[00:21:37] <Wolf_> hmm, touch screen on lcnc… opinion?
[00:23:31] <archivist> available to those that want it
[00:24:19] <Wolf_> wondering if its worth it or not
[00:26:03] <archivist> depends how you use linuxcnc
[00:26:32] <archivist> if develop gcode on another machine then ok else...
[00:27:41] <Wolf_> most of the time I do that
[00:31:07] <roycroft> i'll have a touch screen + full keyboard
[00:31:13] <roycroft> but no pointing device
[00:31:26] <roycroft> i'll likely have joysticks for jogging though
[00:32:15] <Wolf_> I was thinking mpg pendant + touch screen and keyboard for those odd times
[00:32:46] <roycroft> i'm going to plan for a pendant but not get a pendant or pendant interface at first
[01:10:36] <archivist> Wolf_, I tried the 433 transmitter receiver pair yesterday, needs to send a word/byte as it does not sit high/low like I hoped
[01:15:40] <Wolf_> yeah, I think most are serial data =/
[01:16:18] <archivist> does mean a little latency
[01:19:20] <Wolf_> yeah =\
[01:19:24] <Wolf_> sleep time here...

[05:15:22] <Deejay> re
[05:32:09] <jthornton> morning
[05:32:44] <XXCoder> hey jt
[05:32:53] <XXCoder> something stupid happened at work
[05:33:03] <XXCoder> my pants zipper broke :P
[05:33:28] <XXCoder> so had to use safety pin and zip tie to hold it together till shift ended
[05:36:10] <jthornton> lol
[05:37:41] <XXCoder> lovely way to end rather hellish day
[05:41:46] <Tom_itx> at least you didn't rip the seam out bending over etc
[05:41:55] <XXCoder> happened to me
[05:41:58] <jthornton> lol
[05:42:03] <XXCoder> I was hours away from home
[05:42:23] <XXCoder> so I had to creatively fold pant and shuffle around store to buy a pant
[05:49:17] <MacGalempsy> good 1119 utc
[05:49:32] <XXCoder> no idea what that is heh
[05:50:00] <Deejay> good 1220 cet
[05:50:03] <MacGalempsy> heh. good morning but euro sensative
[05:50:27] <Deejay> had lunch :)
[05:50:30] <MacGalempsy> hey deejay. whats going on?
[05:50:32] <Deejay> morning is over
[05:50:59] <MacGalempsy> its 0521 here.
[05:51:10] <Deejay> somewhat early ;)
[05:51:41] <MacGalempsy> yeah. bad dreams. and the wife and dogs are snoring loud
[05:51:48] <Deejay> lol
[05:52:03] <XXCoder> 0323 here :P
[05:52:06] <Deejay> you need earplugs
[05:52:12] <MacGalempsy> lok.
[05:52:23] <Deejay> XXCoder is a "night owl" ;)
[05:52:29] <MacGalempsy> lol i tried but the hurt after a while
[05:53:11] <MacGalempsy> you cannot soar with eagles if you are up hooting with the owls ;)
[05:53:51] <XXCoder> wouldnt know if any owls here
[05:54:46] <MacGalempsy> we have a few here, but yesterday we had over 40 buzzards in the front trees
[05:55:23] <Deejay> uh
[05:55:59] <MacGalempsy> kind of scarey as yhe
[05:56:08] <MacGalempsy> they are quite large
[05:56:57] <Deejay> hope they do not eat your hair from ya head ;)
[05:57:12] <MacGalempsy> yeah!
[05:57:45] <MacGalempsy> i definitely wont be playing dead in the yard
[05:57:58] <XXCoder> lol
[05:58:20] <XXCoder> you sure you arent in s. king book birds? ;)
[05:59:10] * MacGalempsy puts on a suit of armor when retrieving the post
[05:59:33] <MacGalempsy> arm the crowbot!
[05:59:54] <XXCoder> ironcrow
[05:59:57] * jthornton carries a pistol to check the mail
[06:00:11] * XXCoder carries kindle pw2 to check the mail
[06:00:19] <MacGalempsy> bears or methies?
[06:00:26] <jthornton> https://www.youtube.com/watch?v=7y8uSGIgVBY
[06:00:33] <jthornton> dog
[06:01:17] <Deejay> lol
[06:01:36] <XXCoder> ironwoof
[06:02:00] <MacGalempsy> ah. we have a mastiff that roams our hood. we nicknamed him hurcules
[06:02:36] <MacGalempsy> caught him in our back yard a few times, but he generally runs away
[06:03:44] <jthornton> the neighbors to the north have 3 huge shaggy white dogs and one time a thunderstorm one crawled into the crawler seat to hide
[06:05:30] <MacGalempsy> we do have bears tho, neighbor claims one was in his yard.
[06:06:20] <jthornton> a guy the next road over had one on his porch eating dog food out of the garbage can he used to keep it in
[06:08:44] <jthornton> http://dogtime.com/dog-breeds/great-pyrenees#/slide/1
[06:08:52] <jthornton> I think they are that dog
[06:11:43] <MacGalempsy> those are like 100+lbs
[06:13:16] <jthornton> yea one is huge like 150 lbs
[06:19:46] <jthornton> https://www.youtube.com/watch?v=fYM2Pfr5XOk
[06:21:26] <MacGalempsy> just think that video made that guy $17+k
[06:23:17] <MacGalempsy> $7.60/1000 views
[06:24:32] <MacGalempsy> https://youtu.be/aWZY2FlhtIk
[06:30:56] <MacGalempsy> wow. those swedes got whooped bad
[06:53:29] <XXCoder> 100 bucks. http://s3.crackedcdn.com/phpimages/article/0/0/5/594005_v3.jpg
[06:53:31] <XXCoder> geez.
[07:01:23] <MacGalempsy> what is it?
[07:01:42] <XXCoder> its floor sweeper ripoff that cleans grill surfaces
[07:03:28] <gregcnc> you don't make $7.60/k on yt
[07:05:33] <MacGalempsy> thats what i read when asking google how much pewdiepie is worth
[07:06:00] <MacGalempsy> says he had 11 billion views
[07:06:34] <gregcnc> it varies
[07:13:51] <MacGalempsy> they put that guy at $61m after taxes!
[07:14:40] <XXCoder> thats basically can retire
[07:17:00] <MacGalempsy> with a cocaine habit
[07:19:02] <gregcnc> the more views you get the better the rate, the range is quite large
[07:23:26] <gregcnc> I have a video approaching 4M views soon, nowhere near 7.60/1000
[07:26:56] <jthornton> you get paid for putube videos?
[07:27:21] <MacGalempsy> yeah
[07:27:42] <MacGalempsy> was just reading the criteria
[07:35:57] <Frank_6> yeah pewdiepie is the n1 youtuber in views
[07:46:54] <gregcnc> the ones who make the compilations are making money for basically nothing
[07:50:41] <XXCoder> no wonder that seem to be everything
[07:50:44] <XXCoder> *everyhere
[07:51:44] <MacGalempsy> it has to be original video and music
[07:52:25] <MacGalempsy> not sure compilations qualify unless you can get signoff on original content
[08:04:45] <gregcnc> compilations fall under fair use if there is some commentary, besides you'd have to find your video to make a claim
[08:04:58] <gregcnc> so unless you have an army of followers doing it for you...
[08:17:15] <Frank_6> guys, is the linuxcnc alarm clear needed on a servo driver? or it is used to switch the drive off/on to clear the alarm?
[08:28:33] <MacGalempsy> Frank_6: I think it depends on your drive
[08:29:19] <MacGalempsy> it would be good to have them power on when the machine turns on, then use ENABLE, RESET, and FAULT INDICATOR
[08:29:53] <MacGalempsy> ENABLE and RESET are HAL outputs, and FAULT INDICATOR is an input
[08:31:42] <Frank_6> exactly, i didnt knew if they were usual outputs that are easy to program, the tricky thing in my case is that i have to use a relay for each output to the drive,
[09:50:28] <ktchk> koppi bipokins???
[10:05:34] <miss0r> wtf mate? :)
[10:07:04] <miss0r> I am building a somewhat highspeed spindle, to attach my maho mill in the ISO 40 collect. Sort of an extender with an electric motor inside of it. I am looking into these 3-phase brushless dc motors made for RC vehicles. Do any of you have any thoughts on this/experience with these types of motors?
[10:07:46] <gregcnc> they work fine if chosen correctly for the loads
[10:07:59] <gregcnc> most don't have hall sensors
[10:08:13] <sync_> can't you just put a chinese spindle on the side of your vertical head casting?
[10:08:23] <sync_> it should be flat so you can just tap a few holes
[10:09:23] <miss0r> sync_: Yeah, well - I was planning to do around 40k rpm. I haven't found a descent chinese spindle that can do anywhere near that speed. Come to think of it, I haven't stumbled across a descent chinese spindle at all
[10:09:37] <sync_> well, they work fine
[10:09:45] <sync_> but there are a few out there doing 60k
[10:09:51] <sync_> or you get a precise spindle
[10:10:05] <sync_> but attached to the side is always better than running one in the spindle
[10:10:08] <sync_> as you have a lot of room
[10:10:19] <gregcnc> main problem of DIY spindle is balancing
[10:10:25] <miss0r> I must admit not having alot of experience with chinese spindles, other than the one that came with my first cnc router. a 3040 generic chinesium off of fleabay
[10:10:30] <miss0r> and that thing was awfull
[10:10:32] <sync_> not really, two accels and you can dynamically balance it
[10:11:06] <gregcnc> easy as pie right?
[10:11:11] <miss0r> sync_: You have the balancing sound simple, but I must admit, that is what I am worried about with this build
[10:11:29] <sync_> it is not incredibly hard
[10:11:44] <sync_> you put two accels on there and something to index the shaft
[10:11:48] <gregcnc> if you understand what your doing no
[10:11:50] <sync_> and then you just look at it on the scope
[10:12:24] <miss0r> I get the concept. and I have a pretty nice scope with a hold function. so all I need is an accelerometer? :)
[10:13:12] <sync_> you do not need a hold function
[10:13:29] <miss0r> or two for that matter.... I will cross that bridge when I get there. For the rotating shaft, I was planning to buy a er11 collect chuck with a ground extention shaft. That will be chinesium for sure. but sometimes I get lucky
[10:13:32] <sync_> yes, you need one or two accels that output an analog signal
[10:13:43] <sync_> and a photodiode
[10:14:52] <miss0r> I must admit balancing shafts have always intrigued me. I think I will do that at some point, and not only if the thing vibrates off the table
[10:16:12] <miss0r> I am planning to place two angular contact bearings, back to back as close to the er11 chuck as possible. and then have a regular ball bearing in the read of the shaft. Is this within reason or am I missing some basics?
[10:16:33] <gregcnc> 40k is fast, and will run hot
[10:17:11] <gregcnc> ideally the back bearing is also precision
[10:17:21] <gregcnc> and allows float
[10:17:56] <miss0r> indeed. I am going to drill through holes, running parallel with the direction of the shaft, in the outer housing. thoes will be connected in the endcaps, and allow for coolant to flow
[10:18:37] <miss0r> My worrie is that only cooling the outer housing will cause problems.
[10:19:12] <gregcnc> waht else would you cool?
[10:19:29] <miss0r> I will also have a small air flow going out in the chuck end, to discourage chips from getting into the bearings.
[10:20:05] <miss0r> perhaps applying an oilmist(way out of my confort zone) to the bearings. this way I would cool/lubricate them more evenly, than just the outer ring
[10:20:59] <miss0r> the heating will be done on both the inner and outer race of the bearings. I'm fearing only cooling the outer one would cause clearence issues ?
[10:24:15] <miss0r> clearly I need to do some more reading before I start ordering components
[10:24:55] <sync_> I would exchange ordering compoments for ordering a spindle ;)
[10:25:07] <sync_> while it is a fun project, if you want to use it, just get a used precise spindle off ebay
[10:25:51] <miss0r> I want to use it :) ofcourse I do. but have you seen the pricetags on thoes things?
[10:27:33] <gregcnc> i have built one, I'd also buy unless what you need doesn't exist
[10:27:37] <sync_> yes miss0r
[10:27:43] <sync_> ~300-400€ used
[10:27:57] <sync_> spindle rebuild is about the same for them at precise if they need it
[10:28:18] <miss0r> yeah. I'm thinking I can build one myself for around 100eur. that and I get a fun new project :)
[10:28:47] <sync_> good luck
[10:28:47] <gregcnc> 100 euro will not build a decent one
[10:29:08] <gregcnc> you'll spend that on p4 bearings alone
[10:30:24] <miss0r> I was looking at some 7001 angular contact bearings, those are 25eur each. and a regular precision bearing will set me back around 10-15 eur.
[10:31:11] <sync_> look at the tolerance the inner race has in regard to the trajectory follows
[10:31:27] <miss0r> bleh. somewhere along the way, I missed something. Those are not high precision
[10:32:18] <miss0r> Dinner time. I will be back later
[10:33:49] <gregcnc> most Precise spindle take odd collets, but that may be OK if you stick with 1/8" tooling
[10:35:59] <skunkworks> So... would a 9.5in-oz 60in-oz peak servo replace a 70 in-oz non-hybrid stepping motor?
[10:36:57] <skunkworks> (no magnet core in the stepping motor)
[10:38:02] <gregcnc> what is the application?
[10:38:09] <skunkworks> emco lathe
[10:38:34] <skunkworks> The servo runs it around with 12v applied.
[10:38:39] <archivist> best way to find out... try it
[10:38:42] <gregcnc> hah, i'm emailing some about the sme thing, but turn 120
[10:39:16] <archivist> seems well within sensible numbers
[10:39:22] <gregcnc> I think it will be pretty close
[10:39:26] <skunkworks> archivist, yah - it is 50% there. :). servos are mounted - just need some wiring and hal setup.
[10:39:37] <sync_> gregcnc: yeah, although all the sensible sizes are sold by them
[10:39:47] <skunkworks> I 'feel' like they will work :)
[10:39:57] <gregcnc> sync_ $$$$
[10:40:35] <skunkworks> http://electronicsam.com/images/matsuura/20170101_161125.jpg
[10:41:13] <skunkworks> aprox 2.5 reduction and 10tpi ball screw
[10:41:17] <sync_> not really gregcnc
[10:41:28] <sync_> something like 50€ per collet
[10:41:31] <skunkworks> (Without changing anything)
[10:42:20] <gregcnc> it's hard to determine what cutting feed forces are
[10:42:47] <gregcnc> power is low because feed rates on a lathe are low
[10:43:05] <sync_> I mean, sure, it is not cheap for a collet but it is not like you need a lot of them
[10:44:39] <gregcnc> the stepper delivers full torque all the time, while peak servo torque is for how long and how often?
[10:45:35] <sync_> peak torque usually is only limited by the heating in the winding
[10:46:09] <gregcnc> yes
[10:47:21] <gregcnc> how does that equate to machine performance is the question
[10:47:27] <archivist> stepper torque reduces with rpm
[10:47:41] <gregcnc> archivist, which is fine for rapids
[10:48:07] <archivist> often people want faster cutting , compromise
[10:49:02] <gregcnc> feed rates in lathe are slllllloooooowwwww
[10:49:30] <enleth> gregcnc: unless you want to do synchronized eccentric cuts
[10:50:04] <gregcnc> and you won't do any good at that unless the axis is very accurate
[10:58:52] <skunkworks> I get 282 lbs at peak torque
[10:59:14] <skunkworks> no - that isn't right
[11:03:30] <gregcnc> yeah emco spec 1kN or 225lb
[11:03:33] <gregcnc> force
[11:06:31] <gregcnc> skunkworks i'd measure the current once it's all running and see if you're averaging above rated current
[11:08:59] <skunkworks> sure
[11:10:51] <gregcnc> I was trying to figure out which fanuc servo Emco used in the 320 to compare to the steppers in the lower versions
[11:16:17] <ktchk> tutor for replace the kinematic of t he source code of 2.8 with the bipod.c
[11:22:46] <skunkworks> I get 471 lbs peak. (((60in-oz*2.5reduction*2*pi)/.1 lead)*.8% eff)/16 oz/lbs
[11:28:24] <gregcnc> if you haven't changed the screw or reduction, you're just comparing motor torque
[11:32:00] <gregcnc> So maybe emco wasn't running them at rated current?
[11:33:35] <skunkworks> the steppers where pretty crappy.. old school
[11:38:59] <Frank_6> any clue why my electrical cabinet smells funny and has white oxide powder on top of every din rail and screw (galvanized)
[11:40:28] <Loetmichel> hmm, i think i asked that a while back, but cant remember the answer: i just changed the Spindle coolant in my CNC mill. Any idea what to pump thru that china spindle to get the gross "biofilm" and the calcification out? preferably without damaging the aluminium cooling channels?
[11:40:52] <gregcnc> rated torque should yield something close to the quoted axis thrust. it works out for all the other emco machines I've checked.
[11:41:09] <Loetmichel> (should have put a bit more "car radiator additive" to it in the first place.)
[11:41:45] <Loetmichel> Frank_6: had any HCl standing around and open?
[11:41:57] <Loetmichel> or a car battery charging?
[11:42:10] <Frank_10> sorry whats hci
[11:42:19] <Frank_10> no battery
[11:42:22] <Loetmichel> muriatic acid
[11:42:37] <Frank_10> nope; besides the enclosure is closed
[11:42:52] <Loetmichel> that dosent help squat
[11:43:03] <Loetmichel> where air can go in acid vapors will
[11:43:03] <Frank_10> ohhh
[11:43:22] <Wolf_> rust converter spray (is muriatic I think)
[11:43:40] <Loetmichel> that white powder is most likely a zinc salt
[11:44:11] <Loetmichel> Wolf_: rust converter is usually phosphoric acid
[11:44:31] <Frank_10> now that i think about it; i did used some silicone caulk; and i didnt knew that it could rust metal; i got rid most of it but there is some leftover on the door
[11:44:51] <Frank_10> and i did used rust converter for the primer
[11:45:05] <Loetmichel> that would be vinegar then.
[11:45:08] <Loetmichel> also an acid
[11:45:10] <Frank_10> yes
[11:45:23] <Frank_10> should i worry about electronics? servo amps?
[11:45:39] <Frank_10> $#!+
[11:45:42] <Frank_10> $#!+
[11:45:46] <Frank_10> $#!+
[11:45:48] <Loetmichel> usually they are quite good insulated
[11:45:57] <Wolf_> just check the wire contacts
[11:46:18] <Wolf_> rest of it is mostly solid state so not much to worry about
[11:46:24] <Loetmichel> but it couldnt hurt to dismantle them and rinse them with demineralized water a few times
[11:46:47] <Loetmichel> and let them dry up for a week at a warm place before reassembling
[11:47:12] <Frank_10> yeah thats all good; only the galvanized (most probably crap quality) screws and din rails are showing that powder
[11:47:16] <Frank_10> and the ugly smell
[11:47:45] <Loetmichel> do you have high temperatures and high humidity in your shop?
[11:48:18] <Wolf_> or temperature cycling in the shop (cold/warm)
[11:48:23] <Frank_10> maybe; it isnt a tropical forest either.
[11:48:45] <Loetmichel> cycling would do the trick also, right
[11:49:41] <Frank_10> yep; it doesnt help that right now the cabinet sits without air ventilation; when i power uo the machine hopefully the fan helps a bit
[11:49:56] <Loetmichel> IF you are shure that its only the screws and rails: clean them with a wire brush, rinse with a pump spray and soapy water, then clean water, spray a slight coat of a thick oil on them, reassemble/repopulate the enclosure
[11:50:03] <Frank_10> wonder if this stupid powder is conductive
[11:50:20] <Loetmichel> and pack a big sack of decissant with indicator in it before closing
[11:50:39] <Wolf_> thats the problem in my shop, even in the summer overnight the temp inside will drop to ground relative because half the garage is below ground level, every morning durning the summer everything is wet
[11:51:20] <Loetmichel> Frank_10: it IS conductive once it gets wet
[11:51:39] <Loetmichel> IIRC all zinc salts are more or less water soluble
[11:52:10] <Frank_10> i dont think they will ever get wet; but in its powdery form i wonder
[11:52:25] <Loetmichel> they DO get wet
[11:52:38] <Frank_10> im so lucky that maybe some of it falls inside a servo driver and fuc&$ everything
[11:52:38] <Loetmichel> condensation when temperature cycles down over night
[11:53:18] <Loetmichel> "slightly wet" is enough to get that "blooming" quite conductive
[11:53:21] <Frank_10> that shitty. caulk
[11:53:55] <Loetmichel> use aquarium ("neutral") silicone caulk next time ;)
[11:54:25] <Wolf_> just clean it off, blow it out, oil things (LPS 2 or 3 like stuff )
[11:54:46] <Loetmichel> or keep well ventilated for a few weeks until the vinegar silicone is thoughly cured
[11:55:25] <Frank_10> its been like this for 2 months at least
[11:55:25] <Loetmichel> that caulk evaporates vinegar only while curing
[11:55:33] <Loetmichel> and it cures SLOW
[11:55:41] <Frank_10> no fan thou
[11:55:56] <Frank_10> kay ill put some fans for a a week or so
[11:56:13] <Wolf_> no fan needed, just leave it open to breath
[11:56:21] <Loetmichel> only helps if you can be sure that you get all the white stuff out first
[11:56:33] <Frank_10> the thing is the caulk is painted with enamel
[11:56:44] <Frank_10> why
[11:56:57] <Loetmichel> because that stuff is a water magnet
[11:57:20] <Loetmichel> and will continue to grow as long as it has a few crystals left
[11:57:28] <Loetmichel> <- in my experience at least
[11:57:47] <Frank_10> some salt will hopefully help
[11:58:17] <Loetmichel> salt will accelerate it.
[11:58:27] <Loetmichel> you need to neutralize it
[11:58:28] <Jymmm> vinergar will remove rust and laytex paint/caulk.
[11:58:31] <Loetmichel> not agitate ;)
[11:59:09] <Jymmm> Rinse off vinegar with water, then rinse with denatured alcohol to remove water.
[11:59:48] <Loetmichel> no tips though how i can clean my china spindle cooling channels without dismantling it?
[11:59:51] <Frank_10> i really wouldnt like to dissasemble the hole enclosure
[12:00:03] <Jymmm> Loetmichel: power washer
[12:00:18] <Frank_10> whats inside?
[12:00:42] <gregcnc> there is citric acid flush for cars
[12:00:51] <Loetmichel> Frank_10:
[12:01:05] <Loetmichel> [18:11] <Loetmichel> hmm, i think i asked that a while back, but cant remember the answer: i just changed the Spindle coolant in my CNC mill. Any idea what to pump thru that china spindle to get the gross "biofilm" and the calcification out? preferably without damaging the aluminium cooling channels?
[12:01:22] <Loetmichel> [18:11] <Loetmichel> (should have put a bit more "car radiator additive" to it in the first place.)
[12:01:48] <Jymmm> white vinegar works remarkably well
[12:01:51] <skunkworks> vinegar solution? works on coffee pots.. :)_
[12:02:21] <Jymmm> skunkworks: crushed ice and salt
[12:02:27] <Loetmichel> Jymmm: did use some 2 meters of hose filled with clean water today and then put an 8 bar air blowout pistol at the end
[12:02:42] <Loetmichel> quite a mess, but got a good part of the biofilm out
[12:02:49] <Frank_10> maybe you can use something stron if you can be sure that you dont damage the important parts like bearing seats and stuff
[12:03:09] <Loetmichel> cant use a power washer in the workshop
[12:03:18] <Loetmichel> too much electronics all around
[12:03:44] <Loetmichel> Frank_10: the chinese spindles have an aluminium heatsink inside the housing
[12:03:48] <Loetmichel> with very small fins
[12:03:53] <Jymmm> Loetmichel: try vinegar, it's not strong enough to cause damage, but soak for some time and it DOES do the job.
[12:04:21] <Loetmichel> no danger for the bearing tho, there is no connection from the cooling jacket to the motor inside
[12:04:33] <Loetmichel> Jymmm: will try, thanks
[12:05:04] <Jymmm> Loetmichel: Just check every 6 hours or so
[12:05:16] <Loetmichel> ( was gross to see the red/pink (from the car coolant additive) "flakes" flying out of the coolant hose :(
[12:05:59] <Jymmm> Loetmichel: I took a carpters square that was left outside for a year totally rusted pitted, 24 hours in vinergar got it down to bare metal again.
[12:07:31] <Loetmichel> Jymmm: problem is that these spindles are a material mix of Stainless, chromed hose connectors and aluminium heatsink inside
[12:07:37] <Loetmichel> with VERY fine fins
[12:08:57] <Jymmm> Loetmichel: Then soak and check every 2 hours. Unlike the more caustic solutions, vinegar is mild enough
[12:10:25] <Jymmm> Loetmichel: It's cheap enough for a gallon that if it doesn't work, no big deal.
[12:11:15] <Loetmichel> btw: $me has seen a vid of a "neighbor" (he lives less than 50km from me) lately who builds slingshots and crossbows for a hobby... MAN did i laugh at the comments about him wearing a tshirt. totally normal, i do the same when i am out no longer than an hour or two... -> https://www.youtube.com/watch?v=tbKGjRoSofA&t=36s
[12:11:41] <Loetmichel> Jymmm: does it attack plastics like in fountain pumps?
[12:12:22] <Loetmichel> if not i will simply fill the tank of the CNC with vinegar and start the pump for a few hours, that way i can clean the tank, the pump, the hoses AND the spindle all in one ;)
[12:13:01] <Jymmm> Loetmichel: Not that I've experianced. just do NOT use alcohol/denatured alcohol if you are concerned abotut plastics.
[12:13:24] <Jymmm> well, rubbing alcohol should be ok
[12:14:11] <Jymmm> but denatured alcohol will micro fracture acrylics, and a few other others
[12:16:39] <Jymmm> Loetmichel: You can always thin out the vinegar with water if you feel it might be too strong
[12:18:03] <jdh_> any suggestions for a really rigid linear stage for a Z axis with about 6 inches of travel?
[12:33:06] <Jymmm> jdh: ebay?
[12:33:52] <IchGucksLive> hi from a realy frezing germany
[12:34:52] <Jymmm> jdh: http://www.ebay.com/itm/Tusk-Direct-RT4-5-Heavy-Duty-Crossed-Roller-Linear-Stage-6-Travel-1016-lb-Load-/160970564591
[12:35:48] <IchGucksLive> Gn8 folks im firering the wood oven to keep headed
[12:39:50] <Loetmichel_> he is exaggerating
[12:40:03] <Loetmichel_> its only -5.5°C over here
[12:40:14] <Loetmichel_> not exactly "cold"
[12:40:39] <Jymmm> Loetmichel_: just because you are a polar bear, doens't mean that's not "cold"
[12:41:11] <Loetmichel_> oh, i am not.
[12:41:38] <Loetmichel_> when its -15°C outside i take the leather jacket on :-)
[12:49:08] <roycroft> it was 12 degrees when i woke up this morning
[12:49:20] <roycroft> that, combined with the overnight torrential downpour, finally melted off the rest of the snow
[12:50:05] <roycroft> we had snow on the ground for a week and a half - in the ~25 years since i've lived in eugene we've never had snow on the ground for more than 3-4 days before
[12:50:15] * roycroft is so glad that it's gone
[12:51:31] <gregcnc> all our snow in chicago melted and we had rain
[12:52:40] <roycroft> when i lived in chicago snow on the ground for weeks at a time was normal
[12:52:45] <roycroft> but that was in another lifetime
[12:53:36] <Loetmichel_> roycroft snow on the ground (and a foot deep, too) is pretty common here
[12:53:43] <Loetmichel_> for 2-3 months on end
[13:00:02] <roycroft> that's typical for chicago
[13:00:08] <roycroft> or, at least, it was when i lived there
[13:00:23] <roycroft> here it would snow every other year or so, and melt within a day or two
[13:00:27] <roycroft> until about five years ago
[13:00:36] <roycroft> with the acceleration of climate change we've been getting more snow than usual
[13:01:14] <roycroft> if this becomes the new norm i may be looking to move south again
[13:01:23] <roycroft> sadly, california would be the next stop
[13:01:40] <Loetmichel_> honestly: i like it cold
[13:01:40] <roycroft> and the regulatory climate there makes it difficult to run a business
[13:01:49] <roycroft> i like how it used to be here
[13:01:54] <Loetmichel_> when its cold outside you can simply run a bit and get war,
[13:01:56] <Loetmichel_> warm
[13:02:01] <roycroft> when i was in the mood for cold and snow, i would drive for an hour and be up in the mountains
[13:02:04] <Loetmichel_> when its hot you only can sweat...
[13:02:08] <roycroft> when i got tired of it i would drive back down
[13:02:35] <roycroft> we are seeing warmer summer temperatures here now, too
[13:02:55] <roycroft> we used to hit 40 degrees once every few years
[13:03:04] <roycroft> now it gets up to 40 several times every summer
[13:03:44] <Loetmichel_> 40°C or F?
[13:05:51] <roycroft> c
[13:06:13] <Loetmichel_> thats pretty warm
[13:06:26] <roycroft> if i'm going to use archaic units i'll stipulate them at the time :)
[13:06:33] <roycroft> it's bloody hot
[13:07:24] <roycroft> i like this new drill a lot
[13:07:42] <roycroft> it has a switch to change from drill mode to screwgun mode to impact mode
[13:08:11] <roycroft> with my old ones i could set the torque to infinite for drilling and dial it down for driving screws, but i'd have to change the setting each time
[13:08:35] <roycroft> with this one i can dial in the screw torque, and then just switch it back and forth between that and drilling
[13:09:06] <roycroft> i am old and can't remember what the setting is all the time, so having the drill remember is a big help :)
[13:09:43] * Loetmichel_ once had a compressed air "nailer" that could shoot special screws that had a thread like a pine cone
[13:09:46] <roycroft> i also like that i can't stall it out no matter how hard i push it
[13:09:51] <Loetmichel_> goes in, never goes out
[13:09:56] <Loetmichel_> until you SCREW it out
[13:10:03] <Wolf_> oh cool
[13:10:10] <roycroft> i bet you can split wood with that
[13:10:21] <roycroft> mostly unintentionally :)
[13:10:26] <Wolf_> I use ring nails, they don’t come back out
[13:10:31] <Loetmichel_> if its a 1 by 2: sure
[13:10:40] <Loetmichel_> everything thicker will probably be ok
[13:10:57] <roycroft> i don't use nails for much of anything these days
[13:11:10] <roycroft> although i do use them for framing
[13:11:20] <roycroft> nothing beats a big nail gun for framing
[13:11:24] <Loetmichel_> Wolf_: the thing with these screws is that you can "nail" them in, but screw them out just like a normal drywall screw
[13:11:41] <Loetmichel_> so "best of both worlds"
[13:14:43] <roycroft> http://eugene.craigslist.org/tls/5908150442.html
[13:14:47] <roycroft> is it scrap or does it have potential?
[13:15:13] <roycroft> the price is right
[13:15:18] <roycroft> $750 for the surface grinder
[13:15:31] <roycroft> ~$25k for the extension to my shop so i can have room for it
[13:15:55] <Loetmichel_> hihi
[13:15:57] <roycroft> so only $25,750 plus whatever it costs to restore
[13:16:26] <roycroft> i can probably build the extension for half that
[13:16:38] <roycroft> which makes it an even better deal!
[13:18:46] <Loetmichel_> roycroft: "error, no space left on device" ;)
[13:18:53] <Loetmichel_> thats a problem we all have ;)
[13:21:23] <roycroft> indeed
[14:26:30] <cnc> hi can i create a mashine with x y and A the wizard dont have this option should i create a lathe and add 1 axis or is it better do make a mill mashine with a rotary Y
[14:34:49] <Wolf_> if its a mill, mill with A
[14:37:20] <cnc> no lathe
[14:37:38] <cnc> with a C axis
[14:37:39] <Wolf_> are you building a lathe or a mill?
[14:38:13] <cnc> Lathe with a C axis the spindel is Spindel an C after M code
[14:39:38] <cnc> do u know what i mean ?
[14:40:46] <Wolf_> I don’t know lathe stuff, someone else here should be able to help
[14:41:40] <cnc> when i add a mashine axis in linux cnc is it only in the .ini file ?
[14:42:18] <cnc> so i can change the koordinates in xzc and add a axis
[15:02:04] <enleth> pcw_home: have you ever considered changing the connector layout diagrams in Mesa card docs so that they actually list all pin functions individually, with the diagram scaled to full page size? For both 7i77 and 7i76e, I cropped the diagram out of the manual (and rotated it 90deg, then scaled up), removed the descriptive text and printed that, then annotated each pin by hand on the printout
[15:02:21] <enleth> pcw_home: only then it was actually convenient to work with
[15:03:20] <enleth> pcw_home: consider the fact that on the diagram, as it's positioned now, most of the screw terminals have the first pin closer to the bottom of the page, while the pin function list is obviously ordered from top down
[15:06:39] <enleth> which means that you need to read the relevant part of the list, then mentally flip the order before taking a look at the diagram
[15:12:37] <enleth> pcw_home: obviously (I think?) it would be easier to have a version of the diagram that filla a whole page with minimal margins and describes individual pin functions on the screw terminals
[15:20:16] <enleth> right now there are even no divisions between pin groups marked on those diagrams
[15:27:53] <FloppyDisk5_25> that's part of the challenge...
[15:28:08] <Frank_6> anyone knows how much current can the 7i76 inputs take for example for a 24vdc psu and a servo sending servo-ready and alarm outputs my servo diagram for those pins says that it can actuate up to a 50mA relay i was wondering if i could just wire directly those servo outputs to the mesa card
[15:34:03] <FloppyDisk5_25> Servo Ready and alarm outputs are usually pretty low current output. You should be able to wire directly. I looked at the 7i76 manual and it talked about 10k ohm resistors.
[15:34:19] <Frank_6> i understand they have a nominal resistance of 10K ohms, it would mean that with a 24vdc psu it uses 25mA? aprox
[15:34:41] <FloppyDisk5_25> ohms law.
[15:34:43] <FloppyDisk5_25> yup
[15:34:44] <Frank_6> V/R=I
[15:34:45] <Frank_6> :D
[15:34:59] <Frank_6> cool thanks for the sanity chekc
[15:35:53] <FloppyDisk5_25> Yeah - based on that 10k ohm resistor, you'll have the 25mA coming from your servo, you should be fine...
[15:51:00] * MacGalempsy is making good progress on wiring back up the mill
[15:59:18] <MacGalempsy> jeez. my buddy just told me that there were over 150 applications recieved for the position I am trying to get
[15:59:35] <Tom_itx> ha
[15:59:50] <MacGalempsy> yeah. wow!
[15:59:57] <MacGalempsy> all 5-20 year ppl
[16:00:15] <Tom_itx> that many out of work?
[16:00:24] <MacGalempsy> and that is just OKC
[16:00:55] <Tom_itx> qualified applicants?
[16:01:32] <Tom_itx> or just applicants
[16:01:44] <MacGalempsy> idk. he's supposed to find out if I made the cut
[16:02:17] <MacGalempsy> i havent smoked in years, but this kind of stuff makes me want to buy a pack!
[16:03:07] <Tom_itx> what industry?
[16:03:18] <MacGalempsy> oil and gas geologists...
[16:03:28] <Tom_itx> ahh
[16:03:47] <Tom_itx> i know one here that says it's kinda bleek for him right now
[16:03:48] <MacGalempsy> well, the title was for geoscientist, so I bet there are a bunch of geophysicists in that bunch too
[16:04:32] <MacGalempsy> I think they are wanting to push a 3 rig program, so that would mean 2 geols and 1 geowizkid
[16:06:10] <MacGalempsy> they made an acquisition for $1.2B and need the team together by 2/15
[16:07:30] <Tom_itx> they've been blamed for the earthquakes of recent down there
[16:08:13] <MacGalempsy> yeah, this area is south of that.
[16:10:21] <MacGalempsy> this other company I have been talking to is trying to get money together to make their 2 rig program into a 6 rig program. if that goes thru then I shouldn't even have to interview
[16:11:42] <MacGalempsy> it makes sense that they had that many apps. I heard there are over 10k geoscientists out of work in houston alone!
[16:14:38] <Tom_itx> maybe they should move to the middle east
[16:14:59] <MacGalempsy> i saw a position in Iraq for $800/day, but the wife said no
[16:15:30] <Tom_itx> i know someone that went over to do HVAC work for the govt over there..
[16:15:32] <Tom_itx> good pay
[16:15:54] <Tom_itx> dodge an occasional bullet
[16:16:08] <roycroft> i would not work in iraq for $8000/day
[16:16:25] <MacGalempsy> if I could pack heat, it would be worth the risk :)
[16:17:13] <MacGalempsy> that $800 is only for wellsite work, a real position would probably closer to $1500/day
[16:17:25] * roycroft will stay in oregon
[16:18:00] <MacGalempsy> its probably safer for the world roycroft :P
[16:18:54] <roycroft> i'm not a dangerous person, i don't think
[16:20:58] <sync_> sounds like fun MacGalempsy
[16:21:13] <XXCoder> most dangerous game
[16:21:18] * roycroft gets back to lacing cables
[16:21:25] <roycroft> it's my meditation :)
[16:21:58] <MacGalempsy> the most dangerous game I lived was daily commute in the SF Bay Area while living in East Oakland
[16:22:52] <Wolf_> I worked in west side of baltimore…
[16:30:18] <MacGalempsy> how long ago was that Wolf_?
[16:30:39] <Wolf_> same time they were filming The Wire lol
[16:31:08] <Wolf_> 98-2000
[16:42:08] <Deejay> gn8
[17:02:24] <enleth> what's going to be worse for a 7i76E - Realtek 8139 (100Mbit/s, the most ubiquitous piece of networking shit on the planet) or a Broadcom BCM5751?
[17:02:41] <CaptHindsight> anyone have or use the Dewalt Band Saw (120V) not the L-Ion version?
[17:03:07] <CaptHindsight> have only had success with the Milwaukee's so far
[17:03:47] <MacGalempsy> did you try any online reviews?
[17:04:04] <CaptHindsight> no, I only ask in here :)
[17:05:28] <Wolf_> no dewilt tools here
[17:06:16] <MacGalempsy> I agree, we are the world authorities on everything around here'
[17:07:52] <CaptHindsight> no Dewalt here either
[17:08:11] <Wolf_> my milwaukee are still kicking, one of them is well over 16yrs
[17:08:12] <CaptHindsight> saw one on craigslist, looks new
[17:08:23] <MacGalempsy> i got a construction foreman buddy who uses a lot of dewalt, let me ask him
[17:08:53] <CaptHindsight> I have Milwaukee tools from the 80's still kicking
[17:09:00] <CaptHindsight> they usually die from abuse
[17:09:29] <CaptHindsight> 12" long 1" dia masonry bit in 1/2" hammer drill etc
[17:09:39] <MacGalempsy> they are basically black and decker industrial
[17:09:53] <CaptHindsight> figures
[17:10:16] <Wolf_> 12” long 1” ship auger is how i broke the chuck of my m18 drill lol
[17:10:19] <CaptHindsight> I tried the HF band saw for a few hours and returned it
[17:10:32] <MacGalempsy> my uncle use to be a sales rep for them. but we have never used the bandsaw
[17:11:04] <CaptHindsight> started slipping after 20 or so cuts into steel channel ~1"x 2"
[17:11:54] <CaptHindsight> I just broke my right angle 1/2" milwaukee
[17:11:59] <MacGalempsy> danm. might as well find a used horizontal bandsaw for the price of 2 dewalt portables
[17:13:07] <CaptHindsight> $100 for a used Milwaukee deep cut
[17:13:19] <CaptHindsight> think they are $350 new
[17:13:50] <MacGalempsy> do they make carbide blades for those?
[17:13:57] <sync_> you can just weld your own
[17:13:59] <MacGalempsy> or would you have to get one custom made?
[17:14:13] <sync_> clamp the blade to a piece of copper and tigweld
[17:14:26] <CaptHindsight> http://chicago.craigslist.org/sox/tls/5961969669.html $250 doesn't look too bad
[17:14:53] <Wolf_> https://www.amazon.com/Milwaukee-6232-6N-Deep-Band-Case/dp/B001SESFTK/ref=sr_1_5?ie=UTF8&qid=1484779494&sr=8-5&keywords=deep+cut+bandsaw
[17:15:09] <MacGalempsy> yeah. now thats what im talking about
[17:15:26] <MacGalempsy> and you dont have to throw your back out holding the damn saw
[17:15:29] <sync_> the only thing that sucks about the cheap ones is the unrealistically far distance from the vise to the blade
[17:15:53] <CaptHindsight> wow only $250 new
[17:15:57] <CaptHindsight> forget used
[17:16:05] <Wolf_> I like my wilton, until I need to move the damn thing
[17:16:29] <MacGalempsy> lol
[17:16:40] <MacGalempsy> guess not a great deal
[17:17:04] <CaptHindsight> http://chicago.craigslist.org/wcl/tls/5962893768.html $500 or best
[17:17:23] <MacGalempsy> 3 phase
[17:17:51] <CaptHindsight> heh just came from the electrical supply store....
[17:17:53] <MacGalempsy> anything used, you should take a piece to make a test cut
[17:17:53] <gregcnc> 3 phase more better
[17:18:08] <MacGalempsy> if you got it
[17:18:23] <CaptHindsight> I asked if they had any 3phase 120/240 squared d breakers in stock
[17:18:27] <gregcnc> vfd to the rescue
[17:18:34] <CaptHindsight> he asked me 3 phase or 3 pole?
[17:19:08] <gregcnc> did you ask what the difference was?
[17:19:09] <MacGalempsy> ah good point gregcnc. that wouls be a sweet setup
[17:19:12] <CaptHindsight> I said it's the same thing and he muttered off and came back with a 60a vs a 30a
[17:19:32] <MacGalempsy> variable speed bandsaw
[17:19:39] <CaptHindsight> gregcnc: it was the asshat at Steiner
[17:19:40] <MacGalempsy> digital variable speed
[17:20:01] <CaptHindsight> I just turned around and said I'd look for a supplier that has a clue
[17:20:01] <gregcnc> lol there are all kinds
[17:20:41] <gregcnc> i might put a 3 phase and vfd on my old delta 14"
[17:20:46] <CaptHindsight> he also asked if it was 360V
[17:20:57] <CaptHindsight> I asked him if he is in Europe
[17:21:22] <gregcnc> this guy has been there for a while?
[17:22:20] <CaptHindsight> first time I have seen him but he was giving the customer in front of me shit about his 3-p twist lock connector
[17:22:49] <CaptHindsight> like the customer was clueless
[17:23:04] <MacGalempsy> lol. what a clown
[17:23:13] <gregcnc> that's just bad for business
[17:23:39] <CaptHindsight> I'll get his name and call ElK Grove and complain about they help they have
[17:29:35] <cnc_> hey guys how can i build a lathe with a A axis ?
[17:30:04] <cnc_> The A axis is a motor thet connects by a M code to the Spindel
[17:31:21] <MacGalempsy> I think you can start out by watching about 40hrs of youtube videos on lathes
[17:31:34] <gregcnc> a axis?
[17:31:49] <roycroft> is this to index the spindle?
[17:31:55] <roycroft> or is it for spindle control?
[17:32:36] <roycroft> spindle speed/direction, that is
[17:32:59] <cnc_> C
[17:33:12] <cnc_> sorry in the Wizard is only A
[17:34:02] <CaptHindsight> MacGalempsy: https://www.youtube.com/watch?v=mzWMdZZaHwI&list=PL3D4EECEFAA99D9BE I suggest watching this series as well
[17:34:59] <MacGalempsy> tank you velly much
[17:35:32] <cnc_> i plug a step motor to the Spindel its a lathe and can türn the cuck for my driven tool
[17:35:54] <cnc_> but in the wizard i cant add a C axis to a lathe
[17:36:23] <gregcnc> C axis is not in the wizard, it's an advanced configuration
[17:36:31] <MacGalempsy> cnc_: do you have a picture of your machine?
[17:36:44] <cnc_> tomorrow
[17:36:56] <cnc_> at the moment
[17:37:09] <gregcnc> is this a retrofit?
[17:37:11] <cnc_> i try to config the linuxcnc
[17:37:23] <MacGalempsy> very much not trying to be rude, but a little bit of research on your end will help with basic understanding of the machine you are trying to build
[17:37:25] <cnc_> no its a selfmade :)
[17:37:48] <cnc_> ok
[17:38:59] <gregcnc> it has to be setup to switch between regular turning, and C axis
[17:39:18] <gregcnc> there is some discussion on the forums
[17:39:31] <cnc_> ok i will read thanks
[17:39:50] <gregcnc> i've looked into it, but that is all
[17:40:55] <CaptHindsight> https://www.menards.com/main/tools-hardware/power-tools-accessories/power-saws-accessories/9-performax-band-saw/p-1444443006811-c-9082.htm?tid=5524112142764199677 will this work as a portable if I add a car battery and ac inverter?
[17:42:50] <MacGalempsy> CaptHindsight: that video series is starting off great. and it is actually 40 hrs!
[17:43:20] <gregcnc> what are you learning?
[17:43:49] <MacGalempsy> Mechanical - Design of Machine Elements - Design Philosophy
[17:44:26] <MacGalempsy> learning how to design a youtube series that will make me a millionaire
[17:45:29] <CaptHindsight> huh, mine was "How to loose weight and earn millions while you sleep"
[17:49:26] <CaptHindsight> anyone been appliance shopping lately? They sucker er eh charge $100-300 extra for stainless steel skins on the fronts
[17:50:07] <Wolf_> good part is they show damage very well, so scratch/dent are cheap :D
[17:51:04] <gregcnc> macgalempsy maybe you like playing with toys ?https://www.youtube.com/user/Disneycollectorbr
[17:51:54] <MacGalempsy> hehe. that would be cool. maybe make cute hedgehog videos
[17:52:05] <gregcnc> http://www.huffingtonpost.com/2015/02/05/youtube-stars-money_n_6549906.html
[17:52:19] <CaptHindsight> some might have been plastic with maybe 40ga SS foil glued on
[17:52:39] <gregcnc> the cheaper ones look stainless
[17:54:57] <CaptHindsight> whats a reversible refrigerator? Do they cool as well as heat food?
[17:56:03] <gregcnc> mac, design a reversible microwave and you'll be rich
[17:56:34] <MacGalempsy> nah, I dont want to sell a product
[17:56:38] <gregcnc> capt you probably turn it inside out to change the color
[17:56:51] <MacGalempsy> just get ppl to watch my videos
[17:58:24] <cnc_> http://linuxcnc.de/index.php?page=shop.product_details&category_id=48&flypage=flypage.tpl&product_id=42&option=com_virtuemart&Itemid=171 can i use this for a mill mashine analog inputs sin encoder 3 axis and spindel analog
[17:59:22] <CaptHindsight> http://chicago.craigslist.org/nwc/atq/5955350182.html Kelvinator Moist Master Refrigerator Keeps your soggy food fresher for longer
[18:00:10] <MacGalempsy> anyone have experience with this brand of router? http://tulsa.craigslist.org/tls/5959157936.html
[18:01:23] <gregcnc> This Monty Carlow keeps showing up in my machine searches https://chicago.craigslist.org/nwi/bar/5934821642.html
[18:02:01] <CaptHindsight> from the really ugly years
[18:02:18] <CaptHindsight> the hoods were 12ft long :)
[18:03:18] <gregcnc> hah yeah, and this https://chicago.craigslist.org/chc/hvo/5963770408.html
[18:03:19] <CaptHindsight> MacGalempsy: 1/2 price http://www.generalcnc.ca/the_icarver1
[18:03:54] <MacGalempsy> that seems fair, but not really looking for myself
[18:04:08] <MacGalempsy> that looks about big enough to do a guitar top
[18:04:22] <MacGalempsy> well maybe a mandolin
[18:04:44] <malcom2073> Gregcnc: that Monty car is lowwww
[18:04:47] <CaptHindsight> they aren't built too bad
[18:04:54] <malcom2073> Haha
[18:05:07] <CaptHindsight> I could build from used ebay parts for better and less
[18:05:22] <MacGalempsy> that is the second one Ive seen on CL in the last few days. the other one was in Dallas and they wanted $4k
[18:06:11] <malcom2073> I love used eBay parts for cheap CNC routers
[18:06:14] <MacGalempsy> that is what devtron and I were just discussing in google hangout
[18:06:39] <malcom2073> Mac, you're smart enough to build your own from parts
[18:07:20] <MacGalempsy> I'm more interested in getting a lathe next, but doing a generic CNC search brings up more
[18:07:37] <malcom2073> I want a CNC lathe, my manual is so limiting
[18:07:50] <MacGalempsy> lathe and bar feeder
[18:08:21] <gregcnc> are you still looking for somethign for that tube part?
[18:08:35] <malcom2073> Gonna make a ton of widgets?
[18:08:39] <CaptHindsight> MacGalempsy: what xy do you need?
[18:09:05] <MacGalempsy> yeah. I keep thinking it will be on the back burner.
[18:09:32] <MacGalempsy> the length is only 12" overall, so like a 20" bed. and the diameter is 1"
[18:10:03] <MacGalempsy> I figured once I get this mill back up and running, I might try using the 4th axis to do the parts
[18:10:38] <malcom2073> What part you making?
[18:11:06] <MacGalempsy> its almost wired back up, tomorrow it should be ready to program. still need 2 2pole relays so I can reverse the turret
[18:11:29] <MacGalempsy> it is the lift struts for the FJ40 land cruiser
[18:12:04] <MacGalempsy> the kind with the lift gate, once company sells refurbs for like $600 a set
[18:12:34] <malcom2073> Lol nice.
[18:12:47] <MacGalempsy> after pricing out the parts for the cad design, the materials came out to $30 plus the hydraulic lift
[18:13:47] <MacGalempsy> http://www.sor.com/cat134.sor
[18:14:10] <Wolf_> $600 for a set? of gas springs for a hatch?
[18:14:11] <MacGalempsy> $665 now
[18:14:35] <Wolf_> $200 core charge included
[18:14:43] <MacGalempsy> so $465.
[18:14:51] <malcom2073> That's refurb though, people pay for the name.
[18:14:59] <malcom2073> Aftermarket would be like 1/2 price
[18:15:14] <MacGalempsy> if you make them identical, who knows the difference?
[18:15:33] <MacGalempsy> the ones I have are not branded anywhere on the part
[18:16:48] <MacGalempsy> I would sell just the lifts, not the brackets
[18:16:53] <gregcnc> originally springs?
[18:17:14] <MacGalempsy> the mod is to take the springs out and use a NAPA part to replace them
[18:17:32] <MacGalempsy> even with the spring, the thing falls and cracks you in the head
[18:17:49] <MacGalempsy> it has those flange nuts, but they aren't so great
[18:17:55] <gregcnc> there is some finishing time involved for a new part, plating
[18:18:54] <MacGalempsy> I figured each of the 3 major shops would buy 20 each to make it worth it, so 60 sets.
[18:19:35] <MacGalempsy> so it would only be worth $9k
[18:19:45] <MacGalempsy> maybe ship some to eur and aussie
[18:20:57] <gregcnc> spinners man... https://www.instagram.com/explore/tags/fidgetspinner/
[18:22:48] <gregcnc> and tops https://www.instagram.com/explore/tags/spinningtops/
[18:23:19] <MacGalempsy> the other day I was cooking dinner and thought it would be cool to have a faucet extension that measured out volume
[18:23:31] <gregcnc> like tha bar taps?
[18:23:36] <MacGalempsy> forget the measuring cups, just dial it in
[18:32:36] <enleth> hm. does hm2_pci work with RT-Preempt?
[18:39:16] <enleth> and most importantly - *is* there actually any recent documentation on rt_preempt with linuxcnc?
[18:39:54] <JT-Shop2> I "think" preempt works with both pci and ethernet cards
[18:40:15] <JT-Shop2> the docs are the most recent documentation
[18:40:20] <Frank_6> jt
[18:40:27] <JT-Shop2> frank
[18:40:33] <Frank_6> hello sir
[18:40:46] <Frank_6> i wanted to ask you just a little question if i may
[18:41:23] <enleth> JT-Shop2: problem is, the docs are peppered with stale statements regarding what's been merged, what's "in master only" and so on
[18:41:56] <Frank_6> you said the other day that you used a relay to send 0v to the servodrives, you use one relay for each servo or just 1 output from mesa card to 1 relay (1pole) to switch every servodrive=
[18:42:24] <enleth> JT-Shop2: as in, looks like no one has been updating them since 2.6 and some content has been written with little regard for the fact that it's going to be outdated with regard to the code pretty soon
[18:42:54] <Frank_6> = equals-->question mark :D
[18:48:29] <JT-Shop2> just one relay for all the drives
[18:48:46] <roycroft> one relay for them all
[18:48:49] <roycroft> one relay to drive them
[18:48:53] <JT-Shop2> enleth: I update them all the time
[18:50:09] * JT-Shop2 wanders inside to the cocina and puts his chef hat on
[18:50:37] <enleth> well, OK, the *wiki* has lots of stale articles
[18:50:48] <JT-Shop2> that is up to the users to maintain
[18:51:43] <JT-Shop2> say goodnight Gracie
[18:52:07] * JT-Shop2 waits till riders on the storm is over...
[18:52:12] <Frank_6> thanks jt
[18:52:42] <JT-Shop2> yea frank pick any axis and connect that enable to all the axes drives
[18:53:22] <Frank_6> thumbs up! what i was thinking. 1 pole relay right?
[18:53:33] <JT-Shop2> I usually pick axis_0 for some unknown reason
[18:53:37] <JT-Shop2> yea
[18:53:37] <enleth> do the actual docs even include an rt_preempt guide?
[18:53:39] <Frank_6> hehe
[18:53:53] <JT-Shop2> enleth: did you look?
[18:54:23] <JT-Shop2> time to cook...
[18:55:42] <enleth> in the process of doing that, I might just now have found it
[18:56:54] <pfred1> seek and ye shall find
[18:57:31] <enleth> OK, the relevant info is there under "Getting LinuxCNC", but it's not terribly obvious that this page is the right place to look if you already *have* LinuxCNC installed and working, and just need to switch from rtai to rt-preempt
[19:00:32] <pfred1> enleth just need to switch from rtai to rt-preempt?
[19:00:41] <pfred1> that's some just
[19:01:10] <pfred1> this isn't a light switch that we're talking about here
[19:01:30] <enleth> pfred1: not much of a choice if I want to use hm2_eth
[19:02:26] <enleth> OTOH it wasn't really difficult once I knew the name of the relevant kernel package and linuxcnc-uspace
[19:04:40] <enleth> it took all of 5 minutes including a reboot
[19:05:05] <enleth> and everything works as far as I can see, testing the Bridgeport right now
[19:54:02] <malcom2073> The majority of what I do on my CNC mill: https://www.youtube.com/watch?v=SP_ioBM1GJ8
[19:54:13] <malcom2073> Make sure the holes are in the right spot so I don't have to egg them out to make the bolts thread nicely
[19:59:00] <pfred1> malcom2073 when I made my collet holder yesterday I had my CNC scribe the center lines then I drilled them out by hand
[19:59:10] <pfred1> it worked good
[20:05:08] <malcom2073> Nice
[20:05:13] <malcom2073> I suck at hand drilling, even on a drill press
[20:05:40] <malcom2073> And I'm pretty bad at hole transfer, so combine the two and stuff never lines up :)
[20:09:18] <pfred1> when I really want holes to line up then I drill parts together
[20:10:35] <malcom2073> I've done that, I've also clamped parts together to drill through
