Water from either a hose or a bucket
Check: Are the gantry bellows covered in Abrasive?
Corrective Action: Clean abrasive off bellows with hose or bucket of water. After you’ve cleaned off the bellows you may find the water level is too high. Use the Maintenance > Quick Drain to lower the water level to the cutting bed.
Check: Do the Limit Switches work?
Root Cause: The extents of WAZER cutting area are managed by mechanical limit switches. With the machine turned off move the cutting head to each of the extents and listen for the quiet click of each limit switch.
