Hi all, Can anyone assist in reprogramming a Mesa 5i20 card that will not reprogram SC5I20L IOPR12.BIT REGMAP ?
sounds like you want PCW (a guy on here)
but he isn't on atm
anyone used Vectric stuff? (Cut-2d, v-carve pro,etc)? What post-processor?
ries_ is now known as ries
howard: you would not invoke sc5i20L with regmap as an argument, but a card number
(this is really not EMC related since EMC driver for our cards , hostmot2_pci loads the firmware itself)
I moved the card to another slot and it has programmed ok. I didn't use regmal as an argument only IOPR12.BIT. Thanks for the reply :-) cheers from down under Aussie. Bye for now.
this takes forever! and to be cost effective I bet you would need 30 machines. http://www.youtube.com/watch?v=Vs8RMnknO2E
atmega, I have used vcarve... I believe there is an emc2 post ... not sure where it came from, but its called EMC2 Arc Inch(*.ngc) in the post processor menu
atmega, see http://filebin.ca/vtfmus/EMC2_arc_inch.pp

any of you guys ever milled soap?
Valen: sound s liek a fun project for a birthday gift :D
friend is doing it as a gift for a product he is selling
Valen: sounds like possible with a vbit...
I was thinking so
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-10-05.txt
yay @ skunkworks
Thanks alex. getting there.
(pay no attention to the cubby guy next to the machine)
took me a bit to figure out what the h was for.
Hmmmm, YT is having streaming issues at 24s and 40s
Jymmm: looks ok here, might be on your end
now I could get the tool changer arm working
alex_joni: Might be streaming movie weirdness. NetFlix's streaming provider (sky.com) is filling up the fw logs =)
took a bit to get the scaling right - we ended up taking an access pannel off and counting the gears finally. made no sense. It was like 52 and 23 teeth
relatively prime on purpose I bet
cradek: Damn geek
cradek: Only you would see those are primes =)
heh 52 is not quite prime, being even
cradek: It's early, so I'll take that as not awake yet geekness =)
skunkworks: what's left on it?
lots ;) gear shifting, tool change arm, B axis, pallet changing.
most of that is just programming though. (other than mounting an encoder on the spindle motor)
then some BIG chips
oh - and figuring out how much torque we need to rotate the b axis and mounting a servo.
but that should be pretty easy.
I don't think it will take much torque.
it rotates on a big thrust bearing
we have to bring up the last hydraulic pump also (the 1200 psi one) it does the table clamp/lift and cullet clamp unclamp.
skunkworks: cool, so it'll be done this year ;)

Why NOT PuppyLinux..its 130MB base Linux,... http://www.puppylinux.org/
downsized ubuntu still got 600mb
Puppylinux is on USB boot
but the top is too clean
alexis_4315: feel free to use puppy with emc2 if you want
emc2 can be compiled on quite any linux
i cant insatll rta+emc2, any body tell me howto? on puppy?
yes the problem is always actually doing it :-/
[13:48:58] <skunkworks> http://electronicsam.com/images/KandT/conversion/yaxis/Ygears.jpg
rtai+emc2 quiet tricky
there may be something on our wiki.
getting a bigger usb stick and using ubuntu would save you many days of work
wiki of installing stepbystep ?
you can see the split pinion gear
as cradek said, it's at least a couple days if not a week or two of work
I like your idea of putting the printer over the monitor (and shading the monitor)
Thanks !! =alex_joni
(that picture should have been rotated...)
[13:55:38] <skunkworks> http://electronicsam.com/images/KandT/conversion/yaxis/Ygears.jpg
i cant find ftp://ibiblio.org/pub/linux/distributions/puppylinux/usr_devx.sfs for installing procedure
alexis_4315: don't expect any puppy help in here :/
squashfs2.2-r2.tar.gz , adeos-linux-2.4.31-i386-r18c1.patch
I notice that wiki entry is from 12 Dec. 2005
last changed in 10 Jan 2006 (only the top note was added)
these are notes someone made when they got it to work years ago - you will not be able to use them as step by step instructions without understanding them
right, but you can probably inspire yourself from what has been described there, and apply it to more recent puppy releases
unless puppy linux changed architecture, packets, and whatnot (which I think is quite possible in almost 5 years)
5 years !! ..we need a EMC2_auto_installation program thats has log
we need pony linux
i count on you
i search every where, didnt find ponyLinux material
[14:12:07] <alex_joni> http://www.wikinoticia.com/cat/tecnologia/softlliure/66933-pink-pony-joc-de-carreres-multiplayer
ok i find this for me http://wiki.linuxcnc.org/emcinfo.pl?Installing_EMC2
its all on emc2-install.sh
elmo421 is now known as elmo40
(i use to work with live-cd)
does the OS contribute to latency?
elmo40: the OS is what runs when RTAI isn't
so it's the primary cause of latency ;)
if you had an ideal system (where you only had RTAI running) then you would have ideal latency
usually the major causes for latency are interrupts (drivers - especially graphics, network, usb, etc)
now the idea is to minimize all interrupts. a motherboard with no serial devices? built in vid or PCIe? (or agp?) no nic? sata or ide? basically, a board with a par port, flash drive, cpu, ram, north/south bridge, video...and nothing else?
<elmo40> ...all u need is AT32UC3A3 chip $15 USD
programmer is not include
AT32UC3A3512 or AT32UC3A3256
disk implies interrupts (unless you rewrite the IDE/SATA driver for polling), video implies interrupts, especially if you expect graphics, any peripheral that accesses RAM implies DMA, which will block CPU execution (likely the major cause of latency in a PC) ...
g-code in, movement out
and after all the optimization in the world, an AVR at 20 MHz still has 10x better latency
we cant denied interrupt on PC... 1chip of processor must do bios,vga,sata hdd,usb,lpt etc
AT32UC3A3512 has 66MHz speed
can do sdcard,mmc,sdram (MB), all
$4 dolar if u buy it from atmel ;))
AT32UC3A0 256 much cheaper $9 dolars
z also ....prety much alike to 3A3 series
alexis_4315: and 2-3 years of coding and bugfixing
be my guest
some one telling me this, and tryng to developt it... thats why i try puppy for tommorow, live-cd for now
2-3 years... but maybe elmo40 would like to start for it from now
i dont denied thats LiveCD is the must fun ways
<SWPadnos> AVR at 20 MHz still has 10x better latency.... --> u mean PC vs AVR1 20MHz
AVR2 has 66MHz
I mean that an AVR (8-bit) at 20 MHz has a latency of 4-7 cycles, which is (a) very fast (0.2 - 0.35 uS), and (b) very deterministic (only 3 cycles variation)
we have, SWPadnos and elmo40 here thats has interrest on Avr development
alexis_4315: EMC + RTAI is working with ArchLinux if you need a small image
unless you have critical sections with interrupts disabled all over the place, or you're servicing multiple interrupt sources
I have little interest in AVR development for EMC, but I've been writing AVR software since they released the AT90S1200
alexis_4315: this might be current http://neo-technical.wikispaces.com/emc2-arch
a little interest in AVR development... do not stop you on thinking of it, u just dont admit it. AVR32 is a 32bit system
L84Supper thanks! im on my way
some people are looking into EMC2 on (2-4 core) ARM soc's with PCIe, not sure how that will end up yet
#avr32 still has few member ...couple month from now perhaps
ARM... no...its has to be avr ...AT32AP7000 has 150MHz
but <SWPadnos> says AVR1 is a enought
has it possibelity
<SWPadnos> and after all the optimization in the world, an AVR at 20 MHz still has 10x better latency
10x is good
2-4 core ARM tablet with PCIe for I/O and motion boards could make for a nice touch screen user interface
if u need touch screen... u can do it on archlinux today
my point wasn't about touchscreen support by the OS
anyone ever used freescale stuff?
atmega: imx arm soc's?
freescale > $15 ?
I designed some tablets using them
there is a freescale prototyping seminar nearby, but I couldn't make it
WOW, design a tablet! VERY interresting
atmega: everything is supported well in Linux except for the PowerVR gpu
PowerVR only has closed binary blobs
what series of freescale on low-price u suggest
alexis_4315: depends on the features needed, no PCIe with Freescale
at least with ARM
take a look and see how many months it will take to get emc2 on the arm version
or Debian armel
well, many ARM today became a tablet and notebook ...even VIA became PC (as it processor)
linux would attach on them easily
and do some liveCD on via processored PC
so, its today.
VIA PC + liveCD + PCI-Mesa... you re o
(my keyboards jams)
ARM PC+LiveCD+PCI-Mesa +LCD touchable its today
LCD touchable to replace mouse
rtai is the man
why search more expensive system than this?
...you dont really want rtai on your palm-pilot, is your inner feeling.
or a tablet
huge cnc vs pc is okey today
we found out our cheap dial indicator was off about .010 over 1 inch :)
that's pretty impressive
I always worry when I see people setting scales using those import 1" or 2" indicators
post the make and supplier so we all can get one
25466? are you suuure?
new out of the box one was off .001 - but we might not have had perfectly perpendicutlar
those are the wrong tool for measuring distances
dti and two gage blocks wrung to make a step
we got out our trusty 4' vernear caliper.
heh I'd use a 4" gage block instead of a 4' caliper :-)
WOW a four foot caliper
proportionally those are probably similar precision
I have no clue what brand the dial indicator was - probably enco
that wasn't the .0001 indicator was it? (those don't usually have a full inch...)
that one is a bit better quality
not a high bar
cradek: what is a dti?
[16:18:07] <cradek> http://www.qwikfast.co.uk/catalogue/images/silvdialtestindica783110.jpg
dial something indicator?
this kind is what I mean
I call them test indicators for some reason I don't know
you'd come from one side to the end of the long gage block, finding zero on the dial, touch off, lift just enough to hit the block wrung to the other end, move to the same zero on the dial
I think you could get a real .0002ish reading this way
well maybe that's optimistic :-)
pretty sure it's the best I could do with tools at my disposal, anyway
I was trying to find some reflective tape to use our rpm meter - to be able to set the y axis servo's drive scaling initally. then dad said - 'can't you use the encoder and emc for that?' ;)
it was actually pretty easy of I did it right - I just set the axis input scale to (encoder lpr*4)/60. than halmetered the encoder velocity.

alexis_4315: RTAI already works on some TI OMAP ARM (exp the one on the Beagleboard.org), there is also some work going on with Marvell Arm

Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-10-05.txt
atmega, did you catch the post for vectric stuff?
atmega, see http://filebin.ca/vtfmus/EMC2_arc_inch.pp
skunkworks, yea very nice.... time to make some big blue chips!
Lawrence: thanks, I found a PP file for it in the v-carve demo install
I'm still not convinced that there is anything I want to cut where it is quicker to use CAM stuff than just write it
atmega, cheers ...
LawerenceG: do you use vectric stuff?
my buddy has a copy of vcarve and I have done a few projects with it..... Its not bad for windows software! seems to make OK code
Do you know if there is a way to set max z height? The initial Z I get is outside my limits
probably in a one of the setup screens or maybe the tool screen... I sometimes edit the code and put paths in emc subroutines and things like the clearance positions in emc2 variables to make the code more reusable
that would be good... Do you know if it will do incremental Z cuts?
yes it will (assuming you mean multiple passes in a pocket)
I wanted mulitple passes in a profile
you specify the depth increment
I could break down and by a copy, but I have an aversion to paying for things.
if you edit the tool properties, there is a cutting parameter for pass depth and one for step over
I've just used the demo versions. It seems like it would be useful if it knew some basics of the machine being targeted (max rates, travel limits, etc)
when you set up a job, you define the workpiece LxWxH ... that keeps things pretty much under control
oh yeah... I didn't really see that since I could only work with the demo files and they were already set up
skunkworks: Congrats on the Y axis, looking good. BTW, I didn't know (or forgot till you posted the new Y photos and helix video) that your Y motor shaft and the new adapters aren't vertical. So there must be a right angle drive in there somewhere?
KimK: funny you should ask... http://electronicsam.com/images/KandT/conversion/yaxis/Ygears.jpg
we took the access cover off of the other y axis to count the gears. (so we could get an acurite scale.

Just fitted a Newall Microsyn 10 3 axis dro to my Balding Beaver Mill. It's been sitting in storage for six months :-)
[20:51:29] <Paragon39> http://www.newall.com/technology/
Clever they way they use ball bearing to measure linear movement...
thats how all the old resolvers work isnt it?
Not too sure Valen I know they cost a small fortune. I think the laser cut glass scale dro's are much cheaper. I picked up the 3 axis's Micorsyn 10 for around 400 UKP second hand via ebay and there was around 30 bids after it from memory!
I am also of the understanding the newall scales are very robust in harsh enviroments were the glass scales may not fare so well.
This is the mill I fitted the scales to ... http://www.lathes.co.uk/beaver/page2.html
I think they had a sense of humour calling it a Balding Beaver ;-)
coo, is this thing on?
wow so many people these days .. either its popular, or people forgot to leave ...
can't stay away?
well, you know how it is :)
hows the world of robotic welding?
we have been thinking about doing some of that ;->
sticking our TIG into the mill to do some precise stuff
its fun, just buy and old ABB robot
easy to programme
you in the UK?
we were going to mount it in our mill
soon to be 4 axis
Folks could you remind me what I need to add to ./configure for run in place?
might be OK with tig
the UV might rot stuff
the odd bit of spatter might not be good ...
Thanks SWPadnos I forgot the enable part ;-)
you can get a secondhand robot for $1000 AUD
[23:06:19] <Paragon39> http://wiki.linuxcnc.org/emcinfo.pl?Installing_EMC2
does not mention the --enable-run-in-place directive.
Has anyone heard from Jepler latley?
Paragon39: it's the default lately
so you don't need to write it explicitely
robin_sz: going pretty slow atm
just the way of the world im afraid
yeah, well.. we'll get over it I hope ;)
i didn;t :)
no more stamps?
oh thats OK
robin_sz: not planning on doing it 4/7
Oh I didn't realise alex_joni thanks for the info!
no more welding / cutting
robin_sz: too bad, you had some nice machines
nah its fine
I have time to go sailing now :)
that's all that matters really
had 3 weeks on holiday in france
provence, near lac st croix
piccies coming in pm
I think I have either blown my Pluto-p card or the Paraport! Strange thing is is uploads and connects using fpga4fun uploader but errors when insmod pluto_step.ko is executed :-(
Can anyone assist with the procedure for installing the binaries rtai-modules-2.6.24-16-rtaismp ?
How does the 7i43 fare driving steppers?
only ever used it for servos, but .. given that the analogue out for servos is produced by low pass filtering a high speed PWN signal, I should think it will have no trouble at all
I am certainly concidering the 100usd investment is there anything else that I would need to buy I've notive folks mention the 7i49 (from memory) what benifit would this give me ie 7i43 + 7i49?
I think my Pluto-P is screwed! gettin a Failed to communicate with pluto-servo board after programming firmware
dunno about 7i43 but hostmot2 has configurations for steppers if you chose that config
hmm, im probably not the best person to ask
I am soon(hopefully) to use it to mix servos and steppers on ours
mine has been sitting idle for a bit
