    Communicating with Gerber Saber 408

    Hi Everyone,

    I've been tasked with bringing our old Gerber 408 into the modern age by converting it to accept G-Code posted from Mastercam 2017 but I've hit a snag. From my understanding, the Gerber normally functions as a plotter/printer, not a typical CNC router. I've gotten as far as posting a test program with a Gerber post supplied by our Mastercam dealer, but cannot send the program over to the Gerber. We uses CISCOEdit to send all out G-Code to our other machine, a 1999 Anderson EXXACT DUO, but I don't think it's possible to do it in the same manner for the Gerber. CISCOEdit transmits one line at a time, but I believe the file needs to be send as a whole entity for the Gerber to receive it. I'm currently connected via Serial port although I can't say with confidence if my settings are correct.

    Any guidance would be much appreciated.

    Thanks,

    Tanner.

    Just going to update this in case anybody else runs into the same problem I was having.

    CIMCOEdit will transmit to the Gerber, it was just a matter of getting the settings right.

    Stop bits: 1
    Parity: Even
    Baud: 9600
    Data bits: 8

    Here's some sample code for anyone that tries to get a post working. This code cuts a perfect circle, a rectangle with square corners, and a square with a radius. It works decently well, although it does dwell momentarily at the beginning of the circle.

    Code:
    %
    (NEW MCAM GERBER TEST.NC)
    (TOOL -  1 |   1/2 STRAIGHT BIT             | DIA. - 0.5000)

    Hey Tanner
    What post processor are you using to get g-code?
    regards
    Marcus
