I can jog with the arrow keys & Joystick fine but when I run a program it acts like it steps at .180" at a time.
Also acts like the communication between the ModIO and Mach has some sort of 2 second time delay.
Press a button and wait for it to respond.

Anyone seen this before?

Not an expert but I see this when I change direction and the backlash is kicking in.

I never said I was changing direction. It looked like a series of incremental moves with a 100ms dwell. Did not make a difference in what axis.

I did find the problem  
And I hate 5 volts.  
Had a poor connection on a +volt terminal. It kept getting worse till it finally failed the E-stop signal.
Soldered her up and now better than ever.

Thinking it might have been a computer issue:
It gave me a chance to try out a new computer I am eventually going too.
running @ 75K, It can feed at 200+ inches per minute, Boy am I looking forward to that. Best I get now is ~120.

Still think we need a opto board that has 20+ I/O (spring loaded terminals) with 5 volts on one side and 24 volts on the other would be nice.
Cut down on my use of relays for my stack light too from the ModIO board signal. If anyone knows of one let me know if not I will make my own this winter.

Thanks for scratching your heads, hope this helps others.

You never said you wern't

I have now reach the level of my expertise

no, I'd say your stretching it.

Reminded me of; "There is no such thing as a stupid question.... but be ready for a smart ass answer"
 

Thanks anyways
