I have a delta 20 on a journeyman and have been able to load and run many programs succesfully, but I now need to iron out my "handshake" issue. I have ordered the rs232 cable I was previously advised in earlier post but no mattter what I cannot get the flow to pause when the storage is full.I can slow the baud rate down to 600 and wont let it overflow but then I aill get into the complex moves and it is loading too slow. I have tried many different settings and think that thee machine is not sending the signal to laptop. I tryed to force the handshake with using the graphics and dialing down the feed but it continues to flow info. I cannot get a program to " record" at all. I use a cimco program to feed and have played with all the settings. One thing I was explaning to Dynapath that they thought was odd is how I cannot start the control box if it is atttched to the laptop. The screen will stay blank, also when I set the flow conrol to " software" it will immidiately shut down my laptop and I have to reboot the laptop. I have a good grounding rod, it works flawlessly with every other aspect, I am just sick of the "buffer imput error" when I do comlex programs causing me to do way too much babysitting. IN the manual it talks about crossing the RTS and CTS lines but im am not sure about this. I set the cimco flow control to hardware and when I start the mill just sits an waits for a signal that it never begains.Then in the hardware flow type settings I choose "RTS/CTS+DTR/DSR" and it runs but it still overloads the buffer. Any solutions for this will be greatly appreciated, I wish there is a simple affordible to increace the size of memory, I find it frusterating that it will only hold about 2000 lines of code! I know this seems garbled, but I have had to peice all the know how to run this machine from this site as it not exactly up to date cutting edge tech, but it cuts like a brandnew machine, after reading other posts I enjoy this problem, It could be much worse!
