Hello,

I'm a newbie, using the demo version R3.043.066
I'm wiring a CNC machine limit switches.
The machine is three-axis.
The X axis with one motor
The Y axis with two motors (A slave)
The Z axis with one motor

The input signals:
X++, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
X--, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Xhome, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Y++, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Y--, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Yhome, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Z++, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Z--, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Zhome, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
A++, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0
A--, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0
Ahome, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0

In the diagnostic screen: I see the Input Signals current state all work fine.

Then when I click the "Ref all home" button.

...Press Reset... Emergency Mode Active...
Limit Switch Triggered


After that.

I proceeded to disable the Z++ and Z--
...and hurra, the "Ref all home" continued with the Y axis.

Then the Y axis work very well with the three signals
"Y++", "Y--" and "Y home". All signals enabled.

...and the "Ref all home" continued with the X axis.

Then the message again:

...Press Reset... Emergency Mode Active...
Limit Switch Triggered


I proceeded to disable the X++ and X--
...and hurra, the "Ref all home" continued until completion.

In the home/soft limits: I check enabled the Auto Zero in all axis.

Then the questions:

1.- Why not run the X and Z axis auto zero returning?
(M3Home and M1Home is on in diagnostics screen)

Note:
The Y axis work fine with the three signal Y++, Y-- and Yhome
and not active the Emergency Mode y run the autozero returning.

The only thing I find different is that the "Y" axis has slave "A".

2.- For safety on my machine. Like the Y axis.
I want to activate the signals Z++, Z--, X++, X--.

without triggering Emergency mode active, like the Y axis.

How to configure this?


I have thought that it is a software error Mach3

I can fix with wiring, but sought a solution with Mach3



Any case appreciate any related information.

I appreciate your time and attention.

From the diagnostics screen you can reference each axis individually.
Do you have the homing setup correctly? It's all in the Mach3 manual.

Slowdown the reference approach speeds and get each axis working one at a time.
I believe you may have some signal levels not quite up to scratch or a faulty ground.

I have seen many a machine not using referencing because the setup is out of wack.

I've seen the diagnostic screen.

I have verified the performance of each signal separately.

Clearly I have Mach3 should work with the X, Z just as "Y". That's what not occur.


Some postings on internet says that I should install double switch.
One for home and one for limit.
As I am a rookie, I could have accepted.
But I tested and found the aberrant functioning of axis Y, which works very well with one switch and three signals and + + and -, yhome.

Detects home,
engine returns, with auto zero,
and emergency stop limit machine.

again
Ref all home work very well with axis Y.

How to make axes x, z axis work as Y.?

The script is:
DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

Try this. Get the home switches working first.
Are the home and limit switches in same position?


The input signals:
X++, DISABLED, port 1, Pin 10, Actived low X, Emulated, HotKey 0
X--, DISABLED, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Xhome, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Y++, DISABLED, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Y--, DISABLED, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Yhome, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Z++, DISABLED, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Z--, DISABLED, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Zhome, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
A++, DISABLED, port 1, Pin 13, Actived low X, Emulated, HotKey 0
A--, DISABLED, port 1, Pin 13, Actived low X, Emulated, HotKey 0
Ahome, DISABLED, port 1, Pin 13, Actived low X, Emulated, HotKey 0

If you use home for limit it can only be a + or -. not both.

If you use home for limit it can only be a + or -. not both.

I believe that this is incorrect, and you can use a single switch for all three.

I'm guessing the original issue is possibly noise triggering the switches?
