Title: Another tool zeroing...but unique...
Post by: JacobHarding1978 on October 13, 2019, 06:31:57 AM

 :-\ :-\

Ok guys...I am hoping someone else has had this issue crop up.

For quite some time I have set my tool length and height by the tried and tested paper method.

But as with all things progress must happen for profit.

But now I cry......

What's happening is that when I setup my auto tool zero device I wire it as directed.  One lead to 5vpc....one lead to pin 11....and one bridging the 5vpcgrnd to the ground for limits and e stop.

Now when the unit is activated and the digitize diagnostic icon/light turns on when the touch plate touches the tool ok....I manually lift it to the tool tip...I will explain why in a sec....so I safely assume my wiring at this stage is correct.

Buuuuuuuut.....I have no motor axis movement at all.....I cannot jog, mid or have a program move the equipment.

If I remove the wiring and disable the probe I have full control of my axis movement.

I have this breakout board and using this instructable to make the touch plate.

If anyone has had this issue before....please educate me....

The probing input HAS to be an independant input. It cannot be combined with limits or homes.

Just a thought (;-) TP

Yeah....I thought as much, but the probe ground has to share the grounding pin.

But if that was the case it would just trip an e stop error when contact was made to close the circuit.

Anyhow.....back to the paper method.

Your probe should be connected as per attached image.

Thank you....I tried this approach to no positive end...it seemed as there was no power going to the circuit through the probe...

I think you need to apply the 12V to 24V power to your breakout board for the inputs to work ?

Done that....have 12-24 for power and running 5v for signal conditioning....

Check you have your Probe Input (Mach3 Ports & Pins) Enabled, set to Port#1, Pin11, Active Low.

Yep.....used tool auto setter.....that's the entries it made.....

So with your probe connected as ZASto has suggested you are still not able to make any motor axis movement ?

Yes sir...no movement....I can make a video if anyone wants so they can see what's happening.
