01:52 AM Deejay: moin
01:58 AM pink_vampire: hi
03:31 AM hazzy-m: we just had an earthquake here in Atlanta George, did any of y'all notice it too? Wonder how wide spread it was. It was shaking pretty good
03:34 AM MarcelineVQ: I'm a little fuzzy on the geography there but that strikes me as a rare thing yeah?
05:04 AM Tom_L: hazzy-m, which is worse an earthquake or a sprinkling of snow?
05:07 AM XXCoder: both
05:07 AM Tom_L: we haven't had one for a while but i think they're cracking down on fracking around here
05:07 AM XXCoder: fracking fracking.
05:08 AM Tom_L: the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc., so as to force open existing fissures and extract oil or gas.
05:08 AM XXCoder: yeah im using that word as curse word also
05:09 AM Net|: https://www.thingiverse.com/thing:3278377 started an automatic dvd burner
05:23 AM jthornton: morning
05:23 AM XXCoder: hey jt
05:30 AM XXCoder: they finally got rid of okuma at work
05:31 AM jthornton: was it a bad one to run?
05:33 AM XXCoder: sorta. mostly its fine but programs have to be made unsafe in some cases because it would error out of it changes from tool to same tool
05:33 AM XXCoder: yeah just oignore it and start milling man.
05:41 AM XXCoder: such a strange setup caused tools to get crashed once a while
05:47 AM jthornton: damn mouse or something is eating the wheat from the trap area but not stepping in the glue traps wtf they surround the bait
05:49 AM XXCoder: make some of those multi-mouse traps
05:49 AM XXCoder: https://www.youtube.com/watch?v=FPSlzg-oqoo
05:50 AM XXCoder: glue types really suck
05:50 AM jthornton: they usually work great for me but this guy is not stepping in the trap
05:50 AM XXCoder: im not saying it "doesnt work" sucjk
05:51 AM XXCoder: it sucks on mouses suffer with em. just kill em quick
05:52 AM jthornton: I do kill them quick by breaking their neck
05:53 AM XXCoder: yeah once you get to trao
05:57 AM jthornton: I also have spring traps in the same place but they are not touched either... time for the game camera to see what I have
05:57 AM XXCoder: the video I linked to is really simple to make
05:57 AM XXCoder: and boy does he hate glue traps lol
05:57 AM XXCoder: he always do either release or dead by trap, never "middle"
06:04 AM jthornton: that looks easy to make
06:04 AM XXCoder: yeah
06:04 AM XXCoder: he even made 3d printable versions of it
06:06 AM MarcelineVQ: the neat part about it is you can try different baits in each bay to see what they're after more
06:06 AM XXCoder: marc and mouse has no problems going after food between 2 dead mouses.
06:06 AM jthornton: that's a good idea
06:07 AM XXCoder: its like theres a table with 2 dead guys facedown on food. in middle theres another plate of food, fresh
06:07 AM XXCoder: sure lets eat it
06:08 AM MarcelineVQ: saw a gray rat in my woodpile today, haven't seen a gray one here before
06:08 AM XXCoder: good thing mouse isnt too smart
06:08 AM XXCoder: jthornton: other video of his, ALL holes got full of mouse
06:09 AM jthornton: did he say what bait he used?
06:09 AM MarcelineVQ: probably the cob from the bag he gets his strings from :>
06:09 AM XXCoder: hmm dont really recall. nuts and stuff? I tend to use peanut butter
06:10 AM MarcelineVQ: for rats I use a little cob, some sugar bits, some dry cat food, and peanut butter to glue them into the trap, cover my bases
06:11 AM jthornton: cob?
06:11 AM MarcelineVQ: corn oats barley, crushed grains basically
06:12 AM jthornton: this one has been munching on wheat for the last several days but ignores the peanut butter on the spring traps
06:51 AM jthornton: looks like rain Thursday and Friday here
06:52 AM XXCoder: looks like unending rain of doom here
06:52 AM XXCoder: what time rain appears varies but no no rain day
06:52 AM XXCoder: it's when bunch of people move out of washington
06:52 AM XXCoder: or in least move towards east
06:55 AM XXCoder: oh wow
06:55 AM XXCoder: news from rayton
06:55 AM XXCoder: i invested in that company in what seems like 100 years ago
06:56 AM jthornton: maybe if I get done with the machine I'm working on I'll build a mouse trap
06:57 AM XXCoder: cool :)
06:57 AM Jymmm: XXCoder: And your return is in 1918 dollars?
06:57 AM XXCoder: i got no idea what youre talking about
06:58 AM Jymmm: jthornton: Haven't people been doing that for like 1000 years?
06:58 AM Jymmm: XXCoder: The value of the dollar in 1918 (aka a 100 years ago)
07:00 AM Jymmm: XXCoder: https://www.dollartimes.com/inflation/inflation.php?amount=1&year=1918
07:04 AM sensille: if i use 3d adaptive clearing for roughening in fusion360, what is the finishing step? contour?
07:13 AM crazyben: Hello, did anyone had such an issue while starting up linuxcnc 2.8? https://pastebin.com/embed_js/YdiCCigM
07:13 AM jthornton: realtime error?
07:15 AM XXCoder: Jymmm: I know what inflation is. just unsure what youre talking about
07:15 AM MarcelineVQ: "I invested 100 years ago" "Are they going to pay you in 100 year old money?"
07:16 AM crazyben: jthornton, somtimes a realtime error commes up, sometimes I get the messages above. When it comes to a realtime error, the gui is almost completely frozen (respond times are extremely poor)
07:16 AM XXCoder: ahh 100 years was a throwaway joke. in reality I think i invested 3 years ago
07:16 AM XXCoder: Jymmm: sorry quite tired. about time to bed
07:17 AM jthornton: did you run the latency test for a long time?
07:18 AM jthornton: crazyben: I saw you PM
07:18 AM jthornton: 'd me a few times...
07:18 AM jthornton: not always in front of the PC's
07:19 AM crazyben: thornton: an PM? This was a mistake I think. This IRC Client is now to me - sorry
07:21 AM crazyben: jthornton: yes, I did. My Jitter times are 20700@Servo Thread 1ms and 25000@Base Thread 25us
07:23 AM XXCoder: whats you run while in jitter test?
07:25 AM crazyben: linuxcnc Latency-Test + 8 GLXGears + 4 "gzip -c /dev/urandom > /dev/null"
07:25 AM XXCoder: disk access added not bad
07:26 AM XXCoder: i usually do few glxgears and HD video
07:26 AM XXCoder: so your results is pretty firm
07:26 AM crazyben: I also added the following to grub: GRUB_CMDLINE_LINUX_DEFAULT="isolcpus=1,2 idle=poll intel_idle.max_cstate=0 processor.max_cstate=0"
07:26 AM sensille: disk access?
07:26 AM crazyben: the CPU is a coreI5
07:27 AM Jymmm: XXCoder: No worries, I was joking as well, goodnight =)
07:27 AM XXCoder: :)
07:27 AM XXCoder: gpu and such isnt my forte
07:29 AM crazyben: I also created yesterday an "latency-histogram --nobase --sbinsize 1000"
07:33 AM crazyben: The histogram was between -15 / +15 us and had a hight of 1E4
07:46 AM JT-Shop: I wonder what the height means...
07:46 AM * JT-Shop goes to clean chicken poop
07:46 AM crazyben: https://ibb.co/PQrRXXG
07:49 AM pcw_home: height is just the total samples per bin
07:49 AM pcw_home: (so increases as you run)
07:49 AM crazyben: ok, thank you.
08:08 AM jthornton: that makes sense
08:23 AM jthornton: lunch is done time to head to the industrial park and make money for a change
08:49 AM gregcnc: more than likely it's some power management thing killing the latency
08:50 AM gregcnc: I have a box that runs great, until the fan needs to turn on to full speed, then it's hit with a 500,000 or larger delay
08:52 AM jthornton: he left a long time ago...
09:02 AM pcw_home: Yeah he has his servo thread set to 10 KHz, that's not going to fly...
09:04 AM gregcnc: Wow 10k
09:06 AM rmu: 10k and ethnernet protocol
09:07 AM pcw_home: Yeah 10K will work with some systems and our PCI cards but not Ethernet/EtherCAT
09:08 AM pcw_home: 10K servo thread
09:09 AM gregcnc: oh, a few weeks ago someone stopped in running a mesa setup of some kind with 500,000 latency with no trouble, can't remember what he asked about though
09:10 AM pcw_home: as long as you meet the deadline, latency only has secondary effects
09:10 AM pcw_home: (with hardware step generation or encoder counting)
09:12 AM pcw_home: if you consider a hardware step/dir system, even a totally missed update cycle is a no-op if you are moving at a constant velocity
09:14 AM pcw_home: and only causes a minor error during acceleration (for low acceleration machines like mills/lathes)
09:51 AM Roguish_ is now known as Roguish
03:16 PM XXCoder: pcw_home: he said latency was 15k and set it to 10k? dang
03:16 PM XXCoder: my setup it is 15k and I set it to 25k to give plenty of room
03:25 PM pcw_mesa: No, he set the base thread to 100K (10 KHz) but base thread makes no sense with EtherCAT AFAIK
03:26 PM XXCoder: oh misunderstood. thanks
03:58 PM Deejay: gn8
07:00 PM ziper: I'm worried my belts are way too whimpy
07:44 PM andypugh: which belts?
07:44 PM andypugh: Mini lathe?
07:47 PM ziper: router table. GT2 6mm width
07:48 PM andypugh: I would imagine that some design effort went in to it.
07:49 PM andypugh: When the design is “guess” or “loks right” the errer is generally too big rather than too small.
07:50 PM ziper: uhh I can confirm that very little design effort went into it
07:50 PM andypugh: It’s not that hard to convert your motor torque in to a belt tension and see if it’s within spec.
07:51 PM andypugh: Is this your own design?
07:51 PM andypugh: (I came in late)
07:53 PM ziper: yes
07:53 PM andypugh: What is your motor torque?
07:57 PM ziper: 1.26 Nm
07:58 PM ziper: pulley diamter 16mm
08:01 PM andypugh: http://www.sdp-si.com/D265/PDF/D265T146.pdf
08:01 PM andypugh: After a quick glance, I think you are fine.
08:11 PM ziper: aye, but now I am worried the gantry will be too heavy
08:42 PM Tom_itx: what is this for?
08:46 PM Tom_itx is now known as Tom_L
11:29 PM ziper: Tom_L, foam cutting router table
