this is driving me crazy. renamed the pics and tried to send again, but the screen just turns white. However, I made a mistake in my last post -- i have 5vdc going to each power input area, one from a wall wart type battery charger and one using the PC via a usb cable. one end of the the limit switch wires is inserted into a hole labeled 5v in the input bar and the other end is inserted into the hole right next to it, labeled 15, which i take to mean pin #15. is that correct?

don't know why but the pics won't send, although when i tried to send them the second time, i got a message saying that i had already sent that file. I do have the limit switches wired in series and have put 5 vdc through them to the POWER part of the board that has 3 little screws, with the red wire in the 5vdc hole and the black wire in the ground hole.

OK, I have done that. Maybe I should mention that I have to bob hooked up and i can run the 3 axes through it -- but i wanted to use the limit switches as kill switches, that is, i figured that since i have 6 limit switches at various locations around the machine, if something went wrong i could just manually trip a limit switch to stop the machine. But when I run the machine and trip one of the switches, nothing happens. i am now wondering if i haven't set up the pins/ports correctly.

Hi Hood,
The markings are the same unless noted in the email I sent to Arturo. Did you get that?

Hood -- I see you're online; I'm trying to attach a wiring diagram but am having trouble. Hang in there. My last email wasn't posted but an attachment was, so it might be confusing. I thought if I could post the wiring diagram and the email I sent to the guy who provided the BOB you might be able to help me with it. I'll try again. Thanks, Bob

School goes on.....I have a home built all-leadscrew 3-axis 24" x 48" cnc router w/ Xylotex steppers and I just bought an optical breakout board through which I want to run limit switches. I have wired all the switches together using the NC (normally closed) pin, put 5 VDC through the switches, and hooked it to opening #15 on the board. I then went to the ports and pins input section and activated the x, y, and z plus and minuses, and entered pin #15 for all of them. When I turn everything on and trip a limit switch, nothing happens and none of the LEDs light up on the diagnostics page. Anyone know what I'm doing wrong?
Also, when I use VCarvePro to calculate a toolpath, it asks me what version of Mach 3 I want to use for the postprocessor, and it has 4 choices (Mach 3 Arcs, Mach 3 Line, etc.) How do I know which version I have?
Thanx again, Bob

Well, if you ever decide to learn, give Fraser a try -- his Flashman series is the funniest stuff I've ever read.
Thanks again, Bob
