Smoothieboard 5cX  is OpenSource, this means there are countless support sites and an entire community helping each other. OFFICIAL SMOOTHIEBOARD

The New !  1.1 version

  1. Upgraded stepper drivers to A5984 with 32x microstepping
  2. Added a solder jumper (JP36) for MS3 on new A5984 drivers
  3. Current limiting resistors (R78, R65-R68, R84-R85) changed for VBB powered LEDs to 8.2K
  4. Electrolytic capacitor (C84) added to the 5V power system
  5. The electrolytic capacitor (C63) for the 5x mosfet set has been moved and increased its footprint size
  6.  Flyback diodes (D7-D9) added to small mosfet outputs to protect from inductive loads like small fans
