Actions to be done

  • Make holes to be able to tighten anti-backlash nut in side bracket
  • Mount the T-Slot table
  • Square up the whole setup
  • Shim the T_Slot table to have the X-Axis parallel
  • Mount the Y-Axis to give rigidity to the CNC
  • Flash Arduino
  • Connect power supply 36 V
  • Connect Motor drivers
  • Electrically connect Arduino to Motor drivers (X-Axis)
  • Drive both X-Axis to center ish position
  • Align the anti-backlash nut to be dead parallel to rail
  • Mount two X-Asix motors (plates)
  • Put grease on the X-Axis with a brush
  • Align both X-Asises by moving it and tightening the bolts in correct allignment
  • Find a better way to control CNC
  • Beagle bone black, connect and see if that works with LinuxCNC or UCCNC
  • Create spray booth (clean room)
