SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
first time using kflop and kanalog, this is going to bring back to life a 1994 Morbidelli cnc router with an obsolet computer. for now lot of work coming up.

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
I have a question about the opto inputs on kanalog JP15 terminals. can i use this terminals for connecting my limit, home, estop switches? i know the bits 12 to 15 are designed for limits on kflop digital I/O window, or i have to use the JP12 terminals for home,limits,estop? i tried connecting a limit sw. to inputs 0 on JP15 negative to ground and positive to 5v+ with the switch Normally closed, i can see the check mark in kanalog I/O window turning on and off as a activate the switch, but it doesn't stop the running program, i am confusing with this, do i have to modify some of the c programs?

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
Any input can be configured as a limit. Those on KFLOP are only suggestions. See here.
Homing is handled by a C Program which can use any input. See here.
EStop can also be any input(s). It can be monitored in a C Program forever loop and then perform any necessary actions.

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
Hi Tom
i have the switch detected and working in the bit 1172, the LED and the check mark turns on and off when push the switch, now i am dealing with the c programs to make that switch to work as a Estop, i opened the ExternalButtons.c file, and i added #define ESTOPBIT 1172, i also noted that in the section //handle ESTOP in the line if (result ==0) i change to 1, it reverse the polarity of the swich N.O or N.C, that's ok until this point, the question is, when i run my G code in KmotionCNC, i press the switch to simulate an emergency stop, and it do not respond, now if i execute in C the program ExternalButtons.c with the save,compile arrows button then the Gcode first get in feed hold, and now if i use the phisical switch it does stop the program like it suppost to do, but my question is, how to make the switch call the Estop directly when the program is running, like an emergency, maybe i need to add some instruction in the InitKstep3axis.c file? that's what i am using to enable the software.
thanks

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
Correct. Add the ExternalButtons loop to the end of your INIT C Program so as soon as the system is initialized it executes the code forever.

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
I added the externalbutton loop at the end of the init program, but when i try to initialize the software it doesn't do anything, if i remove the externalbutton loop from the init file then it works, while it runnig i paste back the loop and compile it then it works ok, the switch activates feedhold, the problem is when reset the program with the stop button or start the software, i know i am doing something wrong, i pasted below how the init file looks like.
thanks

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
Hi NOELNOG,
You pasted the entire program at the end. Instead only paste the "for" loop. A C program starts at the main() function. You can only have one main function in a program.

Thanks Tom, it's running ok now.
how can i add messages in the program to pop up in the screen when determined switch is active?
