03:16 PM * Tom_L kicks it in the pants
03:21 PM Tom_L: power blinked yesterday, maybe that did it
03:21 PM Tom_L: my irc died but the pc didn't reboot either
03:36 PM Tom_itx: ping
03:36 PM Tom_itx: ok, that's better
03:42 PM Tom_itx is now known as Tom_L
03:50 PM XXCoder: pink_vampire: worked?
03:54 PM justan0theruser is now known as justanotheruser
04:00 PM pink_vampire: yes, it is working now, i'm getting 1mm per rev
04:01 PM XXCoder: nice! though i guess you eveenually want to make or buy that gear?
04:02 PM pink_vampire: it is seams very strong
04:04 PM XXCoder: interesting. pla can be pretty strong but bit brittle
04:04 PM pink_vampire: hope it will work for few parts
04:11 PM XXCoder: yeah
04:18 PM Loetmichel: ah, btw: just found out that the reason for the bsod last week wasnt the heatsink at all... had another one this morning and it said something about disk not found... and after reboot the SSD i used for the swap file was gone from the disk list... seems it isnt a good idea to buy "noname" ssds. didnt even live a year... :-(
04:22 PM pink_vampire: yeah, ssd don't last forever
04:22 PM pink_vampire: https://i.imgur.com/W1FiRO3.png 100% infill
04:33 PM _unreal_: There my motor contorller interface boards have been cut in half and I now have my four
04:34 PM _unreal_: pink_vampire, is that a 2 speed?
04:34 PM _unreal_: or just for a different pitch control
04:37 PM _unreal_: Oh and I noticed its pink :)
04:37 PM Rab: pink_vampire, might be time for a combination of white + red lithium grease. :P
04:38 PM * _unreal_ about what kind of grease white and red linthium would produce
04:38 PM * _unreal_ ponders
04:39 PM Loetmichel: _unreal_: the right one for pink_vampire ;)
04:39 PM pink_vampire: it is just to do threading
04:39 PM pink_vampire: I love the pink filament
04:40 PM Loetmichel: pink_vampire: looks like the gears on a lathe for thread cutting
04:40 PM pink_vampire: there is an option for power feed
04:46 PM _unreal_: OMG OMG OMG OMG, I just scorred back row seats at the imax for avengers end game tonight
04:47 PM _unreal_: SWEEET
04:47 PM * _unreal_ grabs a beer
04:48 PM _unreal_: heh I was putting my info in using fandango and it gave me a 4min timer for the seat reservation while I was putting my CC info in
04:48 PM _unreal_: I was like WHAAAAAA
04:49 PM andypugh: Ah, it seems that this laptop disocnnects when it snoozes
04:50 PM andypugh: Did I miss much?
04:51 PM _unreal_: andypugh, everything
04:51 PM andypugh: Oh no!
04:52 PM _unreal_: andypugh, I mean where were you... pink_vampire showed a photo of her pink gear and everything
04:52 PM _unreal_: Loetmichel, and he prob thinks I'm kidding to...
04:52 PM andypugh: Did it work?
04:52 PM andypugh: No, I can’t imagine PV printing a gear in any other colour
04:53 PM pink_vampire: andypugh: yes,i'm getting 1mm per rev
04:53 PM andypugh: Do you have an M6 x 1mm tap? You can use that as a threading tool in the toolpost.
04:53 PM pink_vampire: andypugh: the test gear was silverish gray
04:54 PM pink_vampire: i don't have stock
04:54 PM _unreal_: so at this point I have a few people co working on helping to get this tinkerboard cnc project going.
04:54 PM andypugh: Using taps as internal threadi forming tools on a lathe works well, even if it does feel naughty
04:55 PM andypugh: _unreal_: Where have you got up to?
04:56 PM _unreal_: RT is working great, linuxcnc is built many moduals are built. the onlything that is on the chopping block right now is getting the HAL/GPIO up and running
04:56 PM _unreal_: thats the big one
04:56 PM pink_vampire: each fastenal branch take other fee for pickup in the branch
04:56 PM pink_vampire: WTF
04:57 PM gambakufu: _unreal_, what kind of latency are you getting?
04:57 PM _unreal_: pink_vampire, sounds like a pyramid scheme
04:58 PM _unreal_: the base 25ms linuxcnc_test gives 18,000 to 22,000 under load
04:58 PM _unreal_: and thats totally stock install of armbian built for the tinkerboard with any an all extra BS software running
04:58 PM _unreal_: and no tuning
05:00 PM _unreal_: the next step is getting the GPIO_HAL working. When that is working and it becomes a usable system to drive steppers directly. its going to be an amazing system consdiering the non S version tinkerboard boards go for $50-60 on average
05:00 PM _unreal_: and they are 2x the cpu power of the RPI
05:10 PM andypugh: hal_gpio uses the Linux interface?
05:11 PM _unreal_: ahh
05:11 PM _unreal_: I'm not really sure how to answer that
05:12 PM _unreal_: as I understand it, it needs to be mapped to/as a memory location. other wise it will introdce a lot of latency
05:14 PM andypugh: There was a generic driver, and that seems worth a try
05:15 PM _unreal_: I'm not a programmer
05:16 PM _unreal_: I mean I can kind of read arduino I'm not much of an arduino programmer but much past that I get lost fast
05:16 PM andypugh: I wan’t a programmer until I started writing drivers for the Mesa cards :-)
05:17 PM andypugh: I would expect https://github.com/machinekit/machinekit/blob/master/src/hal/drivers/hal_gpio.c to be very close, just needing some constants changingp, probbaly.
05:17 PM _unreal_: andypugh, I'm suprised I have not seen a mesa card designed as a HAT for the RPI form factor
05:18 PM andypugh: There is one in development.
05:18 PM _unreal_: andypugh, the next time you see fdarling I'd suggest talking to him. he's one of the people helping me with this part of the project
05:19 PM _unreal_: Though I main goal right now is to have the GPIO's them selfs available for software control. Rather then requireing a hardware interface
05:19 PM _unreal_: meaning a MESA card
05:20 PM andypugh: http://www.mesanet.com/fpgacardinfo.html 7C80 and 7C81
05:22 PM _unreal_: wow I must be drunk? and I'm jsut starting my second beer?
05:22 PM _unreal_: though my main
05:27 PM _unreal_: andypugh, I still dont plan on using any kind of an FPGA board unless I have to.
05:27 PM _unreal_: and from what I have seen from the basic tests I'm not going to.
05:28 PM andypugh: I seem to recall discussing a generic driver or these boards. using mmap. But can’t remember where it was
05:28 PM _unreal_: My history only goes back 4k lines
05:28 PM _unreal_: nope no history of mmap
06:04 PM andypugh: Tomorrow I will be using my smallest boring bar.
06:05 PM andypugh: It can bore holes 1.6mm dia
06:35 PM pink_vampire: andypugh: pics or didn't happen
06:41 PM andypugh: Page A60 here shows one that can bore holes 0.17mm dia! https://www.phorn.co.uk/catalogue/download/superminir-mini-4/
06:41 PM andypugh: I don’t know why you would need to…
06:45 PM XXCoder: man I'd love that for certain part.
06:45 PM XXCoder: hole is 1.2mm something but over half inch deep
06:45 PM XXCoder: we use special taps for it, and cleaning swarf out is annoying as hell
07:03 PM andypugh: XXCoder: I have dozens of them, not down sub-mm but I probably have one that can do 1.3mm. I have a search on eBay.
07:04 PM XXCoder: cool :)
07:04 PM _unreal_: wtf how big is that file?
07:05 PM andypugh: https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=horn+supermini&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=horn+B105&LH_TitleDesc=0
07:05 PM _unreal_: bbiab taking a shower
07:06 PM andypugh: _unreal_: 37MB
07:06 PM andypugh: But I have fast broadband so it takes about 1 second.
08:05 PM _unreal_: well that was fun NOT..... I just got a frantic call from my neighbors. they are elderly and the wife was at the store called me to come over her husband was dizzy. He tried to transfer from one location to an other with me and moved to fast and I ended up having to help him to the ground. just took off in the ambulance.
08:09 PM _unreal_: andypugh, was more of a WHAT THE HELL jumbo pdf file
08:11 PM andypugh: But it’s a jumbe file of lovely carbide things
08:12 PM _unreal_: I see and 99.9% of them i'm sure I will likely never use in my life :(
08:13 PM Tom_L: cannot have too many of those around for sure
08:13 PM _unreal_: I would guess a lot of those are used for injection molding tooling
08:14 PM _unreal_: !@#$@##$ oh crap I dont know where my glasses are
08:14 PM _unreal_: got to leave for the movie in less then an our
08:14 PM _unreal_: hour
08:15 PM _unreal_: found them
08:16 PM _unreal_: its wierd, my eyes are so messed up I see better with out them unless I'm driving.
08:16 PM _unreal_: didnt use to be so bad till the random mac degeneration started
08:17 PM andypugh: I am finding that my eyes work less well on the 11” laptop screen than on the 27” desktop screen. But the desktop died today.
08:17 PM _unreal_: now I have bubbles that come and go.... and there is nothing that can be done about it.
08:18 PM _unreal_: oddly enough I have no DEAD spots. I was told I was going to have large black dead areas and I did for a while then they recovered. but I have horrid bubbles.
08:19 PM andypugh: I am taking the iMac to the shop or them to look at tomorrow. I am rather expecting to come home with a brand-new one and a hole in my bank account.
08:19 PM andypugh: But at least I can do that. I don’s suppose that you can easily buy new eyes.
08:19 PM andypugh: Well, not that can be fittted and work, anyway. Buying eyes is probably quite easy.
08:20 PM _unreal_: anything thats about 12" in front of my face I can see as if nothing was wrong, byond that blaaaaaaa. BUT if I have my glasses on and watch a "3D movie" I can see it fine. something to do with the 3d glasses changes the focal point I guess???? and I have almost NO miss alinged areas
08:20 PM _unreal_: andypugh, I ment to mention to you before
08:20 PM _unreal_: about the mac
08:20 PM _unreal_: have you seen the guy on youtube that does the MAC repair?
08:21 PM _unreal_: 90% of the MACs dieing are due to single TINY parts failing and its like $100 repair vers $3k to """ replace """
08:23 PM andypugh: Well, yes. But that isn’t just a Mac thing
08:24 PM andypugh: But the problem, always, is working out which tiny thing it is
08:24 PM _unreal_: https://www.youtube.com/channel/UCl2mFZoRqjw_ELax4Yisf6w
08:24 PM _unreal_: That guy
08:24 PM _unreal_: one of a few examples not JUST that guy
08:25 PM _unreal_: cant hurt to at least contact one of those mac repair places
08:28 PM andypugh: I eel short of time.
08:28 PM andypugh: (feel)
08:29 PM andypugh: I I had nothing else on, I would be inside it already. It has an SSD where the HD used to be, I am not scared to go inside them.
08:30 PM andypugh: I had a G4 cube a while ago, and to it an upgraded graphics card I moved some PSU components to the other side of the board.
08:30 PM andypugh: So I probably could ix it, but without it every other project is on hold.
08:31 PM andypugh: (I was doing CAD for one of my projects when it died..
08:51 PM skunkworks: I just ran a mill with rt_preempt and the printer port.. 200ipm at 10000 steps per inch
08:52 PM * skunkworks waits for everyone to convert to metric
09:06 PM _unreal_: later leaving for the movie :)
09:10 PM * Tom_L watches skunkworks grow old waiting
