stepgen maxvel too big and SRO problem

  I have a problem with the stepgen: the max velocity is too high. Where and which value do I need to adjust? My steps with the Mesa 7i96 are 10,000 steps for the spindle.

The second problem concerns the MVO rotary encoder. The spindle and the normal feed work, but the rapid-feed encoder does not. Even when I swap the inputs for feed and spindle, it still doesn’t work. It seems to be an issue with the GUI/interface? Where can I start looking to solve this?

 

The "Maxvel is to high" error means that the stepgen cannot physically generate
the  requested step rate with the current steplength and stepspace parameters.

Options are to:

Lower the steps per turn on the spindle drive

Lower the spindle maximum RPM

Lower the values of the step length and step space parameters
(as long as they still meet the drives minimum width specifications)

The maximum RPM will be 60/(steps per turn(step_length+step_space))

So for example at 10000 steps per turn and 5000 ns (.000005 seconds) for step length
and step space, the maximum RPM would be 600...

You must degrease maxvel or you must degrease step timmings.

The second problem concerns the SRO rotary encoder. The spindle and the normal feed work, but the rapid-feed encoder does not. Even when I swap the inputs for feed and spindle, it still doesn’t work. It seems to be an issue with the GUI/interface? Where can I start looking to solve this?

We need more information. Specification encoder? Wiring encoder? What SRO mean?

The encoder works on the spindle and for normal feed rates. However, if I switch the input in the Mesa software to rapid feed rate overlay, the bar does not move with the same encoder as for normal feed rates and the same wiring.

I don't actually need the rapid overlay. If I could operate rapid and normal feed with the same encoder, that would also be OK.

The GUI's don't always "know" that you have changed an override.

Which GUI are you using? And how are you overriding (ie, which HAL pins are the counts going to?)
