Mesa 7i76e pncconf open loop stepper leadshine

Hi,
Can someone please give me some more information about how to use linuxcnc with mesa 7i76e for leadhine stepper controllers. I generated the config with pncconf but there is no way to choose open or closed loop. So the tool generated closed loop i found on github this config.

github.com/medicusdkfz/LotteCNC

so i changed also like he dose back to open loop but is this correct`?

# ---closedloop stepper signals---

#net x-pos-cmd    <= joint.0.motor-pos-cmd
#net x-vel-cmd    <= joint.0.vel-cmd
#net x-output     => hm2_7i76e.0.stepgen.00.velocity-cmd
#net x-pos-fb     <= hm2_7i76e.0.stepgen.00.position-fb
#net x-pos-fb     => joint.0.motor-pos-fb
#net x-enable     <= joint.0.amp-enable-out
#net x-enable     => hm2_7i76e.0.stepgen.00.enable

# ---openloop stepper signals---

net x-pos-cmd    <= joint.0.motor-pos-cmd
net x-pos-cmd    => hm2_7i76e.0.stepgen.00.position-cmd
net x-pos-fb     <= hm2_7i76e.0.stepgen.00.position-fb
net x-pos-fb     => joint.0.motor-pos-fb
net x-enable     <= joint.0.amp-enable-out
net x-enable     => hm2_7i76e.0.stepgen.00.enable

But what about the PID why i need the PID? Do i need to change anything on the PID settings? 
Dose anyone can share a config for a open loop steper for mesa 7i76e

Here i will share my working config and i will commit my progress here if anyone needs this

Thanks alot
