[QUOTE=BehemothDT;2319064]Shineworld, do you have the tool diameter loaded in tool table for tool 120?
Yes, I've used a tool diameter of 1.2 in.
To use 1.25 in I need to change G41 mode from Normal to Easy Lead In mode otherwise the g code compilator sign "Cutter gouging with cutter radius comp" error.
In RosettaCNC is possible to define 3 types of G41 compensations strategies: NIST, Easy Lead In and Normal (the default mode).
Every mode manage differently the gouging questions.
For CAM like Fusion 360 Easy Lead In is the right way.
For manual gcode is better to use Normal way in which gouging is managed better
NIST mode is the more strict way and implement the NGC274D-NIST standard.
