Title: Setting Zero Fixture Z to zero using an external button
Post by: DanieGouws on August 06, 2021, 09:43:43 AM

Hi,

On my Denford CNC lathe, running a Pokeys57 card and Mach4 I'm trying to zero the Zero Fixture Z using an external button. I have done that very successfully for Cycle Start, Spindle Start and Spindle Stop by mapping external buttons to inputs and then editing the Mach4 Screen using "Edit Screen". Then I loaded the "Screen Load Script" and adding:

[mc.ISIG.INPUT0]=function (state)
        if (state ==1) then
               CycleStart()
        end
end,

I assume I need to replace the CycleStart() with a variable the refers to the "Zero Fixture Z"; for the "Zero Fixture Z" key, under properties/events I found the variable "Zero Z" but that gives me a compiler error....

Hope you can help,

Kind regards and thank you
Danie

Try this;

mc.mcAxisSetPos(inst, 2, 0.0)

Hi,

It works perfectly! Thank you very much. Is there an easy way to determine the correct "parameter/ structure" for other buttons?

Regards

Danie

In your Mach4 folder there is a file called Mach4CoreAPI.chm
That has most of them
