Hi guys, recently installed this with the help of some of the guys in this discord, did some first layer test print then suddenly I got this error
and now, even after restart, doesn't seems like ebb is reachable anymore.
😭

📎 klippy_5.log

#

completely powered off everything, turned it back up and it seems to be responding again

#

but...not sure what the timer too close supposed to point to

#

This sounds like a Pi/Pi Alternative issue. What are you using for a host?

frosty sparrow Dec 22, 2023, 9:21 AM

#

CB1 with M8P

sly silo Dec 22, 2023, 9:28 AM

#

@frosty sparrow Are you using a single config for your Manta and EBB or are they two separate configs?

frosty sparrow Dec 22, 2023, 9:30 AM

#

they're separated

📎 ebb36.cfg 📎 printer.cfg

sly silo Dec 22, 2023, 9:31 AM

#

And you added the proper UUIDs to both and took out the serial calls?

frosty sparrow Dec 22, 2023, 9:31 AM

#

I put the correct UUIDs to each of the config, yes

#

but what is serial calls?

sly silo Dec 22, 2023, 9:34 AM

#

If you’re using the BTT sample configs they have lines that list the serial number for the boards. That’s used to address them, like the UUID does, but you need to remove it when you add canbus.

#

Do you have the host listed also

#

And do you have the include for the ebb? I’m on mobile, so I can’t look at your config yet.

frosty sparrow Dec 22, 2023, 9:37 AM

#

ah no I don't

#

on printer.cfg, I only declared mcu canbus uuid

#

on ebb.cfg i only declared ebb uuid there

#

what I'm not clear about is, if I need to declare all of the uuid in printer.cfg or ebb.cfg

#

and you said to take out any serial which I never had in the first place

sly silo Dec 22, 2023, 9:46 AM

#

Did you use the BTT example configs?

#

@frosty sparrow

frosty sparrow Dec 22, 2023, 9:46 AM

#

BTT example configs for m8p or ebb?

sly silo Dec 22, 2023, 9:47 AM

#

Yes.

frosty sparrow Dec 22, 2023, 9:47 AM

#

i have both, do you mean both or just one of them?

sly silo Dec 22, 2023, 9:48 AM

#

Both. Did you use them for your current configs and then modify them or start from scratch?

frosty sparrow Dec 22, 2023, 9:49 AM

#

i originally used BTT example config which I tweaked it for stock ender 5 pro, then continued on from there to merc 1.1, then now with ebb

sly silo Dec 22, 2023, 9:49 AM

#

Ok hang on.

#

try adding this:

[mcu CB1]
serial: /tmp/klipper_host_mcu

to the top of your printer.cfg. The rest looks good. So if that doesnt help, you have another issue with the CB1

frosty sparrow Dec 22, 2023, 9:55 AM

#

something has gone awry, when I check canbus query, it came up with no UUIDS found

#

was working okay last night......

sly silo Dec 22, 2023, 9:56 AM

#

Yes, thats correct. Klipper will only report can devices not in use. Since yours are in use, none are found.

frosty sparrow Dec 22, 2023, 9:56 AM

#

do you make canbus cable yourself? i used 18AWG for power and rj45 for the signals as they're twisted

#

so the fact that it found none means it's working okay? cuz I'm getting this

sly silo Dec 22, 2023, 10:01 AM

#

No, I used the premade LDO and crimped it. The RJ45 is solid core?

frosty sparrow Dec 22, 2023, 10:01 AM

#

this is what I see in klippy.log

#

yeah RJ45 is solid core

sly silo Dec 22, 2023, 10:01 AM

#

Thats a lot of movement for solid core wire

#

Do you have a multimeter?

frosty sparrow Dec 22, 2023, 10:02 AM

#

yeah

#

check for wire continuity?

sly silo Dec 22, 2023, 10:02 AM

#

You can check the can connection

#

no resistance

#

Klipper reporting back 0 devices doesnt check comm cables

#

it only knows there is nothing new

#

you want to check the can cable at one end, either the ebb OR the manta

frosty sparrow Dec 22, 2023, 10:06 AM

#

so signal cable continuity is definitely ok

sly silo Dec 22, 2023, 10:06 AM

#

no resistance

#

at one end for the can side with everything connected

#

powered off

frosty sparrow Dec 22, 2023, 10:09 AM

#

when you meant no resistance, is the same as continuity right?

#

it's like when I wanna check if a cable is okay?

sly silo Dec 22, 2023, 10:14 AM

#

Sorry, check resistance

frosty sparrow Dec 22, 2023, 10:18 AM

#

i just fixed the crimp and i think it was it

#

the shaking from input shaper potentially caused it came loose

#

everything is talking again now

#

by the way, this crimp came with ebb

#

I have some crimp kit but none of them fit

#

or is the right size

#

do you know what the size is?

#

so that I can get more

#

i only have like 4 left as i had trouble crimping rj45

#

sly silo Dec 22, 2023, 10:23 AM

#

microfit 3.0 i believe

#

the rj is super small for that. i would consider moving to a stranded core at 20-22 AWG

frosty sparrow Dec 22, 2023, 10:26 AM

#

ok, so power can stay at 18AWG stranded core

#

and for signal your recommendation is 20-22AWG? stranded?

sly silo Dec 22, 2023, 10:28 AM

#

Yeah. The cable I have is smaller than both of those and I wish they were a slight larger. Would have been an easier crimp.

frosty sparrow Dec 22, 2023, 10:29 AM

#

wouldn't thicker cable introduce more resistance?

sly silo Dec 22, 2023, 10:29 AM

#

If it’s in good shape for a fairly short run, no. Negligible at most.

frosty sparrow Dec 22, 2023, 10:30 AM

#

thanks again for your help!

#

I'll keep this open for now just in case 😅

sly silo Dec 22, 2023, 10:30 AM

#

I would marked it as solved since the issue was addressed and anyone else needs the info. You can always open another.

frosty sparrow Dec 22, 2023, 10:31 AM

#

ok

#

by the way, what's your first layer and first layer infill speed?

#

just out of curiosity 😅

#

for PLA

#

oh and how do I set this to solved? can't find the tag for solved

sly silo Dec 22, 2023, 11:36 AM

#

frosty sparrow by the way, what's your first layer and first layer infill speed?

Sorry just saw this. you edit the post and there should be a tag drop down

#

I run my first layers slow a good base is crucial, no reason to make it faster than need be
