Threadmilling cycle on Centreline posting C-Axis movements.

[milling1UELAX]

hi guys, trying to thread a pretty standard thread in inconel on centre line by threadmill cycle. However when using the Mori NLX Millturn post provided by Fusion 360 itself, when posting out the NC code it utilises the C-Axis which I do not want. How do I stop this from happening and use X,Y,Z movements with the turret?

Your post properties will need to be adjusted to permit the X axis to go below centerline.

Take a look either in the code or at posting time for this:

xAxisMinimum: {

    title      : "X-axis minimum limit",

    description: "Defines the lower limit of X-axis travel as a radius value.",

    group      : "configuration",

    type       : "spatial",

    range      : [-99999, 0],

    value      : 0,

    scope      : "post"

If you set it to a negative value, it will use XZY motion

Hi seth, I'm looking at these lines specifically in the Post and they are exactly as you typed, do I make the "Value" less than zero?

Yep! For my Doosan Lynx, I've determined that for most main-spindle work, I can safely go to about -18mm below centerline, provided that my part is less than ~60mm extended from face of chuck. After that, all bets are off....

Okay so the "Value" line changed nothing for me however when I adjusted the 

range      : [-99999, 0],

to

range      : [-99999, 99999],

This actually worked, thank you for pointing me in the correct direction Seth!
