I need another project for christmas
ive been wiring my project today
with Big Volts?
yea , 180 vdc servo amps
how man amps are these beasts?
low amps , peak is 10 amp each motor
well the motor are only rated to 120v
so .. 2.2hp max
big enough though
1/3 hp each motor]
* robin_sz tries that again ...
120V * 10A
1200/746 = ?
i have it running through a 1500 kva toroidal trnasformer to the servo power supply
ive got more than enough power :-)
probably more than 1/3hp though ...
you can get more than that out of a nema 34 stepper
ive got it all going into a 30X36 enclosure ,if you have ever seen the inside of a Haas controller it is pretty much laid out the same way
the only Haas stuff ive seen is the PSU on my laser
and thats very neat
the computer , the amps , transformer ,I/O boards , vfd and the computer all fit insdide but it is tight
this is for your mill right?
* robin_sz forgets whose building what these days
i will be running a lathe and a mill from this controller (not at the same time) :-)
running emc for the lathe?
the lathe is a grizzlt 12X36 and I replaced the single phase motor with a 3 phase so i can have constant feed rates
vfds are handy
no i am not runing EMC at the moment , I am using a Galil motion card and Camsoft CNC
mach2 has some good stuff for lathe work
the threading stuff is quite qorkable now from what I understand
I would have liked to use MAch2 but I cant get over the fact that it still isnt a truley closed loop system
yea I know
90% of emc installs arent either
I'd say most people end up using stppers, only about 10% use servos, from my random guess anyway
I worked with a open loop stepepr mill at work , a old Bridgeport Series 2 , and we lost a bunch of parts
over the year due to loosing steps
mainly in the Z axis, right?
nah this machine has problems its all over
the old bridgeports had a weakness in Z ... if the lube ran a bit low, it just stuck
probably wouldnt have been a big deal with part loss but we are machining castings
bar stock no big deal just cut another
servos are much better in almost all respects
but, homebuilders usually do them stepper thing.
back in 10, teatime
well I got great deals on everything I have ,mainly all Ebay , probalby saved 50%
damn ... I think I have the urge to buy a CNC lathe ...
dont you just hate it when that happens?
if you did, maybe you would put threading in emc
I;d buy a working cnc lathe with a controller
* robin_sz looks at a nice tasty Mazak ...
* paul_c is away: making chips
* paul_c is back
got the mount points in BDI-4 fixed...
Good. Matt said that he had a problem installing on his older computers.
How old ?
What directory structure are you using for supermount?
These were the boxes that they are shipping now.
Not enabled supermount just yet...
and what problems is Matt having ?
Remember that box with the lcd on the side. That's the one.
ye gads... Vintage hardware !
Thought you like that.
* paul_c runs through an install with BDI-4.03 (on a 433MHz board)
been neglecting irc
which is nothing new =)
asked a few non biased linux dev's about 2.6
got some interesting feedback
There's a large amount of discussion on this right now.
It's my take currently that the 2.4 kernel series is antiquated and a
patch disaster. In order to get normal features that you would expect in a
2004 OS, and an advanced compile system, you must either patch the shit
out of 2.4 (and probably make it unstable) or you can go with 2.6.
Right now, no kernel devs want to maintain a stable kernel because "it's
boring." So they are saying that the distributions should be responsible
for a stable kernel. I think this is the worst idea ever. I believe that
they will realize this in another month and force a kernel dev to maintain
the stable branch.
What's happening right now is that 2.6 is being maintained more like an
unstable kernel branch, but that doesn't mean that it's not stable. Since
2.6.7, the VM has been worked on extensibly. I personally, have had a
couple stability issues with 2.6.7. They are extremely rare: I'm running
it on 12 machines, 2 crash once a month, the rest run perfectly.
I believe the 2.6.10 kernel to be in excellent condition. The only reason
I'm not using it is because the grsecurity patch is not available for that
version. But you don't need that, right?
Basically, I highly recommend the 2.6 kernel, and encourage you to use it.
Are the realtime patches available for it?
im going to get booted for that haha
[21:07:59] <tbl> http://obstinate.org/t/linux.txt
for those who don't like the sizing
also the 2.6 FS is really really cool
its about time that a x86 mainstream unix has REAL journaling
Thanks for that update on kernels.
I ran SuSE a bit here with 2.6.7 and it crashed twice.
my fedora core 2 server only crashed because the breakers went live
bleh @ those bloated OS's though
the only linux's that i would run "off the iso" would be like debian or slackware
i would just assume do a linux from scratch
gentoo is pretty cool too
(basilcly an automated LFS)
what boggles my mind
is gentoo has no automated installer
to keep the "un-skilled" people out
tbl: you have to admit that it works ;D
now, i am not exactly unskilled when it comes to linux / unix os's but i don't think i should have to read 50 pages of docs to get an os installed
i will never install gentoo
i have shells on boxes with it, and it seems neat
I installed it once and it was tedious. I think it's for linux wankers with neon computers. I don't see any problem with binary packages and they are faster when I have to get on to doing actual work.
