SMINTx6 is a 32 bit motion controller for all kind of CNC machines. It is based on open source smoothieware and it is compatible with smoothie board in basic functionalities.
SMINTx6 is equiped with the new version of Allegro stepper drivers A5984 supporting 1/32 step mode and new APED algorithm for less vibra­tions, increased step accuracy and less audible motor noise.
Furthermore, there are six stepper drivers on the board, three for XYZ axes and other three can be used for multiple extruders or additional axes on the CNC machine. Two out of six FET driven power outputs have optionally independantpower supply connection. This is useful if you need to mix 12V and 24V heaters, vents,pumps etc. A 5V regulator on the board allows the user to select between 3.3V and 5V supply for end switches or sensors. The PCB layout is optimised for better thermal dissipation and there are mounting holes for heat sink ner stepper drivers and FETs.
For future options there are prepared headers for SPI, 12C and UART, which allows advanced users to easily add new hardware like display pannel, WiFi module, temerature sensors etc.
