Print problem

Postby Spooku » Sun Mar 08, 2015 8:21 am

Hi guys,

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.

What firmware are you using?

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.

so... i checked and is like this:
#define Z_MAX_POS 200
#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...

Did you check that the Configure > Configure Machine > Build Size > Z Setting is correct in CW?

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

from control cw z axis goes full 200mm. i change it to 400, and stil its limited to 10mm.
how can i change from CW relative positioning to absolute:

;********** 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

That the z axis goes the full way when manually controlling it indicates that there doesn't seem to be a firmware problem (since the firmware will keep you from going over the limits otherwise). Is the distance travelled accurate as well? As in, if you move it 10mm, does it actually move 10mm?

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.

Update:

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?
