I’m curious to learn more about how sport and Ludacris speeds affect the presets that I’ve entered for my specific filament. For example, I use a third-party filament and have adjusted my A1 printers, speed and temperature settings based on the manufacturers recommendations. If I’m halfway through a print, and I suddenly decide to kick it up to Ludacris speed, does it scale my settings somehow or does it completely disregard my settings in favor of moving faster?
The understanding is, everything is increased by the ratio percentage shown on the screen when you change the speed.
Anything you told the slicer is then scaled accordingly.
This is why you should babysit the printer when exploring the speeds and especially with models you haven’t printed before.
The worst case scenario os your hot end getting caked in filament in a massive blob becuase something went terribly wrong.

You do realize that at faster speeds you may get lower quality prints, or faster accidents!
Typically slowing down a first layer with silent mode can help adhesion / quality.

I haven’t tried the fastest speed but I did try sport, during a print I turned it on and off and it seemed to work fine. Print quality did not seem affected but it was a simple part.
That was with pla basic, I did have an issue with pla matte grey where running it at silent seemed to give better print quality. Other matte filament seems fine so not sure why the grey is an issue.
Edit: the matte gray actually failed the print at normal speed, the tree support broke.

Every owner prints differently, the printers are at a point where they are appliances. You can start a job and go to bed…
In my case I usually set specific speeds in the prepare tab.
Once that is configured I start the job and let it run, usually at standard speed.

I did a Benchy on ludicrous.
I was showing off to my friend’s kid how fast even the A1 mini is.
It came out great.
This is good advice though.
And this.
Maybe i’ll try ludicrous on my next pla basic part.

I will update when the print finishes, if it does.
Soundtrack should be flight of the bumble bee…
L00l, the print did finish fine.

That’s great.
What was the item that you printed?
A simple tongs.

I scaled it up a bit to max out the bed space.
I am printing multiple train trestles I designed for my son’s model train set so I finally gave in and printed a batch at Ludacris speed. The print went from 14 hours to 8 hours and the quality is acceptable for my application. I designed a small 2.15mm peg on one of the pieces to fit inside a hole on the main structure and was concerned the dimensions would not be right printing that fast due to loss of resolution/detail, but the pieces fit together fine. I also designed some rivet detail that I assumed would be lost, but they turned out fine. Because I printed the same piece at standard speed, sport and Ludacris, I was able to compare the relative build quality. The standard speed printed the surfaces more smoothly, but other than that, I really can’t see any difference in quality between the speeds. For me, the roughness is actually better because I want the trestles to look like they the are made out of rough iron. I do agree with others though that if you do have a problem, you are going to end up wasting a lot more filament printing at higher speeds unless you are constantly monitoring your print. I tried uploading a photo of the print, but the Forum won’t allow me to post a pic or link to pics.
