hi, I am trying to make the 4 axis work Simulantouse with ZXY..
its A drive and I have made some progress but i am stuck at the moment..
I have made the A axis on the parrametes page to be Multiturn to Effective..
my issue is that some code it works and some code it doesnt..
and I dont know why..
here is sample of code..maybe i am doing something wrong..would anyone be able to supply me some sample Gcode i can use or try on 4 axis for okuma machine?

So this code goes round and round (like 4axis head keep turning full circles)
N1 G0 G94 G15 H20 A.017 M16 X10.981 Y0. S15000 M3
G56 Z200. H2
Z75.
G1 Z65. F500.
X10.998 A348.857 M15 F2000. (this line here makes the 4axis head go full circle from A.017)
X10.953 A348.399 (this line goes another circle)

While the this code doesn’t..it goes Cw and CCw simulatnouse which is what you excpect.

N1 G0 G94 G15 H20 A0. M15 X-1.031 Y-46.9 S15000 M3
G56 Z200. H5
Z150.
Z62.991
Z52.991
G1 Z42.991 F1000.
Y-45.57 Z44.577 A1.97 F8000. M16
Y-44.186 Z46.123 A3.939
Y-42.711 Z47.653 A5.961
Y-41.183 Z49.136 A7.982
Y-39.589 Z50.571 A10.021

Is there somethere in the parramets what when I change to 4axis multi turn to Effective something other parrametrs that change as well automatically?

Not sure of the correct parameter
- but you need to activate the "Shortest path"

Your use of M15 / M16 forces the axis to rotate in one direction only, so if machine at A0. & you program A-1. M16 ( = 1° movement), but A-1 M15 would be 359° movement )
- if you program shortest path, try omitting the M15 / M16 codes

There should also be a setting to stop the count over 360°
- normally any wind-up of the axis, has to be un-wound, & ( I think ) maximum # of rotations is 25 ( 9000° )
- so A720° will still do 2 rotations

would it be M403 #69 BIT 0 ?

ok I sorted out, need testing still, but 4 axis is working now..
the Multi turn didnt help much I disabled it, and I enabled short path M403 in parameter 69. bit 0
