SWPadnos: I know, but I'd do 20/20 over wood
JymmmEMC, that's what I'd use as well, _but_ there are people making small hobby cnc routers out of plywood, and they're acceptable for this application.
Eh, to each his own I guess =)
As a separate project, I'd like to build a 5' by 10' router some day. I'm not going to use wood for that.
DUCT TAPE!!! LOL
I believe all the cool kids are using plastic cutting board.
Humidity is a significant problem with wood
there been claims that hard wood ply is pretty decent
It's not a perfect material by any means, but this guy: www.mikebeck.org , is selling USD$400 CNC-ready router kits. For this hobby-type application it's probably appropriate, and getting a USD$1K aluminum CNC-ready router / mills is probably overkill for RepStrap builders.
he doesnt sell the screws?
what else do you need to make the $400 kits complete besides time?
renesis, damn. You're right. Well spotted.
yeah i was like how does he make it move, and then i saw the empty hole
you can get a ready to run CNC system for under $2K, less a PC
yeah i have a taig 2019cr
likewise. But I'm trying to find resources for people doing it on the cheap.
i got it with 100oz+ steppers and a 4ch xylotex for like $1800
well, taig is small
the 5.5" Y kinda kills it
awesome machine tho, its its little box
but they make it up in frustration if the kits are not complete
be cool to have a big router you could throw 2x4' or 4x8' sheets into
*nod* but the versitility of the taig is incredible
renesis, there's lots of options for big routers.
yeah ive used it to mill heatsinks in Al, done circuit boards prob within .010" easy
everything just works out of the box, unlike the horrorfreight specials
i dont even have the space tho
I've done CRS on the taig and it didn't complain
regarding the taig, I don't know of a well built machine that's somewhat bigger but also inexpensive. Maybe the Jet brand mill/drills.
for the money and size its awesome
i dont even thinks its 100lbs
jet isn't so good
80 lb, I think. No manual, which is annoying, but the taigtools mailing list does a good job of making up for that.
Looking at the plywood cnc router kits, I think they usually don't include the steel shafts or leadscrews, because the user can supply them.
not like the kits really have a manual
sebastienbailard: do the kits say what kind of ply to use?
Wood is of the finest clear Poplar, oversized by 20% in thickness.
Plywoods are of the finest Baltic Birch, imported from the Ukraine
that makes me chuckle
but you proabably won't beat the price for a router.
heh... good, cuz I had some rather "interesting" experiences with softwood ply
It reads a bit like SkyMall, but the people building them seem to be happy.
if you're strapped for space, and only want to cut 4x8 sheets
you could build a panel-saw type router
I'm going to build a smaller cnc router from wood using the solsylva.com plans, and later I may build a 5'x10' router using the mechmate.com plans.
i love how larger manual machines are cheap
people are paying 8000 for a 15x80 grizzly
yet a 20"x94" pacemaker goes for 700-1000 bucks in pristine condition
SWPadnos: Damn.... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=020&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=300115146431&rd=1&rd=1
SWPadnos: Now, I'd hate to loose that phone in the back of a taxi
JymmmEMC: no worse then loosing a top of the line Treo
Not even offered in the US yet
Yes, Palm Treo...they were selling at $700ish
amada seems to make a pretty full-featured bandsaw
what i always wonder is what advantage a CNC bandsaw gives you over a plain automatic
it's not like you can do contouring
maybe if you are in the kind of business where you need '10 pcs 12" long, 5 pcs 18" long, 20 pcs 6" long' all from the same bar or tube
race car frame building? custom bike or motorcycle frames, that kind of thing
load the bar, set up what you need, and go do something else
i can see your point, but i'm not sure the automation justifies the expense in this case
30k to get tubes of different lengths?
maybe in high production frames
30,000 us dollars
s pretty expensive, but they've got a lot of automation to them
i think 25k is like the price for a bare-bones automatic
whats to automate? clamp at the cutter, clamp on a carriage to advance the stock, the carriage itself, blade assembly up/down
and the cnc models go up from there
the machanical parts are the same for CNC or automatic, and the "control" is cheap if you take an EMCish approach
they're pretty rigid though
if you take a "pay somebody for close source automation" then you deserve to pay to much ;-)
uh, that's clearly not the case as hundreds of thousands of businesses across america are paying 30k per saw
i don't know what's so special about the control, but the saw itself is very rugged
One place where CNC control might be useful is if you're doing a bunch of irregular length cuts all day, and you want to maximize your use of stock, and minimize your amount of offcuts, you have the computer figure it out, rather than having to reset the inputs on an automatic saw each time.
I doubt anybody sells 100K saws at 30K each, thats 3 billion dollars
at 30K, isn't it cheaper to get a dedicate lathe + bar puller?
I bet they sell a few thousand saws a year tops
ds2: not for all applications
not all saw work goes into a lathe
and not all lathes have a big bore spindle
the saw can cut things like square tubing, which would be a pain on a lathe
and stock bigger than 2" round
but for just parting off work, you can have a lateh with a huge bore like the stuff they use for threading pipes
have you priced big bore lathes lately
pipe threading lathes didn't seem that steep
also, cutoff at depth is difficult
easy for thin walled tubing
ds2: which do you think would cut more parts before wearing out or breaking, a cuttoff tool in a lathe or a bandsaw blade
but hard when you start getting past 2"
if its thin walled the cutoff tool might win because the saw would catch
it is just 30K is a lot for a saw
but for 2" bar, or 6" tube with 1" walls, the saw will win
go home time
my experience with thin walled tubing is that a bandsaw drops through it like butter
with the proper blade on it
guess it depends on how thin, and the blade
if you're talking 0.030 wall, thats not gonna be happy
you use the right blade, and it's fine
you just use a finer and finer pitch
in fact, a saw type vise would have a hard time grabbing a 2" tube with a very thin wall
so would a lathe
for a 2" tube?
in general I agree with you, there are only a few places where a lathe _might_ have the advantage
and that was my point in the first place
high production bar feed applications, sure
wins out even more if you add a sub spindle
there are so many more places where the saw wins tho
i agree with you. i am poorly attempting to point out that in the cutoff operation, it is difficult to beat a saw by much
1/2 x 2" flatbar for example ;-)

I'm 50% done the gerber import in GCAM now
why does everyone want a closed loop system with steppers and encoders?
so you can combat step loss
it's the only wat to know you lost a step
is anyone using such a system under EMC2?
But encoders cost $100 so forget it
not on ebay
and U.S. digital
and in printers
That IS the US Digital price
that's not that bad
buy a brushless servo
that seems a bit spendy, I can get brand new 600W AC servo motors with 2500 line encoders for $600
AND... all it will do is tell you that you skipped, not correct it
that's the problem, isn't it?
JymmmEMC, are you sure about that?
I'm pretty sure you could write a HAL file to run steppers closed loop
petev: what would you have it do when it sees a lost step?
issue another until it gets into position
try to catch up? that will only increase speed and/or accel and make it lose more steps
that's the same thing a servo system does
servos aren't steppers
nothing is going to help an overloaded motor, whether stepper or servo
can you set it up to throw following errors?
eric_u: yes, you could do that
I just answered a question about this on CNCZone, told them they were stupid to want it and go try to make i work on Mach
ok, so I didn't do that

I have one of these microscopes:
[04:46:13] <eric_u> http://www.company7.com/questar/microscope.html
it has high end linear encoders and steppers
they were running it open-loop, and not even reading the encoders
i'm configuring hal file, and i tred this: newsig spindle-speed-cmd float, linksp spindle-speed-cmd motion.speindle-speed-out, but i get an error: "pin 'motion.spindle-speed-out' not found". Why is tha...i already loaded main motion controller module?
kwaj: what version of emc2?
older versions of emc2 had iocontrol.0.spindle-speed-out instead of motion...
hang on a moment
are you sure you have no typo in there?
the rest looks as it should be..
will check again...
yes, you were right :)
sorry about that
hello, can someone please help me with this ( http://pastebin.ca/511229
). I wpuld like to configure pwmgen module, but i get no output on parport pin (i checked with osciloscope).
you need to addf the pwmgen function to a thread
addf pwmgen.make-pulses base-thread
i added this base-thread, but i still get no output, any idea what else could be wrong?
pwm-output variable is always false
spindle-speed variable is and spindle-enable is TRUE
spindle-speed variable is 5 and spindle-enable variable is TRUE
is it importat to add the addf command at the beginning of hal file?
maybe man pwmgen is helpfull
you need to add it after the loadrt
kwaj: there are some sample configs which use pwmgen.. maybe you can look at them
should i also set all parameters? What will be the default value for parameter if i dont set it (did't found this in man)?
halcmd show thread command shows FP=0 for stepgen.make-pulses....what is this FP?
halcmd show thread command shows FP=NO for stepgen.make-pulses....what is this FP?
FP is floating point
you don't need it for pwmgen
gone for today
guess I wasn't connected

isn't pin 16 supposed to be input (ie, parport.0.pin-16-in) in hal_parport's mode X? and isn't mode x loaded by `loadrt hal_parport "0x378 x"`? or have I got all my config lines wrong?
acemi_ is now known as acemi
if my steppers go out of bounds, axis.0.*-lim-sw-in is triggered, and the current call to sendProgramRun stops executing, but doesn't return. How am I supposed to recover from an out-of-bounds error?

"OH !!! SHIT my house is burning down"
hopefully they're not toasted, but I suspect they are.
catharsis, dude. now I'm stuck with the Y-axis only.
haha, my little Major stick figure can't dodge projectiles anymore
preserved for posterity: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?IRCquotes
if you're going to include me, at least stick in the q3a part! and "s/is/was/" means that this was all told in hindsight
its a wiki, fix it yourself ;-)
I just posted the most amusing part
is there a reason why hal doesn't include a rs-232 driver? maybe the rs-232 port isn't realtime friendly?
what do you mean rs-232? a driver that sends messages?
hal works with simple signals, like floats and bits
I meant serial port. isn't the official name of the serial port, "RS-232"?
I know you meant serial port
there is a HAL driver for the digital I/O pins on an "8250"-style serial port -- DCD, DSR, etc
"officially", rs-232 specs out the voltage levels on the serial port pins and not much more, but thats a side issue
the point is, when most people talk about the serial port, they mean serially transmitted messages of some sort
the driver jepler mentioned doesn't send serial messages, it just uses a few pins of the port as extra outputs (and maybe an input or two?)
jmkasunich: the "serport" manual page lists all the HAL pins and the pins they correspond to
what will happen, if i generate a pwmgen module, and i leave enable pin not connected...will pwmgen be enabled or dissabled?
I figured it did, was too lazy to look.... I'm assuming sudo_maddash isn't talking about that concept though, and I'm trying to get him to tell us what he means
kwaj_: if not specified otherwise in the documentation, the default value for a pin is FALSE, 0, or 0.0.
the default value of an unconnect pin is zero
kwaj_: you can also use 'halcmd show pin' to check
and "halcmd setp" to define the value without connecting a signal
jmkasunich: i'm lost. why can't a hypothetical hal serial port driver treat its port like how hal_parport treats the parallel port?
you mean just twiddle the pins? no baud rates or anything?
no baud rates. "twiddle"?
did you read the "serport" manpage?
if all you want to do is use a few pins as bit inputs or outputs, the driver jepler is talking about already does that
however, most people who ask about serial ports actually want to communicate serially with something
dumb terminal, modem, or more interestingly servo drives with serial interfaces
jepler: reading it right now.
* jepler wanders off
random question: with an encoder/servo system, how many steps on the encoder are you from ideal when machining? +/- 2-3?
that depends on how well tuned it is
during rapids (especially the accel and decel at each end) I bet the following error is a bit more than that
during less aggressive movement, it might be less, as little as 1
following error is available as a pin or parameter (not sure which offhand, use show) so you can meter it or scope it while running
[16:57:55] <jepler> http://timeguy.com/cradek-files/emc/final-tuning.png
this is cradek's servo lathe tuning
I think the scale for the error is 10 milli-mm
his encoder counts are _very_ small
and the input scale is 6000
2000 count/rev encoders, 3:1 belt drive from motor to screw, and 20:1 screw (I think)
I think 1 div would be 60 counts
I take it pid error is the deviation from where it should be?
so from cradek's lathe it looks like 6 steps when doing rapids and 1-2 with less agressive stuff?
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-05-26.txt
Is there a way to capture/measure mid-band resonance?
yes by a slow frequency sweep through it
which might be hard to do, since the axis will be moving in one direction the whole time, and might run out of travel
if you want to check motor resonance only, decouple it from the screw, then you can check as archivist suggested
also depends on available equipment /me would use a dynamic sysem analyser
Sorry, I meant when it does stall.
not entirely valid under stall conditions
archivist: doesn't the analyzer need position and/or velocity feedback from the unit-under-test?
dunno if you've been following the saga of JymmmEMC
he has a stepper machine that every once in a while loses steps
he really has no clue as to why, but one suspect is mid-band resonance
he has no feedback devices, and the problem is very intermittent
could be, we had it on a printer we made
full step or microstep?
Geckos have "Mid-band compensation", altering the phase (somehow), but since geckos don't have any feedback, I suspect it's an electrical thing that's being compensated. I was thinking of somehow reading those, but I dont know what to look for.
you increase power a bit
archivist: I have xylotex right now.
archivist: to be clear, JymmmEMC is not using Geckos, he's using something else, and wondering if Geckos would solve his problem
archivist: IT's at the limits.
then avoid the noisy speeds
archivist: I'm just looking to confirm that the issues I've been having are indeed mid-bind, and not the motors, a cable, or something else entirely different. Then I can justify buying geckos.
we evend damped the gears in the drive using thixotropic grease
archivist: You know the ngc file that loads when you start Axis? I can get even that to stall once in a while, but not all the time and can't repeat it either.
basicly if the drive is noisy its a sign of resonance
check the acceleration rate v the steppers limits bearing in mind the load it has
[17:50:17] <JymmmEMC> http://www.xylotex.com/StepperMotor.htm
Im used to the stepper problems but not used linux emc yet
JymmmEMC: just OOC, what type of speed are you running your motor at? continously sub-critically? or do you jump past often?
since the problem is intermittent, if it is a resonance, it must be one that in most cases the machine passes thru quickly enough that it doesn't show up
lerneaen_hydra: Can occure even at 40IPM
what type of motor rpm is that?
5TPI ballscrew on 2:1 pulleys
hmm whats the curve for the motor
what's in that link is all I have.
so around 6.5 revs/s?
that sure sounds like supercritical
lerneaen_hydra: I dont know
maybe you're loosing steps when going between 0 and that speed (like you were hypothesising)
lerneaen_hydra: I can rapid to 100IPM
JymmmEMC: oh, not bad at all
Kinda scarry at that speed too.
that's surely super critical
I can imaging
2500mm/min is fast ;)
I saw it once bounce the machine sideways.
not by much, but still.
try some different acceleration rates
I note that the pdf is missing the resonant speed, mass and max step rate of the motor
Also note the my steppers are square, and the pdf shows them as octalgon
I assume its just a badged motor from some other company I would check a few compatible data sheets
Ok, say I dont get the curves, then what?
the curve will show the resonance of the rotor (need accelerating through, preferably with plenty of spare power)
Ok, and if I'm within specs?
the max torque they quote is only stall, it drops with speed so dont go too fast
So I can rapid at 100IPM, but intermittantly can stall randomly at 40IPM ?
If I slow it down much more than I already have I start risking it becoming the ultimate of rubbing of two sticks together.
doesnt suprise me mechanical systems have many resonances eg stepper, any intemediate rotating mass and the moving mass
thats why you have to avoid the resonances stay above or below
And how would you suggest I do that?
play and listen avoid the noise
If the Geckos resolve the problem once and for all, no problem. But if the issues is something else, say the motors. then I might as well invest is (let's say) servo motors/drives.
or encoders on the steppers
archivist: it's random, unrepeatable. Yes, I hear it when it does stall. But how would you siggest that I avoid the noise? I have no way of reading (eletrically) .
lerneaen_hydra: $112.34/ea encoder US Digital.
JymmmEMC: :/ nasty
archivist: What am I to scope?
archivist: (no, but I've been thinking about getting one)
just listening to the stepper whine and find the quietest speeds
archivist: Ok, and adjust what? accel? vel? I can't repeat the problem. Even running the say gcode 10 times in a row after warming up the machien for 2 hours.
both acc and vel, quietest at max current
archivist: And when do I know I've hit a limit on either? I have no feedback (electrically) to base the setting son.
when it works best as you cannot measure
when it actually loses step and at what rate
What and how am I suppose to measure the loss steps?
you dont have feedback from the steppers so you cant
Then why would you suggest that?
* JymmmEMC FACE PALMS
5tpi screws, 2:1 pulley, 8microstep = 16000 PPI ??? I'm asking about the units part (PPI) not the value. Is that correct? 16,000 pulses per inch?
seems like if you are building a stepper powered device that you are using in production, Geckos are the minimum you would buy
so JymmmEMC , did you get your new drives and psu wired up?
robin_sz: I didn't get those drives, the seller canceled the auction (fscker),
and no more to be had (of those model#) on ebay, been looking.
They looked like really nice drives too.
better get a gecko then
Yeah, I'm considering it. But if I'm to spend $500, Id REALLY like to know wth the problem is and not just toss money at it to find out "that's not it" (say the motors themselves or some other issue).
5 axis machine?
g201s are only 114 dollars, 350 dollars will do it
$200 is a lot easier to swallow than $500. No the G203v, $147/ea * 3 = $441 + $20 Shipping + 1.0875% tax
thats 175 gbp
203V .. oh the expensive one,
nice of you have the money
I figure if I buy the g203V, and if my motors go out in the future, I'm not out drives too. and I could just buy nicer motors.
I don't mind the investment, Just need/want to justify it is all.
to be fair, it os often a bewtter idea to buy the best, especially if you can only afford to buy once
If I buy stepper drives, then find out it's motors that are the problem, then I'm out both. when I could have just gone servo and resolved the problem in the first place.
well, servo is MUCH more expensive to do
Yeah, I understand. But 24+ months of these issues is enough.
did you buy this thing to make money or just for kicks?
It was to make enough money to but a laser actually.
so, the sooner you fix it, the sooner you can make money
how much you think you can make? $100 a week?
Gawd I hope not =) I'd be broke within 60 days =)
presumably this will be a sideline, not main income?
Would be working towards main income hopefully/eventually, I have a couples of products in mind.
I'll be outsourcing the laser potion I need
then just make the investment, its a trivial amount to invest in your business
* robin_sz is looking at a new laser too
well, a second hand one anyway
Oh nm what I had in mind then =)
would have liked a 3k, but ...
This is 40W 48" x 32"
for $4000 complete
mine will be a bit more than that :)
not a lot though
$10K to $14K ...
That doesn't seem to bad
I need acrylic squares (various sizes), but polished edges. and doing it by hand takes way to long especially when I cna cut and polish in one pass of the laser.
this one im getting (hopefully) has been cutting acryllic
robin_sz: Just FYI, you'll be limited to 40IPM
if you want polished edges.
just fyi, I wont
this thing has been cutting acryllic lettering, polished edges, at way, WAY more than that
Hmmmm, maybe this one shop I talked to is full of shit then =)
Still getting quotes
probably they dont have experience with multi-kilowatt CO2
and they probably dotn have precision height feedback ...
Our 1k laser polishes edges at 40ipm
Well, these are small qty jobs lots too.
This is one place... http://www.sanjoselaser.net/
We use a 3600 watt Mitsubishi Laser system
skunkworks, the 2K im looking at was doing perspex lettering , in 3mm perspex at at least double or more that speed
looked polished to me
NO WAY would they be allowed to perate like that over here
look at theat 5 axis ...
Yeah, I saw =)
operator standing by it ... oops, sorry, was that your leg?
This is a prc brand laser.
* skunkworks is not up on the lingo - slab?
two flat plates, nearly parallel mirrors, beam walks out
single tube - forced air - mirror on each end.
ew, maint wise.
it has a blower similar to what is on drag racers
we have had it for about 15 year. blower was replaced once so far
1kw from a single tube?
it has a large hv power supply with tubes to control
ahh, yes a rootes blower
right DC excited
it is rated at 800w - but we have always been able to get 1k
those rootes blowers go on for ages and are self-serviceable
basically, just a bearing and seal kit
rootes - I could not remember the name
the one im looking at is rootes blower
better than the turbine ones IMHO, maintenance wise anyway
this one is RF excited though, so no electrode sputtering
No major problems with it.
is the DC side vacuum tube based?
or solid state?
it has a control circuit (solid state) that floats at what ever voltage that controls the tubes. run with fiberoptics.
4 tubes iirc
tubes are cooled in a oil bath
5tpi ballscrews @ 8microstepping, 2:1 pulley = 16000 PPI. Is the units, not the value correct??? 1600 pulses per inch?
typo missing a zero there
200 SPR motors
16000 steps per inch ...
100 ipm = 1600000 per minute ...
you need a maximum rt period of 19us to do that
quite fast ...
will your PC run relaibly with 20us period?
will the steppers still have any torque at that speed
No, No, I mean is 16000 ppi == pulses to move one inch?
only if 1 pulse is one microstep
robin_sz: 15000nS ovr max
so it's STEPs not Pulses per inch?
or can the two be interchanged?
1600 usteps or pulses
Wait, no I don't LOL
16000 is Steps necessary to move one inch?
16000 is Pulses necessary to move one inch?
what part of 8 microsteps per step is hard
If I knew, I would not have a need to ask.
they are partial steps, not accurately defined in angle between full steps, done by fiddling with the drive signals
I'm just asking what units they are in, nothing more, nothing less.
"microstepping" increases the number of pulses the PC has to issue to turn the motor shaft by a varying amount.
"microstepping" increases the number of pulses the PC has to issue to turn the motor shaft by a particular amount
its a smoother drive but has lower torque on some intermediate microsteps
and the angle of turn is not exactly 1/8 of a full step it varies
from the standpoint of emc, if you change the stepping from "full" to "1/8", the inifile SCALE is multiplied by 8
16000 is Pulses necessary to move one inch
JymmmEMC, ^^ that
you may be better off with a G210
why the 210?
203 is 10microsteps
it will smoothly microstep the motor, 10 nice smooth microsteps for 1 pulse
I'll loose resolution if I use their multipler.
but you wont be able to drive the G201 at the same speeds with emc
JymmmEMC, dont confuse resolution with accuracy
I have 15500uS ovl max base period with emc, why wouldn't I?
the 201 is 10 usteps ...
you think you can do 30khz from emc reliably? if you can, then you have it sorted, no worries
Isn't 16000 about 22KHz (I dont know the math)
thats for 8 usteps
the gecko is 10
16000 is 26.666 k .. I did the math for you earlier
at 100 ipm
of course, you could just do slower G0s
so 200SPR * 5TPI 2:1 pulley and 10uStep is 20000 base period?
for 100 ipm?
no, no, to achive that
to achieve what?
200SPR * 10 TPI leadscrews = 2000 * 10uStep = 20,000
20,000 steps per inch yes
as opposed to my 16000 @ 8uStep.
now .. tell me a speed, and I'll tell you a frequency/period
So, to use those settings, I'd need to reduce what? just accel?
no, the machine is PHYSICALLY the same
Well, I'd like to be able to do 80IPm rapids
so the physical contraints are unchanged
I just said that I *CAN* do 100IPM currently, that's all.
I need to be able to do 40IPM minimally, better with at least 60IPM.
well, 80ipm will be 26.66khz, same as before
Ok, that's cool. Plastic doens't like slow moves =)
As my spindle is limited to 8K-25K RPM's, I don't have alot of room to play on that side of it.
single fluyte cutter?
No, O-Flute cutters, 0.01" top engraving, and V-Cutters.
floating nose cone?
Some engraving, no floating.
you will need a VERY good machine to do any decent engraving without a flotaing nose cone
any vertical movement when it accels/stops ends up as crappy round circles from the engraving tip
it needs to be quite rigid
and you have to get the alignment of the head and the material very flat
or the engraving width changes
thats why commercial machines cheat and use a floating nose cone :)
it compensates for misalligned material heights, and crappy mechanics
robin_sz: I havne't had too bad results (excuse the photo, poor lighting made it out of focus) http://farm1.static.flickr.com/84/206158222_cb5c34978c_m.jpg
That's on a 3" disc.

machine cant be that bad then
Other than the stalling, no it hasn't been at all.
It's not a hass by any means, but...
where can I find the documentation for 'emc.nml'?
psht. wise guy. I'm only asking because i've grepped the wiki, all 4 .pdf docs and the html man page.
What? I hate wikis (in general) and google has done a nice job of indexing the site.
your words have been immortalized! LOL
You've been googled! hahahaha

[sigh]. well, back to trial and error.
