[Installing Z-Offset Plug-in without Internet connection]

Is there any way to install fieldOfview's Z-Offset plug-in on Cura 4.9.1 without an Internet connection? (Education environment)  On the Github repo it indicates "No releases published". 

I have installed it on a system that has an Internet connection.   Can I obtain a file copy from that system?

Any help appreciated.

Thanks.  I guessed that was the case.  The bold text was an accident.   Fast response appreciated.

 

[Using Z-offset from Marketplace in Cura for Ultimaker 2+]

Newbie here, trying to understand just how the z-offset (by ahoeben/afieldofview) works.  Please bear with me being long-winded.

 

Running Cura 4.6 with the z-offset plugin.

 

Suppose I level and physically set the bed to, say, 0.2 mm below the nozzle.

I print some PLA with z-offset = 0 in Cura UI.

Now I want to use PETG, so I use the plugin in Cura UI to set a z-offset of, say, +0.25 mm.

So now Cura is telling the printer that, physically, 0.45 mm below the nozzle is the Z=0 position.

I print a model.

If I run the same gcode again, does the printer know to set the bed 0.2 mm below the nozzle, before running the gcode to change the z-offset, to set the bed 0.45 mm below the nozzle again?

If so, the absolute altitude of the bed following calibration (the 0.2 mm value) must be stored somewhere and used to initialize the Z axis.  Is this done by the firmware before the gcode is run?

If not, how does the printer driver avoid stepping the bed lower each time the gcode is run?

 

Explanation appreciated.  This community is appreciated.
