Yes, that's what I saved it as.

Yes, I't responds the same way by not deactivating Bit 159.

I'll clear those parts.
My Spindle Deffinitions:
Code:
#define SPINDLEAXIS 7 // Axis Channel to Jog to rotate Spindle
#define FACTOR (10000/60.0) // to convert RPM to counts/sec (counts/rev / 60.0sec)
#define SPINDLECW_BIT 154 // bit to activate to cause CW rotation
#define SPINDLECCW_BIT 155 // bit to activate to cause CCW rotation
#define SPINDLEBREAK_BIT 157 // bit to activate/deactivate spindle break
#define SPEEDVAR 99 // global persistant variable to store latest speed
#define STATEVAR 98 // global persistant variable to store latest state (-1=CCW,0=off,1=CW)
#define KMVAR PC_COMM_CSS_S // variable KMotionCNC will pass speed parameter (113)
#define USE_POS_NEG_VOLTAGE 0 // 0 = output Magnitude, 1 = output positive and negative speed
This code is used to ClearBit (activates) and SetBit (deactivates) the spindle break (Bit157).
Code:
#include "KMotionDef.h"
#include "MySpindleDefs.h"
// desired speed is passed from KMotionCNC in variable KMVAR
// save in user variable STATEVAR whether it was off, CW, or CCW (0,1,-1)
// save in user variable SPEEDVAR the last desired speed
main()
{
// spin down
ClearBit(SPINDLECW_BIT);
ClearBit(SPINDLECCW_BIT);
ClearBit(Coolant);
Delay_sec(0.5);
ClearBit(SPINDLEBREAK_BIT);
printf("Jogging Spindle Stop\n");
persist.UserData[STATEVAR] = 0; // remember we are Off
while (!CheckDone(SPINDLEAXIS)) ;
}
lets me turn on spindle CCW
Code:
#include "KMotionDef.h"
#include "MySpindleDefs.h"
int *css_mode = &persist.UserData[PC_COMM_CSS_MODE]; // Mode 1=Normal RPM mode. 2=CSS
// desired speed is passed from KMotionCNC in variable KMVAR
// save in user variable STATEVAR whether it was off, CW, or CCW (0,1,-1)
// save in user variable SPEEDVAR the last desired speed
main()
{
float speed = *(float *)&persist.UserData[SPEEDVAR]; // value stored is actually a float
float LastState = persist.UserData[STATEVAR]; // get last state
if (LastState==1)
{
// if spindle was CW now we want CCW
// spin down
ClearBit(SPINDLECW_BIT);
ClearBit(SPINDLECCW_BIT);
Jog(SPINDLEAXIS,0);
while (!CheckDone(SPINDLEAXIS)) ;
}
// turn spindle on CCW and ramp to new speed
SetBit(SPINDLECCW_BIT);
SetBit(SPINDLEBREAK_BIT);
LastState = -1;
persist.UserData[STATEVAR] = -1; // remember we are CCW
}
Lets me turn on Sindle CW.
Code:
#include "KMotionDef.h"
#include "MySpindleDefs.h"
int *css_mode = &persist.UserData[PC_COMM_CSS_MODE]; // Mode 1=Normal RPM mode. 2=CSS
// desired speed is passed from KMotionCNC in variable KMVAR
// save in user variable STATEVAR whether it was off, CW, or CCW (0,1,-1)
// save in user variable SPEEDVAR the last desired speed
main()
{
float speed = *(float *)&persist.UserData[SPEEDVAR]; // value stored is actually a float
float LastState = persist.UserData[STATEVAR]; // get last state
if (LastState==1)
{
// if spindle was CW now we want CCW
// spin down
ClearBit(SPINDLECW_BIT);
ClearBit(SPINDLECCW_BIT);
Jog(SPINDLEAXIS,0);
while (!CheckDone(SPINDLEAXIS)) ;
}
// turn spindle on CCW and ramp to new speed
SetBit(SPINDLECCW_BIT);
SetBit(SPINDLEBREAK_BIT);
LastState = -1;
persist.UserData[STATEVAR] = -1; // remember we are CCW
}
