The Panucatt Azteeg X3 PRO is a fantastic contoller that provides support for 8 stepper drivers and up to 5 extruders (if you dare). This controller is very similar to the X3 controller board which is commonly used by 3D printer manufacturers. The X3 PRO is powered by the Atmel ATMEGA2560 micro controller chip and is designed with excellent high current capability. The controller is compatible with most firmwares.
The possibilities are almost limitless with the Azteeg X3 PRO from Panucatt. The Dual Heatbed Mosfets (single control) provides you the flexibility to run multiple heatbeds and also provides 3 separate inputs and fuses which means it will cover most power input configurations out there.
Digital Pot stepper current control can now be achieved on plug-in drivers using the SD8825 stepper drivers on the X3 PRO
