First time poster, I’ve checked looked around the forum and not seen this exact issue. I have a part with several T-Slots in them, trying to get the best slice settings for a good internal surface without much post-processing.
Below you’ll see two slices of the same part at the EXACT same settings, but with different results. The first slice applies a Bottom layer infill (purple) over the top of the T-slots, which will have some of that applied over unsupported areas, and i’m concerned about sagging… the slice shown second applies bridges (blue) over the T-Slot.
To get from the first slice to the second slice i have to do the following sequence.
- I have supports on, but touch plate only - Slice - T-Slots are not bridged.
- Turn off supports entirely and slice - t-slots are now bridged.
- Turn on supports, and also turn on “Don’t support bridges”, then slice. T-Slots are still bridged, but are unsupported in the middle.
- Turn off “Don’t support bridges” and then slice again. Finally, i have bridging on and the bridges are supported in the middle.
If i don’t do 3 additional slices in that order with those setting changes, it will always use bottom layer instead of bridging over those T-Slots.
In the end, the settings are exactly the same as when i started.
Does anyone know what’s going on with this? Should it be acting like this? Is this a bug? Should it be using bridging from the start on these overhangs?
