ABS + NinaFlex FDv2 TAZ 6 profile is missing start(1)/end(1) gcode
Closed, ResolvedPublic


This was a weird one.

Missing start/end gcode for single extruder use.

This is where it gets weird IMHO.
FDv2 pre-retail, v2b connectors
Cura 19.12
Machine Selection: LulzBot TAZ 6 (FlexyDually v2)
Quickprint: ABS + NinjaFlex, Standard Print

Steps to reproduce:
Load single model.
Save gcode
View gcode in text editor.

No start or end gcode.

Cura 19.12 doesn't insert Start2 or End2 gcode unless you use the option "Dual Extrusion Merge".

Setup: same as above

Steps to reproduce:
Load model
Load second model
Select Dual Extrusion Merge

Cura uses Start2/End2 gcode

Cura only uses Start2/End2 gcode if "Dual Extrusion Merge" is selected.

This happens with the 910 + pva profile as well. While support extruder = 2 is selected, no nozzle probing occurs, since there's no start/end gcode telling it to do so.

A user may attempt to print with only one material, with a dual extruder, using one of the dual extruder profiles.

Can we include the start2/end2 gcode probing behavior in start(1)/end(1) gcode as a fail safe?

kk awesome, we'll definitely want to test this one heavily, the way it selects which start/end gcode modifier doesn't make a whole lot of sense to me
