Search RS232 ID

Precautions before searching for devices

• Before searching for RS232 ID, please ensure the following conditions have been completed
• Please make sure the tool board has been burned with RS232 firmware
• Please make sure the tool board is connected to UTOR or G2T (if the mainboard has built-in RS232, please ignore this paragraph)
• Please make sure the tool board and the host are grounded!! This step is very important

Search RS232 ID

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

2. Open the WEB interface of the host computer, find in the configuration option on the left sidebar:

fluidd is: {…} , click to enter, you can find printer.cfg

mainsail is: machine, click to enter, you can find printer.cfg

3. Click printer.cfg and then click DEVICES in the top right corner

4. Click SERIAL, then refresh

fluidd refresh

mainsail refresh

5. Copy the ID, click the arrow to copy

fluidd needs to have ttyUSB, and make sure Path_by_hardware exists, this is the RS232_ID

mainsail needs to have ttyUSB, and make sure Path_by_hardware exists, this is the RS232_ID

Fill in RS232 ID

1. Close DEVICES and fill in the ID

Notes

• Please modify the configuration file:

[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>
baud: 250000
restart_method:command

Find [MCU] in fluidd

Find [MCU] in mainsail

2. Fill in the ID in 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 nozzle and heated bed thermistor pins, and save and restart.
