#ml13workshop 02/18/21 Last Christmas Santa brought me some sweet upgrades for my Ender 3 Pro. I got the upgraded glass bed, a Capricorn Bowden tube, and the BL Touch sensor to self-level the bed. This may sound dull, but for a guy like me, it is all very cool. Last weekend was the first opportunity I had to do the upgrade for the BL Touch. Before I could do that I had to flash the firmware and install a bootloader onto the board. I had watched several YouTube videos that went about this in different ways. In the first video, I watched they recommended using a USB microcontroller programmer downloader and ordered one, and I couldn't get the computer to see it. I then mucked around in Terminal trying to get it to work and then guesses that maybe I had a bad part. I ordered a replacement controller and discovered that the controller was fine, but discovered it was an issue with the drivers, then I spent the next two days trying to get the drivers to run on my computer. I then found a workaround for the driver issue. This involved removing the bottom panel off the bottom of the electronics box and connecting Dupont leads from my Arduino Uno to the Ender 3 Motherboard. Then uploading the TH3D Marlin software from my laptop using Arduino IDE (Integrated Development Environment). It was only after all this I discovered I had forgotten about the directions that came with the kit, which included a small piece of hardware that would have let me do all this through the Micro SD port. This once again proves that the hard way of doing things can be the best teacher. I can be stubborn and blindly power-thru until I figure things out. I am finding I have a growing appreciation that it is much easier to have someone over your shoulder to tell you that there is a better way. #3dprinting #fabrication #maker @thingiverse #thingiverse #ender3 #ender3creality #creality #cad #design #th3d #ArduinoIDE #TH3DMarlin #TH3D #Marlin https://www.instagram.com/p/CLdaJ-bjb5S/?igshid=1ce5e7gqcj3al
