We’re sure you’re itching to start cutting! Before you begin making chips fly, we recommend going through these final checks to ensure you are set up for success.

Mechanical

  • All screws in the table frame have been tightened
    • End plates with T-nuts
    • End plates to Y rails
    • Crossbeams to Y rails
    • Clamping nuts on levelling feet
    • Legs to frame
  • Table is level on all 4 corners of the machine
  • All couplers have been fully tightened on both the motor shaft and ballscrew sides
    • You may need to unfasten from the ballscrew side to check the motor shaft side
  • Grease has been applied to the gear rack

Electrical

  • Motor DIP switch positions are correct for each axis

X and Y-axis motor, from 1-5: OFF, OFF, OFF, ON, ON

Z-axis motor, from 1-5: OFF, OFF, ON, ON, ON

  • Motor cable wires are not frayed or detached from connectors
    • If they are simply detached, you can use a small screwdriver to press each orange spring terminal release to insert the wire back in
    • You may need to remove the motor cover to check
  • Inductive sensors are functional
    • Check by putting a metal object near the blue sensor face and see if a small red light triggers on the back
  • Spindle VFD is plugged in to a separate circuit from the SLB-EXT control board

Software

  • You are using gSender version 1.6.0 or newer
    • Older versions of gSender do not support the ATC
  • Alarm 10 can be cleared using the “Click to Unlock Machine” on gSender, after pressing and releasing the E-stop button

  • Machine can jog in the X, Y and Z directions smoothly using the jog control buttons
  • Machine can jog over the table joint without any clunking sounds
  • Spindle can spin up to speed, without alarms or errors, using the CW or Forward button

  • Machine is able to successfully home without alarms or errors
    • Jog the machine away from the X, Y and Z sensors
    • Then press “Home”

If you have gone through the checks above, then you are ready to start cutting!
