Hi All,

I have First MCV600 CNC vertical machining center.Fanuc 18 m used one.
I did RS232 connection between PC and CNC.
I have no problem to download or upload programms.
Especially I have problem about connection speed.
The CNC memory is not enough.Thats why I try to do machining 3D surfaces at the remote mode.But during the program transfering the transfer speed could not to catch the CNC speed.Thats why the machine doing that small pauses.This pauses make some bad surface quality.

How can I improve my connection speed.
Thanks in advance.

You have probably tried this already but have you thought about using a RS485 connection which is a lot faster than RS232, I think. See this link. You can get USB to RS485 adapters as well.

I have encountered this in the past. If you are surfacing with your program in mem mode does your machine hesitate? If so do you have a high speed machining option on your control ?

this should help, set parameter 100#3=1.
ND3 In DNC operation, a program is:
0 : Read block by block. (A DC3 code is output for each block.)
1 : Read continuously until the buffer becomes full. (A DC3 code is
output when the buffer becomes full.)

what are your current com's settings ?

are you doing surface machining ?
i found it use-full to also to improve the program, by filtering, to replace short consecutive lines into arc's where possible. this makes a large dent into the program size.
