Have the person with the lathe use it to externally thread a length of metal so
it will screw into something he already has to screw onto the spindle. Then he
can ship that to you to use for a fit testing piece.

Hi Andy,
F-engrave might just fit the bill for simple sign work like this. Thanks for

Thanks. I’ll take it for a spin.

Yes, for this project I was given the DXF files.
Aside from that, I haven’t had much luck working with text in Fusion 360. The
text feature appears to be an afterthought; there is no way to fix alignment of
text and certain fonts refuse to work altogether. What I’ve been doing is
designing

There are lots of tools. They tend to be expensive and very specific.
For example: https://www.ebay.co.uk/itm/392769109694
Which probably cost over £1000

I forgot that I had that in the workshop. Though I am not sure that I

That's cool Andy. I have done similar all the time. For external threads
I bought a cheap 3wire set that has a chart with it and gives me all the
calculations I need to use. It's just one simple formula and it tells me
the closest wire size I should be using.
For internal threads I usually use
Have you looked at F-engrave? It's an engraving and V-carving app for
Linux. scorchworks.com.

I've been using FreeCAD and I do like it quite a bit. It's very
powerful. The two downsides I see:
1) It's currently at version 0.19. It's not polished software. It's
definitely usable as is, but I save my work often. It does crash
occasionally, usually when I do something stupid but
Most likely he is being given artwork from the artist in the form of DXF files
that he must turn into machine files that cut out signs.
Other free Linux based options might be Inkscape with G-code Tools, or Freecad.
But both of them might be more painful to learn/use than what you're doing

I forgot to mention I think there’s a way to alter the startup defaults.
According to the link below, editing "imperial_startup.ngc" can be set to your
desired parameters, but if you have a reason to change the P value (like using
a different value for roughing) it won’t return to that value.
If you want a more simple workflow can't you stay 100% in Fusion360? I'm
trying to figure out why you'd need a .dxf file.

Maybe noise on the keyboard
There does not seem to be any delay in the matrix_kb component:

Also even with default sserial error management you could only have
10 servo thread cycles (10 ms with a 1 ms servo thread) of delay

I just ran into this issue (again). I did some searching and found that
LinuxCNC defaults to G64 with no P value specified as of a certain version
(2.7?). That caused some issues for me over the years, so I’d been manually

I’m using Fusion 360 in a workflow for engraving signs. This starts out as a

As an aside, if anyone has an idea for a simpler workflow (free, of course) and
one that perhaps doesn’t
Hi Andy,
great post, thanks! It all goes to show that threads are complicated. Some
of those standards were written over a period of 20 years, that is no joke.
Nothing to physically test your fit against - brave!
