@dc42 4 flashes then it stops then 4 flashes. It’s asking for firmware update. I think.

dc42

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.

bam

@dc42 That’s probably the issue then because I am just using standard issue phone cord

@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

@bam fast flash is no connection to mb

dc42

@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.

@bam said in cannot get 3hc to connect.:

@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

Thar suggests a problem with the CAN wiring.

bam

@dc42 i just took a look and the wires are not crossed

@dc42 what does this mean?

Error: Unterminated string in line 3

bam

@dc42 and now this

Warning: Incompatible firmware, please upgrade as soon as possible

Veti

@bam said in cannot get 3hc to connect.:

M32 "0:/gcodes/Duet3Firmware_EXP3HC.bin"

M32 is start a print.

you want to print a firmware binary file?

and why is that file in the gcodes folder?

bam

@Veti i dont know why the file is in there, not sure how to delete either. mightve shown up with the .bin i downloaded.

this whole time ive just been trying to get the boards online and the software updated. I can config the printer later.

twisted pair wasnt actually twisted. just looked twisted.

Phaedrux

@bam said in cannot get 3hc to connect.:

not sure how to delete

Either right click and delete, or if that won't work, you can try and do it from the SBC side. The first SD card (0:/) is emulated by DCS and its default directory is /opt/dsf/sd

bam

@Phaedrux yeah theres nothing here so idk

Veti

you are editing a file called gcodes.g

nothing phaedrux said mentioned any of that.

bam

thanks for all the helps @dc42 @Veti @Phaedrux @bearer i promise you i will be back. have to make a hardware store run to find an (actual) twisted pair, not this spliced mess, and then start wiring motors and sensors.

bam

@Veti

Either right click and delete, or if that won't work, you can try and do it from the SBC side.

i did it from the duet3webcontrol.

sorry if i dont know anything about these and i jumped in feet first.
