Good Evening Folks Made a few of those cubes with different settings and learned lots in the process. When I got to just a plain Cura PLA profile the corners seemed to square up with a 200C nozzle temp, so I decided to drop the temp from 210C to 190C, this helped a lot. Also whist testing the acc and jerk it seemed that faster for this filament was better so the final cube is also 1000 and 10. Thank you for all the discussion we have had, I really leaned lots about the printer and it's workings. I hope others watching the chat also learned from all your advice Cheers Warren

This is what I mean by inside and outside, the outside edges were left square to press up against the next bracket...

Yes the inside verticals are definitely fileted, but the joke is they look just like the outside ones that will push up against the next model, that are supposed to be square. I am keen to print that cube for you, just in the middle of a big print then I will do it next.

I just went back into Fusion now, seems that none of those edges have been rounded over, only the inside verticals, as the outside ones connect to the next bracket.

Yes the back corners a also the same 'perfect' bulge. Cool, let me set the Mesh Fixes to 0.01, and sadly yes, I have been doing everything from Cura on the PC via USB, I happy to try the card thing, just found it comfortable to click,click,click and the printer ran. Warren

Wow that is all good advice, thank you. I am definitely going to try those acceleration and jerk settings to see where I can go. All said and done this is a great learning curve as I develop my skills in this art. WRT the printer settings on the profile, I chose Ender 3 v2 when I started printing with this machine and have not changed it since, (asper the pic), so I have no idea where the Ultimaker S7 profile would have come from. The only thing I have done differently was to download that new Cura Beta, but other than that Ender3v2 all the way. Warren

Hi Guys, It is an Ender 3v2. I used the bowden extruder for that blue example and then added a Creality E.Fit Extruder 2 days ago. I am using that .3mf file at the moment, printing 40 of those parts and they all have that consistent bulge on all the vertical corners. Actually so consistent that I thought it may have been a setting I clicked in Cura to make it happen. Especially after the different materials did the exact same thing. (PLA, PLA CF, PLA+ and PETG) WRT the E Steps of the extruder, whilst changing the extruder I was then directed to adjust the e-steps to 405. Is there perhaps an extrusion setting I can change in Cura that I can adjust to mitigate this artifact, possibly do that Jerk and Acceleration thing gr5 was talking about? Kind regards Warren

I have just changed to a direct drive extruder last night, (the pic is from the old one), so i don't think over extrusion, but I am happy to try anything you suggest. Exactly same thing is happening with new extruder and different filament PLA Carbon fiber, original blue pic was PLA+ CE3V2NEO_F Clamk Rack v13 Center.3mf

Good Afternoon I use Cura as a slicer and so far I have had great success, loving it. I have though seen all my vertical corners are bulging and was wondering if there is a setting I have activated to allow this to happen? There is a pic I have uploaded showing one of these corners, but please be aware all my vertical corners look like this. Phatwarren
