The printer is not ready on Klipper

Basic Information:

Printer Model: Anycubic i3 Mega S
MCU / Printerboard: Trigorilla+A4988
klippy.log

Hello, everybody!
Yesterday I installed klipper on my Anycubic i3 Mega S. But I can not to do config file for it.
klippy (4).log (4.7 KB)

According to the log, you probably never set up the virtual host MCU.
Run make menuconfig via SSH again and this time select “Linux process”, then run “make” and it should create it.

that’s right, I’ve never set it up, and then what should I do next?

The installation of a host MCU for a Pi is thoroughly described in the official documentation.

I did everything according to the instructions, but a new error came out
But I didn’t collect on raspberry pi I collected on ubuntu
Unknown pin chip name ‘rpi’

Once the underlying issue is corrected, use the “RESTART”
command to reload the config and restart the host software.
Printer is halted

You need to post a new log.

here is the new log
klippy (6).log (31.2 KB)

[mcu host]
serial = /tmp/klipper_host_mcu

[adxl345 hotend]
cs_pin = rpi:None

[adxl345 bed]
cs_pin = rpi:None

You have called your mcu “host” but you try to access it under the name “rpi”, hence the error.

I fixed everything here is a new log and an error
klippy (7).log (42.2 KB)

Printer is not ready
The klippy host software is attempting to connect. Please
retry in a few moments.

It might be helpful if you would read and setup your printer according to the documentation provided for example https://www.klipper3d.org/ or Installing Klipper with KIAUH since every topic is clearly due to either not reading or not following this information.

See Installation - Klipper documentation

I did everything the same way there

ttyUSB1 is not the correct serial device for your primary MCU.

MCU ‘mcu’ shutdown: ADC out of range
This generally occurs when a heater temperature exceeds
its configured min_temp or max_temp.
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

Here is a new error and there is a yellow note

Your bed thermistor is disconnected, not working, or you configured the wrong pin.

edit: Sorry, guess I mixed up your klippy.log with somebody else klippy.log.
Again sorry, my fault!

Good luck, hcet14

I installed the klipper correctly but I can’t do the printer config

MCU 'mcu' shutdown: ADC out of range

This usually means, there are issues with the thermistors.

Are they connected properly?

You can’t do tests without them.


I did everything right, but it did not start until I set the minimum temperature to -100, but when I heat it, it does not show what it has heated and goes into error, but the table is hot everything else works But everything is OK on Marlin

I believe you, but is the hardware (cables, thermistors) ok?

Do you really want to use -100°C

Is the correct pin used and defined in the respective section?
You could swap hotend and bed thermistor connection on the board and check whether the issue stays or follows the thermistor.
