If someones interested I'd give some more information. Still this is just a quick sketch of what I did. I set the baud rate up to 115200 which allows some decent transmitting speed. If the service records a request from the machine it waits for some time and then transmitts the program from the shared folder over network to the esp and from there to the serial port of the machine.Īlthough the solution is still RS232 based, my collegues and me still have found it useful. Furthermore the server also runs a small python script to listen for requested program ids. Receiving files from your CNC is always going to be much easier. You then walk to your CNC and output the file. The Ubuntu Server (Raspbian would work too) has got a samba share for our programs. Receiving files from your CNC is extremely easy, all you have to do is click the large Receive icon or click F4 and select the name of the file you want to receive - dnc4U will then just sit there waiting for the file to come through.

Okuma does offer a software called 3DVM which will simulate your programs. Then the server transmitts the requested program to the machine. The Server waits for some time so that the user has some time to enter the program id and switch the machine into rs232 recv mode. You would enter a program id which would then be send over serial to an ESP8266 and then over network to a Server. On our Haas machine I created a Gcode Program which acts as a program request.
