Title: PROBLEM WITH TANGENTIAL KNIFE
Post by: Cavalino on September 05, 2012, 09:34:34 AM

Hi to all..!!

First of all my apologies for my ugly english...
I have a CNC Router working fine with 4 axis, where A axis its angular and have a cutter blade as tool

The machine work very well and accurate, but the A axis rotate after Z is down with blade touching the material.
Any of you could to teaching mo to setup Mach3 to rotate the A axis before Z down?

Thanks to all.

Hi there,
try a negative Z axis value during cutting eg. ( Z -0.1 ) in your g code
not positive.
