******* Path shaping test *****************
cd /home/zamofing_t/Documents/prj/SwissFEL/epics_ioc_modules/ESB_MX/cfg

./shapepath.py -v255
```


Testing ServoFrq.
-----------------
```
!common(PhaseFreq=20000,PhasePerServo=4) -> 25000points, 20um error  leads the trajectory in x
!common(PhaseFreq=20000,PhasePerServo=2) -> 25000points, 6.6um error
!common(PhaseFreq=20000,PhasePerServo=1) -> 25000points, 6.1um error ossilates in y, x is quite good

-> the servo loop has to be optimized!
```

Testing linear,pvt,spline moves
-------------------------------
```

Tested with shapepath.py: THE BEST TRAJECTORY RESULT IST WITH PVT MOTION

```


Optimize/Test Parameters with Parker Stage
------------------------------------------

load program prg/testPerfGrid.prg
b2r

cd ~/Documents/prj/SwissFEL/epics_ioc_modules/ESB_MX/src/usrServo
make #will install the user servo loop
watch P3000 (average following error)
tweak servo parameters ->!motor_servo(mot=3,ctrl='ServoCtrl',Kp=20,Kvfb=220,Ki=0.02,Kvff=240,Kaff=1500,MaxInt=1000)

Same for motor 2 -> watcp P2000
Increase load will need an increase of gains to compensate following error

Motor[2].Servo.Kp=20
Motor[2].Servo.Kvfb=1000
Motor[2].Servo.Ki=0.07
Motor[2].Servo.Kvff=1000
Motor[2].Servo.Kaff=4000


Motor[3].Servo.Kp=20
Motor[3].Servo.Kvfb=220

Start motion on external signal
-------------------------------
```
open plc 1
Coord[1].DesTimeBase=0       // freezes timebase at boot
while(1)
{
  if(PowerBrick[0].GpioData[0].0.1==1)
  {
     PowerBrick[0].GpioData[0].16.8=255
     Coord[1].DesTimeBase=Sys.ServoPeriod
  }
  else
  {
    PowerBrick[0].GpioData[0].16.8=7
     Coord[1].DesTimeBase=0
  }
}
close
enable plc 1
-> run motion program. press gpio 0 to run at 100%

```

29.9.17 Testing in MX-LAB
-------------------------
```
Start the powerbrick. ioc is started automatically
zamofing_t@ganymede:~$ ssh x06mx-cons-1

caget SAR-ESB_MX:MOTOR_AX
cd /net/slsfs-crtl/export/sf/common/config/qt/
startDM -macro 'P=SAR-ESB_MX' ESB_MX_exp
press homing button
-> all axes can be moved.

(on thierrys laptop only)
cd /home/zamofing_t/Documents/prj/SwissFEL/epics_ioc_modules/ESB_MX/python
./shapepath.py
will execute the custom motion. No problems with EPICS
