12:17 AM Sabotend_ is now known as Sabotender
02:43 AM Centurion_Dan: Hi. Anyone got linuxcnc working on a multi-spindle machine? I've been asked to rebuild the control system for an Excellon Mark 6 pcb drill/router.
02:47 AM Centurion_Dan: This one has 4 spindles - they have a common X axis, a shared Y axis (can move inter-dependently), and have a full independent Z axis for each spindle. I'm not yet sure if the spindles have independent motor control, but I'd assume so.
02:48 AM gloops: http://probeindustriesinc.com/excellon/images/Mark-V-DR.jpg
02:48 AM gloops: ive not done it but pretty sure linuxcnc can run more than 1 spindle
02:59 AM Centurion_Dan: yeah, next model up, and actually it has 5 spindles. Looks like they're a common Y axis too.
03:00 AM Centurion_Dan: the orig controller is a bit umm ancient ... 5.25" floppies...
03:08 AM gloops: i think..if all the spindles are working simultaneously on identical parts, you might get away with just hooking them up to one vfd, providing it can supply enough juice
03:08 AM gloops: there are people in here who know though, just a question of catching them actully here
03:08 AM XXCoder: in a hour or so maybe
03:09 AM gloops: if they all use the same speed at the same time, stop for toolchange etc, no need for independent control
03:10 AM gloops: linuxcnc will create the signal for 1 pwm 0-10v (if thats the method youre using) the vfd will convert that to power output, the spindles will pull what they need
03:11 AM gloops: (i think)
03:11 AM XXCoder: i dont know if can align all toolholders same way
03:11 AM XXCoder: unless its like corsel or something
03:11 AM gloops: but if each spindle has encoder...nah
03:12 AM XXCoder: if its by hand, then they all have to use different tool lengths
03:12 AM XXCoder: interesting machine design
03:13 AM XXCoder: linuxcnc is extremely flexiable im pretty sure it can run such
03:14 AM gloops: ive seen talk about it in here before, in fact Turboss made a router with 2 spindles i think, to mirror one another
03:14 AM gloops: just depends though, might have been fixed speed spindles, or manual speed control
03:20 AM gloops: well, my last few hours on this job this afternoon, freedom is a day away lol
03:59 AM gloops: it is absolutely slashing down and has barely stopped for the last week
04:14 AM Centurion_Dan: cool... to add to the confusion I want to use Devuan as the base OS...
04:14 AM Centurion_Dan: being a Devuan dev and all... ;-)
05:08 AM Tom_L: morning
05:25 AM jthornton: morning
05:37 AM XXCoder: yo
05:37 AM XXCoder: can 5 spindle machine be ran by linuxcnc?
05:51 AM gloops: was there any conclusion on the multiple spindles question?
05:54 AM jthornton: hmm, 1 X, 4 Y's and 4 Z's and 4 spindles...
05:54 AM XXCoder: Centurion_Dan: still in?
05:55 AM XXCoder: 5 spindle actually, he has larger version
05:55 AM gloops: i think you would need to treat them as rotary axis is you wanted independent control?
05:55 AM Centurion_Dan: yup... just having a play with 2.9 dev version I just built for Devuan.
05:56 AM gloops: although if they share 1 X, surely they are only used for duplicating work
05:58 AM XXCoder: ya was wondering how it would work
05:58 AM Centurion_Dan: I've only cast eyes briefly on the m/c so not 100% sure. Pictures indicate that both X and Y are common, and only Z and spindle speed and/or spindle on/off is independent
05:59 AM gloops: cant think of many reasons you would need different spindle speeds or z height if theyre all following identical paths
06:00 AM jthornton: having 4 Z's all moving the same distance should not be a problem
06:00 AM Centurion_Dan: independent z's would likely for tool adjustment only and retraction of any unused heads in a job.
06:01 AM XXCoder: yeah would have to independantly control Z since tool lengths are basically impossible to be same
06:01 AM XXCoder: you'd have 1 good part and 4 scrap maybe
06:02 AM Centurion_Dan: From what I read on the specs, it's got linear encoders for X and Y. Not sure if it's steppers or induction motors.
06:02 AM gloops: so independent z jogging, but shared g code
06:03 AM gloops: you can jog joints independently, but i dont think you can touch joints off
06:03 AM XXCoder: is it all spindle share x and y or is it indpendant, or one axis independant and one axis shared?
06:04 AM Centurion_Dan: all spindles share X and Y
06:05 AM gloops: you could have 5 joints 12345 on one z...youd have to zero all the joints then enter touch off for z as a whole
06:05 AM Centurion_Dan: I haven't had a good look yet. The m/c is designed for pcb drill and routing and presumably the 5 stations allow 5 copies of the same job at once.
06:05 AM Centurion_Dan: s/stations/spindles/
06:05 AM gloops: the axis control shouldnt be an issue
06:05 AM XXCoder: yeah gloops
06:06 AM Centurion_Dan: The owner is an electronics whizz that wants me to get it working for a pcb manufacturing line he's setting up.
06:07 AM XXCoder: for in house or selling service of making pcbs?
06:08 AM Centurion_Dan: I'm just in it for my linux expertise and mechanical engineering (fitter/turner/welder including a stint as a CNC operator)
06:08 AM Centurion_Dan: for selling pcb's.
06:09 AM XXCoder: cool
06:09 AM XXCoder: why I asked is that theres so many cheap pcb sellers now
06:10 AM Centurion_Dan: XXCoder - most of the equipment came from a defunct company the new owner used to work for - failed due mostly due to mismanagement.... there were rumours of some creative accounting too...
06:10 AM Centurion_Dan: Not so much in NZ...
06:10 AM Centurion_Dan: China yeah sure...
06:11 AM XXCoder: yeah good for local customers that dont want buy outside
06:12 AM Centurion_Dan: The owner has work for the line waiting in the wings... but he now needs to get this m/c running, and the old controller... 5.25" floppy's... 512K ram...
06:12 AM Centurion_Dan: I'm sure we can do better...
06:13 AM XXCoder: yeah
06:15 AM Centurion_Dan: Anyway, I've had success tonight in building the latest dev version of linuxCNC on Devuan, so that's good. Will have to setup a dedicated host with an RT kernel and then start deciding on what sort of interface hardware to play with.
06:16 AM Centurion_Dan: We're lucky to have the m/c full schematics on hand so that should help
06:17 AM XXCoder: that would help.
06:17 AM XXCoder: i built my own machine, but its simple machine and im not super skilled lol
06:18 AM XXCoder: im very much cnc machinist but not machine maker nor "home machinist"
06:18 AM XXCoder: so my job is running big machines
06:19 AM Centurion_Dan: I should hear back tomorrow more about the motors, encoders, limits etc and then we should be able to make decisions on the interface hardware required.
06:21 AM jthornton: looks like Devuan doesn't like systemd
06:22 AM Centurion_Dan: exactly ;-)
06:23 AM Centurion_Dan: Doesn't look like LinuxCNC has been infected so chances are I can simply use the debian packages.
06:23 AM jthornton: infected?
06:23 AM XXCoder: rather strong word heh
06:24 AM Centurion_Dan: tongue in cheek :-)
06:27 AM Centurion_Dan: jthornton: There was a time when some debian developers did nasty stuff to packages to "support" systemd in ways that would seriously break them for non systemd init. These days the number of packages that have binary dependencies on systemd that can't be worked around are pretty few.
06:27 AM jthornton: ah I see
06:28 AM Centurion_Dan: I'd be interested to see if systemd has a significant effect on latency and jitter compared against sysvinit or openrc etc.
06:29 AM jthornton: that would be interesting, I know that hardware vs kernel version has an effect on latency
06:30 AM jthornton: for example my J1900 has it's lowest latency with 4.4 and worst by 200% with 5.1
06:31 AM Centurion_Dan: It seems also interesting that LinuxCNC seems to favor pre-systemd releases of Debian too...
06:32 AM Centurion_Dan: is that ms or ns?
06:33 AM Centurion_Dan: oh... sorry that was kernel versions?
06:36 AM jthornton: the J1900 on 4.4 has ~30us latency on 4.19 ~150us on 5.1 ~250us
06:40 AM Centurion_Dan: that's rt kernel?
06:41 AM jthornton: preempt rt yes
06:43 AM Centurion_Dan: I'm running latency test on my laptop currently (quad i7 with 8GB ram) non-rt kernel and getting terrible looking numbers...
06:43 AM Centurion_Dan: although it's a rather busy m/c
06:43 AM XXCoder: its laptop
06:43 AM XXCoder: try disable everything power saving
06:44 AM XXCoder: power management
06:44 AM Centurion_Dan: yeah .. and intel shit.
06:44 AM XXCoder: but even after ultimately laptop design defeat it for low latency
06:44 AM Centurion_Dan: yeah.... I was just testing the packages I'd built.
06:46 AM Centurion_Dan: I'll spin some real hardware soon. Either an old amd Phenom x4 or something along that lines for testing.
06:46 AM Centurion_Dan: does the open source amd/ati gpu drivers do ok these days?
06:48 AM XXCoder: ati nooooo
06:49 AM XXCoder: heard they have better support but I had really nasty experence where uninstalling ati driver killed system by uninstalling basically everything
07:05 AM jthornton: running a latency test on a non real time kernel is a waste of time
07:06 AM jthornton: Centurion_Dan: those latency numbers are with Lubuntu 19.04 with the LXQT desktop

08:16 AM CaptHindsight: XXCoder: that is Debians fault not AMD's
08:17 AM CaptHindsight: used to be worse, non dependency dependencies removing half your system
09:29 AM Deejay: hi
09:45 AM cgi: what is a good source of buying foam for shaping/moulds?
09:47 AM methods_: you might try local sign shop supply places
09:47 AM methods_: they usually have lots of diff foam sheets
09:48 AM cgi: methods_, why do sign shops have foam sheets? they use them to make signs?
09:49 AM methods_: yeah
09:49 AM methods_: a lot of sign shops have cnc routers to make 3d signs
09:50 AM methods_: https://www.grimco.com/Catalog/Category/Substrates/FoamSubstrates
09:51 AM methods_: i personally have no idea the best place to buy foam for molds but i do know sign supply stores usually have some foam
09:59 AM cgi: methods_, is it safe to cut and work with foam? or do i need a air filter on my nose?
09:59 AM methods_: i have no idea
09:59 AM methods_: in my experience it's usually best not to eat the stuff you cut
10:00 AM methods_: snorting foam is probably a bad idea also
10:00 AM methods_: unless you're into that kinda stuff
10:00 AM methods_: then by all means enjoy yourself
10:00 AM cgi: lol
10:03 AM cgi: I am looking to get foam cuboids of size a feet/feet/feet - or do you i have to glue sheets to make them?
10:04 AM cgi: methods_, Sign shops seem to have more sheets of foam?
10:09 AM SpeedEvil: cgi: what sort of foam?
10:09 AM SpeedEvil: in principle, foam board factories cut 4*8 sheets from large ~5' or so blanks.
10:10 AM SpeedEvil: however, it is likely you can't those.
10:10 AM SpeedEvil: ^get
10:28 AM Loetmichel: cgipython: you can get them from foam manufactureres
10:28 AM Loetmichel: but not in single quantities i fear
10:29 AM Loetmichel: :-)
10:33 AM cgipython: so better to buy sheets?
10:35 AM Loetmichel: depends WHICH sort of foam
10:36 AM Loetmichel: if its the Polyurethane kind thats also used in doors and general insulation you could make a mold and just foam a few cans in there
10:36 AM Loetmichel: if you mean styrofoam: yes, buy sheets and glue them
10:37 AM Loetmichel: or try to get house insulation foam sheets in germany, they come up to 1' thick "sheets"
10:37 AM Loetmichel: (or other european countrys)
10:41 AM jym: QUESTION... if two 12ga wire ~= 10ga, what would three 12ga equate to?
10:45 AM cgipython: Loetmichel, https://www.homedepot.com/b/Building-Materials-Insulation-Foam-Board-Insulation/N-5yc1vZbaxx - which type of foam is good for molds?
10:46 AM cgipython: polisio insulation, or extruded polystyrene or expanded polystyrene?
10:47 AM Loetmichel: hmm?
10:47 AM jym: Interesting... https://web.archive.org/web/20071002202727/http://home.hiwaay.net/~rgs/awgcalculator.html
10:47 AM jym: cgipython: Molds for what?
10:48 AM Loetmichel: no, i meant: get some of those spray cans for insulating walls/foaming in door frames and foam your block yourself. but that stuff is not good for hotknifing. it stinks to high heaven
10:48 AM jym: foam in a can == polyurithane foam
10:48 AM cgipython: jym, I want to shape molds for fiberglass/cf.
10:48 AM jym: cf ???
10:48 AM Loetmichel: if you want to have styrofoam you have to buy it ready made
10:48 AM Loetmichel: jym: indeed
10:49 AM jym: Loetmichel: That link says 3x12ga ~= 8ga
10:49 AM cgipython: jym, carbon fiber
10:49 AM jym: OOhhh
10:50 AM jym: cgipython: So you want to shape molds using foam, then laminate with fiberglass/cf?
10:50 AM Loetmichel: cgipython: i wouldnt make glass/carbon molds out of ANY foam
10:50 AM jym: cgipython: one time use or reusable molds?
10:50 AM cgipython: one time
10:50 AM Loetmichel: not with at least some 10mm thick glass/heat resistant structural stuff between the foam and the mold surface at all
10:51 AM * Loetmichel used MDF sheets glued together for making GF/CF molds
10:52 AM Loetmichel: like this: http://www.cyrom.org/palbum/main.php?g2_itemId=7338
10:52 AM Loetmichel: (half mold for a wing tip tank for an RC jet
10:52 AM cgipython: Loetmichel, is that a reusable mold?
10:52 AM Loetmichel: cgipython: yes
10:53 AM jym: Loetmichel: what that take to carve, about 90 minutes?
10:53 AM Loetmichel: jym: 8 hours IIRC
10:53 AM jym: Daaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaamn
10:53 AM Loetmichel: 56Mb of Gcode ;)
10:53 AM jym: Loetmichel: WTF?!
10:53 AM Loetmichel: that mold is 800mm long
10:53 AM Loetmichel: just for size comparsion
10:53 AM cgipython: how big is that cnc?
10:54 AM jym: what is that in real dimensions?
10:54 AM Loetmichel: 1020mm by 1500mm by 160mm travel
10:54 AM jym: (I meant inches apx)
10:54 AM Loetmichel: divide by 24.4 .-)
10:54 AM Loetmichel: 25.4
10:54 AM cgipython: that CNC is costly as hell I am guessing?
10:55 AM Loetmichel: nope, it was about 4000 eur in materials
10:55 AM cgipython: Loetmichel, which cnc ? did you build it yourself?
10:55 AM jym: cgipython: depends, can get from china/ebay/amazon for around $200 depending on the size you need
10:55 AM Loetmichel: https://www.youtube.com/watch?v=cEG7-6zwpt4
10:55 AM Loetmichel: cgipython: yes
10:56 AM Loetmichel: https://www.youtube.com/watch?v=BUqo3zxv5Vo <- there it is at the new owners shop
10:56 AM Loetmichel: (my boss at that time sold his model business)
11:00 AM cgipython: Loetmichel, thanks. What do you use to generate gcode?
11:01 AM jym: Loetmichel: EPS is't "THAT" bad, that's what they use to make surfboards from for years
11:15 AM jym: Loetmichel: view-source:https://web.archive.org/web/20071002202727/http://home.hiwaay.net/~rgs/awgcalculator.html
11:21 AM Loetmichel: jym: object not found
11:22 AM jym: Loetmichel: Well, just view the first link I gave, rght-click and then view source
11:23 AM jym: Loetmichel: The author did a nice job documenting/commenting the code
12:07 PM CaptHindsight: anyone ever order anything from Misumi? I can't seem to get anything
12:21 PM jdh: I have
12:21 PM JT-Shop2: I have a catalog but never did order anything
12:21 PM CaptHindsight: website seems broken, phones don't rung
12:22 PM CaptHindsight: rung/ring
12:28 PM gloops: sounds like hes sleeping one off
12:51 PM jym: CaptHindsight: I contacted them via chat, they are having web and phones issues, and it's starting to come back now.
12:51 PM jym: CaptHindsight: bottom right corner... "CHAT https://us.misumi-ec.com/us/Contact.html
12:52 PM jym: CaptHindsight: noob
01:00 PM CaptHindsight: jym: chat stopped working earlier as well
01:00 PM CaptHindsight: jym: they must run Winders, did you help them get it all sorted out?
01:00 PM jym: I picked up 750/1500W inverter for $40 from HF, it ran a mini-frig AND 20" whole house fan, but the clips are too small and the terminals are whack. Need to find a connector... XT150? EC9?
01:01 PM jym: CaptHindsight: If it's M$, nope =)
01:01 PM jym: CaptHindsight: I was just pulling your leg is all =)
01:04 PM jym: Something around the 150A range
01:07 PM CaptHindsight: 150A, how mnay volts?
01:09 PM CaptHindsight: jym: http://www.klsele.com/products/Terminal-blocks/Wire-Terminals-Series/2095.html look for the BIG Mother -F series

02:26 PM Tom_L: it's 5 o'clock somewhere...
02:27 PM jym: Tom_L: What happens is 5 o'clock got elimiated everywhere????
02:28 PM Tom_L: on a friday? we're all doomed
02:28 PM jym: everyday... goes from 4 to 6
02:28 PM perry_j1987: went camping yesterday just got back
02:28 PM perry_j1987: time all screwed up heh

02:31 PM Tom_L: so does chad open or close at 5?
02:31 PM jym: revolving door
02:32 PM Tom_L: also, business' that advertise 'open 24hrs' or 'we never close' why do they have locks on the doors?
02:33 PM Tom_L: i've clearly met my quota for the week and plan no further work activity
02:36 PM Tom_L: JT-Shop, how's tuning preempt-rt going?
02:39 PM CaptHindsight: Tom_L: they don't really mean "never close"
02:39 PM CaptHindsight: like "unlimited data"
02:40 PM Tom_L: haha that's a good one...
02:43 PM CaptHindsight: ~25 years ago the underground tunnels under downtown Chicago flooded
02:44 PM CaptHindsight: forcing several "we never close" businesses to close
02:44 PM CaptHindsight: the news story showed many of the places not knowing which keys were for the doors
02:47 PM Tom_L: you know why they flooded?
02:48 PM Tom_L: i watched a story on that
02:48 PM CaptHindsight: Tom_L: pylons in the river were sunk too close to the tunnels and they broke through
02:49 PM perry_j1987: so what are some things to know for boring holes with endmills (helical)
02:49 PM perry_j1987: to get them to come out right size
02:49 PM Tom_L: yup
02:49 PM Tom_L: climb mill
02:49 PM CaptHindsight: https://en.wikipedia.org/wiki/Chicago_flood
02:50 PM Tom_L: they had that on engineering distasters
03:09 PM CaptHindsight: a telecom worked found the break but it wasn't leaking much so they didn't do anything until it completely ruptured
03:09 PM CaptHindsight: typical city workers
03:10 PM XXCoder: it had "NMY" all over it
03:10 PM XXCoder: er I meant "NMP"
03:12 PM CaptHindsight: https://youtu.be/coeeBc3bfMA?t=53 city "drain"
03:24 PM abrock: I'm trying to run a custom program (M100) which I placed in the directory "/home/cnc/subroutines/" with the name "M100" as executable (755). This is my ini file: http://paste.debian.net/1087881/
03:24 PM abrock: I re-started linuxcnc, even changed the machine name to make sure I edit the correct files but it always complains "Unknown m code used: M100"
03:24 PM Deejay: gn8
03:26 PM abrock: I also checked all the reasons http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m100-m199
03:41 PM abrock: weird, putting it in ~/linuxcnc/nc_files works
03:42 PM abrock: it also seems to be forbidden to kill the subroutine with SIGKILL, the NC program stops after that
03:47 PM Tom_L: is the sub called from a program or from the ini?
03:48 PM abrock: I have one process which runs all the time and takes a foto when receiving SIGUSR1. I have a second process which is called by the M100 command and which sends the SIGUSR1 to the first process. Afterwards it waits until it is killed.
03:48 PM abrock: The first process takes a foto and then kills the M100 process
03:49 PM abrock: very brutal affair, all that processing and killing ;-)
03:49 PM Tom_L: may not matter but did you try adding a space between the =M100
03:49 PM Tom_L: probably doesn't matter
04:11 PM JT-Shop: Tom_L: for the J1900 I quit trying after getting ~30us
04:11 PM JT-Shop: but have found out a few more things about building the kernel and turning off the damn governor lol
04:11 PM Tom_L: i wasn't sure after all the pointers handed out in -devel you might try something new
04:12 PM JT-Shop: I probably missed most of them lol
04:13 PM Tom_L: abrock, i have an "M100" but it's in the main nc_files directory
04:13 PM Tom_L: :)
04:13 PM JT-Shop: yea M100 files need to be on a path set by the ini file and executable
04:13 PM Tom_L: looks like a shell script
04:15 PM JT-Shop: abrock: what version of LinuxCNC are you running?
04:16 PM abrock: 2.7.14
04:19 PM JT-Shop: alright you have the same path configured twice /home/cnc/subroutine, no need to do that
04:19 PM abrock: it's weird, the documentation says that PROGRAM_PREFIX is searched for M1xx _before_ subroutine path and user M path in [RS274NGC]
04:20 PM JT-Shop: yep so if you have a M100 in program prefix that is bad then the one in /home/cnc/subroutine will never be found
04:20 PM abrock: but that wasn't the problem, the problem was that LCNC complained about not finding a M100 program at all
04:21 PM JT-Shop: alright is the file executable?
04:21 PM abrock: ah, the docs say the other paths are only searched if [DISPLAY]PROGRAM_PREFIX is not specified
04:22 PM abrock: that's kinda unexpected, I would expect that every search path specified anywhere is searched until either the program is found or no more search paths are available
04:22 PM JT-Shop: no, the search order is program prefix if not specified then search nc_files then search the list in rs246ngc
04:23 PM abrock: I solved it by putting the M100 file into the ~/linuxcnc/nc_files directory, works now.
04:23 PM JT-Shop: that suggests a typo in your path for user m path
04:29 PM jym: Tom_L: why building a new kernel?
04:30 PM jym: Hey, can anyone suggest a reasonabley nice microscope?
04:30 PM jym: ...for shop/workbench use
04:31 PM abrock: what kind of object do you want to look at and why?
04:32 PM jym: PCB's, small parts
04:33 PM jym: I guess they call them industrial microscopes... https://www.microscope.com/stereo-microscopes/industrial-inspection
04:33 PM XXCoder: at work we have zoom in thing that can measure stuff quite accurately
04:33 PM XXCoder: interesting
04:35 PM jym: https://www.microscope.com/stereo-microscopes/industrial-inspection/omano-om2300s-gx4-zoom-stereo-boom-microscope.html
04:36 PM jym: XXCoder: Yeah, I used to work with a microscope that allowed you to measure the thickness of coatings
04:37 PM jym: But these were bosch lome microscopes, I dont seem them anymore
04:37 PM jym: (sp)
04:38 PM jym: Not that it has to me, just what I used at the time
05:16 PM Tom_L: jym what power microscope?
05:17 PM Tom_L: that looks like the one i've got
05:18 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/scope/scope1.jpg
05:21 PM Tom_L: i forget what power it is
05:22 PM jym: Tom_L: Yeah, something like that, but honestly I don't know what "power" I want/need
05:23 PM Tom_L: you don't want too much if you want to work under it
05:23 PM Tom_L: definitely want zoom
05:23 PM jym: I have a bench magnifying lens (5") now, and I believe it's 2.25x (5 diopeter) and I'd like 4x, plus zoom
05:24 PM Tom_L: i could go check...
05:24 PM jym: No rush
05:25 PM jym: I really have no clue till I see it, no pun intended, well, maybe a little pun ;)
05:25 PM jym: PCB traces, to seeing the burr on a knife edge
05:26 PM Tom_L: mine is good for that
05:26 PM jym: and MAYBE being able to use a DSLR camera for capturing things, but that's just a nicety
05:27 PM mozmck: ugh, trying to use debian is a pain
05:27 PM Tom_L: if you _ever_ might wanna take a pic get the trinocular though
05:27 PM jym: and sometimes just plain old thru hole soldering, cold joint inspections etc
05:28 PM Tom_L: good for that too
05:29 PM jym: https://www.microscope.com/stereo-microscopes/industrial-inspection
05:30 PM Tom_L: iirc mine might be 7 x 45
05:34 PM jym: yours sure looks looks like the ones on that link I gave, where did you get yours Tom_L?
05:35 PM jym: and I think you need 2 more displays =)
05:39 PM Tom_L: it's not marked on the scope but i'm pretty sure that's what it is
05:39 PM Tom_L: mine is amscope
05:40 PM Tom_L: https://www.amscope.com/7x-45x-stereo-zoom-microscope-with-single-arm-boom-stand.html
05:40 PM jym: Heh, I suspect it'a all the same, just OEM'ed
05:40 PM Tom_L: i put a clear filter under mine to keep solder spatter out of it
05:40 PM Tom_L: easier to clean
05:41 PM jym: play the video and tell me if that doens't look like yours? https://www.microscope.com/stereo-microscopes/industrial-inspection/omano-om2300s-gx4-zoom-stereo-boom-microscope.html
05:42 PM Tom_L: they're all about the same
05:42 PM Tom_L: some have a lighter base
05:42 PM Tom_L: or shorter arm
05:44 PM jym: Yours seems cheaper too
05:45 PM jym: Tom_L: what "clear lens" did you use?
05:47 PM Tom_L: iirc maybe a uv lense or something
05:47 PM Tom_L: it's an odd size
05:47 PM jym: Yeah, I would use a UV lens on my 35mm DLSR lenses, but the odd size is the gotcha
05:48 PM Tom_L: probably got that from b&h
05:48 PM jym: ah ok
05:48 PM Tom_L: one sec
05:49 PM jym: I got my Nikon D70 camera bag stolen out of my car year ago. Just got a D3400 from a pawn shop for $215 out the door and very happy with it
05:49 PM jym: years*
05:49 PM jym: No more $3400 camera bags now tyvm
05:49 PM Tom_L: 52mm hoya UV
05:50 PM jym: Ok, that's not bad
05:50 PM Tom_L: https://www.bhphotovideo.com/c/search?Ntt=52mm%20hoya%20uv&N=0&InitialSearch=yes&sts=ma&Top+Nav-Search=
05:51 PM Tom_L: i would get it and make sure it's the same before you get a filter
05:51 PM Tom_L: it probably will be
05:52 PM jym: Yeah, not in a super rush. I'm just HOPING it would be covered under HSA
05:52 PM jym: Since they cover magifying lenses
05:53 PM jym: or did in 2018 at least
05:54 PM jym: Tom_L: did it come with a light?
06:03 PM Tom_L: no
06:04 PM Tom_L: i just use my magnifier light
06:04 PM Tom_L: you can get them i'm sure
06:04 PM jym: ok
06:23 PM Centurion_Dan: Isn't it cheaper/better to get dedicated industrial camera's?
06:29 PM Centurion_Dan: jym: I did a job many years ago with a film capture system. It used a modified film projector, a special lightsource and an industrial camera that was triggered by the claw that pulled each frame into place. It was good for about 12 frames/sec using an optic sensor that was recycled from an old ball mouse.
06:40 PM jymm: Centurion_Dan: Well, I'm looking at a microscope, but it might be nice to be able to photogrpah some things. I just alreayd have a nice DSLR camera
06:42 PM XXCoder: glass top jog table with light from bottom, and camers has top light shining down to part
06:42 PM XXCoder: both lights adjustable
06:42 PM XXCoder: place high precision encoders on wheels done
06:42 PM XXCoder: problem is camera wont be isomorphic
06:42 PM XXCoder: but precision enough I would think, can take picture, and measure
06:50 PM jymm: Tom_L: Is that a GhettoScope we're talking?
06:50 PM Tom_L: it's chinaco if that's what you mean
06:51 PM Tom_L: pretty sure anyway
06:54 PM Tom_L: https://www.amscope.com/about-amscope-store
06:55 PM sliptonic: ok, somebody help me think this through. I've configured my scara robot so all joints are homing nicely. When I jog the Z axis down, it physically moves down, but moves 'up' in the 3d window.
06:56 PM sliptonic: traj coordinates are XYZC and Display geometry is the same
06:57 PM sliptonic: If I switch display to XY-ZC Then the motion is coordinated right but everything else is upside down.
07:11 PM jymm: Tom_LNo, I mean what you were desribign (glass, and encoders, etc) sounds like a Z axes and camera and lights
09:52 PM flyback: Tom_L, https://www.youtube.com/watch?v=yaWADN3SDos
09:53 PM XXCoder: that initially looked like mini fish pound setup
09:53 PM XXCoder: then drill engine huuuh heh
