tune stepper function

What stepgen number are you using?
I may be jumping to conclusions but i seem to see a difference depending on which stepgen i use. stepgen 0 seems to only respond when the numbers go really low and the max velocity will affect acceleration.

I used stepgen 3 also and it seemed to respond properly.
I'd need to test more to confirm/draw conclusions.

Also, can you describe the problem with halscope?
it's a 1000 times better then looking at halmeter.

for reference I'm using a 7i92 and 7i76 card probably standard 7i76 firmware.

Hi Chris,
.

What stepgen number are you using?

I have a firmware with 10 stepgen modules and I plan to use all of them. That means, any number from 0 to 9
.

Also, can you describe the problem with halscope?

Hm, I expected to see anything right of the box, but it shows nothing.
... and from combox at the bottom I can't select anything (combobox is empty). So I don't know, how to use that window.

I use the 5i24 with the firmware I sent you the mesa output from.

What stepgen number are you using?

I meant what stepgen were you using when you saw the failure to increase velocity.
In my test I'm seeing different behavior with different numbered stepgens.
for me - stepgen 0 showed bad behavior stepgen 3 did not. -suggesting that possibly the firmware/driver for stepgens is buggy.
It would be helpful if you could confirm this on your side.

halscope:
There is no combo box in at the bottom of halscope - there is a button for selecting pins.
but you may need to select a channel number (button) first.

on the current slot used I have stepgen 6-9 and I used 7 for rotary axis and 8 for linear axis.
So 7 showed the weird acceleration.

I'll check that later. Its to early to do hardware tests

I was able to bring halscope into play
This is what I was talking about:

This speedcurve is right for stepper tuning. But it would be helpful, to get some recomendations about what to do or a rating about current settings.

This way I see the curve, I know, it should be different, but I don't know what to do or what parameters to change ...

Whats your servo period set to?
