Planning on finishing an ercf this year and going can for that so figured good opportunity to swap the hotend over, saved a substantial amount of wiring even compared to the hotend PCB I had, saved the wiring harness just to compare went for a usb can device over running can from the octopus pro, did want to swap the pro over to can as well but ended up keeping it the same instead of messing with reflashing firmware. Hotend has a little 3015 fan and a heatsink on the arm chip so cooling should be fine, looked up the datasheet and it’s got a tjmax of like 120c and rated for ambient -40-80c so don’t think I need to worry about it, if it’s an issue I’ll run a fresh air feed to it, will see how it likes abs in the summer shortly.

All in all, super easy swap over, definitely cleaned up my rats nest (though I still should cut the stepper wires to length, they hide in the imitation panduit I printed, it’s neat enough to be serviceable and not be a hazard), used katapult (formerly canboot) and then flashed klipper onto the board, only minor issue is it uses these tiny jst connectors, like really small, btt ebb sb2209 and btt u2c usb can device, was a good resource to follow for any of the network interface configs that I needed to do and gave some good details on diagnostics.
