I print 3DO ASA at 250/115,any reason you print it at 275? Do you run 0.4mm nozzle? Bridge flow % Chamber temp

Helge Keck•2y ago

bridging speed 25mm/s

conscious-sapphireOP•2y ago

What speed with that temp? No particular reason. Current default speed is 200mm/s 0.4 nozzle yeah, 100% bridge flow, chamber temp I can't say exactly as I don't have sensors yet -- approximately 30 degrees? Cool, will try it lower -- currently at 60mm/s Nozzle is tungsten carbide

Thanks will keep experimenting. Think I need to finish designing the mount for my ptc heater and fit some sensors too. 😅 It never ends. I do have RGB via WLED for different stages of print now though so all the quality issues might fix themselves? 🤷‍♂️

Did it not work out for you?

conscious-sapphireOP•2y ago

Sorry, been at work. Just come back to check your settings and play now 🙂 Wondering if I will struggle with 45% fan though as my chamber is not actively heated so it only gets warmed by the bed. Lets see how she goes 😄 Dropped all your settings in, running a bridging test now. Cut the print time in half too.. this will be interesting. Ok so here we go!

You forgot to connect 1 end kekw

conscious-sapphireOP•2y ago

Bridging. Not such a great success but walls pretty good still so I’m keen to make this work at these speeds. 😅 Not sure what to try though as I suck hard at tuning.

stormy-gold•2y ago

Not sure why its missing to connect tho,maybe overlap of some sort.

conscious-sapphireOP•2y ago

To be fair that weird loops situation seems to happen no matter what so far I tried 25mm/s as well and got the same issue

conscious-sapphireOP•2y ago

Top = squeegie settings. Bottom = my old settings with bridging at 25mm/s

conscious-sapphireOP•2y ago

Left squeegie, right original. Walls actually look slightly better on your settings squeegie. And printed in not far off a third of the time — 18 mins. Bridging is a bit better on original, but it took 46 mins!
