Hello Guys,
I have problems with Mach3 and Probing with my Pokeys 57E

When I run the Code/Script in Mach3 via debugger step by step, everything works super fine.
But when I run the buttonscript normal, one of the axis, or all together fail.
By failing I mean, that the axis behaves like it got probing contact way before touching the workpiece.
mach 3 probe error - overrun: limit (1378410135 -1613) 7 and so on...

My setup:
Probing Pin = Pin19 (1k Ohm pullup resistor)
Probing Pin is positiv and is connected to my workpiece (1m copper wire).
The Endmill has contact to ground throught the hole machine.
The plugin shows perfectly that if I touch the workpiece the LED in the IO-Monitor goes off.

Mach3 version: R3.043.066
Pokeys: newest Firmaware

Script for XYZ Left corner:
Sub Main()
SetOEMDRO(800, 0.0000)
SetOEMDRO(801, 0.0000)
SetOEMDRO(802, 0.0000)
Sleep 500
code "G0 Z15 F200"
code "G0 X10"
code "G0 Y10"
code "G0 Z0 F150"

If IsSuchSignal (22) Then
code "G31 Z-15 F50"
While IsMoving()
Wend
SetOEMDRO(802, 0.0000)
Sleep 500
code "G0 Z15 F200"
code "G0 X-8"
code "G0 Z-4 F100"
End If

If IsSuchSignal (22) Then
code "G31 X10 F50"
While IsMoving()
Wend
SetOEMDRO(802, -3)
Sleep 500
code "G0 X-10 F200"
code "G0 Y-8"
code "G0 X10"
End If

If IsSuchSignal (22) Then
code "G31 Y10 F50"
While IsMoving()
Wend
SetOEMDRO(802, -3)
Sleep 500
code "G0 Y-10 F200"
code "G0 Z10"
code "G0 X0"
code "G0 Y0"
End If
End Sub                                     


Can someone help me?
Is it the Input-pin or is it the plugin or Pokeys, or mach3?
Its totaly random which axis fails...sometimes all...very rare, all axis work.
The error Code is:
mach 3 probe error - overrun: limit (1378410135 -1613) 7 and so on...

Thanks for yout time and help.

Cheers Lukas

... my Pin 19 is connected to a pull-up resistor (1k) to 3,3V...
same like recommended in the manual for pin 48 and 49 (step output y and z 470 ohm pull-up)

In some posts i read that you have to put pull-up resistors to +5V???
Are the Inputs 5V tolerant or 3,3V?
The manual says "We advise adding an additional 1 kΩ pull-up resistor on pins with an external switch"

The pic in "External pull-up resistor wiring for pins 48 and 49" shows 3,3V

okay, i tried it with +5V - No difference

Did you ever solve this. I am running to the same error Probe error - overrun: limit using the probeit wizard.

Hello, my name is Mark, I am hoping someone can give me some advice on Touch probe digitising. I need to digitise gun stocks using 4th axis between centres. I would like to digitise the surface and outline in Mach3 and import into Alibre to do mods, toolpath and recut stock from blank. Is Mach3 capable of doing this with it's built in wizard, or do I use other software, what probe do I need to get and any other general advice of value. From Australia, we hope you are all hanging in during this turbulent time and wish our American friends well. Thanks in advance, Mark.

Mach3 can do it but it will need some gcode or a macro to do the actual scan.

The problem you may have is that any holes slots or through holes would need to be filled or covered by thick tape to stop the probe diving down the crashing into the stock.

Depending on the shape its not always possible to get the whole of the profile due to undercut faces so some times it has to be scanned left to right then rotate and then right to left then rotate or rotate and take 360 points then move left or right then rotate.

Each time a point is taken it is stored.  It can take a long time and create a huge point cloud.  Optical scanning may be a better option.

Thanks for the prompt response Graham. I seem to remember years ago I was able to use a Mach3 wizard to get the point cloud data you are talking about, just not sure if it still works. I can drop macros in for the Z depth and 4 sided rotation. I have used a creality scanner but would like to automate the process as I have more CNC's than I use continuously so time is not an issue, thanks for the advice re hole blanking and undercut issues. I am now 60 and built my first machines with Mach3 controllers when I was 30, then stopped, so I feel I may be a bit on the outer with what can and can't be done today. I like Mach3 but wonder if other control software like UCCNC might be better suited for digital touch probe scanning. A bit lost I guess.
Thanks again for your help, it is very much appreciated.
Regards
Mark
