I downloaded and unzipped the files, then started CNCjs on Mac from command line. I'm using the Desktop App, which appears to randomize the port. The boilerplate will not connect. I ran the code with Debug on Visual Studio Code and the io.connect call returns a socket with state "connected" = false and "disconnected" = true. I also installed cncjs-shopfloor-tablet-master just to makes sure that something will connect to the App. Shopfloor-table works. Is there anything in the .cncrc file I'm supposed to include for the pendant or anything I need to do to get the code to connect?

I am installing it on Raspberry Pi 4 but no success due to old and unmanaged dependencies, this happens with keyboard pendant too as it is based on this pendant. Kindly update or guide for a workaround.

It would be good to have a pendant example that correctly reinitialized itself after a serialport:close socket event, coming from the close connection button in the UI.

I'm making use of smooth jogging and, after the connection is closed, have not been able to reinitialize the connection in the pendant in such a way that I'm able to receive serialport:read afterward. Instead I'm just doing a process.exit() and letting pm2 reinitialize it.

So, I was working on the cncjs-pendant-keyboard and I couldn't make it connect to cncjs (hadn't made any changes yet - or at least I thought so). To make sure, I tried out cncjs-pendant-boilerplate. This couldn't connect either.

So after some quality time with Wireshark, I noticed the pendants trying to connect to ::1 while cncjs was being hosted on 127.0.0.1.

I worked around this by disabling IPv6 completely on my system. I couldn't immediately find out how to force the pendant to connect to IPv4 address only.

Setup:
Raspberry Pi4
Debian GNU/Linux 11 (bullseye)
aarch64

Is there any reason the pendant mandates the serial port CNCjs connects to, instead of using whatever port is connected already?
