The first Z is "Layer high" + "First layer high"

DBSDBS

After installing v.1.6.1 the G-code always start from Z 0.4 mm.

My setup:

Filament - 3 mm

Nozzle - 0.4 mm

Layer High - 0.3 mm

First layer high - 0.1 mm

First layer Extrusion width - 200%

NO support

this is an example of generated G-code:

It does not mater what kind of object is placed on the program.

If I add for example RAFT, the things goes worst:

In addition, THERE IS NO RAFT layers !!!!!

I've tested this on two different PC's with different configurations!

Whats wrong?

You could try calling curaengine from commandline and see if it works with this cura.ini. But apart from this I can not say what is going wrong for you. I used the bundled CuraEngine but I guess you did the same.

DBSDBS

I'm a little bit confused....

1. Thous settings are different from thous send by me...

2. I use the bundled CuraEngine and do not know how to use Cura from command line...

DBSDBS

May be something by me is wrong.

I've just installed Cura 15.04.5 and tried the same things

Every time when I try to change the first layer thickness, I receive "Layer high" + "First layer high"

So, the problem is ONLY with Cura!

With slic3r all is OK.

I've uninstalled all versions of Repetier Host and Cura from the PC, have cleaned the registry, BUT when I've installed the fresh downloaded Repetier Host 1.6.1, all preview settings were inside, and the results are the same.

With Slic3r I have no problems.

Any Idea what I have to clean to "forgot" all settings from preview installations?

Repetier

Regarding CuraEngine everything is stored in working directory/CuraEngine of repetier (File->Working directory) and the latest verison is cura.ini directly in working directory.

Have you tried different stl files? Maybe it is just a stl file cura engine has problems with for whatever reason.

DBSDBS

Yes, It does not mater what kind of file I try. Every time the results are the same. I've tried even with the part that occurs automatically with new installation.

DBSDBS

I've deleted cura.ini from working directory, and when I've started again the Repetier, cura settings are still there.

Repetier

cura.ini is only the result from last call. The CuraEngine subfolder in work dir contains settings.

Have you checked the log if you see any error messages from CuraEngine there?

DBSDBS

Even after fully deleting of any ".ini" files in working dir, uninstalling, restart and reinstalling, when I use cure, the problem exists. When I use Slic3r, always the initial Z is correct.

Repetier

Again, what does the log say when cura slices?

DBSDBS
