BTT Manta 8P with CB1 has arrived and rewiring of the machine has started ! Original wiring was to screw terminals and the new electronics use JST or Dupont pin style ! I'm also converting it to 24 volt and Klipper. Lots of online youtube for these boards but none about fitting to older printers. Sample config files are usually for and Ender, Voron or Creality so it is a challenge !by Bill_of_the_North - Mendel90
At this point I just have to accept that they don't work anymore. The adventure will continue when the BTT Manta 8P with CM1 arrives and I start to learn about Klipper, Octoprint and all the newer environs. As the Pi 4 when available is expensive compared to the CM1 Pi 3 equivalent, and BTT seems to have fostered a growing community around their products how bad can it go ? It's winter here wiby Bill_of_the_North - Mendel90
Addendum(b): Measuring across the the input terminals for temp sense on all 3 boards confirms my suspicions. 2 boards have low resistance on the E-Temp compared to Bed temp. The 3rd board has unrepairable phsical damage yet temperature inputs are the same as the working Bed temp inputs of the other 2. Thank you all for your time and thoughts. I'll be back with questions when I get the new boaby Bill_of_the_North - Mendel90
TH3D has some DIY videos and guides to get VSCode and Marlin sorted. They also have links to pages with repositories for various code you need and how tos. There guide on installing a boot loader to a Melzi board was the only one I found. Billby Bill_of_the_North - CoreXY Machines
I was using the E3D before without problem. The heat block did get hot VERY quickly and the thermistor value at the board input showed that. After a lot of reading, searching and shopping I've ordered a BigTreeTech Manta 8P with the companion CM1 RPi equivalent. According to Teaching tech it is closer to a Pi 3. The board ticks a lot of boxes in that it will run Marlin or Klipper, can alsoby Bill_of_the_North - Mendel90
I've run out of ideas to try at this point so I'm looking for a Smoothie board. I like that it is flexible in application to tasks other than 3D printing.by Bill_of_the_North - Mendel90

I now have fewer things to check ..... Changed the thermistor in the E3D V6 Hotend as it seemed intermittent. Recompiled and uploaded with "TEMP_SENSOR_0 5" as I believe that is the correct one as per E3D. Double checked continuity to the board from terminals on on the Hotend assembly. Using a hot air gun verified resistance change. Still get the same error ! Beginning to suspeby Bill_of_the_North - Mendel90

Thank you ! Exactly what I neededby Bill_of_the_North - Sanguino(lolu)
I am trying to resurrect a Mendel 90 and get the latest Marlin from nophead on it. I cannot find a way to get 'Sanguino' to appear in the Boards menu. I have managed to 'burn a boot loader' using a utility from TH3D but beyond that I can't find Sanguino or Melzi 1284p anywhere ! What am I missing or better yet how do I get it ? Thnx in advanceby Bill_of_the_North - Sanguino(lolu)
It is a replacement board as the original was physically damaged by parties unknown when I moved to the Great White North. I have now managed to get a boot loader installed. Currently trying to compile the updated marlin with a borrowed Windows machine. Maybe I should look at the visual code method, but I am not a programmer nor familiar with VSC. Will need to search out how that is done !by Bill_of_the_North - Mendel90
Progress .... sort of. As I try to refresh the software toolchain I now have Pronterface running under Ubuntu 22.04 ! Python issues ! Connection to printer is the issue now. I have permissions set properly and the on board UART is reporting. It will not connect regardless of baud rate. I suspect I need to reprogam the board.

I have been out of the tech for 5-6 years and have just unearthed my 2013 Mendel 90. As I am reconnecting it I need to get software, and perhaps hardware to make it work again. I am running Ubuntu 22.04 but installs of Printrun / Pronterface crash on launch, Slic3r fails to install and I suspect the world of SW and HW has moved considerably from where I saw it 6 years ago.
