While doing some research on updating the Marlin firmware on my MendelFlex, I came across a few good resources. First I need to save my current settings by using a program like Pronterface. Inside of Pronterface I connect to the MendelFlex and then send a M503 command which tells the printer to list its settings. I then copy and save that information into a file for later use. Then I edit the Configuration.h file and change certain settings. I will also be using my old Configuration.h file for reference. Unfortunately it was not the latest file. After editing the file I need to open Marlin file in the Arduino Ide. I downloaded and installed version 2.2.1 of the ide. While I attempted to load up the Marlin files in the ide, it only got so far and then the ide froze. In fact my laptop froze and I couldn’t even Ctrl alt delete it! Tried it again running the ide as Administrator but same thing happened. I tried down loading the latest nightly version (which is like version 2.2.2) of the Arduino Ide and the same thing happened. Was looking online to see if anyone else had this issue. I haven’t found a good solution.
I decided to install an earlier version of the Arduino software. Version 1.8.19 doesn’t have the Ide moniker tagged to the name. I was able to verify it worked successfully with Marlin 1.1.9.1. While it did run, I did have two errors I needed to fix. After I fixed them, I ran the verification step and got a clean compile. After I that, I was able run the load process and was successful putting Marlin 1.1.9.1 on to the MendelFlex.



There were a few more things I had to set in the configuration file. I thought I enabled the SD card reader, but I hadn’t. I am at a good point now with my settings. I am expecting a filament dryer this week sometime. I will need to make sure the 3mm filament I have for the MendelFlex is dry enough to use. The filament picks up moisture over time and my filament is old. This can cause trouble with your prints. When I start printing, then I will make sure I have a good Z offset. That’s all for now, catch you later.
