cannot get 3hc to connect.

When the system has settled down, does the red LED on the 3HC flash in sync with the red LED on the main board, half a second pff and half a second on? If it doesn't then the CAN connection is missing.
I suggest you update DSF and RRF to the 3.2RC2, or alternatively run the main board in standalone mode until you have established communication with the 3HC.

@Veti that happened when I flipped the switch off
-
@dc42 when I had the main board on 3.2 it wouldn’t talk to the DWC
-
@dc42 4 flashes only on the 3hc
-
@bam said in cannot get 3hc to connect.:
@dc42 4 flashes only on the 3hc
Do you mean it flashes 4 times and then repeats, or something else?
What do you have the address switches set to?

PS - RRF 3.2 on the main board will need DSF 3.2 on the Pi to connect.
-
@dc42 4 flashes then it stops then 4 flashes. It’s asking for firmware update. I think.
-
The error codes indicated by flashes are lisated at https://duet3d.dozuki.com/Wiki/CAN_connection#Section_LED_behaviour_and_error_codes. Normally you would see alternating 2 or 3 flashes (indicating no valid firmware installed followed by 4 flashes. Anyway, 4 flashes indicates that the main board didn't respond. This normally means that either the main board is not running, or the CAN connection is broken or mis-wired.

@dc42 changed the can address switches on 3hc to 1, same as the config.g file. now we have a slow flash on the mb and a fast flash on the eb
-
@bam fast flash is no connection to mb
-
@bam said in cannot get 3hc to connect.:
@dc42 That’s probably the issue then because I am just using standard issue phone cord
That should be OK if it is short and wired with the middle 2 pins straight through; however it may be wired crossed.

Thar suggests a problem with the CAN wiring.
