I'd like to get inkscape to export dxf files with arcs.
I found a script to export dxfs, but it converts all splines and curves to line segments
I have a file "biarc.py" that puts out gcode, written by jepler it says...
skunkworks: that last 1/10 of a wall is just really holding out on you
about 60 inches :)
mozmck: Don't trust InkScape to do perfect math.
math for what?
converting the splines to biarcs?
I think the math would be done in the extension...
emc2 trunk has gcodes for splines and nurbs
it is extremely new and lightly tested
I saw that! I'd like to play with it as well.
right now I would like to get something out of inkscape that I can use a cam program (probably sheetcam) to convert to gcode.
I think sheetcam only loads dxfs?
yes, and gerber i think
dxfs (like gcode) are lines and arcs - not sure how to get that out of inkscape.
I found an extension for inkscape to export dxf, but it converts splines to line segments
I'd like to at least update that to convert the splines to biarcs.
or the spline gcodes!
I'm trying to learn python first...
if you want to be on the bleeding edge, that is
That would probably be next.
There are quite a few people using Corel Draw and sheetcam in windows for making designs to cut with plasma or on router tables.
corel has the same problem with dxf export (lots of line segments), so there is an extension for corel that you can buy to export dxf files with arcs
it would be quite handy to a lot of folks if inkscape could do the same thing
yes sounds like...
unfortunately it will probably be at least a year before the version of emc2 with splines/nurbs is release quality.
if not for that, I'd suggest that's the way to approach it.
yeah, and I'd really like to play with that too. but it's one thing at a time for me. I'm *way* too busy!
always short on time - story of our lives.
with that in mind, I should go to bed! goodnight.
yup, and too much to learn. nite
if you have current limiting with pwm .. at 20kHz, how does that work with stepping frequency of 350KHz ? .. then theres no time for any current limiting is it? :P
MrSunshine_, you will never step at that speed, stepper motors have a maximum step rate
MrSunshine_, read some specification data
ahh ok :)
i was looking at the gecko drives they can step up to 350khz some of them
no thats microstepping not the real rrate the motor sees
hm.. roller screws why do you never hear about them anywhere? :)
are they good ? .. bad? .. etc? :=)
hello, i have a cnc that the x axis and the y axis is not perfectly 90 degrees, i have calculated a transform matrix to compensate this, and i don't know if it is possible to assign it directly to emc instead of aplying the filter to every gcode file
yes the machine can compensate to an extent
and where must i put this matrix in emc?
is a 3x3 matrix to multiply to the 3 target coordinates
so x=a*x' + b*y' + c*z' -- y=d*x'+e*y'+f*z' , etc
so i have a,b,c,d,e,f,g,h,i
I was thinking of the screw compensation.
no, is for compensate in software
because i cannot calibrate the machine
you need to add something to the kins to suit your machine
see the stuff stuart did for his 5 axis to correct it
has he a webpage?
he posted details to the mailing lists
upss, i didn't know there is a mailing list for emc, i'm going to subscribe, thx

* archivist of out to look at a mill
errhhh i need 2 hours
can one use the mesa brushless cards with EMC
it looks like they need to run with softDMC
at the moment, there's no specific support for them in EMC
dang, cos i were thinkin these might be nice http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=5142&Product_Name=HXT_80-100-B_130Kv_Brushless_Outrunner_(eq:_70-55)
I think the phase currents need to be updated more often than the 1KHz servo period, so it's likely that it would take a significant amount of work to use them with EMC
if it can be done at all
softDMC supports it *sob*
well, it could be possible to put the right signal generator into the FPGA, with a velocity register being the only thing that EMC has to update
I believe they are around an 8 pole motor so at top speed its commutating at 800Hz
or even to make emc work with SoftDMC in some dumb mode
those both sound rather non trivial though
I do like the idea of EMC + softDMC though
just in general
800 Hz commutation for a sine wave means much higher than 800 Hz waveform updates
more like 80 kHz or more
nah nothing like that
100 updates per full cycle seems reasonable
maybe less would work. I don't know
you only need 4 or 5
that's doable with EMC
you can go to around 8-10 kHz updates I believe, depending on the PC
and the PCI chipset - some of them are dogs
80Khz is much much faster than the actual PWM frequency they use so your not going to see much benifit to that
most of the available controllers run ~3khz PWM freq
I'd be surprised at that
gecko drives are 20 kHz
I have them and use them
these are hobby things
you can hear it and its 3khz
same pitch as the other motor controller boards i repair
the geckos are industrial drives, they just sell to hobbyists also
are you saying that Geckos are 3KHz?
no the hobby ones
ok, so you're talking about hobby boards when you say "available controlllers" ??
nfi what geckos are other than its probably an inaudible frequency because a 1Kw motor with 3Khz PWM would wine like a bitch
[13:05:11] <SWPadnos> http://www.geckodrive.com/
mesa have a controller for it that runs like the other ones at whatever you want it to
up to 50
the controllers i have used on those motors are 3khz hobby controllers
I am somewhat suprised that the mesa card actually is using the host to provide the PWM but i guess if they have the FPGA there it makes sense to
the host doesn't do the PWm
and just pass the comutation signals back to the host (or perhaps use the encoder)
it sets the PWM duty cycle
sorry the mesa driver card uses the controller card in the computer to do the PWM
and the SoftDMC controller (in the FPGA) does the commutation work
from the driver cards POV its "host" is the controller card ;->
well, it makes sense when you consider that the driver is a peripheral for the FPGA card
it's not intended to be a standalone driver, it's meant to be a form of I/O for the FPGA
like i said "but i guess if they have the FPGA there it makes sense to"
needs to be rewound for a higher voltage to really work for a servo system
the current limit on controllers for this stuff, is that the supply current limit or the motor current limit/
should be motor limit
I like the price for those http://kelinginc.net/ServoMotors.html
motors but i cant find a 40A controller for them
you don't need a 40a controller. Didn't we discuss that before? ;)
that is probably like a 2 second peak current.
before the thing demagnetizes
its continuous current is 7.8A
right so i can put 40A through a 20A controller and still get the peak torqe
and no smoke
If you are never sposed to use the motor beyond the continious ratings what is the point of the peak rating?
the continuous rating is just that - the max you can use for ever and ever without the motor overheating
continuous ratings are usually heat based
maximum ratings are the most you can ever do to the motor, and may be based on heat in addition to other factors, such as wire gauge or demagnetization
so why should i get a controller that cant use all of the motor?
ok, so the continuous rating is useful, in case you're making an escalator or somethng, right
the motor will run and run and run, as long as you don't go over that continuous rating
I have actually built several electric motors, so i am somewhat aware of peak and continuous ratings.
in the CNC world, motors are rarely used at their peak performance, but it is sometimes desirable to use them above the continuous ratings
like say when you wish to accelerate the table in a paticular direction
[13:22:49] <skunkworks> http://www.a-m-c.com/download/datasheet/100a40.pdf
skunkworks do i want to know the price on these?
they're a couple hundred dollars each I think
and sometimes available on eBay
I would guess around 300-500
I have 6 of the 80V/30A units (from ebay)
I was liking the mesa 2 channel 20A 150 volt controlers
Valen1 is now known as Valen2
Valen2 is now known as Valen1
for $300 a pop
so ~$150 a chan
they seem to provide alot of bang for your buck
look here as well: http://pico-systems.com/motion.html
similar power ratings though, 160V/20A
and he's got a brushless drive with the same ratings, both are $150 or less
yeah i just noticed that one
I like the mesa keeping it digital thing
For a cnc machine... lets say you set your accelleration to take 20a. (of the 40a peak) - now you when you are running the table it accellerates for a second and run at your feedrate for a while then de-accelerates for a second. (not a problem) now lets say you are contouring a part? You are constantly acc/decel - much more than 1 or 2 seconds.
skunkworks: yes but when you are contouring you will also typically be running at a much lower speed
speed and accel are mostly indepedent variables
that's why servos are so great
if the speed is lower then you need less acceleration to get to that speed
if you're always changing speed, then the accel will be high all the time
it depends on how fast you need to change speed
if the average speed is low then the average acceleration will be low
Valen1: pico-systems are also pwm input
(in comparison to doing the same profile at a max traverse speed)
so a raster-like milling process will be bad for Z (since it's got to move up and down all the time), not bad for Y (since it just goes at one speed all the time), and very lightweight on X (since it just moves over every once in a while)
yes i was noticing that
assuming an X-Y raster :)
yes and the acceleration you see on Z is dependant on the speed of Y
no, it's not
if you run Y slowly then the acceleration you need to follow the profile is less than if you run y fast
lets say i want to machine a sine wave on your raster machine
if you set a max accel (in EMC), then that accel will be used all the time, unless there is another joint being accelerated which limits the accel on "this" joint (to follow the correct contour)
the acceleration used to go from 0 to 1 inch/sec is the same as the acceleration used to go from 0 to 2 inch/sec; it just doesn't accelerate for as long.
yes but if your cutting metal then you are going to be moving slower than if you moving the head around
acceleration is NOT proportional to velocity
Valen1, sure. are you trying to get max current so you can accelerate to rapid speed twice as fast?
if you're not going to be using max during cutting (most of the time), then the only use is rapid accel (not rapid speed, just accel)
ok. if that's so important to you, knock yourself out :)
it just bugs me to have really mismatched components
I would argue that they're not mismatched
if the servo drive is capable of outputting more than the continuous current, and up to the max current, then they are a good match
the controller maxes out before reaching half of the motor capabilities
if your application requires a higher percentage of max than the driver will provide, then the driver is a bad match for your application, but not for the motor
thats the thing, most servo drives seem to be able to do 20A, and even the controllers on the site they sell don't do 40
It seems to me odd to sell a 40A max motor and a 20A max drive for it
you'll never smoke a motor with their drive :)

Is there a wiki or something with all these suppliers on it?
yes, the emc wiki has a list of compatible hardware
the EMC wiki seems to be a little light or at least the suppliers sites seem to be weak
I think there's a partial list of motor drives too, but it's certainly not complete
[13:39:36] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware
yeah that doesent mention an of the suppliers that have been mentioned here lol
in their step and direction drives
that page is probably complete with respect to the smart I/O boards, and less complete with respect to anything else
step and direction drives are yecky.
they lump servo drives into the same category
[13:42:43] <Valen1> http://www.granitedevices.fi/index.php?q=brushless-servomotors
isn't looking too bad
$315 australian per motor
ahh, rather low on the peak torque
not too bad on the cont torque though
Valen1: based on vsd-e_manual.pdf sections 8.7 and 12.4, their amps will probably work well with pwm or analog outputs of mesa or pico I/O cards
[13:49:55] <jepler> http://www.granitedevices.fi/assets/files/vsd-e_manual.pdf
vsd running motors in torque or velocity mode
interesting, the datasheet says they can run "stepper" motors in servo mode
theres no real difference between the 2 really
it is what gecko is trying to build (stepper servo)
shouldn't be too hard to do, you just need to run at a decent speed and have feedback on rotor position
seems like everyone tries it but nobody is using it
I wonder if they can use the encoder to do that without too much hassle
I think Mariss opted to redo the servo drives with CPLDs first, and he'll be back on the "unstallable stepper" drive once the G380 is done
its the feedback thats the hard part, because the rotor position is a variable, you need to know it for commutation
well, all the flavors of the G380 that is
mesa doesn't seem to have a price on their 8I20 2200W 3 Phase Amplifier
with mach, I don't see how it can do better than his step-servo drives in the case of a following error -- i.e., just fault, and you've still lost position
I agree - it's only really useful if you havea controller that can reduce speed on all joints when one is load-limited
Valen1: I agree, I don't see it on the pricelist either. I recommend e-mail
I probably don't want to know lol
cant run it with EMC anyway probably
(I am not sure whether the 8i20 will work with hostmot2 today; I see it requires input of reference angle, and I don't think that's any of the current hostmot2 modes)
it has hall sensor inputs
and i think i see a micro or 2 on it
"The host controller may be a PC with a fast serial interface and quadrature counters or a Mesa FPGA card running SoftDMC or HostMot2 firmware."
oh i see what you mean
it wants torque inputs
they mention an 8C20 to make it into a "smart" controller but that also isn't mentionend anywhere else on that page
pcw or seb are who you want to talk to, but it looks like neither of them are here right now
its probably a mega $ product
and then you need motors to attach to it

Yeah, I'm that guy. For python I have used numpy, but I'm working on a c++ version. I need some simple matrix operations functions for the optimization routine.
boost should be a good library, but I understand it's a little slow in the matrix department
numarray/numpy do all their dirty work at C speed
Jon_geo01005, they're complex to look at, but I bet the boost libraries are about the best you can get
in terms of correctness and documentation at least
Too late for Valen but:
8I20 price should be on website...
8I20 by itself is dumb

It needs reference angle and desired torque from host

No, RS-485 serial

I have only liquified some mosfets - no bang yet.
It was fun, though I hate high voltages (too many bad memories from tube days)
At low voltages MOSFETS are almost unkillable
once you get above 100V they are a lot more fragile
you dont have the luxury of the extremely high peak
current capability of low voltage -low on resistance
the metal back of the mosfet oozed around the heatsink
looked like someone tried to solder the mosfet to the heatsink ;)
ah... dont need any heatsink compound... mold them right on
I have been having very good luck with the igbt's I am playing with.
very little heat and they switch fast enough for me.
plus they just feel solid. :) They should - they are made by irf - the experts ;)
MOSFETS are still more efficient around 200V (lower on voltage and switching time)
but above that IGBTs are often a better choice, especially if you have relatively low switching speeds
these seem to handle 20khz just fine
The mosfets I started with just had too high of Rds. (.12 iirc)
20 KHz is a close to the limit for small IGBTs, (the 8I20 module runs at 20KHz)
On our 7I29 we use 26 mOhm Rds MOSFETS
Yes - .12ohms. The igbt's I am using are these. http://www.irf.com/product-info/datasheets/data/irg4pf50wd.pdf
(got a really good deal on them)
Thats a very fast IGBT, but still at 20A you have 40W per transisitor to dissipate
One nice thing about IGBTs is the low reverse transfer capacitance
avoids the more and more exotic MOSFET gate drive circuitry
to avoid DVDT turnon

No, but it was < 5 usec
wow - this thing runing a single core kernel runs around 17us
he probably didn't stress test it too well :)
there were some general improvements with cradeks experimental SMP kernel
I think it's limited to 2 cores though, so disable HT if you want to try it on the atom
I find a custom kernel gives you some small speedups
that's the kernel that I got sub-2000 numbers on after optimizing startup scripts

eric_unterhausen, that's my impression as well, though it appears it works pretty well in the Atom
how do you optimize startup scripts?

pcw, dunno. this is the same machine that I did the custom 5i22 thing on a year or so ago
A chipset with Enet in northbridge or PCIE Enet should fix that
the chipset is particularly crappy for reads - it doesn't combine reads ever
eric_unterhausen, knee handle is nearly unusable
this is the Intel ICH7 (same one used for just about all atom boards)
I think it has integrated ethernet
If you enable read-ahead in PLX9030, you may be able to do better
archivist: is that a really tiny motor on the coolant pump, or is the mill larger than it looks
small coolant motor
(watch out for things with read-side effects)
did that, didn't help :)
the chipset docs actually say that the chipset will not do read combining
write combining maybe, reads no
Well then use DMA...
9054 has nice DMA controller
Eventually HostMot2 should support DMA
yeah. I just never got to that point with that project
and it works, so I'm not changing it :)
Its actually pretty easy
I think its takes about 6 setup writes
and the blam
maybe 2 more writes to repeat
blam - your data is transferred at the PCI bus clock rate
or something like that
I thought there was an issue with emc2 using dma

so they're down to $25k? :)
or is it 35k
I had an offer for a Haas that is 2 years old for 14k
oh, that's "not bad"
(for some values of bad)
24x 16y 16z
ebay and get some hmc or vmc that is in need of a new controller. <10k
I'd like to find a lathe that needs a new controller...
that is acutally a production machine. maybe even tool changer and pallets
SWPadnos: I really doubt the tormach can cut as well as my series 1 bp
series 1 manual
not necessarily the CNCs
oh ok, mayyybe
they're pretty rigid for their size
you couldn't cut as large a piece as quickly as a BP, but for smaller workpieces, you can remove just about the same amount of metal per hout
maybe (1.5hp vs 2hp)
actually, my series 1 is 1.5 HP
don't know if they're the same ... hp
and they made 1HP as well
huh, 500lb workpiece, they say
most people will tell you that it's the rigidity of the machine though, even at those relatively low spindle powers
I think it's 1000 for a BP
if you have strong arms for the knee ;)
ok, I sit somewhat-corrected, it's more machine than I thought.
Dewalt Knee Adjustment kit
it's pretty surprising to see it cutting at high load
this came out nice http://imagebin.ca/view/UMi_sm.html
when I was there, they were testing their super-duper insert cutter

doing 50IPM passes with 0.1" depth and 1.5" width, IIRC
BJT-Work: what machine is that? (mill)
BP series 1
looks like a terrific finish
hmmm. that must be wrong. maybe it was 0.2" depth or something. my brain is failing
I had to stop in the middle and sharpen the cutter :/
ew your lucky those puny clamps dont come loose and spoil the show
only took 0.025" DOC
pretty sure I would have used a boring head... how round does it have to be?
or will you finish it up that way?
it is finished
wow - this is relitivly close. http://cgi.ebay.com/1987-Matsuura-MC-510V-CNC-Machining-Center_W0QQitemZ260401650240QQcmdZViewItemQQptZBI_Mills?hash=item260401650240&_trksid=p3286.c0.m14&_trkparms=72%3A1205%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A0%7C293%3A1%7C294%3A50
tractor part not that precise
just a bronze bearing pressed in and the axle part you saw yesterday fits in there
for sure on a roller bearing I would use the boring head
talk to you guys later time to put parts back on the tractor :)
we await the assembled fergy pic
I'm tired of waiting LOL
I should take a pic of it scattered out on the garage floor :)
kit with many spare parts now
thats how some clocks get delivered here...more fun
talk to you guys later
what are people doing to sheild monitors from chips in the shop?
