Btt EDDY Can setup on SB2209

[rotund compass]

Which SB2209 do you have?

[minor quartz]

SB2209 CAN V1.0

[rotund compass]

I would follow https://canbus.esoterical.online/toolhead_flashing.html and make sure you have it setup for CAN and then I think you connect it on the front board.

[minor quartz]

yeah it is connected on the front one i think it is flashed right so it is more the config part i need help with i just tried to add [mcu eddy] canbus_uuid: 5b9eeffabe63 and if i pull out the cable from the eddy and start up the printer it says it wont start bcs there is nop connection to mcu eddy and it turns on when its pugged in so i think all there is good

If the LED's are flashing I think we only have katauplt and not klipper. Do you see that in the UUID scan?

[minor quartz]

leds are contant on

[rotund compass]

Can you screenshot the menuconfg you used (from what is on your printer and not the guide).

[minor quartz]

sure

[minor quartz]

i made it by flashing for usb first and then flashing for can after using the usb connection

🤔 I see no bootloader which would remove katapult and I'm also not sure that is the correct memory for the board.

[minor quartz]

do i need katapult the guide says i can do it both with or without katapult that is what is so confusing xD

[rotund compass]

I use it on all of my CAN boards so I can re-flash them remotely say with https://github.com/fbeauKmi/update_klipper_and_mcus

[minor quartz]

so it would be smarter to flsh with katapult?

hmm wait a moment printer is up and running i see the eddy temp also so something is right i will try to play with the z homing then

[minor quartz]

so i got it working i think i can run the calibration but when i try to home it in z axis it gives me Invalid probe_eddy_current height
