Title: Z axis problem - Fusion 360 to mach4
Post by: carrotcruncher on May 23, 2022, 03:45:29 PM

Having issues with toolpath after post process and importing into mach 4, z axis decides to go down before x and y move to start point of cut - which looks to be the same depth. The actual 2d pocket function seems to be working correctly, just the move to the start position?
Hopefully something easy to sort - cheers ! Pic attached

That is a post issue in fusion, try using a different post, fanuc 6 mill may be better, there may also be an option on the post config screen to change the rapid move to xy then z

Hi,
Iv'e been using Fusion for two years with the Autodesk supplied Mach4 Post and I have not had issues like that.

Can you expand a little further and excerpt the Gcode that is at fault?
