when i transfer a program (this program creat by power mill & send to the machine by cimco edit ) to the memory & execute this program from memory i dont have any problem & the xyz axis run very good &smooth & countiuse but when i want to run this program from pc by direct connection (dnc mode) yhe xyz axis dont run smooth & i have a step-by-step move (like this -----) two program are same and all setting in cnc are also same
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.
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.
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.
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,
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.
