Alden,

Enabling Status Report fonctionality causes some difficulties in handling feedback messages from the controller because it is free running . I added ( not replaced ) a little code in _gc_printsate() function in gcode_parser.c as follows:

mp_get_runtime_position(vector);
double velocity = mp_get_runtime_velocity();
uint8_t distance_mode = 1;

if (gm.inches_mode == TRUE)
{
vector[X] = vector[X] / MM_PER_INCH;
vector[Y] = vector[Y] / MM_PER_INCH;
vector[Z] = vector[Z] / MM_PER_INCH;
velocity = velocity / MM_PER_INCH;
distance_mode = 0;
}

if ((block[1] == ‘s’)||(block[1] == ‘S’))
{

fprintf_P(stderr,PSTR(“{“));
fprintf_P(stderr,PSTR(“”ln”:%1.0f, “), mp_get_runtime_linenum());
fprintf_P(stderr,PSTR(“”xyz”:[%1.3f,%1.3f,%1.3f], “), vector[X], vector[Y], vector[Z]);

fprintf_P(stderr,PSTR(“”abc”:[%1.3f,%1.3f,%1.3f], “),vector[A], vector[B], vector[C]);

fprintf_P(stderr,PSTR(“”vel”:%5.2f, “), velocity);
fprintf_P(stderr,PSTR(“”mm”:%d}n”), distance_mode);
}

with this, I can get the status report asynchronously with the “?s” or “?S” command.
Is it possible to implemente this code in your firmware or some thing like this ?

Can you please give me your email address, I want send you a copy of my GUI just to give me your oppinion .
thanks.

Alden, Now I better understand when you say you are trying to make things as real as possible ! I’m really impressed and I appreciate how you do things.

I will temporarily use the “@” character to stop all axes movement, and to maintain the actual positions, I wrote a little code in the routine st_stop () in stepper.c as follows:

void st_stop()
{
cli(); // disable global interrupts

double s_vector[AXES];
mp_get_runtime_position(s_vector); // save current positions in s_vector

double s_vel= mp_get_runtime_velocity(); // save current velocity in s_vel

st_init(); // stepper subsystem
sw_init(); // limit & homing switches
mp_init(); // motion planning subsystem
sei(); // enable global interrupts
gc_init(); // gcode-parser

cm_set_feed_rate(s_vel);
cm_set_origin_offsets(cm_set_vector(s_vector[X],s_vector[Y],s_vector[Z],s_vector[A],s_vector[B],s_vector[C]));

}

This allowed me to continue the development of my little GUI until implementation of the famous Starting, Stopping and Feedhold commands.
Now I can control manually my cnc, set current position to 0 and independently set current Z position to 0.
