USB ID Retrieval

Searching for USB ID

1. Open your browser, enter the IP address of the host computer in the address bar. For example, if my host IP is 192.168.101.179, just type it and press Enter.

2. Open the host's WEB interface. In the left sidebar configuration options, find:

For fluidd: {…}, click to enter, then find printer.cfg

For mainsail: Machine, click to enter, then find printer.cfg

3. Click printer.cfg to enter, then click DEVICES in the top right corner.

4. Click SERIAL, then refresh.

Refreshing in fluidd

Refreshing in mainsail

5. Copy the ID. Click where the arrow points to copy.

In fluidd, check if ttyAMC exists, and ensure Path by ID exists. This is the USB ID.

In mainsail, check if ttyAMC exists, and ensure Path by ID exists. This is the USB ID.

Filling in the USB ID

dangerous

Please note, the ID below cannot be used!!!!

serial: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

1. Close DEVICES and fill in the ID.

Important Notes

• In the configuration file, change:

[mcu] 
serial: /tmp/klipper_host_mcu

to:

[mcu host] 
serial: /tmp/klipper_host_mcu

• Add:

[mcu]
serial: <Replace this with the ID you just queried>

Find [MCU] in fluidd

Find [MCU] in mainsail

2. Fill the ID into the configuration.

tip

• After filling in the ID, click SAVE & RESTART in the top right corner.

3. If Klipper prompts ADC out of range, this is normal. Connect the heated bed and thermistor to the mainboard, configure the thermistor pins for the hotend and heated bed, then save and restart.
