    Fadal DNC error

    I have recently tried to do some Fusion 360 (3D adaptive ) and have been running into issues with a DNC error. I am using a Calmotion USB to DNC the program from Fusion. I first thought is was my baud rate . I was typing in CD,10 which is default for 38K baud rate, and the machine was set at 9600 . I changed all of that to match the 38K baud rate, and still have errors. Is it because the Fadal can’t process the short fast moves?
    I have seen a few replies on other posts in this forum that’s says the USB has a lot of problems.

    I have never really had a problem until I started making more complex parts(not complex for a CNC mill, but more complex for our shop)

    The Fusion seems to work great.

    ...try 19,2k? and yes usb can be a problem, Calmotion may have a firmware update for your unit ...worth checking Also, is your backup Battery in new condition? I have seen that cause problems

    Are you using DNCX? I use that for my Calmotion USB from Fusion 360 and it hasn't missed a beat yet.

    Make sure you don't have the configuration file on any of your usbs. You might be reloading old parameters if you boot up with the USB inserted.

    ...just a thought about Fusion post processor.. your program does have a % on the 1st Line right? Is the Format correct from Fusion? No looping or sub program calls using DNC right?

    try testing a known good program using DNC may help set baud rate, too
    good luck,

    DNCX is a must read pg 147 of this free Fadal manual... DNCX This command operates the same as the DNC command. This command usesthe Xmodem protocol instead of the XON/XOFF protocol. The Xmodem protocolallows for long term DNC operations at higher baud rates with longercommunications cables. The Xmodem protocol sends data in packets of 128data bytes. After sending the block of data, checksum is performed. The nextpacket is sent if no error is detected.
