@gr5 Well, my controller is a Bigtreetech SKR 1.4 (32 Bit, 120Mhz clockspeed), should be potent enough to drive the required speeds, It is not that I'm pushing my delta, for most delta printer enthusiasts I'm printing slow with it. I have tweaked the firmware to 8, 16, 32 and 64 Gcode lookaheads, change was none visible, only in corners it got a bit better. There are no small gaps that need to be filled. It's happening in the outer shell: There the printer stutters, due to the bowden more filament gets squished out and then the model looks not nice anymore when the printheads slows rapidly down and then accelerates back up. ^^ I'd happily try a beta/nightly build of Cura when there are some fixes applied. Honestly, it occurred only in the later versions of Cura, my most printing time I have spent pre 4.0 Release. Then even with the 8 Bit Ramps I could push 50mm/s without any hassle. ^^ 35mm/s is a waste of the fast delta. I mean I can live with some ringing and also light stringing, but not with heavy stuttering that ruins every model. Also, I like Prusa but I like Cura more, because it is more Intuitive and has way more settings to adjust than Prusa. Specially the Z-Seam adjustment in cura works well.

Hey gr5, thanks for replying. The accelerations of the delta are 1500-2000 I think, Jerk is 15. Buffer is set to 64, I looked it up really quick. I will look into the gcode on both files with the same object. 🙂 Well, my printer does stutter on every layer, the results aren't very nice and smooth. I used on Fusion 360 first the high, then the medium and then the low setting, only at the low setting the stuttering was reduced, but didn't go away. The circle is 2mm wall thickness and 100mm in Diameter. Also when I want to print a vase in Cura, the printer stutters at round objects, even at 35mm/s.

Hello Guys, I have Three Printers: A Ender 5 Plus, a Anycubic Kossel Linear Plus (Upgraded to 32bit) and an Renkforce RF100, and on all I encountered stuttering when I want to print round objects or some with a curve. I need to go as low as 35mm/s to keep it under control. Kossel (since Delta) runs on 32Bit with increased lookahead-Buffer, Ender 5 only 8 as well as the RF100 (but all of them have TMC2208 in them). I used a circle as test: Prusaslicer and all printers print fine and without any stuttering, I've Pushed the Delta to 70mm/s and it printed fine (only the hotend struggled a bit, but the whole thing runs only on 12V...). Also The 5 plus printed fine. Is there a solution? It is clearly slicer related, cause on Prusa everthing is fine and dandy, only with Cura it isn't nice anymore. Tweaked setting are: Model resolution, max. deviation, max. Resolution, none of which caused it to get better. With Prusa with the same model and as close as possible setting, everything easy. I like Prusa, but there are missing some options (coasting, Z-Wipe etc.) which have resulted in very nice and good looking prints. Also in the Kossel's Firmware I disabled S-Curve acceleration, but also helped nothing.
