Ajmer Thanks so much. It worked. I should have known, but I think frustration got in the way of thought. Cheers -B

Here is the curve I'm trying to cut. I think real simple, must be operator error. CURVE.MCX-7

I tried, tool geometry went berserk. tried left and right tool offset with each attempt.

If this topic has already been discussed, I apologize. I am having fits trying to cut a partial sphere on a part in 440c . I do not want to start the cut from the center going out, ( that is all I have succeeded with so far. ) I want to cut from OD to center line using a standard turning tool. this is on a Haas TL2. Maybe I'm dumb or just missing something in my definitions. time is $ and I have spent way too long trying to figure this out. I can always manually program moves, but that defeats the purpose of having a CAM system. I would rather learn what I'm missing. thanks

Jay and Colin, thanks for the feedback I did turn off the FIFO button as you indicated. I have gone through all the known places I can adjust communications parameters, (the control panel in windows, the settings menu and machine definition in MC and the software that selects the file to transfer.) I also rebooted the PC to be sure the changes were in fact made. I still can't get it to do anything more than say "loading" on my MiniMill and a rapidly popped up window in MC that say "transfer complete" Any other ideas?

I'm using MC X7 with the built in editor and communications software. I've searched for other communication software, but my understanding is that Hyperterminal is no longer provided with Windows 7 and the web pages that offer a replacement all seem to want to load a bunch of other &^%&^% On the other response...Sorry for my ignorance, but what are FIFO buffers? I will look into it next time I'm in front of the computer.

If you looked at my post I indicated a laptop running XP..It is a dell and has served me extremely well since 05. I was not able to find a suitable replacement, so I have gone with a small footprint PC.

I have recently upgraded from a laptop running XP to a PC running Windows 7. The problem I'm having is that I can not get my files to down load via serial port to my MiniMill. I get the Mini to say "loading" but no lines or file ever show up. On the PC's end it says sent, but I know by how fast it does it that nothing was sent ( running at 9600). I have repeatedly checked com1 settings to be sure everything matches. I even re-hooked up the old laptop to be sure the cable still worked and I sent over a file without a hitch. So, I'm hoping that someone out there might have had a similar issue and can give me some insight as to a solution to this. My 8hrs plus trying to resolve this is driving me crazy thanks
