hi bang , the quality is not steady ,
at the bottom it is thin , after that is solid , and then it is thin again , more thin than the print is at the bottom .

this is only at a 25x25x25 mm range of space of the X280xY210xZ200 mm of the space capable of building :(

it also it does not tops the Z ...

i received the building platform did some Z axis adjustments ( unscrew the Z axis and left each axle nut with just one screw ) and did two prints . there are better than before , but i am not happy with the results .

i think there are more problems than i can solve and ...

thank you again bang for giving me guidance .

my first report of the 8 points i have to check .

1) they do not stay in the same position !

2) they are OK

3) they look ok , they move with the rod . i think that those are working and as springs , and i have tried to put the rod a bit higher with ...

here is a video with the Z axis making strange noises and stop moving ,always at the same two positions .

the command is from repetier .
this never happens when the Z axis are moving downwards .
even if this sound does not happen , the alignment of the two Z axis breaks ,and ...

thank you bang for pointing that to me :)

i think the temperatures in my case are ok, i dont have a specific thermometer to check them but they are close to what they should be according ambient temperatures . it is 17C in the room where the printer is and heating bed and printing head have the ...

hi bang ,
everything is pointing to that it is gonna work right , but not right and now

the basic problem is of course the aluminum building platform,which is bend toward the center (thats why the only print i did that looks that almost became something is at the edge of the platform ) . at ...

i took a video trying to specify the problem of Z axis to specific parts .

at the right Z axle , i put the lead rod and it slides down through Z axis nut like it should .the 4 screws at part No16 (Z axis nut) are tight .

an idea that just came to me but not for solution to my little problems , is that it might be better to have the parking position at the right side , to get the weight even, because when it is left and the X axis motor is also left , there is uneven weight at one side of the structure .
