Strange Z Axis actions

[m4rten86 0]

Hello everyone,

i hope anyone can help my with this strange error.

I tried to print a chainmail. After 3 layer it started to show this crazy behavior.

 

Dropbox-Link to G-Code

I took a look in the Gcode File and there are no such crazy Z Movements. For example in the Texteditor with the gcode opened, in row 150.000 the Z movement command is

...

;LAYER:3

G0 X33.585 Y33.165 Z1.2

...

then after 73.000 command-lines the next Z-Movent is comming:

...

;LAYER:4

G0 X33.318 Y33.884 Z1.5

...

so no rapid z moves should come from the gcode.

Here are my used components:

Slicer: Cura v2.7.0

3D-Printer: Ultimaker2

Firmware: Tinkergnome

Printdata is feed via Octoprint from Raspberry Pi 2

iam thankful for every reply
