CSlabs Mach3 plugin and Windows11

#1 · 9 July 2025, 09:41

mach3 runs perfect under Windows 11, but it seems that the CSlabs CSMIO/IP-S plugin (ver. 2910) does not work with windows 11 (latest versions). when starting Mach3 it a popup comes up with no connection.

I haven't personally used Mach3 in many years, but in general, the plugin should work. It’s possible that some older or obsolete Microsoft .NET Framework versions need to be installed manually. Do any pop-up windows appear when you start Mach3? Are there any warning or error messages?

It’s also possible that the plugin is working correctly, but Windows Defender or the firewall is blocking the connection. Recent versions of Windows 11 can be quite aggressive with this. Try temporarily disabling the firewall to see if that resolves the issue.
