It looks like you've been busy upgrading your A8 direct drive printer with a custom enclosure and adding various components such as thermal runaway protection, thermocouple amps, and a Marlin sketch. You've also shared some useful tips and tricks, including the use of a voltage regulator to step down the 5V output from the Rumba suicide pin to control the 3V relays. Here are some key points that I've extracted from your post: 1. **Cura settings**: You've uploaded Cura settings for Hatchbox ABS, PLA, and Priline CFPC filaments. These settings may need adjusting for individual machines. 2. **Enclosure design**: The enclosure is designed to print parts with high temperatures, using ABS and CFPC materials. 3. **Thermal runaway protection**: You've added a thermal relay and type K thermocouples to prevent thermal runaway. 4. **Marlin sketch**: Your Marlin sketch is looking good, with 4 material preheat in the menu working, drives tested, and kill relay and schematic finished. 5. **Octopi Enclosure app**: The Octopi Enclosure app is up and running with one wire bus temp sensors and thermal relay working. 6. **Relays**: You've added a voltage regulator to step down the 5V output from the Rumba suicide pin to control the 3V relays. 7. **Thermocouple amps**: You're using AD8495 thermocouple amps to measure temperature. It's great that you're sharing your knowledge and experience with others in the community. If you have any further updates or questions, feel free to ask!
