Hi,
I'm currently using Mach 3 Turn demo and I'm just trying to see if I can get CSS(Constant Surface Speed) mode to work. I wrote up some example code that should let me see on Mach3 the spindle speed increasing as the X diameter decreases however the spindle speed is remaining at a constant 50 the whole time.
Could this be because I'm just running the code in simulation mode(I'm not hooked up to a real lathe with an encoder so I have no feedback) or is CSS mode a non-demo feature?
Here is the code I'm using, it should let me see the spindle speed increasing:
G21 G40 (metric and clear any comp.)
T0101 (select tool 1 offset 1)
G00 X100. Z10. (rapid to start point)
G48 S1000 (set max spindle speed)
G96 S50 M3 (select CSS)
G95 (set to feed/rev)
G01 X10. F.2 (feed to 10mm dia)
X100. (feed back to start point)
G97 S1000 M3 (set to rpm mode)
M30 (all done)
Thanks for your time!
