post an image. i will convert it. you decide if it works for you. no charge to find out.
i wrote software to do it.
the a axis travel of 0.004 inches will produce one pulse for each uStep of the axis.
on my mill, that's 32000 steps/inch, so 0.004 inches makes 128 pulses (zaps of the...
i can convert it to code but will the code run your laser?
sample of how mine does:
g0 x0.23234 ;go to the next dot
a0.004 ;zap it a lot
g92 a0 ;reset the zap-0-meter...
yeah, that's a tough one, isn't it? why would anybody reply to a comment?
but now you're just being mendacious.
there was no question of whether any laser can cause damage (it's what they do,...
been there. there are better sources of information, I think - for example:

admitting and correcting is how one earns a big S tattooed on one's chest and it stands for 'sapiens'.

well... speedy- let me correct you on ... everything...
this is a 445nm blue laser diode.
it is essentially monochromatic- it has no spectrum
it is not synthesized by a crystal
there is no 808nm...
obsolete in name only because there is no shortage at all.

how many thousand would you like tomorrow?
but my question was why somebody...
" Now the board uses the MAX31855K instead of the MAX6675, so it can measure a wider temperature measurement range."
is this a joke? the extra bit is a sign bit and nobody needs to print at liquid...
i have a 2w 454nm diode laser on my taig.
see how it does on some things here:

That is a beautiful .bmp - it looks like it would convert perfectly to levels corresponding to grayscale.
I've done a lot of software to convert .bmp to g-code but most often it takes a lot of...
that looks like a good candidate for a cheap injection mold by CNC in aluminum.

this looks pretty sweet if you run turboCNC or possibly EMC.

this is the best i know for ready to go desktop machines.
i'm sure there are others somewhere, though.
i'll see if i can get a proper final divider circuit posted tonight.
i'm sleeping thru the days now and staying up at night when it's tolerable temperatures.
but i have a heap of stuff on my plate,...
i had to move computers into the bdrm so i can set up the 2 mills and 4 taig lathes i'm rigging for cnc in their own room and give the wife back a living room...lol
she allowed me to get away with...
aha!
must use same edge for clocking both ways or you can false trigger it -
thanks
if i have time today i'll take another shot.
perhaps this time the triviality of my attention span will not...
and here's your multisim file to check it
to get the reversed quadrature i switched a q for a -q, not shown.
don't ask me how i mess this up so much....it's embarrassing...
is it self evidently...
gotcha - once again i mess up...
here's corrected clocking.
yes- as i say, i only had a 7400 model - in a real circuit it would use 74xx132 NAND SCHMITT TRIGGER.
i was also guessing that the encoder was ordinary ttl or cmos outputs.
ewb - Electronics...
omfg...
wrong pic
AAAAARRRRGGGGHHHH
maybe this time...jeez i wish i could delete allll the bad ones...
doggone it i messed up the pic
some days i can't do anything right...
so here's the right one....
ewb didn't have 74anything132, which is the nand schmitt trigger, so i used a 74hc00 for purposes of getting this done.
further division shouldn't be tuff...there's an orphan latch to use.
this has...
okay- somehow i got the simulator working and here is the tested and working circuit
finally...
sorry for all the screwing around.
NOPE, ONCE AGAIN:

well, EWB has the fabulous 4 channel virtual scope but not even a 74 c or hc or hct 14...
altium has the parts but no scope...and i'm not good enuf with it to figure out how to simulate with it....
it's very hot here and no AC..i sort of brown out when i try to think hard...must get AC...
here's the missing ingredient, then...
i have not simulated it, so maybe there's a defect still...
i...
ok, i think i have it - but This time i'll simulate the sucker and make sure so i don't wast bandwidth and ppl's time again.
i hve to do a lot of running around today, so sometime tonight.
