the switch on the flowting head. It's a Dyna cnc 4x8 table thay are not in buisnes any more I shur could use some help on this one.bumed out Keith!

in the dro do you manually jog it to the top of the steel and zero it ? The only thing I can think of it it dose'nt know where it is.


OR the limit is'nt working try to toggle the z limit and see if it toggles on the screen. I also have a dyna table.
