failing to locate cutting edge
Cause
• Old software installed
• Drill diameter is smaller than 3mm
• Drill diameter is of a smaller dimension
with a thick web
• Color of drill is interfering with cutting
edge detection – typically gold or black
drills Refer to page 61
• False diameter was input or detected in
• Fiberoptic Amplifier Baseline setting has
changed. Contact Darex for instructions.
manual mode
