PoKeys / Re: Pokeys 57E Need help getting started

Dear Lukas,
attached you will find my layout.

Kind regards,
Markus

PS.: To all: I do not guarantee for this circuit. Everyone is responsible for himself to check and - if necessary - to adopt it it before it is used within an electrical circuit.

Dear Lukas,
What you can try is to use one of the other pulse outputs but do not forget the pullup resistor.

The pokeys board cannot deal with high current. This is the reason why I have build up transistor switches for reach output.

Kind Regards,
Markus

Dear Lukas,

I have checked your setting of the pulse engine in the pokeys sw -> ok. So I have build up the system like you have done it (electrically) and I have set the same settings in the pulse engine of the pokeys sw -> it works.

There are two differences between your system and that I have build up:
1. The driver
2. I use the firmware version v3.1.17 instead of the latest version like you. I would suggest to download this version and try it again. Could be that this is the problem because I had also problems with the latest version.

Please try and let me know.

Kind regards,
Markus

Dear borisz,
I have downgraded the fw to v 3.1.17 and everything works fine! No problem anymore and also the emergency stop works correct (if I press it the motors stop moving).

So I suppose there is something wrong with the new fw.

Thank you very much for your support!

Kind regrads,
Markus

Hello borisz,
Thank you very much for your reply! If have:

1. removed the Pokeys SW by uninstalling it
2. removed mach3 SW by unistalling it
3. removed all folders and the PokeysMachConfig.xml from my personal Folder on my C drive
4. I restarted my Computer

Then I:
1. installed mach3
2. restarted my Computer
3. installed Pokeys SW
4. restarted my Computer
5. started mach3 and I have activated the pokys plug-in
6. restarted mach3
7. choosed my pokeys board
8. restarted mach3
9. started the pulse engine -> same Problem again: Motors are moving quite slow but moving

I have observed the following Points:
1. The emergency stop Input is wired correctly: If I press the button -> emergency stop, if it is release it -> not emergency and I can reset mach3
2. The motors are running EVEN the emergency button is pressed. If I release it and click reset in mach3 sw mach3 switches to normal operation and the motors are still moving with the same speed.
3. The Problem only occurs only if I start mach3. With the pulse engine of the pokeys sw it works perfect. If I have running mach3 even in the back ground and I start the pulse engine in the pokeys sw suddenly the motors start moving. If I close mach3 -> everything fine ...
4. The motor is moving quite slow. I measured the frequency and it's approx. 85 to 90Hz
5. Somethimes if I do some changes in the pulse engine but only in mach3 the frequency is changing and for a few seconds the Motors are running quite slower.
6. I have a second pokeys57E with a damaged emergency pin52 (I connected 24V DC to it -> RIP) but the pulse engine Outputs still working. This board has the older FW V3.1.17 and with this device it seems to work correctly (I have measured a frequ. of 1,6Hz but I suppose this is only because the value is quite low and out of the range of the multimeter). The emergency pin is always on so I have te3sted the new Installation with this board and the pulse engine works fine!

Question: How can I downgrade my new pokeys57E from FW V3.1.38 to V3.1.17? I suppose that the Firmware is the Problem ...

Thank your much for your Support!

Kind regards,
Markus

Dear Lukas,

1. Driver is working -> fine!

2. To test the pokeys Outputs with the LED is a good idea but be careful regarding the current! Due to the fact that the DIR Output is changing depending on the direction you jog we know that there is a communication and the outputs are switched. Depending the LED test on the PUL output: your Settings in the pulse engine create a frequency. If this freq. is more than 100Hz you will not see any flickering of a LED.

The next tests:

1. Do you have a multimeter which can measure frequency? If yes you can measure the frequency on the PUL Output. If you jog the axis there has to be a frequency which you can measured.

2. If you do not have a multimeter with freq. measuring function you can try the following: Set the Maximum Speed in the pulseengine of the pokeys SW quite low (approx. 1000 pulses/s) and try it again with the LED because the jog Speed 1% of 1000 pulses/s is 10Hz. So you should see the LED flickering.

3. If this will not work please can you post your Setting of the pulse engine (max. Speed, max. accel, max. decel., ...).

By the way: Have you connected the pin52 (Emergency Switch Input or have you inverted the Input? Because if you do not connect or invert the Input the pulse engine will not send pulses to the Driver.

Kind regards,
Markus

Dear Lukas,

May I suggest the following failure detection procedure:

First of all you should check if the stepper motor driver works without the pokeys controller. This can be done by using A frequency / pulse generator or you simply use a switch to generate some pulses. If this works the wiring of the driver is correct.

Second: You have to check the current which is consumed by the opto coupler of the driver. The pokeys outputs can only handle up to 4mA (Please see pokeys manual version 2/4/2014 page 24 - chapter 8.1). I also use the pokeys 57E and I use a transistor switch on each output to my motor comtroller. This has also the advantage that the 5V which are necessary for the driver have no influence to the pokeys board. Please be careful with the current: You can damage the pokeys board if the current is too high!

Third: Have you wired the correct pins to the motor controller? Please see the pokeys 'PulseEngine.1.pdf' on page 7. Also have a look on the circuit with the resistor! The pokeys board can sink or source outputs so the direction which you have choosen is correct.

Do you have the possibility to use an osziloskope? Than you can check the output of the pokeys board.

After you have checked all these hardware points we can check the software part.

I'm shure that you will solve the problem! Please let us know if you have solve it and what was the problem - thank you!

Kind regards,
Markus

Hello Matevž, hello eCraft,

I have the same problem with the new Pokeys Firmware and the mach3 plugin:

Due to the fact that I have damaged my old Pokeys 57E I bought a new one (so my system has already worked fine with mach3 and the pokeys 57E).

During the new hardware installation process I downloaded the new firmware and mach3 plugin. After I have installed and updated the pokeys device and starting mach3 all three axis started to run without any G-code AND an emergeny stop!

I have found this thread and I have already tried to solve the problem by removing and clearing all software you have mentioned below. I have reinstalled everything and the same problem again: If I start mach3 the axis start to move. If I close mach3 and if I try to jog the axis via the pokeys sw (Pulse engine) everything works fine - no problem. If I start mach3 same problem again.

Mach3: R 3.043.066
Pokeys FW: V 3.1.38

Do you have any idea what could be wrong? I do not think that this is a hardware problem because:
- The system has already worked
- I have no problem with the pulse engine sw from the pokeys sw
- The problem starts and stops by starting / stopping the mach3 sw

Kind regards,
Markus
