Dummy has problem with a file

Post by Kimon »

Ok I am jut a simple minded sign guy but... Could you guys take a look at this file for me? It's a mod of one of Warrens KD Chair, this one is a doubble chair with a table between them.

For some resaon it does not cut correctly the joints are not profiling on the outside so they end up being the wrong size to fit together.

What's wrong exactly, what doesn't fit correctly? Is it a specific area?

It looks ok to me. It's not something silly like you've setting to use a .25 endmill but you're using a .5 on the machine? I've done that number once.
Take it easy.

Lockeyone,
If Kimon is like me, they are to mark screws for holddown. I always drill a small hole where I'm going to place a screw so I won't hit it.

When I do the preview the notches do look alittle funny. Have you actually tried to cut the file? I assume the width of the notches are designed for 18 mm ply?

Couple of spots that could use some clean up. Double lines etc. Check each of the pieces for the same. I think the feet all have the same. This is what I saw at first glance.

Hehehe, no I started the file and it didn't cut correctly so I went on to some other production work. Cutting widgets for a plastic company, not sure what they are for but they need lots of them. I should be finished by this weekend and will be able to go back to playing soon. First I gotta fix the file.

Yes those random drilled holes are for material holdown.

Kimon,

Sorry not to have come back to you sooner, been on holiday since the 6th.

Lockeyone has picked up a few points where you now have overlaps, these need to be modified. Also you seem to have lost the rads at the base of the legs.

The problem with the incorrect fit for the joints is an easy one to rectify.
You have a rectangle selected 96 x 48 inches, in profile 1. Just delete this and calculate profile 1 again.

Cheers,
Warren.

Yep that was my problem, deleted the rectangle and re-calculated the toolpath for profile 1. File cut great, I will assemble it tomorrow and post pics. Thanks very much something so simple I just couldn't see it.

So why did the rectrangle mess with the toolpath? Or why deleting the rectangle fixed the issue? Curious.

Because the toolpath was set to cut outside the vector, with the rectangle selected the toolpath cut outside the rectangle but inside the actual vectors.
