Thanks, Steve! I apologize for taking so long to reply, but your suggestion worked perfectly.

Crazy, Yes, I've seen what you mean several times now. I am in the process of altering a version of the new MPLFAN to my liking, but I am learning as I go and I still have parts to program in the meantime. So, for the time being, I am forced to fool with the same old stuff for a while. Thank you for the recommendation.

Prosin Molds, I use R's because that is what all of the machinists here are used to seeing, and it makes it easier to read the program at a glance. I always break my arcs @ 90degrees as a habit from my days of programming with a calculator. Colin / Greg, I have checked all of the paths and they are correct. I am using the machine definition to alter the control def. Dragracer1951 I found a post in my system (recent MPLFAN) that would output the R like it is supposed to. The problem post is an old V9 post that has been altered and updated several times. I compared the arc settings in this with my problem post, and they are the same. However, I had a look at the 'parc' postblock, and discovered that they were very different. I copied and pasted this block from the good post to the problem, and now the problem post seems to be outputting as expected!!! Thanks for all of the suggestions!

Some of it was read-only. I changed this and opened the control definition and saved it, but it made no change to the posted output.

Now, it's not working again. I guess I am going to just have to pay attention to when this occurs.

This day as made me want to go back to programming by hand. I have been using MCX2 (initial release) since it came out. I am a lathe programmer, so I am using the lathe product. My employer recently bought me a new computer, and MCX2 MR2 was loaded into it for me. I have been using MR2 for about a week with only one minor problem, but today a major problem showed up out of nowhere. Suddenly, I started getting I/K output on my arc moves instead of R's. So I edited the control definition to "Radius" (I don't know how it got changed from this in the first place), but the output continued to be I/K. I played around with absolute the other arc settings to see if changes occurred in the output, and some did, but I never got R's. I went back to a file that I used last week (the output was OK) and it still outputs R's. However, in my investigations since, I have discovered that any new file, regardless of machine definition or postprocessor WILL NOT output R's even if I change the control definition settings. Any ideas? PLEASE HELP. Thanks.

Thanks for all of the suggestions. I did not even try to change any of the settings for my mouse, but today the zooming with the mouse wheel worked just fine. We've been having problems communicating with our network connections lately. Maybe that's why.

No, it is XP. When I get a chance, I will look further into MLS's suggestion above. I think that may be the problem.

Thanks for the info Ray H., but I just tried all of the possible combinations. None of them worked. Any other ideas?

I have been using MCX2 (initial release) since it came out and have gotten quite fond of the dynamic zooming using the mouse wheel. It anchored the center of the zoom @ the current mouse location, and zoomed in/out depending on the direction that the wheel was rolled. My employer recently bought me a new computer, and MCX2 MR2 was loaded into it for me. I cannot seem to get MR2 to perform this zooming with the mouse wheel. Any ideas? Thanks.
