![]() ![]() Start taking the heater and thermistor out of the cable sleeve and place the Prusa HotEnd on the heatbed for now, we will handle the wiring later. You can leave the fan where it is, as we will be reusing it in the next few steps.Ĩ. Now with the HotEnd assembly loose, you can remove the final fan screw. The whole HotEnd assembly will now be loose, so be careful.ħ. Remove the screw above the fan which holds the heatsink. Remove the screw that sits underneath the fan.Ħ. Remove the screw that connects the pinda arm to the heatsink.ĥ. Remove the arm and set it aside, you will need it later.Ĥ. Remove the screw that holds the cable management arm in place. You can use a wrench to get a better grip on the fitting.ģ. Loosen the upper fitting and remove the Bowden tube from the HotEnd. It is a good idea to keep your screws in a small container while you are working on the printer so that you don't lose them!Ģ. This will help ensure you do not strain the wires. ![]() Use the 2.5mm hex key to remove the screw holding the part cooling fan in place and then carefully twist the fan upwards as you remove it. You should also place a cloth or piece of fabric over your heat bed to give it some protection in case you drop something onto it.ġ. You should also ensure there is no filament loaded and that the printer is unplugged from the power source before starting. Move your extruder to roughly the centre of your bed and around 100mm above the build plate before starting the upgrade, this will give you easier access to the extruder. Revo Micro 24V variation (Please double check your own voltage, all original Prusa Mini's are 24V).Ĭheck out our blog if you are unsure on whether you need a 12 or 24V Revo Micro:īefore starting disassembly, you should make sure your Mini is on the latest firmware from Prusa.The files are named fan-spacer-clip and minda-holder. Just download and print them from the link above. MINI+ superseded the MINI, but the printed parts are reverse-compatible. If you have an early release of the Mini, you may find that yours doesn't use the cable management arm or potentially has the older version of the Minda holder. If you need a replacement or want to reprint it in another colour scheme, you can find the original STL here: ![]() You will need to reuse the cable management arm on your existing Prusa Mini. Presliced Gcode and a support enforcer STL are provided.Ġ.4mm nozzle or smaller, 0.2mm layer height or lower Print with the E3D logo facing up as shown Recommended materials: PETG, ABS, ASA, Nylon, PC blends, etc. It's also very important that the Revo micro can be screwed into the plastic thread. The M3 screws should easily thread into the plastic and (if you are using them) the square nuts should slide into place. Make sure you check the tolerances of the printed part before beginning the upgrade. Alternatively, if you want a stronger connection, we have also provided a second STL with slots for M3 square nuts. This version is shown in the illustrations and is the default option. This is sufficiently strong and it means you will not need any additional fixings. In order to make the upgrade as straightforward as possible, the part is attached by threading directly into the plastic. To begin, you need to make sure you have this part printed in advance:ĭo not begin disassembling your printer until you have printed this part or you risk being unable to complete the upgrade! 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. 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. Before upgrading your Prusa Mini with the Revo Micro please read the following safety cautions ![]()
