Topic: Fanuc 10M - Buffer Overflow 2
|
| By: Daniel Pereira - Portugal | Posted on: Oct 15 2012 at 04:03:21 PM | Hello,
I'm trying to work in dnc mode with a Fanuc 10M but i'm having an error when I'm sending the program to the machine after about 2min. I'm unexperied!
I can send and receive programs or parameters. The machine parameters are: baund rate 9600; even; 1 stop bit;
I've searched in the web and they told the soluction is stting the block delay to: 300 ms
My problem is that I can't change this set to 300 ms in the easyDNC 4.7a. The option is from 10 to 200ms and "Fast".
Someone can help me?

But 300ms block delay would be very slow. What happens if you set 200?
If you need a block delay as high as 300 then you'd probably be better going down to a lower baud rate and then use a smaller block delay.
But first thing to do is disable Windows FIFO.
Control panel > system> hardware > device manager. Select the com port and go to advanced. You'll see sliders that you should slide all the way to the left and then uncheck the box to disable FIFO.
Next thing is the baud rate. Start quite slow at 2400 That may starve the machine even with block delay at zero/fast. Increase the baud rate to 4800 and see how that goes. Basically you want to run with the baud rate as low as possible but not so low that it causes the CNC to starve, jerk and stutter through lack of data.

We had to make some changes to the settings in the EASYDNC software settings. They were as follows: Mode-Standard, Com-Which ever one you have selected, Data rate-1200, FlowControl-Xon/Xoff, Data Bits-7, Stop Bits-1, Parity-Even, Block End-CRLF, Block Delay-10 and check Force CR/LF.
The key one was the block delay. I have a couple fanuc 11M machines and the block delay is set to 5, but the fanuc 10M requires a block delay of 10. I hope this helps. | |

IN fanuc 10 | |

Sounds like an error in one of the system ROM chips. I'd say you need to be calling in your local Fanuc rep. | |

baud rate = 4800
parity = even
data bits = 7
syop bits = 2
what should i do !!
please help me.
Thanks | |

Try downloading and installing RemoDNC. Then look at the answers above. | |

| By: Guest | Posted on: Jun 22 2016 at 08:04:48 PM | | Note about the FIFO change. Be sure to restart your computer. I spent a hole day trying to get my 10M controller to drip feed. After restarting my computer drip feed worked perfectly. | |
