![]() ![]() No Firmware changes are required for this upgrade. This means you will not need to buy any additional nuts and bolts to complete it. The upgrade has been carefully designed to reuse the existing fixings on your Mini. The upgrade should take approximately 1 hour & 20 minutes. ![]() You should read through the whole guide before attempting the upgrade to ensure you understand exactly what is required to successfully complete it. Please note, your printer may vary from the one illustrated in this guide, depending on the model and your own upgrade choices. This is a complete upgrade guide suitable for an original Prusa MINI+ and Revo Micro. We recommend using edition 2 as it passes Prusa's self-test. It’s potentially a little overkill, but it’s the details that matter! Your ObXidian should arrive in the same pristine condition that it was in when it left E3D.Before upgrading your Prusa Mini with the Revo Micro please read the following safety cautionsĪfter requests for a mounting option using the original fan, we’ve created a second edition of our Prusa Mini upgrade guide that retains the original Prusa HotEnd fan. These VCI molecules form a thin, invisible layer on the Nozzle which prevents oxygen from touching it. This paper is chemically coated and produces gas progressively over time. It is VCI paper which stands for ‘vapourised corrosion inhibitor’. The brown slip of paper is there to offer corrosion protection for metal parts during shipping and storage. Why is there a brown slip of paper packaged in with my ObXidian Nozzle? Turns out it’s a lot more complicated than wear being proportional to speed, but we’ve been using the Prusa MK3S+ with the 0.2 Quality settings with good success for most model geometries. We’ve successfully run multiple kilograms of glow-in-the-dark filament through an ObXidian Nozzle without seeing any impact to the nozzle's performance. We’re not saying you need to totally avoid using glow-in-the-dark. We’ve found these conditions to be capable of removing the E3DLC coating and therefore can have a permanent impact on the wear resistance of the nozzle. So hard, in fact, that when printed at very high movement speeds, the deposited layers begin to work like sandpaper. UV-reactive/ “glow in the dark” filaments include an additive called Strontium Aluminate. That’s not to say they are indestructible though we have successfully worn ObXidian Nozzles in some extreme testing. Our testing has shown that under normal printing conditions, even when printing abrasive materials, ObXidian Nozzles can last almost indefinitely. Is it possible to wear out an ObXidian Nozzle? If you’re a printer manufacturer using 3mm, please reach out! What HotEnds are Revo Nozzles compatible with?Īny of our Revo range are compatible with ObXidian. For the literal icing on the cake, the assembly is then coated with E3DLC™. Then we have a steel tube, and finally, a copper threaded portion. Starting at the Nozzle tip, we’ve got a specialized hardened steel, with the rest of the nozzle portion being made up of Copper. ObXidian is made up of many materials and processes. ![]() However, 0.25mm nozzles still benefit from the reduced stick properties of the E3DLC coating. We do not recommend the use of abrasive materials with 0.25mm nozzles. The particle sizes, especiall y with fibres, can often be larger than 0.25mm, significantly increasin g the risk of clogging the n ozzle. You may need to adjust your Z offset when changing nozzles. Revo™ Nozzles are not compatible with V6-style heaterblocks Meaning considerably less plastic build-up around the Nozzle. This specially formulated coating also embeds non-stick properties into the Nozzle itself. With a wear resistance that is orders of magnitude higher than any other E3D nozzle, ObXidian is really hard. This is achieved by pairing a tool steel insert with our new E3DLC ™ coating. Identify nozzle sizes at a glance, thanks to a colour-coded silicone sock. Plus, each Revo Nozzle has its size engraved into it with easy-to-read numbers, so there are no confusing identification markers to learn! Say goodbye to frustrating HotEnd leaks and enjoy reliable 3D printing! Each Revo Nozzle is a preassembled nozzle and HeatBreak in one unit, so there’s no hazardous hot tightening and no chance of incorrect assembly. Print large objects in less time or tiny objects with high resolution.įrustration-free. Set your 3D printer up for ultra-fine or ultra-thick extrusion widths in no time at all. With nozzle swapping this easy, you’re free to experiment with nozzle sizes you might not have used before. ![]()
