Test 1
- Setup …
- Same filament selected for “Support base” and “Support interface”; and …
- Different patterns selected for “Base pattern” and “Interface pattern”; and …
- (optional) Different spacing selected for “Base pattern spacing” and “Top interface spacing”; and …
- 2 selected for “Top interface layers”; then …
- Events …
- Slice plate; then …
- Result …
- As expected, 2 top interface layers are created; verifiable by scrolling Layer Slider at right in Preview pane while visually counting layers attributed with the “Interface pattern”; and …
- (optionally) If different spacing was selected for “Base pattern spacing” and “Top interface spacing,” top 2 layers are also attributed with the “Top interface spacing.”
Test 2
- Setup …
- (setup same as Test 1); except …
- Different filaments selected for “Support base” and “Support interface”; then …
- Events …
- Slice plate; then …
- Result …
- Not as expected, 3 (not 2) top interface layers are created; verifiable by scrolling Layer Slider in Preview pane while visually counting layers attributed with the “Interface pattern”; and …
- (optionally) If different spacing was selected for “Base pattern spacing” and “Top interface spacing,” top 3 layers are attributed with the “Top interface spacing”; and …
- Notably, 1st (additional?) layer of the 3 top interface layers is “Support base” filament, not “Support interface” filament.
NOTE: I don’t know if the following might explain the above, but I can see value in having one additional top interface layer using the “Support” filament (not to be confused with the “Support interface” filament), purposed as support for the support interface filament layers, and using the same pattern and spacing, so as to completely support the actual support interface layers (and especially PVA). However, if this is the reasoning, it would be helpful if it could be a user-selectable setting (on/off), and also if the speed of the additional top interface layer could be independent of the “Support interface” speed; or at least apply the “Support” speed setting to the additional layer, and not use the “Support interface” speed for it (too slow).
