Fadal rotary axis positioning error in mastercam

[qiang601]

hey guys,

 

I really need a help for Fadal VMC4020 rotary axis, the G-code from Musatercam the A axis totally off about 90 degress.

Please Help!

This is most likely that you're using axis substitution and your geometry is out of sync causing the location to be off 90°

 

The other thing to check is in the machine def, make sure the 0 position for the rotary is Z+

 

Either one or possibly both of those are at the center of your issue more than a post issue.

If you are performing a cut on the side of a part, ensure that the WCS and tool plane do not use the same planes, otherwise you will get no rotation. The wcs represents how the part is sitting in real world coordinates, the tool plane is used to control the tool vector for simple 3-axis cuts.

 

We really need to know what kind of operation you're programming with to determine what the issue is...

thanks for helping,

i find out one problem with G-Code

 

 

N10 G20

N12 G0 G17 G40 G80 G90

N14 ( SHELL MILL TOOL - 1 DIA. OFF. - 1 LEN. - 1 DIA - 3. )

N16 T1 M6

N18 A-0.

N20 G0 G90 S4500 M3 E20 X-4.865 Y1.5

N22 H1 Z1. M8

N24 Z.2

 

A-270

A-90

 

 

G90 and A-0 that is wrong, because G90 only for absolute values can't be negative number .

how can i change A-0 to A0 in Fadal Format_2 4X Mill.pst? please helps
