ports and pins
« on: December 18, 2008, 10:05:56 PM »
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

It may be the case that your BOB requires the Input pin to be grounded through the switches, what make is it?. As for the PP afraid I cant help other than saying there are not different versions of Mach such as Mach Arc etc, I would imagine a quick email to Vectric would give the answer on which is most suited.

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

If the pdf is not the same as your BOB then is there any markings on yours?

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

OK I think you are needing 2 power supplies, one from the PC and the other should be seperate to preserve the opto isolation. The PC one goes to the 5V and 0V at the top of the pic and your other power supply goes to the 5V and 0V at the bottom of the pic. You need to keep the jumper wire in to enable the board.
