On the ethernet adaptor interface (now named “SmoothStepper Network XX”), disable all protocols except Internet Protocol Version 4 (TCP/IP v4)
In the ethernet adapter properties, under the “Advanced” tab, disable the “Energy Efficient Ethernet” and “Green Ethernet” properties (Note: either or both of these properties may not exist).
In the ethernet adapter properties, under the “Power Management” tab, uncheck “Allow the computer to turn off this device to save power” option (Note: the Power Management tab may not exist, in which case skip this step).
Turn off/disable the Windows screensaver.
Configure Power Management - create a new power plan called “CNC”, starting with the “High Performance” as the template, and set everything to “Never” for both the “Plugged In” and “On Battery” settings (Dim Display, Turn off Display, Put Computer to Sleep).
NOTE: You must go into the “Change advanced power settings” to configure the Hard Disk to never turn off (on battery or plugged in).
Disable (preferably uninstall) any third-party virus scanning/protection software.
Configure Windows Defender (Windows 8 ) / Windows Security Essentials (Windows 7) to never run a scheduled scan (note: this is not possible on Windows 10).
Configure Automatic Updates:
If you are running Windows XP, Vista, 7, or 8, disable automatic updates altogether.
If you are running Windows 10:
under Advanced Options, set the “Choose how updates are installed” setting to “Notify to schedule restart”
check the “Defer Updated” checkbox (if present)
Create a shortcut to run Mach3 with “Above Normal” priority.
You can download one here: Mach3 Loader (Priority) Shortcut (save it to your desktop), or create a new shortcut on your desktop manually and edit the following settings:
Target: C:\Windows\System32\cmd.exe /c start "Mach3" /AboveNormal "Mach3.exe"
Start In: C:\Mach3
Optionally, set the shortcut icon by navigating to "C:\Mach3\Mach3.exe" and selecting the Mach3 icon.
Drag the new shortcut to the task bar to pin it there for convenience.
Always turn-off or disable all other network connections (i.e. Wifi) when running a CNC program in Mach3.
Check Windows Task Manager for other processes taking up significant CPU or Memory resources.
