3D Printing

Printers: I am using the Prusa MK4 and I am very happy with it. I had the Prusa MK3S+ and Ender V3 in the past. I have built several printers or worked on others. The MK4 is my choice for my hobbies. Filaments: Humidity It is very important to remove the humidity, the results are tremendous. I use the EIBOS:  EIBOS 3D Filament Dryer Series X: Easdry – EIBOS3D They send from Europe. I also use their bags and vacuum to store filaments that I won't use so often. Wood PLA : Very briddle - hard to print, recommended to use a 0,6 nozzle. I need to try to remove the humidity to see it it works better. PLA and PETG: on this MK4, I print any PLA or PETG really... so I don't care too much, just buy the cheapest one. If I want something good, I buy Prusament. LW-PLA: This is mostly for airplanes - Coloprfab is my current choice, but order a new from amazon:  PolyLight 1.0 LW-PLA Natural 1 kg 3DLabPrint : Amazon.de: Business, Industry & Science  to try next week. Really important...

Setup INAV for planes

 This is how I setup my planes with INAV: Choose a compatible controller, I typically use Matek board. Download and install the INAV configurator:  Releases · iNavFlight/inav-configurator (github.com) Flash the board - to flash, you need to switch the board to DFU mode - tipically, press the button on the board while powering the board. If it is not recognized, run Zadig or  ImpulseRC Driver Fixer I like to start from a fresh model, so make sure to clean the settings.
