quik Questions ,, PLEASE )

Hi guys ,, i just finsh my 3d printer
menel ... and i start printing but when it finsh the 1st layer
z axis does not move up ،،Although the axis move normally up and down before start
printing ,, in other hand the speed of printing is so slow
compare with that videos i see it in youtube


can any help me , please

What slicer are you using?
Speed settings are done in the slicer. I'm one of many who have different speed profiles.
Also, are you entirely sure it isn't moving? When it does move it hardly moves because layers are thin. Pictures of prints with the not-moving Z axis?

I notice it does not move (z axis) it print 2nd layer over 1st layer without any space , also the shape deform and begin print another form


I use Slic3r website is version 1.0.0


BTY
After i upload firmware to melzi
I did not change the z offset, and z hight
If any one can explan it in details please

When you say move correctly in Pronterface that means that the y+ moves bed to the front x+ moves extruder to the right and z+ moves extruder up. That's if you have a mendel with moving bed a lot of people get confused with the y-axis direction because the bed is moving not the extruder if you look at the control panel in pronterface that's why people get confused

There are two settings for layer height in slic3r. One for the first layer hight, and a second for all the rest.

If you are getting no z movement after just the first layer, but are for the rest, maybe just the first layer height set very small. If you post the top of your gcode file here we can help troubleshoot it.
