12:08 AM Bleepshop: solarwind: Yeah, Oxy-Acetylene is nice. Old coat hangers make great fill rod for steel. LOL
01:28 AM Deejay: moin
01:35 AM CaptHindsight[m]: breaking c-log
01:36 AM CaptHindsight[m]: no clue
02:21 AM * Bleepshop yells "BOO!" at c-log.
03:11 AM -!- #linuxcnc mode set to +v by ChanServ
04:58 AM Tom_L: morning
04:59 AM Tom_L: 11°F & light snow
05:12 AM JT-Cave: morning
05:12 AM JT-Cave: 28°F no snow yet
05:13 AM JT-Cave: coop uno 39.875°F coop deux 43.8°F... need to format coop uno better
05:14 AM Tom_L: give it another 15min and it may be snowing
05:14 AM Tom_L: seems the heaters are doing their job
05:46 AM * JT-Cave goes to look
06:01 AM JT-Cave: nothing yet here
06:02 AM JT-Cave: yeah the real test will be tomorrow night with a forecast of 11°F
08:05 AM unterhaus_: weather undergroud says mostly sunny, failing to mention 1.3" of snow is forecast
08:12 AM JT-Cave: snowing here
09:13 AM Loetmichel: *cough*. just got my tax slip for last year... 33k6€ taxable income... ~9k income tax alone... not to mention unemployment, health and retirement insurances... :(
09:34 AM aaroncnc: well seems i get the fun of boiling circuit boards again to remove the epoxy. kinda wish i had access to LN2
09:51 AM JT-Shop: I used to get out in this kind of weather and plow the driveway and road but I'm just going to wait for it to melt!
10:07 AM aaroncnc: that reminds me i have to add fix the snowblower carb to my list.
10:16 AM aaroncnc: any one here played around with a K40 laser cutter?
10:18 AM pcw-home: A ~70' Eucalyptus tree fell on our fence, sure hope its from the neighbors property...
10:25 AM JT-Shop: ouch
10:28 AM pcw-home: Had to prop what's left of the fence up with some T posts temporarily to keep the sheep in
10:28 AM st[m] is now known as st
10:30 AM st is now known as struf
10:30 AM pcw-home: Our side just got hit by a main branch (maybe 40 ft long) The main section (maybe 3ft diameter trunk) just missed an apartment building
10:31 AM pcw-home: (fell the other way)
10:34 AM Lcvette[m]: Doh, would they have to pay for it pcw-home
10:36 AM * roycroft wishes he had a portable saw mill
10:37 AM struf is now known as struf[m]
10:41 AM pcw-home: I hope so (and we don't have to remove it) My toy chain saw is not up to the task
10:42 AM roguish[m]: lcvette[m]: this is Cal. it's an 'act of nature...'
10:42 AM roguish[m]: pcw-home: that's a tough one pcw...... good luck.
10:47 AM Lcvette[m]: Asking because my neighbor has a tree with branches over our driveway and I have asked repeatedly for him to please trim it but he refuses, it drops smaller branches all the time, to date none have damaged any cars, but of course it is just a matter of time
10:50 AM roycroft: in most jurisdictions you can trim it right up to your property line
10:50 AM roycroft: the only caveat being that you may be liable if your trimming kills the tree
10:51 AM roycroft: that does not happen in most cases, and you can probably cut it in a vertical plane right on the property line
10:52 AM roguish[m]: lcvette[m]: in Cal, one is free to take a chainsaw and go straight up the property line... but that's not 'happy neighbor'
10:52 AM roycroft: if you do not trim it, and your neighbor refuses, if a branch does damage your property your neighbor is liabe
10:52 AM roycroft: liable
10:52 AM roguish[m]: roycroft: not sure aabout that in Cal.
10:53 AM roycroft: best to negotiate with the neighbor
10:54 AM roycroft: and if the neighbor refuses, prepare to do some trimming, but make sure that the trimming is a spectacle that is certain to get the neighbor's attention, and start the trimming slowly
10:54 AM roycroft: there's a good chance the neighbor will run over and be more willing to negotiate
10:54 AM roguish[m]: my back neighbor has a large oak tree hanging over my fence into my yard. when I bought, 24 years ago, it was pretty and about half way to the house. now it's actually got branches over the house...... I had it trimmed once and they didn't even help with a penny. cheap bastards.
10:55 AM roycroft: neighbors, generally, are not as neighborly now as they were in times past
10:56 AM roycroft: social media has exacerbated that trend
10:59 AM Lcvette[m]: Yeah, I was thinking I may have it trimmed over the driveway
10:59 AM Lcvette[m]: It's a pain having to pickup branches before mowing each time.. and this thing sheds branches pretty bad
11:02 AM * Lcvette[m] uploaded an image: (729KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/fDtjBPwqAYtarurKgVWzAPcJ/IMG_20220106_114622132.jpg >
11:25 AM roguish[m]: lcvette[m]: ya really gotta know the local codes, and your insurance, and happy neighbors are always better that fence wars.............
11:33 AM unterhaus_: yeah, the second trunk is coming down sooner or later, probably
11:34 AM unterhaus_: should have been pruned at the beginning
11:36 AM unterhaus_: we have a row of trees that were planted too close to the property line, makes me feel like a bad neighbor even though I didn't do it
11:37 AM unterhaus_: it's possible it was by agreement, but maybe not
11:43 AM Lcvette[m]: unterhaus_: yeah for sure its gonna come down, one big ice storm or hurricane and its probably gona fall.. and it is only going to fall one way... into the house. /o\
11:43 AM unterhaus_: specifically, your house
11:52 AM Lcvette[m]: this neighbor started out nice enough, i helped him while he was building his house will welding some equipment and machined some replacement parts for one of his tractors that broke down so he could get back to work, no charge, happy, friendly, to help him out. always polite friendly etc.. The issues started while a landscape service that was coming by to do some annual maintenance we have done about once every 3 months or so and while
11:52 AM Lcvette[m]: they were here the neighbor ran them off threatening them. The neighbor owns a landscape business, and had a problem with how they were putting out the pine straw for the adjoining beds. I am not one to like mixing business with neighbors as it almost always leaves one side feeling less happy with the arrangement and I would never use him because of that fact, the same way i would not charge him and would rather do a favor to avoid that
11:52 AM Lcvette[m]: awkward scenario.
11:53 AM Lcvette[m]: s/will/with/
11:53 AM roguish[m]: lcvette[m]: take the high road. it's hard sometimes, but better.
11:57 AM Lcvette[m]: he is just a grump, the neighbor on the other side of him can't stand him either and actually went to court because he took down trees in their yard, they won and he was forced to plant somewhat matured replacements, and they don't get along. he also went after another landscape company working on the neighbors house across the street.. so suffice it to say im confident the problem lies with him as we all get along great. so now he has his
11:57 AM Lcvette[m]: new house in a neighborhood where no one likes him
11:57 AM Lcvette[m]: i feel bad for his wife who is very sweet
11:59 AM Centurion_Dan1 is now known as Centurion_Dan
12:25 PM Centurion_Dan1 is now known as Centurion_Dan
12:56 PM unterhaus_: "This is not something that LinuxCNC does or does not do"
12:58 PM unterhaus_: Quote from PCW. I'm not sure why he was wasting time reading that thread though

01:09 PM hazzy[m]: Legos for grown ups 😂
01:10 PM hazzy[m]: Happy New Year everyone
02:14 PM andypugh: XXCoder:Did you get the ER version of the touch probe? I have much-improved it and also fixed the download link.
02:14 PM andypugh: https://a360.co/3HHQlHs
02:14 PM andypugh: You were wanting ER16 I think? That’s a pretty easy change.
02:18 PM t4nk_freenode: andypugh, did you design that?
02:18 PM andypugh: Yes
02:19 PM t4nk_freenode: mmmm is that 3d printed?
02:20 PM t4nk_freenode: seems like pretty tough to build
02:21 PM aaroncnc: reminds me of this item i have had my eye on. https://www.aliexpress.com/item/1005003487684742.html
02:22 PM -!- #linuxcnc mode set to +v by ChanServ
02:22 PM -!- #linuxcnc mode set to +v by ChanServ
02:26 PM andypugh: Here is an ER16 version: https://a360.co/3n15pIk
02:27 PM andypugh: aaroncnc: A better bet (and made by a LinuxCNC-er, he wrote the probe screen macros) https://vers.by
02:27 PM JT-Shop: snow finally melted off the dish...
02:28 PM andypugh: t4nk_freenode: It’s actually surprisingly easy to build… https://youtu.be/2ia1_NKQJKs
02:28 PM aaroncnc: andypugh, is that site broken or is it just me?
02:30 PM andypugh: aaroncnc: It seems to be defaulting to the mobile version
02:31 PM andypugh: It was working just fine a couple of days ago
02:34 PM JT-Shop: works for me but I need to watch it in the morning during free time
02:34 PM aaroncnc: it looks nice the only small nitpick is the adjustment being on the bottom vs the side. but looks great
03:09 PM t4nk_freenode: yeah, that's very nice, andypugh
03:10 PM t4nk_freenode: I got a mere er11 collet though
03:12 PM XXCoder: andypugh: thanks
03:21 PM t4nk_freenode: I'm starting to get a bit mad myself now...
03:21 PM t4nk_freenode: I put all new and better collars on
03:23 PM t4nk_freenode: and I also drilled some holes through the y-axis tubings, put some bolts through, to fix them
03:23 PM t4nk_freenode: I managed to make 1 pcb, holes were in the right location too, after homing inbetween
03:24 PM t4nk_freenode: but I tried anotherone yesterday, and the holes were off again after homing
03:24 PM t4nk_freenode: don't know if I did something wrong
03:24 PM t4nk_freenode: but I'm having a bad time measuring/adjusting the backlash
03:26 PM t4nk_freenode: now I might make another small machine after all; I have some belt on a roll, some toothed pulleys.. bearings to last 3 lifetimes
03:27 PM t4nk_freenode: might just start designing something, you'd think that with the belts I could eliminate any backlash
03:28 PM t4nk_freenode: also thinking I might make 2 axes, and bolt those onto my existing machine so I can keep the z as it is
03:28 PM t4nk_freenode: I'm giving it one more try with a pcb first, see what happens
03:31 PM t4nk_freenode: I guess the tolerances are fine for a router, but this whole matter is destroying my soul ;)
03:32 PM t4nk_freenode: I want some precision, for crying out loud
03:40 PM t4nk_freenode: (technically I have exactly that though: precision that makes me cry out loud)
03:57 PM Tom_L: give em what they want and they're still not happy!
04:09 PM t4nk_freenode: ;)
04:10 PM * t4nk_freenode gestures up to the Heavens, holding a giant invisible watermelon
04:10 PM t4nk_freenode: well, the holes are situated ok now
04:12 PM t4nk_freenode: but some traces didn't quite separate
04:12 PM t4nk_freenode: I'm trying to go over it again, but I threw away the darned height map
04:31 PM roycroft: are any of you familiar with this probe?
04:31 PM roycroft: https://drewtronics.org/product/s5000led-wired-cnc-probe/
04:31 PM roycroft: it seems a decent price for what it is
04:32 PM roguish[m]: roycroft: Lcvette is. actually is a buddy of his.
04:32 PM roycroft: i'm thinking about puting it on my list of things to get
04:33 PM roycroft: i could use it in the cnc router even, as well as my mill
04:33 PM roguish[m]: this is Lcevette's website: https://smallshopconcepts.com/
04:34 PM roycroft: i was just watching a video about how a someone replicates cast, machined parts on a benchtop cnc mill
04:34 PM roguish[m]: He's always on the QtPyVCP channel
04:34 PM roycroft: he uses that probe to locate all the machined surfaces, then draws them in a solidworks part file
04:34 PM roycroft: then he underlays a picture of the part and traces the casting outlines onto the solidworks part
04:35 PM roycroft: then does the usual deciding on the machining operations and feeding the file to his cam plugin
04:38 PM roycroft: i'll have a chat with lcvette some time, and put it on my maybe list for now
04:39 PM roycroft: a lot of the cnc router folks get a metal homing standard that they set on the corner of their spoil board, and probe that
04:39 PM roycroft: with a conductive probe
04:39 PM roycroft: that never made a lot of sense to me
04:40 PM roycroft: i'd rather probe the actual part to home
04:56 PM JT-Shop: hmm I have a bird in the machine shop... I'm not going to open all the doors to let it fly out... too cold
04:57 PM JT-Shop: guess I'll put out some boss for it
05:01 PM roycroft: i just remembered
05:01 PM roycroft: today is friday
05:01 PM roycroft: yay!
05:01 PM * roycroft has the next five fridays off for vacation
05:01 PM JT-Shop: Saturday for me... I get 3 in a row
05:01 PM Tom_L: plenty of time to make pizza
05:01 PM JT-Shop: just because
05:02 PM JT-Shop: https://gnipsel.com/images/chickens/elevated-dust-bath/edb-05.jpg
05:02 PM JT-Shop: https://gnipsel.com/images/chickens/elevated-dust-bath/edb-06.jpg
05:02 PM roycroft: yeah, i could even make the dough from scratch tomorrow, except i already bought a doughball
05:02 PM JT-Shop: got a lot done on the top part... working on sizing the material for the legs
05:03 PM Tom_L: you like woodworking over metal?
05:04 PM Tom_L: more uses around the house i suppose
05:05 PM roycroft: well i'm impressed
05:05 PM roycroft: i'm resetting configs/passwords on a bunch of old network gear in preparation for donating it to a local non-profit
05:06 PM roycroft: i just plugged in one of our old edge routers that's been sitting on a shelf for about 8-9 years
05:06 PM roycroft: when it booted up i did a "show hardware" to get the hardware inventory
05:06 PM roycroft: that command also displays the current date and time
05:06 PM roycroft: it was off by less than a minute
05:07 PM roycroft: the machine has been powered off for all those years, and it is not connected to a network, so it was not able to sync the clock when i powered itup
05:10 PM roycroft: it's 16 degrees right now, and partly sunny
05:10 PM roycroft: i should do some grilling for dinner tonight
05:11 PM Tom_L: it is 10F here
05:13 PM roycroft: that's not good grilling weather
05:23 PM Alicrow: Can anyone recommend a good servo driver that can handle 3/4 HP 60V DC servos with tachometer?
05:25 PM Tom_L: https://www.geckodrive.com/servo-motor-controls.html
05:25 PM Tom_L: maybe
05:28 PM Alicrow: My worry with that Gecko is that it just does step/dir input and closes the encoder loop at itself. From what I understand, isn't it better to close the encoder loop at LinuxCNC so that it knows the actual position?
05:40 PM cradek: I don't think you'll find aftermarket velocity mode servo amps.
05:41 PM Alicrow: They all use step+dir?
05:41 PM cradek: when I've retrofitted machiens with tachs like that I've always used the original servo drives, no matter how old
05:42 PM cradek: one I've done and still have is from the 70s
05:43 PM CaptHindsight[m]: Alicrow: what type of servo motors? DC brushed, AC, etc??
05:43 PM CaptHindsight[m]: nevermind, brain fog prevented me from reading your post properly
05:43 PM Alicrow: Unfortunately, we don't have the original servo drives. The original controller died years ago and the whole control cabinet was scrapped or something, long before we got it.
05:46 PM Alicrow: So in terms of electricals, we have the servos, encoders, limit switches, and a new spindle motor (somehow the one we got with it was the wrong motor). Plus two solenoids for coolant spray system and spindle brake (without a coolant system or brake to hook them up to)
05:59 PM JT-Cave: tonight low 8°F
06:15 PM CaptHindsight[m]: at 8°F here now, going to -3
06:18 PM JT-Cave: dang that reminds me of Alaska in the spring time
06:19 PM Alicrow: Wish we got more low temperatures like that. Got a lot of snow on Monday, but it's all melting now because the temperature likes to hover just above freezing.
06:19 PM CaptHindsight[m]: Alicrow: http://www.leadshine.com/UploadFile/Down/DCS920d-G.pdf
06:19 PM Tom_L: low 9°F here
06:20 PM JT-Cave: now that the door is close Coop Uno is starting to rise in temperature up to 29°F now
06:21 PM Tom_L: i dunno if mesa makes a servo driver?
06:21 PM JT-Cave: aye Peter makes one but forget the amp rating
06:21 PM CaptHindsight[m]: http://www.mesanet.com/motioncardinfo.html 7i29
06:21 PM CaptHindsight[m]: H bridge type
06:22 PM * roycroft will be grilling tonight
06:22 PM Tom_L: and the openservo thing
06:22 PM roycroft: the rain will return tomorrow
06:22 PM Tom_L: that might work as well
06:22 PM Tom_L: but you'd have to build the board
06:22 PM roycroft: i did repair my main gazebo last summer, but i did not have time to repair the grill gazebo, so the grill sits out in the rain
06:23 PM roycroft: that will be my springtime project
06:23 PM CaptHindsight[m]: a gazebo for every appliance
06:23 PM * JT-Cave wanders upstairs for some Texas Chili con Carne with no beans
06:23 PM roycroft: i only have the two
06:24 PM roycroft: so it's really carne sin chili
06:24 PM CaptHindsight[m]: could be a Python skit
06:24 PM JT-Cave: not really it's Texas chile
06:25 PM JT-Cave: beans are not chili
06:25 PM JT-Cave: Texas chili
06:25 PM JT-Cave: chili with an i
06:25 PM roycroft: another reason not to be in texas then :)
06:25 PM roguish[m]: JT-Cave: got a recipe ????
06:25 PM JT-Cave: aye
06:26 PM JT-Cave: https://gnipsel.com/recipes/index.html
06:26 PM roycroft: i'm going to go work on my hot end wiring harnass
06:26 PM JT-Cave: I don't add the masa any more
06:26 PM roguish[m]: ah, cool, thanks
06:26 PM roycroft: now that i have all the parts and connectors
06:26 PM roycroft: i should be squirting really fast soon
06:27 PM Tom_L: have some chili and you might as well
06:27 PM JT-Cave: hmm I removed I see
06:27 PM JT-Cave: well no
06:27 PM roycroft: i eat chili often
06:27 PM roycroft: i don't get gassy from it
06:28 PM roycroft: and as i don't eat meat, my chili has a lot of beans init
06:28 PM roguish[m]: I'm gonna make some chile and cornbread this weekend.....mmmmm good.
06:28 PM JT-Cave: roguish[m], https://gnipsel.com/recipes/chicken/cider-brine.html
06:28 PM roycroft: i guess beans don't affect me like they do for most folks
06:28 PM JT-Cave: that's real good
06:28 PM roycroft: yes, but are you going to make yankee corn bread or real corn bread?
06:29 PM JT-Cave: I never make yankee corn muffins
06:29 PM roguish[m]: not sure of the difference.
06:29 PM roycroft: i put corn in my chili
06:29 PM roycroft: in the south, tea is sweet and corn bread is not
06:29 PM roycroft: if you put sugar in yours it's yankee corn bread
06:29 PM JT-Cave: starting to sound like brunwick stew now
06:30 PM Tom_L: i'll vouch for the sweet tea...
06:30 PM Tom_L: to me, it's better half and half
06:30 PM roguish[m]: i have a recipe for skillet cornbread. in a cast iron skillet in the over.
06:30 PM roguish[m]: then it's yankee for sure.
06:30 PM JT-Cave: my dad used to make skillet flour bread but I never found the recipe
06:30 PM * roycroft heads out to the electronics bench before he rekindles the civil war
06:31 PM JT-Cave: roguish[m], share it
06:31 PM roguish[m]: i'll find it.
06:31 PM JT-Cave: ok, I'll read back in the pre-dawn hours
06:31 PM roguish[m]: made a batch for thankgiving dinner. came out pretty good.
06:32 PM roguish[m]: key is to preheat the skillet in the oven, then pour in the mix. makes a really crunchy crust.
06:32 PM Alicrow: CaptHindsight[m]: That Leadshine driver looks like what I want, but there's no entry for it on their website and I can't tell where to buy it. Is it discontinued or something?
06:51 PM Alicrow: A Mesa servo driver card sounds pretty good, though. I'm already planning to use a Mesa Anything I/O of some sort, so it should integrate nicely.
06:58 PM CaptHindsight[m]: Alicrow: where are you located? Nearest country
06:59 PM Tom_L: or galaxy...
06:59 PM Alicrow: That 7i29 says it does 22.5 Amps at 165 Volts, though, which is way overkill. Looks like the 7i40H does 80V and 7 Amps, which seems like a better fit (the original electronics, according to the manual, had 7.5 Amp circuit breakers for each servo)
06:59 PM Alicrow: I'm in the US. Northern Virginia/DC area.
07:00 PM roycroft: so you're an i-95 camper :)
07:00 PM CaptHindsight[m]: http://www.leadshine.com/producttypes.aspx?type=products&category=dc-bldc-servos&producttype=brushed-servo-drives their current DC servo selction
07:03 PM Alicrow: Yeah, looks like all of Leadshine's current servo controllers are step+dir.
07:43 PM CaptHindsight[m]: Alicrow: i think I have a bunch of analog in DC servo drives
07:44 PM CaptHindsight[m]: how many do you need? 3, 4?
07:46 PM Alicrow: 3
08:59 PM skunkwor1s: pcw-home: https://photos.app.goo.gl/FYCE9qiwVKiGUaM6A
09:06 PM robin_sz: Evening
09:06 PM robin_sz: So I made first chips on the machine.
09:07 PM robin_sz: https://youtu.be/-E9oYP2rJZE
09:07 PM XXCoder: awesome
09:07 PM robin_sz: nothing crazy, just a series of 2mm doc in aluminium for a pocket.
09:07 PM XXCoder: its making good chips. no powder
09:08 PM robin_sz: yep, I had to slow the spindle down
09:08 PM robin_sz: I'll push it harder as I get used to it
09:09 PM robin_sz: Still need to work on the handwheel issue though, setup was a nightmare
09:10 PM robin_sz: If you want to be really bored, the rest of the blogpost is here: https://g1yfg.blogspot.com/2022/01/a-bit-of-metalwork-for-3cm-dish.html
09:16 PM robin_sz: The machine cut perfectly, as far as I can tell from the DRO, no lost steps
09:28 PM Tom_L: looks good
09:30 PM Tom_L: what size cutter?
09:39 PM robin_sz: 12mm
09:40 PM skunkwor1s: Isn't that an awesome feeling seeing it just do stuff?
09:40 PM robin_sz: yep, always magic
09:41 PM robin_sz: I'm still hoping someone will have a clue about this accel problem with the mpg
09:42 PM robin_sz: https://www.youtube.com/watch?v=PhXRdwXfhvM
09:42 PM Tom_L: Lcvette[m], what pendant do you use?
09:42 PM pcw-home: skunkwor1s the accupin interface? Sort of backwards resolver
09:43 PM Tom_L: robin_sz, Lcvette[m] has a wireless pendant but i can't remember what it was or what driver he used
09:43 PM robin_sz: xhc-hb04
09:44 PM Tom_L: you talk to him about it?
09:44 PM robin_sz: nope, sorry, that's what I have
09:44 PM Tom_L: ok
09:44 PM robin_sz: I have an 06 as well
09:44 PM skunkwor1s: Yes - that is the coil bits. from that it seems to go into a amplified into a square wave. I assumed they just then counted from edge to edge of the input/output.
09:44 PM Tom_L: i knew what you had
09:44 PM robin_sz: maybe we can wake him up ...
09:46 PM skunkwor1s: pcw-home: the main clock was 250khz - the signal to the resolvers was 250hz. SO - if you count the number of cycles - you divide .1 by 1000
09:46 PM skunkwor1s: which was its minimum resolution
09:46 PM Tom_L: skunkwor1s, what you up to now??
09:46 PM robin_sz: Will Mach3 work with a Mesa card?
09:47 PM skunkwor1s: Oh - I have always wanted to get the linear scales working on the K&T
09:47 PM skunkwor1s: GE accupins.
09:47 PM Tom_L: ahh
09:47 PM skunkwor1s: I think an arduino would probably make a decent reader...
09:48 PM skunkwor1s: at 250hz - and 200ipm - you only get 10 read per .1 distance
09:48 PM skunkwor1s: if I did the math right
09:50 PM skunkwor1s: But then I need to learn a bit of arduino.. lol
09:50 PM Tom_L: quadrature code or what?
09:51 PM skunkwor1s: yes - the cheap and dirty option
09:51 PM skunkwor1s: it would basically be a frequency counter
09:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/avr/atmega328/PCINT0/quadrature/
09:52 PM Tom_L: not ardweeny dialect but avr c

09:52 PM skunkwor1s: I probably would understand it better. I have looked at code from the arduino ide - it is confusing.
09:53 PM Tom_L: i've never written anything in arduino speak
09:53 PM Tom_L: this uses interrupts to catch the edges
09:54 PM skunkwor1s: cool - I will take a look.
09:54 PM Tom_L: i have it in xilinx speak as well somewhere if you feel froggy and wanna use a fpga :)
09:55 PM skunkwor1s: between the crappy schematic and the circuit board - I was able to figure out the values

09:56 PM Tom_L: that could use a bath :)
09:56 PM Tom_L: but it might quit if you did
09:57 PM skunkwor1s: lol - it was the bottom row in the control
09:58 PM Tom_L: bud just posted a funny
09:58 PM Tom_L: http://ruemohr.org/~ircjunk/tempimage/google-captvbn.png
09:58 PM Tom_L: had to share that one for sure
09:59 PM Tom_L: skunkwor1s, on that code just change the header for mega328
10:00 PM skunkwor1s: Tom_L: funny!
10:00 PM skunkwor1s: Tom_L: ok - I will take a look - I assume that is some sort of dev board?
10:00 PM Tom_L: which?
10:00 PM Tom_L: the fpga is
10:01 PM Tom_L: just a spartan6
10:01 PM Tom_L: the arduino is pure code for any of the 48...328 series
10:01 PM Tom_L: just maybe a fuse change
10:04 PM Tom_L: it would be wired to the pin change interrupt pins
10:04 PM Tom_L: wherever ardweeny maps them
10:05 PM Rab: <Tom_L> http://ruemohr.org/~ircjunk/tempimage/google-captvbn.png
10:05 PM Rab: That's how you prove you're a robot, right?
10:06 PM Tom_L: uh huh
10:07 PM skunkwor1s: I am color blind
10:08 PM flyback: oh that has to suck
10:09 PM * flyback bites buzzmarshall
10:09 PM flyback: CANUCK
10:09 PM pcw-home: I would expect the excitation to be quadrature, not 180
10:10 PM skunkwor1s: pcw-home: I thought so too - but I don't think so.
10:11 PM skunkwor1s: I think when we played with it in wichita - we figued out they needed to be just out of phase.
10:11 PM skunkwor1s: thy call it 2 phase square wave..
10:11 PM skunkwor1s: they
10:12 PM skunkwor1s: https://electronicsam.com/images/KandT/conversion/accu.pdf
10:13 PM skunkwor1s: You can kinda make out osc and line over osc - for what drives the h-bridges.
10:16 PM pcw-home: 2 phase to me says quadrature
10:17 PM pcw-home: not sure how you get a variable phase output by mixing 0+180
10:19 PM skunkwor1s: well - I hope to test that soon..
10:19 PM skunkwor1s: Almost thought about powering this up..
10:22 PM skunkwor1s: A lot of pins I would have to get right..
10:28 PM Tom_L: skunkwor1s, if you poke around in that avr directory you'll find a couple variations of that quad code
10:29 PM Tom_L: the empty .h files are included to make the compiler happy
