ATC Compatible	Yes, Our spindle systems are fully upgradable to an Automatic Tool Changer. Checkout our latest Youtube video where Daniel is installing our ATC onto his Shapeoko 5 Pro CNC machine.	No
Programming Locked Down	No, we believe thoroughly in openness and transparency. It's your spindle system after purchase, you should have the ability to explore the features and expand functionality. VFD manual available	Yes, This protects you from accidental changes to the configuration.
Relocatable VFD Keypad	Yes (variety of mounting options available and uses standard cat5 computer cable) The ability to relocate your keypad allows you full control over your VFD and Spindle Motor.	No
Manual Override Switch (MOS)	Yes, Running your spindle in manual mode allows you to easily surface your wasteboard by jogging around. MOS allows you to control your spindle the same way you would a palm router.	No
Relocatable MOS	Yes (requires special 2-wire cable) This allows you to relocate the MOS alongside your VFD's Keypad.	No
Braking Resistor Port	Yes (plug-n-play braking resistor sold separately) Braking resistors allow your spindle motor to slow to a stop faster which improves your workflow and lets you pump out more products faster.	No
Shielded Spindle Cable	Yes (shielding prevents EMI interference with your stepper wires)	No
Machine Compatibility	Any / All machines We work very hard to provide compatibility with any and all CNC machines on the market. This allows you to easily switch machine brands and take your spindle kit with you.	Compatible with Shapeoko 5 Pro ONLY.
