First print stops mid-purge line | VORONDesign | Page 1

First print crashes as soon as it goes to do a purge line. It actually crashes mid purge line:

Klipper reports: SHUTDOWN

MCU 'mcu' shutdown: Timer too close
This often indicates the host computer is overloaded. Check
for other processes consuming excessive CPU time, high swap
usage, disk errors, overheating, unstable voltage, or
similar system problems on the host computer.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

anyone can help?

I am running KAMP, wonder if CB1 cant handle it?

#

KAMP is just a config, it shouldn't tax the system. Are you running a camera or anything like that?

#

KAMP runs fine on a CB1

jovial pollen May 30, 2024, 2:52 AM

#

no camera or screen

#

I also got rid of KAMP and also did a bed mesh that is loaded in my starting g-code

#

cant get it to print anything

#

Anything in the Klipper log at the time of the shutdown?

jovial pollen May 30, 2024, 2:53 AM

#

now it just crashed at mid first layer

this klipper file has several crashes. All happened either in purge line or first layer

#

just crashes

I tried like 10 times, restarting etc between prints

ssh into the printer and execute the command shown. Does your output look like this?

Review this section of the wiki. See how your txqueuelen is 10 and not 1024?

Probably a typo in /etc/network/interfaces.d/can0

jovial pollen May 30, 2024, 3:05 AM

#

:(, full reflash needed or just fixing that typo?

#

just opened my can0

merry glen May 30, 2024, 3:06 AM

#

This is on the CB1 side. Fix the file and reboot the CB1.

jovial pollen May 30, 2024, 3:06 AM

#

#

looks correct?

jovial pollen May 30, 2024, 3:08 AM

#

merry glen This is on the CB1 side. Fix the file and reboot the CB1.

See above here

#

sorry for the tiny screenshots

merry glen May 30, 2024, 3:09 AM

#

Are you using the official biqu images. V2.3.4 or something?

#

NVM. I see that you are.

jovial pollen May 30, 2024, 3:10 AM

#

I followed the steps in the guide so I assume yes

#

only step I skipped for now is this:

because im not using a screen yet

merry glen May 30, 2024, 3:11 AM

#

That won't matter.

jovial pollen May 30, 2024, 3:12 AM

#

yeah just thought id mention (dont wanna be going off any assumptions)

#

so :D, what to do to print plastic 😄

merry glen May 30, 2024, 3:13 AM

#

jovial pollen so :D, what to do to print plastic 😄

Fix your typo...

jovial pollen May 30, 2024, 3:13 AM

#

theres no typo I just showed you above

jovial pollen May 30, 2024, 3:13 AM

#

jovial pollen

here

#

thats the file I opened and it was correct

merry glen May 30, 2024, 3:14 AM

#

jovial pollen theres no typo I just showed you above

Are you a betting person???

jovial pollen May 30, 2024, 3:14 AM

#

merry glen Are you a betting person???

I am not trying to troll or be stubborn, should I still restart? thats the file unmodified, I simply opened it

merry glen May 30, 2024, 3:14 AM

#

jovial pollen May 30, 2024, 3:15 AM

#

ah

#

LOL

#

so sorry

#

its late,

#

thank you so much let me try

merry glen May 30, 2024, 3:16 AM

#

Because of that typo, there was almost no transmit queue for canbus.

jovial pollen May 30, 2024, 3:17 AM

#

when you say restart CB1, can I just restart entire printer?

#

or need to restart it via SSH?

#

ok lets test it

merry glen May 30, 2024, 3:20 AM

#

shutdown -r 0 on the cb1 would be enough.

jovial pollen May 30, 2024, 3:21 AM

#

I did a reboot

#

trying a print now, fingers crossed

merry glen May 30, 2024, 3:22 AM

#

Same difference. Do that same ifconfig can0 command from ssh to double check.

jovial pollen May 30, 2024, 3:23 AM

#

yep works now

#

like ur output

#

ure the man, lets see if this print works

merry glen May 30, 2024, 3:23 AM

#

It will

jovial pollen May 30, 2024, 3:24 AM

#

alright, how do I close this post?

#

!solved

#

!closed

#

!close

#

hmm 😄
