2) Most VFDs let you set a ramp rate as a configuration parameter, so
you don't need either the lowpass or the limit block in HAL.

Being able to set the ramp for different operations would be nice, maybe
in g-code?

If you use a limit2 block, the speed ramp rate will be constant.
Yes, I am aware of this, it was pointed out to me after I

Is there a way to set an arbitrary HAL parameter from G-code? I guess
with macros you can do it.

an asymmetry there.

Looks like it would be good in a shop environment and it has a parallel port.

The value could come from a g-code and be passed to M1xx as a P or

Hi,
sub: how to generate a pulse at parellel port out put using HAL
We managed to configure parellel port as out put or input
using
HAL commands.But we couldnt write a high value or low value to particular
data pin of parallel port.We couldnt execute those commands in HAL
