do you have any experience with bluetooth? specifically the receiving end of a headset
LawrenceG: Yeah, I use the same headset for my cellphone and my PC
LawrenceG: you having problems pairing ?
I want to mod my mobile 2m radio for handsfree.... but I need something like a dev kit to wire into the radio that will add vox
and stream audio in/out
so you want a BT transceiver with PTT ?
I have a headset, but I need the other half.... yes, vox would be nice as radios are not full duplex
LawrenceG: give me a few moments to think...
the only thing I have found is the usb dongles that plug into a computer..... damn... my radio doesnt have a usb port!
LawrenceG: give me a few moments to think...
The local govt hear is bringing in a handsfree requirment... and so far it doesnt look like hams are exempt
[02:54:30] <Jymmm> http://www.k7sfn.com/projects/bluetooth.html
and if your rig/ht doesn't have VOX built in, I'm sue you can find a little circuit easily.
[02:58:13] <Jymmm> http://www.blueparrott.com/products/blueparrottb250XT.html
LawrenceG: the key to is it this http://www.amazon.com/Jabra-A210-Bluetooth-Adapter/dp/B0006HES2I
LawrenceG: And you might want to buy a couple of them as it looks like they might be being discontinued http://www.overstock.com/Electronics/Jabra-A-210-Bluetooth-Adapter-for-Non-BT-Phones/2522208/product.html?ci_src=14110944&ci_sku=10740180
cool.... I wonder how you pick which headset they will associate with
you pair it
LawrenceG: Bluetooth has a "pairing" process
what if you have 3 headsets and 3 radios in the same room.... there is no computer involved to pair them up
LawrenceG: usually you dont have the radios in pairing mode at the same time
LawrenceG: Besides, there is a code you enter durign the pairing process for jsut that reason
the a210 plugs into a radio that only knows audio and ptt..... the headset has no operator interface.... who does the pairing?
It's always numeric, 4 to 10 digits. headsets are usually '0000'
LawrenceG: RTFM =)
the a210 may pair with any headset..... could be a lot of fun mobile.... some guy pulls up beside you and starts talking on the ham radio
Answer/end calls via headset ... there is some magic signally beyond the audio in/out

sent the epay guy a question to see if he will ship to Canada
I wouldn't. too much of a pita
Yeah, I'm not going to wait in line at the PO for 40 minutes to ship to .ca
or longer now that it's xmas time

the fm radio connection is an interesting idea for a handheld
LawrenceG: how do you plan on connecting that to your radio?
that to a210 to radio
so any background noise can trigger the VOX =)
LawrenceG: there ya go, play some muther fscker gangsta rap yo
and forget to turn off the vox
yea... the article you sent a link to talks about very good noise canceling headsets.... very important in the car
LawrenceG: all you need now is VOX circuit (easy shit)
I think the current law says you cant use handheld electronic devices... mabe a tin can and a string would be OK
LawrenceG: a mic is not a electric device
LawrenceG: a mic is not a electronic device
or every EMS worker is breaking the law
motorola ones are.... well, emergency vehicles are exempt.... I work with the local fire cheif.... I could probably get Vol. fire dept. plates
LawrenceG: is this all of canada or just BC ?
BC, but several other provinces have the same issue
the law has passed for Jan 1, but they havent written the regulations yet (IE... they dont have the tickets figured out yet)

someone is asking about cutter-knife control
something that would keep the blade tangentially aligned at all times to a path in the XY plane
has anyone done that with EMC?
I remember it being discussed
awallin: that would be great feature in emc
either let the knife follow
I would generate the gcode to rotate the knife as a post process probably
apparently Mach has something like that by default
I have seen it demoed in mach
or something like it
what about using a hot-wire?
roh: it is for cutting and press thick paper
uh. i see.. so like a cutting-plotter?
how thick paper? ive heard there are cool cheap cutting plotters from china with some 'printer driver'
seem to work fine from dxf i've heard
I not heard of 'fine' working chinese control program for machines ;)
every chinese machine we boy must convert to emc to be usable :D
but who knows
micges it works as a simple printer as far as ive heard... got etherent and a cups module
oh I see
this could work
a drag knife
ah.. i see... seems to speak hpgl like dialect on usb or serial (the cheaper versions)

anyone into spindles?
been doing a lot more RL stuff, hiking and such - less basement dwelling
jmkasunich: Ah, don't most do that in the summer/spring and not fall/winter time?
I've been doing it since spring
Yeah, I guess haven't seen you much around since then. Cool =)
jmkasunich: What's her name?
heh, no her involved
Heh, just sounded like it is all =)

get me down from here!!
heh, doesn't bother him a bit
I have another pic around where he is on the next ledge up, and I'm where he is
I'm sure he would have been happy to go all the way up, if I did the same
looks like a fun place
also, looks warmer than now
hmm - someone had to take the picture.... ;)
august, and yes, there were others - I hike with a group that ranges from 3 to 30 people and a similar number of dogs

That fall looks "man made", like someone poured out concrete - but I suspect it's just the low-res image
it's cool though
the falls is shale- thin layers that erode into a bunch of little ledges
thanks , i will try
cradek , what can i do for the gaintry?
have you slaved the 2 drive??
to follow the first or master drive
it is not problem to slave the drives , for to work as it has to be , must be homed separetely with its own home swith , otherwice the gaintry cannot be aligned to the table
but what i found thill now , is that there is no solution that can be made with the standart hal components , i will have to study the sources to find solution
are you homing to just switches, or is it servo with index?
for just switches, I think you can do it in hal
for index, it's much more complex
it is servo with index and separately home switches for each axes
i am trying to make a profesional machine
it is 7i43 + 4 servos and 2500 pulses encoders
anyone into reasonably priced spindles?
oddname is now known as frallzor
as in tops around $900
issy: sorry I don't know a good way to home two servos to index together. seems like you will have to dig in.
this is an isue that must be solved
great, keep us updated on your progress
let me send you some pictures of the machine , in 1 min , just to upload them
neat, give us the url here
is homing 2 steppers a solved problem?
eric_unterhausen: I think it's fairly easy to home to two switches (stop the "behind" motor until it hits its switch too, then tell emc the switch has been hit)
er no, stop the "ahead" one until the "behind" one catches up
you know what I mean
you can do that just in hal - easy
[18:28:15] <issy> http://imagebin.ca/view/cVtTzMY.html
why couldn't that be done in a servo? something changes state like a "switch" there too
eric_unterhausen: perhaps it can, but I think the index part is more challenging
I would try to solve that mechanically so the indexes are very close
issy, nice machine
[18:30:41] <issy> http://imagebin.ca/view/lAAXioLO.html
should be able to rotate the motor in a coupling
this is the control , made with touch screen lg monitor and dedicated kbd fo the machine , works fine , just the 2gaintry is not solved yet
issy: now you're just trying to hurt our feelings :) nice
no jog wheel?
the jog is separately and usb plugable , so it can be used at any place of the machine
the usb connectors are placed on the front panel and in both sides of the gaintry
what drive system? belts?
i am using pic microchip + ftdi , so it comes to the main PC as virtual com port , then is easy
noooo , no belts , the 2X and 1 Y is rack and pinion , the Z is ballscrew
this is working at 45meters per minute and the gaintry is 200 kg. no way to use belts , and then with the rack and pinion , i can make machines up to 20 meters long
so you are using a key to hold the drive gear on the servo shaft?
assuming commercial parts, I would also assume that the index would be very close on both axes
the system is made X- 2 motors 3000rpm/4Nm + 2 servo gearbox atlanta 6,8 div + gear mod1,5
the y is made wyth same motor , but planetry gear box
and the index can be anywhere , because there is no shaft on the coupling of the motor and gearbox
then you can adjust the index relative to the gearbox
but I would set up a "virtual index" by finding the relationship between the two
but this is not a problem , when alaining the system , i can stop the motors at index and then to fix thenm to the rack , so can be asumed that the indexes are too close
with the fanuc systems i use in the past the homing use the folowing procedure
at homming both motors searh the home index , the firtst trigger the swith , and stops waiting the seccond , when the seccond trigger , both are looking for the index
then is important to watc the unaligment while working in certan number of impulses from the encoders
only this will asure you that when you cut sqare it will be square , not romb
I agree that's the way to do it
to start the search for switch, you only have to move them together - one might be slightly ahead, but not much, since it will still be nearly aligned from last time
exactly , as big is the gaintry , big is the elasticity
I didn't exactly follow, but it doesn't seem to be that difficult of an extension of the current system
1 isue is that the 2 motor is not an axis , it must be jointed
that part is done as I understand it, the homing is a little different for servos
and the command from the axis to be copied to him , bit controled separately
yes, one command from emc goes to two pid/motors
then in the hal , it is not a problem to create a comparator for the both encoders to see the unaligment
and to push it back tho the gui
I don't see a need to push it back through the gui
so , my first problem is haw to create join to existing axis and haw to copy the command
to push it back , is in case you want to see the behavior during it's work
that is something best done with the halscope or the pyVCP
in my interface there is a special page for all the parameters to be analized and aligned
once you get it to work, you will not care
yes , but you must get it to work first!!!!
that's why you set up a VCP
it can be also
but this is not the problem
i have to go on the sources to fix the gaintry isue , any sugestions from where to start?
do you have the command going to both axes?
homing is the only problem?
in the ini file must have all 4 axis
for the backlash and the other thinks
cradek , haw to create the joint to existing axis?
cradek , is there any planes to support this in the future versions?
a Mechmate etc would be identical setup wouldn't it? how are they done?
mechmate, what what
2 servos on the gantry
what about it? :)
so you have separate home switches for each end?
^do you. I don't want to presume, I'd just have one myself :)
I think not, but not sure
Im not that far yet :PÅ
but seems "overkill" if both motors are linked to one axis
It seems dodgy using the 2 motors to align the gantry
I used 2x motors for my first build
worked like a charm
2 motors on an axis is the way to go for a big gantry
yeah but the stiffness of the gantry should keep them aligned?
easy to get racking
1x motor works with the meachmate too though
but then again, you ned a bigger motor so 2x is better anyway
I'd still prefer to have them linked mechanically, by a belt or sth, so a software/electronics fault can't twist the metal
and servos, would a single encoder be sensible?
wouldnt that be like using 1x geckor for 2 motors?
you could run 2 geckos off one encoder I'm sure, if the motors are mechanically connected
and I'm still not convinced you can't run 2 steppers in parallel off one driver :)
I must see the magic smoke for myself
should work but isnt the issue current and voltage? =)
I have 3.5A driver and 1A motors
either shitty performance or a magical smoke creator
luckily the driver can be throttled to 25% and 50%
anyway, I'm just trying to help deconstruct issy's problem now.
today is machine upgrade day... gotta do limit switches and wire up my toolchanger and front pannel.
actually home switches
i need to find a good place for my 7i42, 7i33, and 7i37
anyone have any cheap and easy ideas?
computer case is kinda full
hmm good quality 1.6kW spindle or dodgy 3kW chinese spindle
what kind of machine?
spindle for my mechmate build
1.6kw is solid
not familiar with mechmates
the 1.6kW seems to have bearings suitable for axial forces too
while chinese seems to be more of a radial one
what kind of rpm's is your tool going to be running primarily?
cant really say now
depends on the sizes
both do go 24000rpm max
i probably cant help ya, i'm more of a heavy iron guy
my motors are 1700-3400rpm and 3 phase
well at least 1 thing in common
totally different torque curve :)
3 phase =)
got a nice danfoss to get it going too
my mill is 2.2kw and it'll take a heavy cut
my manual mill is 1.5kw and it's pretty solid too
ill go with the 1.6kW then so i can do drilling too then =)
and use a ball-end without worry
[20:41:53] <frallzor> http://www.youtube.com/watch?v=uGQ2J4GgXkg
theyre using a router to do that, but a nice 1.6kW spindle should have no issue with that type of milling?
in MDF sure
well yeah wouldnt use one of those in metall or something =P
it's a rather large too :)
thats what she said
hmm i need to put in a 3 way selanoid for my spindle brake
wonder if the chinese spindle really is 3kW
[20:47:42] <frallzor> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=390119265838
sure, it'll draw 3kW. that's easy to measure :)
how much of that is turned into torque and how much into heat is another matter.
I reckon the quality of the bearings, and the ease of obtaining new brushes are the key
probably more heat, why else the watercooling :P
if im not mistaken this type doesnt use brushes
it doesn't look that dodgy to me
but this sealed the deal kind-of "DB- Double angular contact bearing in spindle nose and tail" for the 1.6kW one =)
yeah, like a bicycle wheel :) (probably what I'll be replacing my dremel with)
ah 2 sets, even better
and then it comes fron .Nl, so support should be better than from china
yep. certainly quicker
and with more consumer rights
or at least it's easier to sue them, if it's commercial
yeah a seller on ebay probably wouldnt care about that =)
oh the 1.6kW one is there too?
its just the "dodgy" on
others are from damencnc
well you pays your money and takes your chance. my 30e dremel thing never even got on my machine
I know damen is ok so I guess ill go with him =)
and I can't find the receipt. I'll have to fix the damn thing
now that IS the brushes :) or the speed controller
brushes are evul!
sometimes. I'd rather trust a lump of graphite than a crappy transistor
VFD is the way to go at the high quality end tho
yup I got a cheap danfoss vlt 6011 =)
7.5kW and like 16kVA
overkill, yes, but the price was right and I could upgrade in the futurer :P
yep, a mechmate looks strong enough to carve engine blocks
with a 5axis thingy and one of those long ball mills
will be interesting to see what it can do
I wonder if you can still get parts for that oval-piston Jaguar
wouldn't square pistons be optimal when considering the space needed? 8)
rounded squares, to avoid hotspots and stress
if the bore was curved, you could lose one joint in the connecting rod
ah the oil will run out before it's built :)
wooow "only" 805 euro for the 1.6kW spindle :P
time to rethink I guess!
can you describe again what is your problem with gantry?
well , generaly to work corectly , it must be homed separately , with own home switch for each motor
and the system use servos with index
frallzor -> http://www.youtube.com/watch?v=LqLFtpJQakM&NR=1
and he's a swede
doesn't say whether he sells them tho
if it is the person i think its just a project =)
(from a swedish electronics forum"
issy: homing and jogging gantry issues will be fixed in emc 2.4.0 (I hope we make it in time ;))
it is :P
805e would buy a cheap lathe :)
when you think it will be?
or a good small spindle :P
ah but then you'd have a lathe too
but no spindle :P
until you make it
issy: it's huge work half done
first a working mill, then other machines =)
maybe I can help?
that was my plan, until I tried to drill my own solid motor connectors
and started to wish I had a lathe first :)
i want that spindle! :P
ruin the euro for me please
it costs to much
use a black & decker until you've earned enough
cant to, doing electronics now too :P
so no proper spindle, no vfd setup :P
any syncronous AC motor should do
if it is speced the same that is =)
I borrowed a nice old asea
[22:19:48] <jt-plasma> http://www.youtube.com/watch?v=swulPjzzRQA
mm fitted with emc2. that's a telling expression :)
I'm not the only one who wants it embedded in rom
you guys should get together and make it happen
well I got the eprom programmer :)
what uses an eprom nowadays?
or do you mean jt & hardinge man?
old printers do. the plan was to use the printer cpu as-is
80188. thought it would be useful
and if the stepper drivers were bigger, it probably would be
and you can program flash chips in the same programmer. handy for bootstrapping without jtag
or if I brick a mobo trying to put coreboot on it
you can just use the hot swap on mobos
unless you want to use both halves for coreboot
well hopefully I'll do sth useful with it one day
right now, I want CF in my emc machine. IDE drives aren't worth buying anymore
hmm ER20 vs ER25
any ups and downs?
ER25 won by 1.4m to 750k, but there's an earplu called ER25
and also one named ER20
so the result is basically random
"ER20 collet" v "ER25 collet" is even more emphatic win for ER25
but random isn't that bad way of choosing things!
too random for making a choice this big =)
size is the only difference it seems
max 16mm tool instead of 13mm for ER20
we got ER25, and it seems nice
