12:01 AM veegee: Hmm, you know the hand wheel on every vertical mill ever? How do you get the handle off?
12:06 AM veegee: Like _just_ the handle that spins freely
12:06 AM veegee: There's some dirt grinding inside. Is it a press fit or something? Do I need to use a gear/bearing puller?
12:37 AM veegee: https://galleryplus.ebayimg.com/ws/web/233288665473_1_5_1.jpg
12:37 AM veegee: How do I separate the left side from the right side?
12:38 AM XXCoder: use 2 tools
12:38 AM XXCoder: in least think so maybe not
12:46 AM _unreal_: sup
12:46 AM XXCoder: not much you?
12:46 AM XXCoder: i wanted to play with laser engraver but feeling lazy
12:47 AM _unreal_: hum
12:47 AM _unreal_: I lost my entire night
12:48 AM _unreal_: """" ish friend """ said he wanted to go bowling. so I agreed. only to find that he was SUPER piss drunk
12:48 AM _unreal_: and wanted to go to the beach. and coome to find out smoke a joint. I'm like WTF get that shit out of my car....
12:49 AM _unreal_: 1:40am and I only just got home
01:45 AM CaptHindsight: https://www.nbcchicago.com/news/local/chicago-coronavirus-patient-receiving-treatment-at-hoffman-estates/2207002/
01:45 AM CaptHindsight: great a 20 minute drive
01:50 AM veegee: Meh it'll be fine
01:50 AM veegee: They're taking the quarantining thing seriously this time
02:01 AM Deejay: moin
02:15 AM gloops: no slot for a screwdriver in the end of the stud veegee
03:01 AM gloops: might give one of these a shot next week
03:01 AM gloops: https://www.ebay.co.uk/itm/CNC-SPRING-LOADED-DRAG-ENGRAVER-TOOL-COMPLETE-KIT-7MM-COLLET-DIAMOND-TIP/274223758003
04:20 AM Tom_L: morning
05:21 AM XXCoder: would loovr to visit https://www.youtube.com/watch?v=_ziP_4pouN8
05:21 AM XXCoder: warning, stbilized video tho
06:34 AM jthornton: morning
06:35 AM XXCoder: yo
07:11 AM jthornton: OpenBox is installed :)
07:11 AM XXCoder: i forgot, whats you using rpi for?
07:12 AM jthornton: this one controls the chicken coop
07:12 AM XXCoder: oh yeah
07:32 AM jthornton: all right I have all the preliminary setup work done static IP set hostname set auto login now for the real test lol
07:35 AM XXCoder: :) hope it goes well
07:35 AM XXCoder: goibng to bed
07:38 AM jthornton: night
07:57 AM Elmo40: _unreal_, I am confused. Why spend the time to make these drive nuts and mess with a stainless threaded rod when you could have bought an inexpensive ball screw and proper blocks?
07:57 AM Elmo40: https://www.aliexpress.com/item/32904832997.html
07:58 AM Elmo40: 2m long 16mm diameter with both end blocks and ballnut. $167
07:58 AM Elmo40: cut to length. if you don't need 16mm there are even less expensive options.
09:23 AM jymmmm: Morning folks
09:24 AM net|: https://github.com/tecan/emscripten-projects/tree/master/qtProjects/Qt-SDL
09:24 AM net|: was able to get them working together yesterday from found code
10:51 AM net|: oops forgot the ui file
11:06 AM unterhaus: I was always a bit skeptical of grbl, but now you can get the arduino, drivers, etc for $20 it seems like it might be pretty useful
11:06 AM unterhaus: I always wanted to build a cnc wheel truing stand, I might just do it now
11:08 AM Tom_L: is grbl actively being developed?
11:09 AM Tom_L: looks like it's been about 5 yrs
11:10 AM unterhaus: new release 1.1 in august 2019. They split off the repository
11:11 AM Tom_L: that must be their old site
11:13 AM unterhaus: I see where you get the 5 years though, I'm not sure I understand what's going on
11:14 AM Tom_L: doesn't look like any major enhancements other than 2 motor gantry
11:14 AM unterhaus: I have another project where I'm thinking about moving stuff around by just sending it gcode
11:14 AM _unreal_: Elmo40, I need a custom size
11:14 AM unterhaus: they really don't have much room for enhancements
11:15 AM Tom_L: ?
11:15 AM Tom_L: port it to arm
11:15 AM unterhaus: it has been ported to bigger arduinos
11:15 AM unterhaus: no longer called grbl
11:15 AM Tom_L: well that's confusing
11:16 AM _unreal_: Elmo40, I may go ballscrew for Z
11:17 AM unterhaus: like machinekit vs linuxcnc
11:18 AM unterhaus: there is a grbl mega, haven't looked into it yet because I think grbl will work
11:19 AM Tom_L: machine kit grew out of a diversity of opinion
11:19 AM unterhaus: so did all the children of grbl
11:20 AM unterhaus: too bad the 4th axis has to be ganged on grbl, seems like independent action would be easier
11:23 AM _unreal_: unterhaus, not enough cpu cycles for 4th
11:24 AM _unreal_: as I recall there is a custom grbl build that has the 4th as an axis and not a clone output. never found it. never really looked. and I dont know what grbl sneder could control it
11:33 AM unterhaus: I don't think I would use grbl for a cnc, so probably have my own sender
11:37 AM unterhaus: hm, the mega cnc kits are only $30 and come with a display
11:38 AM unterhaus: oh well, stop thinking up new projects and go finish some
11:49 AM _unreal_: Thats what I'm trying to do...
11:49 AM _unreal_: just finished soldering a few more parts on to my servo controllers
11:49 AM _unreal_: :/
11:49 AM _unreal_: still waiting on a bunch though :(
11:50 AM _unreal_: including the @#$@#$@# opamps to drive them.....
11:50 AM _unreal_: I found a cheap location and they fucked up and now they are not responding BUT they did refund the money for the opamps at least
12:37 PM unterhaus: lunchtime. Went down the rabbit hole, now I see there are smoothie board clones for cheap
01:11 PM unterhaus: any of the mini pc known to work okay with rt linux? Celeron processor
01:22 PM unterhaus: I'm leaning towards replacing my mesa pci board with a mesa ethernet
01:23 PM Tom_L: why?
01:23 PM _unreal_: ditto
01:23 PM _unreal_: and if you are what kind is it?
01:24 PM _unreal_: and are you in the USA?
01:24 PM Tom_L: 7i92 probably
01:24 PM _unreal_: I'm slightly interested do to building ve7it's servo drivers http://ve7it.cowlug.org/dspic-servo.html
01:24 PM _unreal_: that take quadrature inputs
01:25 PM _unreal_: I need more bandwidth then the parport
01:25 PM unterhaus: 5i20 or something like that?
01:25 PM _unreal_: speaking of bandwidth nvz any progress?
01:25 PM _unreal_: unterhaus, if you do swap do you still have a need for that card?
01:26 PM _unreal_: and does it support quadrature outputs?
01:27 PM unterhaus: it's one of the 50 pin fpga cards.
01:28 PM Tom_L: _unreal_, i'm pretty sure any of them can
01:28 PM _unreal_: Thats what I would figure but got to ask
01:28 PM unterhaus: what is a quadrature output used for?
01:29 PM unterhaus: as far as why, I'm tired of dealing with space issues in my control cabinet
01:30 PM _unreal_: unterhaus, I dont know much about it but its more or less still just step/direction
01:30 PM unterhaus: is that a hostmot option?
01:31 PM unterhaus: I guess I have seen stepper drives with quadrature input, it's like having both step/dir on both inputs
01:31 PM _unreal_: unterhaus, I believe its just how it sends the signals
01:31 PM _unreal_: instead of having one wire step and one wire direction
01:31 PM _unreal_: it sends the same encoder signals as a quadrature encoder
01:32 PM _unreal_: so 00, 01, 11, 10
01:32 PM pcw_home: Hostmot2 stepgens support step/dir, quadrature and CW/CCW modes
01:32 PM _unreal_: I could be wrong
01:33 PM _unreal_: but that would make sense
01:33 PM unterhaus: huh, I think in my misguided ebay buying spree days I got a CW/CCW amp
01:33 PM _unreal_: ?
01:33 PM _unreal_: not sure what you mean
01:34 PM Tom_L: the cards can change their arrangement depending on the bit file you load into them
01:34 PM unterhaus: I used to buy just about anything servo motor related if it was cheap enough
01:34 PM unterhaus: I usually read the manual first, but sometimes I missed some important issues
01:34 PM _unreal_: unterhaus, not sure what you mean by cw/ccw amp? are you talking about a motor controller?
01:34 PM unterhaus: yes, motor drive amp
01:35 PM _unreal_: most BRUSHED servo motors even bldc's are cw/ccw
01:35 PM _unreal_: unless they have step/dir or quad inputs for motion control
01:35 PM _unreal_: err the drivers that is
01:36 PM unterhaus: I'm pretty sure the amp I'm thinking of wants analog speed and cw/ccw direction
01:36 PM _unreal_: veegee, hello
01:37 PM _unreal_: ve7it, hi
01:37 PM _unreal_: veegee, gets me all the time
01:37 PM _unreal_: ARG..
01:37 PM _unreal_: yet once I do ve7 tab one's it auto defaults to that hehe
01:37 PM _unreal_: ve7it, few questions about the driver
01:37 PM ve7it: yup?
01:38 PM _unreal_: first, is it posible to make a more legible pcb image. I'm having a hard time trying to identify the smd's
01:39 PM _unreal_: the TP numbers are reversed from the bottom pcb info. so I flip the image. I can read one and the other is reversed, and a lot of the info is over lapping making it hard to identify
01:40 PM _unreal_: also the smd caps. are the 0.47 one' 47uF?
01:40 PM _unreal_: the 6mhz crystal, I only have 22 and 33pf caps will ether of those do or do I need the 27pf?
01:40 PM _unreal_: I'm missing a few other cap values anywyas. going to have to order a few
01:42 PM _unreal_: idealy a PCB image with all the resistors/caps with all of the matching values of EACH type all the same color font. would be wonderful
01:43 PM _unreal_: Tom_L, you live still?
01:43 PM Tom_L: yup
01:44 PM _unreal_: so as we were talking about before the belts for my machine, I'm trying to order my idlers right now, both toothed and toothless
01:45 PM _unreal_: 222xl is the pully size I have the 5.08 I believe.
01:45 PM _unreal_: I'm trying to find idlers that are 10mm belt width, and 3mm id bearing toothless and toothed,
01:46 PM _unreal_: https://www.amazon.com/WINSINN-Aluminum-Timing-Toothless-Printer/dp/B07CXNK33Q/ref=sr_1_3?keywords=Timing%2BBelt%2BIdler%2BPulley%2B10mm%2Bwidth&qid=1580059355&sr=8-3&th=1
01:46 PM _unreal_: That will work for me regardless
01:46 PM _unreal_: just trying to find the toothed one now
01:47 PM _unreal_: I dont think these are the right teeth https://www.amazon.com/Idler-Pulley-Timing-Teeth-Printer/dp/B07K8CRT8N/ref=sr_1_2?keywords=Timing%2BBelt%2BIdler%2BPulley%2B10mm%2Bwidth&qid=1580059355&sr=8-2&th=1
01:49 PM Tom_L: i thought you wanted xl
01:49 PM Tom_L: those are GT2 for glue printers
01:50 PM miss0r: 'evening
01:52 PM _unreal_: I do
01:52 PM _unreal_: I'm just trying to find the right ones
01:52 PM _unreal_: the toothless one's dont matter
01:52 PM _unreal_: they are 10mm width and flat and 3mm ID just what I need
01:52 PM Tom_L: they might
01:53 PM Tom_L: you can only wind a belt so tight and if they're too small will compromise the belt life
01:53 PM _unreal_: I'm trying to find the toothed version for the reversed idler pulleys
01:53 PM CaptHindsight: 3mm ID, are the motor shafts that small?
01:53 PM _unreal_: CaptHindsight, IDLERS
01:53 PM _unreal_: they JUST SPIN
01:54 PM Tom_L: use a roller skate wheel
01:55 PM miss0r: CaptHindsight... I've falled in love with a new vehicle.. :) I will probably buy it Friday... :D https://i.pinimg.com/originals/c7/9d/13/c79d13341e9189671053628f0b58da6a.jpg (not the actual one, as I only have photos of it on my phone, but the same (without the radio equipment inside, and it is colored solid green) :D
01:56 PM CaptHindsight: yes, but they provide tension
01:56 PM _unreal_: CaptHindsight, 3mm is more then enough
01:57 PM _unreal_: I could go 5mm but I'd have to come up up with a spacer
01:57 PM CaptHindsight: if you say so
01:57 PM _unreal_: my holes are in the 3mm range
01:57 PM CaptHindsight: miss0r: what is the weight?
01:57 PM _unreal_: CaptHindsight, the the 3mm bolt is captured on two sides
01:58 PM _unreal_: of the bearing/idler
01:58 PM _unreal_: its not free floating on one side
01:58 PM miss0r: CaptHindsight: 3600kg weighed down to 3500kg (total including cargo). I think its around 2400kgs in itself
01:59 PM CaptHindsight: miss0r: what the make and model? I'd like to see the underside
01:59 PM miss0r: its a land rover "101" forward control (radio body)
01:59 PM miss0r: but the 101 forward control is all the same chassis & underside - just different top
02:00 PM CaptHindsight: http://www.parabolicsuspension.com/landrover/lr101.htm
02:01 PM miss0r: yeah
02:01 PM miss0r: The one I am going to purchase is already equipped with modern parapolics
02:01 PM _unreal_: Tom_L, I think this is what I'm looking for :) https://www.ebay.com/itm/XL-12T-40T-Timing-Belt-Tensioner-Pulley-Synchronizing-Wheel-For-10mm-Width-Belt-/152879389862
02:02 PM miss0r: 1450mm wading depth, without snorkle :D
02:03 PM Tom_L: closer
02:04 PM CaptHindsight: miss0r: https://i.pinimg.com/originals/01/b5/b4/01b5b4317fe46dc9fce6853848172720.jpg where this hobby ends up :)
02:04 PM miss0r: doubt it :D I'm not form 'murica
02:05 PM miss0r: The misses and I will convert the 101FC to a small mobile home and do some tours in it
02:05 PM CaptHindsight: https://www.youtube.com/watch?v=XGdva5xnmRk&feature=emb_logo
02:05 PM miss0r: 3.5 litre V8 with a whooping 128BHP
02:06 PM miss0r: holy! I would not dare drive that :D
02:06 PM unterhaus: speaking of finishing projects, I hate to admit I still haven't gotten some of the heatsinks used on the stmbl
02:06 PM _unreal_: Tom_L, omg..... china
02:06 PM miss0r: CaptHindsight: But it realy makes for nice engine access...
02:06 PM _unreal_: seller is on vaca
02:07 PM unterhaus: resistant to ordering from europe
02:09 PM _unreal_: ve7it, ?
02:09 PM Tom_L: why?
02:09 PM Tom_L: would you hesitate ordering from china?
02:10 PM tiwake: virus
02:11 PM unterhaus: I know, it's a bit ridiculous
02:11 PM Tom_L: tiwake, did you see the 10day hospital?
02:11 PM tiwake: Tom_L: I have not been in a hospital in a lot of years
02:12 PM Tom_L: nor i
02:12 PM CaptHindsight: Tom_L: it's OK the virus is already in Chicago
02:12 PM Tom_L: i'd say we're probably better prepared to deal with it
02:12 PM Tom_L: https://www.news.com.au/lifestyle/health/health-problems/china-to-build-hospital-in-10-days-to-treat-patients-with-coronavirus/news-story/d0377171f652528abf5edb50ac4967e4
02:13 PM CaptHindsight: saw the other day
02:13 PM * jthornton gives up trying to get the RPi to play music with the Qt multimedia
02:14 PM CaptHindsight: concrete shell with windows, like the factories there
02:14 PM unterhaus: I'm sort of curious how you get that many people with excavators to do something useful
02:14 PM CaptHindsight: they go up really quick
02:15 PM Tom_L: does kinda look like a cluster fsck
02:16 PM unterhaus: I have also wondered if they have earth movers there
02:16 PM miss0r: looks like a media stunt to me
02:16 PM miss0r: Noone can build anything that fast...
02:16 PM unterhaus: if it was a media stunt, all the excavators would be in echelons
02:16 PM CaptHindsight: i bet it will be a single level
02:17 PM unterhaus: I would use tents
02:17 PM CaptHindsight: concrete slab (obviously) tilt up concrete walls, steel roof
02:18 PM _unreal_: Tom_L, chines newyear
02:18 PM ve7it: _unreal_, do you have eagle version 6 available? (pcb software)
02:18 PM Tom_L: i'm aware
02:18 PM _unreal_: ve7it, I do not have eagle
02:19 PM _unreal_: part of my issue
02:19 PM Tom_L: 4.16 was the last good one
02:19 PM ve7it: it would probably really help... then you can zoom in on various areas of the pcb as you build it
02:20 PM ve7it: let me look, I might still have the zipped up old distro
02:20 PM CaptHindsight: miss0r: I've worked on brick and concrete structures that went up that quick, few hundred people, 300-500 sq meters 1-2 levels
02:21 PM miss0r: sure - it went up that fast. But that is not including; electrical, drywall, paint, flooring and all the rest. Sure you can stack a concrete tower in that time, given enough manpower.. But there are processes that take time
02:22 PM _unreal_: oh looks like there is eagle for linux?
02:22 PM CaptHindsight: miss0r: actually yes, carpet down, paint, electrical and AC
02:23 PM CaptHindsight: well planned in advance, workers 24/7
02:23 PM ve7it: eagle-lin-6.6.0.run is what I was using
02:23 PM miss0r: Ha.. i stand corrected then. I've just never experienced it myself
02:24 PM CaptHindsight: it take lots of cooperation
02:24 PM miss0r: No doubt there
02:24 PM unterhaus: lots of cooperation, no inspections
02:24 PM ve7it: I thought I was using a windows version under wine, but it appears to be for linux
02:24 PM CaptHindsight: and not many interior rooms, just utility and bathrooms
02:25 PM CaptHindsight: will be interesting to see what they build in the next 2 weeks
02:26 PM CaptHindsight: military type barracks
02:26 PM Tom_L: not hospitals as we know them...
02:26 PM Tom_L: barely clinics
02:26 PM CaptHindsight: yeah, likely tents inside
02:27 PM ve7it: Tom_L, I agree, after V6 autocad took it over and converted to rentalware... I now use Kicad for all my pcb projects as its open source with no restrictions and seems very good.
02:27 PM CaptHindsight: but if you really want to contain people and what goes out of the place ...
02:31 PM Tom_L: ve7it, one of the supply houses had it between too
02:31 PM Tom_L: they added their inventory hooks
02:31 PM jymmmm: https://www.tmz.com/2020/01/26/kobe-bryant-killed-dead-helicopter-crash-in-calabasas/
02:31 PM Tom_L: ve7it, if i ever did a board again i'd still use 4.16 :)
02:31 PM CaptHindsight: https://constructionreviewonline.com/wp-content/uploads/2013/03/Precast-Concrete.jpg
02:31 PM CaptHindsight: :) https://cdn.openpr.com/S/4/S422499054_g.jpg
02:31 PM Tom_L: since it was a purchase and can do multi layer larger boards if needed
02:31 PM ve7it: _unreal_, did you find the linux version 6.6? I can post the install image for you if needed
02:33 PM CaptHindsight: "it will be prefabricated buildings, it will not only be built fast but it also won't cost much."
02:33 PM CaptHindsight: I bet it was military just waiting to be used
02:35 PM unterhaus: the only place in the world that seems to have the stmbl heatsink in the exact length is in Germany
02:35 PM unterhaus: $16 for 5 heatsinks, $30 shipping
02:36 PM _unreal_: ve7it, so the caps are those 47uF?
02:36 PM CaptHindsight: machinekit replaced NML with ZeroMQ https://en.wikipedia.org/wiki/ZeroMQ
02:37 PM ve7it: not sure which ones you are asking about....
02:37 PM CaptHindsight: https://machinekoder.com/machinetalk-explained-part-1-introduction/
02:39 PM ve7it: looking at schematic, I only see 0.047 and 0.47 and a few 0.01... and yes 22pf caps should be fine in osc circuit
02:41 PM _unreal_: so aggravating https://www.ebay.com/itm/XL-12T-40T-Timing-Belt-Tensioner-Pulley-Synchronizing-Wheel-For-10mm-Width-Belt/152879389862?var=452635630289 that is exactly what I need
02:42 PM _unreal_: toothed and non toothed
02:42 PM _unreal_: xl 12t
02:42 PM _unreal_: that is the ONLY source google is giving me
02:42 PM _unreal_: no one else seems to have them at all
02:43 PM _unreal_: unless someone else can find those domestic/USA I'm ordering :(
02:43 PM _unreal_: from china and chinas on vaca :S theres a 2month aditional delay
02:44 PM CaptHindsight: https://sdp-si.com/ and McMaster but prices are higher
02:44 PM _unreal_: CaptHindsight, I cant find those that I just listed in sdp or mcmaster
02:46 PM unterhaus: has someone posted the strange parts video from china? I would have so many unfinished projects I would need an intervention
02:47 PM _unreal_: CaptHindsight, I could go with just these but I have a feeling that the reversed side of the pully will give vibrantion and add ware to the teeth
02:47 PM unterhaus: Chinese industrial market https://youtu.be/_ziP_4pouN8
02:47 PM _unreal_: if the teeth are running over a smooth side of the pulley
02:50 PM _unreal_: If I went with JUST these? https://www.amazon.com/gp/product/B07BPHRSN5/ref=ox_sc_act_title_1?smid=A2QQQKMKGVNA5E&psc=1
02:50 PM _unreal_: would it be bad for the teeth? because I'd have to have some of them on the flat belt side and some on the tooth side. would that be bad for the teeth?
02:50 PM _unreal_: ?
02:53 PM _unreal_: wtf? apparently I own a copy of eaglecad 9.5 because I own fusion360
02:53 PM Tom_L: you want teeth on the toothed side and smooth on the smooth side
02:53 PM _unreal_: That what I figured.
02:53 PM Tom_L: _unreal_, they just started bundling it
02:54 PM _unreal_: then I'm going to order the amazon one's that are the "" GT2 smooth because they are the same damn thing
02:54 PM _unreal_: but I still need to find the toothed vesion
02:55 PM _unreal_: just ordered those
03:01 PM _unreal_: and eagle is little help I dont kno whow to use it
03:02 PM _unreal_: Tom_L, so these https://www.amazon.com/gp/product/B07BPHRSN5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1
03:02 PM _unreal_: will be here by tue.
03:02 PM _unreal_: now I just need the other one's :(
03:05 PM Tom_L: did you check the series dimensions between GT2 and XL?
03:08 PM CaptHindsight: unterhaus: you have to get to know the vendors if you want reliable and consistent parts
03:09 PM _unreal_: tom ?
03:09 PM _unreal_: its 10mm width and 5mm bore
03:10 PM _unreal_: gt2/xl its the same thing for the smooth idler
03:10 PM _unreal_: I fail to see any issue
03:11 PM Tom_L: good
03:11 PM CaptHindsight: unterhaus: you never know how they were stored or the source
03:26 PM _unreal_: ve7it, I'm still trying to work out how this thing reverses the motor direction hehe
03:27 PM _unreal_: tp5 is grd? and tp9 is output of the motor controller with both outputs tied to each other
03:27 PM _unreal_: pin 1/2 of the opamp
03:40 PM _unreal_: good lord, If I'm not talking no one is talking
03:41 PM _unreal_: and I have to leave soon to go get the kid :/
03:42 PM _unreal_: ve7it, the devices list in eagle makes it MUCH easier to see
03:42 PM ve7it: _unreal_, output pin re2 is the fwd/rev switch... it just drives the opamp to one limit of the other... the pwm output sets the current output available
03:42 PM ve7it: or the other
03:44 PM _unreal_: oh ve7it just found out what happend to my opamps
03:44 PM _unreal_: they where "" delivered "" on the 17... apparently the morons that shipped the item totally fucked up the address baddly
03:44 PM _unreal_: was delivered to some place in DELTONA, FL 32738
03:46 PM _unreal_: ve7it, I guess what I and no comprehending is how you get a change of direction if one of the motor contacts is on ground :)
03:46 PM _unreal_: what I am not comprehending
03:47 PM ve7it: old school... uses split supply on the op amp, so the op amp output goes to +24 or -24 as needed
03:48 PM ve7it: other side of motor is ground
03:48 PM ve7it: " we dont need no stinkin bridge "
03:49 PM _unreal_: I guess I'm going to make a small jumper breakout board to jump the "TP" points from the main controller to a small board so I can have terminal contacts
03:49 PM _unreal_: less painful then having random contacts
03:50 PM _unreal_: bridge hehe
03:50 PM _unreal_: oh I love my hot air station
03:51 PM _unreal_: makes it so easy
03:51 PM _unreal_: and SIGH... I tossed a bunch of pcbs from things I took appart. wonder if some of the parts I need where on it.
03:51 PM _unreal_: oh well
03:51 PM _unreal_: well time to go drive for 3 QW#$QW$RQWEr hours
03:52 PM _unreal_: ! gaaaa I take that back. I got an hour till I have to leave
03:53 PM ve7it: I used a bunch of the little 0.2" terminal blocks for most of the field connections
03:54 PM _unreal_: ve7it, so I have a 5"x11" heat sink
03:54 PM _unreal_: with 5 1" tall fins
03:54 PM ve7it: should be lots for 3 axis
03:54 PM _unreal_: I'm looking at mounting the thing vertial to the outside
03:54 PM _unreal_: ?
03:54 PM _unreal_: as in plenty of heatsink
03:55 PM _unreal_: I'm looking at cutting the heat sink down to 9"
03:55 PM ve7it: yes... I would use it all as these are linear servo drives, kind of like a stereo system
03:56 PM _unreal_: mounting it to the outside of the case cutting holes and using aluminum spacers to transfer the heat
03:56 PM ve7it: anyway... I am off to the bench to breadboard a circuit.... will be gone for a bit
03:57 PM _unreal_: also looking at putting a cover over it with a fan for forced cooling
04:06 PM Deejay: gn8
04:26 PM _unreal_: Tom_L, ok so i'm done with my testing of the starboard block
04:26 PM _unreal_: ITS a keeper
04:27 PM _unreal_: the starboard block has ZERO backlash. Any of the things I was doing before to try and ensure I didnt have issues with backlast were a waste of time
04:28 PM _unreal_: infact I've been running the TAP back and forth trying to ware away the thread a bit because the block AS IS is too tight. I just got it to where i'm ok with it
04:28 PM _unreal_: and I've found no ware
04:29 PM _unreal_: soon as I put a little silicon grease on the thread the little bit of heating I was getting on the threaded rod stopped instantly
04:31 PM unterhaus: what is starboard? wrong name for namespace collisions
04:35 PM _unreal_: namespace?
04:35 PM _unreal_: unterhaus, try google
04:36 PM unterhaus: that's what I'm talking about google talks about all the other things called starboard
04:37 PM unterhaus: as you might imagine, most of them are related to the left side of boats
04:37 PM unterhaus: I can just imagine the MBA's, let's pick a name so that nobody will be able to find our product on google
04:47 PM unterhaus: I finally realized why the stmbl heatsink is a little weird, it's for 2 rows of to220 devices
04:47 PM _unreal_: unterhaus, try king starboard
04:48 PM unterhaus: okay
04:48 PM _unreal_: unterhaus, ?
04:49 PM unterhaus: the smbl uses a 46mm by 33mm heat sink with a slot at the normal height of a to220 transistor
04:50 PM unterhaus: I think it's made so the transistors are 50mm on center, thus 46mm heat sink
04:51 PM _unreal_: unterhaus, the ? was for the starboard
04:51 PM _unreal_: do you know waht it is now?
04:52 PM unterhaus: polyethelene
04:52 PM SpeedEvil: https://www.kingplastic.com/products/king-starboard/
04:53 PM _unreal_: if you have never played with it, it is one of the best building materials you'll find
04:53 PM _unreal_: easy to mill
04:54 PM _unreal_: very strong, chemcial resistant
04:54 PM _unreal_: uv stable
04:54 PM _unreal_: and more
04:54 PM _unreal_: and with that I have to go get my daughter
05:08 PM unterhaus: ordered from Newark, shipping from the U.K., hopefully that works out
05:16 PM skunkworks: https://youtu.be/2SEB7TuCUR0
05:29 PM unterhaus: did you add the gear for the spindle encoder?
05:33 PM unterhaus: how fast can you go in high range
05:34 PM skunkworks: 10k
05:34 PM skunkworks: yes - I added the gear...
05:36 PM unterhaus: looks great, do you have pictures inside the cabinet?
05:36 PM skunkworks: https://www.youtube.com/watch?v=QY_vmW1djao
05:37 PM skunkworks: unterhaus: http://electronicsam.com/images/greenmachine/IMG_20191215_131330.jpg
05:37 PM skunkworks: still messy
05:42 PM Tom_L: where'd you find that box?
05:43 PM jthornton: got a bill for my part of an echo cardiogram I got last February total cost $2,847 my cost $185... I'm liking medicare
05:43 PM Tom_L: no kidding
05:43 PM Tom_L: i've paid for a couple pet scans...
05:45 PM jthornton: when I was on my wife's insurance it cost me $2k
05:46 PM jthornton: they didn't pay shit lol
05:46 PM XXCoder: IINO. insurance in name only
05:46 PM jthornton: https://matrix.org/_matrix/media/r0/download/matrix.org/eImQQmWyqBpWTpiUlIRnRutB
05:47 PM XXCoder: that was what aca was fixing
05:47 PM Tom_L: pet scans are ~3k a pop and want paid up front
05:47 PM jthornton: yea, the local hospital want's to be paid upfront too
05:48 PM Tom_L: jt you've got entirely too much space there
05:48 PM Tom_L: you can actually move around without bumping into something!
05:48 PM XXCoder: lol
05:48 PM XXCoder: love the ikea lamp mod there
05:48 PM jthornton: https://matrix.org/_matrix/media/r0/download/matrix.org/TvtobjgaBOnIruCWGpeAjONy
05:49 PM jthornton: https://matrix.org/_matrix/media/r0/download/matrix.org/SSrKrQjAgYVTOLIXyZvtXzGq
05:49 PM jthornton: yea, needed the ikea mounted as it was always in the way
05:49 PM Tom_L: was yours the clip style?
05:49 PM Tom_L: i've got a couple
05:49 PM jthornton: no, it had a huge heavy base
05:49 PM Tom_L: one by the lathe and drillpress
05:51 PM unterhaus: skunkworks, did you have that stmbl case made? I had some stuff done by oshcut recently, came out nice
05:52 PM jthornton: https://www.amazon.com/Ikea-201-696-58-Jansjo-Light-Black/dp/B0055IVM1I
05:52 PM XXCoder: 25? what a ripoff
05:52 PM XXCoder: bought both mine for $10
05:52 PM jthornton: yea, could not find the ikea one
05:53 PM jthornton: https://matrix.org/_matrix/media/r0/download/matrix.org/RRoMxGeRAmLJjvGBrLwbFRWq
05:54 PM XXCoder: new version https://www.ikea.com/us/en/p/naevlinge-led-work-lamp-black-40404914/
05:54 PM XXCoder: less flexable it seems
05:55 PM XXCoder: makes it useless for shop stuff. too bad
05:55 PM jthornton: yea
05:55 PM XXCoder: seems neck is flexable but short length
05:56 PM Tom_L: https://www.ikea.com/us/en/p/naevlinge-led-clamp-spotlight-black-30449885/
05:57 PM XXCoder: seem that is full length flexable. nice
06:03 PM jthornton: time to cook some chow
06:03 PM jthornton: oh and this mornings test was a failure...
06:05 PM XXCoder: drat
06:10 PM skunkworks: unterhaus: bought them from andy with the drives..
06:11 PM XXCoder: kobe bryant died in helicoper crash with his 13 year old daugher
06:17 PM unterhaus: skunkworks: since I still haven't gotten mine running, I should have just waited to get everything instead of just the boards
06:19 PM skunkworks: I havn't blown one up.. That is saying a lot :)
06:30 PM unterhaus: how many are you using?
06:31 PM unterhaus: people blowing them up slowed me down a little
06:37 PM skunkworks: I have played around with a few of them. But currently one driving the spindle
06:37 PM unterhaus: looks like at qty 5, cases are going to cost me $15 each, steel, aluminum, or stainless
07:19 PM sliptonic: Somebody help me think here. I'm stumped. I need to run both machinekit and Linuxcnc so I can test software being written for FreeCAD. I've set up my machine to build both MK and Linuxcnc from source. That's working now and I can rip-environment and launch either. So far, so good.
07:20 PM sliptonic: In the Machinekit config, it launches, I can home, jog, touchoff, etc. Macros work for retracting spindle. Spindle starts. All good. But if I run a program, it just sits there. Does nothing.
07:22 PM sliptonic: My first guess was the hal-manualtoolchange component, but it seems to be wired correctly. I'll ask about this on the MK forum but I was looking for suggestions where to hunt for clues.
07:22 PM sliptonic: On the linuxcnc config, even though the configuration is identical in terms of joint/axis setup, I immediately get following errors when enabling the machine.
07:25 PM sliptonic: My guess on that is related to the joint/axis changes but as far as I can tell, the .ini has been updated for the JA changes.

08:25 PM veegee: Instructions on my mill for replacing motor don't mention the bottom bearing
08:25 PM Tom_L: it never goes bad :)
08:25 PM veegee: Bridgeport mills don't have that bottom bearing apparently
08:26 PM veegee: But mine does, which is great, but they forgot to mention I need to pull the bearing off the old motor shaft and install it on the new one :(
08:26 PM veegee: Now I need to wait until tomorrow until my bearing puller arrives

09:03 PM _unreal_: been a while
09:04 PM pink_vampire: yeah
09:04 PM XXCoder: hey been a bit
09:04 PM XXCoder: pink been playing with laser engraver
09:04 PM XXCoder: fun
09:05 PM pink_vampire: no, even worse than that!
09:05 PM pink_vampire: I 3d print some stuff alllll dayyy longg
09:05 PM XXCoder: :) making stuff or statues?
09:07 PM pink_vampire: bunch of cool stuff
09:07 PM pink_vampire: I even cut down my cnc enclosure
09:08 PM XXCoder: huh?
09:08 PM XXCoder: making it or removing?
09:08 PM pink_vampire: shrink it down
09:09 PM XXCoder: ahh ok
09:09 PM pink_vampire: who need a cnc when you have pla parts!
09:10 PM * _unreal_ raises hand
09:11 PM pink_vampire: I'm joking.
09:12 PM pink_vampire: I just need to make some room for some tools.
09:12 PM XXCoder: cool
09:12 PM pink_vampire: and I want to have a place to put peg board
09:15 PM _unreal_: right now I'm designing my acrylic front cover for my new cnc machine, this will be the stand off cover/outer bearing/pulleys support for the new machine
09:15 PM pink_vampire: is that the mini fiberglass machine?
09:19 PM _unreal_: omg. estimated delivery march 15th
09:22 PM _unreal_: there thats done
09:22 PM _unreal_: though I cant Q@#$%!@#$ mill the damn part because my daughters bedroom is next to mine :(

10:39 PM XXCoder: nice box type router cnc
10:39 PM nvz: yeah now that its all together I see we're not actually getting a 4x4ft workarea
10:39 PM nvz: its like maybe 2-2.5in shy on the Y and about that much more on the X
10:40 PM nvz: if I leave the gantry as-is I have an 8.5in travel distance on it
10:40 PM nvz: on the Z that is
10:41 PM nvz: but with the spindle mounted as low as I can mount it, it'd still be 2.5in above the surface.. and a bit would probably only be like 1.5in at most
10:41 PM nvz: and I'd already planned on making a maybe 3/4in work surface on top
10:41 PM nvz: so we may lower the beam and lose 3in on the Z axis or just use a stage for the work area
10:42 PM nvz: it'd make it far less likely we ever damage the surface of the machine which is expensive wood
10:43 PM nvz: I got the Y axis drag chain mounted with wires strung for the two Y axis motors.. and got the Y-axis belts cut to length before I stopped tonight
10:48 PM nvz: we probably got like US$1100 into it right now
10:51 PM nvz: I'm still not real sure on the wiring, but seems like those drivers are fairly flexible.. they seem to have various wiring configurations..
10:51 PM nvz: the power side of them that goes to the motors is pretty straightforward, its the signal side of them I'm not real certain on
10:51 PM pink_vampire: XXCoder: what laser machine???
10:51 PM XXCoder: one I got while after you left lol
10:52 PM nvz: I went with a negative connection.. wired all the positive together and put the singal on the negative
10:52 PM XXCoder: its $100 one cheapass one. then I had to get better laser engraver controller board for it
10:52 PM pink_vampire: I didn't left
10:52 PM XXCoder: its cheapass but NOT dvd drive movements type
10:52 PM nvz: :P
10:53 PM nvz: I've seen machines made out of cd/dvd drive motors before
10:53 PM XXCoder: yeah I avoided those
10:53 PM nvz: https://www.youtube.com/watch?v=01NJgm7Sk8M
10:54 PM nvz: personally those things crack me up the most
10:56 PM nvz: https://www.youtube.com/watch?v=c52JQHVVqFM heh.. @.@ this is what happens when microcontrollers get this cheap
10:58 PM nvz: of course it gets funnier when they add in other hardware https://www.youtube.com/watch?v=oqwZzuOXYPU

11:50 PM _unreal_: nvz, you have forced air flow for those psu's ya?
11:50 PM rue_mohr: _unreal_, so, your workin on a dc motor driver?
11:51 PM _unreal_: rue_mohr, ?
11:51 PM _unreal_: ahh? yes
11:51 PM rue_mohr: driectional?
11:51 PM _unreal_: ?
11:51 PM _unreal_: care to be a little more specific?
11:52 PM rue_mohr: I'm building a cnc with dc motors, just working on drivers, my specs are 20A 30V curious about yours
11:52 PM _unreal_: building the drivers?
11:52 PM _unreal_: I'm building these drivers http://ve7it.cowlug.org/dspic-servo.html
11:53 PM _unreal_: and I litteraly have the same servo motor in the photo

11:55 PM _unreal_: 24v, I dont really know the power they dont say.
11:55 PM _unreal_: litteraly the motors dont say
11:55 PM rue_mohr: opa549....
11:56 PM _unreal_: the one on the ve7it website that I have the same one is 24oz/in
11:56 PM _unreal_: my new machine I'm bilding I'm gearing down and making lead screw driven
11:56 PM _unreal_: not super fast but VERY powerful
11:56 PM rue_mohr: 8A continious, not bad for a little package
11:56 PM _unreal_: its a HEAT maker
11:57 PM rue_mohr: yea, I been waiting for my leadscrew cnc for years
11:57 PM rue_mohr: since 1998
11:57 PM _unreal_: ?
11:57 PM rue_mohr: k, +-25V...
11:58 PM XXCoder: pink_vampire: just had first successful cutout
11:58 PM _unreal_: you hav e been waiting for 22 years for lead screws?
11:58 PM pink_vampire: XXCoder: pics!!!
11:58 PM XXCoder: in a bit
11:58 PM rue_mohr: wow 4V drop, so, at 8A your into 64w
11:59 PM rue_mohr: _unreal_, yes, its part of the reason I dont use the machine much
11:59 PM _unreal_: rue_mohr, I have no idea what your talking about..
11:59 PM rue_mohr: that and parallel port-controlled-unipolar stepper drivers :)
11:59 PM rue_mohr: the machine is slow
11:59 PM rue_mohr: quite slow
