Mystery holes using the drilling tool

upper end panel 31 75.crv
(139 KiB) Downloaded 167 times
A newbie here having trouble figuring out how a few stray holes are getting drilled in my tool paths. I am just now starting out in CNC and have the trial version of Cut2D pro. I have been through about half of the videos and have searched the forum and not found anything remotely like this so I need some help please.

What I am wanting to do is set up a CNC for cutting out cabinet parts. Generic parts mostly like end panels. The problem is that when I generate the tool paths extra drilled holes show up. In the examples attached there are around six extra holes, each in the exact same place it appears, on an end panel that I made separately and loaded, then cloned it to fill the full sheet. Obviously the mistake is in the original end panel and when cloned it carries forward. I tried making a new end panel being very careful with the cloning feature. The new one has that dang hole there too. The weird thing is that the hole shows up in the 3D view and on the tool path. There is nothing to select in the drawing section. The hole appears on all six panels and at the top left panel, around 306 X and 1950 Y.

So I gave up and made an upper end panel. Made the material one mm larger than the actual part, set the system holes ( for shelve pins and hinges), and ran a dado in the back for the cabinet back. The dado tool path looks okay but when you look at the drill tool path there is an extra hole in the middle of the dado.

Any ideas on what is causing this? It doesn't appear possible to click on the rogue holes to delete them.

Appreciate any input.

On the other end panel, the extra hole appears in the dado at X 283 and Y 409

Hello,

As you are using a trial version, only you and Vectric can open the file.

Post some screenshots so we better understand your problem. Please explain how you "cloned" the panel and the different steps, as clone is not a vectric command AFAIK.

Did you recalculate the toolpath after the operations you made?
Best regards

If it's on the 3D view and toolpath view and there are no vectors at those positions then all it can be is an out of date toolpath. Recalculate all the toolpaths and/or check them off one by one until you see which one is the culprit.

The first picture shows the dado selected and the extra drill vector about the center of the dado vertically.

I think I posted two copies of the first pic.

The third picture shows the 3d view and red drilling tool path. Notice the angle where the tool diverts over to the dado.

The fourth pic shows the dado tool tool path. As does the fifth picture.

These two photos are just closeup pics of the same dado with the extra drilled hole.

Next is the full sheet with six separate identical panels. There is a small waste strip at the top. About the center of each panel is a dang hole drilled that shouldn't be there.

The feature used was "array copy", I was lazy and called it cloning.

Here is the single panel that I made in another file and imported into the six in one sheet file.

Note the weird tool paths at the top of the picture. When you zoom in nothing is visible in 2d or 3d view.

Obviously the problem is in the original set of vectors, the single panel file.

I deleted the drill tool path and regenerated it. The top weird holes are gone but that center hole that ought not be there remains.

And that error message was generated, five extra vectors.

I did notice that the extra hole has now disappeared in the 2d view but remains in the 3d view.

Use the Vector Validator tool (The blue tick icon) to examine the vectors and then correct/remove any faulty vectors followed by recalculating the toolpaths.

+1

You also need organizing your work. I noticed you are manually selecting the vectors. See in the manual (Vectric manuals and video tutorials are excellent) how layers can very efficiently used for automatic selection of vectors for toolpaths.

Don't forget to recalculate the toolpaths after you modify your design. You'll also have to regenerate the 3D preview. The 3D toolpath preview is not dynamically linked to the toolpath calculation. Think of it as if you actually machine the part. If you modify a toolpath, you won't see its effects until you run it and if you already run its previous version, this previous cut is still here.

Hello algerhart,

The drilling toolpath will drill a hole at the center of any closed vector that you select for the toolpath.

The reason that you see a drill hole at the center of your dado rails, is that you have selected
the dado rails along with the circles that you do wish drilled,
You will need to deselect the rectangles from the selection and re-calculate the toolpath.

If you have "mystery" holes off the material, then there are selected vectors at those locations too.

To delete any vectors that you have off the material, type Ctrl + A to select all of the vectors within the job.
(You will see all of the vectors colored magenta).

Hold down the shift key and whilst holding down the left mouse button, drag a box over the material.
(You will see the vectors on the within the box that you drag over the material change color to black,
but any vectors outside the box will remain magenta).

Press the delete button, to delete the vectors that are still selected (magenta).

Re-calculate your toolpath.

I hope that this helps.


Cheers,

Mark.

You mean it works like in the manual? :oops:

As I always had carefully organised vectors in my project, I didn't notice and remembered this one. Thanks Mark!

(as I wrtote, very good documentation…)
