after i followed every command sent by CW to board, i observed that CW sent G1 Z5, to lift, and after that G1 Z -4.5, to set the height for the new slice, the build platform came in the same position like it was sending G1 Z-5. after more tinkering and reuploaded the firmware 3 time with no changes made, it seems to work, for now... any idea?

You can change to absolute positioning by chaning the
G91 ;Relative Positioning
line to
G90 ;Absolute Positioning
in the Start g-code.
Not sure if that'll help you, though.
Did you home the z-axis before printing?
The gcode for homing would be G28 Z or press the home button in CW.
Other than that I'm not entirely sure what your problem could be, I never had a similar problem before.

;********** Lift Sequence ********
<DELAY> 1000
G1 Z($ZLiftDist * $ZDir) F$ZLiftRate
G1 Z(($LayerThickness-$ZLiftDist) * $ZDir) F$ZRetractRate
;<Delay> %d$BlankTime
;********** Lift Sequence **********
btw thanks for the help

Can you go the full 20cm manually (by pressing the Z axis controls in CW) ?

#define Z_MIN_POS 0
and the prints look like this if are tall then 10 mm
first print was meant to be a cylinder, but...

Sounds to me like your firmware is set to max z-height of 10mm, so it won't let you get beyond that. In Marlin that be the Z_MAX_POS setting in Configuration.h . Sounds like that is set to 10 for you.

Congratulations for the great job you are doing here.
so, my problem is that on every print after 10 mm the z axis stops to rize, the print wont get bigger than 10 mm. the z axis will still do all the movements necessary to print but will not get bigger than 10 mm. any suggestions?
the print goes flawless, for the tests that i did till now, until reaches ~10mm, after that it won't grow,
i use megatronics v3, a top down setup, benq mp610, and a trapezoidal screw with 3mm pitch. and i use CW_Main_1.0.0.54
i will came back with photos.
