[00:00:24] <BeachBumPete> I ran off the sidewalk to miss her and my homebuilt bike has the very skinny high pressure tires
[00:00:44] <XXCoder> ow so it warped like hell
[00:00:51] <XXCoder> sending you down to taste road
[00:01:05] <BeachBumPete> It did fine right up until I tried to get back on The sidewalk
[00:01:17] <XXCoder> lol guessed wrong
[00:01:36] <BeachBumPete> I kinda got caught in the grooved between the grass and sidewalk
[00:01:50] <BeachBumPete> Next thing I know am going over
[00:02:08] <BeachBumPete> Luckily I don't have far to fall
[00:02:51] <XXCoder> had few close calls but never seriously hgurt on bicycle myse;f
[00:02:58] <BeachBumPete> The funny thing is I kinda hopped off the bike and turn around only to see my daughter yellling and about to run me over hehehe
[00:03:01] <XXCoder> my bro we guess someone hit him from behind with bicucle
[00:03:06] <XXCoder> tire is badly warped
[00:03:26] <XXCoder> my bro dont remember anything he was riding and he gets off road and wonder what happened
[00:03:34] <BeachBumPete> I actually grabbed her handlebars and caught her bike
[00:03:57] <BeachBumPete> But I kinda hurt my ankle in doing so
[00:04:12] <BeachBumPete> Oh man that sucks
[00:04:22] <XXCoder> been years ago but yeah
[00:04:38] <XXCoder> broke arm but luckly had helmet so it wasnt worse than what happened
[00:04:44] <BeachBumPete> My handlebars are bent a bit but repairable and I rode the bike home
[00:06:23] <BeachBumPete> I gotta remove the bars and get them bent back but it has under seat steering and the shutters and brake cables run inside the bars so it's kinda time consuming
[00:06:42] <BeachBumPete> Shifters
[00:07:26] <XXCoder> in least its nicely repairable :)
[00:07:52] <BeachBumPete> Yeah I can rebuild it if necessary
[00:08:12] <BeachBumPete> I made the whole frame and whatnot
[00:09:02] <BeachBumPete> I kinda want to redo the link steering anyway it is fine but it could be better
[00:10:53] <BeachBumPete> If you let the front wheel turn too far to one side it kinda locks from overcenter
[00:11:15] <FloppyDisk525> glad you're okay. taking a spill on a bike can be nasty.
[00:11:30] <BeachBumPete> But it is way beyond anything that you would experience when actually riding the bike
[00:11:46] <BeachBumPete> Thanks Floppy
[00:12:10] <BeachBumPete> We all wear helmets and whatnot but yeah I'm fine mostly
[00:12:13] <XXCoder> indeed
[00:12:47] <BeachBumPete> I'm just glad I didn't make her wreck or slam into her
[00:12:54] <Crom> Rooster Teeth and youtube red made a movie Laser Team.. Great movie, funny as all get out, stupid in places, smart in others and all the way through great production values
[00:13:35] <Crom> spill on a bike... been there done that..
[00:14:13] <Crom> ended up with a drill chuck key stuck in my leg about 1/2"
[00:14:37] <BeachBumPete> I must say that I have had like three spills on my homebuilt recumbent bike and never got more than a skuff
[00:15:15] <Crom> I needed wheels, and the only thing I could afford was a bike
[00:15:28] <BeachBumPete> I think that the fact you are sitting with feet forward kinda helps
[00:15:43] <BeachBumPete> Ouch
[00:17:03] <BeachBumPete> I actually have a nice brand new front form with the steering linkage arm installed on it already I need to tear down the bike and get it installed
[00:17:10] <BeachBumPete> Fork
[00:17:59] <BeachBumPete> The fork has a bit of forward offset that might actually help the steering overcenter locking issue
[00:18:41] <XXCoder> dammit!
[00:18:45] <XXCoder> freecad crashed
[00:18:50] <XXCoder> eating some of progress with it
[00:18:53] <BeachBumPete> I also want to install one of those chain tube guards
[00:19:24] <BeachBumPete> I have not used freecad for awhile now
[00:19:37] <BeachBumPete> Been busy with other things
[00:19:56] <BeachBumPete> Wonder if they have made any progress with updates
[00:20:05] <XXCoder> im using latest stable 0.16
[00:20:09] <XXCoder> its largely great
[00:20:12] <XXCoder> .17 dunno
[00:20:40] <XXCoder> in least i didnt have to do the complex clamp design again, just holes
[00:21:29] <BeachBumPete> Yeah save often
[00:21:38] <XXCoder> indeed forgot that rule lol
[00:22:12] <BeachBumPete> I don't remember but I thought there was an auto save feature no?
[00:22:20] <Crom> I had freecad install apt-get uninstalled it
[00:22:42] <XXCoder> BeachBumPete: yeah thats why I didnt have to do all over again
[00:22:45] <XXCoder> I didnt save once
[00:22:58] <BeachBumPete> Ah
[00:23:50] <BeachBumPete> I bought the alien boxed set today at waly world for $3.74
[00:24:12] <BeachBumPete> Four movies in one box pretty cool
[00:24:27] <Crom> Use 'apt-get autoremove' to remove them. The following packages will be REMOVED: freecad
[00:24:32] <BeachBumPete> My daughter's had never seen them
[00:24:32] <Crom> grrrr
[00:24:54] <XXCoder> add freecad repo
[00:25:12] <BeachBumPete> I forgot just how scary the alien monster really is LOL
[00:25:15] <XXCoder> you shouldnt be using distro copy anyway as its usually old and sucks
[00:26:06] <Crom> sudo dpkg -i freecad_0.16.6703-1ppa1-ubuntu16.04.1_i386.deb
[00:26:14] <Crom> only thing I could find
[00:26:56] <BeachBumPete> Well I'm falling asleep gn8 folks
[00:26:57] <Crom> ahhh wheezy support 0.14
[00:27:37] <XXCoder> night seaman
[00:55:23] <XXCoder> http://picpaste.com/pics/Screenshot_2016-09-03_22-26-38-AciZaQAW.1472966866.png
[00:55:39] <XXCoder> it is 50 mm tall, 80 mm wide
[00:55:46] <XXCoder> its to hold 52 mm spindle
[00:56:17] <XXCoder> im not too sure about that clamp halves bolt parts, it is 2.5 mm thick and probably too weak
[01:15:16] <Kevin`> XXCoder: some reason you don't just run some or all of those bolts through all three pieces?
[01:15:25] <XXCoder> cant be done
[01:15:31] <XXCoder> it will impact on spindle
[01:15:34] <XXCoder> I think
[01:15:36] <XXCoder> hmm
[01:16:16] <XXCoder> well the spindle is 52mm
[01:16:22] <XXCoder> bolt pattern is 63 mm
[01:16:31] <XXCoder> that leaves 11 mm or 5.5 mm per side
[01:16:37] <XXCoder> very tight
[01:20:52] <XXCoder> well
[01:21:02] <XXCoder> Kevin`: I might have different clamp design idea
[01:21:17] <XXCoder> problem is I need to match design with bolts that actually exist
[01:22:40] <Kevin`> would it make things any easier to use a split circle instead of two parts?
[01:23:06] <XXCoder> split circle it might be less tight I guess?
[01:23:28] <XXCoder> though in this case if I design a bolt though, split circle makes desogn actually harder
[02:12:47] <Crom_> https://video-lax3-1.xx.fbcdn.net/v/t42.1790-2/14145302_1245828192128743_1623002383_n.mp4?efg=eyJ2ZW5jb2RlX3RhZyI6InN2ZV9zZCJ9&oh=0dfa8a199eb738f74922ea810fc62b8d&oe=57CBFB37
[02:13:17] <Crom_> stupid lady... don't be holding a drink or drinking when you hear this
[02:14:18] <XXCoder> so its pure sound
[02:14:20] <XXCoder> what happens?
[02:15:19] <Crom_> Donna wants the state to move the deer crossings to better areas, so she doesn't hit them, as she has had 3 times previously
[02:15:42] <XXCoder> lol
[02:15:59] <Crom_> she wonders why the state puts these deer crossings in such high traffic areas
[02:16:18] <XXCoder> guess she confused cause and effect
[02:23:34] <XXCoder> Kevin`: https://www.thingiverse.com/thing:1039033
[02:23:37] <XXCoder> great idea
[02:23:41] <XXCoder> simpler and stronger
[02:42:54] <Deejay> moin
[02:46:40] <XXCoder> hey
[02:51:33] <Deejay> you are all day up, aren't you? ;)
[02:52:03] <XXCoder> 12 am now
[02:52:10] <XXCoder> I usually sleep at maybe 3 am or later
[02:55:07] <Deejay> 9 am here
[02:55:31] <Deejay> so u are not located in the US
[02:56:19] <XXCoder> I am
[02:56:45] <XXCoder> https://cdn.thingiverse.com/renders/08/a4/05/16/e2/8b32ab3c667145cd34a4e05d9bfb32f4_preview_featured.JPG
[02:56:50] <XXCoder> is this really strong enough?
[02:57:02] <XXCoder> if it is, I can make it smaller and use less plastic
[02:57:18] <Deejay> hmm
[03:02:10] * Deejay would tend to make it stronger ;)
[03:02:49] <XXCoder> heh
[03:03:04] <XXCoder> im definitely adding some holes though
[03:15:09] <XXCoder> changed design a little http://picpaste.com/pics/Screenshot_2016-09-04_00-46-58-M19oDMF9.1472975240.png
[03:48:35] <XXCoder> hm
[03:48:54] <XXCoder> I cant find any 52 mm spindlethat can be controlled by controller
[05:01:03] <XXCoder> hey guys
[05:01:05] <XXCoder> https://www.thingiverse.com/thing:1653797
[05:01:11] <XXCoder> wrong link a sec
[05:01:17] <XXCoder> https://www.kickstarter.com/projects/tropicallabs/mechaduino-powerful-open-source-industrial-servo-m/description
[05:01:28] <XXCoder> this call what seems to be stepper with encoder servos
[05:01:33] <XXCoder> I dont think its correct but...
[05:15:53] <archivist> you can fiddle/drive a stepper like a servo but, be careful of the claims
[05:16:14] <XXCoder> yeah it looks like stright closed loop stepper
[05:16:39] <XXCoder> its pretty cheap and awesome but still not servos. you cannot connect servo to stepper controller for exampke from what I understand
[05:17:23] <archivist> you can use a step dir "servo"
[05:17:40] <XXCoder> interesting
[05:17:48] <XXCoder> I o want to grab 3 of those lol
[05:17:55] <XXCoder> but tb6560 dont support any feedback
[05:18:45] <archivist> just add the magnet and get one of the encoder chips, feedback to linuxcnc
[05:19:18] <XXCoder> how is magnet used?
[05:19:32] <XXCoder> also encoder chips I guess need to use its own pin
[05:19:34] <archivist> on the end of the shaft
[05:20:26] <archivist> chip is guessing position from magnetism, resolution is 14 bit accuracy is somewhat less
[05:21:08] <XXCoder> ah
[05:21:13] <XXCoder> so its not perfect
[05:21:35] <XXCoder> I wonder what its resolution in terms of linear travel
[05:21:48] <XXCoder> assuming 4 mm per rotation
[05:25:28] <XXCoder> http://www.cnczone.com/forums/general-cnc-machine-related-electronics/238640-cnc.html HMM
[05:31:54] <jthornton> morning
[05:32:21] <XXCoder> yo
[05:32:43] <XXCoder> https://www.amazon.com/Brush-Spindle-Motor-Controller-Cutting/dp/B01J1X6VB8
[05:32:47] <XXCoder> this has PWN
[05:33:05] <XXCoder> does it mean my tb6560 can control it, as in set speed, off and on
[05:33:30] <archivist> linuxcnc does pwm
[05:33:48] <XXCoder> yeah but does tb6560? answers around is bit muddled
[05:34:03] <archivist> tb is a stepper controller
[05:34:17] <XXCoder> it does have connectors for spindle
[05:34:31] <XXCoder> just not sure exactly what
[05:34:38] <archivist> some BOBs have pwm filters for the spindle drive
[05:34:59] <XXCoder> BOB hm thats new to me
[05:35:14] <archivist> break out board
[05:35:22] <XXCoder> ahh
[05:36:24] <archivist> http://www.ebay.co.uk/itm/5-Axis-CNC-Breakout-Board-with-Optical-Coupler-For-Stepper-Motor-Driver-MACH3-CF-/272041782661
[05:37:50] <XXCoder> just not sure what to do with my machine lol
[05:38:12] <XXCoder> I have designed a clamp for 52 mm spindle that can be mounted on my machine frame
[05:38:22] <XXCoder> http://picpaste.com/pics/Screenshot_2016-09-04_00-46-58-M19oDMF9.1472975240.png
[05:47:00] <XXCoder> what ya think archivist heh
[05:47:56] <archivist> I think screws cannot get past fat bits
[05:48:24] <XXCoder> bolts are 1 cm long it should be able to get in
[05:48:54] <archivist> draw a bolt with head and try to assemble in cad
[05:49:09] <XXCoder> ok
[05:51:55] <XXCoder> hmm youre right
[05:52:15] <XXCoder> even countersunk will have issues
[05:54:43] <XXCoder> allright I think I have idea
[05:55:53] <archivist> I have seen a lot of "impossible to assemble" or "modified to assemble" or Friday I saw "added spacers because forgot"
[05:56:24] <XXCoder> I thought there was enough space to insert bolts in
[05:56:54] <archivist> you forgot the bolt heads :)
[05:57:02] <XXCoder> indeed
[05:57:19] <archivist> or the flats for the heads
[05:57:36] <XXCoder> it has sunk area for head
[05:57:43] <XXCoder> but bolts simply cant be inserted
[05:59:19] <archivist> I was repairing a network analyser Friday, that had added washers due to a design error between meter movement and brackets
[06:00:07] <enleth> XXCoder: you could elongate the holes a little to be able to insert the bolts at an angle before assembly
[06:00:40] <XXCoder> probably but thats harder to do in cad for me heh
[06:01:41] <enleth> elongate them after machining
[06:01:54] <XXCoder> it will not be machined
[06:08:24] <XXCoder> it looks pretty cool lol
[06:08:32] <XXCoder> quite by accient
[06:10:53] <XXCoder> archivist: http://picpaste.com/Screenshot_2016-09-04_00-46-58-YwzN3Pu5.png
[06:18:34] <archivist> wrong type of fix for a cnc spindle
[06:19:01] <archivist> it has lost rigidity
[06:19:20] <XXCoder> should be still fine for wood and light alum
[06:19:34] <archivist> and probably still got problems getting bolts in
[06:19:46] <XXCoder> nah its clear now
[06:20:56] <archivist> prove it with a bolt on the drawing
[06:21:42] <XXCoder> I can see it completely clear when looking facing it now
[06:21:47] <XXCoder> meaning clear path in
[06:22:30] <archivist> show standard 3 views not isometric
[06:23:06] <XXCoder> second, busy checking slicing it
[06:23:22] <archivist> I see two interferences per bolt hole
[06:23:43] <XXCoder> yeah curves throw preciption off
[06:24:23] <archivist> I am looking at the flat surfaces to see the errors
[06:24:54] <XXCoder> interesting print pattern
[06:24:57] <XXCoder> "touching bed" heh
[06:25:09] <XXCoder> support for font part that dont touch surface
[06:25:24] <XXCoder> 2 hours 22 min, uses 18 meter of filiment
[06:27:48] <XXCoder> http://picpaste.com/Screenshot_2016-09-04_00-46-58-MN4unCCM.png
[06:30:48] <XXCoder> so what ya think heh
[06:33:08] <archivist> I see cheating, smaller bolt now you have a flat, where there was hole
[06:33:24] <XXCoder> huh
[06:33:47] <archivist> look http://picpaste.com/Screenshot_2016-09-04_00-46-58-YwzN3Pu5.png
[06:33:48] <XXCoder> only alterations I did was clamp holes closer together and trim of
[06:34:14] <archivist> the hole goes is full diameter through
[06:34:18] <XXCoder> it isnt
[06:34:32] <XXCoder> youre looking at sunk bores for bolt head to go in
[06:34:59] <archivist> well not enough metal at bottom of hole
[06:35:03] <XXCoder> sunk area is 5 mm deep, while base is 10 mm
[06:36:57] <XXCoder> it will be PLA plastic actually
[06:37:10] <XXCoder> strong enough for wood im sure. alum probably not.
[06:37:27] <XXCoder> maybe take alum slowly (and complete adoptor plates that way
[06:37:39] <archivist> methinks plastic is a bit silly for machining metal
[06:38:35] <XXCoder> yeah its not really strong enough for anything stronger than light alum cutting
[06:39:45] <archivist> light plastic machining and aluminium crashing
[06:43:45] <miss0r> I must admit, I am plesently surprised of this x-carve... I am building an 18" woofer for my home cinema, it seems to do pretty good
[06:43:58] <XXCoder> yeah? wood eh
[06:44:09] <miss0r> indeed. I would never have it do anything harder than that
[06:45:15] <miss0r> my first runin with grbl, and that sucks - no questions there
[06:48:49] <miss0r> and theres nothing like the high pitch sound of a 25k rpm spindle, the day after attending a friends wedding..
