SmartBOB controllers and dedicated accessories / Re: What do I need to be able to probe Z.with 411 and g540

 Well Steve I changed the switches by wiring them all to ground and now they all seem to be talking to the 424. The over travel switches work fine but they axes won't Home when I push the button.  Mach4 see the switches so I will try changing the config.

I apoligize for my ignorance on this stuff Steve but I wired J16 and J17 to ground but no go. So I looked at the switches and they have 0V opposite the wires going to the 424. Will I screw up the board if I put 0V where the ground is designated? Or should I get a 12V source for J16 and J17 12V pin. Bill

Well Steve, I believe I have it all connected. They will light up on the Machine Diagnostics page when I change them to Active High and go back out on Active Low. Alas the switches do nothing to the program when I push on them. I feel that I am missing a step on the setting up.

Sorry Steve, I kind of butted in to this thread. I have the 424 and 407 boards. I have homing switches and ++ and -- switches. It looks like there are 8 Inputs on J16 and J17 but some are already assigned as I am using your PMDX-424-Sample as as a base for my profile. Can these do double duty if so assigned in the Inputs Configuration? Also do I need to wire the +12V and Neg on J16 and J17?    Thanks, Bill

Ok. Got the polarity direction thing sorted out. Next project is Homing. I can turn their lights on by turning off the Active Low switch but my machanical switches don't seem to be communicating with the board. Sorry to bug you with such simple crap. I'll see if I can work this one out without smoking the board.   Bill

Well, at least I did know that Z+ is up and my jog buttons are correctly oriented. Where should I look to tell the the Z that the touch pad is Z-?

Sorry Steve, I am pushing the lower right icon on the Touch popup box. I was expecting Z to come down and touch my puck to set Z for this work piece but it went up (minus) instead. Sounds like something really simple that I should know already.  Thank you, Bill

Steve, What am I doing wrong that makes my Z go + instead of - while finding the material top?  Thanks, Bill

Thanks Steve, I'm good to go now. Everything is working and I'm happy. Thanks for leading me through it.  Bill

'm confused as usual. I read this:
The setup is simple, but we really should add this to the PMDX-407 information.

The Com on J2 of the PMDX-407 should connect to the Common of your VFD
interface. If you have the VFD working now, you have already done this.

The Run on J2 of the PMDX-407 should connect to the relay Com on J18 of
the PMDX-424 (or the Com terminal of any SmartBOB with a relay of any
external relay that you may add).

Connect the relay N/C on J18 of the PMDX-424 to the FWD input on your VFD.

Connect the relay N/O on J19 of the PMDX-424 to the REV input on your VFD.

Must be for a different setup other than I need for a simple 3 axis mill.
Thanks for resimplifing things for me. This stuff is all new to me,  Bill

in another post that "The PMDX-407 uses an analog control voltage and simulated switch contacts
to control the VFD, so it interfaces in a very different manner." I didn't read anything in the 407 supplemental about anything analog. all that I have connected on the 407 is a wire to J18 common and to the VFD common. I didn't think the Analog instructions applied so I'll give this a try.

I hear the little click when I tell it to spin or stop but nothing happens. I fear it might be that the Delta Series E VFD needs something done to it since I went from Chinese to the 424 and 407. I looked the manual up on line but really don't know anything about VFDs. I get "Error spindle speed set to zero" in Mach4 but I think I have Mach4 set correctly. Thanks, Bill
