Topic: 15_M FANUC CONTROL
|
| By: COACHJCSMILES | Posted on: Nov 14 2007 at 06:29:07 PM | :cry:
Im trying to drip feed with software, getting alot of pause and jerks in the motion of machine. Any ideas on how to get machine running smoother would be greatly appriciated.
Im only using the trial software but if it works out will be purchasing it for my company.
Im cutting a large Vacum fixture with alot of 3d shape on it.
Thanks

First thing to try is easyDnc`s block delay/size settings this will increase the data flow just a little which is all I think it needs.
Take a look in easyDnc`s setup and you`ll see a couple of settings.
Block End
BlockDelay
and, depending on the version, block size.
Try reducing the block delay. There`s a setting of `Fast`. try that.
If that doesn`t help then you`ll need to increase the baud rate.
Parameters #5112,#5122,#5132 in the fanuc are the baud rate.
This will contain values like 8,9,10 etc. 9 would usually mean a speed of 2400. 10=4800 and 11=9600
Change easyDnc to match and give that a try.
If you make a large change in the baud rate then you may experience buffer overflow in the fanuc. if that happens you`ll need to reintroduce the block delays (if you removed them)
Basically you can adjust easyDnc`s block settings to make small adjustments. Change the baud rate to make big adjustments. | |
| By: coachjcsmiles | Posted on: Nov 15 2007 at 05:45:43 PM | :( the setings you told me about worked great for about ten minutes and then it got a buffer overflow alarm. I tried to lower the baud rate but that also caused a bufer overflow problem.
Again the settings I have on the control are as follows
5110 3
5111 2
5112 9
5120 3
5121 2
5122 9
5130 3
5131 2
5132 9
The settings on the software are as follows
Baud 2400
Flow control xon/xoff
databits 7
stopbits 2
parity even
Blockend crlf
block delay 10 but i played with it up to 100
Stepsize smooth
I also tried the fast setting on one other thing i cant remember but it didnt help. | |

It ran for about ten minutes and then gave a buffer overflow | |
| By: Support | Posted on: Nov 16 2007 at 12:56:14 PM | The first fault you mentioned was that the machine paused and jerked.
That would normally indicate that the data is being fed too slow.
The second fault you mentioned was the buffer overflow.
That would normally indicate that the data is being fed to fast (or that flow control is not working efficiently)
Can I assume that when you had the jerky machine you didn`t get overflows and that the overflows only started happening when you altered the settings to stop the jerks ?
It might be quicker if you email me.

| By: coachjcsmiles | Posted on: Nov 16 2007 at 02:37:51 PM | the machine ran great for 5 minutes then gave a buffer overflow alarm
i tried adjusting the baud rate but that made it worse.
Any more sugestions would be great!!
I want more then anything to get this software working. Could it be my cable?
Problem in control?
Should I call Fanuc?
Thanks Again | |

I might want to send an updated version of the software. | |
