Averaged Layer Heights Mis-represented
Closed, ResolvedPublic


The quality display section is not showing the properly averaged layer heights on dual extruder machines.

Steps to repoduce:
1.) Load TAZ Pro Dual Extruder machine
2.) Change e1 to High Detail Polylite
3.) Change e2 to High Speed Polylite PLA
4.) In quality, the layer heights properly average to 0.25mm
5.) Check quality selection, and it is still showing 0.35mm

Desired results:
Quality section shows actually averaged layer heights between the two

I think I have different desired results then. I'd like each extruder to display their own separate layer height settings, not have both display an average.

@matth Can you highlight where you would like to see this? As far as i know, to see individual settings for each extruder you need to swap back and forth and there is no spot to see them at the same time.

The slicer will require each extruder to use the same height to prevent collisions with the printed part during movement, which is why it will average those between the two.

@karrad I'm seeing this in 3.6.7. See attached screenshot.

Okay, I get what you're saying. In that case there just needs to be some documentation to notify the user why they can't have both nozzles print at different layer heights.

Alternatively, in cura there could be 3 tabs: global, nozzle 1, nozzle 2. Things like layer height would be under global, while things like printing and standby temps would be listed under each nozzle tab. At the very least, there should be a distinction in between settings that affect both nozzles and individual ones.

Lastly, in 3.6.7, no matter what profile I pick it says it's 0.1mm. I couldn't replicate it in 3.6.6.

@TKostennov Can you give us an update on this display issue? It appears to be generating gcode properly for layer heights, just not displaying the correct average in the quality bar.

@karrad Fixed. Now layer height in quality bar calculates from extruders layer heights.

@alexei This one looks good on a fresh build this morning, looks to be in master already. Closing this one down

Do we know the commit that fixed this?

@TKostennov Can we set the float on this to 3 digits? At the moment it is showing a lot of digits:

We would like this to just go to 0.XXX when rounding.

@karrad Fixed, check it please.

This one looks good, thanks @TKostennov
