Hello everybody,
I´ve just finished my setup and try cutting machine with Mach 3+ TNG with rotary plasma plugin.
I have set in POST one revolution is 360... i know, it takes as linear axes... but i have set mototors to 360 is one revolution... So coordinates are OK, bud problem is cutting speed, do you have same ideas how to set speeed for axis A.... because i have ery good linear speed which works... But problem is in diameter in axis A... How I can drive this parameter? because Speed on diameter is depend on diameter... I have to chanfe every time set for axis A in Mach or i can edit post for this?

Sorry, I missed this question. The post takes care of cutting speed and diameter compensation.
In my experience, Mach3's path planner works better if the rotary axis is set to 1 unit per revolution rather than 360. If you change this in Mach you also need to change it in the post.
