General Mach Discussion / Accuracy in Ref All Home

« on: January 08, 2013, 02:21:14 AM »

Hello,

I have practiced repeatedly some tests with AutoZero macros.

He concluded that:
Ref All home, in relation to the probe gage block,
presents a random error up 0.0150" / 0.381mm (+/-)

This happens when I turn off the step motor
and Ref All Home, before running the macro AutoZero.

My question is:

With limit switch and Ref. all Home,
How I can get maximum accuracy in Z axis?

1. - Some settings?
2. - Some macro / script especially for Ref all home?

I want to know, as you do that?  What is presetter?

Anyway, I'm trying to make a macro,
because I do not find the script Auto ToolZero for Table detect surface and Detect different height offset bits and update Tooltable.

best regards.

I thank you for your information, that has been enlightening for me.

Then I decided definer Machine coords the Z zero fully up. And so it was already.

Also connect an aluminum plate of 1/2" as a probe,
I saw the diagnostic screen, digitize the signal lights when I connect, and off when disconnected.

I have only one problem to solve:

I have not got the script for Auto ToolZero for:

1.- Table detect surface to configure workoffset Z=0  (to set table top as zero).
2.- Detect different height offset bits and update Tooltable.

I have no idea how to do this that I'm missing.
I think then able to use my machine.

I appreciate your time and attention.

General Mach Discussion / Define location of zero in Z axis, in milling.

Hello,

I'm a newbie and I just made all the limit switch work to perfectly,
thanks to the valuable support received in this forum (thanks Hood).

My machine is milling type, three axes, MDF table below, router above.

I purchased the system Craftman QuickRout (Router Bit Connector/Adaptor Kit),
and like update the compensation tooltable for bits of varying heights.

I do not want to destroy my bits.
I do not want to damage my machine.
I do not want my bits drilled base table.

I think about security,
and let me know your experience,
Where it is recommended to define the machine location of the zero z axis?
Limit up or limit down?

So also would like to know why up or down.
I have intention to cut materials of various heights.
My prejudice tells me zero down is better, I not sure.

I appreciate any related information.

Thats what I thought it would be, just tell Mach that it is a normal condition by clicking on it and you should not see that again.
Hood

Your help has been extremely useful.

I appreciate and thank you for your time and attention you gave me.

Sincerely.

The Debounce Interval simply adds a delay into Mach when it sees a signal. If you have electrical noise being picked up by your switch wiring then Mach can think it is a limit switch being triggered. The best approach is to use shielded wire and ground one end of the shield to a star point ground.

Regarding the Abnormal Condition, click on it and see what it says, if it is just something about axis not referenced to normal just ok it to clear and set that as normal.
Hood

Thank you again.

-List of Abnormalities-
Axis are not Refed to Normal Condition...

Sounds like you either have bouncing switches or noise being picked up by your cables. Set a debounce Interval of 2000 in General Config and see if that helps. If it does then you really should sort the problem, ie make sure your cables are shielded and properly grounded or replace with switches that have a positive snap action.
Hood

Thanks a lot.

Still do not understand what is debounce Interval,
I need to read and I'll read PDF support.

I setting debounce Interval of 2000
and the index debounce like was = 0

Finally the three axes working properly.
I am very happy and grateful to you for your help.

I can only other detail,
When beginning Ref all home,
buttons ZeroX, ZeroY, ZeroZ, Zero4 every turn red,

then the engines do their job until limit switch,
Then one by one the buttons change to green, excellent.

Zero 4 is only red (that does not bother me).

When finished
The problem is that is yellow "AbNormal Condition".


I think I should not disable motor 4 ("A-axis"), that is slave axis Y.
I do not know if I need any change setting
Or if I need to make a change to the code script:

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
'DoButton( 25 )  ' I try remark but not fine.

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)
 
I appreciate any related information.

I appreciate your time and attention.

Hello people,

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 hurrah, 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 hurrah, 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.
