![]() These programs import a CAD model, slice it into layers, and output the G-code required to print each layer. One method would be to use a slicing program such as Slic3r, Skeinforge or Cura. There are a few different ways to prepare G-code for a printer. Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications as well. The main target is additive fabrication using FFF processes. But as you can see, there’s quite a difference in size between these two objects.This page tries to describe the flavour of G-codes that the RepRap firmwares use and how they work. The difference in colour just represents which object is currently selected (brighter yellow is the selected item). To compare, let’s see the original object and resized object side by side so you can see the visible difference between the original and scaled items more clearly: If you mention you’ve looked at it in Cura, we will know that you are on the same page as we are. A lot of our time is spent emailing people back to talk to them about measurement expectations vs realities. This will help us because we’ll know you’ve already looked at it in Cura and that the measurements are accurate and not an estimate. Then in the Description area, tell us you’ve looked at it in Cura and that it’s a 0.5 scale (or whatever scale you are asking for). Recommendation: Once you have figured out the exact size that you want, input the measurements, in mm, as Cura shows them into the webform. In this case, it might actually be a little too short for a pen cup and could be scaled up to 0.6 scale, but this is just an example of how the scaling mechanism works. Looking at the measurements, you can see they are currently 52.52 mm x 47.36 mm x 49.5 mm, or approximately 5.3cm x 4.7cm x 5cm. You will now see a new approximate print time in the upper corner, new Size measurements (which you could then input into the webform) and a resized version of the original object (so you can see the physical change in the object size).Īs you can see, this print job is much more manageable at a 3 hour 22 minute print time estimate, rather than 18+ hours. Instead, make sure that Uniform Scale is locked (click on the lock icon) and then change the scale: Be sure to keep the Uniform Scale locked to keep your objects proportions when scaling, or it will end up skewed (image below): You can do this either by changing the scale (where it says Scale X, Scale Y and Scale Z), or you can punch in different measurements into the Size area (Size X(mm), Size Y(mm) and Size Z(mm)). If you change that scale, it will resize the image. If you look at this image, it’s currently at a “ 1.0 scale“, or the file’s regular scale, as is. A pen holder doesn’t need to be 10 cm tall and can certainly be scaled back. But as this is over 18 hours to print, we want to scale this back a bit. This is where we punch in the measurement values (in mm) and where you can get the measurements from to input into the print request webform. The second one is used for scaling the object (to make it larger or smaller). In this case, it’s over 18 hours, which is well over the 5 hour max guidelines that we require.Ĭlick on your object so that three buttons show in the lower left corner. You will see the approximate printing time show up in the upper left corner beneath the Load button. In this case, it’s a pen cup in the shape of a Stormtrooper helmet from Star Wars. The yellow object in the middle of the checkerboard space is the object stored in the. The first one that looks like an open file folder with an object hovering over it is the “ Load” button. stl file in CuraĪt the top left corner of Cura, you will see three buttons. Cura will show you a nice blue checkerboard space which represents the build plate / space on our 3D printer which will help you in seeing if your item is too large, too small, etc. It is free to download for Mac, PC or Linux. stl files for our 3D printer (Ultimaker2). Download CuraĬura is the software that allows us to prep the. Want to help us get through your print job a little faster? Here’s what you can do for us (and for yourself)! 1. I’ll warn that it’s a pretty popular service and it takes quite a while to process all the requests, get them printed, etc. So, you want to request a 3D print job? Awesome! We’ve got some info on the process on our website that you should likely have a peek at first.
