| Do ✅ | Don’t ❌ | |---|---| | Power off the CNC machine and disconnect the USB cable. | Never run the CNC machine with a partially installed driver. | | Create a backup of your working Mach3 configuration (the .xml profile). | Do not copy the RnRMotion.dll into C:\Windows\System32 – it belongs only in the Mach3 Plugins folder. | | Temporarily disable antivirus software that might quarantine the DLL. | Avoid using “driver updater” tools; they often install the wrong driver. | | Work on a stable system – do not run other software while updating. | Do not use a USB hub; connect the BSMCEO4U‑PP directly to a USB port on the computer. | | If possible, use a dedicated computer for CNC work without extraneous security software. | Do not skip the required reboot after copying the DLL. |
