We just updated our Mach3 from 1.84 to the newest version. Running a file that we've run 1000s of times now is give us trouble when we radius a corner
Basically the code that hangs us up is
G91 G02 X ?? Y ?? R2.0
This line would usually give us a nice 2" radius corner and now just dives into the piece
I dont remember what the exact XY coords were but the file ran for years and now is giving us grief after the update
-
IJ mode perhaps?
-
tried both settings same results
-
Mill or lathe ???

Its a mill

Post your code and your xml and I'll see if I can get it to repeat and if so see if I can find out why.

here is the g code that we have been trying to run

Bret here is the XML and Mkak posted the code. He is a colleague of mine

Try editing this Ryan and let us know how it does.

that worked but now the radius is to big so it isn't even cutting a radius into the piece ill try changing the radius size and see if that cuts what i need.
-
tried changing the radius and it did not work. but we entered the MDI mode and entered the G91G02X-0.125Y0.25R2.0 and the code worked exactly how it should have and has always worked so it has to be some thing that is throwing it off before that line of G code.
-
We were able to get this code to work how it is suppose to work but once you put it back into the Program it has the same issues as before and cuts back into the piece. Here is the G-Code that we got to work with the radius and ill give you the program it is suppose to go into.
(G-Code that the radius is working in)

(This is the program and once we put the G-Code in it no longer makes the radius it starts it and cuts back into the piece. same issues we had before)

The first line of the code that doesnt work has a typo. You have a double G in the first line. Is this a cut and paste of the code that your trying to run or a copy error?

it was a typo my fault
-
Pity. Shame it wasn't a nice and easy fix for your problem.

NOT exactly sure what you are trying to cut BUT sitting here looking at it in single step mode it appears to be going exactly where you told it to go wherever that is.
I don't see it cutting any usefull shape as it cuts BACK into itself several times
