Just set up a new machine Mach 3.0, we are testing the setup using one switch at the moment (eventually all 3). When we ref all home the machine moves correctly but the software is not recognizing the switch when it is triggered. ??

Do you see the LED light on the Diagnostics page when you press it?

No We do not see it...and we set Mach up on another computer to rule out possible port problems..but got the same results. We have traced all our wires back to our cards and everything is 100%, we have come to the conclusion it is software related. Port is set for ecp/epp...
We have spent 3 days now and no luck......

can you attach your xml please

Hi there, just figured out the advanced options to send email.....

If you remove the parallel cable from your breakout and short pin 11 on the cable to a ground pin on the cable do you get the LED lighting in Mach?

We have tried that and YES the Mach software does indicate with the yellow Flashing display LED...We are using an accu opto breakout board and spoke with them on the wiring and confirmed that we are wired up correctly...
Our procdure is:
We are using the Ref Y button on the diagnostics screen in mach to send the (Y) axis towards the home switch... Is this the correct procedure and way to set it ???

Well if the LED lights in Mach when you short the pins there is nothing wrong from cable to Mach so it has to be from breakout board to switch.
Yes Ref Y if you have the switch to pin 12 as in your xml.

So heres the break down...
We are testing (Y) and move to the limit switch which now lights up on the mach screen..
We then press Ref (y) to zero our position off the switch.
Next we manually move the (Y) away from the switch about a foot or so.
Then we tell mach to go back to our Ref position....by selecting ref all it shows the count back to our position
but the (y) axis is not moving back at all.
If i goto MDI and type in G0 Y0 mach then works correctly.....
So what am i missing ????

Hi, Maxy
With "Ref. All", Z ref's home first then Y then X, Is this what your getting ?

This is a 3 axis machine and we are only testing the Y axis switch....so how does mach or where does it save or get it's Ref data from ?..
As like i said...we ref off of the limit switch by pressing (Y) button to Zero the Y position. Then when we move away
from the switch , we should just press REF (Y) and it should return to it's positon of Home that we originally selected as our reference.
it seems that mach does not know where to find our home position we selected, however on the mach screen it indicates that it has
moved *********.xx position when in fact it has not physically moved at all.
So it's like geting it's data from where ???? we have tried selecting the DRO auto to be on and this made no difference.

Are you troubleshooting this problem by yourself? Or do you have a flunkie working with you?
Ask the flunkie if he plugged all the lines in.
I think that maybe the Z...Y...X... ref all may work. Set up all 3 axis as if ready to go even though you only have y actually set up with home switch........what you think?
-
If all you can test with is Y, go in ports and pins, inputs and disabel your x and z home switches. Click on machine cord. then ref.all home. if it homes and zeros your y axis Machine dro, click machine dro again to display your work coord. (MACHINE COORD WILL BE RED AROUND THE EDGES WHEN THE DROS ARE SHOWING MACHINE COORD.) Now if you click on zero Y button beside Y DRO, your machine and work coord. should both be 0.
