General Mach Discussion / Re: Plasma torch settings via spindle....

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

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??

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?

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.

Pin 1 goes high with reset enabled and low when reset is red.

Pin 9 does nothing regardless of spindle setting.

Will look for another cable, this one came with the BOB.

Thanks, that's what i have but no joy.

M3 makes the Output1 flash in diagnostics but i'm getting no relay activity on the BOB, the manual states Pin9 is spindle control and i have mach set to port 1 pin 9 for O/p 1

Any other tips??

As expected, I'm not getting any torch control signal on the BOB relay.

The diagnostic screen shows no change on the pin grid when flicking the spindle motor signal on/off so it looks like mach 3 is not outputting any spindle/torch command.

Can someone run through exactly which settings to set so i get a spindle/torch "on" signal on pin 9 output please???


Thanks

Great, that's where I have it now, should be able to start testing today hopefully

Its a bit vague, but is it permitted to power up a BOB without the motor drivers connected?

I want to test the E-stop, torch control and limits before wiring the motor drives and motors.

Could someone let me know which settings need to be set in mach to enable me to control my plasma torch via the spindle relay on my BOB?

I'm generating g-code in sheet-cam but am not at the stage where I can test anything yet as I'm still building the table.


Thanks
