Problem- NO graph for motor tuning

[cjchands]

This has happened to me few times now..
I installed the new program.
I go to config -> tuning...and you can see trapezoid graph for tuning.

Few days later..
You can change values for step, velocity, etc...but there is NO GRAPH???

System initial testing look fine...few spike here and there..but looks good.

System seem to run, but anyone know why this happen?

I reinstall and seem to be same problem.

How fast is your PC? If I recall correctly, this is a symptom of an underpowered PC.

Beat me...
I tuned it on today. And the tuning motor curve came back.
Nothing new install...nothing deleted.

The only thing that I did change was the wiring from Breakout board (step/direction) to the Stepper Drive.
I got wrong wiring (instead of +5V, I connect the ground instead to the Pul + and Dir +).

Yet..I don't understand why would this related to GRAPH not show up on the screen.

Btw....I am using Pentium 4, 512MB...
