Completed my Build!

[mattYogi]

Thank you very much for the detailed instructions and software. I have finally completed my build. Very happy with the results.

I had some minor challenges along the way. Sharing those and my resolutions here in case it helps anyone else.

• I had some challenges with dependent library versions. Running the following commands seem ed to help.

nvm install --lts
npm audit fix --force
npm install --force

• I also Auto Updated web pack config to be compatible with latest version

• I had to update the port.on function in led_controller.js because the data event on a serial port doesn't guarantee that you'll receive an entire message in one chunk. The message might be split into smaller fragments. I was seeing that "a" and "ck" were being received in separate chunks causing the controller to resend commands.

let buffer = ''; // Temporary buffer to store incomplete data

port.on('data', function (data) {
  // Convert data to string and append to buffer
  buffer += data.toString();
  
  // Check if the buffer contains the full message
  if (buffer.includes("ack")) {
    console.log(`Received full message: ${buffer}`);
    
    // Clear the buffer after processing the message
    buffer = '';
    
    // Handle the acknowledgment
    if (cmd_interval != null && cmd_res != null) {
      clearInterval(cmd_interval);
      cmd_interval = null;
      cmd_res.sendStatus(200);
      cmd_res = null;
    }
  }
});

• I think the link to V wheels in BoM is incorrect (seems to point to the larger wheels). I purchased these instead.

• I had some issues with magnetic interference on the WS2812 signal line. Moving this wire away from the Stepper motor wires seemed to have helped.
