Ender 3 V3 : Some improvements for supports and machines limits #4527
Conversation
Why support_interface_top_layers has been set to 4? I'm not sure about this. |
It depends on the layer height, for thin layers, interfaces can sag and give bad results, hence the increased number of layers :-) |
I see. |
It's Creality Print values :-) |
Yes, but you know as well as I do that some settings in Creality Print don't make sense. Okay, one last thing for the V3 KE is the Jerk settings. |
Yes I know but I didn't check every settings one by one so good find ;-) |
20mm/s??? |
I'm currently testing the new settings. The z-hop of 0.2 has a bit of webbings on eSun PLA+, but my filament is a bit wet. |
I'm still testing. Sorry for the late update. My print is still running, I'll do another with these settings soon: The z-hop's new value of 0.16 seems to be fine for me. |

So I finished my tests, please change the jerk settings to these:
default: 9
outer wall: 8
inner wall: 8
infill: 9
top surface: 8
first layer: 8
Travel: 9
Generally, for travels, we seek the highest possible speed...

When I set it to 10mm/s it felt wrong. |
I would reduce SQV for outer wall but increase it for infill (quality loss for infill is not important), so I would say : default: 10 What do you think ? |
I'm sorry but there is a nasty vibration with these settings. |
Vibrations don't necessarily mean bad :-) |
No, I find it quite logical. You see, even with liner rails the bambu lab a1 has a limit of 9mm/s. |
I don't think it's possible without having a warning from Orca :-) |
By the way, the V3 SE has the same frame and the same motors. |
Yes it has, "Jerk" setting for Klipper is used to set Square Corner Velocity with Orca. https://www.reddit.com/r/klippers/comments/vse7ir/so_what_exactly_is_square_corner_velocity_and_how/ I don't remember if Creality has set that setting in the printer.cfg |
I opened my printer.cfg, this is what I found:
I don't think the firmware uses this? |
Ok, they didn't change the default value. default: 9 |
No, let me test this a bit more. |
So, I'm printing a cog, but without filament. That's my test bed. |
What kind of problems do you see ? |
When it finishes the first layer, during inner wall printing if I don't limit the jerk to 7mm/s, it will cause the bed to vibrate. |
Let's do this, we will set a hard limit to all jerk settings to 7mm/s and speed up the Outer Wall a bit. |
It sounds good to me ! So default: 7 ? |
Yes, that's fine. |
It should be safe :-) |

Looks good to me. There is a slight vibration on infill but that's fine.
Ok! Thanks for your help, we can consider this ready to merge ;-) |
@Orel-A suggested in #4225 some improvements for Ender 3 V3 KE and SE
I don't have those machines anymore but I can trust him so I changed some parameters.
Thanks !
