Lathe spindle speed mods

[gcode]

We've got a new Toshiba VTL that requires an extra 0 at the end of the spindle speed

in other words

S500  needs to be S5000

The spindle clamp needs the extra zero as well

I've modified my post like this

pcssg50         #Output Constant surface speed clamp
      maxss = (maxss * 10)
      if css_actv$, pbld, n$, *sg50, *maxss$, pgear, e$

pcss            #Output Constant surface speed
     
      speed = (g_speed * 10)
      if css_actv$, pbld, n$, *sg9697, *speed, *spindle_l, !css_actv$, e$ # force M3?? 07-20-07
      !speed

 

this is the result

In Mastercam the spindle clamp is  programmed to 200

CSS is programmed to 500

desired output is

2000

and

5000

this is what I'm gettting

 

M6 T100
M0
G0 G54 X30.439 Z6. T0101
G92 S200 M42  <----------------- this is unchanged  ( G92 = G50 on this machine)
G96 S5000 M3   <----------------  this is correct
Z2.2775
G99 G1 Z2.1775 F.018 M8

 

can some one steer me in the right direction

Check your formula. The output variable is 'maxss$'. (You forgot the dollar sign...)

[gcode]

That worked,

but I'm curious as to why the $ was not required

on the 

speed = (g_speed * 10)  line

 

 

pcssg50         #Output Constant surface speed clamp
      maxss$ = (maxss$ * 10)
      if css_actv$, pbld, n$, *sg50, *maxss$, pgear, e$

pcss            #Output Constant surface speed
     
      speed = (g_speed * 10)
      if css_actv$, pbld, n$, *sg9697, *speed, *spindle_l, !css_actv$, e$ # force M3?? 07-20-07
      !speed

The '$' is only used for pre-defined variables. 'speed' is simply a user defined variable. It's value is set elsewhere in the Post, using either a function or formula.

[Colin Gilchrist]

The 'maxss$' value is entered inside the dialog box in Mastercam. The 'speed' value is calculated and set in another Post Block, since you can be in either RPM or CSS mode, and it outputs through the same output variable.
