Hi Mariano,

#include includes files not threads. Yes you can #include as many files as you want in a C Program. It isn't clear what you are attempting to do. #include simply replaces the #include with the text of the file. Its simpler to just put the code in place yourself. You might read this about how Threads work (which is unrelated to including files).

HI Tom, I have all axis going on a bench with my spare kflop/kanalog , and i want to implement the home routine
at the moment Im concentrating in the Z axis , and using jp15 in the kanalog , by hooking up a N.C. switch via a +5v supply
to the + termional of the jp15 IO 138.
I can see the tick mark in Kmotion digital IO screen on IO 138 , when I depress the switch,
When I start the home program it goes towards the top of z axis , but it does not read the limit switch when I depress it
I believe that this program does not look at the Kanalog interrupts , but im a very far from being a novice , let alone an expert on C
this is the program
can you please help?


#include "KMotionDef.h"
#include "SimpleHomeIndexFunction.c"
#define TMP 10
#include "KflopToKMotionCNCFunctions.c"
// home subroutine
main()
{
int result;


ch0->LimitSwitchOptions = 0x0;
ch0->SoftLimitPos = 1e30;
ch0->SoftLimitNeg = -1e30;
ch4->LimitSwitchOptions = 0x0;
ch4->SoftLimitPos = 1e30;
ch4->SoftLimitNeg = -1e30;
ch5->LimitSwitchOptions = 0x0;
ch5->SoftLimitPos = 1e30;
ch5->SoftLimitNeg = -1e30;

// HOME Z

result = SimpleHomeIndexFunction(0, // axis number to home
10000.0, // speed to move toward home
+1, // direction to move toward home (+1 or -1)
138, // limit bit number to watch for
0, // limit polarity to wait for (1 or 0)
100.0, // speed to move while searching for index
-1, // index bit number to watch for (use -1 for none)
1, // index polarity to wait for (1 or 0)
750000); // amount to move inside limits

if (result == 0)
{
printf("Home Z succeded\n");
}
else
{
printf("Home Z failed\n");
return;
}

// HOME X

result = SimpleHomeIndexFunction(4, // axis number to home
5000.0, // speed to move toward home
+1, // direction to move toward home (+1 or -1)
0, // limit bit number to watch for
1, // limit polarity to wait for (1 or 0)
100.0, // speed to move while searching for index
-1, // index bit number to watch for (use -1 for none)
1, // index polarity to wait for (1 or 0)
45000); // amount to move inside limits

if (result == 0)
{
printf("Home X succeded\n");
}
else
{
printf("Home X failed\n");
return;
}

// HOME Y

result = SimpleHomeIndexFunction(5, // axis number to home
10000.0, // speed to move toward home
-1, // direction to move toward home (+1 or -1)
0, // limit bit number to watch for
1, // limit polarity to wait for (1 or 0)
100.0, // speed to move while searching for index
-1, // index bit number to watch for (use -1 for none)
1, // index polarity to wait for (1 or 0)
43000); // amount to move inside limits

ch0->LimitSwitchOptions = 0x0;
ch0->SoftLimitPos = 46000;
ch0->SoftLimitNeg = -46000;
ch4->LimitSwitchOptions = 0x0;
ch4->SoftLimitPos = 60000;
ch4->SoftLimitNeg = -10000;
ch5->LimitSwitchOptions = 0x0;
ch5->SoftLimitPos = 18000;
ch5->SoftLimitNeg = -30000;
DoPC(PC_COMM_HALT); // stop KMotionCNC
if (result == 0)
{
printf("Home Y succeded\n");
}
else
{
printf("Home Y failed\n");
return;
}

}


regards
Mariano

Hi Mariano,

I don't see anything obviously wrong.

When the limit switch switch is "hit" does the Digital IO Screen show checked or unchecked?

Which direction is positive Z? Up? You might use the Console Screen to Jog slowly and observe the Axis Screen.

What is the resolution of your Z axis? How far is 750000 counts? Seems like a big number to move just slightly away from limit.

You might observe the Axis Screen when you command home.

You might add diagnostic printf statements to SimpleHomeIndexFunction.c so you know what it is doing.

Please post code with the Code Tag </> so it is easy to read.

Hi Tom;
thank you for your help, got the program doing what it supposed to do.
This program , knows were the limits are , and will throw a feed hold and wont allow to pass any limit, that has been set
This bring me to the new feature that I want to implement.
I want the controller to look ahead in the gcode program before executing and give me a error if the limits are going to be reach
Can it be done? if so can you help please? Wire Edm machines are very slow process machines , and the look ahead feature is a must in my opinion
Of course after the program is finished and working ok I will post the code here for everyone benefit.
Mariano

Hi Mariano,

Pushing the "Run" button will run a simulation and should flag any Soft Limit Errors.

Hi Tom;
one question on microstepping setting
Im having problems with my stepper motor not being as smooth as I would like with the 10 microstep setting in the driver
as I have no other available setting ..Can you please tell me if I can use the microstepping setting in kmotion, so I can combine both
,for example , 10 microsteps in the driver multiplied , by 10 microsteps in the Kmotion setting =100.
can it be done?
thank you

Hi Rasta,

No. If your Driver has a certain step size there is nothing the Controller can do to move less than 1 step.

"Microstepping" mode is for use with our SnapAmp Driver where it controls motor coil currents directly in a sinusoidal manner that achieves very high effective microstepping.
