For example.? I took a fairly new WIN-10 system that had been upgraded from WIN-7.? Even has MACH3 on it although I don't use it.

I plugged in an ESP32 DevKit1 and came up with the screen that shows it's got problems being recognized.? Unplugged it.

Next I went to the Arduino web page and downloaded the older 1.8 version of the Arduino IDE.

It downloads the .exe installer and then I answered yes to the various device drivers near the end.

When it was done I plugged in the ESP32 DevKit1 again and this time it shows up as COM5.

Now the device is recognized and likely MACH3 won't have a problem.

This is just a USB arduino connection...

How are you connecting to the MODBus?? A USB dongle that acts as a serial port or a physical serial port?

After WIN-7 Microsoft disallowed most USB PID combinations unless the owners paid $5k or so for the right to have their configuration approved.

Hi,

Trying to move my Mach3/Ess from Win XP to Win10, I get an "Error triggered" "Art Code 1" and "Art Code 9991" at the startup.
If I create a new profile by cloning my working profile, everything works fine the first start (even the Modbus logic) but the second time I get the error again.
If I uncheck "Modbus InputOutput Support" before Exiting evrything works as normal the next Start.

I reinstalled everything from scratch but still the same, seems to be a Modbus/Win10 problem...

Mach version is : 3.043.062

Any idea ?

Thanks.

Chris
