OK,

Think I have it(famous last words!) Where is "autolimit overide" general config? I would have done otherwise but there reall is not any other places to mount switches so I guess I will have too set up the offsets.

Brett,

Can't seem to get the network connection to work right now for the XLS and my usb drive gave up the ghost a while back, however here is a bad picture of where the switches are mounted. The X & Y switches are mounted off the rectangular motor mounts and contact the stationary bed of the machine (aluminum casting that the arrow is pointing left at the x home area) the Z axis switch is up top and contacts a accuator mounted on the spindle slide. Think I already figured out the crash factor, set the Y -- limit and ran into the switch and had to power down to manualy back off the switch.

No Problem Dave,

By the way I always wondered what happened to PacMan after Ms. PacMan left him for a Missle commander, looks like he's just gulping up the juice.

After several false starts, waiting on parts etc. I finally got the limit switches mounted on my Taig mill, N.C., wired in series, figured out the basic settings so the quill goes to the top, table full left and full out. Now the question is how do I set the offsets to reflect where "program" coordinates really are? I am thinking I need to enter something like -9.5X and -4.5Y to tell Mach where I want my start point to be. Same goes for soft limits, I'd like to set up so the machine can't back the table all the way out of the leadscrew nut also.

Now that the switches are there another question comes to mind, if I am right up on the switch and jog into it what happens? Do I crush the switch or does Mach prevent that? Once the switch is opened can I back away or will it be a PIA? I can post my config file if needed.

Dave,

It's a SCR switch so you would need to connect a AC load in series with the "output" terminals. You could use a light bulb or small AC motor to test but you will not be able to measure with your ohm meter to see if it's switching.

PS- it's normaly open so when there is no 3-32VDC on the input the output terminals are not conducting any current, when you apply the input, the SCR will conduct current and turn on your load (motor, pump, lamp etc.)

Bill,

Yes I did run it and it seemed to work fine, I have since given up on LC though, just too flaky and difficult to use interface. Matter of fact I got a refund and threw away the key! I don't have any pictures of the mill but it is a standard issue Taig mill that I changed the leadscrews out for the upgraded CNC set & motor mounts. Right now I am still trying to get the home/limit switches mounted and all the wires tucked up, it's covered in swarf and doesn't look like much.

Now to search out a program that works without going broke or loosing my mind trying to get it to work!
