I'm looking for a program to essentially simulate gcode and give me a run time. I found NC Corrector, but it doesn't seem to support the Imperial measuring system (Inch). I have also found a couple different web based editors/simulators but they didn't work out. I have a hobby license for Fusion 360, but have 0 idea how to use the program and I tried to lookup if it supported it. (Doesn't look like it does) I need something free or cheap.

Thanks,

If you require software that will give cycle times for each operation I suspect that you are quoting work.
If you are quoting work you do this for a living.
If indeed this is industrial work why are you asking such questions on a hobby forum?

If you are not capable of converting simple linear dimensions between inches and millimeters you are already at a disadvantage.

I work in a smallish (13~ machine) CNC shop. I'm not really a apprentice, but have room to work up. (Seems like it anyways, not sure how far) I've been wanting/trying to get myself to a higher position for quite a long time. I've recently been looking into computer programs as well as trying to read machine manuals and learn them. (Can only do so much) I really want to learn this one machine that no one really knows how to operate, but I want to learn G code too, which is what I was using the NC Corrector.

I was also trying to figure out how much time was being wasted with the way the machine was programmed to drill. I wrote some G code in a .nc file and opened it up with NC Corrector and found it was in metric. It makes it harder to learn when the program has to be converted to a unfamiliar measurement system, when what I'm already doing is unfamiliar.

I was thinking a CNC forum would be all about CAD/CAM. (not sure if I really looked at them that much, it was a while ago) I don't really have a reason... I've been getting good help here.

I tried to build an estimator into my software at one time, but it proved fruitless. Too many variables in the real world. I don't try to optimize the G code of one off parts, but when running production I just look at the way the machine is running and manually make corrections to the G code. If the depending on how the CAM program generates the tool path it could be that you could save some time there on a drill cycle. Retract height can make a big difference as can the rapids between holes. But there are a lot of variables that you have to concider.

If you want, attach your G code file to a post (use a .txt extension, the forum software does not like .NC extensions), I'll take a look at the G code and run it in my simulator to see what it does. If it's compatible, I'll run it on my machine.
