What baud rate are you communicating at? What feedrate are you programming? How long are the line segments you are interpolating? Sounds like the baud rate is too low for the feedrate you have programmed.

[mostafabagheri]

feedrate is 2000mm)min and baudrate is 9600 but in meldos catalog say the max baudrate is 1240

I'm not familiar with the Meldas 310, but I'm pretty sure there is no such baud rate. 110,300,600,1200,2400,4800,9600 are all pretty standard, but 1240?

I'm also not familiar with Cimco Edit's DNC settings, but check to see if there's either "Character Send Delay", or "Line Send Delay" or anything like that that could be slowing the transmission down.

sory for this typing ignore . 1200 is true . and i can find these parameters in cimco :

delay befor each line
handshake timeout
breack after receiving character

are these useful for our problem ? and do you have any good suggest for adjust this parameter ?
do you have any good software for dnc ?


and say again tanke you for your help

Delay Before Each Line sounds like the one. If it's not already, try setting that to 0.

I'm confused... is your baud rate set to 1200 or 9600? If it's 1200, bump it up to 4800 or 9600. If it's 9600, bump it up to 19200. If your cable is good, and the handshaking is working properly, you shouldn't get overflows.

the 310 wont handle a rate higher than 9600,what is your computer?older one,sometimes this causes a dnc problem

[mostafabagheri]

i have a same problem in richmond machine , in richmond my baudrate is 9600 & in meldos machine 1200 , and i use new labtop for dnc

[hutch07]

Go to your Parameters - in/out screen and see what the handshake time out setting is. I know Mitsubishi lets you set this. Bump it up to 200 seconds to see if this helps. check out www.meau.com

I am also looking for a good up-load/download program. I can not communicate with the Mitsubishi Meldas L3. I have gotten a few characters using some stuff but nothing usefull,

[dcoupar]

mostafabagheri,

I checked the Cimco Edit V5 documentation, and the only thing I see that could slow the transmission is the Delay Before Each Line. Did you check to see if that's set that to 0 yet?

Hutch o7,
I recently aquired 2 Machning centers with Mitsu MO controls. I use Hyperterm in windows for sending/receiving files. I am running that at 19.2 and with a 50 msec. line delay, it feeds faster error free than at 9600 with no line delay.
I messed around for a while trying different settings until I got it right. If you are still having trouble let me know and I will send you the settings I use.

Better you can use micro dnc unit for transferring the program, that will save the space and accurate data transfer
