Dual Extruder v3 prime tower off printer bed when extruder 2 is selected
Open, HighPublic


While smoke testing 3.6.7 on Windows 10 connected to Taz 6 with Dual v3 extruder.
Any time I highlight an object and select "Extruder 2" CuraLE is failing to slice because prime tower is off the print area.

Verified that this is also happening in Windows 7 and I tested it with all dual extruder settings and this is only happening with Dual Extruder v3. I tested with Dual v.2, Flexy-Dually and Taz Pro and this was not an issue.

@Yahuba , Can you click on the "custom" selection instead of "recommended" and post what it says under the setting subheading "Dual Extrusion"? I would like to see if, in windows, it is pulling out of date info for the "recommended" settings. If you select the same profile quality in "custom" but it moves your tower position, then it is pulling bad info.

I tried to recreate it here but realized that our "recommended" settings don't actually include a prime tower being set to default, did you change settings and then go back to the "recommend" option or was this straight from start up?

SCRATCH THAT! I had the wrong material selected. it looks like I CAN recreate this. Im not sure what happening here but I will check out the settings and get them updated if needed.

Looks like settings need an update, not sure if this is something we missed a while back or something we accidentally updated inaccurately.
@karrad can we do a mass update to the Dual V3 settings for all materials?


Circular Prime Tower = YES
Prime Tower Size = 15mm
Prime Tower Minimum Volume = 10mm3
Prime Tower X location = 255
Prime Tower Y Location = 240
Prime Tower Flow = 105%
Wipe Inactive Nozzle... = YES

Re-tested this on the 3.6.8 build and still same issue but slightly different:
This time, you can load two objects and select extruder 2 which loads the prime tower in the display within the print range. However, if you change the quality of the print from its default value, it moves the prime tower out of the print area again and fails to slice.

Just a quick update: failed to say in my previous comment, I ran into the issue in both Win 7 and Win 10. The scenario described in my last post was in Windows 7.
When I replicated this in Windows 10, it was as first described where just selecting Extruder 2 creates the prime tower fail error.

Prime tower location is varying depending on model, so I'm not sure this should be set in profile. If we want to change location for all profiles for one printer, best way to do it is override it in printer settings file.

@karrad , @anolen : What is the status of this? Can it be closed as resolved?
