I was going to say that there's no way the Run from here can work without going back. :)

g42 prob.JPG


Is this a bug???


I created a simple part with my plugin, I used G42 for tool compensation on first cut for a square than code gives a G40 and continues with pocketing a circle and a canned cycle for 4 holes in each corner.

If I remove the G42 the code runs fine but with no tool compensation for square.
if I remove the canned cycle the code runs fine.
if I use absolute mode for canned cycle code runs fine.

If I scroll through the code it shows the way I expected, but running the code the canned cycle follows glitch path.

The active line shows G40 model at canned cycle.

The picture you show looks different from what I see, as I see two comped toolpaths in yours, but I only see one?
But yes, the drilling goes out into space.

You have a formatting issue in there on this line, which should be two lines.

Thanks Gerry, yes that's should be the next line of code and was when originally generated. I was continually editing code when trying to determine where the problem was.

Hi Dezsoe, I was doing a lot of copy and pasting for reasons I just previously posted and to shorten code due to multiple passes.
I just generated again untouched with same results as pic I posted.

That's something in the generator. Now in the full code there are 4 lines with the same errors. Here is a copy of the last few lines of the file (see the first line):

And if you run it line by line, it draws good, but runs another way...
