Cura Settings in 5 Minutes or Less! 7.0 - Cooling

Hi folks, TechNiverse here. Welcome to my Cura playlist. Before we get started, hit that subscribe button so you can find your way back here. I update often. That said, as you may have noticed, Cura settings can be very simple or very in-depth. So I took the time to make a video about each section in the custom settings menu and I'm going to quickly go over the important settings each section contains and briefly explain them. Are you ready? Good, let's go. This is Cura settings in five minutes The next setting we're going to go over is a big one and this one is also going to be usually more filament specific than machine specific. And what I mean about that is it is the cooling factor. Now the first setting you have under cooling is enable print cooling and basically that turns your part cooling fan on and off. There are a bunch of other fan settings that regulate the fan and you can adjust it to be set as a certain percentage at a certain time and yes that's all well and good. But if you don't know what filaments require fans and what filaments don't, you're going to have some problems in this regard. So here's a couple of quick tips. PLA generally you want to have a fan and it works really well. The higher the fan speed the better it works. That's not really a law but it's general rule. It works pretty well and in some cases of hybrid materials that are really PLA like PETGs, you're going to want to a little bit of a fan but not much. For most PETG products you're going to want to have the fan completely off or down really low below 20 percent. And for ABS products you're not going to want the fan on at all. Basically that's going to cause a cool air gap between the nozzle and the bed and it will warp and crack your prints. Now there are ways around that in the special settings we will talk about that later. But there are several other types of filament and it's important to know before you start a model when working with a new filament those filament specific settings. You can generally find those on the side of the box, on the side of the spool, or on the company's website. So basically anything you're going to be putting in here should be something that you either know because it is something you're experienced with or you actually went and checked to see if that particular plastic should have a fan. Now like I said it's a general rule that most PLAs are going to have the fan turned on. You don't need to check for every different brand of PLA that you get. But if you have problems such as stringing or warping or cracking this is one of the first things that I would go to and find out. Because maybe you have a rarer form of plastic and it's not meant to have the fan turned on. A couple of the settings that are in here under enable print cooling you have your fan speed. You can change this. It will also affect these two. You can change these independent of this and it will remain the way that you set it. Normally I leave it on 100% when I'm printing with PLA as I am here even if it is a infused PLA. So I have no issue with that. Initial fan speed is zero. This is basically saying I'm not going to turn the fan on for the first layer because I want it to be nice and gooey. I want it to stick to the bed and then once I put down a layer or two, basically in this case four layers, it's going to turn that fan on and add about 10% and then it's going to gradually increase the fan until it's at full speed over the next couple of layers just like we talked about with the print head but in reverse.
