[02:46:04] <miss0r2> XXCoder: Yesterday I made the deal of the year
[02:46:11] <XXCoder> yeah?
[02:46:21] <miss0r2> yeah... 2 secs, let me take a photo
[02:48:40] <miss0r2> https://imgur.com
[02:49:06] <miss0r2> ~130eur :D
[02:49:12] -!- c-log has quit [Ping timeout: 245 seconds]
[02:49:37] <XXCoder> whats it?
[02:49:44] <miss0r2> xxcoder: and I've tested it out. it measured right on the spot
[02:49:54] <miss0r2> its a 3-point bore measure
[02:50:06] <XXCoder> bore gage?
[02:50:09] <XXCoder> ahh
[02:50:10] <miss0r2> ranging from 20-100mm
[02:50:17] <XXCoder> interesting. 3 point
[02:50:28] <miss0r2> 1/1000 precision
[02:50:33] <miss0r2> mm
[02:51:10] <miss0r2> the pistol grip alone is ~600usd used
[02:51:43] <XXCoder> man thats crazy
[02:51:53] <XXCoder> it looks like QA set too

[02:52:56] <miss0r2> Yeah. I bought it from a guy who refurbishes highspeed spindles. He bought a new set because this started to look worn
[02:52:57] <miss0r2> :)
[02:53:12] <miss0r2> and the prices he charges, he can't have anything not looking new in the shop
[02:53:25] <XXCoder> jeez.
[02:53:37] <miss0r2> yeah
[02:53:38] <XXCoder> its olviously priced to go out now
[02:54:01] <miss0r2> only because I know him, and we work together alot
[02:54:29] <miss0r2> I think he could've gotten 3-4k eur for this set without blinking
[02:55:44] <miss0r2> now I am off to go look at a, from what i'm told, sizeable reamer collection that is for sale cheap
[02:55:59] <XXCoder> nice
[02:56:15] <miss0r2> one hour drive each way - so I hope it is sizeable ;)
[02:57:40] <XXCoder> whole 2 or 3? ;)
[02:58:00] <XXCoder> or only one 1" reamer shattered into 100 reamer parts? ;)
[02:59:27] <miss0r2> We will see :D
[03:00:23] <XXCoder> i found older cnc project of mine, its wood engraved with "ILY" hand shape plus ILY word
[03:00:35] <XXCoder> I painted engrave with black 2.0. damn it looks good
[03:00:53] <miss0r2> sounds nice
[03:01:12] <XXCoder> yeah
[03:01:13] <miss0r2> picture or it didn't happen
[03:01:16] <miss0r2> :D
[03:01:23] <XXCoder> lol few sec

[03:04:28] <miss0r2> that looks pretty nice yeah!
[03:04:50] <XXCoder> yeah
[03:05:51] -!- koom has joined #linuxcnc
[03:06:06] <miss0r2> how long did that take to engrave?
[03:06:13] <XXCoder> couple minutes?
[03:06:22] <miss0r2> at what depth?
[03:06:27] <XXCoder> varied
[03:06:33] <miss0r2> ha
[03:06:35] <XXCoder> it uses v tool lemme get link
[03:06:52] <miss0r2> so... you ran it with 20k rpm or something crazy like us mortals cannot get? :D
[03:06:57] <XXCoder> https://www.youtube.com
[03:07:25] <XXCoder> it could run much faster im still new on programming side lol
[03:08:00] <miss0r2> made a nasty noise in the ILY part... :D
[03:08:18] <miss0r2> machine is not rigid enough for that DOC/size endmill
[03:08:19] <pink_vampire> XXCoder: did you power on your cnc?
[03:08:28] <XXCoder> i was definitely nervious, it was programming error, way too deep
[03:08:40] <XXCoder> pink not for while :(
[03:08:45] <pink_vampire> it is from 2017
[03:09:02] <pink_vampire> I need bigger one
[03:09:24] <miss0r2> bah.. I need to get going. See you around
[03:09:35] <XXCoder> later :)
[03:09:40] <XXCoder> glad you liked pic

[08:26:50] <Elmo40> ugh... damn steppers are skipping on the daughters 3D printer. i thought TMC2208s would help.
[08:33:51] <Elmo40> i'd like to build her machine like my mill... i just might if this issue doesn't get resolved! at the very least get a real driver for the shifting axis.
[08:40:51] <jthornton> damn tobacco hornworms are back

[09:19:08] <jthornton> haven't seen any for a couple of months and now I've pulled 20 or so off the plants
[09:19:30] <jthornton> I know they bury up in the soil after they are done eating
[09:20:10] <jthornton> and oddly enough the tomatoes on the deck have never had them
[09:26:37] <Loetmichel> hmpf... just looked for new tyres for my BMW... 225/60R15-96W in "all year" are not to find anywhere... so i have to drive the winter tyres until they fail. will not buy new summer AND winter tyres for a car that will probably only live to spring 2020 (when its roadworthy check expires)

[10:07:51] <Loetmichel> gregcnc: doesent help if that size isnt produced :-)
[10:08:44] <gregcnc> get a spare wheel/tire set that fits the car, pften quite cheap here
[10:09:00] <gregcnc> I just put X5 wheel on my honda minivan
[10:22:14] <gregcnc> When making D bits from annealed rod, do they bend much during hardening?

[10:40:35] <Elmo40> Loetmichel, ^^
[10:45:59] <Elmo40> i'm printing with a 1.2mm nozzle :-) The extruder is spinning SO FAST!
[10:46:31] <Elmo40> print is cut from 18Hr to 7Hr. I hope I don't burn out the extruder motor.
[10:50:49] <Elmo40> looks like her 8mm LMUU bearings were binding on the rod. i loosened the screws and adjusted them a little. seems to be working fine now. i should upgrade her to linear rails

[13:29:48] <elmo40> why is my freenode connection dropping?? my other servers are not so it can't be my internet (i'm on fibre anyways. it rarely drops)
[13:31:09] <elmo40> i tell ya, printing with a 1.2mm nozzle is something else! almost like warming the filament and simply laying it down. LoL
[13:32:28] <elmo40> ohh, interesting. just noticed Ultimaker is no longer listing their previous versions. They forward you to github.

[13:36:47] <elmo40> looks like 4.3 Beta is out. they still haven't done what many have asked... give us a text box to allow us enter the exact rotation angle we want. They have a new feature, though. Select Face to lay on the build plate. Good idea but the items I want to print need a flat top, not bottom. Just give me the input box like Repetier has.

[18:38:46] <XXCoder> nice
[18:38:52] <XXCoder> I want to have probe someday lol
[18:40:44] <jthornton> I should get one that is repeatable lol
[18:43:03] <XXCoder> :) well everything is repeatable to certain tol ;)
[18:49:39] <jthornton> yea, this one I had to take it apart and finish putting it together so I could center the probe...
[18:50:13] <jthornton> lol print time left 8.5 hours
[18:50:22] <jthornton> that part ain't that big
[18:50:30] <XXCoder> man if theres anything that could use time accerator its 3d printer.
[18:50:42] <XXCoder> thats what your mom said jt ;)
[18:51:06] <jthornton> my mom said don't take wooden nickles lol
[18:51:17] <XXCoder> lol
[18:51:31] <jthornton> she also sang the bean song
[18:51:39] <gregcnc> different printer?
[18:51:43] <XXCoder> giant wooden copies of coins sounds like might be fun project
[18:52:14] <jthornton> me, yes I have an Ender 3 now along with the prusa clone
[18:52:27] <Tom_L> and your favorite is?
[18:52:37] <jthornton> the Ender 3
[18:52:46] <Tom_L> is it a pro?
[18:52:50] <jthornton> much less putzing around with it
[18:52:56] <jthornton> no
[18:52:57] <Tom_L> whatever you get with pro...
[18:53:20] <jthornton> I think a magnetic print thingy
[18:53:33] <Tom_L> that's about all i could gather from it
[18:53:44] <jthornton> https://www.amazon.com
[18:53:49] <jthornton> that's the one I got
[18:54:32] <jdh> Purchased 1 time.
[18:54:36] <jthornton> that and a Rpi3 and you have a nice package
[18:54:54] <XXCoder> sometimes I wish can use linuxcnc with 3d printers.
[18:55:02] <XXCoder> but then slicers is all messed up.
[18:55:05] <Tom_L> rpi3 gets you connectivity?
[18:55:10] <Tom_L> interweb...
[18:55:11] <XXCoder> no coord support. only machine coord
[18:55:23] <jdh> Tom_L: octopi
[18:55:34] <Tom_L> yes
[18:55:46] <Tom_L> plural for octopus?
[18:55:48] <Tom_L> :)
[18:56:01] <jthornton> octiprint and octipi
[18:56:29] <jthornton> I use that on the prusa clone now and it prints much better
[18:56:49] <jdh> the dripfeed seems pretty old school, but seems to work
[18:57:03] <jthornton> https://github.com
[18:57:40] <jdh> pretty trivial setup also
[18:57:53] <jthornton> aye
[18:58:05] <CaptHindsight> XXCoder: what slicing LCNC issues do you have?
[18:58:25] <XXCoder> huh?
[18:58:30] * jthornton puts on his chef hat and fires up the bbq pit
[18:58:52] <CaptHindsight> XXCoder> but then slicers is all messed up.
[18:59:06] <XXCoder> oh like slic3r, etc
[18:59:14] <CaptHindsight> you mentioned the above
[18:59:22] <XXCoder> in view from machinist. it doesnt use g54 etc
[19:00:35] <CaptHindsight> XXCoder: well you have to understand how that evolved
[19:00:47] <XXCoder> i know. i still call it messed up lol
[19:01:48] <CaptHindsight> a bunch of know-it-alls decided to reinvent the wheel, without understanding what they were doing and what is down the road
[19:01:55] <CaptHindsight> now they defend it
[19:02:18] <XXCoder> I hate how stl is standard. it has no curves and arcs!
[19:02:29] <CaptHindsight> mostly applies to toy electronics anyway
[19:02:31] <XXCoder> so holes and curves is disorted by fitting strights
[19:02:56] <XXCoder> moreover, some firmwares g2 g3 is really bunch of g1s hidden in it
[19:03:18] <CaptHindsight> nobody building production printers used any of it
[19:03:25] <XXCoder> I keep telling them about linuxcnc true arc programming and guy "invented it" there
[19:05:10] <CaptHindsight> many are very anti-LCNC
[19:05:25] <CaptHindsight> anti-PC
[19:05:37] <XXCoder> quite a bunch have "not invented here" syndome too
[19:05:47] <CaptHindsight> like they are only are allowed to use a microcontroller as their religion
[19:06:09] <CaptHindsight> and end up in a corner
[19:06:37] <CaptHindsight> opps we didn't think of that and run out of cpu cycles
[19:07:10] <XXCoder> lol this guy had worm gear driven extruder
[19:07:19] <XXCoder> needed 2500 steps to extrude 1 mm
[19:07:27] <XXCoder> and wondered why it kept failing
[19:07:35] <XXCoder> well your 8 bit cpu got overloaded,
[19:08:27] <CaptHindsight> servo, whats that?
[19:09:09] <CaptHindsight> well most of the toys just rattle apart anyway
[19:09:33] <CaptHindsight> how many FDM machines are still around from 5 years ago?
[19:09:43] <XXCoder> I know of one
[19:09:52] <CaptHindsight> they build and buy for a bit
[19:09:59] <XXCoder> but yeah though people tend to stop after a while anyway
[19:10:09] <XXCoder> pla gets brittle with age and breaks
[19:10:18] <CaptHindsight> pump out some parts then it's in the closet or basement
[19:10:45] <CaptHindsight> now that manufacturing has been revolutionized :)
[19:13:28] <XXCoder> it is, just that people keep misappling it
[19:14:12] <CaptHindsight> I'm using LCNC for everything
[19:14:29] <XXCoder> including driving your car?
[19:14:41] <CaptHindsight> my cat drives me
[19:16:21] <XXCoder> crazy? ;)
[19:20:46] <cerna> Hmm, peole are protective of their own. I see no problem with that.
[19:22:30] <CaptHindsight> yeah, it's a real crisis
[19:23:52] <gregcnc> boring? https://www.instagram.com
[19:24:38] <CaptHindsight> gregcnc: i was nearby woodfield yesterday when the news broke...
[19:25:24] <gregcnc> lol crazy
[19:25:25] <CaptHindsight> a few hours later i was the Walmart and just minutes before a car drove through the door there as well
[19:25:41] <gregcnc> in CL?
[19:25:50] <CaptHindsight> I was worried about where to go next? yes
[19:26:08] <gregcnc> taking your chances
[19:26:09] <CaptHindsight> side door / auto center service desk
[19:27:55] <gregcnc> dang, piles of rain again
[19:28:23] <CaptHindsight> anything other than hot is fine by me
[19:40:28] <CaptHindsight> looking for suitable linux boards to use for a car stereo
[19:41:27] <CaptHindsight> an ARM tablet that uses u-boot and open kerenl source would be handy with USB ports
[19:42:11] <CaptHindsight> not really happy with the Rpi's
[19:52:03] <t4nk-freenode> so I've been messing with them there old inkjet printers again.. wanted to test the linear encoder strip on the carriage, so I demolished the encoder straight off ;).. so my whole experiment was over. Then I took the entire printer apart, I replaced the broken encoder with the encoder from the paper feed motor. Then I tried putting the motor, belt, carriage and encoder strip back in place.. this worked
[19:52:16] <t4nk-freenode> nice story, but now the remarkable thing;
[19:53:06] <t4nk-freenode> when everything was one whole, I had an h-bridge setup and steered the carriage up and down for equal amounts of time
[19:53:19] <t4nk-freenode> but now that I've reassembled it myself..
[19:53:33] <t4nk-freenode> the carriage tends to drift to one end
[19:54:20] <t4nk-freenode> so with equal amounts of driving the belt.. the carriage now does not stay in the same position
[19:54:32] <t4nk-freenode> what could do that?
[19:56:53] -!- infornography has quit [Quit: Mothra Dies at the end]
[20:01:14] <t4nk-freenode> it slowly moves to one end and starts slamming into it ;)
[20:02:06] <t4nk-freenode> now, if I reverse the leads of the motor to my h-bridge, it still drifts to the same side, but takes a bit longer to do so
[20:03:25] <t4nk-freenode> was wondering if it was a known mechanical issue, or perhaps my h-bridge is not swithing in the same way anymore
[20:04:01] <t4nk-freenode> well, nehow, let's see if I can demolish the new encoder too ;)
[20:04:04] <t4nk-freenode> *sigh*

[20:17:03] <t4nk-freenode> mmzz
[20:18:20] <t4nk-freenode> well.. it's almost exactly the same encoder, I'm giving it 3.3v and I think the little pcb it's on has the current limiting resitor on it
[20:21:23] <t4nk-freenode> it has 4 lines, I'm assuming I got it powered correctly because one of the 2 remaining leads shows +2.2v and 0v when I move it
[20:21:38] <t4nk-freenode> but the other line seems to stay high all the time
[20:21:59] <t4nk-freenode> wasn't it supposed to be opposite to the first channel?
[20:26:29] <CaptHindsight> A bus leaves Seattle going 50 mph and another bus leaves NY going 60 mph, what is the weight of the drivers if the bus only stops once to swap drivers?
[20:27:55] <CaptHindsight> what should the reader assume and show your work
[20:32:23] <t4nk-freenode> if there were anything you mighttaseen, youddaseen it?
[20:32:51] <t4nk-freenode> there are 2 issues,
[20:32:59] -!- gregcnc has quit [Remote host closed the connection]
[20:33:36] <t4nk-freenode> one; is there any known situation when one is using a dc motor and a belt, and the system is out of balance like I described
[20:34:18] -!- cradek has quit [Read error: Connection reset by peer]
[20:34:51] <t4nk-freenode> and two; linear encoder with 4 leads.. +, - channel a and channel b presumably; did anyone ever come across an encoder where only channel a outputs, and the other channel stays constant
[20:40:06] <t4nk-freenode> you got any experience with reading encoders, CaptHindsight?
[20:57:30] <t4nk-freenode> ah well, I guess I could use just the one channel, since I know the direction
[20:58:20] <t4nk-freenode> logic analyzer shows no movement on the second channel
[20:59:26] <t4nk-freenode> if anything, just a very slight fluctuation in voltage.. nothing digital at least
[20:59:49] <t4nk-freenode> 180 pulses per inch
[21:00:52] <t4nk-freenode> heh, that's funny.. almost the same resolution as my minicnc ;)
[21:11:52] <t4nk-freenode> https://www.reddit.com this is the same question
[21:15:50] <_unreal_> finally
[21:15:59] <_unreal_> just finished putting the computer back together
[21:16:22] <_unreal_> I was given an envy23 from work. i5 2.8ghz 8gb ram etc... but they cracked the touch screen
[21:16:27] <_unreal_> lcd is fine
[21:17:29] <_unreal_> WHAT a bitch to get into the thing. I spent a huge amount of time taking the thing apart. I'll have to again when I get a new touch bezel. after taking the entire thing apart I found that all I needed to do was to open the motherboard cover and pull a wierd looking cable that said TPUSB
[21:17:38] <_unreal_> touch panel usb heh
[21:17:52] <_unreal_> strange looking connector
[21:18:22] <_unreal_> so NOW maybe I can boot the computer and get it to function. before it was going crazy with touch screen touches
[21:22:38] <_unreal_> t4nk-freenode, generally all opto encoder are quadrature encoders. and all function the same way. "standard" with the 4 wires + - A B http://www.creative-robotics.com
[21:23:15] <_unreal_> +/- = 5v power and ab encoder sequencers
[21:24:07] <_unreal_> or 1 0, 1 1, 0 1, 0 0
[21:25:01] <_unreal_> t4nk-freenode, the other option is a magnetic encoder
[21:25:28] <t4nk-freenode> pffff, it's from a printer unreal..
[21:26:05] <_unreal_> yes. I assume your looking at a large PLASTIC disk part of the paper feed
[21:26:16] <_unreal_> and the strip encoder
[21:26:52] <_unreal_> both are the same encoder just different design. "disk" and "strip" both quadrature
[21:27:28] <_unreal_> only down fall is that its open and exposed to dust.
[21:32:28] <_unreal_> As to the computer. and the good news I only got two cuts from the @#$!@#$!@$# glass touch panel
[21:32:37] <_unreal_> at least is working now
[21:33:15] <_unreal_> I'm going to set it up with win10 clean setup as a windows realtime and linux realtime. going to setup both controllers on it

[22:12:06] <elmo40> win10 realtime?
[22:12:16] <elmo40> where do you get that kernel?
[22:12:51] <XXCoder> windows embedded version probably
[22:13:01] <XXCoder> tend to require special licensing?
[22:14:47] <elmo40> i don't think you can simply buy that from their website.
[22:15:16] <XXCoder> definitely.
[22:15:17] <elmo40> usually OE companies use them for embedded devices (Mazak machines use winXP w/ realtime)
[22:15:31] <elmo40> and you most likely need to purchase 10,000 licenses...
[22:18:17] <elmo40> although, you can get windows for the raspi
[22:18:22] <elmo40> i think i read that somewhere...
[22:18:34] <elmo40> i wonder if they'd use a realtime kernel for that

[22:50:12] <Tom_L> 3rd party realtime
[22:50:45] <elmo40> then again, it is smaller than the 'full' Raspbian distro at 1.2Gb
[22:51:25] <elmo40> Tom_L, i wonder what that costs
