On Release 1.3.2.

Fixed previous bugs. Always software don't take into account "A" values. only x,y,z are supported, at the moment.

On Release 1.3.1 .
Erisk, there may be a minor error in loop calculation – the estimator appears to be 1 iteration short for loops. For instance, an M99P8 means 8 repeats AFTER the 1st run-through, so there are actually 9 passes through a routine, not 8. I don't have good program to confirm the validity of I, J, P, Q, and R values, which are always incremental regardless of the G90 or G91 assignment of X, Y, Z, A for G2, G3, G12, G13, G81, G82, G83, G85 (MAXNC website claims G85 support). Also, I cannot check A axis support. Otherwise, nothing pops out. Good job! Charles Hixon

On Release 1.3.0 .
Program seems to function on my WinXP without hangups. I'm not a programmer, but suspect there are errors in the estimation. Here is an example output:

processed 5841 lines (whole file)  Total time for machining: 0:47:2,349; (H:M:S,ms)  Max coord: X:4.375 Y:3.300 Z:1.000  Min coord: X:-5.7675 Y:-3.0180 Z:7.4100  WARNING: encountered lines with these unknownGCodes: G: 90; G: 80; G: 65; G: 40; 

The errors in this program may include: Total machining time takes me more than one hour, although I haven't timed it beyond that point, so it may be my dwaddling around with M6, which I haven't timed. I'm wondering if it is missing my M99s, or if it lists unknown M codes.

My actual Max coord: X:2.375 Y:1.875 Z:0.0625 My actual Min coord: X:-2.375 Y:-1.875 Z:-0.500 

Since it doesn't recognize G: 90; G: 80; G: 65; G: 40;, it may not be recognizing my changes from absolute/incremental commands. Since these also change in my loops, the program may be "walking" away with my origin. Apparently it is recognizing my G92s The results (coordinates) may also be slightly off due to a nonrecognition of cancelled drill cycles, cancelled tool radius compensation, and and cancelled continuous contouring, which are reinstated numerous times in the program. However, to get this far with this type of program and distribution is quite a feat anyway!

After asking, I followed the link and saw it listed as WinXX compatible. It's running fine on my N4.0 machine. I run under Ahha, and it doesn't seem to like some of the code, but one program I processed through it that had pretty much straight forward G-code, yielded a time that as I recall (from about 14 months ago) was very close to the actual run time. Nice job, and thanks for making this available! Jon
