Currently, I have motion problem as shown in video clip below. I use Mach3 R3.043.066 with pokeys57E plugin v3.1.42 and v3.1.17.
The motion path would jump off G-code path and step signal was also jerking, the problem can happen at any time, sometime I could run G-code cross.tap for 2 or 3 times before symptom arrive.
I use External 4ch without IO and with other features like LCD, PWM, Encoder and PoExtBus
I tried to locate the bug by changing configurations such as
- change plugin version
- change notebook computer
- change OS between Windows 7 and XP
- turn on and off LCD, PWM, and Encoder
So far I have no luck.

How do you have your network configured? Open PoKeys status window (there is a button for IO status window in plugin settings) and observe the progress bar below - does it stay green?

I set them as fixed ip address, computer is 192.168.123.12, Pokeys57E is 192.168.123.13 both subnet mask is 255.255.255.000

Is there any other application accessing the device at the same time?
-
Nop, only mach3 and Pokeys Plugin is running on the notebook computer.
I also did a clean up as suggested in http://www.machsupport.com/forum/index.php/topic,28213.0.html
I also did a fresh installation for mach3 and Pokeys software on new notebook computer and it gave same problem.
However, I might try them on desktop computer. I don't know what environment of this plugin is developed in, which made software behaves differently between yours and mine.

What speeds have you configured in Mach3 motor configuration?
-
steps per unit is 2500
velocity is 1600
acceleration is 300
I connected a servo driver to y axis and put it on workbench, rather on real machine.
-
Did you try doing a dry run (without the drivers attached)? Is PoKeys connected to a network or are you using a direct connection with your PC?
We executed more than 10 consecutive runs of the same file now and there were no issues.

Hi Matevž,
I think I found a suitable environment for Mach3 R3.043.066 and Pokeys57E plugin v3.1.42. below was an experiment that I did.
I went to my desktop computer, installed all needed software and tried them. After several testing, there's NO symptom of bad motion. I noticed that PC has only single network card.
I came back to my previous two notebooks and disabled wireless network then tried them. Surprisingly, I found a solution. (at least for the time being)
At this point, I think that the sub-network of wireless is different than other two devices and causes the problem. Or there are some of other things which I don't know and I hope that you guys can find out and solve it permanently.
I connect Pokesy57E directly to Ethernet port with single cable, not through switching hub.
Yes, mostly I do the dry run, I have 2 LED attached to show step/direction signals, there is no interference issue.
thank you,
Weerasak
