Cura 2.3 and Z hop only on skirt - Normal Quality Profile

Recommended Posts


I have just updated to Cura 2.3

I always use Z hop as many of my parts have a flat top surface and Z hop avoids any marking of the surface.

I have just run the first job and got a surface mark. I examined the file and the Z hop is active on the skirt only. Any idea why this is? I see that Z hop works with Retraction which is enabled. What causes retraction? Have I missed a setting in the profile?

Many thanks.

That helps but there is still no Z hop in many layers.

You can check this by opening file and searching for Z.

Example from beginning of file:-

G0 X64.289 Y86.981


G1 Z1.27 ; Z 1 mm hop

G0 F2880 X64.318 Y136.09 Z1.27

G1 Z.27


Example from last layer in file:-

G0 F7200 X68.805 Y86.129

G1 F1332 X69.391 Y86.716 E11681.00058

G0 X69.452 Y86.777



G0 F7200 X69.353 Y86.875 Z3.97 ; only reference to Z in the layer


G1 F2400 X69.357 Y87.188 E11681.01154

I suspect this is because retract controls Z hop and presumably there is no retract.

Can you force retract to prove this?

I am not sure because I cannot see retract distance.

(This setting has been hidden by the values of gcode flavour, Enable Retraction. Change the values of those settings to make this setting visible) I do not understand what that means.

If I could set retract to say 1mm I could easily see that in the file.

What controls retract?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
