I've not yet made a print including text with my Ender 3 V2. But I'll soon need
to do so and would appreciate some advice on a few practical points from more
experienced users please.

The 10 text labels will be on the top surface of a rectangular box lid, which
has dimensions of 175 x 95 x 3 mm. Maybe a bit thicker if necessary. The labels
(like On/Off, Up, Down, etc) will be near holes made for various buttons and
switches. Each label will therefore be fairly small. I want them to appear flush
with the surface, white on my black PLA filament.

One option might be to fill with something like 'Hard As Nails' glue/filler,
wiping the surface clean before leaving the filler to set.

But ideally I'd like to do it by stopping the printer just once, changing to
white filament, and resuming (something else I've not yet tried). If I go that
route, what changes do I have to make in OpenSCAD and/or Cura, so that the stop
occurs at exactly the right place?

Would another idea be to make each label say 1 or 2 mm high and push them into
place? On reflection I suppose they could be printed as one object joined by a
thin, easily removed line?

All suggestions/tips/advice will be much appreciated.

Since you using Cura + Ender, you should be able to pause the print using a Cura supplied script.

When you are slicing, add this script:

Extensions -> Post-processing -> Modify g-code

Select "Add a script" and select "Filament Change".

Change the "Layer" value to the layer where you want to change the filament.

I have used this often and works well.

Thanks for all the help so far, much appreciated and will keep my busy
for some time.

Meanwhile, where am I going wrong with this first very simple (!) test
please. I just wanted to print a small rectangle containing two pieces
of text to:

1. Give me a feel for font size
2. Let me try filling some taped hollow text
3. See what 1 mm high embossed text looks & feels like, prior to
   trying that with white PLA..

But Cura shows that it will at best fail to print the latter, and I
can't spot why?

PrusaSlicer is happy with it.

Found that and enabled it but still the same:

Any other settings you see there that might be the culprit?

Yes, we see your attachments. The problem is that the object is tiny. Can
you scale it up in x and y by a factor of 2 or 3?

Thanks for testing. That motivated me to install PrusaSlicer and load the
STL.
Attached or here:
https://www.dropbox.com/s/7v84l70rbextg5p/Hollow3and4.stl?raw=1

But when slices and previewed I still don't see the text '#4' on the right
hand
side. It looks almost the same as in Cura. And same after trying the
'Repair'
option. Screenshot attached, or here:
https://www.dropbox.com/s/xoywpxf9o7g3xpt/Prusa-2.jpg?raw=1

So, you do see all the text? Is it possible to export PrusaSlicer
settings? If
so it would be very helpful if you could send me yours please.

Thanks for checking, that's reassuring.

Scale up the model? I want to print it at the small size I anticipate needing to
fit the 10 labels into the panel described in my initial post,

Going bold helped a bit  - worked at 140%.  You might try other fonts.

I've had to add tiny cylinders or tall cubes to individual parts of letters for the model to be accepted. The issues are different for embossed v's extruded too.

In the end, it really needs to be important for me to try that again.

Thanks for staying the course, that’s a good result, albeit intriguing. My best guess
would be something else in your settings accounts for it. Is there away for us to exchange
all settings and do a compare? Unless you can narrow it down to a few more that I’ll then
check.

I would start with the text the size you think you need for the solid
text. Then subtract larger versions of that text to make the hollow
portion until you get something that fits. I don’t have a clue how
OpenSCAD will do scaling in this case or what will happen with the
inner parts the lettering.
