[01:35:27] <miss0r> goodmornings
[01:36:27] <Loetmichel> _unreal_: do you use coolant?
[01:36:48] <Loetmichel> if not: try a sheet of 5mm MDF as a topping of your vacuum table
[01:36:51] -!- c-log has joined #linuxcnc
[01:37:18] <Loetmichel> jut needs to face off both sides about 0,2mm deep
[01:37:51] <Loetmichel> no holes drilled, that stuff is like a sponge, it lets air thru. and the fibres grab parts real good
[01:37:58] <Wolf__> well, I guess the stack of dell 745 with the note marked “trash” on them wasnt too bad of a find
[01:38:25] <Loetmichel> core 2 duo?
[01:38:30] <Loetmichel> quite old...
[01:38:53] <Wolf__> yup, E4400 2ghz w/ 2gb ram
[01:40:19] <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
[01:40:31] * Loetmichel main PC still has an I7-920 in it... and thats QUITE old now...
[01:41:04] <Wolf__> tossed a lcnc 27. something cd in it and ran a quick test and it was hitting around 45k
[01:41:25] -!- c-log has quit [Ping timeout: 268 seconds]
[01:41:26] <Wolf__> so might be ok for some cnc boxes =D
[01:41:35] <Loetmichel> hmm
[01:41:43] <Loetmichel> might wanna optimise that a bit
[01:42:15] <Wolf__> should be ok for running mesa cards
[01:42:21] <Loetmichel> http://www.cyrom.org <- when a p4 can do a quarter of that ;)
[01:42:34] <Wolf__> any suggestions on how to optimise
[01:42:56] -!- c-log has joined #linuxcnc
[01:43:02] <Loetmichel> bios, all Power related interrups/options -> off
[01:43:19] <Wolf__> oh right, I didnt even think to check that crap lmao
[01:43:20] <Loetmichel> it IS ok for mesa cards
[01:43:29] <Loetmichel> i am oldschool... and use LPT ports ;)
[01:44:07] <Wolf__> yeah I was thinking of using them for a couple simple LPT builds, seeing that they actually have them lmao
[01:44:11] <Loetmichel> my mill at home has a c2d 2,8ghz, too
[01:44:16] <Loetmichel> works perfect
[01:44:31] <Wolf__> price was right, free
[01:44:35] <Loetmichel> but an industrial (kontron) board, not dell hardware
[01:44:59] <Loetmichel> http://www.cyrom.org
[01:45:05] <Loetmichel> http://www.cyrom.org
[01:45:10] <Loetmichel> http://www.cyrom.org
[01:45:32] <Loetmichel> http://www.cyrom.org
[01:45:35] <Loetmichel> :-)
[01:45:57] <Loetmichel> no space in that rack, had to build small
[01:46:14] <Loetmichel> that pizza box had a 268-board in it ;)
[01:46:20] <Loetmichel> 286
[01:46:34] <Loetmichel> soo, now off to work
[01:46:36] <Wolf__> lol I remember those…

[05:31:40] <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)
[05:40:40] <Tom_L> morning
[05:46:30] -!- selroc has quit [Quit: Leaving]
[05:51:47] <miss0r> morning tom - did you see the pictures I posted last night?
[05:56:07] <Tom_L> nope, i missed those
[05:57:12] <miss0r> https://imgur.com <- the shaper head I'm working on
[05:57:48] <miss0r> A few more things have been added today - no photos yet though ;)
[05:59:04] <Tom_L> nice job
[05:59:10] <Tom_L> steel block?
[05:59:45] <miss0r> ductile iron
[06:00:07] <miss0r> so you can imagine what a mess it is to work with
[06:00:26] <Tom_L> well it didn't look like aluminum but the shavings weren't quite steel looking either :)
[06:00:44] <Tom_L> guess the rougher does that to em
[06:01:08] <miss0r> yeah
[06:01:27] <miss0r> only cutter I had, I could push to do 100mm deep work
[06:02:00] <Tom_L> i'd have a hard time with that on my little mill
[06:02:13] <Tom_L> looks good
[06:03:29] <miss0r> Thanks.
[06:03:35] <miss0r> Its alot of work on my mill as well.
[06:03:45] <miss0r> its not exactly new anymore :)
[06:04:42] <Tom_L> 40 taper?
[06:04:49] <Tom_L> looks like it anyway
[06:04:50] <miss0r> yeah
[06:05:03] <Tom_L> good size mill
[06:05:24] <miss0r> yeah.. 30 is on the wee bit small size.. 50 or 60 is too big

[10:12:09] <JT-Shop> wonderful, right in the middle of printing a shipping label I get the blue screen of death
[10:24:58] <Loetmichel> gregcnc: depends which one
[10:25:24] <gregcnc> super odd circa 2003 https://www.rgbautomatyka.pl
[10:25:50] <gregcnc> i'm about to put power to it, just checking the power supply
[10:30:12] <Loetmichel> you'll need the fitting backplane to power it
[10:30:22] <gregcnc> hm power_ok on this atx psu is not going high
[10:30:34] <gregcnc> this is in an Emco machine
[10:30:39] <Loetmichel> only the 12V for the CPu is on the board, the otehr ATX voltages are going into the backplane
[10:31:16] <Loetmichel> use another PSU, old ATX psus tent to have leaky electrolytics and then dont give "PG"
[10:31:25] <Loetmichel> tend
[10:31:47] <gregcnc> flex atx pinout the same as normal?

[11:38:26] -!- CNC_Brian has joined #linuxcnc
[11:39:24] <gregcnc> no luck. either backplane or MB is dead
[11:39:41] <gregcnc> though USB and keyboard lit up
[11:48:04] -!- ziper has joined #linuxcnc
[12:03:17] <Loetmichel> gregcnc: did you connect the 12V for the cpu?
[12:03:53] <gregcnc> yes, power OK goes low with backplane plugged in
[12:04:33] <Loetmichel> and the backplane is the right PCIMG standard for the board?
[12:04:51] <Loetmichel> there are differences, and IIRC not all have different slots
[12:05:25] <gregcnc> i'm sure it's all original
[12:05:47] <Loetmichel> ok then
[12:05:50] <Loetmichel> was a thought

[14:32:23] <gregcnc> it booted! now to put power to the machine to see if it talks to the control
[14:41:17] <FinboySlick> Any of the more electronics-savvy people here know if it's possible to remap sectors on a failing SanDisk eMMC chip?
[14:41:59] <FinboySlick> I'm not equipped to repair BGA chips and I don't need the whole card's capacity.
[14:51:50] <sync> you can try to dd in all zeros
[14:52:21] <sync> but if you already got bad blocks, I'd just get a new emmc
[14:58:01] <SpeedEvil> FinboySlick: The EMMC managment is on-chip and you can't bypass it AIUI
[15:01:03] <FinboySlick> sync: It's soldered-on and I don't have the technical ability to replace it.
[15:02:02] <FinboySlick> SpeedEvil: mmc status get /dev/mmcblk0 -> SEND_STATUS response: 0x00000900
[15:02:13] <FinboySlick> I'm not sure what that means.
[15:03:53] -!- gloops has quit [Quit: Leaving]
[15:16:28] <sync> then I guess have somebody who does replace it?
[15:16:45] <sync> but apart from writing zeros to it and hoping that the controller remaps the sector you are out of luck

[17:21:55] <gregcnc> powered up the machine and everything works. appears a bad psu and cmos battery in the PC did this Emco in

[17:25:29] <gregcnc> i'm amazed, but never heard of a computer that wouldn't boot with a dead cmos battery
[17:29:58] <gregcnc> I didn't try. supposedly, if you take the battery out it will boot. it's soldered to the board
[17:38:13] <_unreal_> wonderful
[17:38:28] <_unreal_> a project I finished some time ago I have to redo now for work bcause they gave me the wrong schematic
[17:45:13] <CaptHindsight> gregcnc: it is common where the BIOS has no self check for memory or default for core multiplier
[17:45:47] <CaptHindsight> BIOSes are pretty crappy, they are faith based firmwares
[17:46:08] <gregcnc> that must be it. it wants to to set the multiplier and I have no idea what it should be
