20:40 rue_shop2 http://tom-itx.no-ip.biz:81/~webpage/avr/Toasteroven/
20:40 rue_shop2 that code?
20:41 Tom_L just a sec
20:41 Tom_L no it's in his original file
20:41 Tom_L dunno why i took it out
20:41 rue_shop2 oh
20:42 Tom_L all he changes it ckdiv8 so it runs at 8mhz
20:42 rue_shop2 I had the led in wrong
20:42 rue_shop2 :D
20:42 m_L slaps rue_s
20:42 rue_shop2 :)
20:42 Tom_L set lfuse 0xE2 (INTERNAL OSC 8Mhz... turn off CKDIV8)
20:42 Tom_L that's it.
20:46 Tom_L http://tom-itx.no-ip.biz:81/~webpage/rue/reflow2.c
20:47 rue_shop2 this source says its newer
20:47 rue_shop2 I have v1.0.1
20:48 rue_shop2 when doe sthe indicator turn on?
20:49 Tom_L what indicator?
20:49 rue_shop2 the led
20:49 Tom_L i don't recall ever using the led :D
20:49 rue_shop2 hahaha
20:49 Tom_L that kinda surprised me to see it there
20:49 Tom_L maybe it was just good intentions
20:51 Tom_L i defined the pin
20:51 Tom_L apparently never used it
20:51 Tom_L #define INDICATOR_PIN (PD6) // Verified with Board
20:51 Tom_L #define INDICATOR_PORT PORTD
20:51 rue_shop2 heh, I dint' check
20:52 rue_shop2 tells me to wire up the LED, I wire up the LED!
20:52 Tom_L probably something he and i talked about but never got around to
20:52 Tom_L you gotta hold the button .25 sec
20:52 Tom_L to start
20:53 rue_shop2 its a good thing i have a 0.42 second patience or i'd have to change the code
20:53 rue_shop2 hmm
20:54 rue_shop2 thermal calibration is out
20:54 Tom_L if you get tired of waiting just lean on the button and wait
20:54 rue_shop2 or I have one hell of a fever
20:54 Tom_L not enough to mess it up
20:54 rue_shop2 it says I'm 42c
20:54 rue_shop2 I'm pretty sure I'm thirty-something
20:54 Tom_L do you have the internal reference set to 1.1v?
20:54 rue_shop2 dosn't the code do that
20:55 Tom_L it should
20:55 rue_shop2 I have the decoupling cap across the AVCC
20:55 Tom_L ADMUX = (1<<REFS0)|(1<<REFS1)|(OVEN_TEMP); // 1.1V external cap at AREF
20:56 rue_shop2 oh I could have just used the 88?
20:56 Tom_L what did you use?
20:56 rue_shop2 168
20:56 rue_shop2 you said to
20:56 Tom_L yes
20:56 Tom_L i said 48 88 168 328
20:56 rue_shop2 goes down to 48 eh?
20:56 Tom_L whatever you wanna use
20:56 rue_shop2 dont have any 48 tho
20:57 Tom_L the code is small
20:59 rue_shop2 hmm ok
20:59 e_shop2 th
20:59 Tom_L i didn't check the temp on the pt100
21:00 Tom_L it melted solder so i was happy with it
21:00 rue_shop2 yours is pt100 yes?
21:00 Tom_L yes
21:00 Tom_L it didn't melt the oven so it wasn't too hot
21:00 Tom_L i stuck it on a board and stuck the board to the side of the oven with RED RTV
21:00 rue_shop2 ok, well I'm feeling success
21:00 Tom_L so it wouldn't fall off
21:01 Tom_L i got the chips off those boards
21:01 Tom_L he was gonna send me some more but i haven't caught up with him yet
21:01 Tom_L i may buy a new pair as a backup
21:02 Tom_L once i can
21:02 rue_shop2 hmm
21:02 rue_shop2 its too bad its not just a nice disposable arduino board
21:02 Tom_L they got a new board out with 72 io instead of 48 for much less than i paid for mine
21:03 Tom_L newer, better, more io, cheaper
21:03 Tom_L http://store.mesanet.com/index.php?route=product/product&filter_name=7i90&product_id=291
21:04 Tom_L http://store.mesanet.com/index.php?route=product/product&filter_name=7i43&product_id=67
21:04 Tom_L the one i have ^^
21:04 rue_shop2 ah the interrupt does the screen
21:05 Tom_L the other one has 3 50pin headers
21:05 Tom_L oh you're switching to cereal io?
21:05 rue_shop2 maybe...
21:05 Tom_L if you did it, that would be the board to get
21:05 rue_shop2 I dont want to put a micro on the lcd, as nice a generic module as that makes
21:05 Tom_L they are very nice
21:06 rue_shop2 if I put a shift reg on the lcd I can use the serial for talking to it
21:06 Tom_L and i'm getting pretty decent at making config files for them
21:06 rue_shop2 but I'm not supposed to mod it right now
21:06 Tom_L how come?
21:06 rue_shop2 get it working, then hack it
21:07 rue_shop2 its ideal, but I'm trying
21:07 Tom_L oh
21:07 Tom_L that doesn't sound like you
21:07 rue_shop2 ITS HARD
21:07 Tom_L i made all those boards and now nobody wants them again
21:08 rue_shop2 lots of effort to stick a sock in it till I'm standing in a place where I have some ground to say everything is silly
21:08 rue_shop2 oven baords?
21:08 rue_shop2 programmers?
21:08 Tom_L programmers
21:08 rue_shop2 ugh
21:08 Tom_L good i did before i blew up the mill
21:08 rue_shop2 do yo uhave boxes done for them?
21:08 Tom_L a few
21:08 rue_shop2 good show
21:08 Tom_L i forgot how many
21:08 rue_shop2 3 or 4 hundred?
21:09 rue_shop2 :)
21:09 Tom_L oh hell no
21:09 Tom_L maybe a dozen or two
21:09 rue_shop2 hmmm
21:09 Tom_L i don't remember
21:09 rue_shop2 I can spot weld, so I can modify the existing oven
21:09 Tom_L i got a sack full of boxes though
21:09 Tom_L ready to mill
21:09 rue_shop2 (spot welded solid wire in it)
21:10 rue_shop2 or use the newer plastic capped one I gutted and preped (damn near rebuilt it)
21:10 Tom_L http://store.mesanet.com/index.php?route=product/product&filter_name=7i47&product_id=98
21:10 rue_shop2 or the newer metal one thats already micro controlled
21:10 Tom_L that was the other board
21:11 rue_shop2 what are the advantages of those baords?
21:11 Tom_L alot more IO and alot faster step rates
21:11 Tom_L and
21:11 rue_shop2 you can upload hardware controllers?
21:11 Tom_L you can interface SSERIAL to it and get oodles of IO
21:11 Tom_L ?
21:11 Tom_L what do you mean?
21:11 Tom_L the onboard fpga has functions built in it
21:11 rue_shop2 cause you can just add another serial system to the fpga, yes?
21:12 Tom_L you write pin files to bring them out
21:12 rue_shop2 hmm
21:12 Tom_L yes you can
21:12 Tom_L and each serial pin supports 7 boards
21:12 Tom_L you can have virtually unlimited io
21:12 rue_shop2 whats the microstepping level on the drivers?
21:12 Tom_L there comes a point it's too slow though
21:13 Tom_L the new ones run at 200Mhz i think
21:13 Tom_L mine runs at 50Mhz
21:13 Tom_L you'd have to ask him
21:13 rue_shop2 no I mean your stepper drivers
21:13 rue_shop2 the gecko
21:13 Tom_L oh.
21:13 Tom_L 10
21:13 rue_shop2 10!?
21:14 Tom_L no other settings available
21:14 rue_shop2 strange number
21:14 Tom_L but
21:14 Tom_L it's got a dsp built in to smooth it all out
21:14 rue_shop2 I expected 8 or 16
21:14 rue_shop2 yea
21:14 Tom_L they're real nice
21:14 rue_shop2 Iknow
21:14 Tom_L i'm not sorry i spent that money
21:14 rue_shop2 I'v seen the reverse module from them
21:14 Tom_L ?
21:14 rue_shop2 step/dir in, operates dc motor with encoder
21:15 Tom_L oh the servo version?
21:15 rue_shop2 yea
21:15 Tom_L yeah
21:15 Tom_L i wish i could afford servos
21:16 rue_shop2 my new cnc is gonna be dc with enocders
21:16 rue_shop2 linear encoders
21:16 rue_shop2 compensate for junk
21:16 rue_shop2 I shoudl get on that
21:16 rue_shop2 its 98% set up for the test of the Y axis
21:18 Tom_L i will say i don't like their screw terminals on them though
21:18 Tom_L they are removable and with decent wires on them they flex on the pin and can disconnect
21:19 rue_shop2 hmm
21:20 Tom_L i switched the wire out for a little smaller and they work fine now
21:20 rue_shop2 why is there ferinheight on here?
21:20 Tom_L i was trying to get it to display right but never figured it out
21:21 rue_shop2 oh its target
21:21 Tom_L needed it to get working so i abandoned it
21:21 rue_shop2 I wonder what degrees is on those displays...
21:21 Tom_L it doesn't get any hotter in farenheit than celsius
21:22 Tom_L i never use this lathe package
21:22 Tom_L i'm trying to figure out a few bits about it
21:23 rue_shop2 0xDF
21:23 Tom_L i coded one successfully for a brit
21:23 Tom_L i wonder if i can find it...
21:26 Tom_L https://www.youtube.com/watch?v=oye3BxqXKmw
21:27 Tom_L i programmed that for him
21:32 Tom_L https://www.youtube.com/watch?v=IOBxmGZR3j0
21:34 rue_shop2 hmm
21:35 rue_shop2 hey it went to stage 2 without hitting the target of stage 1
21:35 Tom_L i think the first is just timed
21:35 Tom_L bake off
21:36 rue_shop2 hmm yea
21:36 Tom_L to clear out the humidity in the chip
21:36 rue_shop2 if its still 30c...
21:36 rue_shop2 ok anyhow
21:37 Tom_L how many irc'rs have you met?
21:38 rue_shop2 hmm
21:38 rue_shop2 rifraf, thebear
21:38 Tom_L the video me think of that
21:38 rue_shop2 are the major ones
21:39 Tom_L i've met several when they came to the linuxcnc fest last year
21:39 rue_shop2 oh, the guy
21:39 rue_shop2 whats his face
21:39 Tom_L he was one ^^
21:39 rue_shop2 oh, well amyofevilrobots
21:39 rue_shop2 but, the other guy
21:39 rue_shop2 danf
21:39 rue_shop2 no
21:40 Tom_L no not him!
21:40 rue_shop2 danroyer?
21:40 rue_shop2 marginally clever software, that guy
21:40 rue_shop2 dan soemthing
21:40 rue_shop2 not the guy who never builds anything
21:40 Tom_L yeah that's danf
21:40 rue_shop2 ah
21:41 Tom_L the one talking about his electric car
21:41 rue_shop2 thats the basic list
21:41 rue_shop2 no
21:41 rue_shop2 that guy was in germany
21:41 Tom_L that's danf
21:41 rue_shop2 https://www.marginallyclever.com/shop/
21:41 rue_shop2 ^^ I met that guy
21:44 rue_shop2 ah, hmm I see why you put it in a box on top
21:46 Tom_L http://electronicsam.com/images/KandT/Fest2013/
21:47 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3813.JPG
21:47 Tom_L the far one is the brit i met
21:48 rue_shop2 cool
21:48 Tom_L most of the authors of linuxcnc were there
21:49 rue_shop2 :)
21:49 rue_shop2 I plan to get into the states one day and swing by your place
21:50 Tom_L you'd just be disapointed
21:50 rue_shop2 meh
21:50 rue_shop2 I need to get out more
21:50 rue_shop2 the destination is less important than the experience
21:51 rue_shop2 but I'm too worried about getting killed
21:51 Tom_L most of us are decent
21:51 rue_shop2 I seeing as I can only do it once I'm into making it something special
21:51 Tom_L it's the few you hear about in the news that make us all look bad
21:52 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3854.JPG
21:52 rue_shop2 I'm comming to the conclusion that I want to make the thermal controller a seperate box that the oven plugs into
21:52 Tom_L the guy with that wouldn't shut up
21:52 rue_shop2 figures
21:52 rue_shop2 he sued the expensive stuff
21:53 Tom_L he was running it on linuxcnc on a bbb
21:53 rue_shop2 he hasn't had it long
21:53 rue_shop2 I see a mega2560
21:54 rue_shop2 hmmm
21:55 rue_shop2 and so it starts, the search for the perfect project box
21:56 rue_shop2 not too big, not too small
21:56 rue_shop2 not to deep
21:56 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3861.JPG
21:56 rue_shop2 hmmm
21:56 Tom_L the guy in orange owns the place
21:56 Tom_L got a nice tour of his cnc shop
21:56 rue_shop2 a UPS case perhaps
21:57 Tom_L you've seen the cincinatti 5 axis on youtube
21:58 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3864.JPG
21:58 Tom_L he's one of the 'serious' coders
21:59 rue_shop2 huh
22:00 Tom_L most of the guys in the 'conference room' were
22:00 rue_shop2 I need to make a proper brake
22:00 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3874.JPG
22:00 Tom_L that bunch
22:01 rue_shop2 its nice to know there are pasionate people paving the way for the (less) average joe
22:01 Tom_L http://electronicsam.com/images/KandT/Fest2013/DSC_3876.JPG
22:01 Tom_L the ole guy in the center was one of the original authors
22:02 Tom_L i missed pete from mesa
22:02 Tom_L he came the next day after i was gone
22:03 Tom_L ( the boards i have )
22:06 Tom_L i offered a suggestion that made it into 2.6 :)
22:08 rue_shop2 DE1824
22:08 rue_shop2 ..
22:09 rue_shop2 sweet
22:09 rue_shop2 what was it?
22:09 rue_shop2 1824 is a hub, perfect
22:09 e_shop2 gut
22:11 Tom_L just a simple code addition
22:11 Tom_L for a hard button on a pendant for pause/resume
22:11 Tom_L it was only on the pc screen up to that point
22:20 rue_shop2 cool
22:27 Tom_L if (h.change_button):
22:27 Tom_L h.changed = True
22:27 Tom_L app.update()
22:27 Tom_L app.tk.call("set", "::tkPriv(button)", -1)
22:27 Tom_L stop_polling_hal_in_background()
22:27 Tom_L return
22:27 Tom_L that's all
22:29 Tom_L i forgot what i was doing
22:48 Tom_L this takes some getting used ti
22:48 Tom_L to
22:49 Tom_L in lathe, you enter a diameter value and it displays as a radius
22:49 Tom_L but half is above 0 and half below
22:49 Tom_L in mill i'm not used to thinking that way
22:49 Tom_L then you gotta know the standard insert cutter dimensions
22:50 Tom_L like DNMG203
22:50 Tom_L each letter designates something about it
22:50 Tom_L which the cad cam knows and will display
22:52 Tom_L http://www.kennametal.com/content/dam/kennametal/kennametal/common/Resources/Catalogs-Literature/Metalworking/Master%20Catalog%20-%20Inch%20Sections/A-11-02679_MasterCat_stationary_ISO_ANSI_inserts_inch.pdf#page=2&zoom=auto,23,879
23:24 rue_more I wonder if that expalains...
23:25 rue_more rue_shop2, 85mm square
23:25 Tom_L ?
23:28 rue_more https://www.kmstools.com/magnum-3-8-carbide-insert-2963
23:28 rue_more they seemed to ahve rounded edges
23:29 rue_more CIT38
23:30 rue_more its all mixed up
23:30 rue_more the T is for triangle
23:30 rue_more the C must mean 7 degrees
23:33 rue_more or the C is for coated carbide
23:35 Tom_L http://www.carbidedepot.com/formulas-insert-d.htm#shape
23:35 Tom_L that's a good one for explinations
23:36 rue_more I gave up ont eh inserts, I kept chipping them
23:36 rue_more I'm better off to just buy hss
23:36 rue_more unless I have soemthing I need the carbide for
23:37 Tom_L i just need it for the dimensions
23:37 Tom_L to enter in the tool table
23:37 rue_more this is a really detailed doc...
23:38 Tom_L http://www2.coromant.sandvik.com/coromant/pdf/Metalworking_Products_061/tech_a_5.pdf
23:39 rue_more https://www.kmstools.com/magnum-3-8-carbide-insert-2963 <-- these are the cheap ones, I fer to think what the ones in that doc cost
23:39 Tom_L we had some that were tough as nails
23:40 rue_more they are brittle tho
23:40 Tom_L made to abuse
23:40 Tom_L i don't know what they were but they were very tough
23:40 rue_more huh
23:40 Tom_L i used them alot for making round test specimens for the aircraft
23:40 rue_more then again, I doubt I'v ever worked with anything but the cheap ones
23:40 Tom_L they took them back and pulled until they broke
23:41 Tom_L we did flat ones too
23:41 Tom_L both grain direcions of the material
23:41 Tom_L usually 6 each
23:42 rue_more yup
23:45 rue_more I know guys who used to slip the occasional peice of rebar into the cement cylinders used for concrete tests
23:45 rue_more :)
23:45 Tom_L kinda defeats the purpose
23:45 rue_more :) they said the results were amusing
23:45 rue_more testers dispised them
23:45 rue_more :)
23:46 rue_more something is wrong with my head
23:47 rue_more my thinking is off
23:54 Tom_L sleep
