Hi Tom,
No its not always three seconds, sometimes its .5 second sometimes its 10 secs.Its connected to winford breakout board from J6,MPG is connected to same BB and having no issues at all.
I've connected the 3.3v out from kanalog directly to switch then back to bit 35 . The system is grounded well.
Tryed kanalog input 142, But i get buffer starve in mach every time I depress the feed hold.
? where do i pin into the LED on kfop.

Regards
Goran

Hi Tom,

Could it be that the opto inputs need 5v to pull it.

Goran

Greetings,

I have a simple but frustrating problem. Any time I perform motion on KMotionCNC it will move on any axis with the on screen arrows. However as soon as I stop the motion the yellow feed hold button starts to blink. The only way to turn it off is to E-Stop and reinitiate.

I have unchecked all of the "Limit Switch Options" on the configuration screen for all of the axis. This doesnt seem to help at all. 

Is there anything else that I could be missing?

Thanks,

Scott

Hi Scott,

Are the any messages on the KMotion Console Screen?

Do you have Soft Limits Disabled by setting +/- Huge Values?

Could you post your Initialization C Program?

Regards

TK

Cool.  Thanks for posting back.

Figured it out.. Knew it would be simple, but still took a few hours. I had the positive and negative soft limits reversed on one of the axis. Just didnt notice the negative signs when I was looking through.
