What causes "Weird signal from device" error?
« on: February 28, 2018, 05:08:45 PM »
I'm using a PoKeys57E with cnc4pc M16 board. Machine is a lathe. It works fine when it works but I often get this annoying error. Once I see it the machine then stops responding and then a "Connection with the device is lost" error comes promptly. The only thing left is to power-off/power-on 57E and restart Mach4.

I have checked all the wiring to make sure if I have a grounding loop but everything looks fine.

When I first get the 57E from cnc4pc it had v4.1.xx firmware installed. I then updated it to PoKeys v4.2.39 but nothing changed.

Anyway, what causes this error? Is there anything I can do/check?

Thanks,
Suat

By the way, I have tried the firmwares bellow but lathe encoder does not work with these firmwares so I stick with 4.2.39.

PoKeys v4.3.14 Configuration and PoBlocks (13.2.2018).exe (39.47 Mb)
PoKeys v4.3.6 Configuration and PoBlocks (3.1.2018).exe (39.41 Mb)
PoKeys v4.3.8 Configuration and PoBlocks (13.1.2018).exe (39.47 Mb)
PoKeys v4.3.9 Configuration and PoBlocks (16.1.2018).exe (39.54 Mb)
PoKeys v4.3.9a Configuration and PoBlocks (17.1.2018).exe (39.54 Mb)

Finally found the problem. It was the 20 cm wall type cat5 extension cable I use in the electronics box. When I remove it and connect pokeys directly to the computer (with a standard cable) everything is fine. I can't believe myself I didn't try this at first.
