... 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

PoKeys / Pokey57E Probing error
« on: August 20, 2021, 04:54:40 AM »
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

does it matter that I'm running the demo mode of mach3?

Has anyone had this issue and could advise some tricks?

Does Pokeys Plugin or Pokeys itself support backlash settings in Mach3?

Is anyone able to set steps per mm with let's say 4 digits?
If Yes, what mach version are you using?

hmm, they told me:
"Unfortunately, this looks to be Mach3 issue."

Hi guys,

I'm using a pokeys 57E with newest firmware
and Mach3 Version  R3.043.066

calibrating my machine...
setting steps per mm and backlash...

actually my x y and z axis should go by 640 steps /mm

I started with the X axis and did 100 times the same stuff... homing the machine, moving it towarts the dial indicator via G0 x52 (for example)
(the dial indicator axis is quite parallel to the X axis)
write down digits move another 5mm write down digits and go back to the first position to get the backlash...

when moving the 5 mm the x axis seems to moves average 0,002 mm to much...so i tried to set new steps per mm.

MY PROBLEM: in Motor Tuning I can not set steps per mm as I want to, cause else my motor wont move properly or not a bit...

The strange thing is 639.4 works 639.5 as well 639.6 doesn't and so on... Mach3 seems to be picky about the digits, which makes no sense to me...

When I do the procedure with the settings screen and "Set steps per Unit", Mach suggests me 638.3233533 and asks me if I want to store this value.
After I stored it, the motor doesn't move anymore.

I wanted to set steps per mm first before I start dealing with the backlash.
But when I tried to change it to x 0,01 for example, 100% speed,
checked backlash enable and set shuttle accel. in general config to 0.005 there was no effect on it.

What am I doing wrong?

Thanks for your help

Hi Matevž,

thanks for your help.

Since updating to the newest pokeys firmware everything works fine...

Okay I figured out the Problem with the Y-Axis.

I Got A steady X-Axis on wich the Z-Axis is adapted and A moving Table for Y-Axis.

When I want to move the drill relativ to the workpiece in positive Y the Table has to move towards me.

Okay Now X and Y work fine....but Z not yet...
It doesnt seem to matter if i change axis direction and homing direction...

Any help?

cheers Lukas
