The printer config is setting the maximum values for the hardware. They can be set to what the hardware can do without skipping steps (and keeping 10% safety margin from where that would happen). There are various videos on UA-cam on how to find that point, but actually measuring that will be uncomfortable for your hardware and your nerves, so just using a reasonable max. value is often the best choice. The slicer can then set accelleration and speed within the range the printer / Klipper allows. Klipper will simply use the lower of its max. limit and the value set by the slicer. The slicer can of course dynamically change the speed and accelleration depending on the type of line it's laying down, whereas the max. limits in Klipper are pretty static. And for Marlin, basically the same holds, except that the max. values are either hardcoded in the firmware or stored in the NVRAM/flash by Marlin instead of a config file.
I was really hoping this was a guide on adaptive pressure advance. guess I keep waiting. only you have even addressed it exists in people I follow at this point.
@@minimal3dp You mentioned it in the 2.2.0 beta video but said you were going to cover configuring it later after the full release was out, that's what I was hoping this was but I can wait.
Thanks for the video. I'm a little confused on what the speeds & accelerations should be. You're mentioning how values in printer.cfg (which I currently can't find?) and the various Orca profiles can provide info that is not necessarily consistent. I'm running a FlashForge 5M Pro and using the Orca profile for that machine. I haven't modified anything. So would the provided speeds & accelerations be correct or should I be looking to make changes? If I should be making changes, what do I use to determine what the values should be set to? Also should you just do a full calibration for each new filament type that you run? There just seems to be so many things that can change from filament to filament (and the various calibration options Orca provides) that I think it makes sense to just test each new one you try. At least my goal is to try to determine a standard set of filament that I'll be using and I want to dial that in the best I can so I can get the best prints possible. Does that make sense or am I missing something? When I try to do the PA calibration, it displays the dialog asking me for my choices and I select PA Pattern and select OK. But it then appears to do nothing. I'm left with the plate with nothing on it and the Slice Plate isn't available (grayed out). What am I doing wrong? Appreciate any help. Thanks.
thanks for revisiting this topic. I tried as suggested and it's working as intended. However, I've just noticed today that if I have the "enable adaptive pressure advance (beta)" ticked within the filament setting, in the stl gcode, I saw 2 lines of set pressure advance. The first one is the setting PA according to the figure I wanted it to be based on PA calibration, then another line after ;AFTER_LAYER_CHANGE to 0. Not sure if anyone is also having similar issue or is it just my ORCA. if anyone can please confirm then that'd be muchly appreciated.
I see that i can 'disble' accel on the profile by putting zero and then uncheck to emit limits in the motion ability tab.. would that help to just let klipper handle that ?
This is a Klipper feature (the config). Are you using Marlin or Klipper? If it is marlin, let me know what printer you are using and I will try to post the steps.
@@minimal3dp I'm having trouble finding printer.cfg too. I'm running MacOS and am using a FlashForge 5M Pro which I believe is running Klipper. Where is this file located? Thanks.
Feedback: the voice sound of the Intro is got better, as in the past. In between the video its some irritating echo on the voice. Thank you for improving the quality, step by step.

I have another video that does a more in-depth cover on it. What would you like me to go over?
@@minimal3dp You mentioned it in the 2.2.0 beta video but said you were going to cover configuring it later after the full release was out, that's what I was hoping this was but I can wait.
I will work on it this week. I am a little behind with work.
@@minimal3dp take your time, and thanks

Have you gotten it figured out?

I see that i can 'disble' accel on the profile by putting zero and then uncheck to emit limits in the motion ability tab.. would that help to just let klipper handle that ?
I would try both ways and check time and quality.
Where can I find my printer config file? I'm fairly new to 3D printing but finally getting around to dialing in my 3D printer.
For klipper users, leftside menu, machine, folder(config).. the file its called config.cfg

I see the line width setting you are using is 0.5. Are you using a 0.5mm nozzle on the ender 3 s1?
No. I am using a .4 nozzle.
@@minimal3dp line width is set at 0.5 is the result better or how am I new to using orca
can you tell me why you chose 0.5 line width to get better or more precise print results?

I have been working on it. I truly suck at sound engineering
I appreciate the feedback
This is the hard part for me, what to do in Klipper, and what to do in Orca. I get the impression that a lot of this is being done twice or more.
I would set you max values in Klipper and then do any adjustments via orca. Orca overrides Klipper.
