05:39 AM JT-Cave: morning
05:47 AM XXCoder: quite dry for cold day here
05:47 AM XXCoder: my room is at 29% humidity lol
05:48 AM JT-Cave: we are usually pretty humid in the morning and drying out in the afternoon but looks like rain here off and on for the next few days
05:49 AM XXCoder: ironic youre getting more rain than here, which is supposely rain forest biome.
05:49 AM JT-Cave: 14 minutes until dawn and Queen Victoria is wandering around and looking in the nest box
06:24 AM JT-Cave: err 1h 14m
06:24 AM XXCoder: :)
06:34 AM Tom_L: morning
06:36 AM XXCoder: hey
06:49 AM Tom_L: 38F hi 41
06:50 AM XXCoder: 39f, max 48f
06:52 AM JT-Cave: a tad warmer here 48°F high 55°F
06:53 AM Tom_L: chance of snow thru Tues
06:53 AM JT-Cave: keep that crap to yourself lol
06:54 AM XXCoder: send some to me please
06:54 AM Tom_L: i doubt we get any
06:54 AM XXCoder: here combination is very low humidity
06:54 AM XXCoder: but maybe rain after a week
06:57 AM Tom_L: you're in Washington?
06:57 AM Tom_L: i thought it rained all the time ther
06:57 AM XXCoder: its SUPPOSED TO
06:58 AM XXCoder: its been getting worse and worse. drier and drier
06:58 AM XXCoder: we now have 5 seasons here now
07:01 AM XXCoder: im shivering a little lol
07:01 AM XXCoder: my ac is heatong my room, but rest of house isnt heated yet
07:01 AM XXCoder: so my door is spraying cold air to me lol
07:01 AM XXCoder: annoying
07:02 AM JT-Cave: stuff a towel under the door
07:04 AM XXCoder: i suppose but meh lol
07:04 AM XXCoder: its doing nicely on drying my room though lol
07:05 AM XXCoder: my room was at 50% 2 weeks now
07:05 AM XXCoder: ago
07:40 AM jymmmm: Morning, Oh goody, another 3 day blackout starting this afternoon
07:42 AM XXCoder: ugh does it get cold there
07:42 AM XXCoder: and why do you constantly get blackouts?
07:48 AM jymmmm: XXCoder: Yes, it's cold here today, I just pulled out the propane heater. During fire season, when there is predicted high winds, they do a blackout. It's to prevent another wildfire, because they were found at fault in 2018 which killed 98 people and burned 150,000 acres
07:48 AM XXCoder: ouch. time to upgrade power system :(
07:48 AM XXCoder: if its that often i would add solar and alternate power sources if can afford
07:48 AM XXCoder: even if its like 1kw it would make difference if it goes direct to heat
07:49 AM jymmmm: XXCoder: Solar won't work for where I am, 50ft trees and snow in the forest.
07:49 AM XXCoder: hows wind? theres a spot where it blows steady?
07:49 AM XXCoder: or mostly anyway
07:50 AM jymmmm: There's usually ZERO wind, not even a slight breeze most of the time.
07:50 AM XXCoder: hmm drat
07:52 AM jymmmm: Everyone will be at the gas station today filling up their gas cans. I did my wash yesterday just in case it gets extended to a 5 day blackout
07:52 AM XXCoder: your water needs power tpo pump and such?
07:53 AM jymmmm: No, but the dryer is 220VAC
07:53 AM XXCoder: ahh yea clothes wash
07:53 AM XXCoder: can always hung up barely dirty clothes air out will be fine
07:54 AM jymmmm: Hey, I've already turned the clothes inside out to get extra usage ;)
07:54 AM XXCoder: lol
08:39 AM JT-Cave: wow I have 5.7GB of unused data for the month
08:39 AM XXCoder: download everything! ;)
08:39 AM XXCoder: or laternatively: dont download it at one place! ;)
08:43 AM JT-Cave: I found two 1/4-20 square nuts that I need to make a board puller with, one edge of the poop table side boards has warped out a bit and leaks a bit of Sweet PDZ on the floor
08:45 AM jymmmm: JT Hey, that's a full ISO/movie download =)
08:46 AM * JavaBean uses an unlimited data plan, even tho its 4/5g
08:47 AM jymmmm: Don't know if anyone cares, but found a 12/24V 8/4A charger/maintainer that doesn't look half bad, already ordered it... https://www.amazon.com/gp/product/B08G446ZQ9
08:47 AM jymmmm: JavaBean: But JT is on satellite, not celluar
08:48 AM JavaBean: satellite???? /me shudders, points out how expense overages would be
08:49 AM jymmmm: JavaBean: He knows it very well sadly
08:49 AM JT-Cave: no expense overages with Viasat, they just throttle you down only huges net does that crap
08:49 AM * JT-Cave smells bacon so it must be break fast time
08:49 AM JavaBean: hmm, will need to ping a friend of mine and find out why he isn't with viasat
08:49 AM jymmmm: Mmmmmmmmm BACON
08:51 AM jymmmm: BLAC Sandwich... Bacon, Lettuce, Avocado, Cheese on lightly toasted sourdough... YUM
08:51 AM JavaBean: ew, avocado...sourdough..... ew
08:52 AM jymmmm: Good, more for me!!!
08:53 AM jymmmm: Could drop the lettuce and add a fried egg instead too =)
08:54 AM JavaBean: nothing wrong with a breakfast sammich... but no avocado/sour dough, that shit is nasty
08:56 AM jymmmm: JT This is really good surprisingly, they sell at dollartree for $1 too... https://www.amazon.com/Badia-Complete-Seasoning-12-OZ/dp/B003T07WNG/
09:05 AM XXCoder: whats taste type is it
09:05 AM XXCoder: sour bitter or what
09:06 AM XXCoder: .2 .3 and 12 pack
09:06 AM XXCoder: think i prefer 12 pack. better deal ;)
09:09 AM * JavaBean grumbles, wants to just enjoy this day... decent freeze scheduled for monday night and fairly decent freeze scheduled for tuesday night... in the desert southwest, where it is forecast to be 5-10f above normal today(79f)
09:33 AM JT-Cave: JavaBean, also your friend might want to know that Viasat has a 10GB plan with unmetered between 4AM and 8AM which when I download videos and stuff
10:23 AM JavaBean is now known as SquirrelMan5k
10:24 AM unterhaus_: trying to decide if I should hang my computer off of the cabinet door. Cables might make it a problem
10:26 AM SquirrelMan5k is now known as JavaBean
10:51 AM Tom_L: unterhaus_, why not? http://tom-itx.no-ip.biz:81/~webpage/rue/Control1.jpg
10:51 AM Tom_L: how often do you plan to be inside it?
10:52 AM Tom_L: my cabinet was a little smaller than i'd prefer so i made it work
10:53 AM Tom_L: now though, most of that will be coming off
10:55 AM unterhaus_: Tom_L, maybe it would be better to put electronics on the door like you did
10:55 AM unterhaus_: I guess I could also put a panel in front of the computer inside the cabinet
10:56 AM unterhaus_: cabinet is at least 10" deep, computer is 4" deep
10:57 AM unterhaus_: Might still have to hang my vfd off the back of the cabinet
10:57 AM Tom_L: most of the electronics on the door is for the sherline motor control which is coming off as soon as i get my vfd
10:57 AM Tom_L: i'll put the vfd outside mine
10:59 AM Tom_L: arg. the electric co is now gonna start charging a $3 fee if you tie into the grid with any private generation
11:00 AM unterhaus_: since the only thing connecting the computer to the cabinet is an ethernet cable, I suppose I could put the computer on the back of the mill
11:00 AM Tom_L: keep it away from chips and coolant
11:00 AM unterhaus_: 3$ a month?
11:00 AM Tom_L: yup
11:00 AM unterhaus_: that's less than a lot of elec companies though
11:01 AM unterhaus_: how much do you generate?
11:02 AM Tom_L: i don't
11:02 AM Tom_L: but that doesn't encourage me to either
11:03 AM Tom_L: that's per kw
11:20 AM unterhaus_: okay, that's ridiculous
11:23 AM Tom_L: it's going before the energy commission
11:25 AM unterhaus_: they do have to put in a separate meter, which should be their problem
11:26 AM Tom_L: the alternate is to charge $35 minimum per customer but would apply to those that fall under that ammount
11:39 AM roycroft: so i was planning on operating my spindle manually at first when i do the cnc conversion of my mill
11:39 AM roycroft: but that's going to cause some complications with the estop circuitry
11:39 AM roycroft: i might need to add an extra contactor or something
11:40 AM roycroft: i don't think it's wise to have an estop button for the spindle and a different one motion control
11:40 AM unterhaus_: can't you interrupt the start/stop circuit?
11:41 AM Tom_L: roycroft, wire estop thru a dpdt relay and split it where needed
11:41 AM roycroft: i wonder if i should try to control the spindle with linuxcnc from the start
11:41 AM unterhaus_: I decided I'm going to have a relay for every switch and one set of relay contacts is going to be a daisy chained estop
11:42 AM roycroft: i think folks have done that
11:42 AM Tom_L: that's alot of relays to debug when they fail
11:42 AM roycroft: if i'm honest, i'm not even sure if my spindle motor is 3 phase ac or dc
11:42 AM roycroft: if it's ac i can just slap a different vfd on it and be done with it
11:43 AM roycroft: if it's dc i have other things to figure out
11:43 AM unterhaus_: Tom_L, I'll have to draw it out to see if that's a problem. I do have a lot of relays
11:46 AM roycroft: and the motor is neither
11:46 AM roycroft: it's a 120vac universal motor
11:49 AM Tom_L: no speed control on it?
11:49 AM roycroft: yes, it's variable speed
11:49 AM roycroft: which is why i thought it was 3 phase or dc
11:51 AM unterhaus_: universal is variable speed
11:51 AM unterhaus_: very much like a dc motor
11:51 AM unterhaus_: has brushes
11:52 AM unterhaus_: universal means ac or dc
11:52 AM unterhaus_: is there an explanation of what the mesa config file names mean?
11:53 AM Tom_L: peter has a method to the madness yes
11:53 AM Tom_L: what do you wanna know?
11:53 AM roycroft: the machine has a 3/4hp motor currently
11:53 AM unterhaus_: I have a 4 servo card and an io card
11:53 AM roycroft: i wonder if it's worth upgrading to 1hp
11:53 AM Tom_L: unterhaus_, alternatively you could look at the source file and see what they are
11:53 AM roycroft: i don't think i'd want to go bigger than that on that machine
11:54 AM Tom_L: roycroft, mine is going from ~200w to 1200
11:54 AM Tom_L: go for it
11:54 AM roycroft: 1hp motors cost about the same a 3/4hp
11:54 AM roycroft: it would be really easy to mount a new motor on the machine
11:55 AM unterhaus_: 1hp motors from china have a tariff for some reason
11:55 AM unterhaus_: brushless
11:55 AM unterhaus_: I think I would keep the current motor until it caused problems. Or go brushless
11:56 AM roycroft: spindle control with linuxcnc might be an issue
11:56 AM roycroft: that's why i'm pondering replacing it now
11:56 AM Tom_L: you can do + - 10v, 0-10v or modbus
11:56 AM Tom_L: or pwm
11:57 AM * roycroft peruses the linuxcnc forums
11:57 AM Tom_L: modbus you gotta worry about having or making a driver for your control
11:57 AM unterhaus_: looking at the source is a pita
11:57 AM Tom_L: not really
11:58 AM Tom_L: i'm not sure what file he loads for a default but if you plug it in and interrogate it with mesaflash you will know what you have also
11:59 AM {HD}: If you were choosing between starrett or mitutoyo which would you pick? I narrowed it down to either https://www.amazon.com/Mitutoyo-505-742-Caliper-Range-Accuracy/dp/B0142HWYIW or https://www.amazon.com/Starrett-3202-6-Hardened-Stainless-Graduation/dp/B00SJADL3G
12:00 PM Tom_L: {HD}, mitutoyo
12:00 PM Tom_L: with starret you are paying extra for the name
12:01 PM unterhaus_: starrett doesn't take tools like that seriously, I'm afraid
12:02 PM {HD}: Thats too bad. Is that a recent development? I thought starrett was top notch. Has it gone the way of snap-on?
12:02 PM Tom_L: either way, they're only as accurate as the last time you dropped it
12:02 PM Tom_L: {HD}, who hasn't?
12:03 PM Tom_L: it's a throw away world now, haven't ya heard?
12:03 PM {HD}: Tom_L: Well, I guess that is a good point. I like to think that there is still some quality stuff out there...somewhere. AvE just reviewed some tools that looked pretty nice. Probably way out of my $ range though.
12:03 PM roycroft: i don't know how you get mitutoyo tools repaired, but with starrett you just send them to massachusettes and they will repair them
12:03 PM roycroft: i had a 6" dial caliper that i dropped a while back and starrett fixed it for $60
12:03 PM roycroft: it took a couple weeks
12:04 PM roycroft: that was the first and, so far, only time i've ever dropped a dial caliper
12:04 PM {HD}: roycroft: I guess thats part of the problem. Repair is $60 when new is $90 and no wait...
12:04 PM roycroft: $30 buys me a couple nice bottles of mead
12:04 PM {HD}: Then you sell your 'like new' starrett dial calipers on ebay for $40.
12:04 PM roycroft: which i can enjoy while i'm waiting for my caliper to be repaired
12:04 PM {HD}: Yea, you just made 10$
12:05 PM roycroft: it wasn't a $90 caliper though
12:05 PM Tom_L: roycroft, as popular as mitutoyo is, i'm sure if you wanted to they have a US repair shop
12:05 PM roycroft: it was a $150 caliper
12:05 PM roycroft: they probably do, tom_l
12:05 PM roycroft: i just don't know
12:05 PM XXCoder: roy ya paid 70 to fix my caliper also
12:06 PM XXCoder: its half price of new one so yeah
12:06 PM Tom_L: https://www.mitutoyo.com/support/repair-service/
12:06 PM Tom_L: bingo
12:06 PM roycroft: some of the low end starrett tools are made overseas now, i believe
12:06 PM roycroft: but most of their stuff is still made in massechusettes
12:07 PM Tom_L: Arizona and California
12:07 PM roycroft: if that's important to you
12:08 PM Tom_L: have you seen how lazy americans are getting?
12:08 PM Tom_L: cutting corners etc...
12:08 PM {HD}: Well, the linked starrett dial calipers are not USA...by the looks of it.
12:08 PM Tom_L: i personally would flip a coin
12:08 PM roycroft: i don't know that americans are getting lazy
12:08 PM roycroft: american corporations are getting greedier
12:08 PM unterhaus_: I found out about Starrett 20 years ago
12:09 PM unterhaus_: I imagine a caliper from them would work okay unless it didn't
12:10 PM unterhaus_: unlike some other manufacturers where they all stink
12:10 PM unterhaus_: so the hostmot2 docs give some file name examples
12:12 PM unterhaus_: not updated to talk about ethernet cards though
12:13 PM unterhaus_: It's not laziness per se. Tough to make something in the U.S. and compete with China on stuff like a caliper
12:13 PM {HD}: are you saying you can drop digital calipers with less worry than dial calipers?
12:13 PM unterhaus_: also tough to move production overseas and maintain quality
12:14 PM unterhaus_: I suggest not dropping them, but that's just me
12:14 PM roycroft: if the cost of shipping was not externalized it would be more cost competitive to make things here than float them in from asia
12:15 PM unterhaus_: on mesa firmware, the actual pinout is configurable, right? So it's daughter card agnostic to that extent
12:15 PM Tom_L: unterhaus_, yes
12:16 PM Tom_L: just requires a different bit file
12:16 PM Tom_L: i did a custom one for mine
12:16 PM unterhaus_: maybe I'll use pncconf on my 5i20 and transfer the result to my ehternet setup
12:17 PM unterhaus_: the bit files come with the firmware zip?
12:18 PM unterhaus_: Pinxx.vhd?
12:18 PM Tom_L: there are some for each card
12:18 PM Tom_L: the most common ones
12:19 PM Tom_L: unterhaus_, what card do you have?
12:20 PM unterhaus_: I have a 7i93 want to drive 7i33/7i37
12:21 PM unterhaus_: I suspect I can get the bitfile from another card?
12:22 PM unterhaus_: no mention of the 7i37 in the source
12:22 PM Tom_L: isn't it a gpio card?
12:22 PM Tom_L: just a protection card?
12:22 PM unterhaus_: yes
12:22 PM Tom_L: doesn't need anything special then
12:22 PM Tom_L: if it's not a function like pwm encoder etc it's gpio
12:23 PM unterhaus_: doesn't it still need to know what pins to drive?
12:23 PM unterhaus_: some are input and some are output
12:23 PM Tom_L: no matter
12:24 PM Tom_L: you do that when you asign the pin
12:24 PM unterhaus_: I thought I allocated pwm and encoder in the main firmware and then connected them up somehow
12:25 PM Tom_L: how many io does the 7i93 have?
12:25 PM Tom_L: 48?
12:26 PM unterhaus_: ya
12:28 PM Tom_L: servos or steppers?
12:28 PM unterhaus_: servos
12:30 PM roycroft: the murder hornet nest that was found in northwest weashington has been removed
12:35 PM Tom_L: unterhaus_, the pin_SV8_48 has 8 pwm, 4 per plug
12:35 PM Tom_L: if you don't use the function, they can be used for GPIO
12:36 PM Tom_L: just randomly chose that one to look at...
12:36 PM Tom_L: the rest are encoder
12:38 PM Tom_L: you just need to make sure the pwm align with the daughter card inputs which they probably do
12:41 PM unterhaus_: I think I'll use pncconf with my 5i20 and see what it does
12:50 PM Tom_L: pncconf doesn't change the bitfile
12:51 PM unterhaus_: it makes a config that you can run, doesn't it?
12:51 PM Tom_L: it makes the software configs i believe
12:51 PM Tom_L: you still need the right bitfile loaded in the firmware
12:52 PM Tom_L: you're more than likely ok
12:52 PM Tom_L: but i'd run mesaflash and make sure
12:52 PM unterhaus_: okay
12:53 PM Tom_L: i've never used pncconf
12:53 PM unterhaus_: it is all I have ever done, never made a config by hand
12:54 PM Tom_L: but it's a tool to generate your .ini and .hal files
12:54 PM unterhaus_: still fuzzy about how this works
12:54 PM Tom_L: it doesn't cover every scenario
12:54 PM Tom_L: we will edumicate you
12:55 PM Tom_L: the bitfile configures the fpga for your setup
12:55 PM Tom_L: the ini and hal tie it to linuxcnc
01:01 PM unterhaus_: I recall having no problems with the 5i20, but I don't have a computer big enough that I want to use on the mill
01:26 PM unterhaus_: has hm2_eth been merged into hostmot2 or do the docs just ignore it?
01:28 PM unterhaus_: I only found it from a google search, but it's not mentioned in the 2.8 docs
01:51 PM unterhaus_: Tom_L, do you use a Mesa ethernet card?
01:53 PM unterhaus_: 2.8 pdf manual link on linuxcnc.org is pretty useless
01:53 PM unterhaus_: basically have to d/l every file to see if it's the one you want
01:56 PM Tom_L: unterhaus_, i have a couple i test with
01:56 PM Tom_L: what do you need?
01:56 PM unterhaus_: so I need to use HM2_eth driver?
01:56 PM Tom_L: yes along with the hm2 one
01:56 PM JT-Shop: that's for 7i96, 7i92, 7i95 etc
01:57 PM JT-Shop: AFAIK
01:57 PM JT-Shop: crap someone broke the html man pages for 2.8
01:57 PM unterhaus_: yeah, that's why I ask
01:58 PM JT-Shop: http://linuxcnc.org/docs/2.8/html/man/man9/hm2_eth.9.html
01:58 PM Tom_L: loadrt hostmot2
01:58 PM Tom_L: and
01:58 PM Tom_L: loadrt hm2_eth
01:58 PM JT-Shop: I mean I had the man pages in nice columns and now someone has broken that :(
01:58 PM Tom_L: more work
01:58 PM unterhaus_: there does not seem to be instructions in one place
01:59 PM Tom_L: and i use the alternate IP of 10.10.10.10 on my test card
01:59 PM JT-Shop: what are you using the hm2_eth on?
01:59 PM Tom_L: 7i93 for his
01:59 PM Tom_L: i have a 7i80 and a 7i92? iirc
02:00 PM JT-Shop: should be the same as the rest of the ethernet cards
02:00 PM Tom_L: yeah
02:01 PM Tom_L: you need both drivers
02:01 PM JT-Shop: I see he is replacing the 5i20 with the 7i93?
02:01 PM unterhaus_: there is no instructions for the other ethenent cards either
02:01 PM Tom_L: JT-Shop, i think so yes or making a different mill
02:01 PM Tom_L: unterhaus_, setting up the card should be in the card manual
02:02 PM unterhaus_: but maybe it's just the one driver step that is missing
02:02 PM JT-Shop: which step is missing?
02:02 PM Tom_L: iirc the ip defaults to 192.168.1.121
02:02 PM unterhaus_: the drivers
02:02 PM JT-Shop: from which manual
02:02 PM JT-Shop: yea they are all shipped jumpered for 192.168
02:02 PM JT-Shop: .1.121
02:02 PM unterhaus_: I mean the hm2-eth is not in the linuxcnc doc top level page
02:03 PM unterhaus_: how do you change the ip?
02:03 PM JT-Shop: jumpers, it's in the manual
02:03 PM Tom_L: with mesaflash
02:03 PM JT-Shop: the mesa manual
02:03 PM JT-Shop: no, jumpers
02:03 PM Tom_L: and jumper the board for the alternate ip
02:03 PM unterhaus_: it's one of the jumpers?
02:03 PM JT-Shop: or yes if you don'e like 10.10.10.10
02:04 PM JT-Shop: two jumpers set the ip address selection, three combinations
02:04 PM Tom_L: it has a default ip _and_ a user defineable one
02:04 PM unterhaus_: it's programmed as 10101010 but not mentioned in the manual
02:04 PM JT-Shop: there are three
02:04 PM Tom_L: the jumper selects between them
02:04 PM JT-Shop: I don't think any mesa or pico cards are in the linuxcnc manual
02:04 PM Tom_L: i'm not sure they should be actually
02:05 PM unterhaus_: it's also not mentioned in the mesa manual that the alternate is 10101010
02:05 PM Tom_L: yes
02:05 PM Tom_L: that's jumper selectable
02:05 PM unterhaus_: okay, not for the 93
02:05 PM JT-Shop: some are but the 93 just says fixed from eeprom
02:06 PM Tom_L: eeprom is erasable so i'm betting you can change it like i described
02:06 PM JT-Shop: exactly, the cards ship with 10.10.10.10
02:06 PM Tom_L: no need to though
02:06 PM JT-Shop: if you have more than one ethernet card you will
02:06 PM Tom_L: just set your pc up with a 10.10.10.xx address range
02:07 PM Tom_L: the card needs to be powered and connected for that
02:09 PM unterhaus_: so in my lcnc configs, I just have hm2_eth and not hostmot2?
02:09 PM unterhaus_: this is the question that is not answered anywhere that I have found
02:11 PM JT-Shop: https://paste.ubuntu.com/p/VQST7m8XNP/
02:12 PM JT-Shop: test.hal ^^
02:12 PM JT-Shop: https://paste.ubuntu.com/p/h3YQyMCmPp/
02:12 PM JT-Shop: that should load, can't test it right this second got some chicken repairs to do
02:13 PM Tom_L: unterhaus_, you need both
02:13 PM Tom_L: i load hostmot2 before hm2_eth
02:14 PM Tom_L: the 2nd one is line 17 of JT-Shop's sample config
02:15 PM Tom_L: the [BOARD] etc is set in the other file it calls
02:15 PM Tom_L: line 10
02:16 PM unterhaus_: okay, thanks
02:16 PM Tom_L: there are other parameters but that's the basics
02:24 PM * JT-Shop thinks he just smoked his 7i93... Note: On Rev. A boards, P5 polarity is the opposite of most Mesa 5V connectors so do not swap connectors from other Mesa cards.
02:25 PM JT-Shop: oh well I've never sold one anyway
02:28 PM unterhaus_: yeah, I just saw that in the manual
02:28 PM unterhaus_: have to make sure about that if I ever find my other one
02:29 PM unterhaus_: do I need a crossover cable to direct connect to a pc?
02:29 PM JT-Shop: I have one amber led lit by the nic connector, do you have more?
02:29 PM JT-Shop: no just a normal ethernet cable
02:31 PM unterhaus_: cool, thanks.
02:32 PM unterhaus_: I have to go to the basement and hook up the 5v power supply I just got, so no led at this moment
02:32 PM unterhaus_: reading the mesa manual again rn
02:43 PM Tom_L: JT-Shop, did he fix that on later boards?
02:51 PM pcw_home: There are no later than Rev A cards at least so far
02:57 PM unterhaus_: pcw_home how sensitive is the board to the 5v input level?
02:58 PM unterhaus_: didn't see a max/min rating
02:58 PM unterhaus_: nvm, didn't look hard enough
02:58 PM pcw_home: 5V +- 5% is standard
02:59 PM pcw_home: it will run at lower but the I/O levels will be funky
02:59 PM pcw_home: more than ~7V will cause damage
03:00 PM unterhaus_: I'm a bit annoyed my new power supply is adjustable
03:10 PM JT-Shop: pcw_home, if I connected power up bassakwards is my board toast?
03:13 PM pcw_home: Depends on the power supply current limit
03:15 PM pcw_home: there's a reverse protection diode, which may overheat/short out with > 10 A
03:19 PM JT-Shop: I use a USB plug power
03:20 PM pcw_home: that should not hurt anything
03:20 PM JT-Shop: CR8 got hot I think
03:21 PM pcw_home: yeah that's the reverse protection diode
03:21 PM JT-Shop: CR7 is amber and CR5 and CR6 flash red when powering up
03:21 PM pcw_home: thats correct
03:24 PM JT-Shop: hmm, angry ip only sees my 10.10.10.11 nic
03:29 PM pcw_home: Link light?
04:01 PM skunkworks: backup furnace for the shop... http://electronicsam.com/images/greenmachine/IMG_20201025_114834.jpg

04:06 PM * JT-Shop shop heater https://gnipsel.com/images/wood-heat/LogWood04.jpg
04:07 PM * JT-Shop notices Sam has the same bandsaw as him... wondering if you converted from a horz to a vert?
04:07 PM JT-Shop: garage heater https://gnipsel.com/images/wood-heat/chinlee-logwood-small.jpg
04:12 PM Deejay: gn8
04:13 PM Centreline: I have one of these mounted in a windowframe, takes up less space in my compact shop https://www.auto-parkingheater.com/uploads/201712645/diesel-car-parking-heater-2kw-12v-24v-diesel49578214598.jpg
04:15 PM Centreline: I have a big wood furnace and slab has underfloor pipework, but I couldnt fit the edm in AND have a furnace...
04:25 PM JT-Shop: never seen one like that
04:25 PM skunkworks: JT-Shop: bandsaw>?
04:26 PM skunkworks: Oh - That was a recent (last 5 years) purchase
04:26 PM Tom_L: missing a table
04:26 PM skunkworks: we use it both cut off and vertical.
04:27 PM skunkworks: there is a tin table that gets mounted with 2 scres. Works in a pinch
04:27 PM skunkworks: (we have 2 other large vertical bandsaws that get used more for vertical)
04:27 PM Tom_L: i'd settle for one
04:32 PM skunkworks: they heat with wood and never had a backup...
04:32 PM Centreline: JT-Shop, theyre made for RV's and motorhomes, run on diesel but expel exhaust gas outside so they don't gas the occupants but 4kw is enough for my machine area
04:33 PM skunkworks: that is a nice cutoff band saw with coolant...
04:34 PM Centreline: I was going to ask what the haynes was for, but its possible to read when zoomed in, ford superduty :)
04:34 PM skunkworks: we have a small 4X6? bandsaw that we have fixed many times since the the mid 80's
04:35 PM skunkworks: still use it.

04:41 PM Centreline: struggled with a converted ryobi vertical band saw, then got this http://gallery.pipandphil.com/Vehicles/workshop/in_workshop.jpg
04:42 PM Centreline: even my wife loves it after buying a frozen turkey too big to fit in our fridge/freezer, and I bandsawed a lump off still frozen one year
04:45 PM JT-Shop: nice a big doall
04:49 PM Centreline: the power feed is ingenious, just a big weight that pulls a cable you connect the stock, and a lever to stand on to lift the weight to stop pulling
04:55 PM JT-Shop: yea I've used them in the past, they can really cut up some metal quick
04:55 PM JT-Shop: does the blade welder still work?
05:03 PM -!- #linuxcnc mode set to +v by ChanServ
05:04 PM unterhaus_: I need a cutoff saw, but as usual no place to put it
05:04 PM Centreline: it does, but I confess I havent used it. I just run the same blade on everything and change the speed to suit
05:08 PM Centreline: and if I need a internal shape cutting out, I find a different way
05:10 PM Centreline: right cleanup is done,I have the encoder mounted on the interact spindle and it back together but I dont have enough shielded cable to run the cabling, so I think thats me out for the night, gnite all

07:07 PM unterhaus_: JT-Shop2, did you see how the html docs on the web page have been messed up?
08:23 PM veegee: ok I cannot find a hot water pressure washer for anything less than $5,000. absolutely ridiculous
08:24 PM veegee: I think I'm going to feed warm water (25-30ºC) to my cold water pressure washer and figure out a way to heat the water after the pump
08:25 PM roycroft: or don't make oily messes? :)
08:25 PM veegee: doesn't need to be 95ºC hot, just needs to be hot enough, like maybe 70ºC. Flow rate is 15L/min
08:25 PM _unreal_: veegee I dont see why you cant feed hot water from ahot water tank to your pressure washer
08:25 PM veegee: _unreal_ damages the pump
08:25 PM _unreal_: its water
08:25 PM veegee: the heat
08:25 PM veegee: they rely on cold water to keep cool
08:26 PM veegee: and at those pressures (4,200 PSI), the tolerances must be pretty tight
08:26 PM _unreal_: its connected to flame thrower (motor)
08:26 PM JavaBean: take a page from earlier opensource 3d printing... have a heater after the pump
08:26 PM roycroft: does anyone have a favorite vendor for contactors with 24vdc coils?
08:26 PM veegee: It's pretty well known not to feed hot water to cold water pressure washers. Some even mention a temperature limit in the manual
08:26 PM _unreal_: veegee, the idea of heating water after its run though a high pressure side is silly
08:27 PM _unreal_: your ADDING pressure
08:27 PM veegee: not much
08:27 PM veegee: I'm not creating steam
08:27 PM veegee: it's just "warming" the water
08:27 PM * roycroft would still be looking at a steam cleaner for an application like this
08:27 PM veegee: well I already dealt with the oil
08:27 PM roycroft: steam cleaners are fairly cheap
08:27 PM veegee: this is just for other stuff. hot water cleans waaaayyyy better than cold water
08:27 PM _unreal_: as I recall most pressure washers are rated for water temps upto 50c
08:27 PM JavaBean: pretty sure it was just kanthal wire wrapped around a non-conductive pipe
08:28 PM veegee: Unlike most savage people, I don't use toilet paper. I use water to clean myself after a "number 2" lol
08:28 PM veegee: like a civilized human
08:28 PM veegee: And warm water is far more effective than cold water. Just an example
08:29 PM _unreal_: veegee, https://www.hotsyab.com/blog/hot-vs-cold-water-pressure-washers/#:~:text=One%20can%20run%20warm%20water,pump%2C%20and%20overheat%20the%20unit.
08:29 PM veegee: so I have my bidet thing hooked up to a warm water source instead of the cold water line only
08:29 PM _unreal_: oh 65c
08:30 PM _unreal_: or 150F
08:30 PM veegee: Just the other day, I was made aware of the concept of "dingleberries". I cannot understand how most people live like that
08:30 PM veegee: just saying
08:30 PM _unreal_: O,O
08:30 PM _unreal_: :S
08:31 PM veegee: Well apparently it's a thing
08:31 PM veegee: now I get why people were hoarding toilet paper...
08:31 PM roycroft: i don't understand how men can walk around wearing tighty whities, but millions do
08:31 PM roycroft: so i guess it's just another case of different strokes for different folks
08:32 PM _unreal_: I use to be a boxer shorts guy
08:32 PM _unreal_: then I switched to boxer briefs
08:32 PM veegee: yeah same
08:32 PM _unreal_: never looked back
08:32 PM veegee: well I use both
08:32 PM _unreal_: tighty whities, GOOD LORD give me cirulation
08:33 PM roycroft: the correct undergarment is boxers with trousers
08:33 PM roycroft: and we just don't talk about undergarments with a kilt
08:33 PM roycroft: that is a mystery that must remain such
08:35 PM roycroft: -5 tonight
08:35 PM _unreal_: I'll never forget, I was wearing boxers. and back in my teens. I was doing something and jumped off of something high. when I landed I was fine but strained my balls do to lack of support.
08:35 PM roycroft: we're definitely going to have our first hard freeze of the season
08:35 PM _unreal_: tried then tighty whities and found to much support so I opted for a happy medium
08:35 PM _unreal_: :)
08:36 PM roycroft: i disconnected the hoses today and blew out the irrigation system
08:36 PM roycroft: so i'm prepared for winter in that respect
08:36 PM _unreal_: heh winter here is ahhh
08:36 PM _unreal_: make sure I still got gas to mow the lawn
08:36 PM _unreal_: LOL
08:36 PM roycroft: i have to cut the grass again
08:37 PM _unreal_: I believe the coldest day last year was like 45F for a day
08:37 PM roycroft: i was mending a fence today in addition to dealing with the irrigation system
08:37 PM _unreal_: and jumped right back to 70 ish
08:37 PM roycroft: i also went for a hike in the late afternoon
08:37 PM roycroft: cutting the grass did not happen
08:37 PM roycroft: i ran out of time
08:37 PM _unreal_: hicks down here are kind of dull
08:37 PM _unreal_: nikes
08:37 PM _unreal_: hikes
08:38 PM _unreal_: when I can afford it I'm going to take my daughter to DRY tortuga
08:38 PM roycroft: the city of eugene is at the very southern end of the willamette river valley
08:38 PM roycroft: the southern part of the city is bounded by a series of hills and buttes
08:38 PM _unreal_: https://www.drytortugas.com/
08:38 PM roycroft: and the city has been purchasing land there and have created a ridgeline trail that's really nice
08:39 PM roycroft: a segment of it was opened last year that has a trailhead less than 10 minutes from my house
08:39 PM roycroft: i hiked that segment of the trail for the first time today
08:39 PM roycroft: it's a really nice trail
08:39 PM _unreal_: GOD I cant wiat to take my daughter there
08:39 PM roycroft: and there were some nice views when i got to the summit
08:40 PM XXCoder: the correct undergarment is one youre confortable with
08:40 PM roycroft: tighty whitey people are uncomfortable all the time
08:40 PM roycroft: i suppose they find comfort in wearing undergarments that reinforce their discomfort
08:42 PM XXCoder: thats interesting overgeneralizion
08:42 PM XXCoder: i suppose you bought em once and regretted it
08:44 PM roycroft: i should hope you would recognise when i'm joking by now
08:45 PM roycroft: in case you don't, the above was joking
08:45 PM veegee: Now for a change of topic: these LiFePO4 cells are genuine grade A cells for a very reasonable price: https://www.aliexpress.com/item/4000306076197.html?spm=2114.12010612.8148356.1.7b795c92o50LCb
08:45 PM XXCoder: ah ok lol
08:45 PM veegee: Unless you're in Canada, in which case shipping is $200
08:45 PM JavaBean: oh, how did i not notice you were here... roycroft.... you stole my luck yesterday, neither place i stopped today had what i went to town to shop for
08:45 PM veegee: But they have a USA warehouse so shipping is next to nothing if you're lucky
08:46 PM XXCoder: vee is it for solar and such?
08:46 PM roycroft: yeah, but that's CAD$200
08:46 PM XXCoder: or night charge day discarge battery thinbg
08:46 PM veegee: Converting my forklift to hybrid
08:46 PM roycroft: which is like $4.95 in real money
08:46 PM veegee: so I can run it indoors, at least the hydraulics
08:46 PM XXCoder: ohh nice
08:47 PM veegee: I already have all the parts. Just need the batteries
08:47 PM veegee: So I guess I'm going to get T-105 lead acid batteries from the local supplier purely for cost reasons
08:48 PM veegee: I use the forklift like every day, but only for short periods. Internal combustion engines hate that kind of use where they never get to warm up
08:49 PM veegee: so much yellow gunk in the crankcase because the water never gets a chance to boil off. Alternative is to add a oil and coolant heater to warm up the system to operating temperature before turning it on
08:50 PM XXCoder: can replace with say natural has electricity generator and use electric engine for movements also?
08:50 PM XXCoder: is it even possible?
08:51 PM veegee: yes very
08:51 PM veegee: but whole point is to get rid of the internal combustion engine
08:51 PM XXCoder: yeah though with natural generator it would produce far less gas
08:52 PM veegee: it's propane powered so not bad as it is
08:52 PM XXCoder: unless your uses is short enough that you could just charge between uses
08:52 PM veegee: but engine wear is very high when the engine is cold
08:52 PM veegee: my uses are multiple times for very short periods, like < 10 minutes, per day
08:53 PM XXCoder: so pure electric powered would be best
08:54 PM veegee: Yeah
08:55 PM veegee: I would have bought a pure electric one, but they are far more expensive and rare for some reason
08:55 PM XXCoder: bit surpising if it can ve converted
08:55 PM XXCoder: but then people might be less willing to sell, so price is higher
08:56 PM veegee: of course it can. Just remove the entire engine block and drop in an electric motor like any conversion
08:56 PM XXCoder: cool :)
08:56 PM veegee: Well it's more involved than that, like mounting everything properly, but the electronics are simple
08:56 PM XXCoder: im not a big fan of industual polluting machines. (yes im an cnc machinist im weird)
08:56 PM veegee: CNC machines pollute?
08:57 PM veegee: Did you replace all the servos with honda GX25 engines?
08:58 PM XXCoder: sure it does
08:58 PM XXCoder: coolant for one
08:59 PM XXCoder: most of it is reclaimed and recyled but theres always some losses
08:59 PM veegee: I thought the coolant is constantly circulated and filtered
08:59 PM veegee: whatever it is, it must be far less polluting than owning a car
09:00 PM XXCoder: yeah im talking about industry in general, input and output from factory. it buys big tank and uses em in machines
09:00 PM XXCoder: most of it will be pumped and sent off
09:00 PM XXCoder: some spills, some mist floating away from machines
09:00 PM veegee: but if you do replace your servos with GX25 engines, that would be fun
09:00 PM XXCoder: lol
09:01 PM XXCoder: it'd have to be truly big machine to take advange of strength
09:01 PM roycroft: it's time for the 60 minutes interview with the president
09:02 PM veegee: Hmm now I'm searching for a < 25cc 4 stroke gasoline engine
09:03 PM veegee: So many cases where I could do with like 200W of power, but the smallest portable generators are at least 1kW
09:03 PM veegee: RC engines are cool, but not designed for longevity
09:06 PM veegee: https://www.trojanbattery.com/products/deep-cycle-flooded/signature-line-flooded-2/ pretty damn good cycle life for the T-105 golf cart batteries
09:07 PM veegee: $200 for each 6V 200Ah cell, very reasonable. 1,000 cycles at 60% DoD
11:13 PM unterhaus_: roycroft I usually check out the contactors at automation direct
11:13 PM unterhaus_: the U.S. brands are just shockingly expensive
11:14 PM unterhaus_: last time I needed one I looked at buying and then realized I had what I needed in the junk pile
11:14 PM unterhaus_: thought about going with Chinese through Amazon, probably okay
11:29 PM jesseg: veegee, have you checked out four stroke weed whackers? I don't know what country you're in, but in USA, they are selling some 4 stroke weed whackers. They are probably close to your <25cc criteria. They have a cute little notched rubber timing belt and about 3 tablespoons of crank case oil LOL..
11:29 PM jesseg: I don't know that they are any more fuel efficient than a regular 2-stroke weed whacker though :P
11:30 PM jesseg: For full speed operation, believe it or not, 2-stroke engines are awfully amazing with their low part count and firing on every cycle
11:31 PM jesseg: err every revolution :P
11:31 PM jesseg: I caught me before roycroft caught me :D
11:37 PM unterhaus_: 2 stroke are better in that application but 4 stroke is quieter and cleaner
11:37 PM unterhaus_: that's why 2 stroke has been going away
11:38 PM unterhaus_: but for weed whackers, I'm only using electric from now on
