Hello,
I'll setup all the home switches, motors, probe, and emergency stop in Pokeys and Mach4. Everything works fine. When I close Mach4 and come back to launch Mach4, I'll get a message showing Pokeys communication error. I check the communications in Pokeys software and it is working fine. In order to get communication working in Mach4, I have to power off and on the Pokeys board. Relaunch Mach4 and all the setting in Pokeys are gone. I have to reenter all info in Pokeys. Everything works fine. Close Mach4 and I have to repeat the above process.
I'm using the latest Pokeys/Mach4 plugin and Pokeys firmware. Running Windows 7 software.
Could someone please help!

Thanks,
Kerry

I found another post saying that he used the Ethernet cable instead of the USB to control the Pokeys. So, I decided to try the Ethernet cable and it has be working good. No lost setup parameters so far.
I'll post back in about a week with my results.

Using the Ethernet cable is still working great. No more losing data in Pokeys setup.
