Hi Tom!
First I want to Thank You for your support in helping to solve this.
I got my spindle under control with following:
#include "KMotionDef.h"
//Plugin Notifications and defines..
enum { EX_DDA , EX_VMS, EX_COMMAND, EX_SPINON, EX_SPINOFF, EX_SPINSPEED, EX_MOTORTUNED
, EX_SETUP, EX_FEEDHOLD, EX_RUN, EX_ESTOP , EX_CONFIG };
#define SPINDLE_AXIS 3 // axis set up as Spindle, possibly Step/Dir or Servo
#define FACTOR 226000.0 // Converts fractional pulley speed to counts/sec (may be negative)
main()
{
int message = persist.UserData[0]; // Mach3 message ID
int Direction = persist.UserData[1]; // Mach3 Spindle Direction
float speed; //= *(float *)&persist.UserData[2]; // value stored is actually a float
int DirFactor = 0;
//if (Direction==0) DirFactor=-1; // change Direcion 0 or 1 to DirFactor -1 or +1
if (Direction==0)
{
DirFactor=-1;
printf("Spindle CW ON\n");
}
else if (Direction==1)
{
DirFactor=1;
printf("Spindle CCW ON\n");
}
printf("Mach3 Notify Message=%d, Direction=%2d, Spindle Set to %f\n",message,Direction,speed);
switch (message)
{
case EX_SPINSPEED:
DefineCoordSystem6(0,1,2,-1,-1,-1);
speed = *(float *)&persist.UserData[2]; // value stored is actually a float
printf("Spindle Speed Set to %f\n",speed);
Jog(SPINDLE_AXIS,speed*FACTOR*DirFactor);
while (!CheckDone(SPINDLE_AXIS));
break;
case EX_SPINON:
if (Direction==0)
{
DirFactor=-1;
printf("Spindle CW ON\n");
}
else if (Direction==1)
{
DirFactor=1;
printf("Spindle CCW ON\n");
}
//Jog(SPINDLE_AXIS,speed*FACTOR*DirFactor);
break;
case EX_SPINOFF:
printf("Spindle Stop\n");
DirFactor=0;
Jog(SPINDLE_AXIS,0.0);
while(!CheckDone(SPINDLE_AXIS));
DefineCoordSystem6(0,1,2,3,-1,-1);
break;
}
Jog(SPINDLE_AXIS,speed*FACTOR*DirFactor);
while(!CheckDone(SPINDLE_AXIS));
}
It may well be that this is not the most elegant solution but it works:
-Spindle speed and speed changes on the fly OK
-Both M3/CW and M4/CCW OK
-Manual Jogging OK
-controlled motion (G0 A90 etc.) OK
Only small beauty flaw is that if I enter spindle speed manually after Mach startup the spindle will start without activating the EX_SPINON. I need to set the rpm to 0 to stop the spindle and click spindle start twice. After that it works.
I see Steve is also struggling with the mach spindle. I don't know if this helps, but it's one possible solution.
Rgds,
Tapio
