Dear all , I'm looking for help.
I'm using this toolboard from bigtreetech onto my voron 2.4 r2 https://bttwiki.com/EBB SB2209 USB.html
I'm having issue during print ,after fews minutes klipper lost comunication with the toolboard. So far within the documentation grounding of the steppper motor requested/done, the heatsink installed; no information found inside documentation where to install, 2 spots possible.
After adding a fan onto the pcb tool head i'm able to print for about 20 min now.
I'm not sure it is a heat problem related, or pcb issue or usb cord/conection/interference?
Any hint to start with?

For the EBB42 that is commonly used in the ratings, the most common cause of "lost communication" is a flakey USB cable. Check those ends and provide some physical immobility.like zip ties or hot glue. Also looks like there is a separate non USB cable that goes from a small breakout board TO the toolhead, check those connections as well

well, i've replaced the cheap usb-c/usb-a cable provided with the board, seems to do the trick. I was able to achieve a print of 52 min without issue!
