print layot 6.0 to Wegstr cnc

Post by Dande »

Hello,

print layout export to isolation milling
C1 print engraving and C2 for drill holes.
then HPGL to DXF Converter.
then use Cut2 Desctop for 2D profile toolpath and then also one for drilling.

With my cnc Wegstr mills the orbits correctly and then returns to XYZ to zero.

after the drill is set and insert the text to drill, do not drill the holes in the center of the drill holes.
what am I doing wrong???

How far off are they? The drilling toolpath takes the centre point of the vector so if the vector is slightly oval rather than round it may not drill where you expect.

If you could attach the Cut2D file or the DXF file then it would be easier to say where the issue is.

I use Cut2D desktop.
with this you can also follow how it went.

Looks ok to me as far as the Cut2D side of things goes. There is a discrepancy between your drill points and the lines which I presume are visual markers but that's in 100ths of a millimetre so won't effect anything.

Out of interest why have you done it as two separate files? It could all be done in one with two toolpaths which would cut down the possibility of errors from maintaining two files.

When you change tools are you setting the Z depth only and not touching the XY zero? It's only the Z that needs to be set.

Answer your question

Tried but shows more drill holes.

Does the Sprint layout start saying I'm doing something wrong, I've tried everything.
It would be nice to take a look at my design and maybe you'll find where it's wrong.
Thanks in advance,
Kind regards,

Here's a new file that I've created from the two separate ones. All the holes appear to be in the right place (as they were with the original ones) but it's easier to keep track of things with one file as you can preview it all together.

Everything appears to be fine at the Cut2D end of things from what I can see so I would suspect a problem at the machine end of things.

Either the XY zero is being lost between tool/file changes or the machine is losing steps when doing the drilling toolpath but that would seem unlikely as all the movement under pressure is in the Z direction.

All those extra holes in the preview image above might be the result of little tiny vectors from the layout program. For example in the original files posted if you zoom in on each circular pad (or even the rectangular pads) you will see a very tiny line.

Adrian,
With your help, the holes will be drilled in the center.
Thank you.

Adzo,

Can this be removed or do I have to create a new layout in the future ???

It's my first printed circuit board that I made for CNC machining. all is new to me.

The little lines won't matter as they are open vectors and the drilling toolpath ignores them, it only uses closed vectors. You can clear them up by using the Select Vectors menu or right click option to select Open vectors and then delete or move them to a new layer. I deleted them from the file I created.

How does this actually work to remove those annoying excess drill holes.
Cascading explanation would give me more chance to understand.

Do I need to change anything in Sprint layout first?

I don't know how you were getting those extra holes. They weren't in the files you provided and I didn't get them when I created the combined file.

As I say it won't be caused by those little lines as the drilling toolpath doesn't work with open vectors so it would ignore them.

In one of the previous post you mentioned that I just need to make a DXF.

My second design is a drama.

I'd like to fix it myself but don't know where to start.
If I have to post every design here and ask to fix it, it won't be pleasant in the long run.

You haven't any defined all the vectors for where the holes go so when you create the drilling toolpath it's using the vectors for the tracks and drilling in the centre of those.

Go back to the file I created for you and look at the layers. I created a separate layer for the tracks and a separate layer for the pads. To get the holes in the right places you need to have vectors like that as you did originally. I didn't create any of that it was all in your original file.

Ideally you should use automatic layer to toolpath assignment as I did to make things easier but if you do it manually you must make sure that you don't have any tracks selected when creating the drilling toolpath or you will get odd holes.

Small question...
use your Sprint layout 0.6
i would like to leave from this software because i think i make mistakes there.
