Linistepper's "enable" specific configuration

Hi,

is it possible, to set up specific "enable" for use with linistepper, I mean logic power regulation.

enable = 1 (5V) - high power
enable = 0 (0V) - low power "hold" mode

I've tried amplifier enable for x,y and z

net xenable => parport.0.pin-1-out
net xenable axis.0.amp-enable-out => stepgen.0.enable
net yenable => parport.0.pin-8-out
net yenable axis.1.amp-enable-out => stepgen.1.enable
net zenable => parport.0.pin-9-out
net zenable axis.2.amp-enable-out => stepgen.2.enable

It works, but enable is TRUE, all the time, machine is powered on (F2).

Is there any way, to make it work for linistepper's "enable" - enable should be set to FALSE every time where there's no movement for each axis separately:

for example:
Z moves - zenable = 1
X stopped - xenable = 0
Y stopped - yenable = 0

?

It's possible with the spindle but not with individual axis AFAIK.

Hello,

You might want to look in hal for the pins that return the axis velocity to determine if they are moving. I think it is something like axis.2.joint-vel-cmd.
Try watching them first in hal to see if they give the results you are looking for. Also remember to add your variables to a thread so that they are updated.
