Firstly: My U1 arrived yesterday and it’s freaking amazing! Just for fun, I wanted to compare the print time and quality of the reference dragon between the U1 and my Creality K2 Plus. Here are the stats: on the Creality: nearly 23 hours print time, 590+ grams of waste from color change poop on the U1: around 3 hours print time, practically 0 waste (just the initial filament load poop) NOW, I started printing a model I’d printed before on my Creality. It prints on two plates. What I am baffled by is that the first plate on the U1 is taking over 11 hours while it took around 5 hours on the Creality. There is some color changing, but only really in the first 40 layers or so. The rest is all black. The Creality has a max toolhead speed of 600ms and the U1 is 500ms. But, I can’t imagine that difference accounts for an 6+ hour difference! I’d love some feedback on why there’s such a massive difference in print time. FYI: While the included screenshots below are estimates, I’ve now printed this model on both printers and the estimates are pretty spot on. Here’s a screenshot from the Creality slicer: [Creality Print time](https://imgur.com/a/y81xWel) Here’s a screenshot from the Snapmaker Orca slicer: [Snapmaker U1 Print Time](https://imgur.com/a/YKIhTK1) (ALSO, sidebar: why does the forum limit to 1 embedded image and 2 links per post?) ---

ok. I’m an idiot. It looks like the Snapmaker Orca slicer is defaulting to a layer height of 0.08mm while the creality slicer defaults to a layer height of 0.2mm. With a layer height that’s 2.5x thinner, no wonder it’s taking around 2.5x as long to print! ---

It’s not 2.5x thinner, the other one is 2.5x thicker. > **[Times Less Than](https://timesless.com/)** > > Have you heard some one say "times less than" or "times smaller than"? Here is why they are wrong. ---

I noticed a first Slice taking a long time and luckily that caught my eye 🤘 🤘
