12:06 AM Contract_Pilot: Another user bricked tormach ECM Board inbound! I don't see how people keep bricking them LOL. The Last one was a H2M communication error dead 93C46. Fun times!
12:14 AM XXCoder: cant unbrick?
01:58 AM randy: morning
02:03 AM randy: "really you only need mesaflash if the default firmware is not what you need" - the first thing i did with the brand new 7i92 was to change the firmware :) but "only" because i already had a pinout on my maschine for the current controller and i wanted to align the P2 to it ;)
02:03 AM randy: it's "fun" working with the old ISE building new bitfiles
02:26 AM Deejay: moin
03:52 AM -!- #linuxcnc mode set to +v by ChanServ
04:27 AM -!- #linuxcnc mode set to +v by ChanServ
05:34 AM JT-Cave: mornint
05:34 AM JT-Cave: you gotta love it when people quote only part of what you say and leave off the important part
06:28 AM -!- #linuxcnc mode set to +v by ChanServ
08:41 AM serp: "you gotta love it when people quote only part of what you say" -- JT-Cave
08:48 AM CaptHindsight[m]: gotta
09:35 AM randy: JT-Cave: well, i uoted the part on which i wanted to reply. but you are totally right - 99% the default firmware is enough and mesaflash more ore less not needed (beside of of checking "is the card alive & accessable)"
11:02 AM JT-Shop: <JT-Cave> really you only need mesaflash if the default firmware is not what you need and 99% of the time for cards like 7i96 etc the default firmware is fine
11:02 AM JT-Shop: however you usually have to flash a 5i25 type of card
11:29 AM roguish[m]: gonna be in the 90's today............
11:31 AM CloudEvil: It seems like thirty years since it was last in the 90s.
11:38 AM roycroft: it's going to be nice here today
11:38 AM roycroft: sunny and a high of 24
11:39 AM roycroft: tomorrow was supposed to be rainy, but the forecast has changed to another sunny day
11:39 AM roycroft: which will be nice - i'm on vacation tomorrow
11:39 AM roycroft: so i should be able to get some outdoor chores done, but i have a booster vaccine appointment in the morning, so we'll see how that goes
11:39 AM roycroft: i'll probably feel like crap on saturday, though, not friday afternoon
12:17 PM coralgoat: I am shopping for a PCI express serial port card (for a Linuxcnc x86 desktop) and a serial male to serial male cable specifically for Linuxcnc.
12:18 PM coralgoat: Are there any specific gotchas for these two parts that I should be aware of in the context of Linuxcnc?
12:30 PM roycroft: my pid controller is due to arrive today
12:31 PM roycroft: the enclosure and some of the other parts are not due until this weekend, but i can at least check out/calibrate the thermocouple i just installed by setting the pid controller on the bench
12:49 PM unterhaus_: coralgoat, if you need real time performance from the serial port, you will likely have to program it yourself
12:52 PM enleth: do you know what to search for to order this style of aluminum extrusion? https://x0.at/kxiQ.jpg https://x0.at/iC8p.jpg https://x0.at/1QNv.jpg
12:53 PM enleth: this specific example is a server PDU, I imagine they would be used for industrial light fixtures to
12:53 PM enleth: *too
12:58 PM coralgoat: unterhaus_, when you say "if you need real time performance from the serial port, you will likely have to program it yourself" do you mean that I will have to configure Linuxcnc with Stepconf? Or are you referring to some other kind of programming?
01:04 PM coralgoat: Information about the CNC router I am trying to get working is logged here starting at 09:59 AM:
01:04 PM coralgoat: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2022-03-29.html
01:15 PM unterhaus_: mach 3 usb ... etc ... is not really a good start for linuxcnc
01:16 PM unterhaus_: coralgoat, it looks like you need a parallel port card
01:30 PM roycroft: somebody needs to start making fpga chips again so that pcw can make mesa cards again, providing him with an income and providing the cnc community with the hardware they need to build their machines properly
01:30 PM * roycroft is just saying
01:46 PM FinboySlick: enleth: Not quite the same but I think this would be a good starting point: https://www.kanya.com/en/products/extrusion-connecting-system/33-07062019-093027/c38-11-02-02-200.html
02:00 PM unterhaus_: apparently people were planning on building chip fabs in the U.S. even before the pandemic
02:01 PM satiowadahc[m]: soon... https://hackaday.com/2018/04/24/first-lithographically-produced-home-made-ic-announced/
02:02 PM unterhaus_: I have a batch of chip fab equipment in my junk pile, but not enough to make chips
02:06 PM CloudEvil: Did I link https://www.youtube.com/watch?v=LjDUROWxT7k here? This is a fab 3 miles from me, that has a working 30 year old fab.
02:06 PM CloudEvil: (And newer ones)
02:06 PM CloudEvil: Tour around all the machiens by the MD that started it.
02:07 PM CloudEvil: Inc LCD retrofit screens duct-taped to things.
02:08 PM unterhaus_: on a similar subject, it turns out that some companies didn't actually throw away their tube building equipment, they just stopped using it
02:08 PM CloudEvil: GE?
02:09 PM CloudEvil: I'd wondered if that was actually the case.
02:09 PM CloudEvil: As, where the actual fuck would you source tube making equipment in 2022. (other than from russia)
02:09 PM CloudEvil: Is that more than supposition?
02:10 PM unterhaus_: I saw a discussion, no links
02:10 PM unterhaus_: but someone said that one of the U.S. companies had announced they would resume making tubes
02:11 PM CloudEvil: Yes, they have.
02:12 PM unterhaus_: western electric says they are expanding
02:15 PM t4nk_freenode: heh, I'm actually getting better at this! I cut some more square tubes, marked them, punched them
02:15 PM t4nk_freenode: getting ready to drill
02:18 PM Tom_L: by the time you're done you'll be a pro
02:19 PM Tom_L: unterhaus_, due to the chip shortage?
02:31 PM CloudEvil: Tom_L: no
02:31 PM CloudEvil: Tom_L: Due to being unable to source parts for audiophile stuff from russia
02:31 PM Tom_L: mcintosh still makes tube amps don't they?
02:33 PM t4nk_freenode: 3mm holes are done
02:34 PM t4nk_freenode: need to get them up to 10mm now, gonna try it in one go
02:34 PM t4nk_freenode: time to start watching my foot ;)
02:35 PM t4nk_freenode: yeah, well, I keep coming up with new ways of doing things, and they are big improvements.. so then I wonder why on earth I hadn't thought of them before
02:38 PM t4nk_freenode: yeah, Tom_L, I'll be a pro when I'm done; probably gonna have to do it all over again too before it's done :b
02:39 PM t4nk_freenode: but it's a nice way to spend the nights
02:49 PM t4nk_freenode: LOL
02:49 PM t4nk_freenode: I thought my drill had gone immensely blunt all of a sudden
02:50 PM t4nk_freenode: .... took me a while to realize it was set to reverse :b
02:50 PM satiowadahc[m]: just needs more cutting fluid then right?
02:59 PM -!- #linuxcnc mode set to +v by ChanServ
03:06 PM Tom_L: running it in reverse won't undo a missplaced hole ya know
03:06 PM XXCoder: would be amazing if we had reverse time
03:06 PM XXCoder: oops miscut, reverse time around machine till its undone and fix setup
03:07 PM satiowadahc[m]: iirc, someone programmed in a undo gcode last april fools day...
03:18 PM MrSunshine_ is now known as MrSunshine
03:33 PM roycroft: so jet still don't have a table for my bandsaw, and there is no estimated date for getting any
03:33 PM roycroft: and now the saw is on sale
03:33 PM roycroft: i've asked for a rebate on mine, since i've not been able to use it since i bought it, and now it's on sale
03:33 PM roycroft: and i still cannot use it
03:34 PM roycroft: they don't seem to care that i can't use it
03:34 PM roycroft: they do care that i bought it, and are happy that i did
03:34 PM FinboySlick: roycroft: Did you buy it with a credit card?
03:34 PM roycroft: yes
03:34 PM roycroft: but it's been five months now
03:34 PM roycroft: it's too late to get a remedy through the merchant bank
03:35 PM FinboySlick: My visa gives me a year extra warranty on any purchase.
03:35 PM roycroft: five months and two warped tables later, and it still sits in the shop unable to be used
03:35 PM FinboySlick: You might have something similar that could help put pressure on them.
03:35 PM roycroft: oh, i have a warranty on it
03:35 PM roycroft: they just don't have any parts for it
03:35 PM roycroft: they will send me another table whenever they get more
03:35 PM roycroft: but there's no telling when that will be
03:36 PM roycroft: and since i've had three warped tables so far, i don't have a lot of confidence that the next one will be flat
03:36 PM roycroft: the problem is that when they cast the tables, they should toss them out in the back lot for a year or so before they machine them and install them
03:36 PM FinboySlick: There's a pretty lovely planer/jointer combo I'd love to get. Since you do wood a bit more, what would your argument be against a combo planer/jointer?
03:36 PM roycroft: instead, in this dat of jit manufacturing, they machine it as soon as it's cool enough to handle
03:37 PM roycroft: i almost bought one last year
03:37 PM roycroft: i had a 6" jointer and a 15" thicknesser
03:37 PM roycroft: i wanted a bigger jointer
03:37 PM FinboySlick: https://www.busybeetools.com/products/12in-jointer-planer-combo-helical-rikon.html?utm_source=April4_2022-25210H&utm_medium=email&utm_campaign=25210H%20Special%20Buy looks pretty nice.
03:37 PM roycroft: i was looking at an 8" jointer
03:37 PM roycroft: but then i started looking at a combo machine
03:38 PM roycroft: because it would save space, and because i could flatten wider boards easily
03:38 PM roycroft: a 12" combo machine might have worked nicely for me
03:38 PM FinboySlick: Yeah, that was my thinking too.
03:38 PM t4nk_freenode: done, and the place is cleaned up too.
03:38 PM FinboySlick: Looks pretty sturdy too.
03:38 PM roycroft: the advantages are that i could flatten wider boards and save space, as i said
03:39 PM roycroft: the disasvantages are that the jointer bed is shorter, so it's harder to flatten severly warped boards, and the thicknesser would go from 15" to 12"
03:39 PM FinboySlick: I imagine the jointer and planer adjustments are separate so you can use one without messing with the other.
03:39 PM roycroft: but at the time, there were no combo units available from anyone, so i ended up buying the 8" jointer
03:39 PM roycroft: sort of
03:39 PM roycroft: the thicknesser bed is below the cutter
03:40 PM FinboySlick: Curious to see how their helical carbide insert heads work too.
03:40 PM roycroft: so you can leave it set to whatever height you want
03:40 PM roycroft: and the jointer beds maintain their alignment
03:40 PM roycroft: to convert, you flip the jointer beds up, flip the dust collector chute over to the opposite side, and then start using the thicknesser
03:41 PM roycroft: on a decent unit it takes 30 seconds or less to convert back or forth
03:41 PM roycroft: i have helical heads on my jointer, both the old and the new, and on the thicknesser
03:41 PM roycroft: i would not go back to straight knives no matter what
03:41 PM roycroft: i would really love to have a 12" jointer, but no room and no money for that
03:42 PM roycroft: when i need to flatten boards wider than 8" i have a sled i can use for that
03:42 PM FinboySlick: Wow: https://cdn11.bigcommerce.com/s-9fa34wk/images/stencil/1280x1280/products/8349/11385/25210H_1__71755.1544614021.jpg?c=2?imbypass=on
03:42 PM FinboySlick: I didn't expect it to convert *that* way.
03:42 PM roycroft: i just flatten 8", and slide that part on the sled, with the unmachined bits haning down
03:43 PM roycroft: yeah, that's the normal way
03:43 PM t4nk_freenode: heh, FinboySlick ... why do I get this sudden craving for wafers
03:43 PM t4nk_freenode: ehh, waffles
03:43 PM roycroft: to joint with it, you flip the dust chute over to the left, and it sits below the jointer tables
03:44 PM roycroft: that one has the european style guard over the jointer head
03:44 PM roycroft: i like that
03:44 PM roycroft: mine has the stupid american pork chop guard
03:44 PM roycroft: i'm thinking of making or otherwise retrofitting a european style guard on mine
03:44 PM FinboySlick: Pork chop guard on a 12" jointer would be a bit unwieldy.
03:45 PM roycroft: we do some really stupid things in this country
03:45 PM t4nk_freenode: yeah, you sure do ;)
03:45 PM roycroft: and then, while the rest of the world moves on to better solutions, we cling to our stupidity, because we're 'merucans' and we do things the 'mericun' way
03:46 PM roycroft: anyway
03:47 PM roycroft: i think a combo machine could be a good solution, as long as you understand the compromises
03:47 PM roycroft: there's a very good chance i would have purchased one last year, if they were available at the time
03:48 PM roycroft: i really needed to upgrade my jointer, but the new one is over 50% larger than the old one, and it barely fits in the shop
03:48 PM roycroft: to the point that when i'm using it, i generally roll it outside in the driveway
03:49 PM roycroft: a combo machine would not have that problem in my situation
03:55 PM unterhaus_: XXCoder, I got all excited when I found out the moore I was using had reverse time mode
03:55 PM XXCoder: lol
03:55 PM unterhaus_: then I read the instructions and it doesn't work
03:56 PM unterhaus_: not that I ever messed up on that particular machine
04:06 PM acer is now known as _unreal_
04:14 PM t4nk_freenode: hi acer
04:19 PM t4nk_freenode: bye _unreal_
04:19 PM acer is now known as _unreal_
04:20 PM t4nk_freenode: hi _unreal_
04:29 PM CaptHindsight[m]: satiowadahc: fabricating IC's with 1980's tech is pretty easy and cheap using a DLP projector and microscope
04:29 PM t4nk_freenode: I had a buddy who learnt that at school
04:30 PM roycroft: i don't understand why we don't make more chips here in the usa
04:30 PM CaptHindsight[m]: Sam Zelof also has a hack a day on his setup
04:30 PM roycroft: i can give you a good example of something that makes no sense at all
04:30 PM roycroft: about 15 years ago hynix decided to build a semiconductor manufacturing plant here in eugene
04:31 PM roycroft: they got all kinds of tax breaks and other concessions from the city, as companies like that always do
04:31 PM t4nk_freenode: the chick from the c64-on-a-chip is also into that
04:31 PM roycroft: so the taxpayers spent milllions of dollars improving the road system near their plant site
04:31 PM roycroft: they spent hundreds of millions of dollars building the plant
04:31 PM roycroft: they promised 3000 local jobs when it was complete
04:31 PM roycroft: and they delivered - they build it and hired 3000 people
04:32 PM roycroft: it was a state of the art plant at the time
04:32 PM roycroft: they made chips for about 3-4 years, then closed it down
04:32 PM roycroft: laid everyone off
04:32 PM roycroft: they never stayed open the 10 years they promised the city in return for all the tax incentives
04:32 PM roycroft: so that's all weird
04:33 PM roycroft: but then the plant sat empty
04:33 PM roycroft: for years
04:33 PM CaptHindsight[m]: roycroft: because your boss isn't even close to the level of cheap that semiconductor fabs have hired
04:33 PM roycroft: then they started selling off all the equipment for scrap
04:33 PM CaptHindsight[m]: ^^ this why we don't
04:33 PM roycroft: now there's this huge, formerly state of the art chip manufacturing plant siting vacant, and rotting away
04:33 PM CaptHindsight[m]: we don't resell the old fabs, we tear them down and sell as scrap
04:34 PM roycroft: when we desperately need chip manufacturing here in the us
04:34 PM roycroft: from a consumer demand point of view
04:34 PM CaptHindsight[m]: old fabs are at 100 different ebay sellers shops :)
04:34 PM roycroft: and more importantly, from a national security point of view
04:34 PM CaptHindsight[m]: in about 5 years the US guberment will figure this out
04:35 PM roycroft: it just doesn't make sense that this can happen
04:35 PM roycroft: the us government will *never* figure it out
04:35 PM roycroft: well, actually, they figured it out a long time ago
04:35 PM CaptHindsight[m]: right now we are planning on giving Intel billions to waste on this
04:35 PM roycroft: the republicans rant about national security, but pass trade deals that outsource everything and favor the 1%
04:35 PM CaptHindsight[m]: yes F***ing Intel vs a ton of other more honest vendors
04:35 PM roycroft: and then they blame the democrats
04:36 PM CaptHindsight[m]: it works :)
04:36 PM roycroft: the democrats rant about globalization and how it will be the great equalizer
04:36 PM roycroft: and outsource everything, which favors the 1%
04:36 PM CaptHindsight[m]: it does, now it sucks for most everyone
04:36 PM roycroft: and then rant about how the 1% are destroying the country
04:36 PM CaptHindsight[m]: as planned
04:36 PM roycroft: when the truth is, the 1% are not destroying this country
04:36 PM CaptHindsight[m]: why rant, you and I don't matter
04:36 PM roycroft: the republicans are destroying this country
04:37 PM roycroft: and the democrats are destroying this country
04:37 PM roycroft: i want someone to open up the hynix plant again
04:37 PM roycroft: and make some chips and send them to pcw
04:37 PM * Tom_L gives roycroft a box to stand on
04:37 PM roycroft: so we can tell china to go bugger off
04:37 PM CaptHindsight[m]: wake me when we start to eat the rich
04:38 PM t4nk_freenode: lol, Tom_L .... I was holding back on the "Roycroft for President" :b
04:38 PM roycroft: lord no
04:38 PM roycroft: i would be just about the last person anyone would want for president
04:38 PM CaptHindsight[m]: most people don't care
04:38 PM CaptHindsight[m]: have you met most people?
04:38 PM Tom_L: naw he'd have us all making wood projects
04:38 PM roycroft: i certainly don't have the temperment for the job
04:38 PM roycroft: not that that stopped the previous president
04:39 PM CaptHindsight[m]: repeat after me"evidence shows that most people just don't care"
04:39 PM roycroft: but i at least have a semblence of self-awareness
04:40 PM CaptHindsight[m]: just look at the past 2 years of selfish and stupid with Covid
04:50 PM roycroft: selfish and stupid did not begin 2 years ago
04:50 PM roycroft: perhaps the curve got steeper then, but the pandemic cannot be blamed for that entirely
04:53 PM roycroft: i still blame new gingrich and his "contract with america", and the emergence of the tea party in 2010 as the causes of the toxic atmosphere in washington, but at this point in time, that toxicity is pretty much equal on both sides of the aisle
04:53 PM roycroft: and a lot of it has to do with selfish and stupid
04:54 PM CaptHindsight[m]: yes, but the past 2 years was just an example to highlight the fake lies
04:54 PM roycroft: we're in an era now where for many, running for congress is not even a little bit about serving or governing
04:54 PM CaptHindsight[m]: truth vs alternate lies
04:55 PM roycroft: it's just an easy way for stupid, nasty people to get a medium salary job for a couple years and then get a high paying job on fox news or msnbc
04:55 PM roycroft: people who are otherwise unemployable
04:55 PM roguish[m]: roycroft:those fucking republicans in the 'say no to everything' group back in 2012 cost me my best job, at Lawrence Berkeley National Lab.
04:55 PM CaptHindsight[m]: I like how you get to chose your facts and lies now at many levels
04:56 PM roguish[m]: That's 'designer news'
04:56 PM roycroft: someone explain to me how senator cruz is serving his country when he lambasts a supreme court nominee with a bunch of bullshit, and then doesn't even listen to her response to his "question", because he's too busy checking his twitter trend
04:57 PM CaptHindsight[m]: oh he was just playing to his base while "owning" the libs
04:57 PM CaptHindsight[m]: it's all drama
04:57 PM CaptHindsight[m]: since what matters most to the most people are their feelings
04:58 PM roguish[m]: maybe his constituents were stunted by all the lead in the water.............
04:58 PM roycroft: isn't he supposed to be serving his country by offering advise and consent to an importiant judicial nomination?
04:59 PM roycroft: should he not be asking serious questions to help him honestly evaluate the fitness of the nominee to serve in the appointed position?
04:59 PM CaptHindsight[m]: are you an idealistic youth?
04:59 PM roycroft: no, i'm an idealistic old man
04:59 PM roguish[m]: i was just going to say Roycoft is way to idealistic
04:59 PM roycroft: somehow, jadedness has eluded me
04:59 PM roycroft: actually i'm pretty realistic
04:59 PM CaptHindsight[m]: it's been broken for a while
05:00 PM roycroft: i don't expect politicians to act as they should
05:00 PM roycroft: but i do expect them to at least pretend to act as they should
05:00 PM CaptHindsight[m]: popular opinion has replaced facts
05:00 PM roycroft: and they don't even bother doing that any more
05:00 PM roycroft: no
05:00 PM CaptHindsight[m]: too late
05:00 PM roycroft: alternate facts are what are replacing factual facts
05:00 PM CaptHindsight[m]: it's all breads and circuses
05:00 PM roguish[m]: ya know why most politicians are attorneys?
05:01 PM roguish[m]: Politics is the only thing they can sink down to...........
05:01 PM satiowadahc[m]: because theres an unlawfully large amount of them?
05:01 PM roycroft: the current crop are not mostly attorneys
05:01 PM roycroft: take marjorie taylor greene, for example
05:02 PM CaptHindsight[m]: it could be worse, we could have more dictators running things than already are
05:02 PM roguish[m]: she's totally wack
05:02 PM roycroft: her iq is equivalent to suntan lotion
05:02 PM CaptHindsight[m]: but someone that I'd like to have a beer with, or pour one down our pants
05:02 PM roycroft: there's no way she would even pass the lsat exam
05:02 PM roguish[m]: gene pool doesn't cover her ankles.
05:02 PM roycroft: much less endure law school and sit for the bar exam
05:03 PM roycroft: or lauren boebert
05:03 PM CaptHindsight[m]: anyone recall that big popular push starting in the 70's to put your feeling above rational thought?
05:03 PM roycroft: there's the rub
05:04 PM roycroft: schools do not teach critical thinking skills any more
05:04 PM roycroft: it's all about the feel good
05:04 PM roycroft: everybody gets a medal
05:04 PM CaptHindsight[m]: you have a large portion of the people worldwide now that place their emotions above the rational thoughts
05:04 PM roycroft: not just the winner
05:04 PM roguish[m]: ok, back to running my 8/3 wire for my new hvac system
05:04 PM roycroft: everyone is a winner now
05:04 PM roycroft: there's no incentive to excel
05:04 PM roycroft: you still get the medal
05:05 PM CaptHindsight[m]: they are far easier to mnaipulate
05:05 PM CaptHindsight[m]: manipulate even
05:05 PM roycroft: "i love the undereducated"
05:06 PM roycroft: so y eah
05:06 PM CaptHindsight[m]: they don't even try to hide it anymore
05:06 PM roycroft: yes, this is what is most insulting
05:06 PM CaptHindsight[m]: btw did you catch New Rules last friday?
05:06 PM roycroft: yes
05:06 PM roycroft: and faux news did not report on that part of the show :)
05:06 PM CaptHindsight[m]: he compared 2010 repubs to 2022
05:07 PM CaptHindsight[m]: it was great
05:07 PM roycroft: all they reported was the calling out of the hunter biden stuff
05:07 PM CaptHindsight[m]: the bat shit will get even crazier
05:09 PM roycroft: which is exactly what maher said they would do
05:09 PM roycroft: "look - even bill maher is on our side"
05:09 PM roycroft: "yeah, like 3% of the time - but the other 97% of the time i call you out on ever crazier shit"
05:09 PM CaptHindsight[m]: Eisenhower warned of the military complex back in the late 50's
05:09 PM roycroft: he did
05:10 PM roycroft: one of the best and most prescient farewell speeches ever made by a us president
05:10 PM CaptHindsight[m]: the same group that consistently make $$ no matter what
05:10 PM roycroft: and you know what
05:11 PM CaptHindsight[m]: liberal swings, conservative swings, war in (enter any place) ....
05:11 PM roycroft: those people were paying a marginal tax rate of over 90% during the eisenhower administration, and they were still filthy rich
05:11 PM CaptHindsight[m]: we just don't care yet
05:11 PM coralgoat: I have had trouble with graphics cards and wifi receivers for Linux in the past. Do I need to make sure to buy a Linux compatible parallel port?
05:11 PM roycroft: i'm on vacation again in 5 minute
05:11 PM roycroft: s
05:11 PM roycroft: that's what i care about now :)
05:12 PM roycroft: you are probably not going to like what i'm about to say ,coralgoat
05:12 PM CaptHindsight[m]: coralgoat: it depends..
05:12 PM roycroft: but if i were you, for linuxcnc i'd buy mesa 5125 + whatever daughterboard you need
05:12 PM CaptHindsight[m]: coralgoat: what will you be connecting to the LPT port? Just a BOB or a Mesa FPGA?
05:12 PM roycroft: 5i25, rather
05:13 PM roycroft: and offload the motion control handling to the mesa board
05:13 PM coralgoat: Information about the CNC router I am trying to get working is logged here starting at 09:59 AM:
05:13 PM roycroft: if the full line of mesa boards were available i'd recommend an ethernet based one, as that would be less expensive
05:13 PM coralgoat: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/2022-03-29.html
05:13 PM CaptHindsight[m]: coralgoat: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH I have been using these for either
05:13 PM roycroft: but the 5i25 is still in stock, as are some of the daughter boards for it
05:14 PM coralgoat: So a problem with the machine is that the 3 axies controller is not set up to control spindle speed which is done manually by another box.
05:15 PM roycroft: if you're driving stepper motors, this is what i would recommend today:
05:15 PM roycroft: https://mesaus.com/product/5i25-7i76-kit/
05:15 PM CaptHindsight[m]: https://www.china-cncrouter.com/products/Mach3-USB-CNC-6040-3-Axis-4-Axis-Mini-CNC-Router-with-1500W-2200W-Spindle-Sink-Cooling-System-and-Z.html
05:15 PM CaptHindsight[m]: you need to drop that controller
05:15 PM roycroft: ack, those look out of stock today :(
05:15 PM roycroft: they were just in stock recently
05:16 PM * roycroft is so happy he has the mesa boards he needs for his mill and router
05:16 PM CaptHindsight[m]: coralgoat: I read some of the backlog, have you realized that you need to drop that controller and replace with a PC?
05:17 PM CaptHindsight[m]: coralgoat: the hardware that you can keep is everything from the mechanics to the motors
05:17 PM roycroft: i don't now what to recommend now
05:18 PM roycroft: but i am on vacation again now, so i am happy
05:18 PM JT-Shop: the only stock I have is 7i80HD-25 plus daughter cards
05:18 PM CaptHindsight[m]: https://www.china-cncrouter.com/upfile/images/11/20170508174711770.jpg is his LPT card inside the "controller"
05:18 PM JT-Shop: and maybe a 5i25 and 6i25
05:19 PM CaptHindsight[m]: unterhaus_: had a link to the discussion on the forums for the "controller" he is using
05:20 PM CaptHindsight[m]: roycroft: his stepper drives can handle Step and Dir from an LPT port
05:20 PM CaptHindsight[m]: ^^^ pic posted above
05:21 PM CaptHindsight[m]: coralgoat: so where are you at on how this works with LCNC?
05:21 PM roycroft: the answer to the question about a parallel port is that they are pretty generic, and very cheap
05:21 PM roycroft: a $14 random parallel port card will probably work fine with linux
05:21 PM CaptHindsight[m]: how may we un-confuse you?
05:22 PM coralgoat: CaptHindsight[m], Can you elaborate on "have you realized that you need to drop that controller and replace with a PC" please.
05:22 PM roycroft: pcw is not the reason that i'm pissed off about the supply side problems and lack of us manufacturing of computer chips
05:22 PM coralgoat: I have a x86 desktop with Linuxcnc installed on it and it meets the Linuxcnc specs.
05:22 PM roycroft: i've been pissed off about that for a very long time
05:22 PM roycroft: but he is definitely the poster child for why it's such a critical issue now
05:23 PM CaptHindsight[m]: coralgoat: sure, I realized after I posted that you had asked this before and we found links to the insides
05:23 PM CaptHindsight[m]: so you can keep your "controller"
05:23 PM CaptHindsight[m]: we just need to get you working with a PCI/e - LPT card and proper config and hal files
05:24 PM CaptHindsight[m]: we don't know if your Step and Dir are active low or high for the inputs to that board
05:25 PM CaptHindsight[m]: roycroft: he is working on a new FPGA board design using Chinese sourced FPGA's
05:25 PM CaptHindsight[m]: not ideal, but at least he can get large quantities of FPGA's for now
05:26 PM CaptHindsight[m]: coralgoat: your "controller" is BOB (breakout board) with integrated stepper motor drives
05:27 PM roycroft: yeah, i know he is
05:27 PM JT-Shop: I think one of my #5 bench planes is at type 11 from 1910-1918
05:27 PM roycroft: but that perpetuates the same problem
05:27 PM JT-Shop: or someone changed the cap...
05:27 PM roycroft: nice
05:27 PM CaptHindsight[m]: so you can follow most of the forums and wiki info on setting up a mill using stepper motors with a LPT port
05:27 PM roycroft: my compass plane and scraper plane date from around then
05:28 PM JT-Shop: that plane was a friends fathers or grandfathers plane so the date fits
05:29 PM * roycroft just received two parcels - one from lie-nielsen and one from auber instruments
05:29 PM * JT-Shop likes auber instruments
05:29 PM roycroft: i buy all my pid controllers from them
05:29 PM roycroft: which is one of the items i got today
05:30 PM coralgoat: roycroft, is this the mesa 5i25 you mentioned? http://store.mesanet.com/index.php?route=product/product&product_id=55
05:30 PM roycroft: and since this kiln is used for heat treating metals, amongst other things, i got the fancy one that does ramp/soak cycles
05:30 PM JT-Shop: nice
05:30 PM coralgoat: roycroft, how should I determine the daughterboard needed?
05:31 PM roycroft: you determine what you need to control with it, and then you ask jt-shop
05:31 PM roycroft: :)
05:31 PM JT-Shop: daughter boards for DB-25 cards are mostly out of stock
05:31 PM JT-Shop: you need a PCI slot for a 5i25...
05:32 PM CaptHindsight[m]: coralgoat: https://www.youtube.com/watch?v=T11zmexLyPc he has covered this in a multipart video
05:33 PM roycroft: i have a 5i25/7i76 for my mill
05:33 PM coralgoat: roycroft, can you point out a model number for an ethernet mesa board?
05:33 PM CaptHindsight[m]: IF coralgoat: follows your advice he will have to get new stepper drives or have you help him wire the Mesa Stepper card to his driver board
05:33 PM CaptHindsight[m]: so good luck
05:34 PM roycroft: i have a 7i96 for my router
05:34 PM roycroft: and if they were in stock anywhere i'd recommend that
05:34 PM roycroft: well he can't follow my advice
05:34 PM roycroft: because almost all mesa products are currently made of unobtanium
05:34 PM CaptHindsight[m]: which stepper drives do you recommend for him?
05:34 PM coralgoat: CaptHindsight[m], I will watch that multipart video.
05:34 PM JT-Shop: yep no stock on 7i96
05:35 PM roycroft: you were out of stock when i ordered mine
05:35 PM JT-Shop: when the 7i96S is finished then we will have stock on that card
05:35 PM roycroft: and then you found one a couple days later
05:35 PM CaptHindsight[m]: OR he could just get an LPT card
05:35 PM roycroft: i've already answered his lpt question
05:36 PM JT-Shop: 7i92's are in stock as well as 7i80HD-25
05:36 PM CaptHindsight[m]: who is going to help him wire it all up?
05:37 PM roycroft: i would also advise ditching the current drivers and replacing them with gecko drives
05:37 PM roycroft: because gecko drives are hard to blow up :)
05:37 PM coralgoat: CaptHindsight[m], thank you for this link http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH I will shop for that card.
05:37 PM CaptHindsight[m]: heh OK
05:37 PM CaptHindsight[m]: OR he could just a turn key mill
05:37 PM CaptHindsight[m]: * could just buy a turn
05:37 PM roycroft: yeah, but where's the fun in that?
05:37 PM JT-Shop: roycroft, I found some walnut handles for the #5 I'm working on
05:38 PM CaptHindsight[m]: WTF is going on?
05:38 PM CaptHindsight[m]: are you just kidding?
05:38 PM unterhaus_: the 7i80hd will plug right to a parport bob
05:38 PM roycroft: nice
05:38 PM JT-Shop: $30 delivered
05:39 PM unterhaus_: or whatever you want to call that parport stepper driver thing
05:39 PM roycroft: although it would be more fun to make your own tote
05:39 PM roycroft: so i have a 55 degree frog for my no. 4 now
05:39 PM coralgoat: roycroft, yes I am driving stepper motors.
05:39 PM roycroft: this is perfect
05:39 PM JT-Shop: what's that for?
05:39 PM unterhaus_: is your #4 a stanley?
05:39 PM roycroft: no, it's a lie-nielsen
05:39 PM roycroft: the bronze model
05:40 PM unterhaus_: okay, I wondered where you got the frog
05:40 PM roycroft: i got it from lie-nielsen
05:40 PM roycroft: it came with a 45 degree frog
05:40 PM unterhaus_: I knew they had that
05:40 PM unterhaus_: just not rich enough for one
05:40 PM roycroft: the norris-style plane i am planning on finishing making some day has a 50 degree bed
05:41 PM roycroft: so with this frog i get all three common bed angles on a smoother
05:41 PM CaptHindsight[m]: coralgoat: look over how the connections from an LPT port to a BOB work with Stepconf
05:41 PM CaptHindsight[m]: and the halfile
05:41 PM CaptHindsight[m]: hal file
05:41 PM unterhaus_: it would be nice if the thread about that stepper board had more details
05:41 PM roycroft: plus i have a stanley 112 scraper plane with a thick blade from ron hock for the extremely gnarly stuff
05:42 PM CaptHindsight[m]: if that is confusing, you need to see how this works before you start spending more money
05:42 PM CaptHindsight[m]: unterhaus_: yeah it kind of left things hanging
05:42 PM unterhaus_: Andy says you can reassign the pins on that board somehow
05:42 PM JT-Shop: I really like the ron hock blades I got
05:42 PM CaptHindsight[m]: what is missing from that thread is inputs and outputs other than the Step and Dir
05:42 PM roycroft: they are great
05:43 PM roycroft: what kind of steel did you get?
05:43 PM unterhaus_: I ended up getting a Leevalley for my #7
05:43 PM roycroft: i need to get an 01 blade from him for my no. 4
05:43 PM unterhaus_: the splitter was screwed up on it
05:43 PM roycroft: it came with cryo treated a2
05:43 PM roycroft: if you need plane blades, unterhaus_, go to hockblades.com
05:44 PM roycroft: he's in mendocino - fort bragg
05:44 PM CaptHindsight[m]: coralgoat: you need to understand this thread https://forum.linuxcnc.org/49-basic-configuration/35628-basic-configuration-for-a-chinese-6040-cnc-router-please?start=0
05:44 PM roycroft: just a stone's throw away from the college of the redwoods
05:44 PM roycroft: he started making plane blades for james krenov back in the '80s
05:44 PM roycroft: and turned that into a full time business
05:45 PM CaptHindsight[m]: coralgoat: the router uses the same "controller" as yours
05:46 PM JT-Shop: looks like lie-nielsen only has 4 and 4 1/2 smoothing planes in stock and no brass ones
05:46 PM roycroft: they take backorders
05:47 PM roycroft: and for backorders are usually only a couple weeks out
05:47 PM JT-Shop: nice
05:47 PM roycroft: some of their stuff has a waiting list
05:47 PM roycroft: you sign up and they email you when it's in stock
05:47 PM JT-Shop: only a couple have backorders
05:47 PM roycroft: i'm kind of bummed, because i just ordered the frog that way
05:47 PM JT-Shop: Please Note: Due to foundry issues, the No. 4 Bronze Smoothing Plane is temporarily unavailable for backorder. We are working to resolve these issues and will have them available as soon as we can. Thank you for your patience.
05:48 PM roycroft: and the frog adjustment screwdriver has also been on waiting list hold
05:48 PM roycroft: today i got the email that the screwdriver is back in stock
05:48 PM roycroft: so i had to place a separate order for that
05:48 PM roycroft: but at least they are getting stock regularly
05:49 PM Tom_L: and you are removing it regularly :)
05:49 PM roycroft: yes, too regularly :(
05:49 PM roycroft: my weekly dinner engagement is tonight this week, instead of the usual wednesday
05:49 PM JT-Shop: I found myself in walmart today and the isles were full of stock waiting to be put on the shelves
05:49 PM roycroft: but i think i have time to hook up the pid controller and see if the temperature probe works properly before i go
05:50 PM Tom_L: shelves are still pretty sparce here
05:50 PM roycroft: my list at lie-nielsen is getting small, tom_l
05:50 PM roycroft: as is my wallet
05:50 PM Tom_L: oh no!
05:50 PM roycroft: funny how that works
05:50 PM CaptHindsight[m]: coralgoat: maybe https://www.amazon.com/GODSHARK-Parallel-Expansion-Converter-Controller/dp/B07R3XTZMN/ref=zg_bs_3015423011_3/131-5235217-9335230
05:51 PM JT-Shop: I did use the strop on ron's blades but that's all and cut shavings so thin you could see through them
05:52 PM roycroft: i think that a skew block plane is the only major tool left on my list
05:52 PM roycroft: did you get o1 or a2, jt-shop?
05:52 PM coralgoat: I am going away from the computer for a little bit. Then I will come back and read the backlog of helpful comments I have received about my questions. Thanks
05:52 PM Tom_L: so after getting down to depth thru the middle i tried stepping over with a .375 em to see how it would do
05:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture24.jpg
05:52 PM * roycroft guesses o1, given the wafa-thin shavings
05:52 PM Tom_L: i think i'll be doing more of that as needed
05:53 PM JT-Shop: O1
05:53 PM roycroft: the extra thickness of his blades helps a lot
05:53 PM roycroft: no chatter
05:53 PM Tom_L: .020-.030 slices
05:53 PM roycroft: and o1 is much finer grained than a2
05:53 PM Tom_L: i think it was quicker than taking shallow cuts and certainly better finish
05:54 PM JT-Shop: better finish on the side walls?
05:54 PM Tom_L: yes
05:54 PM Tom_L: .6" depth
05:56 PM Tom_L: didn't really get a good pic of the sidewall
05:56 PM Tom_L: for bending the tabs on those parts
05:56 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture21.jpg
05:57 PM JT-Shop: is that 6061T6?
05:57 PM Tom_L: yes that or T651
05:57 PM JT-Shop: bends well
05:57 PM Tom_L: oh the part is annealed
05:58 PM Tom_L: the fixture is hardened
05:58 PM Tom_L: they break if you try bending t material
05:58 PM Tom_L: i did a few and wound up annealing the tab end
05:59 PM JT-Shop: I thought so, how did you anneal it?
05:59 PM Tom_L: propane torch
06:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture17.jpg
06:00 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture18.jpg
06:01 PM JT-Shop: nice
06:01 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_New/MODS/fixture/A9_Fixture21.jpg
06:01 PM Tom_L: no stress cracks
06:02 PM Tom_L: less force to bend it than i'd expected
06:21 PM * coralgoat reading backlog.
06:37 PM coralgoat: JT-Shop, you said "the only stock I have is 7i80HD-25 plus daughter cards". Can you share a link for your 7i80HD-25?
06:38 PM coralgoat: JT-Shop, you also said "maybe a 5i25 and 6i25". Do you have links for those?
06:42 PM coralgoat: CaptHindsight[m], you said "LTP port" what does LTP stand for?
06:48 PM coralgoat: CaptHindsight[m], you said "so you can follow most of the forums and wiki info on setting up a mill using stepper motors with a LPT port". I have been trying to follow the documentation http://linuxcnc.org/docs/stable/html/config/stepconf.html can you share a link for a good forum or wiki article on this?
06:49 PM roycroft: well the temperature display on the pid controller matches up very closely with the analog temperature display on the kiln - within less than 10 degrees
06:49 PM roycroft: the pid controller reads a little higher, but the pid controller thermocouple is closer to the heating element, so that may account for the difference
06:50 PM CaptHindsight[m]: coralgoat: LTP is a typo of LPT, same for PTL :)
06:50 PM roycroft: of course i have no way of knowing if either is accurate
06:50 PM roycroft: but in the end, it doesn't matter if the temperature reading is accurate - only that it's consistent
06:53 PM CaptHindsight[m]: coralgoat: https://www.youtube.com/watch?v=_QhrtteG1M4
07:05 PM coralgoat: CaptHindsight[m], looked at https://acronyms.thefreedictionary.com/PTL it is not obvious from that what PTL is. Could you spell out the acronym?
07:05 PM t4nk_freenode: Partial Translation Level
07:06 PM coralgoat: t4nk_freenode, thanks
07:08 PM coralgoat: CaptHindsight[m], Thanks for the video link.
07:08 PM coralgoat: I have previously tried to get the x, y and z axis to jog. They did not. I think the problem was the USB parallel port adapter I was testing with.
07:08 PM t4nk_freenode: yeah, there don't seem to be any drivers for linux for it
07:09 PM t4nk_freenode: so it won't register to the kernel properly
07:09 PM t4nk_freenode: and it won't work
07:09 PM CaptHindsight[m]: coralgoat: https://forum.linuxcnc.org/49-basic-configuration/29023-stepconf-setup
07:09 PM CaptHindsight[m]: coralgoat: a whole forum on it https://forum.linuxcnc.org/16-stepconf-wizard
07:13 PM coralgoat: CaptHindsight[m], thanks for those links. I will take some time to read through them. I will also explore the forum which I have not done yet.
07:13 PM CaptHindsight[m]: coralgoat: too many threads to count on LPT setups
07:15 PM CaptHindsight[m]: coralgoat: once you have a LPT card you can play with stepconf, get comfortable with it and then ask for help with wiring
07:15 PM roycroft: i need some enameling tool, so i went to the super-expensive jeweler's supply websites to find what i needed
07:15 PM CaptHindsight[m]: coralgoat: have you found a suitable PC yet with low enough latency?
07:16 PM roycroft: then decided to go check on ebay and amazon for the same items at better prices
07:16 PM roycroft: but on ebay and amazon they are 2x as much and more than on the super expensive jeweler's supply sites
07:16 PM CaptHindsight[m]: coralgoat: http://linuxcnc.org/docs/html/install/latency-test.html
07:18 PM coralgoat: CaptHindsight[m], the x86 desktop computer with Linuxcnc installed on it meets the system requirements. http://linuxcnc.org/docs/stable/html/getting-started/system-requirements.html
07:20 PM CaptHindsight[m]: coralgoat: some PC's don't play with realtime since they have broken BIOS's
07:20 PM CaptHindsight[m]: * don't play well with realtime
07:23 PM coralgoat: CaptHindsight[m], I will take a note of the max jitter is below 100,000 nanoseconds http://linuxcnc.org/docs/stable/html/config/stepconf.html#_latency_test next time I am in the shop.
07:24 PM coralgoat: CaptHindsight[m], would it be safe to say that the BIOS is okay if the max jitter is below the 100,000 nanoseconds?
07:26 PM CaptHindsight[m]: coralgoat: it depends on how fast you want the machine to move
07:27 PM CaptHindsight[m]: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test
07:28 PM CaptHindsight[m]: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration
07:31 PM coralgoat: Is max jitter sufficient to diagnose a BIOS that has a problem with real time?
07:33 PM CaptHindsight[m]: max jitter tested under the proper conditions, long enough and under stress
07:34 PM CaptHindsight[m]: sometimes it can take 30 minutes to an hour for some SMI event to occur to mess with the timings
07:34 PM CaptHindsight[m]: giant threads on this as well https://forum.linuxcnc.org/18-computer/39371-results-of-latency-test-list-of-computers-tested-for-use-with-linuxcnc
07:36 PM CaptHindsight[m]: coralgoat: IF you wish to spend more $$ and use a poor performing PC you can use Mesa FPGA cards IF they are in stock
07:36 PM CaptHindsight[m]: LPT software stepping only works well with some PC's, those with low latency jitter
07:37 PM CaptHindsight[m]: and that if often up to IF the BIOS lets you kill power management, speed stepping/cpu clock throttling etc etc
07:37 PM CaptHindsight[m]: and kills all out of band operations
07:38 PM CaptHindsight[m]: why most laptops and servers can't be used for software stepping
07:41 PM coralgoat: Will any male parallel to male parallel cable work or are there also important consideration for the cable used?
07:42 PM Tom_L: 25pin thru shielded
07:42 PM Tom_L: not all db25 are created equal
07:42 PM Tom_L: some only bring out certain signals
07:43 PM CaptHindsight[m]: IEEE1284 compliant cables will get you the longest distance between LPT card and your "controller"
07:45 PM CaptHindsight[m]: the good ones look about twice as thick as the corner cutters
08:01 PM coralgoat: Here is a cable I found https://www.amazon.com/dp/B08FCN2BRH/ it says it is IEEE1284.
08:03 PM CaptHindsight[m]: coralgoat: no idea, no reviews
08:05 PM CaptHindsight[m]: coralgoat: https://mesaus.com/product/db25m-db25m/
08:06 PM CaptHindsight[m]: http://store.mesanet.com/index.php?route=product/product&path=74_81&product_id=273
08:07 PM CaptHindsight[m]: coralgoat: I have a few that I picked up from Microcenter that were clearly labeled as IEEE1284 compliant
08:12 PM coralgoat: CaptHindsight[m], for https://mesaus.com/product/db25m-db25m/ I am assuming from the picture that because both sides have the thumb screws to fasten the connectors that both ends are male.
08:13 PM coralgoat: Also maybe the M in DB25M stands for male.
08:14 PM CaptHindsight[m]: M stands for male
08:15 PM CaptHindsight[m]: you have to double check what YOU need on each end for your "controller" and the LPT card
08:15 PM CaptHindsight[m]: i forget what is shown in the picture of your "controller"
08:15 PM coralgoat: The controller is female.
08:16 PM coralgoat: The LPT card will likely be female as well.
08:18 PM CaptHindsight[m]: so likely a cable with male at each end
08:19 PM CaptHindsight[m]: i have a small pile of gender changers left
08:19 PM CaptHindsight[m]: all this is getting more difficult to source
08:20 PM CaptHindsight[m]: be sure to avoid any cable with a centronics connector
08:21 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/IEEE_1284#/media/File:IEEE_1284_printer_cable,_type_AB-0135.jpg
08:29 PM CaptHindsight[m]: when I type L, P or T in any order, e.g., PTL, LTP, PLT etc etc i likely mean LPT when discussing parallel ports :)
08:31 PM t4nk_freenode: that's because all LPT ports are basically Partially Transmissable Long-distance and Livery-Transmissable-Pipes anyhow
08:32 PM CaptHindsight[m]: same same
