Yes i am trying to add a call for a manual gear change to my
centriod post mc8. something like an if statment.
If speed is < than 2500 post comment
"M0 (CHANGE TO LOW GEAR)"
IF speed is > than 2500 post comment
" M0(CHANGE TO HIGH GEAR)"

I am runnuing a BP series 2 with inverter and a manual switch to change from high to low which changes the spindle direction ,but would like a statement with a M0 to make the changes

Thanks Brad

If your conditional statements (if speed etc) work on the Centroid (or should it be 'if S' ?) and anything between the " " is a comment then I would say that the M0 has to be outside of the comment string to work.

Al thats what i dont know how to write
it should work ,and I can put the M0 just before after it?
this is the post ihave been messing with
*progno, e
"(PROGRAM NAME - ", progname, ")", e

any ideas?

if speed <= 2500, n, "M0 (CHANGE TO LOW GEAR)", e
if speed > 2500, n, " M0(CHANGE TO HIGH GEAR)", e
n, speed, *spdlon

I think if you add 2 lines it will work as you wish

I think what you want to do to compare the next spindle speed with the current spindle speed and if a high/low range is required, then output your M0 and comment. Otherwise you are going to get a "spindle speed high/low" at each speed change when you don't require a range-change.

Put this in ptlchg before the spindle output
"Tested in version 9"

if speed >= 2500,
[
if prv_speed < 2500, "M00", "(CHANGE TO HIGH GEAR)", E
]
if speed < 2500,
[
if prv_speed > 2500, "M00", "(CHANGE TO LOW GEAR)", E
]
