12:42 AM Loetmichel: jut needs to face off both sides about 0,2mm deep
12:47 AM Loetmichel: no holes drilled, that stuff is like a sponge, it lets air thru. and the fibres grab parts real good
12:47 AM Wolf__: well, I guess the stack of dell 745 with the note marked “trash” on them wasnt too bad of a find
12:47 AM Loetmichel: core 2 duo?
12:47 AM Loetmichel: quite old...
12:47 AM Wolf__: yup, E4400 2ghz w/ 2gb ram
12:47 AM Wolf__: and AMD/ATI RV516 vid cards, 6 of them, powered up 2 so far, lucky part is the first one I opened up had the DMS-59 cable in it
12:47 AM * Loetmichel main PC still has an I7-920 in it... and thats QUITE old now...
12:47 AM Wolf__: tossed a lcnc 27. something cd in it and ran a quick test and it was hitting around 45k
12:48 AM Loetmichel: bios, all Power related interrups/options -> off
12:48 AM Wolf__: oh right, I didnt even think to check that crap lmao
12:49 AM Loetmichel: it IS ok for mesa cards
12:49 AM Loetmichel: i am oldschool... and use LPT ports ;)
12:49 AM Wolf__: yeah I was thinking of using them for a couple simple LPT builds, seeing that they actually have them lmao
12:49 AM Loetmichel: my mill at home has a c2d 2,8ghz, too
12:49 AM Loetmichel: works perfect
12:50 AM Wolf__: price was right, free
12:50 AM Loetmichel: but an industrial (kontron) board, not dell hardware
12:50 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12250
12:50 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12247
12:50 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12265
12:51 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12533&g2_imageViewsIndex=1
12:51 AM Loetmichel: :-)
12:51 AM Loetmichel: no space in that rack, had to build small
12:51 AM Loetmichel: that pizza box had a 268-board in it ;)
12:52 AM Loetmichel: 286
12:52 AM Loetmichel: soo, now off to work
12:52 AM Wolf__: lol I remember those…
02:07 AM Deejay: moin
04:37 AM Loetmichel: any welders here? just got an offer for an Stahlwerk AC/DC TIG welder, 10A-200A... upgrade to the DC-WIG-200-ST-IGBT-Puls. will be aviable in 4 weeks... any idea if that will be good for 1-1,5mm Alu sheet material? (edges of enclosures)
04:46 AM Tom_L: morning
04:57 AM miss0r: morning tom - did you see the pictures I posted last night?
05:01 AM Tom_L: nope, i missed those
05:02 AM miss0r: https://imgur.com/a/v3LLr70 <- the shaper head I'm working on
05:03 AM miss0r: A few more things have been added today - no photos yet though ;)
05:04 AM Tom_L: nice job
05:04 AM Tom_L: steel block?
05:05 AM miss0r: ductile iron
05:05 AM miss0r: so you can imagine what a mess it is to work with
05:06 AM Tom_L: well it didn't look like aluminum but the shavings weren't quite steel looking either :)
05:06 AM Tom_L: guess the rougher does that to em
05:06 AM miss0r: yeah
05:07 AM miss0r: only cutter I had, I could push to do 100mm deep work
05:07 AM Tom_L: i'd have a hard time with that on my little mill
05:07 AM Tom_L: looks good
05:09 AM miss0r: Thanks.
05:09 AM miss0r: Its alot of work on my mill as well.
05:09 AM miss0r: its not exactly new anymore :)
05:10 AM Tom_L: 40 taper?
05:10 AM Tom_L: looks like it anyway
05:10 AM miss0r: yeah
05:10 AM Tom_L: good size mill
05:11 AM miss0r: yeah.. 30 is on the wee bit small size.. 50 or 60 is too big
05:32 AM jthornton: morning
05:33 AM XXCoder: hey
05:36 AM jthornton: got 2 of 3 web sites transferred now for the main one
07:31 AM Loetmichel: ah, btw: someone wanted to know how the Files are mounted into the handles... found the darn square nuts and grub screws: ->http://www.cyrom.org/palbum/main.php?g2_itemId=17541&g2_imageViewsIndex=1
07:49 AM gregcnc: loetmichel know anything about kontron slot cpu?
09:17 AM JT-Shop: wonderful, right in the middle of printing a shipping label I get the blue screen of death
09:30 AM Loetmichel: gregcnc: depends which one
09:31 AM gregcnc: super odd circa 2003 https://www.rgbautomatyka.pl/en/p7-slot-cpu-9-1101-9003-roi-computer-kontron-id21771.html
09:31 AM gregcnc: i'm about to put power to it, just checking the power supply
09:35 AM Loetmichel: you'll need the fitting backplane to power it
09:36 AM gregcnc: hm power_ok on this atx psu is not going high
09:36 AM gregcnc: this is in an Emco machine
09:36 AM Loetmichel: only the 12V for the CPu is on the board, the otehr ATX voltages are going into the backplane
09:36 AM Loetmichel: use another PSU, old ATX psus tent to have leaky electrolytics and then dont give "PG"
09:37 AM Loetmichel: tend
09:37 AM gregcnc: flex atx pinout the same as normal?
10:09 AM Loetmichel: yes
10:12 AM Loetmichel: *GNHIHIHI* 17:00... Coworker cleans up his desk and runs for the the stamp clock... havent seen him move THAT fast all day ;)))
10:45 AM gregcnc: no luck. either backplane or MB is dead
10:45 AM gregcnc: though USB and keyboard lit up
11:08 AM Loetmichel: gregcnc: did you connect the 12V for the cpu?
11:09 AM gregcnc: yes, power OK goes low with backplane plugged in
11:10 AM Loetmichel: and the backplane is the right PCIMG standard for the board?
11:10 AM Loetmichel: there are differences, and IIRC not all have different slots
11:11 AM gregcnc: i'm sure it's all original
11:11 AM Loetmichel: ok then
11:11 AM Loetmichel: was a thought
01:08 PM gregcnc: Loetmichel turns out this won't boot with a dead cmos battery and it's an ROI
01:08 PM Loetmichel: ROI?
01:09 PM gregcnc: roi computer ag
01:38 PM gregcnc: it booted! now to put power to the machine to see if it talks to the control
01:46 PM FinboySlick: Any of the more electronics-savvy people here know if it's possible to remap sectors on a failing SanDisk eMMC chip?
01:47 PM FinboySlick: I'm not equipped to repair BGA chips and I don't need the whole card's capacity.
01:57 PM sync: you can try to dd in all zeros
01:58 PM sync: but if you already got bad blocks, I'd just get a new emmc
02:03 PM SpeedEvil: FinboySlick: The EMMC managment is on-chip and you can't bypass it AIUI
02:06 PM FinboySlick: sync: It's soldered-on and I don't have the technical ability to replace it.
02:07 PM FinboySlick: SpeedEvil: mmc status get /dev/mmcblk0 -> SEND_STATUS response: 0x00000900
02:07 PM FinboySlick: I'm not sure what that means.
02:22 PM sync: then I guess have somebody who does replace it?
02:22 PM sync: but apart from writing zeros to it and hoping that the controller remaps the sector you are out of luck
03:35 PM Deejay: gn8
04:27 PM gregcnc: powered up the machine and everything works. appears a bad psu and cmos battery in the PC did this Emco in
04:27 PM CaptHindsight: \0/
04:31 PM gregcnc: i'm amazed, but never heard of a computer that wouldn't boot with a dead cmos battery
04:35 PM gregcnc: I didn't try. supposedly, if you take the battery out it will boot. it's soldered to the board
04:43 PM _unreal_: wonderful
04:44 PM _unreal_: a project I finished some time ago I have to redo now for work bcause they gave me the wrong schematic
04:50 PM CaptHindsight: gregcnc: it is common where the BIOS has no self check for memory or default for core multiplier
04:51 PM CaptHindsight: BIOSes are pretty crappy, they are faith based firmwares
04:51 PM gregcnc: that must be it. it wants to to set the multiplier and I have no idea what it should be
05:27 PM CaptHindsight: gregcnc: unless they hard code it (which is rare) it has to know the cpu core multiplier, type, size and speed or memory (arrangement) etc
