theorb is now known as theorbtwo
no, sounds cool though
is support for the 3x20 mesa cards the same as all the others? or are there different levels of support 'maturity'?
The driver and firmware are all the same for all PCI/PCIE cards
(firmware source is the same, bit files are different of course)
cool, so then one should be able to upgrade between cards without much fuss
IIRC - seb and matt tried one of the pcie cards on smithys lathe. Seemed to be pretty transparent.
(I don't know what smithy uses normally - 5i20 or the parallel port one

you can use stepgen to make your steper 'behave' like the dc drive via different hal directives
skunkworks: Thats neat! is that a shaft with a keyway or splined shaft that drives the shorter axis?
pcw_home: it is a ball spline
3 races around the diameter of the shaft. (so far we see only .0002" backlash in the whole system
.0002" ?! take it back and gt a refund!
did you get Y going?
you see his video?
[01:51:03] <Jymmm> http://www.youtube.com/watch?v=QU_O_Z7Vv8c
Nice that the Servo motors dont need to move
yes but I don't think he has Y moving in that one yet
no Y yet
skunkworks: more preload!
I though the spindle axis was Z (shows how much I know)
spindle moving floor-to-ceiling is Y
Z is the tool direction (table moving toward and away from spindle)
silly sideways mill
I'll have to look at a picture of the whole mill again...
it's not that silly ;)
morning from Raini and cold Germany
good morning from cold Poland
but still sunny there
it's warm and sunny here
expecting 29C today
here is only sunny :)
semi-final resting place http://i47.photobucket.com/albums/f163/johnplctech/Bridgeport%20308%20VMC/BP308-20.jpg
was the bike supposed to be used to push it in :)
jthornton: cool, congrats
jthornton: If that doens't work for you, I'm happy to store the bike at my place if you need the added room
pcw_home: you can see the ball spline here. (the one closest to you) 2 of the 3 races are visable. http://www.electronicsam.com/images/KandT/conversion/xaxis/ballscrew.JPG
the normal lookin spline is for the B axis. It doesn't have to be as accurite because the table positions in 5 deg increments.
skunkworks: that ballscrew could tear my house apart!
It's a toothpick
tent == house >_<
* skunkworks has really really small hands... ;)
skunkworks: tell me about it! ;)

heh. cute lil buggers aint they =)
* elmo40 notices the tumble weeds... everyone must be little busy bees at the moment.
elmo40: Quit making so much damn noise, I'm trying to sleep here!

I'll sleep when I'm dead
Leonardo Di Vinci
he was quoted in saying that. I whole heartedly agree with him. (and you ) ;)
Too bad I can't live up to it though =)
I think I have a bad stick of RAM. the computer for the mill keeps locking up on me. rather annoying.
Toss in a LiveCd and run memtest for 24 hours.
don't need it that long. they usually pop up in the first 3min.
good excuse to upgrade everything :) hardware and software. I want to give 10.04 a shot.
I have so many spare parts lying around that I can not justify purchasing something new. It was the thought that counts LOL
P3-1GHz is too slow :( maybe the P4-2.8GHz mobo works.
elmo40: too slow for what?
for gnome in 10.04 + axis + other things.
besides, I only have 256Mb of that RAM.
I'd say 512MB minimum
I built a little machine for under $300.00.. Dual Core Atom with 4gigs, 3 parallel ports in mini-itx form factor.. Oh. 32 GB SSD in it, boots up in around 12 seconds (BIOS post and everything)
3 par ports? are they through the pci slot?
One on board parallel board (using a header), then I got a dual port PCI card
what does the pci one communicate with? is there a difference in latency?
Umm. I would imagine it's the same as onboard, infact, I would think the onboard uses PCI too, just not able to remove it..
speaking of onboard. just noticed my P4 mobo doesn't have the rear connection. only pins on the board :/
yea, You'll have to find a header cable.
I bought the PCI printer port card jut to get one.
well, I get to the CPU listing at boot, then a mem-check(which says it is all good) but after that it hangs for 15seconds and shuts off. I know there are thermal protectors for the cpu to kill the system but my heat sink is securely attached with the thermal goop.
I have 2 Socket 478 mobos to try out. one with ddr2 and one with ddr1. hopefully one of them work!
2 P4 cpu's as well. 2.8 and 3.0GHz
ok. none of them worked >_<
but, I have an Asus A7VBX LA with an AMD Sempron 2.2GHz and 1Gb DDR RAM. :)
so far it seems stable
time to check the RAM for problems.
should I swap in the nVidia GeForce MX440 w/128Mb RAM, or keep the onboard video?
onboard video seems to cause high latency fwiw.
Jymmm: you have a laser?
and you were thinking about Laser Cladding?
how much are these machines? http://www.youtube.com/watch?v=PchrxGRZuto
but this is what I would like. robotic arm with the laser head on it! http://www.youtube.com/watch?v=v0EtLWjVEV4
elmo40: Yes. This is what I have... http://www.engraversnetwork.com/uls/m300.html
really niec video. very descriptive. but a million dollars to get it up and running? robot, laser, powdered metal, power supplies... I bet it is close to a million
I guess it is technically called Deposition? http://www.youtube.com/watch?v=nzNv6Ds2KPY
materials deposition is the general category, it's a pretty broad term
* Jymmm preforms materials deposition every morning
the brute force method to laser cladding
[16:10:37] <L84Supper> http://www.youtube.com/watch?v=fApotOGOMHY&feature=related
looks like even the brute forced method is patented
now fast forward to 0:50 to see full depth of cut! http://www.youtube.com/watch?v=LLC25KbCTxs
I love it. No one at my place has the balls to even try it.
tom3p, Good morning .. I heard rumors that you had written a stripchart widget
DAMN! LawrenceG pounced tom3p for the kill in less than 5 minutes! LOL
Jymmm, lurking in the weeds for days finally pays off!
LawrenceG: Why have you been lurking btw?
Jymmm, rats.... doing a nackup and I forgot to clear trash.... those iso's are a pain in the ...
LawrenceG: PITA == Pain In The Ass
how is the laser project coming along?
LawrenceG: Good. Working in the air scrubber design; think I finally got it down, working out the details now.
ries_ is now known as ries
LawrenceG, ? stripchart? i wrote an svg panel with a bendable velocity curve ( like an s-curve velocity envelope ) for pyvcp_widgets.py
(damn inet is broken everyt few minutes here, sorry )
but i wrote a lot of custom pyvcp widgets ;)
hah last few lines are in the archive so they must have made it thru
the AMD system works :) doing a memtest right now. 1Gb RAM with 2.2GHz CPU.
damn >_< one of the 512 sticks is bad. have to sub it with a 256. So sad :(
tom3p, cool... I was looking for a wx wdget... part way through writing one, but someone said you had done one. The wx widgets are not much different from the pyvcp widgets
florian wonders if AB is strong enuf? use this for a 'cheap' conversion? ! http://www.dmgecoline.com/de-DE/30-dmu-50-eco

what the hell is she there for?
way to make your website look professional
cradek: I think shes the instant chat "chic"
cradek: Kinda like this... http://i37.tinypic.com/nvqukn.jpg
Jymm she keeps poking her finger in her mouth, i find it distracting
DMG make Amazing machines!
I wish I had one of them.
and a machine?
one of what other then the machine? <confused>I am</confused>
is 12 m/min rapid traverse fast?
I don't know metric :P
look at the naked/no sheet metal machine http://www.dmgecoline.com/de-DE/32-highlights
elmo40: at the shell, run units
You have: 12 m/min
You want: inches/min
schwenkrundtich, aka AB
approx 4700 inches/min
google is supposed to be able to do that
elmo40: well you got the wrong answer...
one too many decimal places :P
12 meters = 472.440945 inches
the 55 model has pallet changer (and more vogue-ing latex girl )
[18:21:53] <tom3p> http://www.dmgecoline.com/de-DE/42-dmc-55-h-eco
tom3p: See, she wants your body!
ah, you cant turn it off but you can zoom in till she doesnt 'appear' anymore
i always found on screen 'nerf steel' simulations useless, by the time i could see the detail, i couldnt see where the detail was
that has to win the most annoying award
tom3p: Just install ABP
I don't see anything
tom3p: Then mouse over the girl and you'll see a "BLOCK" link that you click on and your done.
I like the smaller 32 then the 42. no need for a pallet changer in my shop, not mass producing a millions parts/year.
ahh! ADB installed and dmg girl is vermisht
tom3p: Yeah, it's the only FF plugin I use
now then... if I upgrade linuxcnc from 8.04 to 10.04, can I just use cradek's packages to keep everything working ?
tom3p: You can pretty much block anything you like. I block most of the tracking websites and all of google analytics JS crap - just slows things down imo
Jymm, cool, got a list?
wow that eco50 was 100k$
tom3p: Not really, just when I hit a site with annoying crap, I hit ABP, and it pops up a list of things you cna block. I just wildcard them.
ok, on demand, thx
tom3p: Example goto http://cnn.com/
then click on the ABP stop sign and a list of things will popup. notice all the ones that say http://ads.*
tom3p: BUT, is something doesn't work, disable ABP and reload the page, maybe you blocked too much, it happens maybe once a a year or so, or they change things and you have to unblock certain thigns
tom3p: Did you restart FF ?
tom3p: in here please, no need to pm
tom3p: Well, check the plugin, you should have the stopsign all the time in the top-right corner
might be an option
oh THAT stop sign on the menu bar ( doh!)
tom3p: how many stop signs do you see silly =)
tom3p: There's CLICK and RIGHT-CLICK too
yeh, just not noticed in the corner of the screen
ah, Ulf has good point, the Heid CNC uses digital amps ( not pwm, not analog Velocity commands )
has anyone replaced the default Gnome with anything lighter?
LawrenceG, maybe of use http://jstripchart.sourceforge.net/
or ( because Biggles was cool ) http://biggles.sourceforge.net/
sure looks better when arcs don't turn into straight lines...
can you put the gcode somewhere too?
Can I say "g0 z-1 x1 y2 g4 p0" instead of two lines: "g0 z-1 x1 y2" and "g4 p0"? Just to save space and to be more idiomatic?
I think that's accepted, but possibly contrary to your expectation, a dwell takes place before a motion (regardless of the order of the words on the line)
who is managing the experimental SMP kernel? http://linuxcnc.org/experimental/smp/
elmo40: you are free to use my custom build: http://ca.rstenpresser.de/~cpresser/tmp/emc2.5pre_lenny/
I use it on a SMP machine
the lucid rt kernel is smp
the one on the linuxcnc cd
the new one? nice. just dl'd it. will try an install tmrw
Anyone here have experience with the Geckodrive products?
Endeavour: the stepper drives are good.
Endeavour: yeah, some
Which would you recommend?
depends what you need
I'm using NEMA 17 stepper motors
I was looking at the G251, but, they have a lot of different drives.
Not sure what the differences are.
(Reading the specs, but real world experiences would be nice)
I have a lot of G340 for DC motors
and some G201 iirc
they work great
oh, sweet, there's a wiki on your site about rastering with a laser!
I was pretty much in tears trying to implement that last year ;)
ended up paying to replace the old driver board
I have just had a query via my Youtube pages asking for advice on DC servo drives that are Mach3 compatible. Am I right in thinking that Mach only works with step/dir drives? (Naturally I will point him at the LiveCD for EMC2)
andypugh: there are some other alternatives (galil card) for mach, but I wouldn't go there
it's not really closed loop, but a hack
So my assertion that EMC2 is a better bet for servo use is correct?
(I am prepared to believe that for some people Mach is more suitable than EMC2. (Morons, idiots, the deranged, for example :-)
andypugh: not necessarely
yes, emc2 (and even emc1) is a better fit for servos
there are lots of people (not morons, etc) who still think Mach is more suitable for them
people who don't want to try out ubuntu/emc2..
you know what they say about arguing on the internet?
for arguing on youtube comments it seems even more true
Those were only examples :-). In honesty I can see that anyone uncomfortable with anything except Windows would be better served by Mach
yes possibly - depends on what they're trying to do
andypugh: to each his own
It was a PM query, rather than a comment
everybody just knows that linux is hard
and it wont work with their windows software
(the fact gcode is a text file is something they havent found out yet)
I think most make the choice before realising that they are going to want a dedicated PC for the CNC machine.
just wait for Step-nc to kick in
Step-NC looks practically impossible to hand-code. And has been 10 year+ in the making...
alex_joni: i am thinking about adding in the linear motion in genserkins??
Sounds useful. And hard :-)
do i just change the GO_QUANTITY_LENGTH == link->quantity
andypugh: not really hard, it's all there already
i.e. change link->quantity to GO_QUANTITY_LENGTH
moopy: you just need a way to specify it at load time and from HAL
Oh. I had a look at the source and gave up baffled by matrices.
but now I'm off to bed.. 2:38am here
the matrix stuff is very hard
but as said i think its all there already
moopy: yes, it is
so i should be able to do it in 10 mins
so i just change link->quantity to GO_QUANTITY_LENGTH if the joint is linear
I suspect if it was a 10 min job it wouldn't have been left undone?
well if its not a 10mins job its beyond me
No harm in investing the 10 mins to find out, though.
working out all that matrix algebra would take me at least a month
it could take me forever
andypugh: well.. I had no use for it when I put the rest there, so I did leave it out
I suspect you don't need to work it out, just undrstand when to apply a rotation matrix, and when a translation one.
it might be a 10 minute job
andypugh: for this you don't
you just mark each joint as rot/linear
the rest for the calculations is already there
well all i am going to do is add the stuff to read jointtype from the hal config
In that case, what are you waiting for Moopy? Get to work, stop slacking ;-)
yeah, i may do it tonight
* alex_joni is off to bed
Actually, that sounds like an excellent plan.
Endeavour: I have used the G203Vs and some of the older 7A stepper drives. The 251's are derived from the older designs. All of the stepper drives are good IMO.. I have never used the Gecko servo drives..
I picked up 3 G251s today.
I think you will be happy with them ....
Their are cheaper drives ... but to me the Geckos are pretty much at the low price end of anything quality...
I'm trying to make a no-compromises machine here. Not for milling or turning.
But everyone here really hated the stuff from Allegro Micro and I got pointed to Gecko many times.
As long as you don't exceed the current/voltage ratings of the Gecko drives .. I don't think you can go wrong with them... I have used some of them in some hellish applications where I expected them to fail after a year or so .... not the case .. they are hard to kill..
