too small might work, but with a lot of drama and skill
fill makes the box look bigger acoustically
and breaks up standing waves
sealed boxes are pretty simple to calc and they measure close to calculated response
vented, things are much more complicated
because you have an extra filter pole that doesnt usually mirror calculations, and box size still matters
cool yeah
thats what id do if i had time and motivation
minidsp or something
most tweeters are sealed with their own tuned cavities
so you just cut a hole and pop em in
but little midrange type drivers need to be in their own cavity really
a lot of speakers, its not done, and because the low compliance (high stiffness) of the mid range vs the bass driver, it kind of works
but not really

but this all depends on the level of precision you are going for
so like, basic machine tool wisdom, outcomes depend on your particular machine, the cutting tool used, and the specific job
your outcomes will get better the more you learn about these things
plexi can be complicated because thermal issues are big problem
you typically want to use coolant
and its going to be messy
would be lucky if air was enough and itll still be messy
typically you want less flutes for chip clearing, high feed rate to keep an area from getting hot, and low spindle speed for tool life and less heat
that machine looks neat for speakers
mine is too small really
there is never a little too large if you have the space and can afford it
too large works

like, if you can rapid at whatever, but it locks up when you kind of push on an axis assembly with a finger, its prob not going to be great for cuts
try a lot of different speeds, combinations of axis movements, make sure there arent weird resonance issues
i think a lot of customers buy these type of things and then dont do much with them
sure, thats pretty logical
basically try a lot of different cuts on non critical work
well, typically something as wide as practical
which depends a lot on your tool holder and machine rigidity
maybe a little fly cutter, but probably just the biggest flat endmill or square router big you can hold
smaller bits will have better surface finish, but this is a function of how perpendicular the spindle is and how rigid, and how hard you are pushing
if its not trammed correct and you use a large bit, there will be steps between passes
if your work is small compared to the passes, it can cause squareness issues

you can use the livecd at first, so you dont even really have to install to set stuff up
well, probably you can take the stepper config and tweak it
probably thats what almost everyone does anyway, with stepper cnc
basically you want to know steps per unit and axis limits, and accel and max speed you can figure out experimentally or with some physics
right those are big head starts
but you prob want to do a lot of testing and see if their numbers are realistic for reliability, or you need to be more conservative

jero32: not much
book plus laundromat plus groceries
maybe, my setup is really close to default stepper setup and ive used same config for close to decade
id like to know about setting up arbitrary systems for scripted control, but dont see me taking the time for that for months at least
id be interested in what youre doing, and def check in with #linuxcnc on freenode, lots of long time users, devs lurk there
those docs should help a lot
look into motherboards with parport headers
and you can get a little dongle plate to plug into it
