[2026 New] FoxAlien 1.5KW VFD Spindle & PWM Smart Relay Module Bundle Kit

Best CNC Upgrade You Can Buy

My 4040 XE Pro was plagued with slow machining times and spindle / bit vibration that created chatter and significant finishing time for my CNC projects. I recently upgraded to the 1.5kW Foxalien spindle and I could not be happier. It is incredibly quiet, smooth, and provides the higher RPM needed to provide a glass smooth finish on my projects requiring little to no finishing. The significant reduction in machining time due to the higher feeds and speeds the spindle provides will more than pay for itself in a very short period of time.
