01:01 AM tiwake: Square-D came and did a variable frequency drive presentation for 2 hours
01:03 AM tiwake: there were a lot of IoT things on it :-/
01:23 AM t12: lol
01:23 AM t12: internet of drives
01:27 AM archivist: Interned of Disasters
01:30 AM tiwake: t12: they talked about some sort of security certificate they got from... I don't remember where
01:31 AM t12: cissps around every corner
01:32 AM IchGucksLive: Morning from Germany
01:32 AM tiwake: I asked who did their TCP-IP stack programming
01:33 AM tiwake: if it was developed all in-house, if they adopted some sort of third party software suit for that stuff
01:33 AM tiwake: the guy didn't know, of course
01:40 AM IchGucksLive: moring CaptHindsight
01:40 AM IchGucksLive: im off to the Kindergarden with Grandchild
02:26 AM Deejay: moin
03:07 AM wicki_: hi all...
03:33 AM wicki_: is there a working version of check_config.tcl (conversion of ini-files from axis to joins) anywhere?
03:34 AM Mibka_: fuck.. Ordered a 60W Laser cutter/engraver from amazon.de yesterday and now the seller tells me the item is fake, his account was hacked and I'll have to wait for amazon to pay back...damn :-(
03:42 AM wicki_: is even anybody here using 2.8.xxx ?
03:43 AM archivist_herron: I am not
03:44 AM archivist_herron: there will be later when the USA wakes up
03:51 AM Longbow: hello! Why would LinuxCNC start the program/motion even if one axis will not move? - I intentionally disabled one axis to see if it would move and it will! What happens if one servoModule is at fould!?
03:51 AM Longbow: at *fault
03:54 AM Longbow: If it happens during milling it will collide...
04:13 AM archivist_herron: you wire a fault pin back into linuxcnc to halt it
04:13 AM archivist_herron: add as much protection as you want
04:14 AM archivist_herron: some faults will be detected on servo systems with the encoder feedback,
04:14 AM archivist_herron: here ferror is the limit
04:15 AM archivist_herron: a blunt cutter holding any axis back will trip that
04:20 AM wicki_: so I have tried to start linuxcnc 2.8.0_pre serveral times with several configs (the example-configs frim the package too): not even one will work. error is everatime the same:
04:20 AM wicki_: check_config: ERROR
04:20 AM wicki_: Missing [KINS]KINEMATICS=
04:20 AM wicki_: Missing [KINS]JOINTS=
04:53 AM Longbow: OK, if I make the ferror smaller in the .ini file it should halt on its own?
04:59 AM Longbow: yes, it works now. I forgot and leaved a large margin of ferror and min_ferror. Now it stops. Thanks!
05:13 AM XXCoder: hey JT-Shop you in?
05:13 AM XXCoder: or maybe jthornton
05:14 AM XXCoder: hey gotta
05:14 AM XXCoder: he should be in in a hour or so
05:15 AM XXCoder: usually says hello heh
05:18 AM neothefox_: hi again
05:18 AM XXCoder: hi for first time
05:20 AM neothefox_: XXCoder, neothefox is my PCs nickname, and since I left it open I am stuck with underscore on my laptop
05:20 AM XXCoder: heh i wasnt here for over 10 hours
05:20 AM neothefox_: oh, ok
05:20 AM XXCoder: I dont even see any of you previous entry and converations :)
05:22 AM neothefox_: I've been struggling with RTAI kernel on one specific CPU
05:50 AM jthornton: morning
05:50 AM XXCoder: hey jt
05:51 AM XXCoder: guy here has same model printer as us
05:51 AM XXCoder: he wanna see your x assembly upgrades
05:51 AM jthornton: who is that?
05:51 AM XXCoder: mind link pic? heh
05:51 AM XXCoder: gotta
05:51 AM jthornton: http://gnipsel.com/images/prusa-i3-clone/
05:52 AM XXCoder: gottaname|wurk:
05:52 AM XXCoder: oh yeah forgot you did y upgrade also lol
05:53 AM XXCoder: hmm your touch probe is simpler than i thought
06:17 AM jthornton: my touch probe?
06:17 AM XXCoder: yeah
06:17 AM XXCoder: was browsing other dirs heh
06:18 AM jthornton: ah my plasma
06:19 AM XXCoder: oh it was for plasma cool
06:19 AM XXCoder: I am still pondering how to do very flat probe
06:20 AM jthornton: http://gnipsel.com/images/plasma/touch-off-switch.jpg
06:20 AM jthornton: that one?
06:21 AM XXCoder: no
06:21 AM XXCoder: http://gnipsel.com/images/touch-probe/
06:22 AM jthornton: oh that is for the bp mill
06:22 AM XXCoder: bench press mill?
06:22 AM jthornton: bridgeport
06:23 AM XXCoder: heh was kidding
06:23 AM XXCoder: cool though
06:23 AM XXCoder: what is its repeatbility?
06:24 AM jthornton: it's as good as the BP is lol, the ball things were not pressed in all the way so I could not center it at first till I took it apart and pressed them in
07:15 AM wicki_: re.. I got ver. 2.8 running now. an here is my problem again: my X-axis moves in/out and ist also able to rotate. because of the mechanical construction, in/out of X-axis is a pain movement - but when is rotating, it also moves in/out (depending from rotation-direction). so I must correct the in/out-position while rotating. any hint, where to put this correction?
07:16 AM wicki_: ("plain" not "pain" movement) ;-)
07:17 AM wicki_: is a kinematic-file the right solution?
07:18 AM Loetmichel: *muhaha* Co-worker just came out of the workshop: "Blyat, that was the last engraving D-bit" $me: "just gimme the dremel with the diamond cutoff disc, a broken TC mill bit and a few minutes..." *grind away freehand... "here is xuour new d-Bit" ... his face was priceless ;)
07:19 AM Loetmichel: *muhaha* Co-worker just came out of the workshop: "Blyat, that was the last engraving D-bit" $me: "just gimme the dremel with the diamond cutoff disc, a broken TC mill bit and a few minutes..." *grind away freehand... "here is your new d-Bit" ... his face was priceless ;)
07:19 AM Loetmichel: sorry
08:59 AM wicki_: *grmbl* what is linuxcnc trient to say? Starting LinuxCNC...
08:59 AM wicki_: check_config: Unknown [KINS]KINEMATICS=corexykins
08:59 AM wicki_: corexykins is loaded:
08:59 AM wicki_: corexykins 12495 1 motmod
08:59 AM wicki_: hal_lib 40072 5 hal_parport,stepgen,motmod,pwmgen,corexykins
09:20 AM dgarr: wicki_: it is just a message that check_config doesn't know how validate that particular kins module, it is not an error
09:32 AM wicki_: dgarr: ok - thx. but corexy does not work as expected..... it looks like as it is doing nothing....
09:33 AM DrippityDrops: Loetmichel: thats the difference between us and them :P
09:36 AM Loetmichel: who is "them"?
09:36 AM DrippityDrops: I was at a factory not long ago and a guy busted his tap off in a hole, I heard it and looked over you could see him starting to lose it. I walked over with a punch and hammer and started backing the remainder of the tap out. Realizing he didnt have to completely redo his whole part was super excited.
09:37 AM Loetmichel: hrhr
09:37 AM DrippityDrops: People that know how to make do with a situation and people who dont =D
09:38 AM Loetmichel: "you are only a real home machinist if you catch yourself making a fixture to make a tool to drill a contraption you made to kold a workpiece whose orginal pourpose is long forgotten in history" ... as m y first apprenticeship master tended to say ;)
09:38 AM DrippityDrops: being able to walk over to the pedestal grinder and regrind a drill bit also gets peoples attention. I didnt realize that wasnt common practice anymore
09:39 AM DrippityDrops: Loetmichel: =D
09:39 AM Loetmichel: -k+h
09:40 AM DrippityDrops: I dont use a drill gauge usually. Just grind then find a good corner on the wheel and split the webbing
09:40 AM Loetmichel: yes
09:40 AM Loetmichel: i can do that freehad down to 1.5mm
09:40 AM Loetmichel: 1mm drill bits tend to drill 1.2mm holes when i grind them without a gauge tho
09:41 AM SpeedEvil: Loetmichel: that can be a plus :)
09:41 AM DrippityDrops: nice, if im lucky that day and I havent had too much coffee I can get gring a 1/16 but I dont really look at the drill just kinda feel for the right motions grind, rotate grind. Then try to look
09:41 AM DrippityDrops: splitting those can be really tough tho
09:42 AM Loetmichel: i usually do the small ones on a dremel with a cutting disk
09:42 AM DrippityDrops: I'll have to look into that one
09:42 AM Loetmichel: ... or two disks usually ;)
09:43 AM Loetmichel: needs a steady hand though
09:43 AM DrippityDrops: my my problematic ones are small carbide
09:43 AM Loetmichel: the smallest carbide drills i own are .3mm
09:44 AM DrippityDrops: I can always get the angles and relief right but have no good way to split them
09:44 AM Loetmichel: (about 1/100th inch)
09:44 AM DrippityDrops: mostly due to lack of proper wheels I suppose
09:44 AM Loetmichel: i have no way to grind them
09:44 AM DrippityDrops: .3mm
09:44 AM Loetmichel: they already break off when you sneeze too loud
09:44 AM DrippityDrops: nah you would be as likely to bust them in a way that can cut
09:45 AM DrippityDrops: I never used a drill doctor before
09:45 AM DrippityDrops: I just assumed they were junk
09:45 AM SpeedEvil: They do a reasonable job
09:45 AM Loetmichel: what i heard: they are junk
09:45 AM SpeedEvil: Do they do an optimal job - no
09:46 AM DrippityDrops: we should build a mini cnc drill, tap and mill grinder for the linuxcnc community. atleast we know MOST people could use one =D
09:47 AM SpeedEvil: A 50mm*50mm*50mm workspace 5 axis mill/grinder would be so handy for that
09:48 AM SpeedEvil: Clamp it on the end of a bar, and it forms the appropriate cutting tool.
09:48 AM * Loetmichel just used his new 3dprinter today foer the first time to make something useful: a 6 pack of file handles for the mini file set
09:49 AM SpeedEvil: :)
10:04 AM Loetmichel: the Printer did a pretty decent job, sturdy as hell and didnt even need to use the set screws, the knurling on the shsfts is enough to hold the files when the handles are hammered in: http://www.cyrom.org/palbum/main.php?g2_itemId=16548&g2_imageViewsIndex=1
10:30 AM wicki_: oki... corexykins is working now. maybe, I can use ist as a startingpoint. what I need is: if X-axis moves 2 steps in direction "+", Y-axis has to move 1 step in direction "-"
10:34 AM wicki_: I think, I must store X-pos at every rtapi-loop and compare it with the last position. if it differs, move the Y-axis. but doesn't this result in a "joint-following-error" ?
10:46 AM cradek: are you using http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/emc/kinematics/corexykins.c;h=6d888c5a19e0fdcc6ea72d8b098417bf3225db16;hb=c0778d66cf0fc2d57fa572345765f1fd8d0d6927
10:49 AM wicki_: cradek: yes, I think so... "
10:49 AM wicki_: 400 - Invalid hash parameter "
10:49 AM archivist: or link axes with some hal
10:49 AM wicki_: its the last 2.8.0 pre from github
10:50 AM cradek: are you having a problem with the corexy kinematics?
10:50 AM wicki_: archivist: do you have an example?
10:50 AM cradek: or are you adapting for a different machine configuration? I don't understand what problem you are trying to solve
10:51 AM archivist: wicki_, hobbing on the wiki is an example of that
10:52 AM archivist: as is torch height and skunk and his thermal error correction
10:52 AM archivist: many ways to do things, what is the machine
10:53 AM wicki_: cradek: no the problem is: X and Y are mechanical connected: its the same axis. if X rotates, it moves also in Y-direction
10:53 AM cradek: then they aren't X and Y
10:54 AM cradek: they are joints
10:54 AM wicki_: yes
10:54 AM cradek: kinematics translates to and from XY from joints
10:56 AM wicki_: here is a picture of it: https://forum.linuxcnc.org/media/kunena/attachments/21794/cerec_mod_2017-04-10-3.jpg
10:57 AM cradek: that's not corexy at all
10:58 AM cradek: that looks like a XZA machine to me
10:58 AM wicki_: of course. corexy its just a starting point
10:58 AM cradek: X is a linear axis, you are mistaken to say X rotates
10:59 AM wicki_: yes, in this pic its defined as X - but if X or Y - the problem is the same:
11:00 AM wicki_: rotating this axis results also in an in/out move
11:00 AM archivist: rotating axes are by convention A,B,C
11:00 AM cradek: it also moves in/out?
11:01 AM wicki_: yep
11:01 AM cradek: oh I misunderstood in/out. you mean toward/away from viewer?
11:01 AM cradek: I understood it as left/right on the picture
11:02 AM cradek: still not sure which motions you have
11:02 AM wicki_: in ths picture, it can move to left and to right
11:02 AM archivist: I think it as left right in the image
11:02 AM cradek: ok that is X
11:03 AM cradek: does something move in Y? toward/away from camera?
11:04 AM wicki_: no - the axis named "X" is able to rotate.
11:05 AM cradek: X is a linear direction, A is a rotation around X
11:05 AM wicki_: but any rotation causes a movement to left or right
11:05 AM DrippityDrops: cradek: I just talked to farmer guy, they want me to help them design an automatic egg washing system for small free range chicken coops =D
11:06 AM wicki_: sehr lustisch....
11:06 AM archivist: wicki_, in that image you dont seem to have a Y
11:06 AM cradek: DrippityDrops: neat! chickens are cool.
11:07 AM wicki_: the problem is the same - regardless of the axis-names...
11:07 AM archivist: I have repaired an egg washer
11:07 AM archivist: wicki_, you can gear them together in gcode, hal or kins
11:07 AM cradek: I don't understand the problem still, and confusion about axis names is contributing to that
11:08 AM archivist: I am guessing this is actually on a nut so no real gearing needed
11:09 AM DrippityDrops: wicki_: value of joint0 and joint1 = X? and ALSO value of joint0 and joint1 = Y?
11:09 AM wicki_: in g-code.... hmmmm... I never thought about that....
11:10 AM archivist: I cut helicals that way
11:11 AM DrippityDrops: wicki_: so that disk is X? would it be more fitting to call "X" a spindle?
11:12 AM cradek: archivist: do you understand how the machine moves?
11:13 AM archivist: cradek, not yet
11:13 AM wicki_: DrippityDrops: no - the in/out movement is "standalone" possible. but if this axis rotates it causes a movement from left to right (in and out)
11:13 AM archivist: missing info
11:13 AM wicki_: I can make a video... :-)
11:13 AM archivist: so you want independent and linked?
11:14 AM cradek: a video might help
11:14 AM archivist: I would be using G1 F.05 x-.063 Y[0-#20] Z[0-#5] A[0-#<rotation_angle>] (rotate blank 7 turns) as an example for linked
11:14 AM DrippityDrops: ok, but why does it cause a rotary motion due to a linear movement? is this due to mechanical or just software? yeah actually video and location of motors/actuators would be very helpful
11:15 AM archivist: or use inverse time mode for the speed
11:15 AM wicki_: just a moment....
11:16 AM DrippityDrops: hopefully his issue is purely kinematics and axis definitions
11:19 AM wicki_: fuck... (cheese:8329): WARNING **: Device '/dev/video0' is busy
11:20 AM DrippityDrops: just remove the panels and click a picture? =D
11:34 AM robi: oops left the cnc hot all night
11:35 AM robi: x stepper is 71F and Z is 66F and frame is 55F
11:35 AM robi: NICE!!!!
11:35 AM DrippityDrops: robi: no, you were simply testing the ability to run a lights out operation!
11:35 AM robi: .nick Crom
11:35 AM robi is now known as Crom
11:36 AM DrippityDrops: and you forgot to change your nick, rough morning!
11:36 AM DrippityDrops: =D
11:36 AM Crom: just got up... 0906 so 0902 I got up...
11:37 AM DrippityDrops: this tells me you check on your cnc machines before brushing your teeth :P
11:37 AM Crom: come out back for my morning Ciggi Butt
11:37 AM DrippityDrops: ooh good idea, I coulod go for one
11:38 AM Crom: while my tea is steeping
11:38 AM Crom: ;)----~~~~
11:38 AM DrippityDrops: yeah, im about starting coffee, have a smoke, come inside, get coffee have a cup, then brush
11:38 AM Crom: yep
11:39 AM DrippityDrops: )____)_______@~~~~~~~~
11:39 AM DrippityDrops: =D
11:39 AM DrippityDrops: oh I guess my parenth were backwards
11:40 AM Crom: oh those T6 AL disks are 40mm thick
11:42 AM Crom: stock pindle mount is 51mm thick
11:43 AM Crom: spindle
11:47 AM Crom: I have enough material I can make 2 mounts or 4 mounts which you bolt too
11:55 AM DrippityDrops: "11:45:44 AM - wicki_: just a moment...." LIES LIES I TELL YOU
11:55 AM DrippityDrops: :P gtg to the shop good luck with you kins wicki
12:17 PM Cromaglious_: Looking at these mt3 comes in a 3/4" collet. http://m.ebay.com/sch/i.html?_from=R40&_trksid=m4084.l1313&_nkw=Power+head+spindle
12:19 PM Cromaglious_: TTS in MT3? I see a 8000rpm mt3
12:23 PM gregcnc: why not just get the BT 30?
12:26 PM Cromaglious_: TTS is smaller and easier to do a tool changer
12:28 PM Cromaglious_: Hmm can a mt3 be reground to a R8???
12:28 PM Cromaglious_: Bbiab looking
12:29 PM IchGucksLive: hi from Germany
12:30 PM neothefox: https://pwnfox.duckdns.org/nextcloud/index.php/s/1UtBViO66dYozSm
12:30 PM neothefox: Here is the thin client I am working with
12:30 PM IchGucksLive: neothefox: did you solv the kernal problem
12:30 PM neothefox: IchGucksLive, Not yet
12:31 PM IchGucksLive: so let me help
12:31 PM IchGucksLive: what doe uname -a telöl you
12:31 PM neothefox: IchGucksLive, nice, thanks! I've brought one home today
12:32 PM neothefox: IchGucksLive, on stock debian kernel? or on RTAI one?
12:32 PM {HD}: My ballscrews and bearings are here!!!
12:33 PM neothefox: {HD} Congrats!
12:33 PM IchGucksLive: please post the output of uname -a
12:33 PM neothefox: IchGucksLive, Ok, give me a moment
12:33 PM neothefox: I'll hook it up
12:34 PM wicki_: re
12:35 PM Cromaglious_: MT3 can be recut to r8
12:37 PM IchGucksLive: wicki_: why are you on 2.8
12:37 PM IchGucksLive: it is the most front end
12:37 PM IchGucksLive: wicki_: use a stable version
12:38 PM wicki_: IchGucksLive: just for testing.... the others are 2.7
12:38 PM IchGucksLive: so there are fudamentic changes going on and you ask on the support channel to them
12:38 PM Cromaglious_: I'm running 2.8.0 for gmoccapy
12:40 PM IchGucksLive: wicki_: so you got aready expiriences on LCNC
12:44 PM wicki_: my last 2.8-test is one year ago, I think. and I thought, it schould be al little bit more stable now....
12:44 PM {HD}: Well, they send the wrong couplings! Everything else looks ok.
12:45 PM IchGucksLive: {HD}: high precision onter easter eve
12:45 PM IchGucksLive: carving bunnys
12:46 PM neothefox: IchGucksLive, fuck my luck, I've grabbed a broken one
12:46 PM neothefox: Or maybe it's GPU wouldn't see my display
12:46 PM neothefox: Looks like untill tomorrow I can't work with it
12:46 PM {HD}: IchGucksLive: Huh?
12:47 PM IchGucksLive: the ballscrews
12:47 PM IchGucksLive: neothefox: no matter you will get it
12:47 PM Cromaglious_: Running pre1 build 2095 i think
12:48 PM neothefox: IchGucksLive, thanks! I'll try again tomorrow
12:48 PM IchGucksLive: neothefox: dpkg -l linux-image* | grep ii
12:48 PM IchGucksLive: to see what kernals the system has
12:49 PM neothefox: Ok, will do
12:49 PM Cromaglious_: There is some newer builds...
12:50 PM Cromaglious_: Wooo nice touchscreen. http://www.frys.com/product/8272576?site=sr:SEARCH:MAIN_RSLT_PG
12:57 PM {HD}: HAIL!
12:57 PM IchGucksLive: neothefox: still on
12:57 PM neothefox: IchGucksLive, yup
12:58 PM IchGucksLive: neothefox: here at 1min it showes how the kernel shoudt tell at uname WHEEZY https://www.youtube.com/watch?v=Ox0s1rFGAH8
12:58 PM IchGucksLive: its the gampad install advice
12:59 PM neothefox: IchGucksLive, Yeah, this one don't boot
12:59 PM neothefox: but that's because it's PAE
12:59 PM neothefox: VIA Eden can't do it, so it just reboots
01:00 PM neothefox: then I've installed 486 kernel, also RTAI, and it hangs right after GRUB
01:00 PM IchGucksLive: you may hafe to force NOAPIV
01:00 PM IchGucksLive: NOAPIc
01:00 PM IchGucksLive: thy at grub
01:00 PM IchGucksLive: go into the command by pressing e
01:01 PM neothefox: Ok, I'll write it down
01:01 PM IchGucksLive: then edit the grub kernal start line SPLASH quiat
01:01 PM IchGucksLive: tad ther nolapic
01:01 PM IchGucksLive: and press F10
01:01 PM IchGucksLive: or X on Debian
01:03 PM IchGucksLive: let me see im starting up a debian on a think pad
01:05 PM IchGucksLive: neothefox: here its the oposit
01:05 PM IchGucksLive: lapic quiet
01:05 PM IchGucksLive: F10 is wright
01:06 PM neothefox: Ok, I'll try this tomorrow
01:07 PM neothefox: I also wanted to compare .config from debian kernle and linuxcnc kernel
01:08 PM IchGucksLive: ok do you know what imean with the lapic at grub start or shoudt i post more
01:08 PM neothefox: IchGucksLive, yeah, I am familiar with Linux
01:09 PM neothefox: perfectly clear, thanks
01:09 PM IchGucksLive: NP ;-)
01:09 PM neothefox: :)
01:22 PM Cromaglious_: Neothefox you have it booting on the stock kernel correct?
01:23 PM Cromaglious_: In /boot there should be the .config of that kernel
01:24 PM {HD}: I am going to go do this. https://www.youtube.com/watch?v=1NF8EFoPlrk
01:26 PM Cromaglious_: I took that from my 3.16.9 kernel dropped it in the kernel src dir then ran make nmenu. There is also a utiliity that will preload the modules nessary to boot into the initial ram disk image
01:26 PM neothefox: Cromaglious_, yup, it does boot with stock Wheezy kernel
01:26 PM Cromaglious_: I'll be home in 5ish hours to look up the name of the util
01:27 PM Cromaglious_: I went to 4.9.13
01:28 PM Cromaglious_: From the stock 3.something kernel
01:30 PM IchGucksLive: {HD}: get more then one it may break
01:30 PM IchGucksLive: high em
01:31 PM {HD}: IchGucksLive: i 4 232-485 adapters. How do I tell what my serial port is? Dev/TTY?
01:31 PM IchGucksLive: ls etc/dev
01:31 PM IchGucksLive: there it shoes u p
01:33 PM {HD}: There is no etc/dev
01:33 PM IchGucksLive: ls /dev
01:34 PM {HD}: But in /dev there are tty-tty63 ttys0-ttys3
01:34 PM IchGucksLive: then i woudt grep it from the dmesg
01:34 PM Cromaglious_: You have a ttyACM0?
01:35 PM {HD}: When I grep serial it show ttys0
01:36 PM {HD}: Cromaglious_: no acm0
01:36 PM Cromaglious_: You using real serial ports?
01:36 PM {HD}: Yea
01:37 PM Cromaglious_: Then it is ttys0 thru 3
01:38 PM {HD}: Its working!
01:38 PM {HD}: But rpm doesnt match
01:38 PM IchGucksLive: you are the man of the day
01:41 PM IchGucksLive: GN8
01:42 PM {HD}: It works! but, the rpm is the werid @50Hz rmp and not actual.
01:49 PM Cromaglious_: Heh
01:50 PM Cromaglious_: Those are details....
01:52 PM Cromaglious_: Like when i was figuring out pid and was able to stop using two modules. Scale and sum
01:54 PM Cromaglious_: By using the native encoder.0.position-scale setting it to 3 magnets + 1/60 ended up 1/20 or 0.05 then encoder.0.velocity was rpms
02:11 PM {HD}: Hum, Guess ill try to read about it.
02:20 PM {HD}: Seems like maybe I need to use spindle-speed-fb instead of speed-command...?
02:20 PM {HD}: Not the best doc I have seen... http://www.linuxcnc.org/docs/html/man/man1/hy_vfd.1.html
02:21 PM Cromaglious_: There's alot of those... Read the one on 'not' module
02:24 PM Cromaglious_: What a fountain of knowledge there NOT!
02:24 PM Todd_Z: That one is a bit terse isn't it.
02:24 PM Cromaglious_: A bit....
02:24 PM {HD}: What is the NOT module?
02:24 PM Cromaglious_: Invert binary pins
02:26 PM Tom_itx: shouldn't really need it with mesa cards
02:27 PM Tom_itx: on the input atleast
02:30 PM {HD}: Can I send cmds to the vfd via terminal? How do I request values?
02:30 PM Cromaglious_: I think hal net lines need to be explained.. Like net NameToBeNeverUsedAgain0signal not.0.in parport.p.pin10 # net signal pin pin (pin ...) ; i
02:31 PM Cromaglious_: S/.p./.0./
02:32 PM Cromaglious_: Getting a handle on wether you can have multiple taking inputs from many pins outputs
02:33 PM Cromaglious_: Net b0sig pin.0.in pin.1.out pin.2.out
02:34 PM Cromaglious_: Or net b1sig pin.0.out pin.1.in pin.2.in pin.3.in
02:36 PM Cromaglious_: The trippy thing is pins can be virtual or physical
02:50 PM CaptHindsight: Cromaglious_: I agree. I was panning on writing an HAL guide
02:51 PM CaptHindsight: heh, only with better grammar and spelling
02:51 PM {HD}: I tried to use halrun but I think I broke it.
02:51 PM {HD}: lol
02:53 PM CaptHindsight: I'm running latency-historgram and the servo thread distribution in centered around -10uS
02:54 PM CaptHindsight: latency does go positive but it's only a few % of the overall, the base thread looks normal and it under 20uS jitter
02:55 PM CaptHindsight: I've never seen it act like this before
02:55 PM CaptHindsight: with the servo thread latency distribution so off center
02:59 PM Cromaglious_: What was the guy on that wrote wire which is based on
03:00 PM Cromaglious_: Which hal is based on
03:03 PM Cromaglious_: Hmm gonna see if i can find a service which cuts and grinds mt3 into r8
03:04 PM Cromaglious_: R8 has a pin too
03:04 PM gregcnc: anyone who rebuilds spindle should be capable, but it will probably cost more than a chinaspindle
03:06 PM CaptHindsight: Cromaglious_: what about the HAL wire? Who wrote HAL or?
03:07 PM Cromaglious_: Wire cam first... I think it was a commercial product. Then came HAL and followed wire conventions
03:08 PM CaptHindsight: I just wanted to write a clearer tutorial for non-programmers with clear step by step examples
03:09 PM Cromaglious_: I think I'll start naming my signal with sig0_blah, sig1_yadda, sig3_thingamabob
03:09 PM CaptHindsight: I noticed a few things missing like "exit" in the HAL manual to end a session
03:10 PM Cromaglious_: And add file name to it as well so you can find it
03:11 PM Cromaglious_: I haven't gotten to the part of doing math in the hal file...
03:11 PM CaptHindsight: HAL seems to be intuitive to programmers in general
03:11 PM CaptHindsight: if you're not it's a steeper learning curve
03:12 PM Cromaglious_: Has a reverse polish notation feel to some of it
03:14 PM CaptHindsight: I found a video on HAL but even the producer didn't fully understand it, he even says where he's making a good guess or it just works this way
03:15 PM CaptHindsight: https://www.youtube.com/watch?v=eIOVIyWpIDI audio isn't the best
03:16 PM andypugh: HAL confuses some programmers too, because it isn’t a programming language.
03:17 PM Cromaglious_: Net signalnamenevertobeusedagain onlyonepin.0.withoutputallowed anotherpin.0.whichisAnInput yetanotherpin.2.whichisAnInputToAnotherModule oranActualpinonaParport.0.pin10-out_which confusingly is an inputWhichOutputOnAPhysicalPin
03:17 PM andypugh: I got it fairly quickly because I have used LabVIEW a lot, so was reasonably comfortable with the idea of data-flow driven processing.
03:18 PM andypugh: Cromaglious_: signalnamenertobeusedagain can actually be used as many times as you want, in as many HAL files as you need to, to refer to the same net.
03:20 PM {HD}: I found an issue! I think this user space is calculating motor speed incorectly... http://www.linuxcnc.org/docs/html/man/man1/hy_vfd.1.html
03:20 PM Cromaglious_: I think thats the biggest hangup.. Inputs which have the name out on them. Because they are actual phtsucal pins
03:20 PM {HD}: It states "P011 as Max-freq" which is wrong.
03:21 PM {HD}: P011 is 'Freq lower limit"
03:21 PM {HD}: opposite of Max freq
03:22 PM Cromaglious_: But doesnt have to be...
03:25 PM Cromaglious_: On the way home, got in early for my 2pm ultrasound, dine and out the door at noon:38
03:25 PM {HD}: ultrasound? are you pregnant?
03:26 PM CaptHindsight: they sell them on ebay
03:26 PM {HD}: babies?
03:26 PM CaptHindsight: ultrasounds, you can have all sorts of fun with them
03:26 PM Cromaglious_: My every year ultrasound for pictures of my kidneys and bladder for the docs
03:26 PM CaptHindsight: ebay might have a ban on baby sales, you might have to try amamzon
03:27 PM Cromaglious_: <--- 20-30% kidney function left.
03:27 PM SpeedEvil: Do ultrasonic cleaners clean people?
03:28 PM SpeedEvil: Cromaglious_: yay >20%. Good luck
03:28 PM CaptHindsight: SpeedEvil: depends on how you define clean, but they have them big enough to turn you into gello
03:29 PM Cromaglious_: SpeedeVil yes they, too high of power they turn people into soup
03:32 PM CaptHindsight: hey no ultrasonic bath channel on youtube yet with "lets see whats happens when we put X into the bath"
03:32 PM {HD}: CaptHindsight: Million dollar idea!
03:32 PM CaptHindsight: X = various foods, insects, antique watches etc
03:34 PM CaptHindsight: samsung phone could be fun
03:52 PM R2E4_bevins: evenin,, mornin,afternoon
03:57 PM Loetmichel: CaptHindsight: that depends... my bath would be to small
03:58 PM Loetmichel: and not that many ppl have access to a swimming pool sized ultrasonic cleaner
03:58 PM Loetmichel: s/my bath/my US cleaner for example
03:59 PM DaViruz: my experience with ultrasonic cleaning is that it's not very spectacular
04:04 PM {HD}: I tired to add
04:04 PM {HD}: "-S 24000" to my loadusr hy_vfd and it is still not matching up.
04:06 PM CaptHindsight: Loetmichel: that's why some with large shredders, blenders, vacuum chambers etc have fun videos
04:07 PM Loetmichel: dont forget hydraulic pressses
04:07 PM Loetmichel: -s
04:08 PM Loetmichel: But IIRC the large shredder is a company that shamelessly shows off their merchandize.
04:11 PM {HD}: Anyone using hy_vfd? I edited the pyvfd to readout "24000" but setting "loadusr hy_vfd -S 24000" was still off. When the software read 5K the VFD read 4K...
04:12 PM andypugh: I am using it, but don’t actually know if the speeds are right.
04:12 PM {HD}: andypugh: does the software readout match the vfd readout? That is what I am trying to accomplish.
04:14 PM andypugh: I can’t see the VFD readout, it is in the back of the lathe cabinet
04:14 PM andypugh: https://forum.linuxcnc.org/38-general-linuxcnc-questions/32512-huanyang-vfd-won-t-communicate-get-errors?start=20#91121
04:14 PM andypugh: That forum post has somethings to say, but I am not sure what the conclusion was.
04:18 PM {HD}: andypugh: Hum, Ill take a look at my .ini file and see what is going on in there.
04:30 PM * Cromaglious_ wanders off reading about pid FF0,1,2
04:38 PM Deejay: gn8
04:40 PM Cromaglious_: Nite deejay
04:40 PM R2E4_bevins: Doing some error checking in remap......
04:40 PM {HD}: andypugh: Yep, now that I write down some #s I can see I have having the same results as the people in the post. It is a 20% error...
04:41 PM andypugh: motor rated speed is for 50hz, are you using a 60hz nameplate speed?
04:43 PM {HD}: andypugh: I am not sure what you mean. I have a 50Hz motor and I am entering the speed @50Hz but my power supply is 60Hz but I thought the VFD would take care of that stuff...
04:44 PM andypugh: Yes, it will. My idea only works if you are entering data for a 60Hz motor
04:45 PM andypugh: Have you tried a -S option? Does the rated_speed HAL pin match your programmmed PD144?
04:46 PM {HD}: andypugh: I set -S to 24000 because I believe there is a bug in the hy_vfd where it calculates off min and not max...
04:46 PM andypugh: Is that the number that ends up on the HAL pin?
04:47 PM {HD}: Calculates using P011 which is min frequency where I think they want to calculte speed with P005 which is max frequence...
04:47 PM {HD}: andypugh: Let me go back to the shop and check the pins...
04:49 PM {HD}: Rated motor rev 24000
04:53 PM {HD}: .Rott is correct value for vfd rotations.
04:57 PM {HD}: The problem is frequency...
04:57 PM {HD}: @50 it is only 2400 rott
04:58 PM {HD}: Oh shit.
04:58 PM {HD}: 144 got set to 2400...
05:00 PM {HD}: When I launch it changes the value of 144
05:04 PM andypugh: Yes, I think it sets PD144 if you have a -S value or change the HAL pin, or it reads PD144 if you have neither.
05:04 PM {HD}: Ok, I think I know what to try now.
05:06 PM {HD}: Yikes, that did not work
05:08 PM {HD}: Now its back to 1k in SF AND 8k on HW
05:16 PM {HD}: When I set –S 24000 then start software then change P144 to 3000(from 2400) it works.
05:19 PM {HD}: I don't know why -S 24000 sets P144 to 2400...
05:25 PM Cromaglious_: Grep your files for 2400, then 144, then 50
05:26 PM Cromaglious_: If you get returns check them out
05:27 PM {HD}: Cromaglious_: Just the files in the my mill folder?
05:29 PM Cromaglious_: Yep
05:36 PM Crom: home again
05:37 PM {HD}: I think the issue is the '-S' value...Im off to dinner but I will continue to figure it out when I get back.
05:49 PM Crom: heh back when we were a paternal society.. https://www.facebook.com/CaliforniaRightToCarry/photos/pcb.1272041842878636/1272041436212010/?type=3&theater

05:55 PM {HD}: just hit 'not now'
05:55 PM Tom_itx: then the reminder covers half the screen. no thanks
05:56 PM Crom: http://pasteboard.co/3a6G0hw0Z.jpg
05:58 PM _methods: gawd must have been awesome on a plane with a bunch of men just fartin it up and no women around to ruin it all
05:58 PM Crom: and BOOZE!
05:58 PM _methods: beer pong at 30,000'
05:59 PM Crom: Don't forget the REALLY cute young and domb stewies...
05:59 PM _methods: no women man
05:59 PM CaptHindsight: thank you for flying American Airlines where we beat the competition, not YOU
05:59 PM Crom: _methods: it's a DC-6... so more like 15000
05:59 PM _methods: tru forgot
06:00 PM Tom_itx: take it up to 20k for a real high
06:00 PM Crom: hope those engines had turbo's or super chargers
06:01 PM CaptHindsight: oh southwest https://thedirty.com/news/southwest-airlines-responds-alleged-ad-mocking-united/#post-2189850
06:01 PM _methods: bob dobbs approves of men only flights
06:02 PM _methods: omg finally getting to watch spicegirl try to explain himself in that press conference
06:03 PM Tom_itx: just leave off the whiney ass kids and i'd be ok with it
06:03 PM CaptHindsight: no babies or snakes after 5pm
06:03 PM Tom_itx: or just stuff em in the carry on compartment
06:04 PM CaptHindsight: I once flew 13 hours to Korea with 3 babies in the row in front of me
06:04 PM CaptHindsight: it was like a crying tag team
06:04 PM _methods: sweet jeebus
06:04 PM {HD}: I am going to check this out when I get back from dinner...maybe it has the config data I need...
06:04 PM {HD}: http://wapl.es/cnc/2015/12/04/huanyang-linuxcnc-2.7-speed-control.html
06:04 PM Tom_itx: were you purposely testing your noise cancelling headphones or what?
06:05 PM CaptHindsight: Tom_itx: they helped but 37 beers helped more
06:07 PM CaptHindsight: was a last minute trip, thought I had scored a 2nd row with leg room flight
06:07 PM CaptHindsight: then the bad news
06:07 PM CaptHindsight: was Korean Air, so at least it didn't crash
06:09 PM Tom_itx: Korean Roulette
06:10 PM CaptHindsight: I miss being able to buy a ticket at the gate
06:17 PM _methods: yeah it was kinda nice being able to wait with your family until it was time to board
06:31 PM Crom: I remember a flight from Korea to the states... Take of from narita in JP, eat a bird, dump fuel, land, mechanicals Look for an engine, find an engine, have it trucked over from Tokyo international, work really hard to get the engine changed by 10PM, don't... we are stuck for the night. Next morning, we are 1st flight out at 7am. Landing a anchorage, we lose a stabilizier on right wing. Another 10 hours looking for parts, getting parts, putting parts on
06:31 PM Crom: , loading plane. Fly from ankchoridge to Oakland at 15000' at 300knots.... Took bloody forever... I get off the plane 2 days late.
06:33 PM Crom: Tower Airlines of Up State New York... Their ONLY 747.... on contract to DOD to fly Saint Luis to Oakland to Anchorage to Narita to Osan, and retrace back to Saint Luis. Do this twice a week...
06:34 PM CaptHindsight: Crom: how long ago was this?
06:35 PM Crom: '88 just before the Olympics in Korean
06:36 PM Crom: Korea
06:38 PM Crom: Travel didn't believe me when I got my next base... 3 other people were checking in at that time had ALSO been on that flight...
06:39 PM Crom: At least one was a 1st Luiey
06:40 PM Crom: 29 years ago, next month...
06:40 PM Crom: Damn I feel OLD!
06:40 PM * jdh hands Crom a mirror
06:44 PM Crom: https://en.wikipedia.org/wiki/Tower_Air
06:44 PM Crom: yeah Tower Air
08:02 PM Crom: the X on this is so loosey goosey Z's not much better
08:10 PM Crom: fudge! tach 9v battery is dead
08:13 PM Crom: The one battery I don't stock at home... AA, AAA, LR44, 16850 Lion yes... 9v nope...
08:15 PM Crom: OK I have to use this carppy X and Z to make parts so I stiffen X and Z, then I can do gantry sides...
08:26 PM Crom: time to gt dial indicator and start measuring flex
08:28 PM Crom: holes in disk I have are 24.28mm time to look at linear bearings
09:12 PM Crom: ARGH@#&@# Heekscad is crashing everytime I try to cut a hole
09:12 PM BeachBumPete: try that 360
09:18 PM Tom_itx: what's pete been up to?
09:19 PM BeachBumPete: just working man how are you
09:19 PM BeachBumPete: had to make some simple brackets this afternoon
09:19 PM Tom_itx: good, not much going on here atm
09:19 PM Tom_itx: cnc related anyway
09:21 PM BeachBumPete: http://i.imgur.com/MGWhrGJ.jpg
09:22 PM Tom_itx: what for?
09:23 PM BeachBumPete: they are for a customer at work where I am doing some cabinet installations and trim work.
09:23 PM BeachBumPete: these are for a set of three rough sawn floating shelves that go in the kitchen area
09:23 PM Tom_itx: ahh that's right... i forgot you were back with the cabinet stuff again
09:24 PM BeachBumPete: they will be set inside the drywall screwed to the studs and then mudded over leaving only the shaft sticking out of the wall
09:24 PM BeachBumPete: so we can set the 2" thick rough sawn shelves on the rods to support them
09:25 PM Tom_itx: prolly should paint or clear coat them so the drywall doesn't rust them and bleed down the wall
09:25 PM BeachBumPete: think so?
09:25 PM Tom_itx: i would
09:26 PM Tom_itx: just a quick clear coat or something
09:26 PM BeachBumPete: they are mostly with the mill scale finish
09:26 PM BeachBumPete: I guess I could shoot some black paint on them
09:26 PM Tom_itx: they may be ok but if the drywall soaks up any moisture it will cause problems later
09:27 PM Tom_itx: even if it's just around the base
09:27 PM BeachBumPete: I will pop them outside and shoot some black on them in the morning
09:27 PM Tom_itx: the rod is all that needs coating really
09:27 PM BeachBumPete: I think they should work good tho other than that
09:27 PM Tom_itx: yeah
09:27 PM BeachBumPete: just drill a 3/4 hole in the back of the shelf and slide it on.
09:28 PM Tom_itx: i've had some of that metal corner trim for drywall bleed thru and do that
09:28 PM BeachBumPete: then I plan to drill a small hole from the top down thru the rod and then put a screw in each rod holding the shelf to the wall
09:28 PM BeachBumPete: they shold hold some weight pretty good I think
09:28 PM Tom_itx: yup
09:29 PM BeachBumPete: 3/8 plate and 3/4 rod
09:29 PM Tom_itx: make sure you get the holes straight in the wood
09:29 PM BeachBumPete: yeah
09:29 PM Tom_itx: i'd make a drill guide
09:29 PM Tom_itx: even if it's just to get them started
09:30 PM BeachBumPete: I am going to actually cut the drywall to mount the plates then using my router with a big flat plate I plan to machine the face of the stud just a touch to ensure it is flat to the face of the drywall before I screw them down
09:30 PM BeachBumPete: kinda spotfacing it
09:30 PM BeachBumPete: not that any of it is flat or even really
09:31 PM BeachBumPete: I am going to mount the plates then machine the shelves themselves and test fit before we close up the wall behind them
09:32 PM BeachBumPete: I also have to modify a couple scrolled steel brackets they bought at a craft show to be able to support a marble pass thru window shelf
09:32 PM BeachBumPete: two of them
09:32 PM BeachBumPete: then make a middle bracket to distribute the weight
09:32 PM BeachBumPete: which will get covered with more of the rough sawn cedar
09:33 PM BeachBumPete: Tom_itx did you see my newest anodized parts I posted the other day?
09:34 PM Tom_itx: no i don't think so
09:34 PM BeachBumPete: http://i.imgur.com/GCH0LY9.jpg
09:34 PM BeachBumPete: http://i.imgur.com/j0uBsge.jpg
09:35 PM Tom_itx: looks good
09:35 PM Tom_itx: you had those done didn't you?
09:35 PM BeachBumPete: yeah I have an agreement with a local plating company north of me
09:36 PM BeachBumPete: I basically ship them up and they do them and ship them back
09:36 PM BeachBumPete: saves me a bunch of frustration and running around
09:38 PM BeachBumPete: so far they have done a great job I think
09:38 PM BeachBumPete: the part is a LOT more red than the picture shows for some reason
09:46 PM Crom: Nice Rail!
09:46 PM BeachBumPete: thanks Crom
09:47 PM Tom_itx: sry, got interrupted here..
09:47 PM Tom_itx: looks pretty good
09:47 PM Crom: pict rail for scope dove tails?
09:48 PM BeachBumPete: huh?
09:48 PM Crom: the rails...
09:48 PM BeachBumPete: yeah
09:48 PM BeachBumPete: they are scope riser rails
09:49 PM BeachBumPete: with built in droop compensation for airguns
09:52 PM Crom: heh... yeah appogee on air guns is a killer... I once got into an argument with an instructor that couldn't believe that a weapon could be sighted to the appogee point of projectile path...
09:52 PM BeachBumPete: heh that is typically how we do it
09:52 PM Crom: so any shot not at sighting range would be below sight line
09:52 PM BeachBumPete: everything is a click up from there
09:53 PM BeachBumPete: close range shots are in the 40-50 clicks up range, say 10 yards or so then at 55-60 it is back up around there again depending on the droop angle and scope/projectile velocity
09:54 PM Crom: That instructor is dead and buried... but I ran into him again and he was still an ID 10 T virus carrier
09:54 PM Crom: when I got back from Korea in 88
09:56 PM Crom: Clackum was his name
09:56 PM Crom: ex army wore his CIB all proud like... came over to Air Foce after nam...
09:57 PM Crom: cradle robber too... his wife was 20 years his junior
10:03 PM Crom: Him and his wife were originally from the hills... Yeah those hills...
10:04 PM Crom: way back in those hollers
10:04 PM BeachBumPete: I need to come up with some new designs man
10:05 PM BeachBumPete: been working on a few things
10:05 PM BeachBumPete: but so far not anything earth shattering LOL
10:14 PM Crom: for paint ball or for anything/
10:15 PM BeachBumPete: anything really
10:44 PM Crom: hmmm since I learned too much about hal... I'm going back to working on my Arduino Mega Ether stepper
11:07 PM MacGalempsy: hello
11:07 PM DrippityDrops: MacGalempsy: evening!
11:08 PM MacGalempsy: making chips?
11:08 PM DrippityDrops: ugh im trying to think of a product and I just cant think of what the name of it is
11:08 PM MacGalempsy: fleshlight?
11:08 PM DrippityDrops: nah I got these automation projects keeping me busy, but yeah 8 hours a day the shop is running 5 screw machines
11:08 PM DrippityDrops: hajhaja
11:08 PM DrippityDrops: CLOSE!
11:08 PM DrippityDrops: okay so its this aluminum ring
11:09 PM DrippityDrops: and you put an air compressor on it
11:09 PM DrippityDrops: then you send a bar through it and it cleans the bar
11:09 PM MacGalempsy: no idea
11:09 PM DrippityDrops: this is killin me
11:12 PM Tom_itx: what sort of screw machines?
11:12 PM DrippityDrops: multispindle mostly
11:12 PM Tom_itx: brand?
11:12 PM DrippityDrops: davenport and acme
11:13 PM DrippityDrops: and 2 index machines
11:13 PM Tom_itx: i ran 6 & 8 spindle for several years
11:13 PM DrippityDrops: those are single spindle tho
11:13 PM Tom_itx: new brittan gridley
11:13 PM DrippityDrops: ahhh
11:13 PM DrippityDrops: brass?
11:13 PM Tom_itx: brass copper steel
11:13 PM Tom_itx: no copper i meant aluminum
11:13 PM DrippityDrops: those were good for the higher range rpm
11:13 PM Tom_itx: had copper on the brain
11:13 PM Tom_itx: larger stock eys
11:13 PM DrippityDrops: the acme-gridley were more for steel I think
11:13 PM DrippityDrops: slower machines
11:14 PM Tom_itx: we had those, davenport and brown & Sharp
11:14 PM DrippityDrops: do you know much about the davenports?
11:14 PM Tom_itx: nope never ran those
11:14 PM DrippityDrops: they are fun beast
11:14 PM Tom_itx: i had a manual for one here somewhere
11:14 PM DrippityDrops: I got one to run an 8 inch part
11:14 PM DrippityDrops: im looking at doing a lcnc conversion on one
11:15 PM Tom_itx: they ran long parts on them too but generally the davenports ran the tiny parts, brown & sharp ran the midrange parts and we ran the big ones
11:15 PM DrippityDrops: I have any extra sitting here and thing it would be an interesting machine to convert. ntm design and sell attachments for
11:15 PM MacGalempsy: we are drilling a hole today too, but no screws
11:15 PM Tom_itx: how deep are you now?
11:15 PM DrippityDrops: I did a cnc conversion on a machine almost identicle to brown and sharpe
11:16 PM DrippityDrops: its a well....
11:16 PM DrippityDrops: :P
11:16 PM MacGalempsy: 10102.39' still vertical
11:16 PM Tom_itx: how do they tell how straight it is?
11:16 PM MacGalempsy: there is a survey tool in the drill string
11:16 PM Tom_itx: ahh
11:17 PM MacGalempsy: it measures azimuth and inclination
11:17 PM DrippityDrops: plumb bob hangs in the coolant thru hole
11:17 PM DrippityDrops: its technical
11:17 PM Tom_itx: DrippityDrops any have cross drill attachments?
11:17 PM Tom_itx: etc
11:17 PM MacGalempsy: our coolant is 14.2lbs/gln oil based mud
11:17 PM DrippityDrops: yah
11:18 PM DrippityDrops: I got stop spindles on the davenport now, im looking at doing a servo tapping unit
11:18 PM Tom_itx: we had a couple new brittans that did
11:18 PM Tom_itx: one had a pickoff for a 2nd op to the back side of it
11:18 PM DrippityDrops: ok, do you remember what the "swing arm" is on a davenport? where the cutoff swung in on a pivot?
11:18 PM Tom_itx: sorta
11:19 PM Tom_itx: i didn't go in that room alot
11:19 PM DrippityDrops: regardless, I want to put that on a linear motion and rotary for XZ
11:19 PM DrippityDrops: haha yeah the davenports can get noisy huh>!
11:19 PM Tom_itx: there were probably 15-20 of each at least
11:19 PM Tom_itx: i ran 6 or so generally
11:20 PM DrippityDrops: you recall having an auxillary spindle in the newbritains?
11:20 PM DrippityDrops: the one which rode on the turret?
11:20 PM Tom_itx: no, one just had a pickoff attachment
11:20 PM DrippityDrops: okay yeah like a pickoff
11:20 PM Tom_itx: it had a saw on it to cut a screwdriver slot
11:20 PM DrippityDrops: I want to put that motion on servo for peck drilling and a spindle for tapping
11:21 PM DrippityDrops: ah the rotary slotting
11:21 PM Tom_itx: roll threads etc
11:21 PM DrippityDrops: yeah like winters threadrollers
11:21 PM DrippityDrops: lots of clever attachements
11:21 PM Tom_itx: i don't remember the brand but these were timed with 2 rollers
11:21 PM DrippityDrops: pneumatic?
11:21 PM Tom_itx: not that i recall
11:22 PM Tom_itx: this was like 25yrs back
11:22 PM DrippityDrops: just like yesterday and tomorrow to me
11:22 PM DrippityDrops: :P
11:22 PM DrippityDrops: ever get into rotary transfer machines?
11:22 PM Tom_itx: some were WWII surplus era and others were newer
11:22 PM Tom_itx: no
11:22 PM Tom_itx: turret machiens?
11:22 PM DrippityDrops: are you familiar with hydromat?
11:23 PM Tom_itx: they had some yes
11:23 PM Tom_itx: i never ran one
11:23 PM Tom_itx: they'd load forgings in and the turret would rotate the part to each station
11:23 PM DrippityDrops: i programmed this with linuxcnc
11:23 PM DrippityDrops: https://vimeo.com/212692659
11:23 PM DrippityDrops: yep
11:23 PM DrippityDrops: exactly
11:23 PM DrippityDrops: this is a profiling/boring bar attachment
11:24 PM DrippityDrops: for recessing and well profiling.
11:26 PM Tom_itx: early day tomorrow so i'm gonna call it a night
11:26 PM DrippityDrops: take care!
11:41 PM {HD}: Ok the only way I can get linuxcnc spindle speed to match the HYVFD speed is to "loadusr hy_vfd -S 24000" then once I start controller I have to set P144 to 3000.
11:56 PM Crom: OK On the Arduino Mega i can have 6 input lines read by interrupt, and another 6 read by polling. 9 PWM out pins any of those could be moved to the polled read pins. I have 8 dir out pins and 8 step out pins, and another 6 digital out pins. then I have the 16 analog inputs.
11:57 PM Crom: I'm thinking... using 2 pwm's to give me 16bit resolution for spindle.
