No :)

You've included CSSJog.c and also pasted its contents. Only Include it.

You have 2 main() functions. There must only be one. main() is where the program starts. There can be only one starting place for a program.

Code is incorrectly indented making it hard to understand or read. Use Auto Indent to clean it up.

gotcha
Can grounding the E stop from the servo amp to the electronics case bring in noise?
getting some nice run off on Z axis in the Z negative direction only
even after the MaxFollowingError=5000 trips
X axis works great

Re: idk why lathe changes

Post by turbothis » Wed Mar 06, 2024 9:31 pm

ok i got the spindle performing well
the only issue is i have to double push the CW/CCW buttons to work

which ever button i push first is the way it will rotate. (first push does nothing but pick which way to rotate)
the second time i push one of the buttons it will turn on spindle. ( this can be either CW or CCW as the first button push locks in which direction to rotate)

my CW

Code: Select all

#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 
	int LastState = persist.UserData[STATEVAR];  // get last state 

	if (CS0_axis_a == -1 && !ch2->Enable)		// is A axis not defined in the Coordinate System and not enabled?
		EnableAxis(2);			// yes, enable the axis

	
	if (LastState==-1)  
	{
		// if spindle was CCW now we want CW 
		// spin down
		
		ClearBit(SPINDLECW_BIT);
		ClearBit(SPINDLECCW_BIT);
		Jog(SPINDLEAXIS,0);
		while (!CheckDone(SPINDLEAXIS)) ;
	}
	
	// turn spindle on CW and ramp to new speed
	SetBit(SPINDLECW_BIT);
	
	
	LastState = 1;          														 //  Add string
	
	
	if (*css_mode != 2)
	{
		// spindle is already on, so ramp to new speed
		if (USE_POS_NEG_VOLTAGE)
			Jog(SPINDLEAXIS,speed * FACTOR * LastState);
		else
			Jog(SPINDLEAXIS,speed * FACTOR);
		printf("Jogging Spindle %f counts/sec\n",speed * FACTOR);
	}
	persist.UserData[STATEVAR] = 1;  // remember we are CW
}

my CCW

Code: Select all

#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 
	int LastState = persist.UserData[STATEVAR];  // get last state 
	
		if (CS0_axis_a == -1 && !ch2->Enable)		// is A axis not defined in the Coordinate System and not enabled?
		EnableAxis(2);			// yes, enable the axis
	
	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);
	
	LastState = -1;
	
	if (*css_mode != 2)
	{
		// spindle is already on, so ramp to new speed
		if (USE_POS_NEG_VOLTAGE)
			Jog(SPINDLEAXIS,speed * FACTOR * LastState);
		else
			Jog(SPINDLEAXIS,speed * FACTOR);
		
		printf("Jogging Spindle %f counts/sec\n",speed * FACTOR);
	}	
	persist.UserData[STATEVAR] = -1;  // remember we are CCW
}


my jog

Code: Select all

#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)

	int  LastState = persist.UserData[STATEVAR];  // get last state 
	
	persist.UserData[SPEEDVAR] = persist.UserData[KMVAR];  // Always save the last desired speed 
	
	if (LastState==0 || *css_mode == 2)  
	{
		// if spindle is off (or CSS mode) and User Changes the speed 
		// just save the desired speed
		
		return 0;
	}
	
	// spindle is already on, so ramp to new speed
	if (USE_POS_NEG_VOLTAGE)
		Jog(SPINDLEAXIS,speed * FACTOR * LastState);

sigh....
so i just tried some other C code examples that did the same double push thing
i re-load my own ones i posted above and now it works perfect
this is what blows my mind. :?

i am about to get a go pro camera and film what happens

ok, i got another used AMC drive ( 250$ ebay ) and the Z axis works as it should again!
everything works.
stoked
