So I have been building a Voron 2.4. I have tap sensor, Xol toolhead with btt ebb36 can bus. Everything was working. Did several prints. Decided to build TradRack mmu. Followed steps from github. After steps to instal were complete my printer will no longer load Klipper. Tried rebuilding SD from scratch and now I cannot reflash board using putty. Tried reinstalling bootloader using stem32cube. I was able to flash from sd card and file name changed to .cur. But kilpper will still not load and finally times out with error. Everything worked good before installing the TradRack. I am running the Octopus Pro 723 board. And the MMU board I was using is the Easybrd. Used kit from Triangle Labs. Any guidance would be appreciated.
