Andrew Ellis' print tuning guide (from which some of Orca's calibrations were derived) has a TON of detail about almost every aspect of all these tests and more He definitely has some opinions about calibration order and if you're into the down right esoteric aspects of everything its definitely worth a read through.
On Klipper you could use the tuning_tower command to tune your retraction speed. I find the tuning_tower command a pretty powerful and flexible tool for experimenting with what if scenarios on a wide number of printing parameters. Perhaps you should do a video on that?
Great video. Do you think you can make a video about the new contact functionality of the beacon probe. I know you have reviewed the beacon probe before. They just added a new contact function to it with a firmware update. I would love to hear what you think about it. Cheers, Heiko
not 10 mins before this video came out i started the process of re-calibrating my workhorse printer that i have made some changes to. Great timing lol.
I generally start with a temperature tower and then do a Flow multiplier test and then a a Max flow rate and then come back to PA. I've never been sure whether I want to do PA before the flow multiplier as it can help get more consistent lines when you're trying to figure out which tab has the best flow but I generally do it in the order I said.
I really like the lines pressure advance test since it significantly easier to tell what's going on, though I wish they would change the order it doesn't to do the big flat section first, that way you can ensure your bed offset is correct before it tries to do all the lines and inevitably have to do the print twice after finding out the offset was wrong once it gets to that section..
I do two different flow calibration prints one using the standard chiplet style to dial in top surface quality and then a 15x15mm cylinder with 4 walls only. It helps to get a perfect layer consistency when examining prints under harsh lighting. Definitely overkill.
I thought eSteps was fixed bssed on your extruder, assuming you have a quality extruder which I assume most are now days. I always struggle to determine which one of the flow values is the best one to pick.
Not a bad idea for easily removable nozzles on hotend like the Revo. IIRC Andrew Ellis noted that through a lot of his experimentation he doesn't think it's necessary. Setting the feed rate adequately slow and temp high enough can just about remove the concern of nozzle pressure being a restriction. I haven't done as much experimentation but personally the order of magnitude in the difference between hot and cold values wasn't big enough to be a concern for me Overall filament path (length and inner diameter of reverse Bowden tube), going from standard V0 to URBi for instance had a bigger impact on rotation distance then doing the test hot/cold.
Quick question for everyone. On pressure advance. Would you change it in your Klipper settings? Or just make profiles for each filament and leave it off on Klipper. Sorry for the dumb question
@@rayrod9010 thank you for the information. Should I set it to zero so it's able to be used or completely disable it with a # and orca slicer will take care of the rest?
@davidboop3550 yes, leave it on Zero in klipper When calibrating it should be also in zero in Orca everytime that you perform a PA calibration, then you set the value in Orca according to your result and save that value in that specific filament profile
@@rayrod9010 I will change that right now. I'm about to start a print and I'll go through a couple calibrations. Thank you very much for your time, I appreciate a lot. I hope you have a fantastic weekend
The Max flow is deceiving, 'cause I had this pet G that said I could do 20, and I wasted so much filament trying to figure the rest out when Max flow rate was wrong to begin with it was 7
@NoMercyFtw your English is so terrible that I have no idea what your talking about. Your struggling to explain your situation which doesn't make your point of "max flow is deceiving 'cause" any better as your illiteracy is keeping you from conveying your own idea. I think your just lost bud
The pressure advance calibration is 100% insensitive to flow, since a flow which is off by few % will only result in few % wider lines (in pattern and line mode) or tower (in tower mode), which will not impact the final value. So PA should come first. Advantage: since PA is now tuned, the flow calibration samples will have a much larger artifact-free central surface and identifying the correct flow will be way easier. With wrong or disabled PA the usable surface for the nails to check smoothness shrinks. PA Flow And typically that's it, since retraction is usually identical for all filaments except petg and tpu, which already have different retractio settings in the slicer. Also, retraction has a wider acceptable range so a specific tuning makes less sense. Rather do califlower for dimensional accuracy instead.of wasting time on rotation distance and retraction... It's more useful
Wow someone still recommends to change the rotation distance, which is filament-dependent and which should not be done, since the flow calibration ALREADY includes it implicitly. Also, as stated explicitly in Klipper documentation.
It’s always a good idea to make sure your within range. Adjusting flow on a filament basis is separate from making sure your rotation distance is set correct. It’s something you need to do once especially if you’re having big extrusion issues.
@ModBotArmy I understand but if the rotation distance is set to the physical amount and more than few percent is needed (which could be taken into account during flow calibration), then some hardware issue is present and touching the rotation distance is just hiding the problem. Not to mention, as engineer, that measuring the rotation distance is much less accurate than testing flow with the flow calibration routine so you end up needing the flow calibration anyway to compensate for a tedious, inaccurate and almost always unnecessary tuning.

Totally agree! Need to add a retraction speed test option.
I after 3 years with my printer still has a original hot end. Soon to have a direct drive. I will pay more attention soon also. Thank You ModBot

Try using the filagrip for estep calibration.
How about tuning fan speed and minimum layer time?
I thought eSteps was fixed bssed on your extruder, assuming you have a quality extruder which I assume most are now days.
I always struggle to determine which one of the flow values is the best one to pick.
With a Klipper printer do you need to worry about retraction extra prime amount if you have pressure advance tuned?
Noted! Thanks!!
About rotation distance for extruder - better test it without nozzle

On each filament... do not touch on Klipper setting

The Max flow is deceiving, 'cause I had this pet G that said I could do 20, and I wasted so much filament trying to figure the rest out when Max flow rate was wrong to begin with it was 7
No it's not 😂
@CrackedGh0st then why was the max flow rate reading as 20, The whole thing was perfect flawless
