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. In conclusion, I think E3D is doing the average user a disservice by still publishing the Edition 1 version of instructions.Experiment freely. Everything worked as expected and I no longer experienced any heat creep, clogging or extruder clicking. Once I had the Edition 2 mount installed with the stock fan, I was able to do some new tests with PLA. The stock fan also has a tachometer wire, so it doesn’t fail when doing fan self tests. I decided to print an Edition 2 mount and replace the tiny fan with the larger stock fan. Since the Edition 2 version of the hotend mount uses the larger stock fan, it is able to cool the heatsink more effectively. Both seemed like viable solutions but a little overkill and kludgey. Another option would be to rewire the fan wires to the board so the ground is attached to a different pin and that would run the fan at 100% at all times. It turns out the Prusa Mini firmware runs the hotend fan at 38% speed and there is no way to adjust that speed without modifying the firmware. The fan itself wasn’t to blame, it was a combination of factors. was it my esteps? did I need to PID tune? what was it? So I began to Google… Edition 1 vs Edition 2Īfter Googling and reading forum post after forum post with people experiencing the same issue, I came to the conclusion that the problem was the small fan that comes with the Revo Micro and the Edition 1 mount. I began printing again and the same thing happened again. I reloaded the filament and the filament purged out of the hotend like normal so there was no clog. I unloaded the PLA filament and the extruder had ground down a notch in the filament. Right away on the first layer, the filament started to click and grind in the extruder and nothing was coming out of the hotend. I was sold and ready to order another one for my other Prusa Mini! but I’m glad I waited… Heat Creep IssuesĪfter a few successful PETG prints with the Revo Micro w/Edition 1, I switched over to some PLA filament. The Revo Micro was tiny and cute and I was pleased with the upgrade. Installation was easy enough and I was up and printing with PETG in no time. While printing the Edition 1 mount on another Prusa Mini, I disassembled my hotend and got it prepared for the installation. Afterall, a fan that came with the Revo Micro would surely be better, right? I decided to install Edition 1, since using the old stock fan didn’t seem ideal. There was an ‘Edition 2’ set of instructions, but the only difference I could see was Edition 1 used the fan that came with the Revo Micro, and Edition 2 used the existing stock fan. Since there was no installation instructions I used the Google and eventually landed on the instructions for the ‘Revo Micro – Prusa Mini upgrade guide (Edition 1)’. However, there was zero documentation in the box, and if I didn’t lift up and look under the box insert I would have easily missed the extension cables. Unboxing the Revo Micro was straight forward. Revo Micro Installation on the Prusa Mini+ Finally! I had a good reason to dip my toes into the Revo ecosystem! I ordered a fully loaded 24v Revo Micro from Printed Solid and patiently waited for it to arrive in the mail. Fast forward to late spring 2022 and I had a failed thermistor on my Mini+. After all, my printers were working just fine…. The biggest feature of course, is being able to quick change a nozzle all while having no leakage between the hotend and the heat break.Īs cool as it looked, I held off and waited to try the new hotend system. It offers a lot of great benefits (with some added cost). The E3D Revo RapidChange system was all the buzz late 2021 and quickly sold out everywhere early 2022.
