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.

General Mach Discussion / Mach3 steps per mm ...some decimal places don't work

« on: January 25, 2015, 08:30:53 AM »

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

PoKeys / Wrong Direction Sending G-Gode, Jogging and homing works fine

« on: January 23, 2015, 08:56:44 PM »

Hi Guys,

I am nearly finished with my CNC-Mill and now got A Problem.

I'm using a pokeys 57E  with
Firmware 3.1.17
and Mach3 Version  R3.043.066

I was able to get everything started and Jogging and Homing works fine.

My X-Axis counts positive when jogging from left to right,
My Y-Axis counts positiv when jogging from front to back and
My Z-Axis counts negative when jogging from up to down.

When I send G0 X100 everything is perfect.
BUT, when I do the same with Y and Z axis, they want to go in the wrong direction.
As I'm using Pokeys I'm not allowed to change anything in Ports and Pins and MotorOutput.

I had to check reverse to Y and Z axis under Config...Motor Home/Softlimits to get the right counting wehn jogging.
I had to check Home neg. for Z axis. (see attached pic)

My scale right to the X Y Z axis says +1


Why is Mach 3 Jogging and counting everything correctly but moves the Y and Z axis in the opposite direction then g gode should move them?

Where is my fault?

Thanks for your help,

cheers Lukas

PoKeys / Pokeys 57E Need help getting started

« on: October 28, 2014, 09:29:20 AM »

Hi everyone,
I’m quite new to cnc stuff and got a problem with my system.
I’m not able to get the motors running (just holding torque).

System:
Pokeys 57E
Stepper Motor Driver DQ542MA (wantai kit)
(http://www.wantmotor.com/ProductsView.asp?id=257&pid=82)
Stepper Motor 57bygh627
(http://i1274.photobucket.com/albums/y439/michelle08070238/57BYGH/57BYGH627marked_zps435699b0.jpg)

I downloaded the latest Mach 3 Software and I’m running the 3.1.38 Pokeys Mach3 Plugin.

Therefore I copy and pasted the pokeys.dll tot he plugin-folder of mach3.
I activated it and just enabled under ports and pins the X,Y, and Z-Axis.
according to the Pokeys manual, thats all. Now I should get started with the motortuning, but nothing works.
When I connect the Pokeys to the PC and I test the pulse engine nothing moves.

At the wantais page you get two possible wirings:

1.   Pul + , Dir+ Enbl+ go to 5V and Step- Dir- go to the Controller (Pokeys)
Enable- can be left unconnectetd (enabled)

2.   Pul + , Dir+ Enbl+ go to the Controller (Pokeys)  and Step- Dir- Enbl- go to ground
Which wiring should I use?
At the moment I use the first wiring, because I read in here that it works like that.
When I give power tot he drivers, the green LED goes on and the red is out (allways, never had it on). The Drivers provide holding torque but dont move the motors.

When I’m in the Pokeys config menue under the toolbar „pulse engine“ an try to test movements, the green LED on the board starts flashing fast but nothing moves. When I close the Pulseengine setting the LED is on (stable).

What is my Problem?
Mach settings? Wiring?

Would be nice if someone could help me out here..

Thx Lukas
