If you want flush text, then print it face down. do the lettering in
white then change to black for the rest of the lid. Probably two g-code
files, keep the heated bed on between filament change. one layer may be
enough.

The solution might be to decide how flush is “flush enough.” One or
two millimeters might get it, but I don’t know the application that
Terry is working on.

Another option might be to print black on top of white. Use a white
base layer and then a millimeter or two of black on top. (However many
layers you need to get good coverage.) The letters would cut out of
the black to allow the white to show through. You could then either
leave it alone or use a clear filler if having it flush was a
requirement. I’m guessing a clear filler would be less troublesome
than white.

     I have used this often and works well.

         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.

Thanks Ray.

G-code files? As a novice I was hoping for a very simple way to:

Code my Surface object in OpenSCAD
Code my Text object
Union or difference
Add some clever code, so that after slicing in Cura the print would stop, I would change filament, taking care not to move the partial print, and resume to finish it.

Over naive I guess ;-)

But I’m surprised that what I’d have thought a commonplace requirement (printing text in a different colour to its background surface, with a single extruder) is not the no-brainer I’d expected.

I have done this in the past simply by noting at what layer I need to
pause the print and manually pausing the printer, swapping filament
colors, and then resuming. It is a little time consuming, but it works
fine.

If you use PrusaSlicer, the ability to insert a Pause is built into the
slicer:

     When you are slicing, add this script:

     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.

         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.

I have done this in the past simply by noting at what layer I need to pause the print and manually pausing the printer, swapping filament colors, and then resuming. It is a little time consuming, but it works fine. If you use PrusaSlicer, the ability to insert a Pause is built into the slicer: https://help.prusa3d.com/en/article/insert-pause-or-custom-g-code-at-layer_120490 On 11/26/2021 6:02 PM, terrypingm@gmail.com wrote: > Thanks Ray. > > G-code files?

Terry, It is even more simple than you say

code surface object in openscad

2)code the text object

difference text from object
comment out the text object, render and save main object as stl

5)comment out main object - uncomment text, render and save text as stl

load each stl into your slicer to produce two g-code files.
print the text g-code file
keep the bed and nozzle temperature on
change filament and purge old filament, print the second g-code file.
No clever code required.

G-code files? As a novice I was hoping for a very simple way to:

Code my Surface object in OpenSCAD
Code my Text object
Union or difference
Add some clever code, so that after slicing in Cura the print would
stop, I would change filament, taking care not to move the partial
print, and resume to finish it.

Over naive I guess ;-)

But I’m surprised that what I’d have thought a commonplace requirement
(printing text in a different colour to its background surface, with a
single extruder) is not the no-brainer I’d expected.

Another option might be to print black on top of white. Use a white
base layer and then a millimeter or two of black on top. (However
many layers you need to get good coverage.) The letters would cut
out of the black to allow the white to show through. You could then
either leave it alone or use a clear filler if having it flush was a
requirement. I’m guessing a clear filler would be less troublesome
than white.

Here is an example where I did almost the exact thing you are talking about except that I didn’t make the text flush, but I could have. (I think I have other examples where I kept the interior color flush with the surface.) It follows your first three steps below. Letting the text protrude a bit actually makes life a bit easier for OoenSCAD. Step 4 is to bring the two stl or 3mf files into Cura, select the proper extruder for each object, and merge the objects. Given that the text isn’t exactly flush with the background this could be done with a single extruder using the techniques described earlier. I would probably be unwilling to do it that way more than once. Dual extruders are in that category of things that seem unnecessary until you have a need for them.
