Actually, a while back when you mentioned you were going to do a half size gorilla, I had a look at the files. And came up with probably the same problem. I started a thread on it: viewtopic.php?f=100&t=1181&p=10892#p10892 You could try the old version .918, as reported to work in that thread. I have posted dos batch files to switch between versions. I never fully understood what the problem was. The new phatscript is about to come out and hopefully will fix the problems with the over lapping phlatlines. If you look at the space between the outside cut phlatline and the orginal part there should a surface (grey). If not then the gcode won't be generated there. If you look closely at the yellow phlatline, you can try and correct it manually. I tried it on a simple part and it seems to work. The tricky thing is even after you get the yellow phlatline outline correct, you still have to force it to make a surface. You can force it to do this by just drawing a line over an exsisting line. Especially, if you look in the slot of the simple shapes, you see some weird T shape thing (at the very end) which I think is the frequent cause of the problems. Don't see why they are there. It's just a regular 1/8" slot, not a sharp angle?

 

Bruce, i've had a look at your file and there seem to be a couple of problems that i've spotted so far.

Firstly there are quite a few stray lines dotted around. If you haven't already got the 'stray lines' plugin then download it from here (free) : http://www.smustard.com/script/StrayLines put it in your plugins folder and when you restart Sketchup it will show up in the Plugins drop-down menu. Choose 'label' from this menu and it will show you where all the stray lines are in the file. You can delete these if they are not needed or join them together if necessary.

The second thing i've noticed is that some of the Outside cut lines overlap. This is a common problem due to problems with the 'offset' tool in SU, The new version of the script which is due to be released very soon should prevent this happening,

It's midnight over here in the UK, so I haven't got time to look at it further tonight, but i'm sure the other guys will have it fixed for you in no time.

Si.

 

I took a quick look.It appears that some segments are on the WHITE layer, some segments are on layer0... Try moving everything to the same layer. Scott..

 

ewo, I think version 922 due to be released, I thought this weekend, will solve your problem.

I am able to get the parts to generate correct gcode, but it taking quite a bit of time for the paths to be analyzed. You will have to be patient selecting parts and marking the paths.

I did not make the tabs, but I did manage to make all of the cut paths for you...

By the way... Tim spent a lot of time on the new 922 version and the script changes he made specifically address this issue. You will notice that it takes a while for the paths to be analyzed but that is because the script is doing its job sorting out all the overlapping angles which prior to version 922 cause problems with the cutting.

The new version should be available to everyone very soon, maybe even later tonight. Attached files Monkey.skp (6.2 MB)Â gorilla.cnc (637.5 KB)Â

 

That dialog should only appear if some of the cut lines were created with an older version of phlatscript. If some of them are older then you need to upgrade before generating gcode and all grouping will be deleted in the process. Unfortunately there isn't a way around deleting the groups due to the way Sketchup stores data about the cut lines.

 

I've got to add that Tim put in an algorithm to automatically find the best path, so you don't have to regroup. Unless you want to force it to cut a certain pattern. But it looks awfully tough to try and select those parts.

 

Mark, that's a good tip. I knew about the double click, but not the triple.

I got this quick video capture of the gorilla automatic cut order, using the v922 ps:

Bruce, i'm glad you're getting this file sorted out. Just a quick note about the Stray Lines plugin... If you select everthing on the page using the select tool and then run the plugin it will label all the stray lines in one go. IIRC when I tried that last night on your original file it found nearly 40.

Let us know how the monkey comes out when you've cut it

Si.
