do you guys leave your controllers/pc's out in the cold with no heat?
i live in a place where temperatures are generally sensible ;-P
anybody done anything with rotating ball nuts?
its 27F out now.
its a new idea to me
[02:09:37] <r00t4rd3d> http://reinventingscience.wordpress.com/2011/03/18/harris-educationals-new-computer/
i also live in a place where we measure temperatures with sensible units ;-P
i need to make that case so I can put my pc and controller in one and be able to move it easily.
r00t: see the new vectric freebie project?
hah, nother botx
my 60-degree vbit showed up today
along with my new atom d525 I purposefully avoided buying from newegg... it came dropshipped from newegg by the amazon vendor
I even paid a few $ more to not get it from newegg
lodge a complaint.
anyone tried linuxcnc on a Intel Innovation D2500HN
same chipset as d525
Not the one I'm thinking then.
there is one you can power with a 9v battery
8-19VDC DIRECT, no PS needed... http://www.mini-box.com/Intel-DN2800MT-Mini-ITX-Motherboard
nevermind... has no pport. looks like dual ethernet, dual serial and dvi though
The specs on that page are incorrect, it DOES have an intel nic
oh, they corrected it already
3/4" tall =)
half height atom
i just looked up my d525 operating temps
Non-Operating -20 °C to +70 °C
i dont care about the hd
we dont care that you dont care about the hd
It also has LVDS , but the connectivity to it needs to be researched in advanced.
we dont care that you care about hd
whack... lots of different pics claiming to be d2500HN, some with pport, some with 1 ps2, some with 2 ps2
D2500/2800 have poorly supported video hardware for linux
so dont expect stellar video performance
I got another d525. Also not stellar, but it only runs axis
jdh search for intel brand
not a clone board
or with the same chip
Technical Product Vrief is 100 pages and goes into detail, theres a LVDS one too http://www.intel.com/p/en_US/support/category/dsktpboards/db-dn2800mt/doc_guide?format-type=Technical+Documents
Intel BOXD2500HN Atom Dual-Core D2500/ Intel NM10/
jdh: from the horses mouth
that's not the same board though.
Your looking at a mobo that's end of life.
but, the intel page does show a pport. Glad I didn't see it... it's $20 cheaper
that's not really an issue.
I have boxes at work that were EOLed 25 years ago :)

they seem super rare
never seen one. looks nifty for huge not long parts
yeah, which is most lathe work
50-60" swing lathes are cool but they usually only swing 30" or so over the carriage unless it's a roll lathe or similar style

If you run linuxCNC, is there a specific pin on the parallel output of the pc that is always 1?
there may well be a power pin
I'd suggest looking at the pport spec and seeing what it says

[08:09:37] -!- plushy has quit [Ping timeout: 256 seconds]
aren't pport pins open collector or something similar?
alas, I have no clue what that is ^^'
some/most are but it varies
it means you will need a resistor to ground or power in order for it to actually toggle
perhaps it might be an idea to describe what you are actually trying to do pilla_
sometimes the pull up is internal some times not
and not all pins are the same iirc
I want, that if my CNC machine 'homes' (I have no homing switches), that my x, y and z limits get triggered
probably varies with the mode of the pport too
why not just turn homing off?
I want to make homing switches
so when you have them wire them up ;->
[08:16:21] -!- herron [firstname.lastname@example.org] has joined #linuxcnc
I don't have them
I want to make them
(we ran for years without homing switches lol)
yeah, but you are trying to do this weird loopback thing and i can't work out why
if you presently lack homing switches, just turn homing off
I want to put cables on the x, y and z axis
when you then gain homing switches, wire them in
and if they touch the "home" position, the pins should get active
I just don't know how to make those pins active
ey archivist, we are building a new wood/Al mill/router we want to do some detailed type profiling, I'm thinking of going to rotating nut ballscrews rather than spinning the ballscrew
either putting another cable on the home position so that if they home, the pins touch that cable, and a 1 signal is sent
reason being is we are going for a 1200mm work area
pilla_: is english not your native tounge?
nope, is it that obvious? D
any thoughts archivist? looking at hiwin brand screws and rails
pilla_, as long as you set a pin to be an input then you can short it to gnd
for somebody with english as your second language your doing pretty well, if it was your major language I'd get up you for talking imprecisely about precise stuff ;->
I think my 5 axis has some hiwin (got them surplus)
Haha, sorry, my english knowledge isn't very technical ^^
but yah as archivist said, if you make the pin an input you shouldn't be able to hurt it giving it either 5v or gnd
So I can short them to ground? That was exactly what I needed :) Thanks!
make *sure* its an input first
I still have no homing switches !
archivist: any idea what the pullup is on one of them
I got around to hooking up the index pulses on our glass scales for homing
I think dad's used it twice in 6 months ;->
LinuxCNC assigns the x limit, y limit and z limit to pins 10, 11, 12, so I suppose those will be/stay input ports? :)
note the limit is not the same as a home input
330 ohms is a lower value I think I have seen
I was thinking he could probe with a resistor but at 330ohms it'd be kinda pointless
[08:23:35] -!- dhoovie|2 has quit [Ping timeout: 246 seconds]

[08:30:36] -!- asdfasd [firstname.lastname@example.org] has joined #linuxcnc
it looks like it, the issue we were having was the critical speed
for the ballscrew
with 1200 travel we needed 25mm to get a critical speed of 1200
we could go to 10mm lead which would hit 4 meters a minute at ~500 RPM, but we'd need to double the gearing which was already like 5:1

there is an option to use limit as home i believe
you can add another parallel port for more io
pilla_: use switches for limits and homing
Yay more chance to fry the PC :D I've been looking in the homing sequence again and actually I don't need two switches ^^

Yeah, I understand.
and it is made worse by camera object distance
I was just kinda impressed with how fine the crosshairs are
on avg 1/72 of an inch
what would be better is to mount the camera on a stage under cnc control so one can see the real measurements
Well, if the Z doens't change much. You could calibrate against a steel rule placed on the table maybe.

So um my teacher doesn't mind the CNC machine hitting the home limits... so can I set it in CNC that once the machine trips the home switch, it just "stops"?
without going back and blah
in linucnc that is.
home and limit are very different things
though you can use a limit switch for homing I believe
do you understand the difference between the two?
a home switch is to tell the mill accuratly where in its travel it is
[10:07:49] -!- sumpfralle [email@example.com] has joined #linuxcnc
so if you have a jig on the mill you can return it to the same cordinates each time
[10:08:34] -!- mk0 [firstname.lastname@example.org] has joined #linuxcnc
the limit switches are there to say "you are about to hit the end of travel on this axis you should stop now"
So if I only use a limit switch, the machine just stops when it hits it? :)
when you have homed the mill if you have the limits set in the software emc won't intentionally hit the limit switches either
thats the purpose of a limit switch
Ok, thanks ;)
to stop you from driving into the end of the axis
if you are really feeling an I/O pinch you can join all the limit switches together onto one pin i think
Oh but my teacher said he doesn't mind the machine driving into the end of the axis.. So I'm just going to use limit switches on the end of the axis.
But then I'd need 3 pins right?
(with 3 axes)
he doesn't mind it pushing at full power into the end of the axis?
or he doesn't mind it hitting a limit switch?
He doesn't mind.
He doesn't mind the first ;)
then don't bother with any switches
archivist runs to this day without home at least and i think without limit
we run without limits and only sometimes home
Then how does he, in a software-way, have the machine "home"?
My teacher wants me to be able to do that
its not a requirement
you can turn it off
Because it makes life easier.
Because he wants noob students to be able to push a button so the machine homes, put a print board on the miller, take a picture with a cheap webcam of the print board, point to some places on the picture, and have the cnc mill there.
I don't exactly need it to home, but it's difficult to (without any human intervention) take pictures of the board if the machine doesn't know where it is
so if I home the machine, I at least have a reference point
if you go and "take pictures of the board"
then you are touching off
you don't need to home
I know that, but I want to be able to take a picture of the complete workspace
to what end?
don't understand that sentence, can you rephrase? :)
I can see why your teacher wants proper homing
touching off is just setting 0 to some reference eg a corner of your board
That way I can also prevent people from using commands that exceed the machine limits (if I have a limit switch)
linuxcnc also has soft limits so it should never hit the switches in practice
My teacher thinks it's the most precise to have the machine hit the hard limits, then you know exactly where the machine is
...I don't complain, it's easiest to make this way xD
homing is not hard limits there is a difference
I know but he asked to hit the hard limits so I don't need homing anymore. If I have my own cnc miller I would do proper homing, but here teacher's boss.
I'll just use limits
hard limits would be less accurate than a good home switch I'd reckon
just due to bending the machine
mmm, I don't think this machine is powerful enough for that

L84Supper where are you having issues sourcing acme screws and nuts? if in USA, mcmaster.com. If in Canadaâ€¦ there's a place called durham fasteners, near Torontoâ€¦
alpha1125: yes, the prices there aren' that great, probably since they are one of the few that actually keep stock
fastenel is worse.
what are you looking for specifically? I ran through all these things like 10 years ago, when I start playing around with CNC.
first time I turned on my mill in over a year, was last weekend.
yeah, I ended up buying longer lengths and then will machine them to size
but of course after ordering them, I now find N.O.S. on ebay only 5 miles from me
go check them outâ€¦ it'd probably be worth your timeâ€¦ if not, just another place to source stuff for the future.

usually z0 should be the top of travel, so g0 g53 z1 is normally an unreachable position
cradek: until the ref switches are a few mm before the end of travel
sure, but the position of the switch does not dictate where your zero must be
no, but usually is
if not configured otherwise
that's not really my experience, but I don't care to argue about it
normally I see zero being exactly one end of the allowable travel
but there's no reason you must do it that way
my machine is configured this way also: travel goes from x-2 to 202 ;y -2 to 112 and z 2 to -112
regulat movement is only 200*110*110, the 4mm in each axis are "spare"
a commercial machine I used to have was travel x 0..18, y 0..12, z 0..-5
and the ref switches sit on 0,0,0
the home switch and index pulse were inside that region somewhere
z0 is hte surface of my PCB copper
Mjolinor: that's a workpiece origin; we're talking about the machine limits established by homing
what i meant: the excess travel is not meant to be used "regulary" but is there for breakung pourposes and for the occasional workpiece which is "JUST that small bit" to large for the machine ;-)
but I home to one corner of the PCB
so X Y and Z are all homed to the front left corner
you do not use workpiece origin? g54 etc?
using homing to set your work origin means you do not have the protection of axis limits, and you don't have a useful g53 coordinate system
Mjolinor: does your machine HAVE ref/home switches?
ah, there ;)
you can still home it by jogging to a known location. put markings on it.
end of travels, for instance
doing this gives you many useful things
gettting work done seamlessly after some crash or step loss
I can home like that but if I want more than one PCB rather than lay it out as multiple I cut one then move the origin for X and cut another
for example ;-)
you can still do that with g54
Mjolinor: for that, use workpiece (g54) origin, set with touch off
wow the forum is really busted today
more details? I don't see anything wrong at first glance.

pcw_home: do yyou got 100w AC drivers in your boards
for a UVW servo
No not 100V
i have alock
7I39 with the right transistors maybe
are UVW servos always DC
the motors run on 3 phase variable frequency AC
my R7m reads 200V 0.87A
im still strugeling with the Mind to understand how this systems work
my Xtradrive from Ebay has a Encoder input and 230V AC also UVW
it might read analog and puls/Dir
so on pulse dir how does the controler act ? on its own mined
What do you mean by "UVW"?
U/V/W from encoder is commutation signal
no the Servo power
(equivalent to "Hall" signals)
with a step/dir servo the drive has a PID position loop and a up/down counter that the servo PID loop follows
and for understanding on Servo analog how does the controler Pc knows the back signal if there is the encoder to the Driver
IchGuckLive: Often it doesn't.
most drives can echo the encoder signals back to the controller
But many drives pass-through the encoder signal to the PC.
i got 3 connectors i ill have a look on the pins
If you _only_ have three pins, then you need a sensorless drive and it's not likely to work for CNC,
if it has an analog controller interface, the controller (LinuxCNC) needs to have the encoder signals
(well not always a system with linear scales might just have the scale count go to the controller)
i got it there is a signal transmission
andypugh: 3 connectors with 30 pins plus
That's almost worse. I wonder what all those pins do?

no cable at all
look inside, reverse engineer
they OMRON and Ysakawa helpt me by PDF the Cable pinlayout now i start soldering
thanks the pinsolder are 2,54mm
so maybe good luck one time
first i need a other encoder this on the motor is broken maybe i killed it on messuring

hi skunkworks, basicly: the impossible

Im trying tosetup a arduino2emc
gah frekin ebay sellers do not specify if the V groove bearings are double race or not ...

mevon_, I have used this and it works very well (using it to get temp into linuxcnc) http://emergent.unpythonic.net/01198594294
ok yes sweet link but my trouble is when loading the linuxcnc machine, somehow the arduino driver is not loading properly
"Waiting for component 'arduino' to become ready."
Which Arduino driver?
mevon_, oh - I had looked at that.... That seems a bit scary... It seems to try to replace the printer port with usb arduino... I don't think that would work very well...

[20:18:22] <skunkworks> http://emc2arduino.wordpress.com/2012/04/09/emc2arduino-0-07a-hits-pre-release/
yes exactly that
I bet its the same arduino.py
Ive edited it to change to /dev/ttyUSB0
when loading i get this "HAL: ERROR: pin 'motion.probe-input' not found mantis.hal:47: unlink failed"
Comment out the line in the custom.hal which is trying to unlink a pin you haven't linked.
mantis.hal would be the custom.hal in ArduinoEMC .07b
[20:21:34] -!- wboykinm has quit [Remote host closed the connection]
I don't know, I guessed that mantis.hal was your original HAL?
well actually custom.hal from ArduinoEMC .zip
OK, does line 47 in mantis.hal try to unlink a pin that isn;t linked?
i guess so too but since its in a driver i was guessing it could be virtual
as in HAL virtual
where these pins would of be set before that?
kinda annoying that the ones i find (RM2ZZ) that is dual race bearings is 3/8" hole ... :/
I have no idea what you are going on about.
i guess its not a big problem tho, even tho stuff arent metric all that need to be 3/8" is the cam action bushing for them
andypugh, i ran the stepconf wiz and the first hal it gave me was for parralel port
Line 47 of your mantis.hal file says "unlinkp motion.probe-input" I can tell that without even seeing the file.
I don't know why it says that, I don't know how it came to say that, but it does.
i swapt that one with the custom.hal i received with the arduinoemc 0.7b .zip
delete that line, and see what crtashes next.
You made a grave mistake then.
You need your original HAL file _and_ the custom.hal file.
HAL: ERROR: pin 'motion.probe-input' not found
mantis.hal:47: unlink failed
ok got that
gonna try with both
So ignore my comment about deleting the line, reinstate the orignal mantis.hal file. Then leave custom.hal called custom.hal
[20:27:51] -!- holst has quit [Quit: Leaving]
but custom.hal your talking about is the one generated by stepconf or the one in the arduinoemc?
For some reason I cant quite follow the writer of that Arduino thing has decided to create a custom.hal to patch a generic stepconf setup.
So you want your original mantis.hal and his custom.hal
well I couldnt really generate a machine that wasnt parrallel port
Stepconf is for the weak!
It would be neater to hand-edit his custom.hal changes into your HAL file, but then stepconf will over-write everything if you run it again.
i now can load it without error but manual control is grayed out
You might need to turn the machine on
(f1 then f2, or the red buttons at the top of the screen)
im so noob :P
it took me a few minutes the first time too
interface works but nothing moves :(
Any action from the Arduino?
machine->show hal config
Look under "pins" do you see any arduino pins?
You should see things like arduino.stop, arduino.probe
If those are not there then my guess would be that your iNI is not referencing the custom.hal
i see the pins
somehow the have a status
[20:38:15] -!- psha has quit [Quit: Lost terminal]
That's a good sign.
sry im so amazed right now :S
linuxcnc is a beautifull machine
Have you loaded the Arduino sketch into the Arduino?
yes i had to make a lot of changes in there but nothing on the comm protocol
stepping time is just a little longer
can EMC do good threading with only a index input?
for lathe single point threading
I am rather puzzled as to how they expect to get around the USB latency. Generally USB isn't useful because it can take a couple of mS to send data.
Depends on spindle intertia vs cutting force stability
results are obviously worse than with a full encoder. define good.
Aero-Tec: Better than Mach. :-)
[20:41:22] -!- zzolo has quit [Quit: zzolo]
better then mach
andypugh: who's they?
why do you think you want to use that setup?
ok so single index is better then mach
it is what I have setup right now
I was doing threads with mach
I would guess about the same (both would have to guess the spindle position for a whole turn )
stepping 3axis at the same time takes me 800 us minimum
but will need to do them soon with EMC
pcw_home: Yes, but AFAIK mach doesn't look at the spindle again once it has started the move. It guesses a speed and sticks to it.
it is a large lathe and small inside thread
andypugh: Oh thats terrible
Aero-Tec: You need to make sure you link the position-interpolated pin in HAL, not the position pin.
Otherwise LinuxCNC will be worse than Mach, as it will see a spindle that moves in single-rev jerks, and try to match that motion...
I have had good luck with mach threading as my lath is big and chuck heavy, but your right as to mach using index to start and not during the threading as far as I know
If you are using external buffered controllers (like that Arduino) then you don't have much choice unless there is threading code in the controller.
the index encoder goes into mach/EMC now
through a Pport
want to upgrade that soon
mevon_: Conventional wisdom in LinuxCNC land is that USB simply can't work. I will be interested to see how you get on. I suspect that it might be possible to make it work by sending timestamps and correcting internally.
even a few slots will make a big improvement in following (1/2 wheel and 2 pickups at 90 degrees = 4 counts)
4 count encoder has the advantage that A=Z
and put a proper encoder on for threading and rigid taping
4 counts should be about 16 time better than 1
but you need a index
you can not just use a 4 count encoder
A=index with a 4 count encoder
andypugh, thanks for your support
what's a polar bear?
I can easily make the encoder 4 count
a carthesian bear which underwent a coordinate transformation
its just a 1/2 disk
but you need index do you not?
Aero-Tec: you do need index for threading
alex_joni: And a sheared sheep has undergone an affine transformation?
2 wires = ABZ
thanks for all the help you guys have been
how can 2 wires do AB and Z?
I can see 3 wires
andypugh, I kinda messed and the mantis.hal generated by stepconf wiz was overwritten, somehow in the ini Im loading two times the same file with a diff name and it works :S
One wire does A and Z
ie, the A and Z signals are identical, but LinuxCNC does different things with them.
I keep meaning to add missing-tooth index to the encoder.
that should be easy at speed (and impossible when jittering around)
That's what cars used for crank timing for years, and there are lots of neat magnetic encoders and hall detectors for them. (and, being made in the millions, they are fairly cheap, and have a crank-shaft sized through hole, so good for a lathe.
pcw_home: Aye but then you don't _want_ to index unless the spindle is moving at a decent speed.
someone knows where i could find the 9axis simulator .hal file?
A should switch several times per rpm, index only one time so how do you use 1 wire for both A and Z?
In the config-picker. sim->axis->axis-9-axis I think
Heres a hint: a 4 count/turn encoder is a 1PPR encoder
Aero-Tec: PCW might not have completely explained You need a semi-circular encoder disc and two sensors at 90 degrees.
now that makes sense
So one rev is A+Z+ B+ A-Z- B-. That's 4 AB counts and one rising edge on Z.
I have this picture in my head, I dont know why you cant see it
you would want fairly accurate 90 degree sensor placement
Aero-Tec: What drives your spindle? You could use a single channel and counter mode on a gear or a toothed pulley.
is that good enough for rigid taping?
Aero-Tec: I would say not.
It is going to do badly at spotting the reversal point.
Yeah for tapping you probably want a much higher res encoder
Worst-case it could be out by a quarter-pitch, and that sounds bad.
V belt but have gears that turn with the spindle so I could do a magnetic encoder
and the following few pictures
it is a big lathe
You might spot that there are two versions. First a 180 degree quadrature encoder, then a more conventional 90 degree one :-)
Yeah a couple biased hall effect sensors with 1/4 tooth spacing offset would do
well 180 is 1/2 of a differential encoder
Aero-Tec: These appear to be the only suitable sensor (unless you add your own magents to normal hall sensors). http://www.ebay.com/itm/ATS667-ATS667LSG-ATS667LSGTN-T-Gear-Tooth-Sensor-IC-/110725022530?ssPageName=ADME:L:OC:GB:3160
pcw_home: Have you ever seen any alternatives?

Im just wondering how kinuxcnc is working with the switches
is it in the ini file?
[21:24:58] -!- AndroUser [AndroUserfirstname.lastname@example.org] has joined #linuxcnc
If you tried a real machine with simulated switches it would just move in one direction for a fixed length of time until the simulated limit switch component triggered. Then it would call whatever random position is was in "home". You are better with no home switches than simulated ones.
[21:25:13] -!- AndroUser [AndroUseremail@example.com] has parted #linuxcnc
andy ok got it
[21:25:36] -!- AndroUser [AndroUserfirstname.lastname@example.org] has joined #linuxcnc
HOME_IGNORE_LIMITS is for ignoring limit switches when homing. This lets you use one pin for all limits and all homes on all axes.
(But does mean you can only home one axis at a time)
ok ok i have limit switches physicly connected to the arduino
the thing is, the arduino sketch only checks for limits before sending a jog to() command
i find it odd how its implemented
but it seems to only send feedback when the state of the switches change
MLX90217 (and your own magnet)
i wanted to implement software limits so i could go to my limits
without overstepping them
simulated ones seemed nice but since the dimensions are set in the ini file, i bet emc wouldnt go over those right^
ok in the vid they had per fetching tool changes
You would just confuse LinuxCNC.
how did they do that?
the tools will move around on the tool chain
mevon_: Just mark some lines on the machine, jog there, then press the home button. (that makes your eyes into home switches, in effect).
code rings on the tool holders
so you would have to update the tool table for each tool change would you not?
ok thannks for the advice this is really helpful to me
Aero-Tec: LinuxCNC can be configured to pre-fetch the tool on the T command, and do the change on the M6. So you put a T for the next tool immediately after a toolchange.
code rings on the tool holder?
That is how the machine knows which tool is about to enter the tool change position.
ok but how does EMC keep track of where the tools are on the chain?
andypugh, would you think this would be useful? HALFILE = axis_manualtoolchange.hal
mevon_: If you have changeable tools, then yes
I do to make diff hole sizes
Though you will see there is not much in that file, and you can combine it with the main HAL file. (Stepconf probably already put it in there)
I can see the fist time the tool is used, but each time a tool is used it is moved on the tool chain to a new location
Since they are all labeled LinucCNC need not keep track of where they are
your joking right?
how does it read the tool
No, there are mechanical bar-codes on the tools.
and how do you set up EMC to read the tool?
And an array of microswitches that watch them go past.
Howeverâ€¦. That's not the usual way to do it. LinuxCNC can remember where in a carousel it put a tool, and can go there for it next time it wants it. skunkworks has a very unusual machine. It's probably one of the oldest CNC machines still running.
there sure are some very cool EMC controlled CNCs
one has to be impressed by it all
I would hazard a guess that the K&T toolchanger uses something like: http://www.linuxcnc.org/docs/html/man/man9/match8.9.html
acutally do it in ladder
&1 - &2 - &4 - &8 and so on
[21:40:15] -!- mattions has quit [Quit: Leaving]
I ought to try ladder, but I have so far not seen the need.
I did the tool chain/changer in ladder - the spindle gearbox in comp...
You should use APL code somewhere, just to match the age of the machine.
so why not use EMCs way of being able to keep track of tools? why do tool encoding?
because it works as is.. There is no way to know what pocket is where in the current scheme
That was what the machine was built with. I suspect that the machine has no feedback of absolute chain position, just what tool last went past.
also if EMC is tracking tools in the changes, does it keep tack of the new tool locations after a reboot of EMC?
doesn't need to
on yours no as the tool is labeled
[21:45:02] -!- Yarl has quit [Ping timeout: 260 seconds]
I call for tool 4898 and it runs the chain around scanning for one that matches that number.
barcode or something ?
but for some machines, like mine, yes it does keep track
but if EMC was tracking the tools through each tool change, is the new location of the tool recoded so if you have a power outage or what ever, the new tool locations are remembered?
yes the tool table always contains the current tool<->pocket mapping

so what does a mechanical bar code look like, and can you make your own tool holder labels or are you stuck with finding old holders made for that machine?

andypugh, so basicly i shouldnt be unliking in my .hal things that havent been linked before
and linking them there should be the first time it was linked right?
one way to set up a single encoder with index is to have the index slot larger then the other slots
that was how mach was supposed to work
I even cut the encoder disk for that
[21:57:01] -!- DJ9DJ has quit [Quit: byte]
but then found out that mach did not finish setting that up so had to block off 3 slots
you have 4 slots in the disk but one is larger then the rest
the index one is the larger one
not sure if that could be done with EMC or not
Andy volunteered to add the feature to the encoder comp :-)
[21:59:17] -!- kmiyashiro has quit [Ping timeout: 255 seconds]
if that could be done with EMC then my encoder disk is ready to go, just have to unblock the 3 slots
as long as its for threading, it should be OK not sure how well that will do with quadrature or reversals
[22:02:15] -!- chillly has quit [Quit: Leaving]
true it would not give direction, but would give good spindle speeds during threading
[22:06:18] -!- FinboySlick has quit [Quit: Leaving.]
BTW, how I am sure that Mach only looks at the index at the start of the threading run is I had a encoder problem that made the indicated speeds erratic, and Mach would cut the whole thread at the start speed no matter how much it changed during the thread run
how wide are the slots" LinuxCNCs width sensing resolution would depend on the base thread and spindle RPM and slot width (% of circumference)
mevon_: Yes. Basically that custom.hal provided with the arduino driver is doing a lot of rewiring.
the index was 2 times the other ones if mem serves me
I guess the ideal would be 25% slot 75% blocked except index which would be 50%
my slots are smaller then that
anyone here know if one of these http://www.ebay.com/itm/New-Portable-Storage-Food-Bags-Heat-Handheld-Instant-Sealer-Instant-Food-/310362516805?pt=LH_DefaultDomain_0&hash=item48430c2d45

thanks andy, I learn fast when explained for a long time :PP
would be nice to use the whole encoder
pink bags probably
Aero-Tec, what about those silver bags like HDD's ship in
i don't seal em, just fold em over
what about them?
how fast do you thread?
k for about $3 worth a test
i'd think so
will have to check
lwizardl if you're gonna do that you should check on getting the bags in a roll
we seal em closed with a label

in the us?
uline has alot of shipper supplies
Tom_itx, yeah looking at those from a few shipping companies like uline
i get my padded envelopes from them

so would it be easy to set up EMC to use my encoder?

no, you can always just run the updates to get it
but, it is 2.5 now, not 2.4?
it keeps asking me if i want to update the OS
my old livecd + updates is fine then?
if it's 2.5
320, 470, 690
would be one of them
I shoudl have spent $10 more on the case, this PSU looks like crap
depending on what I am cutting
Aero-Tec: how fast is you base thread?
not sure what you asking with base thread
in your .ini file
what is a base thread?
25K if IIR
can get the specs of the encoder disk as well
in the INI the base period is 25000
not sure what unit is used
how can one tell?
andypugh, Ive commented out the unlinks and I get this error now "custom.hal:85: Pin 'axis.0.neg-lim-sw-in' does not exist"
OK 40 KHz so at 690 RPM you have about 3500 sample points per turn
so you have to have enough sample points during the slots
to reliably detect the difference in the slots

I have silver ducting tape blocking the slots
no good for for tapping however
would be cool to use it like it was designed
but would be better single point threading right?
with mach I had to do a whack of finishing passes to get the thread to be good enough
Yes should be (but still need mods to the encoder comp to work)
and some time I would see it take a bite that was to big
basically Andy's missing tooth index
so whats my next step to set this up?
I am still very new to all this
I would really like to have active tracking during the threading
and to have more then just index would be great
The easiest thing is probably to add an index sensor/deeper slot
Other wise you have to wait for someone to get interested enough to write the code
would be easier to add the gear tooth sensor
but thanks for your interest in this
how hard is it to learn programming EMC?
I have written programs
gear tooth sensor would be higher resolution as well
is there a programming manual for how to program EMC?
yes and I can do quadrature with it so rigid tapping as well
Not really but for this level (Hal Components) I would just look at the existing ones for guidance
yes you can do quadrature with 2 sensors a say 2 1/4 tooth pitch apart
(N+ 1/4)*tooth_pitch apart
