02:28 AM Deejay: moin
02:50 AM weenerdog: mwanyaya
02:53 AM XXCoder: ayaynawm
03:09 AM sensille: does this look ok to mount small workpieces vertically? https://www.sorotec.de/shop/Niederzugschraubstock-BG50.html
03:12 AM XXCoder: looks like its made to hold small parts and even rods
03:12 AM cpresser: yes, you might want to get some parallels together with that vise to set the vertical height
03:12 AM XXCoder: rods, vertically or horzionally
03:14 AM sensille: ah, because of those small notches
04:57 AM jthornton: morning
05:09 AM Tom_L: hello
05:17 AM -!- #linuxcnc mode set to +v by ChanServ
05:20 AM XXCoder: hey jthornton
05:20 AM XXCoder: sensille: yeah
05:20 AM XXCoder: i'd suggest make soft jaws with larger notches if need to mill a rofd
05:21 AM jthornton: hey XXCoder
06:34 AM XXCoder: pretty nice sin/cos tutorial, from machinist side https://www.youtube.com/watch?v=PO-Ab7YfBzY
06:35 AM XXCoder: im watching as funny jokes than learning as maths pretty easy to me
06:39 AM jthornton: hmm cc is not working for me :(
06:40 AM XXCoder: this old tony cc? its autocaptions you have to turn it on in settings if you meant that videp
06:43 AM jthornton: odd, never had to do that before
06:44 AM XXCoder: regular captions button show by default but not for autocaptions
06:44 AM XXCoder: nowdays autocaptions is quite good. I still remember few years ago lol
06:45 AM jthornton: prob something I set in the old pc but forgot... like I said a million things to get setup with a new pc
06:45 AM XXCoder: yeah fresh install "smell" lol
07:09 AM * miss0r feels like bragging:
07:10 AM miss0r: After 10 years in the works, I now have license plates on my 1972 8(" series three landrover. :)
07:10 AM miss0r: 88"*
07:10 AM jthornton: cool got a photo of it?
07:11 AM miss0r: yeah. hang on
07:16 AM miss0r: https://imgur.com/a/9isbfID
07:17 AM miss0r: paintjob will wait till this summer, when the weather is nice again ;)
07:17 AM miss0r: I uploaded two photos; so you can also see that it looks good underneath :)
07:17 AM jthornton: I was wondering for a second what the thing on the hood was then I remembered they put the spare tire there
07:18 AM jthornton: geez looks brand new underneath
07:18 AM miss0r: I welded that fram up from scratch ;)
07:19 AM miss0r: I started with a flat sheet of steel and just cut'n welded from there ;)
07:19 AM jthornton: old frame rusted out?
07:19 AM miss0r: yeah.. It was gone
07:19 AM miss0r: hmm.. I have an album on photobucket with a picture of the old frame, hang on
07:21 AM miss0r: if you go to this link and just press the arrow in the left of the picture, theres alot of photos of the old frame & the new buildup: http://s820.photobucket.com/user/Garfield87/media/IMG_0089.jpg.html
07:23 AM miss0r: When you see the photos, you will realize that "old frame rusted out" is quite the understatement :)
07:24 AM rmu: "grinder and paint make you the welder you ain't"
07:25 AM jthornton: hmm only the one photo of it sitting on the lorry
07:26 AM miss0r: you can't navigate?
07:26 AM jthornton: only to the right and that is something else
07:26 AM miss0r: huh...
07:26 AM miss0r: gimmi' a sec
07:26 AM rmu: this http://s820.photobucket.com/user/Garfield87/library/?sort=3&page=1 works better
07:27 AM miss0r: Yeah, indeed. Just go to the last page and roll backwards
07:27 AM miss0r: That album/profile there was created for the land rover project
07:28 AM XXCoder: miss0r: outer looks ok. under is amazing
07:28 AM rmu: that was some serious reconstruction... i hope you can enjoy it for a long time
07:28 AM miss0r: although, some other stuff has found its way in there. but nothing I am too ashamed of :)
07:28 AM miss0r: XXCoder: yeah. The outside paintjob will wait for this summer :) I don't want to be freezing while I am doing it :)
07:28 AM miss0r: rmu: Thanks. I hope so too
07:29 AM miss0r: rmu: I started this project in 2010. Worked on it for two years & life got in the way.
07:29 AM * rmu probably watched too many of those "stupid drivers". i would be heartbroken if somebody ruined my self-rebuilt car, esp. after 10 years of work
07:29 AM miss0r: I started back up around 4 or 5 months ago, and completed the job
07:30 AM XXCoder: just dont drive in russia... and washington state
07:31 AM miss0r: XXCoder: With this type car other drivers should mind me as well... THEIR car is MY crumble zone :D
07:31 AM rmu: i guess it happens everywhere
07:31 AM XXCoder: lol
07:31 AM miss0r: the front bumper is steel bolted directly to the steel frame.. :)
07:31 AM miss0r: the rear "bumber" IS the steel frame
07:31 AM rmu: how much wire did you use?
07:32 AM miss0r: rmu: around 15kgs
07:32 AM miss0r: (if I recall correctly)
07:32 AM miss0r: Not as much as I feared ;)
07:34 AM rmu: i would have guessed 2-3 times that amount... but i'm no welder
07:40 AM miss0r: I might very well be remembering wrong; it is 7ish years ago I did the welding :) and I am no welder either
07:40 AM miss0r: well.. apart from having done alot of welding - Not a welder by trade, that is
08:02 AM gregcnc: looks like more rust than rover?
08:03 AM XXCoder: thats amazing. a traveling collection of rust
08:03 AM miss0r: gregcnc: yeah.. :D
08:03 AM miss0r: it is... SO MUCH rust on the shop floor while taking it apart
08:04 AM gregcnc: did you essentially build a new chassis?
08:05 AM miss0r: I did. You can see the process on the link rmu pasted
08:05 AM gregcnc: yes, just confiriming
08:05 AM JT-Shop: game camera confirms I'm feeding the feral cat which I want to hang around and not a coon or opossum
08:06 AM miss0r: jt-shop: You want the cat to hang around to kill off pests?
08:06 AM XXCoder: opossum is great on eating ticks
08:07 AM JT-Shop: miss0r: yes, we have wood rats (big ones) and mice
08:07 AM JT-Shop: wood rats love to eat trucks and cars wiring
08:08 AM miss0r: hehe. I live next to a farm where they have 15-20 feral cats they feed.. NO RATS around here :D
08:08 AM JT-Shop: so are guineas but I don't want either one
08:08 AM JT-Shop: that's what I'm hoping for so I can get my truck out of the shop... it takes up way too much room lol
08:09 AM miss0r: :S You need to get rid of ticks to get the car out? :D
08:35 AM jthornton: hoping the feral cat kills all the rats and mice so I can get my truck out...
08:37 AM jesseg: you know an alternative to feral cats is weasles. They are the cutest little thing every. They are rather like super tiny cats with a self-image larger than the average housecat. They will catch a rat their own size and eat it.
08:38 AM jthornton: wow Monique laid a 75 gram egg...
08:38 AM jthornton: problem with weasels is they like to eat chicken blood too... so I have a few traps out for them as well
08:39 AM jesseg: jthornton, I once had a chicken that was super silly. Not bright at all. But she gave us nice olive drab green eggs. But one day she knew the egg was ready but she put off going to the nest box till a little too late. When she decided to head that way, she walked over and jumped up into the nest box which was about 2 feet up off the ground.
08:40 AM jesseg: Problem is the egg popped out mid air while she was in flight up to the nest box. No problem, though, she got all cozy in the next box then started cackling about her newly laid egg.
08:40 AM jesseg: but it was on the floor
09:15 AM jthornton: my neighbor had one lay an egg on the ramp and it was balanced on a cleat lol
09:29 AM flyback: bmc
11:10 AM Wolf__: miss0r: I think ya have my planned early bronco restoration beat with the amount of work in that rover lol and be glad you dont have to worry about hitting on of the trucks I built bumpers for https://i.imgur.com/PKS1kDE.jpg 12.5mm or 19mm steel plate + 4.8mm or 6.35mm tube for the tail lights depending on application
11:37 AM PL7icnc: Someone here on Mesa Firmware Modification
11:41 AM rmu: PL7icnc: just ask, in time somebody will read it and get back to you
11:42 AM PL7icnc: i got a 7i92m running but i dont like the way ir workes on the given bitfiles
11:42 AM PL7icnc: Question Can i as a Newbe make mye own bitfile
11:43 AM PL7icnc: All documentations are on older Pci FPGA
11:43 AM PL7icnc: and the Software Used is no longer available
11:43 AM rmu: PL7icnc: http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php
11:43 AM pcw_home: what software?
11:44 AM PL7icnc: the xlink
11:44 AM pcw_home: all older version of webpack are available from Xilinx
11:44 AM PL7icnc: will this make also bitfiles for the 7i92
11:45 AM pcw_home: I use 14.7 on Linux, works fine (you need 9.X for the older Spartan II stuff)
11:46 AM PL7icnc: ok will this run on the uspace kernal of debian 9
11:46 AM pcw_home: its kernel agnostic
11:47 AM rmu: PL7icnc: perhaps you should state your real problem, without any FPGA experience rolling you own bitfiles probably won't get you very far
11:49 AM PL7icnc: rmu, yiu may be right as pcw also mailed me
11:49 AM PL7icnc: its a hell of terning all signals by relais
11:50 AM PL7icnc: also on power up all drivers get waeard as no control is on
11:50 AM PL7icnc: 7i92 needs power bevor Linuxcnc gets started
11:50 AM PL7icnc: the Parport behaves the Other way
11:51 AM PL7icnc: First Linuxcnc then Power mashine
11:51 AM PL7icnc: This makes a Full refit of the Cabinett
11:52 AM PL7icnc: Second main logic power units
11:52 AM pcw_home: This is not fixable in firmware (and parallel port do not have defied states at power up)
11:52 AM PL7icnc: 2 Maionswitches
11:52 AM PL7icnc: pcw_home, they do not need them as the Controll is running bevor the mashine
11:53 AM rmu: PL7icnc: wire machine-power or servo enable through a relais
11:53 AM pcw_home: yes Estop circuitry should disable everything before startup
11:54 AM PL7icnc: i got time so i will try to interfear the bitfile
11:54 AM rmu: PL7icnc: you should also consider the case that power-loss or arbitrary components of your machine should not lead to unsafe or runaway conditions
11:55 AM pcw_home: This cannot be fixed in the firmware
11:56 AM PL7icnc: But i can get the stepgens to my way
11:56 AM pcw_home: yes if you renumber the stepgens so you dont have any on pins you wish to be GPIO
11:57 AM pcw_home: or just use GPIO on the second connector
11:57 AM PL7icnc: IS THIS A MORE EASY TASK
11:57 AM PL7icnc: the second connector is in a second cabinett
11:58 AM PL7icnc: its a 2 mashine one frame setup
11:58 AM * Loetmichel sometimes ask himself in which imaginary world his boss lives... he has invited the customer to do technical acceptance for 24 PCs tomorrow... of which we have ONE 90% done. 5 PCs have 70% of the parts milled already, the remaining 18 still have 70% of the parts to be manufactured on the CNC mill... Not to mention any assembling of the PCs... sometimes my boss acts a bit like trump...
11:58 AM * Loetmichel :-(
11:58 AM PL7icnc: so i like to switch mashines in one G-code
11:59 AM PL7icnc: worked sall on parport
11:59 AM pcw_home: Most serious breakouts have a chargepump so that the BIOS/OS port probe at startup does not randomly twiddle I/O bits
11:59 AM PL7icnc: i will get throu this
12:00 PM PL7icnc: pcw_home, not needed as PC and LinuxCnc is running bevor the Main mashine switch
12:01 PM pcw_home: If that's the case, the initial 7I92 I/O states don't matter
12:02 PM PL7icnc: no the 7i92 needs to be powerd bevor the Linuxcnc runs
12:02 PM PL7icnc: so all pins are High all Relais are on
12:02 PM pcw_home: Thats fine, you said the machine was not enabled at this point
12:03 PM pcw_home: relay state should be a no-op in Estop
12:03 PM PL7icnc: e-stop shuts down logic power as all relais are 5V
12:04 PM PL7icnc: i will solve the srtepgen numbering first
12:04 PM PL7icnc: and free pins 89 16 17
12:05 PM PL7icnc: let me by a new Harddrive and start on
12:05 PM crazyben: sorry, but can someone tell me what kind of kernel (rt? rtai?)I have? 4.9.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
12:05 PM PL7icnc: https://www.youtube.com/watch?v=meO-b6Ib17Y
12:06 PM PL7icnc: crazyben, this is the right one debian stretch Uspace
12:06 PM PL7icnc: pcw_home, this video gives me the start
12:07 PM crazyben: PL7icnc, thank you - I am still having trouble with it and ethercat
12:09 PM PL7icnc: crazyben, i did strugle with the mesa hm_eth but it workes gret now
12:09 PM rmu: crazyben: did you try adding the missing header file?
12:12 PM crazyben: rmu, not yet. I I found something within dmesg that confuses me
12:12 PM crazyben: rmu, these are the messages: [ 827.082545] perf: interrupt took too long (2512 > 2500), lowering kernel.perf_event_max_sample_rate to 79500 [ 1077.783308] NOHZ: local_softirq_pending 80
12:13 PM rmu: crazyben: report back when you did
12:14 PM pcw_home: crazyben: that's harmless AFAIK
12:15 PM rmu: in linuxcnc-ethercat file src/lcec_main.c, can you add #include "rtapi_mutex.h" after #include "rtapi_app.h" and rebuild lcec?
12:15 PM rmu: crazyben: in linuxcnc-ethercat file src/lcec_main.c, can you add #include "rtapi_mutex.h" after #include "rtapi_app.h" and rebuild lcec?
12:16 PM rmu: it seems the header file is not included so the C compiler uses some inferred definition of rtapi_mutex_get instead of the inline impl, causing the missing symbol error when loading lcec.so
12:26 PM crazyben: rmu, looks a bit better. I dont have connection to the machine yet as I have to clean and reinstall ethercat
01:16 PM Papagno: Hi at all. On actual master have a problem with spindle at speed pin. If command m3 s10000 and abort first the receive signal spindle at speed = true and affter command g1 z-10 f100 , the g1 not is executed remain append and cnc in run . the axis wait spindle at speed, but i first have abort .this is test on actual master. the same problem is with M5 first the receive spindle at speed = true
02:51 PM SpeedEvil is now known as Guest29425
03:42 PM jelly-home is now known as jelly
04:02 PM Deejay: gn8
05:02 PM jthornton: yea I got to work today and tomorrow too
05:36 PM Roguish: hey, anyone work for Generous Motors?
05:43 PM Roguish: looks like they're not sooooo Generous any more.....
05:45 PM andypugh: Hmm?
05:46 PM Roguish: shutting 5 factories.
05:48 PM andypugh: Yes, I think all the car manufacturers are looking to reduce capacity. I think there is a feeling we have passed “peak car”
05:48 PM andypugh: Which in some ways is a good thing. Unless you work at a car plant.
05:49 PM andypugh: Guess where I work....
06:41 PM Tom_L: andypugh, for now at least :(
06:42 PM andypugh: It feels like tome for a change anyway.
06:42 PM andypugh: 10 years in the same job? (Yawn)
06:42 PM Tom_L: what industry would you like to try?
06:43 PM Tom_L: spacex maybe...
06:44 PM andypugh: I did apply for a job developing delivery drones for Amazon
06:45 PM andypugh: (As a caver I am not sure I want to be anywhere near Musk)
06:48 PM Contract_Pilot: Sup.
06:49 PM andypugh: Hai
09:34 PM Roguish: andypugh: Tesla is just a few miles from me. and I have stock in 'em.
09:42 PM Roguish: Musk is a bit of a loose cannon. But he's working it hard. Tesla is way out front of all the other electric cars. All the way around.
10:07 PM Samiam1999: Amazon, Walmart and several other drones are all based on ROS fyi
10:11 PM Samiam1999: Newest version of ROS 2 "Crystal Cleemys" comes out in a couple of weeks incase your interested https://index.ros.org/doc/ros2/
10:22 PM BitEvil is now known as SpeedEvil
