12:01 AM mrec: is it possible to add a button to axis for defining the position of the tool setter? (the button is no problem, but how can I assign the position in an mdi command?)
12:07 AM XXCoder: 25'
01:02 AM mrec: I have a toolchanger nc script, there are some variables assigned eg. #1700 / #1701 / #1702 does anyone know where those variables should be assigned initially when starting up linuxcnc?
01:03 AM mrec: or evenb etter is there a way to store the variables in a configuration file and update them via axis dynamically?
02:01 AM Deejay: moin
02:02 AM mrec: ok just editing linuxcnc.var seems to be enough
02:02 AM mrec: adding the numbers which I want to save
02:57 AM mrec: if [EXISTS[#<_global>]]
02:57 AM mrec: can that be negated?
02:57 AM mrec: if [!EXISTS[#<_global>]]?
02:57 AM mrec: or NOT EXISTS?
03:03 AM rs[m]: [1 XOR EXISTS[#<_global>]]
03:03 AM mrec: NE 0 should do too no?
03:03 AM rs[m]: yes
03:03 AM rs[m]: EQ
03:26 AM mrec: do you know is there a command to force the synchronisation with linuxcnc.var?
03:28 AM rs[m]: no, sorry.
05:14 AM Tom_L: morning
05:19 AM JT-Cave: morning
08:14 AM mrec: hmm any idea why G53 G0 Z80 suddenly gives Linear move on line x would exceed Z's positive limit
08:14 AM mrec: Z79.99 works
08:14 AM mrec: and Z80 also worked before but not anymore for some reason
08:17 AM mrec: I guess it messed around with some tool offsets ...
08:56 AM JT-Cave: no idea but I've seen that before...
08:57 AM XXCoder: mrec: tool length shortens how high it can go and have tool tip go above safe plane
08:57 AM XXCoder: if tool is longer, and volume isnt enough it will be unable to hop over
08:58 AM XXCoder: it could be something else, but thats usually reason
09:05 AM mrec: but why should that affect the machine in the machine coordinate system?
09:05 AM mrec: G53 ..
09:06 AM XXCoder: yeah something else then. not sure then
09:06 AM mrec: the tool height has absolutely nothing to do with the machine limits
09:06 AM mrec: (that's just how I'd understand it)
09:06 AM XXCoder: sorry quite tired (late to bed lol cant sleep lately)
09:06 AM mrec: I added some debug in the code... especially since the "new" limit accepts 79.9
09:06 AM mrec: I'm happy about any feedback, I'm still learning :-)
09:08 AM perry_j1987: morning
09:08 AM perry_j1987: today is the day
09:08 AM perry_j1987: new BOB is arriving lol
09:12 AM perry_j1987: got riser block made for the tool post
09:14 AM perry_j1987: https://i.ibb.co/SmCz5ZX/riser-block.jpg
09:15 AM jdh]: what lathe?
09:15 AM perry_j1987: my lathe of course :)
09:15 AM perry_j1987: http://www.techno-isel.com/Education1/Ed_MetalLathe.htm
09:15 AM perry_j1987: lol
09:16 AM jdh]: looks 'bigger' there.
09:17 AM perry_j1987: in my pic or theirs?
09:17 AM perry_j1987: OXA tool post
09:20 AM asdfasd: anyone managed to make wheezy work with SMB3 ?
09:21 AM asdfasd: I got windows 10 shared folder and cant browse it without SMB1 enabled in windows 10
09:22 AM asdfasd: SMB2 is also enabled but wheezy still cant connect
09:28 AM gregcnc: why didn't you put an AXA toolpost on it?
09:37 AM perry_j1987: i didnt have an axa
09:38 AM perry_j1987: also got a ton of holders for OXA
09:50 AM mrec: does anyone know anything about emcstatusbuffer err=3?
09:50 AM mrec: seems like that bug is in linuxcnc for 10 years at least...
09:58 AM mrec: ok had to start linuxcncsvr (that issue seems to be gone now) checking the next one
10:14 AM perry_j1987: nice
10:30 AM Tom_L: mrec, are you using tool comp?
10:31 AM Tom_L: cutter comp*
10:32 AM mrec: no not at all
10:34 AM mrec: waiting for s.joints<0>, s.kinematics_type<0>
10:35 AM mrec: I'm getting that now and linuxcnc won't start
10:35 AM mrec: I have compiled linuxcnc 2.9 from source
10:36 AM mrec: hmm axis can be started via "linuxcnc"
10:48 AM perry_j1987: which orientation are you suppose to look at the pots on these g320x drives to put them to 11oclock... lol
10:50 AM Tom_L: probably when the silkscreen is in readable position
10:51 AM Tom_L: https://www.geckodrive.com/g320x-digital-servo-drive.html
10:52 AM Tom_L: https://www.geckodrive.com/support/g320x-current-limit.html
10:53 AM Tom_L: even comes with a diagram you can print and color :)
10:54 AM Tom_L: for kids that have never seen an analog watch
10:54 AM mrec: ah I need to start "linuxcnc configfile.ini" instead of axis -ini...
10:54 AM Tom_L: uh huh
10:55 AM perry_j1987: ya i tried looking for those two dots but couldnt make them out
10:55 AM Tom_L: they are likely plastic locators for mounting the pot
10:55 AM Tom_L: just a wag
10:56 AM Tom_L: 12 O'clock would be halfway between full right and full left
10:57 AM perry_j1987: cause i have to limit the current on these for the servos i have 2amp max
10:57 AM Tom_L: put a meter on them
10:58 AM perry_j1987: i dont have a clamp on meter
10:58 AM Tom_L: probably stall current too
10:58 AM Tom_L: Jymmm will sell you one
11:03 AM mrec: haha ... the bug I was complaining about before with the limit is fixed in the latest linuxcnc version
11:03 AM mrec: magically it just works.
11:03 AM Tom_L: 2.8?
11:03 AM mrec: 2.9pre
11:04 AM mrec: changing the endmill messed up the limits it seems
11:04 AM mrec: 2.9 is ok.. 2.8 is messed up it sems.
11:04 AM mrec: seems*
11:05 AM Tom_L: you have the latest 2.8 installed?
11:05 AM mrec: I used the version which came with the iso before
11:05 AM Tom_L: something like that i'd think they would push to 2.8 as well
11:05 AM Tom_L: there have been updates since then
11:06 AM Tom_L: you running buster?
11:07 AM mrec: yes
11:07 AM Tom_L: http://buildbot.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-i386/
11:07 AM Tom_L:
11:08 AM mrec: ok, well it doesn't matter anymore I'll continue with 2.9pre for now
11:08 AM Tom_L: i would be curious if they fixed it in 2.8 though
11:10 AM mrec: I was definitely running 2.8.0 yes unfortunately I killed the installation already.
11:11 AM Tom_L: :/
11:13 AM JT-Shop: 72 labels done... 72 buttons to go
11:13 AM Tom_L: you gettin double time today?
11:16 AM JT-Shop: yea
11:19 AM mrec: Tom_L: oh seems like it's still there
11:19 AM Tom_L: in master?
11:19 AM mrec: but my debugging is now in it
11:20 AM mrec: I set the limit to 80 ... and it's complaining about the target 80.. so seems like the limit just needs to be a little bit bigger
11:20 AM mrec: 80.1
11:21 AM mrec: G53 Z80 does not work ... but I can jog to Z: 80
11:22 AM mrec: Linear move on line 0 would exceed Z's positive Target: 80.00000 (Limit 80.00000)
11:22 AM mrec: looks inconsistent to me
11:22 AM Tom_L: do you have any backlash comp?
11:22 AM mrec: not that I know I have only done the default setup
11:23 AM Tom_L: that would be added in
11:23 AM mrec: but why am I able to jog to 80 with page up?
11:24 AM mrec: nah .. the check in the code checks if it is smaller than the limit
11:24 AM mrec: not smaller or equal
11:24 AM Tom_L: seems like something you should take up with the developers
11:24 AM mrec: in the forum?
11:28 AM mrec: I guess at some point my g-code switches something that this check kicks in
11:28 AM mrec: because after homing it works, after changing the tool it does not work anymore and complains about Z80
11:29 AM mrec: Z79.9999 works so the check should also take equal into account
11:45 AM JT-Shop: 72 buttons installed
11:45 AM JT-Shop: 32 minutes not bad
11:49 AM Tom_L: hope you're not gettin paid by the hr
11:49 AM perry_j1987: lol
11:52 AM JT-Shop: get paid when the last one is installed
11:57 AM * JT-Shop just made a custom screw driver bit from a Phillips bit for the contact blocks
11:57 AM JT-Shop: nap time now
12:00 PM _unreal_: mrec, msg
12:14 PM roycroft: it is time for a big decision that i've been putting off for quite a while - what color to paint my woodworking machines
12:14 PM roycroft: i'm about to put primer on the bandsaw stand, and while that is drying i need to decide and get the color coat paint
12:15 PM roycroft: when i made the stand for my drum sander i was able to demur by getting paint that matched the machine
12:16 PM roycroft: but i've never liked grizzly green, so i want to pick the new color for the bandsaw
12:17 PM _unreal_: roycroft, I guess the best question. is do you care about seeing dirt. does it have lots of tight corners
12:18 PM roycroft: this will be a schema for all my stationary machines
12:18 PM roycroft: and yes, the machines have tight corners
12:19 PM roycroft: i made some faceplates for some electronics test gear with a cranberry color that i really like
12:19 PM roycroft: but i'm not sure i'd like that at the scale of a whole machine
12:19 PM mrec: Tom_L: it's a bug
12:19 PM mrec: I fixed it on my side the gcode works now.
12:20 PM mrec: the double accuracy is not 100% accurate (a programmer should know that...)
12:21 PM roycroft: my woodworking machinery doesn't really get "dirty", _unreal_, so much as it gets dusty
12:21 PM roycroft: and the dust can be blown off easily
12:21 PM _unreal_: mrec, msg
12:24 PM roycroft: i don't want green, and i don't want grey, and i'm using a cobalt blue color for my machine shop tools, so i don't want that
12:24 PM roycroft: actually, a darker green might be ok - i just hate the grizzly green
12:31 PM _unreal_: so go hot pink
12:31 PM _unreal_: its a wood tool I would go a light brown
12:31 PM roycroft: i tried a forest service brown on my belt grinder
12:32 PM _unreal_: maybe even a metallic brown
12:32 PM roycroft: i did not like how it looked
12:32 PM _unreal_: then make it dewalt yellow LOL
12:32 PM roycroft: i thought i would, but ended up repainting it grey
12:32 PM roycroft: no way
12:32 PM roycroft: the powermatic gold-yellow is not too bad
12:32 PM roycroft: but none of my machines are made by powermatic, so that would be a lie
12:33 PM _unreal_: well if you say no to every shade of the rainbow. your last option is CLEAR
12:33 PM _unreal_: LOL
12:34 PM roycroft: this may not seem like a big deal to some, but i have to look at and work with these machines every day
12:34 PM roycroft: it's a decision that will last for years and years
12:34 PM roycroft: which is probably why i've been putting it off for all this time
12:37 PM _unreal_: well you may have to pick a few colors that are with in your range of taste and do a random draw...
12:38 PM perry_j1987: there we go got my new BOB
12:56 PM roycroft: when i build my router table prototype a few years ago i used plastic laminate on the top that is that cranberry color i was taking about earlier, and i mostly liked it but was not totally satisfied with it
12:56 PM roycroft: it's time to rebuild that soon, but i think i'll go look at laminate samples today and if i can find a green that i like i'll just get that
12:57 PM roycroft: i can get paint mixed to match any color i want (mostly), but laminate is what it is, and it is very very expensive to get a custom color plastic laminate
01:01 PM CaptHindsight: you can get epoxy color matched as well or DIY using pigments just like artists do
01:02 PM CaptHindsight: powder coatings are also available in just about any color
01:02 PM roycroft: yes, the paint side is easy
01:03 PM roycroft: it's the plastic laminate that's expensive to custom match
01:03 PM roycroft: so my best bet is to pick a stock laminate color and have the paint matched to it
01:04 PM roycroft: i do a decent job of mixing paints myself
01:04 PM roycroft: i can usually get really close to what i want, although it takes me a while
01:06 PM roycroft: hmm, we have potential snow in the forecast for the end of the month
01:06 PM roycroft: and the temperature might dip down below freezing at night
01:06 PM CaptHindsight: powder coat a piece of aluminum vs using plastic laminate
01:06 PM roycroft: it's been a very mild winter so far
01:07 PM CaptHindsight: wood may also be powder coated but it requires UV powder coat
01:07 PM roycroft: that would be incredibly expensive for a counter top
01:07 PM roycroft: i think i'll be able to find a plastic laminate that i like
01:11 PM CaptHindsight: powder coatings may also be used as pigment=colorant in epoxy, urethane and many other resins
01:12 PM zeeshan: tom so i was asking about using my turning tool to threadmill
01:13 PM zeeshan: guess what i looked closer, it already has a 5 degree clearance built into it.
01:13 PM zeeshan: i'm going to give it a shot today
01:22 PM perry_j1987: https://www.duxe.ru/upload/iblock/483/4839b963cc88bb1442ff49817f1365a5.pdf my new BOB
01:27 PM roycroft: capthindsight: i've been using artist's colors for years - pigment dissolved in walnut oil - to custom blend colors for stains
01:27 PM roycroft: i just got some dry (powdered) burnt umber
01:28 PM _unreal_: cutting my corrected Z limit adjustable trigger arm and the correct one
01:28 PM roycroft: i'm going have a go at mixing that in epoxy to see if i can get colored epoxy that will blend in with wood for stabilizign it
01:29 PM roycroft: if that works, i'll get a dozen or so different dry pigments, and i should be able to mix up just about whatever i want
01:29 PM roycroft: i've never tried this with the artists' colors, but i've been told that the walnut oil carrier in them is incompatible with epoxies
01:30 PM roycroft: i should also be able to mixed the powdered pigments with hide glue to make color-matched glues
01:36 PM CaptHindsight: roycroft: the oils in any of the colors will not react with the epoxy, so you don't want to use that
01:36 PM CaptHindsight: roycroft: dry pigments should work unless they have been treated to make them compatible with water
01:37 PM CaptHindsight: if they have been treated this way they will be far more difficult to disperse in epoxy, solvent and oil based mediums
01:39 PM CaptHindsight: oil in epoxy will just sit there, non-reactive and just make it weaker and softer when cured
01:42 PM Tom_L: zeeshan, lemme know how it goes
01:46 PM _unreal_: milling the last limit switch adapter
01:55 PM gregcnc: zeeshan threadmilling with what?
01:55 PM Tom_L: single point something
01:56 PM Tom_L: turning tool
01:56 PM Tom_L: it's in the log
01:56 PM gregcnc: that triangle insert?
01:56 PM Tom_L: no
01:56 PM Tom_L: that was a chamfer tool he made
01:58 PM gregcnc: i guess I don't see it,or he pulled the google share
01:58 PM Tom_L: which?
01:58 PM gregcnc: this threading tool
01:58 PM Tom_L: i don't think he posted one of the turning tool
01:58 PM Tom_L: just the part he had to thread
01:59 PM Tom_L: M40x1.5
01:59 PM CaptHindsight: his Google shares from last night are all 404 right now
01:59 PM gregcnc: threads are fun
02:00 PM gregcnc: they were last night
02:00 PM CaptHindsight: anyone have a Sunstone TIG? https://www.youtube.com/watch?v=b-_ovorzWkA
02:01 PM CaptHindsight: Micro TIG
02:01 PM CaptHindsight: https://www.youtube.com/watch?v=Y1G7BE6usaM
02:02 PM Tom_L: https://photos.google.com/share/AF1QipOIHOBM6uIS2hX23DVdssH7vR7lcKceRX5mB9NbHOMxhdWT7QDDkB4Sxar_pTIgmQ?key=M3RKb2QwTFdzWGxYZnB2VUdUU1BJTEt6RXFLZGF3
02:02 PM Tom_L: that works
02:03 PM Tom_L: the other ones were proprietary i think is why he pulled them
02:03 PM CaptHindsight: jah
02:03 PM gregcnc: anyhow internal threads aren't terribly complicated, but you can't measure
02:03 PM Tom_L: carbide depot charts are very close
02:03 PM Tom_L: for int and ext
02:04 PM gregcnc: right that's what you'd expect from basic dimensions
02:05 PM gregcnc: I do bastard threads like 17/32"-40
02:06 PM Tom_L: i calculated mine from their charts of a similar thread count
02:06 PM gregcnc: right, it's all based on pitch
02:06 PM Tom_L: for that brass cup i did
02:06 PM Tom_L: which was the purpose of the exercise
02:07 PM perry_j1987: how much are those CaptHindsight
02:09 PM zeeshan: https://photos.app.goo.gl/noEbZyeBuf1JrV4cA
02:09 PM zeeshan: its the turning tool on the left
02:09 PM Tom_L: is it on center when you spin it?
02:10 PM CaptHindsight: perry_j1987: https://sunstonewelders.com/products/micro-tig-welders/
02:10 PM gregcnc: that one will work if you spin on the shaft
02:10 PM perry_j1987: ty i know someone who's prob going to buy one right away
02:10 PM gregcnc: the limiting factor is the nose radius. if too large for the pitch it's unsuitable
02:11 PM CaptHindsight: perry_j1987: likely $13 for a Chinese clone :)
02:12 PM zeeshan: yea it's on center
02:12 PM zeeshan: its 5 degrees slanted from center if that makes sense
02:12 PM zeeshan: gregcnc you've tried?
02:14 PM gregcnc: oh, that has helix
02:14 PM gregcnc: hmmm
02:15 PM perry_j1987: ok think im ready to head over to the shop and start figuring out this wiring
02:15 PM gregcnc: is it in the insert or seat?
02:16 PM zeeshan: ill take a pic in a few min
02:17 PM zeeshan: the whole tool is machined at an angle when you look at it from the end
02:17 PM gregcnc: most are
02:18 PM gregcnc: https://www.carbideanddiamondtooling.com/assets/images/abspgs/3087-2302-0375-pic.jpg3
02:18 PM zeeshan: https://www.kbctools.ca/ecomm_images/items/large/1-289r-172-dia1.jpg
02:18 PM gregcnc: that is irrelevant
02:18 PM zeeshan: why
02:19 PM gregcnc: what is the concern?
02:19 PM zeeshan: if the clearance wasnt there
02:19 PM zeeshan: the back of the tool will rub
02:19 PM zeeshan: as it rotates through the cut
02:19 PM gregcnc: easy enough to check?
02:19 PM zeeshan: spinning this tool vs a single point thread mill
02:20 PM zeeshan: i think its the exact same geometry
02:20 PM gregcnc: right we had a guy thinkign he could do that with a solid carbide
02:20 PM gregcnc: that certainly won't work
02:20 PM roycroft: well jerry's had around 200 different plastic laminate samples, from wilsonart and formica
02:20 PM roycroft: exactly three of them were green, and two of the three were textured
02:20 PM gregcnc: chuck it in your lathe a look?
02:20 PM roycroft: the other was almost identical to grizzly green
02:21 PM roycroft: i ended up getting a yellow green, which is kind of the opposite of what i was originally thinking of, but it's not too yellow, and i think it will look good on the machines
02:21 PM roycroft: it's not like that ugly harbor freight green at all
02:22 PM roycroft: more like john deere green but a bit more subdued
02:24 PM CaptHindsight: husky green vs putrid green
02:25 PM Tom_L: teenage mutant ninja turtle green
02:26 PM gregcnc: https://www.practicalmachinist.com/vb/cnc-machining/laydown-threading-bar-mill-can-you-thread-mill-300462/
02:27 PM unterhaus: client keeps asking my opinion of his spindle design when I already told him it's too long to be made from 1/2" tubing
02:27 PM zeeshan: nice greg
02:27 PM CaptHindsight: unterhaus: ask until you get the answer you want
02:27 PM gregcnc: zeeshan the curious thing is you have a lathe threading bar, where is the lathe that you use it in? is is Zee still latheless
02:27 PM zeeshan: haha still latheless :{
02:27 PM gregcnc: lol
02:28 PM unterhaus: well, at least he increased it from 3/8"
02:28 PM Tom_L: keep collecting lathe tools... eventually it will fix itself
02:28 PM zeeshan: that's what happens when you have a day job that takes 12 hours of your life everyday :D
02:28 PM zeeshan: excuses
02:28 PM unterhaus: hard to do anything after a 12 hour day
02:29 PM gregcnc: I heard everyone is locked in the house in Canada, so maybe you had some time
02:29 PM CaptHindsight: zeeshan: I lost track but I thought you had a CNC lathe with those problematic servo drives
02:29 PM zeeshan: i'm "essential" :D
02:29 PM zeeshan: i am working from home for almost a year now but still need to go to plants
02:30 PM zeeshan: how about you guys?
02:30 PM CaptHindsight: AMC servo drives, that was it
02:32 PM zeeshan: those are on the cnc mill
02:32 PM zeeshan: never using them again:D
02:35 PM unterhaus: what's wrong with AMC drives?
02:35 PM unterhaus: of course, I bought mine cheap
02:35 PM zeeshan: they like to blow up :D
02:35 PM zeeshan: i bought mine cheap too
02:35 PM unterhaus: I can imagine they don't like back emf much
02:35 PM zeeshan: theyre doing the job now but i have a couple spare
02:36 PM jdh]: I have 30 or so at work. they never blow up
02:36 PM unterhaus: I'm sure it depends on the inertia of your application
02:36 PM jdh]: yeah, very little back emf in my application
02:36 PM gregcnc: I forget were you using a voltage shunt or were these integral supply?
02:36 PM zeeshan: also there are far better drives out now
02:36 PM unterhaus: moore nanotech used one for the coolant pump on a lathe I used to run
02:36 PM zeeshan: the plan is to use ethernet drives for the lathe
02:37 PM jdh]: just got a machine with nidec drives. they are actually pretty cool.
02:37 PM unterhaus: I suppose ethernet doesn't work with lcnc?
02:40 PM CaptHindsight: which power tool battery packs have the most power vs cost at the moment?
02:40 PM gregcnc: ethercat right?
02:40 PM zeeshan: ethernet ip cip motion
02:40 PM zeeshan: i dont think there is a driver for linuxcnc using it
02:41 PM CaptHindsight: there is some Russian outfit selling it with their own FPGA cards
02:42 PM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EtherCatDriver
02:42 PM CaptHindsight: https://www.youtube.com/watch?v=QJU3q5N35jg
02:42 PM CaptHindsight: LinuxCNC+Ethercat+EpoCAT+JMC
02:43 PM zeeshan: ethercat and ethernetip are diff
02:43 PM gregcnc: ah
02:43 PM Tom_L: aparently licensing issues prevent official support
02:43 PM CaptHindsight: CNC Setup: LinuxCNC,EtherCAT and IndraDrive https://www.youtube.com/watch?v=yR9rCFavFjU
02:43 PM zeeshan: ethernet ip uses the cip (common industrial protocol)
02:44 PM zeeshan: its very common in industrial applications
02:44 PM zeeshan: i want to learn more by using it
02:44 PM jdh]: dewalt or milwaukee for longevity. waitley dewalt clones for cost but less overall life
02:47 PM CaptHindsight: jdh]: I'm considering converting some older cordless, just looking for a decent pack to adopt
02:48 PM CaptHindsight: though they often give the tools away to get you locked into their batteries
02:49 PM jdh]: for the little batteries, there isn't much difference
02:59 PM zeeshan: has anyone used the clearpath servos?
03:00 PM CaptHindsight: closed loop steppers?
03:04 PM unterhaus: nowadays there are converters between most major brands
03:04 PM unterhaus: I'm a lot less concerned about which tools to buy
03:04 PM unterhaus: I have dewalt and milwaukee tools
03:05 PM unterhaus: thought about picking up some ryobi because there are dewalt converters
03:05 PM unterhaus: also, there are dewalt battery to makita tool converters
03:06 PM unterhaus: there are sales right now, so it's probably the time to buy. dewalt is most supported
03:07 PM CaptHindsight: the online reviews are near worthless
03:10 PM CaptHindsight: zeeshan: i used these https://www.amazon.com/Stepper-Integrate-Position-Encoder-Control/dp/B01MFA87KI/ref=sr_1_6
03:10 PM CaptHindsight: since they were available for same or next day delivery
03:11 PM CaptHindsight: mine worked great, don't know how well their QC is, so i might have gotten the lucky good ones
03:26 PM perry_j1987: hmm so these BOBS typically have the relays setup where the middle pin is the pin and outer contacts on the terminal strip are the relay right?
03:27 PM unterhaus: the client bought a bearing that has more than 1/32" end slop. Going to take more than wavy washers
03:29 PM CaptHindsight: perry_j1987: nothing is standard
03:30 PM CaptHindsight: perry_j1987: if the relay part number is visible, look for the data sheet
03:30 PM perry_j1987: aye looking for english versions now
03:32 PM CaptHindsight: perry_j1987: which BOB are you trying this time?
03:35 PM perry_j1987: https://www.duxe.ru/upload/iblock/483/4839b963cc88bb1442ff49817f1365a5.pdf
03:37 PM perry_j1987: got spindle encoder and limit switches wired up to it now and 0-10v wired up. gotta setup one of the relays to enable run on the vfd
03:38 PM perry_j1987: so i think i'd wire wires up to the left two terminals on the first relay i believe
03:38 PM CaptHindsight: heh the info in that pdf is terrible
03:39 PM perry_j1987: russian site heh
03:39 PM CaptHindsight: when i was in China they would never ask me (the native English speaker) to proofread anything
03:39 PM perry_j1987: i've been pouring over this pdf all morning hehe
03:40 PM perry_j1987: they'd be powerful if thy just.... hired some native english tech writers lol
03:40 PM gregcnc: people buy any, so this is cheaper
03:40 PM gregcnc: anyway
03:42 PM perry_j1987: so these g320x need enabled after power up
03:43 PM perry_j1987: in stepconf what option do i choose for that feature on one of the pins
03:43 PM CaptHindsight: ON - MID - OFF for the relay connections
03:43 PM CaptHindsight: thanks for making that CLEAR
03:43 PM perry_j1987: is that amplifier enable
03:43 PM CaptHindsight: yes, amp/drive enable
03:44 PM perry_j1987: im going to configure the pin for the relay and just start it up with it not hooked up. enable the spidnle and see the relay engage and then check continuity with it on
03:48 PM CaptHindsight: other suggested relay contact names: Yes, Maybe, No
03:48 PM perry_j1987: haha
03:48 PM CaptHindsight: Fred, Barney, Tom
03:48 PM CaptHindsight: Away, Uh Huh, more back from
03:48 PM gregcnc: mid is like when the light switch gets stuck half way
03:49 PM perry_j1987: that'd be too useful. it'd prob be 是的,也许,否
03:49 PM Tom_L: hey now!
03:51 PM CaptHindsight: go from to now, OK?
03:52 PM perry_j1987: with the board off, there's continuity between on and mid
03:53 PM CaptHindsight: On = Normally Closed
03:53 PM CaptHindsight: brilliant
03:53 PM CaptHindsight: i probably won't be able to understand data sheets 20 years from now
03:55 PM Tom_L: they will unfold like a talking birthday card
03:58 PM perry_j1987: can you guys help me understand pin 12 on g320x drivers
03:58 PM perry_j1987: it says to tie it to either 5v or gnd
03:59 PM jdh]: for sourcing or sinking?
04:03 PM CaptHindsight: https://www.geckodrive.com/amfile/file/download/file_id/17/product_id/21/
04:04 PM perry_j1987: ah so it just sets up the step/dir instead of inverting the signal in stepconf
04:05 PM CaptHindsight: it doesn't help that gecko mention pin 10 in one sheet and pin 12 in another as the S/D common
04:05 PM perry_j1987: yep
04:06 PM perry_j1987: g320 vs g320x differences i think
04:06 PM CaptHindsight: nah, can't be bothered with details
04:11 PM perry_j1987: any reason to go one way or the other?
04:12 PM CaptHindsight: depends on your hardware, some BOB's or control cards might be only one way or the other
04:13 PM CaptHindsight: Gecko lets you configure for either
04:19 PM perry_j1987: k
04:19 PM perry_j1987: now to figure out these dip switches
04:39 PM perry_j1987: hmm
04:39 PM perry_j1987: new board in got limitswitches and encoder hooked in
04:39 PM perry_j1987: hal meter shows no activity
04:39 PM perry_j1987: put multimeter on the encoder pins and i see voltage changes when i rotate the chuck by hand
04:40 PM perry_j1987: axis complains about joint 0 and joint 2 limit error
04:40 PM Tom_L: invert the logic?
04:42 PM perry_j1987: would still show activity on hal meter even though right?
04:47 PM perry_j1987: just litterally had another bob on here and encoder and limitswitches were working heh
04:58 PM unterhaus_: I have a 1/2" threaded rod mounted in the lathe with lead strips wrapped around it and the steady rest
04:58 PM CaptHindsight: no help here, just nonsensical info from the data sheet: e. DIR is for direction. Now, take the con1) EN+ and EN- cannot connect wires.
04:58 PM unterhaus_: questioning my life choices
04:58 PM CaptHindsight: ask you mom?
04:59 PM perry_j1987: what is a charge pump
04:59 PM unterhaus_: oh, it's sticking out 18" from the chuck. First one went okay though
04:59 PM CaptHindsight: But they are low level trigger.
05:00 PM CaptHindsight: perry_j1987: But they are low level trigger. the switch inputs
05:00 PM unterhaus_: charge pump is an rc circuit that will decay to zero if you give it the right amount of time
05:00 PM unterhaus_: used mostly for timers
05:00 PM perry_j1987: what do i want it set to on this BOB
05:00 PM perry_j1987: theres a jumper of some sort
05:01 PM CaptHindsight: have do do some circuit inspecting to see
05:01 PM CaptHindsight: instructions are terrible
05:02 PM gregcnc: unterhaus consider a spider if you have many to do https://www.practicalmachinist.com/vb/gunsmithing/how-run-barrel-steady-rest-without-marring-bluing-362496/#post3335554
05:03 PM perry_j1987: none of the inputs are working on this board
05:04 PM perry_j1987: voltages change on the pins when i press a switch etc
05:06 PM CaptHindsight: perry_j1987: which pins?
05:07 PM CaptHindsight: how are your switches currently wired to this BOB?
05:08 PM perry_j1987: one side to gnd other side to one of the input pins
05:13 PM perry_j1987: series
05:16 PM perry_j1987: ok this is weird
05:16 PM perry_j1987: if i enable one of the servos it starts holding position
05:16 PM perry_j1987: i can grab shaft and see the lights work properly on the g320x driver
05:17 PM perry_j1987: but... the pycvp panel for spindle speed i can see it move up little as i try moving the servo
05:17 PM perry_j1987: i swear the encoder for the servo is in no way wired to the BOB lol
05:17 PM perry_j1987: what the hell is going on
05:23 PM perry_j1987: ok got everything disconnected but the limit switches
05:26 PM CaptHindsight: was away
05:27 PM CaptHindsight: ah I bet you have to use a common high vs the low you had used for the switches
05:27 PM CaptHindsight: since the data sheet sort of said active low inputs
05:30 PM perry_j1987: pin 13 that i have the limit switches on shows 5v between it and gnd right now
05:37 PM CaptHindsight: does it go to 0V when the switch is closed?
05:38 PM perry_j1987: ya

05:43 PM XXCoder: nice
05:50 PM perry_j1987: ok i downloaded that parport tester from the wiki
05:50 PM perry_j1987: wonder if my parport is jacked
05:51 PM perry_j1987: everything red pin15 green
05:51 PM perry_j1987: if i press pin 2 then pin13 input lights up heh
05:51 PM perry_j1987: if i press pin 6 then pin 11 and pin13 inputs light up
05:51 PM perry_j1987: what does this mean
05:53 PM perry_j1987: ima run home and grab one of my parport addon cards
05:53 PM perry_j1987: bbiab
06:03 PM perry_j1987: ok before i go i just put this other BOB i got on here rebooted
06:03 PM perry_j1987: its reading everything fine
06:03 PM perry_j1987: did i really get two broken BOBS in a row lol
06:09 PM unterhaus_: client just asks me if he should bolt something together or have it welded
06:09 PM unterhaus_: I told him to make it out of extrusion like every single other engineer on the planet
06:10 PM unterhaus_: how does it feel to be the only engineer that would do this? is never a question you want someone to ask you
06:45 PM CaptHindsight: wood, you do it!
07:09 PM roycroft: my parts look very green
07:09 PM roycroft: but i think i'll like the color in the end
08:20 PM perry_j1987: got it working

09:11 PM perry_j1987: trying to figure out how to calibrate the steps per mm with these servos and this g320x driver heh
09:17 PM Tom_L: perry_j1987, dunno if this will help or not... https://forum.linuxcnc.org/10-advanced-configuration/32367-servo-tuning-detailed-how-to
09:19 PM Tom_L: perry_j1987, what's the encoder resolution?
09:20 PM perry_j1987: ah just got it
09:20 PM perry_j1987: calculated it
09:20 PM veegee: perry_j1987 just eyeball it
09:20 PM Tom_L: and that's why veegee buys forklifts and not cncs
09:21 PM veegee: damn, nicely done!
09:21 PM Tom_L: :)
09:21 PM veegee: although I did put a watch for VMCs on kijiji, they're super expensive
09:21 PM veegee: Like minimum $30,000
09:21 PM Tom_L: good ones are even more
09:28 PM veegee: Yeah I don't need a production machine
09:28 PM veegee: I just do prototypes
09:28 PM veegee: Accuracy and rigidity is important to me, speed doesn't really matter
09:31 PM perry_j1987: hey guys spindle encoder scale? how is that all calibrated
09:31 PM perry_j1987: to display the proper speed
09:31 PM Tom_L: have a look at my configs
09:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/
09:32 PM perry_j1987: im not familiar how it works
09:33 PM Tom_L: setp hm2_[HOSTMOT2](BOARD).0.encoder.01.scale 2000.
09:33 PM Tom_L: but you're not using a mesa card
09:35 PM Tom_L: net spindle-velocity hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity => near.0.in2 scale.0.in spindle.0.speed-in
09:36 PM Tom_L: wait.. that scale is for the display, ignore it
09:37 PM perry_j1987: so its based on the ticks on whatever encoder i got in here
09:38 PM perry_j1987: which is unknown to me atm i have to take that out to see if there's numbers but i could prob guestimate pretty close to narrow it down i gues
09:38 PM Tom_L: you need to scale that for the pwm to the analog signal for the vfd
09:38 PM Tom_L: 0-10v
09:39 PM Tom_L: setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.scale 6000
09:39 PM Tom_L: there again, yours will be different
09:40 PM CaptHindsight: perry_j1987: what was wrong with the 2nd BOB 2 hours ago?
09:45 PM perry_j1987: no inputs
09:45 PM perry_j1987: zero
09:45 PM perry_j1987: and zero outputs
10:05 PM Thorhian: So, I am not rich, or super well off, but I need a somewhat decent way to cut 1.5" thick aluminum bar stock that will be 5" wide along with 2" steel tube. Will a cheapo harbor freight H. Bandsaw get the job done decently or would that be a no-go zone?
10:06 PM Tom_L: the 5" wide might present a problem for a small bandsaw
10:07 PM roycroft: if you're talking about a stationary bandsaw, the hf 4x6 can do an ok job if you are willing to spend some time dialing it in when you get it
10:07 PM Tom_L: as i read that, is it a 5" wide 1.5" thick plate?
10:07 PM roycroft: the 7x12 would do a much better job
10:07 PM roycroft: if you're talking about a portable bandsaw forget it
10:08 PM Tom_L: i cut all my square tubing with a cutoff blade
10:08 PM Tom_L: wouldn't do much for aluminum
10:08 PM roycroft: i use my bandsaw for all cutoffs
10:09 PM roycroft: it's the quiestest way to do it
10:09 PM Tom_L: i don't have one
10:09 PM Thorhian: I would prefer the 7x12 roycroft but I can't afford the extra $750 difference it is compared to the 6x4.
10:09 PM roycroft: if i did not have one i would not use it either
10:10 PM roycroft: thorian: the 4x6 works ok, but it needs some squaring up when you get it
10:10 PM roycroft: also, for that 1.5"x5" plate, do not cut it flat
10:10 PM roycroft: stick a pice of 1/2" pipe underneath one side of it so you're cutting it at an angle
10:10 PM Thorhian: I am looking at this one basically, not a portable one
10:10 PM Thorhian: https://www.harborfreight.com/power-tools/power-saws/band-saws-scroll-saws/horizontal-vertical-metal-cutting-bandsaw-93762.html
10:10 PM roycroft: and don't use too fine a blade for aluminium
10:11 PM Tom_L: are you sure that 5" will fit that?
10:12 PM roycroft: it's a 4x6
10:12 PM roycroft: 5" will fit fine
10:12 PM Thorhian: I mean, it's a 1.5" x 5" piece of stock.
10:12 PM Tom_L: so between the vise jaws is 6"
10:12 PM roycroft: it really does open 6" wide
10:12 PM roycroft: and really does cut 4" thick
10:12 PM Thorhian: It seems you have experience with it roy lol?
10:12 PM roycroft: yes, i used to have one
10:12 PM Tom_L: don't know alot about how they size a bandsaw
10:12 PM roycroft: i have a 7x12 now
10:13 PM Thorhian: I really want the 7x12 lol, but I can't justify the cost in my situation lol, especially if the $280 one can do it for now and help me make money instead of hacking away with a hack saw all day.
10:14 PM roycroft: the 7x12 is a much better saw
10:14 PM roycroft: but if cash is an issue, buy the 4x54
10:14 PM Tom_L: my friend used to use a chop saw
10:14 PM roycroft: 4x6
10:14 PM roycroft: spend some time fixing it up
10:14 PM Tom_L: another friend, not the one with the shop
10:14 PM roycroft: put a hydraulic downfeed on it
10:14 PM roycroft: use it for a year
10:14 PM roycroft: then buy the 7x12 and sell the 4x6 for what you paid for it
10:15 PM roycroft: if you make a few improvements to it, especially the hydraulic downfeed, you can get your $280 back for it
10:15 PM Thorhian: You recommend adding hydraulic feed? Is that difficult on this thing or not really?
10:16 PM roycroft: i had my 4x6 for several years, and one reason i kept it so lon is that i was doing a lot of field work, and i could lift that machine into my van by myself
10:16 PM roycroft: i can't do that with the 7x12
10:16 PM Thorhian: XD Yeah I bet.
10:16 PM roycroft: yes, adding a hydraulic downfeed is easy and recommended
10:16 PM roycroft: teh youtube should have all sorts of 4x6 mod videos
10:17 PM Thorhian: Sounds good. I was thinking of buying one this week so I didn't have to pay a lot of extra money for getting steel tubes cut for building a stand for my milling machine.
10:17 PM Thorhian: ALong with the stock I plan to mill on the mill itself lol
10:17 PM roycroft: is your hf far away?
10:17 PM Tom_L: i sometimes use an endmill to cut stock off
10:17 PM Thorhian: Nope, a new one just opened in the town/city where I live.
10:17 PM roycroft: cool
10:18 PM Tom_L: wastes a little but alot quicker than a hacksaw
10:18 PM roycroft: the one thing that's often a problem and that you can't easily fix is the pivot pin
10:18 PM roycroft: sometimes it's crooked
10:18 PM roycroft: sometimes it's loose
10:18 PM roycroft: there's really no way to know until you set it up
10:18 PM roycroft: so be prepared to take it back for a different one if that is a problem
10:18 PM Thorhian: I've read that a worm gear inside of it can have some nasty burs that destroy the brass gear it gets driven by as well.
10:19 PM Thorhian: Along with being packed with terrible grease.
10:19 PM roycroft: i never had a problem with that on my 4x6, but my 7x12 brass worm gear wore out
10:19 PM roycroft: i replaced it with a steel one from grizzly
10:19 PM roycroft: and it's been working fine for years
10:20 PM Thorhian: I think initially I'll make sure to debur the worm gear lol, and maybe get some decent oil for it.
10:21 PM Tom_L: is northern tool a chain like HF?
10:21 PM Tom_L: or just a local thing
10:21 PM roycroft: BesseyClamps.jpeg
10:21 PM roycroft: ack
10:21 PM Tom_L: https://www.northerntool.com/
10:21 PM roycroft: www.roycroft.us/7x12Gear.jpeg
10:21 PM roycroft: that's what i meant to post
10:21 PM roycroft: northern tool are not a chain
10:22 PM roycroft: they're a big store in grand forks north dakota
10:22 PM roycroft: that do a lot of online sales
10:22 PM Tom_L: u tore the shit outta that gear!
10:22 PM roycroft: yeah
10:22 PM roycroft: that happens to them
10:22 PM JavaBean: northern tool is a chain, i have one locally
10:22 PM roycroft: the steel one, i'm sure, still looks brand new
10:22 PM roycroft: it's a chain now?
10:22 PM Tom_L: we've got a northern here is why i wondered
10:22 PM roycroft: it did not used to be a chain
10:22 PM Tom_L: you might see what they've got too
10:23 PM Tom_L: i dunno
10:23 PM Thorhian: Never heard of them
10:23 PM Tom_L: k
10:23 PM roycroft: i would not order an import 4x6 online
10:23 PM roycroft: they're all essentially the same
10:23 PM roycroft: and all have that pivot pin issue
10:23 PM Thorhian: I'm guessing it's a pin that the whole saw assembly rotates around?
10:24 PM Tom_L: i've never purchased from northern but think they're about the quality of HF junk
10:24 PM roycroft: it's the pin that connects the top to the bottom
10:24 PM roycroft: if it's crooked then you will never get a square cut
10:24 PM roycroft: no matter what you do
10:24 PM roycroft: the blade will be coming down at an angle
10:24 PM Thorhian: So as soon as I get it I should make sure it is straight.
10:24 PM roycroft: yes
10:24 PM roycroft: anything else that's wrong you can fix
10:25 PM roycroft: you can fix that too, but it would cost you more than $280 worth of your time to do so
10:25 PM Thorhian: Hmm, sounds good. Got any guides you like to make sure it's in fit condition when I get it?
10:26 PM roycroft: i don't
10:26 PM roycroft: i bought my 7x12 over 10 years ago, and sold the 4x6 as soon as i got it
10:26 PM Thorhian: Lol don't blame you.
10:26 PM roycroft: i did not keep any documentation or links
10:27 PM Thorhian: Not surprised the Grizzly part works on it though lol
10:27 PM roycroft: but there's a 4x6 bandsaw group that was on yahoo groups
10:27 PM roycroft: i think it moved to groups.io
10:27 PM roycroft: you might see if it did, and peruse the archives there
10:29 PM roycroft: for the aluminium bar stock, get a coarse tooth blade and urn it as fast as it goes
10:29 PM roycroft: run, rather
10:29 PM roycroft: that saw has an open stand, which makes it challenging to add a coolant pump
10:30 PM roycroft: you don't need coolant for the aluminium, for heat, but a flood coolant system would clear the chips for you
10:31 PM roycroft: if you don't mind the mess, a small air nozzle would help clear the chips if it becomes a problem
10:33 PM Thorhian: Do you need coolant for cutting thicker steel? I think I will be fine with the tubing I want to cut ATM.
10:35 PM roycroft: get yourself a white taper candle
10:35 PM roycroft: hold the candle in the blade once in a while as you're cutting the steel and you'll be ok
10:36 PM roycroft: you could use something else like carnauba wax, but a candle will be cheap and works fine
10:36 PM Tom_L: i've used bar soap in a pinch
10:36 PM roycroft: that would work
10:39 PM roycroft: you could probably even break into your jar of retirement grease and dab a little of that on the blade
10:41 PM JavaBean: with the blade not running
10:42 PM roycroft: yes
10:42 PM roycroft: i apply the candle with the blade running
10:42 PM roycroft: but if i were to use the retirement grease i'd turn it off first
10:43 PM JavaBean: retirement greese is what made me make that comment
10:43 PM roycroft: of course, not being a meat eater, i have no retirement grease
10:44 PM roycroft: but i assume groundskeepr willie is not the only person with a stash
10:44 PM JavaBean: you consumened anchovies the other day
10:44 PM roycroft: yes
10:44 PM roycroft: i'll clarify
10:45 PM roycroft: i don't eat birds and mammals
10:45 PM roycroft: most people don't care about the details
10:45 PM roycroft: i consumed anchovies again today, btw
10:45 PM roycroft: because i had a slice of leftover pizza
10:45 PM roycroft: and i have a couple slices left for lunch tomorrow
11:13 PM roycroft: grrr
11:13 PM roycroft: i haven't seen a fruit fly since october, when they always go away for the year
