There are thousands of lines of code to change which would take hours and it seems that there should be a way to automate the solution to this problem. I asked this same question about 2 years ago, also with no answear at that time. It seems that by now someone would have a solution.
I can't find anywhere in Visual Mill to introduce a 4th axis movement speed. Best I can tell is that it assumes the same speed and feed of the x axis which is in inches/per minute. At 2.7 degrees/min it will take 130 minutes to travel 360 degrees just for 1 pass. The G-code will make 6 passes of the a-axis, wihch will take 13 hours. And then 2 more finishing passes.
If someone knows a way to change that in Visual Mill I would be thrilled to hear it. What about Mach-3, is there no way to change it there. What about some VB script to adjust the feed for a-axis?
Now, I can spend a few hours manually changing the G-code. But what about next time I generate code. It seems like we should be able to have this done automatically.
I cant believe that I am the only one having this problem. If I am, I sure would like to hear how the rest of you guys are doing it that is different from me.
I am extremely frustrated and need help BADLY.
