Connect single board computer #4

Open khayrulinnikita opened 5 months ago

khayrulinnikita commented 5 months ago

Hello! As I understand it, the host does not have enough resources to run a clean klipper. Is it possible to connect a single board computer like orange pi or raspberry pi to the N32G455 microcontroller? And flash the microcontroller with a clean assembly of klipper.

Yees, but u need some soldering skills. The other day I started researching in search of an opportunity to connect to his system, I found what I needed. I'm going to upload photos to /photos now, you can explore them. I plan to make a board that will be mounted on racks above the main board. it will have a CM4 minicomputer and everything you need to connect to the current system, as well as a CAN output for the print head

@g992 did you only connect rx and tx or also the gnd from the usb to ttl adapter? I have the same adapters laying around as yours and I think I'm going that route instread of using the uarts of the rpi4 directly. That way, I can pry open a usb-hub with the 2 convertors and run a usb cable out of the enclosure. That way, I can keep my rpi external and easy to swap cards etc.

Using a sbc instead of the onboard t113 gives some more headroom and freedom. (extra gpio's for stuff like chamber temperature, ..., more storage, less contraints like ram etc). Still in doubt, but I can always switch back offcourse. The resistor you grounded goes to the reset pin of the t113?

gnd connected too, yes if u use stock program versions, don`t remember send symbol to head controller (https://github.com/g992/flashforge-ad5m-5mpro-research/issues/6#issuecomment-1942928934)
