Check direct at the port.

On the socket, comparing to pin25 as ground i have the following signals with mach running and reset ok but no outputs.....

1=High
2=High
3=Low
4=Low
5=Low
6=High
7=Low
8=High
9=Low
10=High
11=High
12=Low
13=High
14=High
15=High
16=High
17=Low

Make any sense?

Thanks for helping BTW.

You would need to operate an output to see whether it is working or not, so for pin 9 MDI M3 and the state should change, M5 and it should revert to original state.

Small update, if i shut down mach 3 then go into device manager and disable/re-enable the LPT port, the relay energises as all output pins 1-9 were reading high.

As soon as i load mach3 and press reset, the relay drops out and cannot be re-energised.

At least the port, lead and relay are proven working.

But what goes on when mach does a reset?

If i reboot the PC, when it comes back up, the spindle relay energises, as soon as mach3 is loaded, it drops out and I cannot get it to re-energise again.

Seems mach3 is not doing something right??

Just tried a fresh install on another PC, different make but exactly the same behaviour.

Change the active state of the output.
If that doesnt work attach your xml and I will take a look.

If by that you mean active high/low then yes I have tried.

The machine is at work so I will have to upload the file tomorrow.

FIXED!

There was a little post i found on a google search.

There is a tick box - "Max CL Mode Enabled", this was checked, unchecking solved the issue


Happy days, thanks for the help.

Yes that would do it
Max modes are for specific machines and they preset the I/O to dedicated pins which you can not change, even by setting pin numbers in Ports and Pins.
