I'm having an issue getting a 4 axis post set up for my Toshiba BTD-200QH boring mill, Tosnuc 999 control. I'm not sure exactly what to call this type of positioning, so I'll try to explain how it works. The machine reads the table position 0 through 359.9999 degrees. There are no negative values on the readout and it can rotate without hitting a limit. The program syntax, however uses a negative value to control the direction of travel but its always an absolute value of the table position.
For example:
N1 G0 B45. :moves to B45 in plus direction
N2 B44. : moves to B44 in plus direction travelling 359 degrees
N1 G0 B45. :moves to B45 in plus direction
N2 B-44. : moves to B44 in minus direction travelling 1 degree
Both end in the same place but the former does almost a complete revolution. For positioning work this won't kill me, but you can just imaging the carnage cutting simultaneous when the program would want to move in a negative direction.
Has anyone seen this on any other machines or have any idea how to get the correct syntax for this rotary motion from the post? I've used most main stream conrolls and this is the only thing I've seen run like this. I have seen this output as an option in IMSpost, but I can't find it in fusion. Any help is greatly appreciated and I will gladly share when its completed.
