4-axis 3D printer control board

Control board parameters:
Power supply voltage range: 12V 
Maximum current withstand: 15A
External driver:
Supported firmware: Marlin, GRblesp32
USB to serial chip: CH340C
 
Update date: 2024.8.3
Good news:
Soldered successfully
and can light up. Configure Marlin firmware
, add WP control board
, create and configure pin assignments,
configure ESP32 environment
, add pin configuration file path
, modify to your own board.
Okay,
let's compile and see.
Compilation successful. Let's
burn it in and see.
Bad news:
Cannot burn.
After inspection, the wire on the boot0 pin was too thin. Added a jumper wire and solved it. The PCB project has been thickened. See
the picture above .
Okay, no major problems. I'll test the others when the motor arrives.
The screen lights up, no problem.
Update date: 8.12
Hmm, black looks better .
Retested, burning and motor are no problem. Hmm, I won't test the screen. See the video. Modified the fan interface. The first and second versions were reversed.
There are comments about serial port screen issues. I personally tested it and found that serial port 2 cannot be used. Firmware compilation error. The next version will be fixed.
I'll test the 5-axis when I have time.
Okay, stay tuned for my next update. The next update will add an 8-axis system and the grublesp32 firmware.
Please leave a comment if you have any suggestions, and thank you for watching.
