SelectExtruder Plugin in Cura 2.5 Beta 2

[cadshef 0]

Is it possible to use SelectExtruder Plugin in Cura 2.5 Beta 2?

I tried to put the file SelectExtruder.py to the folder C :\Program Files\Cura\Plugins and to the folder

C :\Program Files\Cura\Plugins\PostProcessngPlugin\Scripts, but it does not give a result !

Please help me anybody - how is it correct to set and start Plugin, that Cura saw him?

If its a Cura 15.x version plugin, it would have to be rewritten in order to work in Cura 2.x

If its a Cura 2.x version plugin, it probably just needs to minor changes to make it compatible with Cura 2.5.

I also second this request :-)

Unfortunately it's an 15.x plugin...

On the short run you could just manually insert a T1 in the header of the gcode, but to make this plugin working again would be great...

@DaHai8, is there any chance that you could assist?

Sure, I'd be happy to. Looks like its on GitHub: https://raw.githubusercontent.com/Dim3nsioneer/Cura-Plugins/legacy/SelectExtruder.py

If that's not the right one, let me know.

I'll start hacking away at it...

Yes, that´s the correct one.

Awsome that you jump in :-)

Ok, here's the converted script. Tested on 2.5.0 Release. I generated some g-code with/without this post-processing-plugin and it appeared to make the correct changes for the extruder number. But I don't have a multi-extruder printer to test with - so Caveat Emptor

You can also download if from here: SelectExtruder.zip

DaHai8, thank you very much!

I will make attempt tomorrow, that turns out with the edited script. About results will write.

drayson, also thank you for a help!

What does the plugin do?

Is this still necessary for Cura 2.x?

DaHai8, you're THE man - as always :-) Thank you very much, I will give it a try tomorrow afternoon (when my wifey is outa home :-) )

@ Zerspaner_Gerd, unfortunately yes as there is no option in a dual setup to heat only the one required nozzle and not both. only workaround is to use a single setup for single prints and there is no nozzle selection possible... so thanks to DaHai8's magic there is again the possibility to select the nozzle on a single nozzle print without manual tweaking.
