Linuxcnc hotspot on raspberry pi

Hello did anyone tried to set up a hotspot on raspberry pi to connect remotely? 

No and if you want to you're on your own. Totally beyond the scope of this forum.
And not a good idea for too many reasons.

Question should be
How to set a hotspot on Linux?
Any Linux distro that uses network manager = easy, it goe something like:
-right click on the network icon located up or down on the right side close to the clock
-choose "edit connections"
-double click on the wifi connection
-go to "Wi-Fi" tab
-select "hotspot" from the drop down menu and add info as neede like BSSID etc
-click save
-close
left click on network manager and select the wifi network to reconnect
done.

That would work if network manager was the method used to manage the interfaces and network-manager-gnome was installed. But that's not the way the images are built.
And honestly if you don't setup a firewall as well.....
