Yes, I am interested in the comparison between the auto speed and Elias' method. I just finished updating my limits using Elias' method and was concerned that it was going to damage something. Best way to explain it is that it is very violent. I am on a tuned and modified Ender 3 S1 Pro. Good video as always.
you attempted to set the top surface speed to 50,000 but you actually entered and saved 5,000... you did still increase that value from 3,000 but said 50,000 but you just missed a 0. keep these great videos coming.
@@minimal3dp no, its all good, I just thought it could help to crank a few more seconds off the print time. But might effect the top surface print quality.
I am curious if you adjusted your material flow rate as well? When you sliced your model did you preview the speeds to see what was theoretically reached during printing? I seem to hit my limit on my flow rate for my creality k1 way before I reach the speeds I could reach.
at 26 seconds in the text on the screen says COREXY - ONLY!!! So I am making an assumption that this isnt applicable to bedslingers, did I jump the gun with my assumption?
Funfact i had exactly the same values as you. If you run AUTO_SPEED_VALIDATE Accel=78350 Velocity=1339 you can see that this is beyond what the printer can really handle. i think you need to add a real range in the printer.cfg
@minimal3dp So I had the same results and can't believe it's not something in the process causing it. I wasn't seeing the movements I expected from test_speed and sure enough my macro was't correct. I changed that and got more reasonable results.
probably won't make much diff but you only put 5000 on your top layer. What I'm more interested in is, if you're able to delve further into IS topic. Specifically troubleshooting Y more than X as that could be caused by cables, PTFE, mechanical, frames, I realised that this can be a bottomless pit topic, but again I haven't found any youtuber have taken this topic to the T.
You choose the worst model to try and test speeds and acceleration. Your not going to get anywhere near those speeds on that tiny cube. That's why the time difference was so small between the 2... Also, those maximums your setting will far exceed what your hotend can even produce which again, is preventing you from reaching that kinda speed during printing.
@@minimal3dp With such small model minimum layer time (from cooling settings) will probably kick in. You will need big model or disable it (which on small model will probably mess it up a lot :) ) + probably max volumetric flow in filament settings..

I appreciate your kind words. I am going to try to post a comparison next week.
@@minimal3dp waiting for that video, thank you

I am sorry for the mistake, but I appreciate the kind words. My own fat fingers are my worst enemy.

I have not adjusted the flow rates yet. Although the accelerations and velocities are fast, my print speeds are still slower.
@@minimal3dp slice your cube with the new speed settings. Then look at the speeds, you may be flow limited if you aren't seeing the speeds.
So the only method we have for bedslingers is Elias' one and this isnt applicable for ender 3 users?
Why won't it work with Ender 3s?

Why Im getting diffeent number once is over 4000 and after 2 rounds Im doing again and then around 2100
How do you change the max missed value for sensorless?
AUTO_SPEED MAX_MISSED=10.0
Funfact i had exactly the same values as you.
If you run AUTO_SPEED_VALIDATE Accel=78350 Velocity=1339
you can see that this is beyond what the printer can really handle.

I will probably change the range. I will compare to Ellis’ method, and I think the VFA(?) test in orca slicer.
@@minimal3dp yeah but thats also another story

It’s Ellis, not Elias
Dang spell correction got me. Thanks for the heads up. I Wii fix it when I get home.
What print times?
15 minutes vs. 12 minutes. I need to increase the print speed to levrragethe faster acceleration.

Dang, I ment to do a top of 50000 and fat fingered it. I will look at the trouble shooting.
Weird. For me running the AUTO_SPEED macro tells me the machine is not homed, even tho it is. I cannot use the macro.
That is weird. Is there an issue about it on github?
@@minimal3dp Well i found the same issue in Issues. So it seems i'm not the only one.
Interesting, but useless for delta printers because it does nothing for Z motion.
This one is specific to Core XY. Take a look at Elis's Tuning Guide I spoke about last week. That has a Delta variant.

My print speed is relatively low, so the hotend should keep up. I will test a larger model.
