02:25 AM Deejay: moin
02:45 AM gloops: ok some confusion here
02:45 AM gloops: chinese router spindle, 220-240v - i can wire this direct to UK power supply without an inverter right?
02:45 AM gloops: UK mains is 240v
02:46 AM archivist: near enough
02:46 AM gloops: lol
02:46 AM gloops: well advice in here was no - message from china says - 'its 220-240v' which i assume means yes
02:47 AM gloops: but maybe the people on here have different mains in america or europe
02:47 AM archivist: whoever said no was in error
02:47 AM gloops: ok thanks, i think youre right
02:47 AM archivist: big thing is it 3 or 1 phase
02:48 AM gloops: hmm didnt check that assumed single phase
02:48 AM archivist: 3 phase does need an inverter
02:48 AM gloops: yes
02:48 AM archivist: many of the chinesium spindles are 3 phase
02:51 AM gloops: yes it is 3 phase
02:51 AM gloops: see it was worth asking lol
02:51 AM gloops: so it is spindle and inverter
03:14 AM gloops: funny how the build slows right down at the end, all i need now is a spindle and cutters, this thing could have been in work 2 weeks ago, at the beginning i was ordering everything in advance
03:18 AM XXCoder: archivist: including cheap 54mm ones?
03:21 AM archivist: am I supposed to know all "cheap 54mm" always read the data check what the motor is
03:22 AM archivist: a diameter does not specify a model
03:27 AM XXCoder: heh those are all alike
03:27 AM XXCoder: but ok
03:27 AM XXCoder: lemme look
03:28 AM XXCoder: https://www.amazon.com/Spindle-Cooled-Milling-Converter-Engraving/dp/B01LNBOCDA reading now
03:29 AM XXCoder: ot says it has output of 100vdc but does not say if its 3 phase or not
03:30 AM DaViruz: that looks like brushed dc to me
03:30 AM XXCoder: it is, requiring new carbon brushings after certain period. guy here had his expire after 60 hours runtime
03:31 AM archivist: DV is not 3 phase
03:31 AM archivist: DC
03:31 AM XXCoder: aha makes sense. didnt think of that. thanks
03:31 AM DaViruz: that collet chuck looks pretty sketchy
03:31 AM DaViruz: or rather the mounting of it.
03:32 AM XXCoder: DaViruz: it works fine so far, though yeah its not as stright down as it could be. .002" runout?
04:49 AM gloops: if i 0 X i get like -1.112 - not 0
04:52 AM XXCoder: you mean x0?
04:52 AM gloops: yeah if i hit home X the readout for x lands at -1.1 not 0
04:53 AM gloops: it is set at 0 in ini file
04:54 AM XXCoder: the machine home?
04:55 AM gloops: yes, you get the position of xy and z in the right panel - it doesnt read 0 when X is homed
04:55 AM XXCoder: yeah g54 must be not set at machine home, so when it is homed, it is at machine x0, which is not nesscarily g54 x0 for example
04:56 AM gloops: right i understand that - code not using machine home
04:57 AM gloops: will look
04:57 AM XXCoder: okay making sure. not too sure then. so machine coord isnt set to 0 when homed? thats odd
04:58 AM gloops: i understand now you said it - didnt before
04:59 AM gloops: tis strange, would fire stop switch in minus figures if they were connected
04:59 AM gloops: ill check the code anyway, i have been loading random samples and stuff
04:59 AM XXCoder: cool
06:14 AM jthornton: morning
06:15 AM XXCoder: hey
07:08 AM jthornton: I timed the installation of ubuntu server this time and it took 7 minutes from start to finish
07:12 AM XXCoder: reinstallung?
07:13 AM jthornton: yea forgot the samba file server
07:16 AM XXCoder: doh
07:16 AM XXCoder: well time to sleep later
07:17 AM jthornton: goodnight
07:46 AM phipli: afternoon
07:46 AM jthornton: morning
07:47 AM Tom_L: hi
09:32 AM phipli: Anyone built a fitted computer desk lately
09:32 AM phipli: (fitted to the room, although I guess it would be quite poor if it didn't fit the user :) )
09:37 AM Tom_L: my friend built one in his basement similar to kitchen cabinets as an office desk
09:37 AM Tom_L: wrap around 3 walls
09:39 AM phipli: That's the sort of thing that we could do with
09:39 AM Tom_L: the upper doors opened bottom to top and slid inside
09:40 AM Tom_L: http://www.globalindustrial.com/p/storage/partitions/panels/36-overhead-cabinet-charcoal?infoParam.campaignId=T9F&gclid=EAIaIQobChMIwYj71JiJ1gIVlLjACh2uJA4oEAQYAiABEgKgGfD_BwE
09:41 AM Tom_L: something like that
09:41 AM JT-Shop: 4" more on this hole
09:41 AM Tom_L: diggin thru granite?
09:42 AM JT-Shop: seems that way lol
09:42 AM Tom_L: property we had east of here about 3' down you hit rock
09:42 AM Tom_L: needed a jack hammer to break it
09:42 AM phipli: JT-Shop: what shape hole are you digging?
09:43 AM Tom_L: http://mn-fps.com/images/CustomWoodWork/Office/office1d-450x360.jpg
09:44 AM phipli: JT-Shop: I like digging with one of these : https://www.amazon.co.uk/Truper-31609-2-Pound-Mattock-36-Inch/dp/B000KL4UJQ/
09:44 AM phipli: don't know if they're common in the US. Aren't very common here really. Call it a Mattock - cross between a pic and a trench digging tool
09:44 AM Tom_L: yeah i had to use one of those recently on some sprinkler runs
09:44 AM phipli: Excellent tool
09:45 AM Tom_L: 5'D tree n I had a big argument that day
09:45 AM phipli: I also have a hoe that is more like a 90 degree shovel - great for removing lots of earth in one go
09:46 AM phipli: https://www.amazon.co.uk/Garden-Digging-Azada-Wooden-Handle/dp/B00Y10VYNM
09:46 AM phipli: something like that
09:46 AM phipli: mine might be even wider
09:46 AM phipli: https://www.amazon.co.uk/Amtech-A2310-Am-Tech-3lb-Head/dp/B00852NSOU/
09:47 AM phipli: Tom_L: is that second link their office?
09:47 AM Tom_L: no, just a nice setup
09:47 AM Tom_L: it was similar
09:48 AM phipli: I've seen someone use kitchen floor tiles to do the desk surface
09:49 AM phipli: might actually be quite a good idea - as long as you make sure there is a smooth edge between the tiles
09:49 AM Tom_L: laminate would be smoother i think
09:49 AM phipli: I think they did it because laminate was $60 per piece and they needed two...
09:49 AM phipli: kitchen vinyl tiles were 70c each
09:50 AM Tom_L: or use roll vinyl
09:50 AM Tom_L: no seams
09:50 AM phipli: yeah
09:50 AM phipli: I might have a look in the hardware store
09:50 AM phipli: (I'm quite lucky, there is a huge hardware place about 100 yards up the road)
09:50 AM Tom_L: i tend to do everything on the desk so it needs to be durable. ie soldering etc
09:51 AM phipli: exactly
09:51 AM phipli: that was the advantage of the tiles...
09:51 AM phipli: when you burnt a hole, you could replace the one tile :)
09:51 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/scope/scope2.jpg
09:51 AM Tom_L: proof :)
09:52 AM Tom_L: or use ceramic tile but i wouldn't like that
09:53 AM phipli: not recent... but http://elephantandchicken.co.uk/misc/deskshame.jpg
09:54 AM JT-Shop: phipli: I have a mattock but it's no good for post holes
09:54 AM phipli: holes too small diameter?
09:54 AM JT-Shop: 8" in diameter and tapering to 12" and 18" deep
09:54 AM Tom_L: don't have a posthole digger?
09:55 AM JT-Shop: sold it off a years ago
09:55 AM phipli: or explosives?
09:55 AM Tom_L: i know he has those :)
09:55 AM JT-Shop: no room for a tractor anyway
09:55 AM Tom_L: https://www.amazon.com/dp/B005Q7CNRU/ref=asc_df_B005Q7CNRU5152502/?tag=hyprod-20&creative=394997&creativeASIN=B005Q7CNRU&linkCode=df0&hvadid=193142362025&hvpos=1o1&hvnetw=g&hvrand=12893012458398779273&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9024248&hvtargid=pla-313111598856
09:55 AM Tom_L: i meant the hard way
09:56 AM phipli: they look impractical for hard ground?
09:56 AM Tom_L: probably
09:56 AM Tom_L: mine has too many roots for an auger
09:57 AM phipli: JT-Shop: don't you have a cannon... could you mount it vertically and load the post?
09:57 AM phipli: (I'm being helpful :) )
09:57 AM JT-Shop: yea but the poor post...
09:57 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/patio/patio5.jpg
09:58 AM phipli: got practice if you're ever attacked by a vampire army?
09:58 AM Tom_L: when i did the patio, my neighbor brought an industrial auger from his work
09:58 AM Tom_L: and a 12" hole saw
09:58 AM phipli: Tom_L: that took some cutting
09:58 AM phipli: did you keep the cutout as a sun umbrella stand :)
09:58 AM Tom_L: yeah 12" diamond hole drill
09:59 AM phipli: how long did it take?
09:59 AM Tom_L: not that long
09:59 AM Tom_L: there were 5-6 holes i think
09:59 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/patio/patio9.jpg
09:59 AM Tom_L: 5
09:59 AM JT-Shop: I have the following tools for the job
09:59 AM JT-Shop: http://dhtechtools.com/wp-content/uploads/2015/12/s-l160016.jpg
10:00 AM Tom_L: i got lucky, the neighbor works for a road construction company
10:00 AM JT-Shop: http://25wxih3lxatn2okzkn1cr69o.wpengine.netdna-cdn.com/blog/wp-content/uploads/2013/02/20130218_SharpShooter.jpg
10:01 AM Tom_L: i've worn probably 3-4 of those out
10:01 AM Tom_L: break at the top of the steel where the leverage is
10:01 AM JT-Shop: https://static.guillevin.com/media/catalog/product/cache/5/image/9df78eab33525d08d6e5fb8d27136e95/DAM/377/PRODUCT/ae28f0f5-6666-4bc1-a041-05624351113e.jpg
10:01 AM Tom_L: welded a couple and broke them
10:01 AM phipli: Lol, just found this old picture (while getting the desk photo) : http://elephantandchicken.co.uk/misc/CarvingforChristmas.jpg
10:01 AM phipli: my brother preparing to carve the christmas bird
10:02 AM JT-Shop: http://www.forestry-suppliers.com/Images/Original/1991_67237_p1.jpg
10:02 AM Tom_L: JT-Shop, i was looking for that bar but forgot the name
10:02 AM JT-Shop: I call it a pinch bar
10:02 AM JT-Shop: now that's how one carves up a turkey
10:04 AM JT-Shop: so I use the hilti to loosen it up and break big rocks then the sharp shooter to pry rocks up and the post hole digger to remove the debris
10:04 AM Tom_L: the fence gonna be for a chicken yard?
10:04 AM JT-Shop: and if I have a stubborn rock the heavy pinch bar comes into play
10:04 AM JT-Shop: yes, 5' chain link fence around the coop as the inner compound
10:05 AM JT-Shop: got 100' of fence plus the house and florida room as walls
10:05 AM Tom_L: running wire along the base of it?
10:05 AM Tom_L: helps keep it taught for animals crawling under it
10:05 AM JT-Shop: yea the tension wire goes at the bottom
10:05 AM Tom_L: but then they'd just dig under..
10:06 AM JT-Shop: razor wire around the outside bottom... just kidding
10:06 AM phipli: JT-Shop: could you bury a foot of fence at the bottom?
10:06 AM JT-Shop: it's pretty hard digging in rocky clay... wonder how I know
10:06 AM phipli: :)
10:06 AM JT-Shop: not without getting the back hoe out lol
10:07 AM Tom_L: heh, you've moved more than most i know
10:07 AM JT-Shop: dirt?
10:07 AM phipli: our garden is full of builder's waste from when the houses were built
10:07 AM phipli: pain in the neck
10:07 AM Tom_L: yeah at least for residential
10:07 AM phipli: dig a small hole and find a huge paving slab corner
10:07 AM phipli: smash or dig out
10:08 AM JT-Shop: Tom_L: I'm on a dead end dirt road off a dirt road, no residential around here :)
10:08 AM JT-Shop: yea that sucks to find all that crap in your yard
10:08 AM phipli: <envy>
10:08 AM phipli: can't wait to move out of town
10:09 AM phipli: can get goats then
10:09 AM JT-Shop: have you seen Peters sheep?
10:13 AM JT-Shop: one more hole in this run but it going to happen today with 90% humidity and temperatures heading for 87F
10:15 AM phipli: JT-Shop: what is Peters sheep?
10:16 AM phipli: https://www.youtube.com/watch?v=-ZMC4cYTuDo
10:22 AM fdarling: would anyone be able to point me to the source code for the toolpath 3D preview widget in AXIS?
10:23 AM Tom_L: https://github.com/LinuxCNC/linuxcnc
10:23 AM Tom_L: it's in there somewhere
10:24 AM fdarling: Tom_L: I found https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/usr_intf/axis/scripts/axis.py
10:26 AM JT-Shop: pcw_mesa: got a photo of your sheep
10:27 AM JT-Shop: buddy just showed up to change the oil on his goldwing and I had chickens up to my shoulder lol
10:29 AM Tom_L: fdarling that's about as far as my help goes :)
10:30 AM Tom_L: someone in -devel could probably tell you once they wake up
10:33 AM JT-Shop: fdarling: it's gremlin afaik
10:37 AM Tom_L: JT-Shop, do you know of a 'showpins' utility that will list the io and connections to a file?
10:37 AM Tom_L: i had a file here with all the io listed but can't remember how i got it :)
10:37 AM Tom_L: wasn't dmesg
10:37 AM phipli: JT-Shop: did the chick help?
10:38 AM Tom_L: wasn't mesaflash either
10:52 AM JT-Shop: Tom_L: >
10:53 AM Tom_L: right but i don't remember which utility it was i used
10:54 AM JT-Shop: http://www.mesaus.com/info/mesa-pins.txt
10:57 AM Tom_L: instead of loadrt hm2_pci what would parport be?
11:04 AM JT-Shop: http://linuxcnc.org/docs/2.7/html/hal/parallel-port.html
11:06 AM Tom_L: not a parport interface, rather mesa parport driven card
11:07 AM Tom_L: tried running lcnc from cmd line and keep getting errors
11:08 AM Tom_L: not something i do much...
11:08 AM Tom_L: there.. worked that time
11:09 AM Tom_L: must be a typo
11:11 AM Tom_L: finally... thanks
11:34 AM JT-Shop: great
11:47 AM Tom_L: good to keep that list as a last resort backup
01:14 PM Loetmichel: nice. $me can finally exhale... they found a wk2 bomb (1.8 metric tons) while excavating in frankfurt last week.. today at 11:00 they started evacuating a few km around the site... my house is only a km outside the evac zone... just now they announced that it is defused... its 19:45 here now... i was waiting for the big *boom* all day ;)
01:23 PM HighInBC: good to know
01:25 PM HighInBC: so it was dropped in WW2, did not explode, then was forgotten about or not noticed?
01:26 PM Loetmichel: usually they find them when excavating foundations for new houses
01:26 PM Loetmichel: all the time
01:26 PM Loetmichel: IIRC about 2 a day in all of germany
01:26 PM Loetmichel: but not so big ones usually
01:26 PM Loetmichel: and not in so densely populated areas
01:27 PM Loetmichel: the soil there is usually already turned over at least once after the war
01:31 PM gloops: still get the odd one here, think there was a pretty big one this year
01:35 PM Loetmichel: gloops: over here is where?
01:36 PM gloops: UK
01:36 PM Loetmichel: ah
01:36 PM Loetmichel: really? i was under the impression that the germans didnt came close to bombarding the UK, exept for the V2
01:36 PM Loetmichel: and that thing had a LOUSY target accuracy
01:37 PM gloops: the germans were pretty good with UXBs - bombs deliberately designed not to go off on landing, they had highly sophisticated booby trap devices, caused a lot of disruption and tied down highly skilled staff
01:37 PM cpresser: not really. we germans did our share of bombing civilian cities
01:38 PM gloops: Loetmichel the germans bombed london and quite a few other english cities relentlessly
01:40 PM gloops: i asked an old women here if she ever thought the germans were going to win the war, yes! she said, because the bombers kept coming, even when the brits were told we were beating hitler the bombers kept coming over
01:41 PM JT-Shop: Hitler was pissed off when a RAF flight bombed off target and hit a German city so he retaliated by bombing London and thus saving the RAF
01:41 PM gloops: yeah thats how the story goes JT-Shop
01:41 PM Loetmichel: gloops: interesting
01:42 PM Loetmichel: must have missed that in my history lessons
01:42 PM gloops: in my nearest city there was a roundabout built around a massive bomb crater, with a shopping precinct inside it
01:44 PM gloops: http://www.sheffieldhistory.co.uk/forums/uploads/monthly_02_2007/post-1-1171236489.jpg
01:44 PM Loetmichel: funny
01:46 PM Loetmichel: but honestly: how could i have not known that the germans DID bomb the uk? i really thought the V2 werer the only bombs that fell on london
01:46 PM gloops: well it is now, it was different back in the day
01:46 PM Loetmichel: i think i should talk a stern word with my history teacher
01:46 PM gloops: hitler just accross the channel waiting to punce
01:46 PM gloops: pounce
01:47 PM CaptHindsight: Hitler was Austrian, never trust the Austrians!
01:47 PM Loetmichel: THAT i know ;)
01:47 PM gloops: maybe, but he would say austria is part of germany haha
01:49 PM CaptHindsight: and Patton was right, we should have just just kept going east :)
01:49 PM CaptHindsight: anyone watch The Man in the High Castle?
01:50 PM CaptHindsight: fiction alternate history
01:51 PM cpresser: its on my 'watchlist'
01:51 PM CaptHindsight: it's very well done about the Axis winning WWII
01:53 PM hazzy1 is now known as hazzy
01:53 PM gloops: not seen that Capt, will keep an eye out for it
01:53 PM gloops: one thing is for sure, if the yanks hadnt nuked japan, Stalin would have kept driving west
01:54 PM CaptHindsight: Stalin wasn't any better
01:55 PM CaptHindsight: 100 years of mess in that country since their revolution
01:56 PM cpresser: nobody did anything nice during that time. $me is really glad this whole war-thing is finally over for europe.
01:58 PM gloops: lol, i wouldnt bank on that cpresser
01:59 PM CaptHindsight: Austrian Navy is set to invade :)
02:01 PM gloops: brexit, immigrant crisis, banking crisis, east european rebelling to the right, all kinds of trouble brewing
02:03 PM * JT-Shop needs to machine some parts but the noise bothers the chicks so a moving blanket over the RPC and one around the compressor and some soothing talk when the compressor starts seems to work
02:05 PM HighInBC: more chicks, more problems
02:06 PM CaptHindsight: kids adapt
02:07 PM CaptHindsight: and they might be starting to train you
02:08 PM JT-Shop: aye I'm trained to take care of them and sit still while the crawl all over me
03:49 PM phipli: Loetmichel: doesn't quite compare to Dresden, but this happened : https://en.wikipedia.org/wiki/Coventry_Blitz
03:50 PM Loetmichel: Interesting. seems i missed quite a lot in history class
03:52 PM phipli: And this is why we keep an eye on our governments
03:52 PM phipli: left to their own devices they love doing that sort of thing
03:56 PM Wolf__: nice, the mystery lathe is no longer a unknown… Enco DSL-1237GH.. but missing the threading lead screw, 3 change gears and thread dial =/
04:12 PM phipli: New lathe Wolf__ ?
04:13 PM Wolf__: https://i.imgur.com/WjcmWDV.jpg Buying out old friends fathers home shop
04:14 PM Wolf__: comes with some tooling =) https://i.imgur.com/tGEs5nW.jpg
04:15 PM phipli: got it home yet?
04:16 PM Wolf__: no, I won’t have time to move it till end of october
04:17 PM Wolf__: deal is already set, right now I have the manuals for the mill and lathe sitting here on my desk
04:17 PM Wolf__: odd as hell, says 7/8
04:17 PM Wolf__: lead screw with 8 tip
04:18 PM Wolf__: t.p.i
04:33 PM phipli: you're in the US?
04:33 PM Wolf__: yup
04:33 PM Wolf__: near DC
04:33 PM Wolf__: Baltimore area
04:40 PM JT-Shop: phi
04:41 PM JT-Shop: phipli: just had one walk up my arm across my shoulder and sat there for a while the flew up to the top of the brooder
04:42 PM Cromaglious_: Just bought $175 worth of Starrett parallels, adjustable Parallels, and 4 123 blocks, and maybe some gauge pins.
04:43 PM MarcelineVQ: after watching a lot of vids parallels seem endlessly handy for any manual work
04:44 PM Cromaglious_: even for CNC work
04:44 PM Wolf__: the adjustable are very handy
04:46 PM Wolf__: hmmm
04:47 PM Wolf__: looks like I might be able to order a lead screw for a grizzly 4003 for this 1980’s enco lathe lol
04:47 PM Cromaglious_: I have some Ryobi brussless, hammer drill, a drill, and a 1/4" impact driller coming. Bought them on Amazon.
04:48 PM Wolf__: I just bought a whole shop...
04:48 PM Wolf__: Mill, lathe, drill press, bandsaw, 3 grinders, giant load of tooling and raw stock
04:51 PM Wolf__: ouch, $210 for a damn lead screw
04:52 PM MarcelineVQ: yeah they're not cheap, if you have a good mill you could work towards cutting your own though
04:52 PM MarcelineVQ: *lathe
04:53 PM Wolf__: kinda hard to cut a thread on the lathe when the lathe is missing the threading lead screw...
04:54 PM Wolf__: actually looks like the G0750G uses the screw that I’m missing, 7/8” 8tpi
04:56 PM Wolf__: and better price, $170.25
05:01 PM Wolf__: anyone here running a G0750G lathe?
05:07 PM Deejay: gn8
05:08 PM Cromaglious_: Wolf__, not I
05:08 PM Cromaglious_: Acme?
05:08 PM phipli: JT-Shop: how long before you move them out of the brooder?
05:09 PM Wolf__: yeah, the guy I’m getting the stuff from never did any threading work on the lathe so he took the carriage lead off…
05:09 PM Cromaglious_: cnc it! hehe...
05:09 PM Wolf__: I would, but I’m planning on using it for gunsmithing so everything is one off
05:10 PM sync: just use the mdi
05:11 PM Wolf__: I guess I could go that route
05:12 PM Cromaglious_: hmm seeing 7/8-6 acme 7/8-5 7/8-4, not seeing 7/8-8
05:13 PM Cromaglious_: oh jeeze.. I'd never use this http://www.ebay.com/itm/Vintage-Cast-Iron-Acme-Trailer-Hitch-Receiver-No-210-1-7-8-Ball-/192294605960
05:13 PM Wolf__: yeah its a odd ball
05:15 PM Wolf__: G0750G uses a 7/8 8tpi 46.75” long carriage leadscrew
05:17 PM roycroft: 8tpi is pretty common for a lead screw pitch
05:18 PM Wolf__: I’ll have to get some measurements off the DSL-1237GH then find a grizzly users group and see if someone can check some measurements off their machine
05:19 PM roycroft: iirc there's a grizzly gunsmith's lathe group on google groups
05:20 PM Wolf__: that and post on the linux cnc forums, I bet there have been a few of this converted lol
05:20 PM roycroft: or maybe it's a yahoo group
05:20 PM Wolf__: maybe find someones leftover parts
05:20 PM roycroft: my lathe lead screw is 8tpi, and it's about 7/8" in diameter
05:20 PM roycroft: i haven't measured it though
05:21 PM roycroft: it's a jet with a frankenstein spindle thread (60mm x8tpi)
05:21 PM Wolf__: I have the manual, its specs 22mm/ 7/8” 8tpi
05:21 PM roycroft: maybe it has a frankenstein lead screw as well, like 22mm/9tpi
05:21 PM roycroft: er 8tpi
05:22 PM roycroft: 8tpi makes gearing for thread cutting simple
05:22 PM Wolf__: this one is a ENCO/ Dar Sin (Taiwan)
05:22 PM roycroft: and it makes 1 revolution move the carriage 0.125", which works decently
05:23 PM roycroft: 10tpi is nicer in a way, because one rev is 0.100", but it makes gearing for threading a bit more complicated
05:23 PM Wolf__: I’m also missing 3 of the change gears :(
05:23 PM Wolf__: https://i.imgur.com/33AWLh1.jpg
05:35 PM roycroft: change gears for that should be easy to find, if you really need them
05:35 PM roycroft: if you have two 40 tooth gears and the 120 and 127, you're set for almost any thread pitches you need to cut
05:36 PM andypugh: Excel is great for working out change-gears.
05:36 PM Wolf__: yeah, just matter of figuring out what current taiwan machines match the shaft size
05:36 PM JT-Shop: phipli: another week or so
05:36 PM andypugh: But, CNC is better ;-)
05:36 PM XXCoder: hey andypugh
05:37 PM Wolf__: I am tempted but I need working machine sooner then later
05:37 PM andypugh: My Chinese lathe had a quick-change gearbox, but the gears were chosen by a lunatic. Even changing from 1.0 pitch to 1.25 pitch meant changing the QC gearbox _and_ the pick-off gears.
05:39 PM Wolf__: lol
05:39 PM XXCoder: doh
05:40 PM Wolf__: I’m not even sure which gears are in this one, the 120/127 are in it, didn’t pull the top and bottom gears to see what they were
05:41 PM andypugh: Is it a metric or an imperial lathe, and which type of thread do you want to cut?
05:41 PM Wolf__: https://i.imgur.com/33AWLh1.jpg
05:43 PM roycroft: if they look to be the same size they're likely both 40 tooth
05:43 PM Wolf__: I would rather have full range
05:43 PM roycroft: and i'd bet that's what is on there
05:44 PM Wolf__: we haven’t dug through everything there, he was pretty sure he had put all the parts that he wasn’t using in his garage but didn’t find the lead screw or gears out there =/
05:45 PM Wolf__: I bet its in a box in the back of a cabinet somewhere lol
05:45 PM Wolf__: or hope so anyways
05:45 PM roycroft: so there's a chance you can still get the stuff from the seller?
05:45 PM andypugh: What is the leadscrew pitch?
05:45 PM roycroft: 8tpi
05:46 PM Wolf__: 7/8” 8 tpi, I already found a possible replacement via Grizzly
05:46 PM andypugh: OK, no point me sending you my 1.5mm pitch table for the Chinese lathe then
05:46 PM andypugh: An electronic leadscrew with an arduino and a stepper might still be a good solutiuon.
05:47 PM Wolf__: roycroft: I haven’t moved anything yet, just set the deal up so far, have the manuals for the lathe and mill here though
05:48 PM gloops: quite a few lathes in america get posted on facebook group 'home machine shop'
05:49 PM gloops: http://bilar.co.uk/cgi-bin/change-gear-calculator.pl
05:50 PM gloops: loads of these little calculator scripts online, you can input the gears you have and it works out closest setup
05:50 PM Wolf__: heh, yeah, even easier to use the chart on the machine…
05:51 PM gloops: if it has one
05:51 PM Wolf__: last omg link I posted
05:51 PM Wolf__: s/omg/img
05:52 PM XXCoder: hey gloops solved that coord issue?
05:52 PM gloops: lot of old ones have nothing, mine doesnt
05:52 PM roycroft: i'd tell the seller to find the lead screw before you will pay for it
05:52 PM roycroft: the missing change gears aren't that big of a deal, although it would be nice to have them
05:52 PM gloops: XXcoder no didnt end up looking at it got into something else, will have a look later in the week now
05:52 PM roycroft: but the lead screw is essential
05:52 PM XXCoder: lol ok
05:53 PM Wolf__: roycroft: I’m buying out his whole shop, mill/lathe/drill press, and well over $10k in tooling
05:53 PM roycroft: and is big enough that the seller should be able to find it
05:54 PM Wolf__: https://i.imgur.com/tGEs5nW.jpg https://i.imgur.com/LxiIeKA.jpg
05:54 PM Wolf__: thats just the quick glimpse in to what I’m getting lol
05:55 PM andypugh: The chart on the machine shows one gear setup for each thread. In practice most threads can be made with many different combinations. A complete table for your machine can avoid unnecessary swaps, and might let you make threads that you don’t think you have the gears for.
05:56 PM Wolf__: missing leadscrew is a big deal for the machine, but not really when it comes to the overall deal
05:56 PM andypugh: I am just wonderng how you lose a leadscrew.
05:57 PM andypugh: I have a spare one for a Holbrook Minor (and that’s probably a _very_ good leadscrew,
05:57 PM Wolf__: no idea lol, I think he got the machine new in 80’s and never did threading so he took it off and put a makeshift carriage stop in its place
05:57 PM andypugh: Is it a single-shaft lathe?
05:58 PM Wolf__: https://i.imgur.com/WjcmWDV.jpg
05:58 PM Wolf__: 2, lead screw + feed shaft
05:58 PM andypugh: OK, he is actualy insane.
05:58 PM Wolf__: all the parts he made were small, no threading lol
05:59 PM Wolf__: odd prototyping and electron microscope parts
05:59 PM andypugh: But taking it off?
05:59 PM Wolf__: yeah idk on that lol
06:00 PM Wolf__: it worked for him for 30+ years
06:00 PM Wolf__: I can’t really complain seeing that all the machines are still like new tight
06:01 PM andypugh: Everything looks a lot more shiny than I am used to. Dry climate?
06:01 PM Wolf__: home basement
06:01 PM andypugh: http://littlemachineshop.com/products/product_view.php?ProductID=5097&category= any use?
06:01 PM XXCoder: seems to me to be very highly maintanced machine andypugh
06:01 PM Wolf__: and well maintained
06:02 PM Wolf__: too short, this is a 1237 lathe
06:02 PM andypugh: I am actually painting my miling machine at the moment! (I am as surprised as you)
06:02 PM Wolf__: so should be 46”ish length
06:04 PM Wolf__: knobs on this thing look the same as the jesco made Jet lathes so i’m hoping there is part interchange
06:04 PM andypugh: Plan is to take it back to the original dark grey. https://photos.app.goo.gl/WCePJgLrxhETH4T92
06:04 PM Wolf__: nice
06:05 PM andypugh: Mainy because the pale grey put on before I bought it isn’t coolant-proof :-)
06:05 PM Wolf__: doh lol
06:06 PM andypugh: The red is knifing putty, like a flller that you don’t have to mix. Great stuff.
06:06 PM Tom_L: laquer based or epoxy?
06:06 PM andypugh: I think they use it for scratch-repair on cars.
06:06 PM Tom_L: yep
06:06 PM andypugh: It’s basically a very thick version of paint.
06:06 PM Wolf__: I’ll be back over there thursday so I’ll get to poke at the machines a bit more, need to trouble shoot the power feed on the mill as well
06:06 PM Tom_L: right
06:07 PM Tom_L: i used to have a tube of it
06:07 PM Wolf__: I think the 220-110 transformer in the control box is dead
06:14 PM JT-Shop: does it smell dead?
06:16 PM Wolf__: no didn’t stick my nose in it, but the machine light and pilot light for power are dead (on 110 out on the transformer) and the power feed is controlled off the limit switches on 110 rail
06:16 PM Wolf__: I didn’t have a DMM to check anything
06:17 PM Wolf__: power feed did work when I pushed the contractors closed tho
06:19 PM JT-Shop: usually a transformer smells bad when it has a melt down
06:19 PM Wolf__: no idea, might be something stupid as well, only way to know is checking things with DMM
06:20 PM JT-Shop: or a lamp
06:21 PM Wolf__: yeah, 110 lights don’t like 220 tho
06:21 PM JT-Shop: use 2
06:22 PM Wolf__: lol
06:22 PM JT-Shop: really 1 leg is only 120v to ground
06:23 PM Wolf__: its a 220 3 phase machine
06:24 PM Wolf__: that 110 on each leg?
06:25 PM JT-Shop: yup
06:25 PM JT-Shop: 2 120 legs is 240...
06:25 PM JT-Shop: now where are my 3.3v relays
06:26 PM Wolf__: https://i.imgur.com/Z7nYQld.jpg
06:26 PM Wolf__: yay for having the manual…
06:36 PM JT-Shop: oh crap I forgot to bill for a job last week
06:47 PM XXCoder: doh
06:47 PM XXCoder: does it mean they got it for free? lol
07:03 PM JT-Shop: no
07:03 PM Tom_L: for a week they did
07:03 PM Tom_L: JT-Shop what brand ssd was that you got?
07:04 PM Tom_L: looking at that board a bit..
07:04 PM Tom_L: oh wait, i found it
07:04 PM Tom_L: WD
07:04 PM XXCoder: lol

07:17 PM Wolf__: any suggestions for where to shop DRO for mill and lathe ? other then cnc conversion =P
07:18 PM Tom_L: travers
07:20 PM Tom_L: https://www.travers.com/standard-dro-packages-counter-scales/p/35101/?keyword=dro&lite=true&pricelistname=SITE
07:20 PM enleth: today's story: in Polish, the word for "inert" as in "inert gas" is the same as the word for "any" or "whichever" as in "any one out of many" - so this guy was learning to TIG weld and it wasn't any good so he asked a coworker for advice and it was immediately obvious he used CO2 instead of Argon. "did you read the manual?" - "sure, it said 'use [inert/any] shielding gas', so I got whatever" - and the
07:21 PM enleth: whole shop sighed with relief that he didn't choose acetylene
07:21 PM Tom_L: https://www.travers.com/innova-series-dro/p/57-012-717/
07:22 PM sync: nice enleth
07:25 PM Wolf__: description leaves a lot to be desired on Travers
07:25 PM Wolf__: $795 for what? just the box or what
07:34 PM Tom_L: dunno but that's supposed to be a good brand
07:34 PM Tom_L: i'd call em
07:36 PM Tom_L: http://www.fagorautomation.com/downloads/manuales/en/man_dro_i_m.pdf
07:37 PM andypugh: Wolf__: I guess you are in the US? With our new super-weak pound: https://www.machine-dro.co.uk
07:37 PM Tom_L: http://www.wttool.com/index/page/static/subpage/fagor
07:38 PM Tom_L: Kit Includes: 2x High Performance Scales, Armored Cables, Mounting Hardware, & Mounting Arm
07:41 PM Tom_L: apparently they come with glass scales
07:42 PM Tom_L: or not so apparently..
07:45 PM MarcelineVQ: enleth: scary
07:45 PM Wolf__: seeing these are all made in china I could always just ali a set
08:00 PM Vitran: Ug..... I finished rewiring the 7i77 and 7i64 with a new wiring layout, finished updating the software, put it in and plugged it in. I wired 24VDC to the two 5VDC inputs for the 7i77 and 7i64. Soooo unhappy atm
08:01 PM Vitran: Don't know why I thought the boards ran off of 24VDC
08:02 PM kb8wmc: I am having a time making a wiring connection on 7i76...just plain lost I guess
08:03 PM kb8wmc: first time using Mesa boards
08:03 PM Vitran: It makes a lot more sense after a few hours
08:03 PM kb8wmc: I can test motor, but am at a loss on connecting in a limit/home switch
08:04 PM Wolf__: use wires...
08:04 PM kb8wmc: I sure hope it does make more sense
08:04 PM Vitran: What the I/O does are in the .hal files
08:04 PM Vitran: or in the configuration tool
08:04 PM kb8wmc: Wolf__: what a novel idea...lol
08:04 PM Wolf__: =)
08:05 PM Vitran: But I think I completly fried my boards
08:05 PM Vitran: Yay. Money gone!
08:05 PM Vitran: No smoke though
08:05 PM Wolf__: only gets weird imo if you are using powered sensors/switches
08:05 PM Wolf__: as for the cooked boards, may want to ask pcw_mesa what you might have cooked doing that
08:06 PM kb8wmc: I am attempting to wire the switches in series, I have power to a single switch for testing right now,but just where to connect to the TB6 board, is a mystery
08:07 PM Vitran: What pin did you set to be the limit switch?
08:08 PM kb8wmc: that is the question I have myself...how to choose the pin
08:08 PM Vitran: Do you have Linux CNC open?
08:08 PM kb8wmc: yes
08:09 PM Vitran: When you did the configuration tool, you set one pin to be the limit switch
08:09 PM Vitran: Well, look on page 3 of the 7i76 manual.
08:09 PM kb8wmc: rgr, stand by will take a look
08:09 PM Vitran: It has TB5 0-16
08:09 PM Vitran: Those are the standard inputs that you programmed in the configuration tool
08:10 PM Wolf__: rtfm… weird
08:10 PM Vitran: Yeah, maybe at this point rtfm
08:11 PM kb8wmc: I have been reading the 7i76/5i25 manuals for the last 3 weeks...
08:11 PM kb8wmc: it is my lack of comprehension that is the problem...
08:12 PM kb8wmc: done lots of searching also in the forum
08:13 PM kb8wmc: right now I have the NC limit switch connected to pin 5 on the TB
08:15 PM kb8wmc: and getting its power from terminal 2 on TB1 (Field pwr)
08:17 PM kb8wmc: I have power through the switch, but when testing the homing upon activating the switch it is not working
08:20 PM Vitran: The field power is for outputs. The limit switch is connected to your 24VDC power supply with the other lead going to the TB-5
08:25 PM kb8wmc: does that mean I am not able to pull 24V power for the limit switch from the TB1 field power?
08:26 PM Tom_L: Vitran, good with a soldering iron?
08:26 PM kb8wmc: and, am I not able to use TB6 instead of TB5?
08:26 PM kb8wmc: yes, I can use a soldering iron, but what for?
08:27 PM Tom_L: are you Vitran?
08:27 PM Tom_L: he cooked his 5v it sounds like..
08:28 PM Tom_L: 7i76 is a stepper board right?
08:28 PM kb8wmc: yes
08:28 PM kb8wmc: it functions with steppers
08:30 PM Tom_L: what are you trying to do?
08:31 PM kb8wmc: complete a plasma table for my brother, we are at the wiring stage
08:32 PM Tom_L: using 24v field voltage?
08:32 PM kb8wmc: that is the power supply we have
08:36 PM Tom_L: for the IO to pin connections i made a chart to associate them
08:36 PM Tom_L: makes it a little easier
08:36 PM kb8wmc: aha
08:37 PM Tom_L: i've changed my configuration a few times due to upgrades etc
08:37 PM kb8wmc: very good
08:37 PM Tom_L: if you want to know the special pin IO like step, direction you can use mesaflash to list that
08:38 PM Tom_L: dmesg will give you information too
08:38 PM kb8wmc: I have done that
08:38 PM Tom_L: the 5i25 is pci right?
08:38 PM kb8wmc: I have one motor working for test purposes
08:38 PM kb8wmc: correct tom
08:39 PM Tom_L: what are you confused on?
08:39 PM Tom_L: i don't have that combination of boards but they are similar i'm sure
08:40 PM kb8wmc: I have a limit switch for testing purposes, I have two wires on it, one on common which runs to field power pin 2, and other on NC running to pin 5 on TB6
08:41 PM Tom_L: do you have mesaflash utility?
08:41 PM kb8wmc: when during test I activate the homing, it is as if the switch is not there,
08:41 PM kb8wmc: yes I have mesa flash
08:43 PM Tom_L: that's IO 4 it appears
08:43 PM kb8wmc: correct
08:43 PM Tom_L: but i'm not sure what IO it is on the 5i25
08:43 PM kb8wmc: hang on will open the manual file
08:44 PM Tom_L: ok, P10 on the 7i76 gives that
08:46 PM kb8wmc: I can't find the file
08:46 PM Tom_L: mesanet.com has it
08:47 PM kb8wmc: rgr..., I found it
08:47 PM Tom_shop: sudo ./mesaflash --device 5i25 --pci --readhmid
08:47 PM Tom_shop: will list the pin functions
08:48 PM Tom_shop: or show GPIO
08:49 PM kb8wmc: yes,...it was factory flashed already for the 7i76
08:49 PM Tom_L: in hal show configuration you can view the state of the input and watch it change state with the switch
08:49 PM Tom_L: from the axis menu
08:50 PM kb8wmc: right, no change is occuring
08:50 PM Tom_L: maybe it's active low?
08:50 PM kb8wmc: hmmm, don't know about that
08:52 PM kb8wmc: as I mentioned the switch is setup to operate in NC mode, and when I manually trip it it shows on my multimeter as working properly
08:52 PM Tom_L: and the other end of the switch goes to 24v
08:53 PM Tom_L: can you view that GPIO pin in hal show config?
08:55 PM kb8wmc: will see, standby
08:55 PM Vitran_: I went home, so I am back at another computer
08:55 PM Tom_itx: Inputs are sinking type. That is they sense positive input
08:55 PM Tom_itx: voltages relative to field ground.
08:59 PM kb8wmc: I am beginning to think that the problem lies in my .hal file configuration
08:59 PM Tom_L: i wonder if you need a pullup to field to the pin and run the NC pin to field GND
09:00 PM Tom_L: are you sure that's GPIO 4?
09:00 PM Tom_L: in the hal you can invert the signal
09:00 PM kb8wmc: I can easily and quickly check the pin to field ground...
09:00 PM Tom_L: use resistors until you are sure about yourself
09:01 PM Tom_L: it should be ok though
09:01 PM Tom_L: bring up hal show config and view the io as you do
09:03 PM kb8wmc: that did not do it....I will have to wait till tomorrow when I go out to shop and pick up some different values of resistors
09:03 PM Tom_L: i'm fairly sure you can just use a wire
09:03 PM Tom_itx: The 7I76 field inputs have a nominal input resistance of 10K Ohms to field power
09:03 PM Tom_itx: ground. 7I76 inputs sense positive input voltages above a preset threshold.
09:04 PM kb8wmc: okay, tnx for that info
09:04 PM Tom_L: it's in the manual :)
09:05 PM kb8wmc: I have been at a loss with this thing...I have read manuals till my old eyes water...
09:05 PM Tom_L: first time can be a bit challenging
09:05 PM Tom_L: ask questions and stick with it
09:06 PM Tom_L: if you have a NC switch connected to 24v, you may need to invert the signal in hal
09:06 PM kb8wmc: I have build almost a dozen other types of cnc machines over the years, but this is the first time using Mesa boards...
09:06 PM Tom_L: they are top notch
09:07 PM Tom_itx: 7I76 field inputs are of the sinking type. That is, external power must be applied to
09:07 PM Tom_itx: the input to register as activated. This mode was chosen so that accidental grounding of
09:07 PM Tom_itx: an input will not register as an activated input.
09:08 PM kb8wmc: after reading regarding their capabilities the certainly seem to be top notch, I am afraid it is not the Mesa boards that are at fault here, it is me..
09:09 PM Tom_L: what's the hal file look like for that pin?
09:11 PM kb8wmc: presently from my hal the pertinent parts are:
09:12 PM kb8wmc: net all-home => axis.0.home-sw-in
09:13 PM Tom_shop: ok, all-home is a net there not a signal
09:14 PM kb8wmc: right, networking function
09:14 PM Tom_L: you would be looking for a GPIO in from a hm2_xxxx.00.something pin
09:15 PM kb8wmc: the following line was tried and unsuccessful:
09:15 PM Tom_L: dmesg will give you the syntax for that
09:16 PM kb8wmc: net home-x <= hm2_6i25.0.7i76.0.0.input-04
09:16 PM Tom_shop: there may be an extra .0 there, i'm not sure how your board is addressed
09:17 PM kb8wmc: sorry, the 6i should read 5i25
09:17 PM Tom_shop: that's fine
09:17 PM Tom_shop: [ 7362.001690] hm2/hm2_7i90.0: IO Pin 027 (P2-07): IOPort
09:17 PM Tom_shop: is what dmesg shows for mine
09:17 PM kb8wmc: it shows two zeros
09:17 PM Tom_shop: that's fine
09:18 PM Tom_shop: use 2 then
09:18 PM Tom_shop: is there a '.' between them?
09:18 PM kb8wmc: ys
09:18 PM kb8wmc: yes, period
09:20 PM Tom_shop: that line looks ok
09:20 PM Tom_shop: but i'm not real familiar with that board combination
09:21 PM kb8wmc: neither am I familiar with it...lol
09:21 PM kb8wmc: I sure do appreciate your time and input though
09:21 PM Tom_shop: hm2_[HOSTMOT2](BOARD).0.7i84.0.0.input-13
09:21 PM Tom_shop: similar to that
09:23 PM kb8wmc: looking
09:23 PM Tom_shop: tip: in your ini you can define your board and then address it like i did there
09:24 PM kb8wmc: I have already done that...
09:24 PM Tom_shop: [HOSTMOT2]
09:24 PM Tom_shop: ##DRIVER=hm2_7i43
09:24 PM Tom_shop: ##BOARD=7i43
09:24 PM Tom_shop: for example
09:24 PM kb8wmc: I moved it to the top of the ini
09:24 PM kb8wmc: placeholders
09:25 PM Tom_shop: somebody will help tomorrow i'm sure
09:25 PM Tom_shop: it's just one little thing you're missing
09:25 PM kb8wmc: roger that tom...I hope that is the case
09:26 PM Tom_L: then you'll be off and running to the next hurdle
09:26 PM Tom_L: take good notes
09:26 PM kb8wmc: I am sure there are plenty of folks that can look at it and quickly point me in the proper direction
09:26 PM Tom_L: you will appreciate it later
09:27 PM kb8wmc: lol...yeah I have books of notes over the years
09:27 PM kb8wmc: old school learning real slow
09:27 PM Tom_L: i think it's IO is similar to my 7i84 but i haven't had it out in a long time
09:28 PM Tom_L: so i don't want to give bad advise
09:28 PM Tom_L: i used 5v field power on it iirc though
09:28 PM kb8wmc: I rather lean to it is something I am not doing correctly or have done incorrectly or not at all
09:29 PM kb8wmc: and if I did it, I probably won
09:29 PM Tom_L: you should be able to see activity on it in hal show configuration though
09:29 PM kb8wmc: t be able to find it
09:29 PM Tom_L: unless you have the wrong IO or something
09:29 PM kb8wmc: I would think the same, but alas not so
09:29 PM Tom_L: why did you choose IO 4?
09:30 PM Tom_L: wait... IO 4 is DIR2 output on P1 connector
09:30 PM kb8wmc: I took a look at a schematic put together by the man who developed gmoccapy
09:30 PM kb8wmc: it is on the forums in the driver category
09:31 PM kb8wmc: the schematic indicated to commence using pins on TB6 starting at 004 as the previous pins were analog
09:32 PM Tom_L: one sec
09:32 PM kb8wmc: and starting at 04 were the three limit switches
09:34 PM Tom_shop: if it truly is GPIO 4 you can't use it
09:34 PM Tom_shop: input 4 doesn't map to GPIO 4
09:34 PM Tom_shop: you need to find what GPIO it is
09:35 PM kb8wmc: hmmm...
09:35 PM Tom_shop: GPIO 4 is DIR pin for Z i believe
09:35 PM Tom_shop: i'm looking at the bit file for the card
09:35 PM kb8wmc: let me find the pdf schematic file that he did
09:36 PM Tom_shop: starting with GPIO 17 the pins are open
09:36 PM Tom_shop: is this on the external DB25 connector?
09:38 PM Tom_shop: the 26pin header is all open to GPIO afik
09:38 PM kb8wmc: the name of the file is 7176_Anschluss.pdf....sorry, I cant find the page to link to you
09:38 PM Tom_shop: it's ok, i'm using docs from mesa
09:38 PM kb8wmc: oh, okay
09:39 PM Tom_shop: is this all connected to the external DB25
09:39 PM kb8wmc: my db25 only connects to the 5i25 and 7i76
09:39 PM Tom_shop: yes
09:40 PM Tom_shop: do you have anything to connect to the internal 26 pin header?
09:40 PM kb8wmc: I have nothing on the 5i25 26 pin connector
09:40 PM Tom_L: lemme think about this ..
09:43 PM Tom_L: no, it should work as you have it
09:43 PM Tom_L: but you need to figure out what GPIO input 4 is on
09:43 PM kb8wmc: https://forum.linuxcnc.org/media/kunena/attachments/3278/7i76_Anschluss.pdf
09:43 PM kb8wmc: the above link is the schematic I have following as best I can
09:43 PM Tom_L: got it
09:45 PM Tom_L: that example is using an 7i76e ethernet card
09:45 PM Tom_L: don't try to use that for your setup it's different
09:46 PM kb8wmc: yes it is, but somewhere I read that the boards are the same with obvious differences
09:46 PM kb8wmc: that being in the communications portion
09:47 PM kb8wmc: that is as I understood it only
09:47 PM Tom_L: can you post your dmesg file
09:48 PM kb8wmc: it would be on the test computer, not this one and would take me some time
09:48 PM Tom_L: ok
09:48 PM Tom_L: that will give us a clue though
09:48 PM Tom_L: do: dmesg -c then run linuxcnc and dmesg > dmesg.txt or such
09:49 PM kb8wmc: right, it may have to wait till tomorrow,
09:49 PM Tom_L: that will give us only what we want to see
09:49 PM Tom_L: that's fine
09:49 PM kb8wmc: yes sir...that be the command code
09:50 PM Tom_L: actually the IO part of those cards do look similar
09:52 PM Tom_L: he did a nice job on that pdf
09:53 PM kb8wmc: yes he did, it is a keeper
09:54 PM kb8wmc: hey, I just run a dmesg as follows: .plasma.hal:115: Pin 'hm2_5i25.0.7i76.0.0.input-04' does not exist
09:55 PM kb8wmc: what ya think about that?
09:55 PM Tom_L: heh
09:56 PM Tom_L: syntax error in the hal maybe?
09:59 PM kb8wmc: what ever it may be, I am sure I at the root of it
10:06 PM Tom_L: yeah
10:11 PM Tom_L: what mode is the 7i76 set for?
10:11 PM Tom_L: P. 18
10:11 PM kb8wmc: as I remember it is mode 0
10:18 PM Tom_L: ok i'm guessing the onboard io goes thru an onboard sserial link
10:18 PM Tom_L: which comes out on IO 10-11 or IO 11 12 on the DB25
10:19 PM Tom_L: just guessing...
10:20 PM Tom_L: one of those pair shows up on TB3 pins 16-19
10:20 PM Tom_L: probably SS1
10:21 PM kb8wmc: hmmmm....
10:21 PM Tom_L: the SS0 would drive the onboard IO i think
10:21 PM Tom_L: doesn't fix your problem, just trying to understand what's happening
10:22 PM kb8wmc: are you then thinking that the 7176 is considered to be Smartserial by the 5i25
10:22 PM Tom_L: i don't want to say for sure but it may be
10:22 PM kb8wmc: cuz, I have no other boards after the 7i76
10:22 PM Tom_L: at least parts of it
10:23 PM Tom_L: i know
10:23 PM kb8wmc: ok....
10:23 PM Tom_L: look at the DB25 pinout
10:23 PM kb8wmc: yeah
10:23 PM Tom_L: some of it goes directly to step, direction etc
10:23 PM Tom_L: and encoder
10:23 PM Tom_L: but there are 2 sserial there too
10:24 PM Tom_L: i'm betting he gives you one for further expansion and uses one on board
10:25 PM kb8wmc: the two SS use 4 pins 3 for transmit and 2 for receive
10:25 PM Tom_L: yes
10:25 PM Tom_L: huh?
10:26 PM Tom_L: SS0TX SS0RX SS1TX SS1RX
10:26 PM kb8wmc: TX RX
10:26 PM Tom_L: that should be it
10:26 PM Tom_L: on the db25
10:26 PM kb8wmc: right
10:26 PM Tom_L: ^^ 3 typo
10:27 PM Tom_L: then the differential pairs show up on TB3 16-19
10:27 PM Tom_L: probably SS1
10:28 PM kb8wmc: I have found that both the TB2 and TB3 are really not configurable as they are sort of permanently hard coded to do the step/direction functions as well as encode
10:28 PM Tom_L: this isn't gonna help with the wiring, just undestanding how it's put together
10:28 PM kb8wmc: yes
10:28 PM Tom_L: that's all set in the bitfile
10:28 PM Tom_L: if you open it you will see it there
10:28 PM Tom_L: if you have the source for it
10:29 PM kb8wmc: I have pored over the manuals for the last couple weeks
10:29 PM Tom_L: i was looking at PIN_7I76_34.vhd
10:29 PM Tom_L: which is probably the one loaded
10:30 PM Tom_L: dmesg is your friend
10:30 PM kb8wmc: yep
10:31 PM Tom_L: the pin functions match the card
10:31 PM Tom_L: near as i can tell
10:31 PM kb8wmc: I opened up halrun to see if there was anything in the hm2_pci that would help me
10:31 PM kb8wmc: nothing yet
10:32 PM Tom_L: you have nothing connected yet
10:32 PM Tom_L: once you do it will help
10:32 PM kb8wmc: I have one motor connected, and one limit switch physically connected but non functioning
10:33 PM kb8wmc: motor tests out fine
10:34 PM Tom_L: i don't use halrun alot but it's a valuable tool
10:34 PM Tom_L: start linuxcnc from a terminal with a path to your config
10:35 PM kb8wmc: well, it is not presently helping me out to indicate problem
10:35 PM Tom_L: then in another terminal halrun
10:35 PM Tom_L: halcmd show pin
10:35 PM Tom_L: or halcmd show
10:35 PM Tom_L: will show what you have connected so far
10:36 PM kb8wmc: right now, I would have to comment out the very line I want to check out in order to get lcnc to start
10:36 PM Tom_L: it's gotta be a syntax error then
10:36 PM Tom_L: on that line
10:37 PM kb8wmc: it probably is...
10:37 PM kb8wmc: but I don't see it
10:38 PM kb8wmc: btw, I borrowed and modified both the hal file and the ini for John Thornton's website for his plasma setup
10:38 PM Tom_L: should be good
10:38 PM kb8wmc: I am sure it is...
10:39 PM Tom_L: caps or no caps?
10:40 PM Tom_L: check that
10:40 PM kb8wmc: will do
10:40 PM Tom_L: linux is kinda picky that way
10:41 PM kb8wmc: no joy
10:42 PM kb8wmc: all the underscores and zeros vs 'o' and hyphens and caps are correct
10:44 PM Tom_L: the hal file has 'loadrt hostmot2' in it too?
10:45 PM Tom_L: has to or your motor wouldn't work
10:47 PM Tom_itx: http://gnipsel.com/linuxcnc/configs/pins.html
10:47 PM Tom_L: did you see that/
10:47 PM Tom_L: ?
10:47 PM kb8wmc: correct, loadrt is all good
10:48 PM Tom_L: it may need to know about the sserial for the io to work
10:48 PM Tom_L: add that 7i76 example line if you don't have it
10:49 PM kb8wmc: that is already in my ini file
10:49 PM Tom_L: ok, just eliminating here
10:49 PM kb8wmc: I could move it into the hal file if necessary
10:50 PM Tom_L: it should be in the hal file i believe
10:50 PM Tom_L: was it in the ini?
10:50 PM kb8wmc: simple enough to change
10:50 PM Tom_L: i'm not sure what's 'correct' there but mine is in the hal
10:53 PM kb8wmc: whoa, that didn't work so swell
10:53 PM Tom_L: ?
10:53 PM kb8wmc: lemme look at this a minute
10:55 PM Tom_itx: https://softsolder.com/2013/06/17/mesa-5i25-7i76-hal-pins/
10:55 PM Tom_L: maybe some help..
10:56 PM Tom_L: or just show pins instead of show all
10:59 PM kb8wmc: yes, I have been to his website
11:01 PM kb8wmc: boy, trying to drop the placeholders in the ini file and change the hal file was not the thing to do until I get it squared away in hal
11:01 PM Tom_L: ok
11:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/
11:02 PM Tom_L: different boards but there's my config if it will help at all
11:02 PM kb8wmc: will take a careful look, tnx
11:03 PM Tom_L: there's alot going on there, just look at the basics
11:03 PM Tom_L: and mine is parallel port
11:03 PM Tom_L: not pci
11:03 PM kb8wmc: rgr that
11:04 PM Tom_L: i've got a [HOSTMOT2] section in the ini to define the board
11:05 PM kb8wmc: same here
11:05 PM Tom_L: then you can see how it's referenced in the hal file
11:05 PM kb8wmc: yes, place holders
11:07 PM Tom_L: did you output a dmesg file?
11:08 PM kb8wmc: no I didn't Tom, fact is I have got to bail out of here for tonight, I am beat....not to mention old...lol....where you from?
11:09 PM Tom_L: US
11:09 PM kb8wmc: ok...Michigan here
11:09 PM Crom: now to wait for stuff to start showing up...
11:09 PM Tom_L: i'm sure jt or peter can help you tomorrow
11:09 PM Tom_L: KS here
11:09 PM Crom: SoCal here
11:09 PM kb8wmc: rgr that....thanks much for all your time and help Tom
11:10 PM Tom_L: np
11:10 PM Tom_L: we'll get it
11:10 PM kb8wmc: sure we will
11:10 PM kb8wmc: night to all
