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

Hi Markus,

thanks for your help.

IT WORKS!!!!!!!!!!!!!

I used the 3,3V output instead of the 5V and connected it to PUL+ (+5V) and DIR+(+5V).
Then PUL- to Pokeys [PIN46 ,..............PIN 48 & 49 with 470 Ohm resistor]
DIR- to 38;39;40 on Pokeys.

Suddendly it worked.

When I used 3.1.38 Firmware the Motors started althought the Emergency-switch was activated while starting Mach 3.
I downgraded to 3.1.17 and everything works fine...

The Driver seems to be okay with 3,3 V instead of the discribed 5V.

Took me all my nervs but now I can go for my mechanical setup.

Cheers Lukas

Hi markus,

how does your setting (electrical) look like?

What drivers are you using?

How do I install transistor switches?
Can you post a picture?

Yeah maybe you are right, I tried it just with the x-axis, cause there I dont need the pullup resistors...
I'll try it tomorrow with the Y and Z axis...

I found out that Pokeys is installing stuff all over my pc... tried to delete everything befor I installed the latest firmware again...

Actually I dont need to Install Mach3 everytime, cause at first the motors should move with the pokeys SW, right?

Hey Markus,

I tried what you suggested me to do, but it didn't work.

I tried it with the Driver connected and I tried the LED test --> LED is always on.
The strange thing is, that when I try to invert or inactivate the PIN 46 the LED is still on... only if I reset the Pokeys I can put it as Digital Output or click inactive and the LED goes on or off.

I also tried a diffrent Power supply (meassured 5,12V).

Could it be that my Pokeys is broken?
I mean, from my side it seems not to be able to send pulses...

I'm pretty annoyed and don't know what to do...
I reinstalled mach an pokeys several times...

I uninstalled mach and Pokeys and tried everything with the firmware 3_1_17 and 3_0_65 as well...

Thank you for your help.

Is there something else that I could test?

Thx Lukas

Hi Markus,

unfortunately I don't have a multimeter which can meassure frequency...

so I just did, what you advised me to do under point 2, but still got no flickering...

Yes I have connected pin 52 to ground...


I post my settings as attachment.
Mach 3 should be uninteresting for the moment, cause I think at first I should get it going with the pokeys config program...

Thanks Lukas

Hi Markus,

I tested the Driver:

I connected Power to the Driver...
Connected +5V to .....PUL+(+5V), DIR+(+5V) there is no reason for ENBL, because it is enabled without 5V
For testing I touched Ground to the PUL- (PUL) and the Motor stepped.
So, the Drivers work.

I tested Pokeys:

I connected a LED to x-DIR (PIN 36) and 5V on Pokeys...
When I start the Pokeys Configuration Program the LED in ON,
and when I go under Pulse engine settings, at the beginning I always have to unlock the pulse engine.
When I press RUN and move the x-Axis, the LED is on or of, depends which direction I move [I think this should be fine].
Meassurement with the multimeter is 4,84 V in one direction and something about 1,8 in the other direction.
The Power supply for Pokeys is a USB charger with 1A output..should be enought...

When I do the same procedure with x-STEP (PIN 46) the LED is ON, even when I'm not connected to the config-program or mach3...
when I enter the config program and move the axis its always on...I thought I'd see the LED flickering, but it seems stabel....maybe a tiny tiny flickering, but everytime (eben when I dont move the axis).

The ON OFF switching of the LED (5v and X-DIR) works with Jogging in Mach3 as well.


I have no osziloskope, so what else can I do?

Could it be a Timing Problem?



Driver DM542MA

Step Time         Step Space         Direction Hold         Direction Setup          Steps on

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
