The LED turns on when tripped and off when not tripped.

I'm almost positive that I loaded the .dat file in the mach3 program, at least I don't get any messages saying that I'm running a  Demo.

No outside controller, direct serial port.

This Is the G31

N0090 M06 T1  (Plasma, 0.0592 in kerf)
N0100 G00 X8.5889 Y2.0867 Z1.5000
N0110 G31 Z -100 F19.685
N0120 G92 Z0.0
N0130 G00 Z0.0000
N0140 G92 Z0.0
N0150 G00 X8.5889 Y2.0867 Z0.0000
N0160 M03

This is the G28.1

Go to the help button at the top and selct about. It should give you the license info (your name) or say DEMO. 

From teh MDI line do the probing call.

G31 Z-2 F5

While it is running trip the switch. Does it stop ???

(;-) TP

Looked under the help/ and my name was there so its not in demo.

Used the G31 Z-2 F5 code and the Z just zeroed and never drives down to touch off.

The probe led didn't light up to tell it that it touched off.

If I trigger the switch the probe led lights up.

HUM there is NOTHING in that code that tells the Machine to zero itself.

You have things going on that I have never heard of before with Mach3 (;-)

hi there I need help bad!!! I'm using a geckog540 with a proma compact thc , with sheetcam with a floating head and micro switch attached. now a few things I need to know are

- mach3, how to set it up with homing I have
        - Z home and the pins set up right it does get the signal in diagnostics screen
        ? in homing/limits do I need to change anything such as ( soft max, soft min, or activate home negative?)

in the code it uses G28.1, when I run the code the torch goes down but if stops when the Z DRO hits 0 I thought it would keep going down into the negative until it finds the material and activates the Z home switch on the floating head, so just to test I tricked the DR0 to think it was 30mm off zero when it was actually touching the material but as it goes down and activates the Z homing switch nothing happens and it drives hard into the job?

I am using a full version of MACH3 with Plasma screen set , sheetcam with PM1000-THC post processor and now I'm stuck ass hell
any help would be great I'm at the end of my rope and will end up throwing the machine in the river.

Is the z switch that is activated setup as the PROBE input or the HOME input, i think it must be the Probe to work as limits and homes are disabled when doing a G28.1

Maybe be better to start a new thread too, the one this in is over a year old?

yeah mate I'm new to this forum and I bit useless. I have tried using PROBE input still no good and I have seen a few posts that say the MP1000 post processor uses G28.1 and that I must use the Z axis home, also I did see 1 post that said to use Z++ limit as the switch so I gave that a go and it just triggered the Z limit and went into emergency E STOP
 another problem I am having is the THC , I get the signal in diagnostics screen in test mode  torch up,down ect but the Z axis DRO doesn't move and I have a full copy of mach3. so I set the same pins to activate the z-- and z++ jog at the bottom of the pins page ,and than it moves but jogging doesn't really work well for THC I think

The code seems to work fine if I set the z axis up at a good height so that it wont sink into the job it goes down until the dro says ZERO and it has triggered the home switch but that trigger didn't affect the Z DRO but as it comes up and the trigger is released I does set the Z DRO to zero than goes about its work until it lifts and goes to the next cut and the Z axis will only go down to  Zero which at this point is the height of the material than goes through its thing again but ends up higher up off the job , now at this point its not triggering the switch at all as it is above the job and the floating head doesn't touch the work and with every new cut it gets higher every time .
seems to be resetting zero every time without even using the  Z Home switch ? I don't know I'm a boiler maker building the bed and sorting out all the hard ware was a breeze now I feel like a 5 year old lol. my guess is its something small and basic as I am very green with it all

Concentrate on one thing at a time, disregard the THC.

As far as I know ALL the top-of-material sensing routines use the PROBE input only - get this set up and make sure that the floating head switch shows up in diagnostics as a PROBE input on the screen. Do that first, it's vital.

Once that is working, go to the MDI line and type

G28.1 Z5.000

The head should start moving DOWNWARDS and stop when the floating head switch triggers, it might be worth triggering it early by hand for the first time, this will give you time to e-stop if it fails.

Try that ;)
