![]() In conclusion, I think E3D is doing the average user a disservice by still publishing the Edition 1 version of instructions.No machine redesign. 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.
