you can also try ctrl-alt-<keypad minus>
or ctrl-alt-<keypad +>
that switches between the available resolutions

skunkworks: good for you
'you send me the amps, I'll buy you your choice of geckos'
I got the impression (just skimmed the thread) that they are brushless
send amps _and_ motors
I'm getting _really_ tired of building a tower to mount my vise on every time I want to mill something
still need to set up the clamps and such
just get a knee mill and park outside?
hey - that's my technique
I have a knee mill in the garage, but it isn't CNC
and the garage is almost always either too hot or too cold
don't forget the rust factor
yeah, that too
* jmkasunich whines
building a tower?
the table is well below the reach of any reasonable tool on a ShopTask
so you have to put the vise on blocks
you need about a 5" lift kit :)
well that's a hoser.
there are cheapy riser blocks on ebay for that
hmc's make heavy use of them
the trouble is that the table is the toolholder when you have it in lathe mode, so you have to get rid of the lifter whenever you use it as a lathe
so it's the on-again/off-again thing that sucks
you wind up with setups like the one here: http://jmkasunich.com/cgi-bin/blosxom/shoptask/spindle-encoder-bracket-01-07-08.html
i'm telling you man, there are lightweight (for what they are) risers to do exactly that
often like 8x4x4" ribbed out in the middle
and one of these days I'll get one
the more I use the Tormach/KTool face mill, the more I like it
oh - you got one of those?
it sure seemed to chew through aluminum
it chews steel nicely too
are the inserts readily available?
for some valiue of readily
each pair of inserts has 8 edges, I hope I don't need inserts anytime soon
its made by a US company that sells to real machine shops, the inserts must be available

Thanks for the links and help, I have alot to learn, man compile a kernal for a touch screen, crazy, oh well.
KTool lists it for $177, Tormach sells it for a bit over $200, with the TTS adapter ring in stalled
antichip, it has nothing to do with the kernel
you are prolly right and I am just a little overwhelmed
heh - easy enough for that to happen
the touchscreen is actually two devices: an LCD display and a touch input device
the touch part has nothing to do with the display part - the resolution problem you have is a monitor problem only. fix that, then work on the touch input part
(the touch driver needs to know the resolution of the screen somehow, since it translates analog values into coordinates)
so if you change the resolution later, the touch driver will need to be re-setup
hm, on my hardy machine, I can't read the font in classicladder
on dapper it seems ok, if a little smaller than most other stuff
is it a "non-standard" DPI monitor ?
I've tried it on 2 x-servers and they are both set to 75
[02:00:23] <cradek> http://timeguy.com/cradek-files/emc/font.png
FontDesc = pango_font_description_from_string( "Courier New 8" );
not very configurable...
I wonder why hardy renders that so badly - it should be ok
(at least as ok as dapper)
do you have an extra font pack installed on Dapper?
It is 800x600 I am sure
SWPadnos: courier-new is a standard installed fontI think
antichip, look at the file /etc/X11/xorg.conf
hmmm - nevermind, the needed information isn't there, so I can't have you modify it (and I'm not exactly sure what needs to be added)
cradek, well, lemme see if it looks sucky on my machine - hold on
I wonder if the A64 RT hardy kernel will work on my laptop
it lists the vid card as generic and has 1224X768 800x600 and 640x4806, I removed all of the 1024x768, but I don't have permision,
when you want to edit, go to a terminal and type `gksudo gedit`, then load the file
you'll be asked fora password - the one to use is your own
if it actually has resolutions listed, then comment out (by putting a # at the start of the line) all the ones except for 800x600
crotchetyGu1 is now known as crotchetyGuy
the answer is no, the A64 RT hardy kernel doesn't work on my laptop
so I can't tell if the CL font is readable :)
looks good thanks for the help
any sugestions on a parallel isolator breakout?
nope. I haven't used any of them myself, and every one I look at has something I don't like about it
so I think about designing and selling my own ;)
so you don't use any isolation between parallel and ?
I haven't converted my mill yet :)
I also don't intend to use the parallel port, except maybe if I need extra I/O
I have Mesa and Pico Systems cards
I'm doing my lathe now, and wanna play with my optical interupt but don't want non isolated conections.
yeah, isolation is a good idea
I have almost convinced myself to get the parallel mesa
jmkasunich: how do you safely estop a vfd?
if you have a PCI slot, I'd really suggest using the PCI version
no pci in this computer
oh - right
it says to remove power in run mode 'only in an emergency' and doing it 'too much' will 'shorten the life of the device'
how's that for fuzzy
cradek, it should have a safety stop input or similar
you don't have to power off the contactor, you should be able to run the estop chain or an aux contact to the VFD
cradek: you'll have to read the fine pring
it has an 'external fault' input
if you want to make sure it can't start unexpectedly, the best way is to remove input power
I am definitely switching power to it
if you do that while running, it will definitely stop, but as SWP says, it isn't the kindest thing to do
that way I can sequence it on, too
it stays alive for many seconds after power is off - big caps I guess - I could assert the external fault AND remove power (it says external fault causes a coast to stop, so it won't be trying to brake or regenerate)
is there a brake on the spindle?
oh, hmmm. that's a bummer
the external fault is probably a pretty good way to go
I was about to say that stopping is faster when it isn't coasting, but if it just coasts on estop then who knows
one nice thing about VFDs (compared to DC servo drives) is that a "stuck on" IGBT or other power switch won't make the motor run away
I will external fault + remove power, so it's coasting
is there a place to put a DB resistor?
SWPadnos: DB resistors can make a controlled stop faster, but won't help with a coast stop
I was jus about to ask that
coast stop is more reliable, controlled stop is faster, pick your poison
you could do something interesting with NO/NC contacts - switch in a big resistor (across a couple of legs) when it's e-stopped
IMO, normal stop (M5, esc, etc) should be controlled, with DB, but estop should be coast + remove input power
that would give you a crude brake
I think they avoid talking directly about safety concerns in the manual
that's the safest thing to do ;)
SWPadnos: if this is a normal induction motor, the crude brake would be very very crude
the residual flux in the motor will dissipate in a small fraction of a second, then shorting the windings will have no braking effect
it'd be different if it was a permanenet magnet motor
well I have a spindle - it's just about an actual lathe again
you're making really fast progress
it's kinda sad when it takes me over an hour to draw and program a part, and 2 minutes to cut it
but its cool too ;-)
and it fits!
the plug for the big slot in the spindle fits like a finger in a glove
I should get my 5mm drill rod from McMaster tomorrow to pin it in place, then I'll be ready to bore
I just finished my exam "programming in C" 40 minutes ago. it was great, 'cos it started out with "Create an empty C++ project..."
hehe nothing too hard then
basically the entire exam; first question was just a for() loop, and the second was just creating a function and multiplying 2 floats passed as an argument
thats about it
c++ for 2 year olds?
it was /SUPPOSED/ to be C
it was an exam that i skipped in the first semester that i still had to take.. intro to programming
accoustics tomorrow, and physics, then optics, then "communications", and french, then digital systems, then electronics and programming (again), then chemistry, adn physics again, plus computer systems
thats my exam schedule
