Hi Gene,
I have been playing with a Creality cr-10 mini for a couple of years.
When I first bought it, I wasn't sure what I would use it for, but I
wanted to explore the technology. You are in for a fun ride but it takes
patience and a little experimenting when things go wrong.
Using linux, I use the following tools:
stl gcode usb serial
OPENSCAD --> CURA --> REPETIERHOST --> 3D printer
design cam stream gcode to machine
openscad is like a little scripting language where you describe your
part geometry.
openscad exports stl files (triangular surface models)
cura takes the stl file and converts it to gcode that moves the
printhead around and controls the plastic extrusion nozzle.
You can put the gcode file on an sd card and plug it into the printer or
I use repetier host as a gui that draws pretty pictures as it streams
the gcode to the printer. The gcode files are quite large as everything
is repeated a lot as the approx 0.2mm layers of plastic are piled up.
some of the little gadgets I have designed for my projects:

I also have used the overture filament... seems to do the trick!
I dont use the hot plate cover.. I used to print on the glass bed, but
recently I have been using 2" wide blue painters tape on the bed as it
does tend to grip the objects well and can be replaced if it gets
damaged when prying off a part. It leaves a nice texture on the bottom
of the part.
The biggest challenge in getting a print to work is getting the first
layer printed and stuck to the base material. Mostly this involves
getting the bed height adjusted properly so the first layer sticks
evenly. (bed leveling and height adjustment). There are lots of software
adjustments in cura, but if you select a PLA profile, the defaults will
be close to getting you a good print.... youtube is quite helpful if you
run into issues.
Have fun
cheers
