* Skullworks_PGAB slaps skunkworks with a big red brick
Skullworks_PGAB: out of trouts ?
naw - bricks just hit harder
trout I can eat
Skullworks_PGAB: if you can cause the trout to swing sideways as you slap someone with it you should be able to hit someone harder with a trout :D
I was just hoping to follow up on some info he sent me earlier
that soulds like it might take practice...
did you completely give up on the pluto now that you have a mesa?
no - I will probably use the pluto for testing
then maybe it will be used for a lathe
also how does the pwm-pwm work vrs pwm/dir?
pwm/dir I understand
2 pwm signals are output - one for cw and one for ccw. instad of 1 pwm and one direction pin. same final result
OK - I get that
things could get messy if the borad received pwm on both at he same time I guess.
this is almost the same as the UHU power stage.
not really. if both are in effect on - or off - the motor goes into breaking. (both upper or lower mosfets off)
did you ever write down what the inputs/outputs were for the pads?
* Skullworks_PGAB feels like he is holding pages 2 and 3 of 5.
I have eagle - I have never USED eagle...
I can see the diagram, and placement. but defining layers for post processing is out of my league at the moment.
I need to dig up so good tutorials for eagle if such exist
eagle site has a few.
It take a bit to get used to - it is 'odd'
raw G-code would be simpler - I can import and repost that very quickly.
I'm going in circles now it seems - can't finalize the ballscrew design without knowing which motors I'm going to use.
can't finalize motors until I have servo amp and power supply locked in
98.5% of the time I just wing it
* Skullworks_PGAB is not afraid of majic smoke...
but I am getting to the point of ditching the whole servo idea and just using steppers.
use a FAST EAS 2 axis bipolar for x/y and a gecko 203 for z and drive them via a USC
use the ABBA ballscrews and kit from CNCFusion
Skullworks_PGAB: instructables has some reasonable eagle tutorials, google has a few more
I'm going to upload a sample vid of the same base machine that another user mounted Nema 23 servos direct drive.
[03:01:43] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo_Mill.mov
I had hopes of getting somewhere close to this...
is that real time motion?
cool, the 2nd half sounds like grinding
can do 400 IPM - but he has the vel limit turned down - it scares him too much running parts
the grinding is the cheap single nook ball nut on each screw
those rolled screws are crap for milling
the rockford precision are much better but still make some grinding noise in the ball return tubes
if he used double nuts you would not hear as much - and I think he did add them after finding he had .003" backlash.
but that is the size of the iron - a grizzly labeled SEIG X3
the ABBA screws with 4 circuit ball nuts are sweet - but pricey
zero backlash as preloaded from factory.
US made ballscrews have this huge gap.
are they sending production to China?
both Nook and Rockford make "T"ransport grade screws, and rockford has a precision grade rolled screw...
but there is nothing avail between that and the high end ground screws
nothing US made
Hiwin and ABBA have an ultra precision rolled stainless screw and much better ball nuts.
ihave abba rails on my machine
Hiwin also sells the ground screws for not too much more.
ultra precision =.0005"/ft error
I only have 16" x
No - not to china - just a huge gap in the product lines
Rockford only makes rolled screws. The basic transport grade has an error of .005" /ft - but the specs on pitch dia are the real killer
it is possible to get a nut at MaxMC and a screw at MinMC that leaves you with .025" slop!
and technically both are in spec

aw that's so cute.
where could i get permission to merge a part of the EMC documentation on wikipedia ?
could anyone help ?
the current EMC entry on wikipedia leads to a blank page ...
who should I ask ??
just a thought, since demoorphic was asking for permission, would it not be sensible to release all the content on the website/wiki under Creative Commons and put a banner on the page
or rather a small logo (I hate banners)
Skullworks_PGAB: why are you considering skipping ser`vos?
how much torque can you normally handle with steppers before needing servo's?
iv got a manual machine im thinking of converting once iv finished setting up my cnc machine with emc
I don't think it's a question of how much torque, I would rather say it's a question of how much torque at what speed
wondering if i need teh expense of servo's
depends on machine size table weight..
and foremost budget..
it probably doesnt need that much speed i guess
looking at getting a horizontal mill if it goes for the right price
looks like it has more space available for a 5 axis if i ever feel the urge
the main problem is probably spindle speed..
though that's the same on all homebrew machines :)
there are a couple of nifty boards out there though that make it pretty easy
the spindle i can deal with on an on/off basis for the most part
just set the speed manually
[10:34:17] <Rugludallur> http://www.campbelldesigns.com/Combo-board.php
That's a breakout board with built in spindle speed control
gonna have to sort out a spindle control for my lathe
huge 3 phase thing
looks like a motor from a train
feoc: might not be possible to use the motor and get speed control, is it a variable speed motor as it is or do you just use gears ?
on the lathe its a variable speed motor
its already a CNC machine
feoc: ahh ok :D
so ill have to buy a proper spindle drive i reckon
feoc: you can probably pick up a VFD on ebay cheap
feoc: Variable Frequency Drive
feoc: AC converted to DC, and then converted back to stepped AC with a variable frequency
ill have to have a look
im heading down the workshop now anyway
its got a spindle drive in it but i dont know if it works or not
prolly be easyer to sell all that with the siemens controls
and buy nice new stuff
oh, I meant the biggest problem is low rpm small cutters..
so you never utilize the speed if your machine
I'm starting some ui-ish thing soon I think..
work on one
pyqt looks like a good option..
then I can use the designer.
and then I can also use the NML/HAL stuff
anonimasu: ui-ish,, what you making ?
Rugludallur: something that looks like a real user interface.. on a commercial controller..
Rugludallur: that can be operated by panelmount buttons..
for coworkers or you going into business ?
no, for myself..
anonimasu: ok :D
axis is nice and all but it requres too much mouse/kb movement to get stuff done..
anonimasu: if you are looking at something a bit faster and more to the point tkemc is that
I dont like tkemc..
Rugludallur: it should act like a real control(the ui) also..
anonimasu: ok, I'm not sure I understand what that means :) If you are just talking about emulating an embedded system it's not something I would do
Rugludallur: why not?
Because the reason embedded controllers are set up the way they are is because they are embedded systems which have very limited resources, we on the other hand have vast resources when it comes to UI/Interface
I don't see emc as as something to replace an embedded controler by emulating it, I rather see it replacing embedded controllers by surpassing them, different can be better
But there are things in Axis which could be better, I would just rather put the work in to make axis better :D
yes, but the user interface is not better..
Rugludallur: I think for the hobbyist axis is all nice and so..
but try it with a panel..
anonimasu: I know there are issues, mostly usability and performance as far as I am concerned but I would rather try to improve axis
anonimasu: have you voiced your concernes/issues ?
Rugludallur: did you look at the axis code?
anonimasu: nope, I have not looked at it
well, then you need to take a look..
anonimasu: untill about 2 weeks ago I used tkemc
anonimasu: but I decided to build the new plasma panel for axis since most users will be using that
Rugludallur: well, pyvcp is not axis.. pyvcp is pyvcp..
anonimasu: true, but I would rather develop it as an integral panel in axis than a standalone panel
Rugludallur: well, have a look at the code :)
anonimasu: it's easy to run it in a seperate window for tkemc then
let's continue this when you are done..
anonimasu: will do :)
Rugludallur: also, people with minimills dont mind having the computer next to the mill on the bench..
or using a mouse to do stuff..
though that may be a assumption on my part..
anonimasu: on a happier note the new thc stuff is nearing completion

hmm looking at components scale and mult2, aren't they really just two different implementations of the same thing ?
scale hasa parameter (fixed multiplier), mult2 has 2 pins (I think)
also, scale has an offset, doesn't it?
SWPadnos: in most recent doc scale has gain in
then they are the same ;)
SWPadnos: scale has offset in but in all other regards they are the same
there's a general but slow move toward getting rid of parameters altogether. as that happens, we'll probably see more cases like this
SWPadnos: yup, and there will be an overlap like in this case
SWPadnos: scale with gain as a pin does not make a lot of sense, scale with gain as parameter does make more sense
yep, as long as parameters exist at all
gotta run. brunchtime :)
Rugludallur: why do you say that?
scale with gain as a pin does not make a lot of
alex_joni: My point before was that scale with a parameter is different from mult, scale with a gain pin does the same thing as mult, only difference is the offset which could just be merged into mult imho

EMC2 believes that energetic imbalances impede the flow and expression of Life Force, which we define as your vital energy, your natural healing capacity.
[15:58:33] <cradek> http://www.planetshoup.com/easy/knit/soxemc2.shtml
Energetic Matrix Church of Consciousness (EMC2 )
EMC2 thinks of the energetic matrix as the "true self" of the individual. In other words, we are beings of pure energy. The energetic matrix is the most fundamental expression of our true being. Energetic imbalances exist, not in the body or mind or emotions or other parts of us. They exist in our energetic matrix.
well my energetic matrix is hungry
hmm.. my energetic matrix agrees
my energetic matrix draws it's power from the higgs zero point energy
I just use recycleble ZPMs
I need my pure energy rectified...

Since i now need init values for checkboxes and sliders in pyvcp I'm thinking about implementing a generic init value solution for all input components, any suggestions/comments ?
It seems that <value> is ignored for all of them, Tomp thought that they don't :(
sorry john, this is the root directory
alex_joni/jmkasunich: any thoughts ont hat pyvcp thing ?
It certainly seems reasonable to have initial values
I'd probably stick them in the xml
jmkasunich: I am sticking it in the xml, using the tag "initval" for now
sounds good to me
Rugludallur: that sounds ok
i am having a problem with axis not zeroing when i hit the touch off button? do i not have an option set right?
the numbers stay where they were beforehand
chr0n1c: can you describe the exact steps you are doing?
well, i load axis.. turn on the machine
home all 3 axis'
then proceede to touch off all 3 axis'
but... they don't touch off
they stay at whatever number it is from the turn on pos?
chr0n1c: are you using any offsets?
what emc2 version?
emc2 axis 2.14 i think
what is the gcode to clear offsets?
let me try that
i didn't see it in the g-code reference
unless i missed it

L2 is a work offset with a P augment to define which one
p value out of range with l2
G10 L2 P1 X0 Y0Z 0
G10 L1 would be a tool offset - but is not supported in EMC2
To set the coordinate values for the origin of a coordinate system, program
G10 L2 P - X- Y- Z- A- B- C-, where the P number must evaluate to an integer in the range 1 to 9 (corresponding to G54 to G59.3) and all axis words are optional. The coordinates of the origin of the coordinate system specified by the P number are reset to the coordinate values given (in terms of the absolute coordinate system). Only those coordinates for which an axis word is included on the line will be reset.
Axis runs in G54 so use P1

alex beat me...
didn't mean to
awallin: hi, long time no see
Maybe someday the will add G10 L1 support - but no one has really needed it yet.
alex_joni: hi, yep been busy with work and with the servo electronics on weekends. no time for emc...
awallin: I know how that goes.. unfortunately
now that the elextronics is almost done I'll do some HAL testing + pyVCP next weekend. maybe even get the motors running!
ok, when i close out axisand restart it... it should reset all the offsets?
but it doesn't?
only if i reset the whole computer?
awallin: here is something that might cheer you up: http://imagebin.org/8213
resetting the computer should never be needed
what is going on is... i use a whole bunch of different programs to write the g-code and they all put junk at the top for offsets and stuff...
if something (offset, whatever) is lasting between runs of EMC, it was probably stored to the .var file
chr0n1c: if you set some offset those won
do i justneed to start editing it out?
chr0n1c: if you set some offset those won't be forgotten
no matter what you do
down to straight xyz moves?
they get written into the var file on shutdown
and reloaded the next time
is there a way to clear all machine vars?
awallin: btw me and tomp have done some work on pyvcp, mainly just enabling default values to be set at init
chr0n1c: yeah, replace the var file
with a quick mdi code?
overwrite it with one from /etc/emc2/sample-configs/
awallin: Have not commited anything yet though, want to see ?
if your code calls any other work coordinate sys then you will be lost (g55-g54.3)
ok... will try brb
chr0n1c: make sure your ini doesn't have a POSITION_FILE entry
that one saves the axis position on shutdown, and reloads it
that's usefull on small machines without home switches
Rugludallur: nice screenshot. I'm afraid I don't have much time to review your code even if you would send it. Probably best to just commit it and have the whole emc community review it
awallin: ok, I will commit it tonight probably
awallin: new plasma design is done complete with sim, plan to commit it later tonight to
awallin: might even throw in a video or two of the cutting
i may use that file...
do i need to create the file or jsut add a link to it in the ini
Rugludallur: videos are always nice. I practiced using a DV camera and google-video two weekends ago at the helsinki model expo. There are two clips on my blog www.anderswallin.net
awallin: ill check it out
awallin: nice pics :d
oh btw it's not cnc related if you were hoping for some milling/lathe videos :)
chr0n1c: just add a link in the ini
awallin: you fly, drive or sail models ?
look at some of the sim configs, I think one of them has it
Rugludallur: I've had some cars many years ago but late it's been mostly the sailing boats
awallin: those sailboats are brilliant
there is some awesome cnc vids on youtube
a couple emc machines
i was hoping there would be more emc machine vids there
chr0n1c: there will be in time
i think that did the trick for fixing my offsets
but we're always happy to add more
chr0n1c: so if you have any.. just send 'em over
i will put some vids of my machine up there when i get it tweaked
and i jsut put up a shop light over the bench so i will have good lighting for the vids and pics now
I tried to make a list of EMC videos some time ago: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos
if you have links to more of them, please add them to that page.
awallin: here's a newer one thanks to LH http://www.linuxcnc.org/content/view/35/13/lang,en/
a lot of those vids didn't play because i don't have some crazy codec for them (from the wiki)
question for ya about motors if you can help
got a rather large spindle motor on my lathe
and it only has 2 wires that feed it
would that mean its a DC motor?
N10 G20 G40 G80 G90
N20 G92 X0 Y0 Z0
that's the code that screwed up my offsets?
i need to see what it does still
i don't know off the top of my head
feoc: could be either dc or ac
ok... so if i get g92 out it would be fine?
hmm, funny that a motor that size isn't 3-phase AC
lerneaen_hydra how would it reverse direction ?
I'd try it without it
i was expecting it to be 3 phase
depends on if it's dc or ac
It will also change the part height offset with that G92...
im not sure
how do i find out
how does ac reverse?
you can't reverse the polarity on it can you?
ac would vary, probably there's a capacitor that you can move internally that drives the second phase
if it's dc then just reverse the polarity
it could be made for only going one dir. though if it's dc
it should say on the motor though
i thought you could only reverse an AC motor with 3 phase
46 - 380 volts sounds like ac
the plate doesnt seem to have any info on ac or dc
universal motor maybe?
they may be different windings inside a cover that you can hookup different for diff voltages
"emc2 uses software counting on the paralel port to see how fast the spindle is turning." >>> spelling typo on parallel.
inside the cover... should be a diagram if that is so
if i tryed running some current through it DC would that damage it if it wasnt ?
feoc: no it won't be damaged
I doubt it, unless there's electronics in it I don't see what could kill it other than heat
try with a small DC voltage. smaller servos will turn nicely with only a 9V battery
if it's an ac motor it won't turn at all
well its not small by any means
it looks like a train motor
if it's a DC motor you should see the brushes
theyre usually replacable
try a 12V dc car battery with a fuse at 10A or so
a (v won't turn it if there are belts attached
there are belts attached
*what's wrong with belts
feoc: to test the motor at no load, remove the belts. do you have a picture of the motor ? might help
that was for something else
i do have a pic
but i gotta go get some food
ill get it off my phone later on if i can
belts put a load on a motor.. so you won't get far with a little 9V battery
alex_joni: nice link to the hexapod project. looks like serious cash has been spent on the rails/ballscrews/servos/servodrives etc. is this EMC'er anyone we know ?
Alex or... : whoever handles the Linuxcnc page... - that typo on the threading page... its not that we linux nerds can't spell, its just we can be lazy typists.

Martzis is now known as Martzis
seems as though i have a 3 hour engraving program on my hands
what spindle speed?
ehh, my dremel.. but my motors and slides can only keep up with 10 ipm
i really really wish i had a servo driver and some motors
i am using tiny 5 volt steppers and a stepperworld sp3 driver card
oh, and an atx power supply
unipolar or bi?
i'm new to all this
i am amazed i even got it all working!
i have been drooling over the xylotech driver.. i could give my motors more juice with it maybe?
can that board take 34V?
it has tiny 1/4 wat resistors and stuff on it
there isn't much documentation for this board
and the guy who sells it stopped selling it and said he had no idea if it would even work with emc
and that's all the help he had for me
i mean it's not listed on thier site for sale anymore
there is two voltage inputs on the board...
but i have them y'ed off to the same pwer supply
I saw the sp2... and a fet 3
that's how the wiring diagram they sent
i bought the sp3 about 4 years ago to play with
then it sat in the closet till a few weeks ago
did you hook up 4 wires from the PC supply - Red - blk - blk - Yel ?
no... i am only using the 5 volt side
Yellow to V+ - Red to the 5V blacks to the ground (4 screw posts)
should i hook the 12 volt to the motor?
the paperworks say to use the 5 volts... i didn't wanna kill the card with more volts
cuz i don't wanna buy a new driver right now
you can use the 12V (yel) but you would need to and load resistors.
need to add
but that would give you more speed
voltage makes speed, Amps provide torque
i don't have any resistors handy
i could get away with around 7 or 8 volts maybe?
i can get the speed, the tourque was the prob
plus without good docs it would be hard to calc the proper value
so if i use 12 volts and use resistors to get back to 5 i would have more amps for faster tourque?
would they need to be ceramic resistors or plain old 1/4 watt?
not exactly - but using the higher voltage allows the windings to saturate faster - so the torque does not fall off as quick at the higher speed
steppers have max power while stopped
as they go faster the torque drops off
this is because the "on" time duration for each step gets shorter to the point that the winding does not reach full saturation
i'm following ya here i think...
so i won't get much better with these motors and driver most likely...
i think my boss mentioned he had some old motors from a cnc they stripped out and scrapped
but.. he said they couldn't find them in his barn lol

chronic : is there any stickers on the steppers to spec what amp rating the windings are?
whois burning rope?

i am by no means stupid
i might make stupid decisions sometimes though...
but don't we all
chr0n1c: it's called life
1A - is that the board rating - or off the motor?
ok, seriously stoned and on a munchie run
on the motor tag
them is dinky
i haven't found ny amp rating that i can run through the card to the motors yet
yeah dinky... ;)
my mill is dinky too
yeah, so I've seen
but that is like a lite single stack Nema 23
i am thinking of building a bigger mill and then using the parts from this mill to make a vinyl record cutter
record cutter - as in using old records for artwork?
yes.. when i bought the card and the motors i had no idea of the tourque i would need for these slides
it could be artwork, or actually cutting records
putting the audio in the grooves
i figure i can re-use old vinyl records by sanding the old grooves off
then re-cutting them
I'm thinking that with a good chopper drive, maybe a bigger stepper on Z that little machine could really move..
i would really only need two axis' one to move the head up and down and one to move across
you going to repress - or make a "Recorder"
make a recorder
i got my dj buddy scrounging for old turntables made of sturdy wood to be the cutting platter/base for it all

sweet i can do a rotary with it also
see a chopper stuffs High voltage into the motor windings fast, then cuts off
then hits it again as the power bleeds off
this gives you much higher USABLE speeds
and its self adjusting to the motor to a point
want to try one?
the board... i am considering it
i know this sp3 is a toy
i want a machine... not a toy...
well - there all toys...
i wishi had done more research befor i bought the sp3
My IH is a toy... until it starts to pay for its self
but it was good for learing to this point
the Xylotex would also work with your motors - even give you more torque - you just don't hook up the center winding taps of each motor
use only 4 wires per motor
yeah i was looking at that
how does that effect the positioning and stuff?
only using the 4 wires
i mean does it change the steps?
has noting to do with position
... this g-code is taking like 20 mins to load into axis
unipolar is like a "W"
chr0n1c: how big is the file?
usually axis loads pretty quick
the center wire goes to the midle point
i'm doing an engraving in lexan of a drawing my buddy did... it's 2"x3" and it's 3d... so there is a ton of xyz moves... with a .030 v cutter
"a ton of moves" does that mean the g-code file is 100K, 1M, 10M, 1G?
4,731 kb according to windoze
what was that final N#
probaly less then 500K lines then...
I wonder if cradek is lurking about....
I think they optimized axis to read g-code pretty quickly
on smaller files
for a file like that a couple minutes might be expected, but not 20...
i am using an ancient box to run emc
how much mem?
p2 233... could that have something to do with my motors not being up to par?
333 mb ram
no - you said you were getting the speed - but losing spets if I recall
that's a bit lowend for axis
ok.. so it is just the motors/power supply/driver
losing steps is drive/hardware not PC
mainly power supply and driver
though that CPU would limit the max pulse stream you could gen - but the drive/pwr is your current problem.
JMK - did you see that short vid I posted yesterday?

this is the same base machine

hmm - let me check
Skullworks_PGAB: nice message
had guys at work try to go snooping
the M of mill needs to be uppercase

[21:24:10] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo
is it cutting the end off on your clients?
you said it in lowercase earlier
and now with a space
[21:26:21] <alex_joni> http://www.skullworks.net/include/X3_Servo_Mill.mov
file is X3_Servo_Mill.mov
have an ftp window open
the link I pasted works
well.. it downloads at least
no codec here :/
eh, so i bought the hobby cnc driver kit
looks like i'll be inhaling lead smoke soon
thats the unit I'm trying to convert
doh! more drain bramage!
chr0n1c: not if you're saturated with weed
lead is the least of my worries
i just made myself a .090 thou ball nose engraving bit
out of the back half of a drill bit
it should work..
Alex your on a Linux box now..?
Have you tried VLC media player?
my lathes drill head drive lost its magic smoke :(
has all codecs built in
be aware - the farther away from the original cutting edge the metal gets softer
yes... i an engravng lexan
should be fine
thanks for mentioning that though
hoping its just transit damage to a supressor cap
would be good to know if i wasn't a machinist ;)
dishsoap and water 50:50
coz its got a crack right down it
i have real tools at work lol...
hopefully replace the cap and it work :(
i am building my home shop out of junk
lexan cutting fuild and easy cleanup
i been using wd40
it's all i had around
i do have dishsoap thoughj
never thought of that
works too - but more mess
maybe dilute it more since your engraving
yeah... would some tranny fluid work? i have some of that in the grage lol
of course it would work.. but i'd be covered in red oil!
some stuff will attach that lexan
like carb cleaner or break cleaner
i always used tap-magic for engraving when i had a real milltronics mill :(
that stuff is da bomb!
any one here ever made a gantry mill?
* Skullworks_PGAB almost wishes he could find a Partner 1 in a junk pile somewhere
kerosene works GREAT for AL or Brass
feel like building somthing stupidly large when iv gotten used to it on my hurco
i am trying to talk my buddy into building a 4'x8' gantry mill
he is awesome with wood
and i'll do the electronics
I have just installed the joypad_hal. It works. When I push (and hold) the button to turn the flood coolant on the coolant turns on/off/on/off rapidly for as long as I hold the button down. When I push and release the button the coolant doesn't change state reliably. How would I incorporate a latch into the code to make the state change one and only one time per each button push. I have tried to figure this out. It seems as if I am close BUT
Feoc - did you get the Hurco up?
not got it pid tuned yet
fucked about with some random figures enough and got it moving now
great - its progress
are you using the hurco drives and such or did you gut it?
ill sit down and pid tune it when iv wired in the computer properly coz im having to remote X in via my lappy and its too sluggish
i am using the hurco drives and motors
it came with a burny servomate drive
stustev: maybe add a debounce to the button?
there is a component called debounce..
quite good to watch the mill move around doing the spiral and 3d chips demo codes
s w e e t.
I haven't tried that. I will. I added two and2's and two not to the example in the wiki. All above the two and2's and one not in the example. The debounce is used to delay the signals?
chr0n1c: don't always assume native speakers
i was about to explain
i keep forgetting we are on the internet
stustev: the debounce component is meant to filter out unwanted toggles in a signal
and it's the whole world
for example noise which can be incorporated into an digital signal
Would the debounce be added between the push button and the signal? BTW I am from Wichita, Kansas. This is almost a foreign country for some people.
stustev: you should have it like this:
button<->signal<->debounce<->signal<->halui (or wherever it's connected)
Thanks. I will try it.
Skullworks_PGAB: finally got around to looking at the vid... fast machine
(for its size anyway)
yeah - well I don't expect to get that kind of speed - he can run it at 400IPM
those are Nema 23 410oz-in from Camtronics
thought so, but I already closed the window... too lazy to look again
410 is a lot for a servo
is that the peak rating?
I think so
"MCG ID23-005 PMDC sevo motors 400 oz in peak NEMA23 Frame PMDC servo motor with encoder"
he went cheap on the screws - is likely going to replace the screws because the "transport" grade has almost .005 slop
good night all
where would be a good place to put a wiki page on tuning emc2 to use a rotary table / A axis?
the emc wiki :D
[23:13:29] <Rugludallur> http://wiki.linuxcnc.org
you can upload files to
anyone playing with apt360 want to try a front end for it?
* asdfqwega smacks Rugludallur with a frozen waffle
I know about the emc wiki...just where to insert the page?
what url ?
or how to insert it ?
where would it be appropriate to attach it?
[23:18:32] <Rugludallur> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TuningRotaryTables
and then link to it from pages on tuning is what I would do
I was over-thinking it :)
