can i use linuxcnc without it's PID loop?

can i use linuxcnc as just a step generator ?
without it's PID loop.

Yes you can
install latest wheezy stay on 2.7.14

BUT it gives you more benefit if make the pidloop work
its only once you got the things sorted
BESt to use wizard for base config and copy your privete things over

i understand PID can do a great job, but i have a servo drive which does it good enough for my simple application (NO machining involved ).
can you please guide me through how to do it,
i have a pico systems Universal Stepper Controller (Via parallel port)

Looking at the docs - it seems the Pico card does not have a step generator that supports position mode with an internal PID.

So unless you switch to Mesa or parallel port hardware, you are stuck with PID.

I know with the Mesa card the PID setting is pretty standard to get good results with the standard servo period.
P = 1000 FF = 1

Maybe you are looking for a simple trejectory planner for your non machining application?

simple_tp is a single axis trajectory planner that takes a target position and gives a velocity signal

oprn a teminal and type 'man simple_tp'

Yes.
Linuxcnc has its pid loop just in case you need it for steppers.
