Hello,
I've spent many hours to write a macro to import a .csv file but it doesn't work properly and I had no idea what went wong.
Eventually I noticed that the Lua I/O routines skipped lines that contain the german letter "ä". This letter appears in almost every line of the file because the german word for a milling tool is "Fräser". After replacing "ä" with "ä" (that's the string Mach4 use in tooltable.tls to represent "ä") everything went fine.
regards from Germany
Klaus
