  1. You are going to have to use infill. Bridging isn't meant to be a replacement for infil.
  2. Any chance of a configurable volumetric speed limit? Your hotend has a melt rate limit, it can only push so much plastic reliably. For example, 10mm/s^3. Would it be possible to have a configurable value that would allow you to limit/warn when your speed and layer height/extrusion width combination exceeds the configured value. Slic3r does have this option, though it doesn't really warn or tell you when it's in effect. I would think this would be useful for variable layer height printing as it could scale the print speed on the taller layers to remain withi
  3. I was able to retest the original model at 0.15 layer height I posted about earlier using your build with bridging over infill. The results were very good. I still have to tweak the flow rate a bit, but it's going to make bridging when using low layer heights much more reliable. Bottom section is the bridging layer, and to the left side is one solid layer on top of the bridging layer. Another layer And that's after 3 layers of 0.15 on top of the bridging layer. The final top surface was perfect after two more top layers.
  4. Ha ha, Sorry about that. I've been meaning to test your builds for quite some time. Perfect. That clears that up. That would be nice. That makes sense. I installed your build on my windows machine that had no profiles yet so it was still using the defaults for skin removal. On my Mac with the official 4.0 build I had already reduced skin removal. Right, my point there though was could that be detected and then extend the top fill setting to replace the top/bottom fill to make one larger continuous section. Yes, I went
  5. Thanks, i'll look into that. @smartavionics Once I have cura-build setup, how do I build your version?
  6. @smartavionics So I've done some testing on your latest build with good results. I also have a few issues, questions, and requests. First, the bridging performance over infill is now very good. I still have some tuning to do, but first few prints were night and day compared to the official cura. First, here's the .3MF I've been testing with. Test print is an easter bunny chocolate egg dispenser. 0.6 nozzle, 0.3 layer height, 70mm/s ish. CFFFP_e_egg_dispenser_bunny.3mf Bridging over infill is working much better now. That's over
  7. Just doing some more back to back testing between your build and the officialt build and I think the GUI responsiveness is a bit better with yours when a sliced model is being previewed.
  8. Thanks, I'll try and do some tests tonight and let you know how it goes. If the first bridging layer over the infill is successful I think it should be fine. It has a better chance of working since it's already semi supported unlike true bridges.
  9. Sorry for the confusion. In a word, no. Performance in your build and the official 4.0 is the same. Is there anything else I can test or information I can provide? I would love to have the level of performance from the legacy view with the detail of the proper layer view.
  10. It gets very slow in the layer view. 4.0 is much faster using the UI, I'll give it that much. 3.6 was slow all over. Now the UI is mostly responsive even with a model loaded. But once it's sliced and you're previewing it in the layer view it starts to chug. The UI gets slow as well. Once you've changed a setting and the layer view disappears it's faster again. I made a quick screen recording to show it. https://www.dropbox.com/s/3f9z9uimjkzwikf/SlowCura.mp4?dl=0 It's definitely using the Nvidia GPU. Sadly Apple isn't allowing nvidia to release any web drivers for Mojave
  11. @ahoeben I tried the build. It works this time, however, performance is still awful. If I turn on legacy layer view it's super fast, but obviously limited.
  12. My mistake, I thought that was already part of the experimental settings. That would be a really great addition. I'm still surprised that's not something that happens with Cura by default. I would love to build an OSX release, but I have no idea how to get started with that. If you can point me in the right direction... I was able to test the Accel and Jerk for bridging settings and it appears to be working. Now If we can get bridging over infill implemented I'd say it's pretty much perfect. Thanks for all your hard work on these. Your branch fixes
  13. @smartavionics Just as a comparison, here's a picture taken at the same point during the same bridging section done with Slic3r PE. Same speed and layer height settings. Bridging layer at 35mm/s and 98% flow. Subsequent solid infill at 90mm/s
  14. @ahoeben I just tried your build on my 2013 MacBook Pro running Mojave and it says the app is damaged and can't be opened. You should move it to the trash.
