+Up vision calibration
+---------------------
+part placed too far to the right?
+  increase X camera position
+part placed too far to the left?
+  decrease X camera position
+part placed too far to the back?
+  increase Y camera position
+part placed too far to the front?
+  decrease Y camera position
+
+part measurement width too high?
+  decrease "Distance/Pixel" X (first value)
+part measurement width too low?
+  increase "Distance/Pixel" X (first value)
+part measurement height too high?
+  decrease "Distance/Pixel" Y (second value)
+part measurement height too low?
+  increase "Distance/Pixel" Y (second value)
+
+Nozzle calibration
+------------------
+"NozzleDown"
+These values calibrate the 0mm depth, e.g. for the PCB this is the level of the PCB holder, the system will automatically add the PCB thickness
+
+"Down To PCB"
+1. manually move nozzle 1 over the PCB holder
+2. click "Nozzle Down"
+3. nozzle 1 should just touch the PCB holder
+4. adjust Z value of "Down To PCB"
+5. repeat from 2. until done, else click "Nozzle Up"
+
+"Down To Stack"
+1. manually move nozzle 1 over a pick position of a tape feeder stack (ideally no.1 of the left stack), no tape inserted
+2. click "Nozzle Down"
+3. nozzle 1 should just touch the metal surface of the pick position
+4. adjust Z value of "Down To Stack"
+5. repeat from 2. until done, else click "Nozzle Up"
+
+"Down To Front"
+1. manually move nozzle 1 over a pick position of the front IC stack, no part, just the bare stack where a part would sit
+2. click "Nozzle Down"
+3. nozzle 1 should just touch the metal surface of the pick position
+4. adjust Z value of "Down To Stack"
+5. repeat from 2. until done, else click "Nozzle Up"
+
+"Down To Discard"
+Well, this depends on your discard position and preference.
+
+"NozzleOffset(X,Y)"
+1. create a reference, ideally a thin lined cross (like a bullseye)
+2. "System Config" -> "Nozzle" -> "Measure"
+3. aim center of cross with down vision
+4. click "Reference" "SetXY"
+5. move nozzle 1 exactly to the center of the cross, lowering the nozzle onto the cross surface
+6. click "Nozzle alignment reference point" "Nozzle1:" "SetXY"
+7. move nozzle 2 exactly to the center of the cross, lowering the nozzle onto the cross surface
+8. click "Nozzle alignment reference point" "Nozzle2:" "SetXY"
+9. click "Save"
+
+Prick calibration
+-----------------
+1. choose vision mode
+2. down vision aim part at pick position, click "Set XY"
+this uses always the same button:
+3. click "Prick MoveTo"
+4. click "Prick Comp" - this will move the tape one component
+5. click "Nozzle MoveTo" - this will move nozzle 1 down to the component,
+   nozzle should sit on center of component, if not:
+  a) too far left: decrease "PrickOffset" X
+  b) too far right: increase "PrickOffset" X
+  c) prick does not land in tape hole, too far to the back: decrease "PrickOffset" Y
+  c) prick does not land in tape hole, too far to the front: increase "PrickOffset" Y
+6. repeat from 3. until nozzle lands in center of part
