12:32 AM skunkworks: another reason to have a 3d printer? http://electronicsam.com/images/greenmachine/IMG_20201228_002012.jpg
12:38 AM XXCoder: nice
12:38 AM XXCoder: yeah some lego parts is hjard to get
12:49 AM Eric__: that little cap on the stmbl is a lot harder to solder than I expected
12:50 AM Eric__: I admire the people who build them up from scratch
01:42 AM Deejay: moin
05:00 AM JT-Cave: morning
05:01 AM XXCoder: yo
05:42 AM fogl81: hello
05:43 AM fogl81: i wrote a simple g-code with conditions. If i compare two variables linuxcnc doesn't load the code
05:43 AM fogl81: if [#2 GT #3]
05:43 AM fogl81: is this not allowed, is there some workaround
05:44 AM JT-Cave: is there an error?
05:44 AM fogl81: no, it youst stops
05:45 AM fogl81: no, it just stops
05:45 AM fogl81: a loading bar stops in the middle and that is it
05:45 AM JT-Cave: sounds like you have an endless loop in the code
05:46 AM fogl81: yes it is
05:46 AM fogl81: is this also a problem
05:46 AM JT-Cave: what would you expect an endless loop to do?
05:46 AM fogl81: wait for some input and execute subroutine
05:46 AM fogl81: and wait again
05:47 AM JT-Cave: M66 is wait on input
05:48 AM fogl81: i have M66, it reads two input and compare them
05:49 AM fogl81: all this in endless loop
05:50 AM Tom_L: morning
05:51 AM JT-Cave: morning
05:52 AM JT-Cave: an endless loop will never finish loading if the preview is on
05:53 AM fogl81: ok, so the comparison is not the problem, i will limit the loop to some large number and see what i get
05:53 AM fogl81: thank you for your suggestion
05:53 AM JT-Cave: turn off the preview
05:55 AM JT-Cave: if your using Axis you can
05:56 AM fogl81: you mean View->Show program?
05:56 AM fogl81: This did not solve the problem
05:56 AM JT-Cave: (AXIS,stop) Stops the preview from here to the end of the file.
05:56 AM rs[m]: fogl81: you can check in your g-code if it is running to calculate preview or if it executing on machine
05:56 AM JT-Cave: if your using Axis
05:56 AM rs[m]: fogl81: and skip the loop for preview
05:57 AM JT-Cave: http://linuxcnc.org/docs/2.8/html/gui/axis.html#axis:preview-control
05:57 AM fogl81: Ok, i see :) Thank you, will try that
06:08 AM rs[m]: fogl81: check out #<_task>
06:09 AM rs[m]: #<_task> - 1.0 if the executing interpreter instance is part of milltask, 0.0 otherwise. Sometimes it is necessary to treat this case specially to retain proper preview, for instance when testing the success of a probe (G38.n) by inspecting #5070, which will always fail in the preview interpreter (e.g. Axis).
06:18 AM JT-Cave: I don't think my planer parts will arrive today like the usps says... they are still in St Louis
06:28 AM Tom_L: workin on the range parts today?
06:28 AM JT-Cave: going to drop off the jack shafts and test the stepper at 24v and if needed 48v
06:29 AM Tom_L: did you have rope on it for your local test?
06:29 AM JT-Cave: no
06:29 AM Tom_L: that might make a difference
06:29 AM Tom_L: with a target load
06:30 AM JT-Cave: that's why I'm testing today
06:30 AM Tom_L: is the target just paper or is there a backer board?
06:30 AM JT-Cave: just paper
06:34 AM Tom_L: i think i would put a 'home' switch up by the shooter in case lead gets in the way and the stepper misses steps on the way, that could be a good reset point without the worry of getting shot up
06:36 AM JT-Cave: I plan on homing each time it returns to the shooter, prob with a prox or a micro switch
06:36 AM Tom_L: good idea
07:51 AM JT-Cave: hmm odd terminal won't use wifi if an ethernet cable is plugged in but solved that by adding metric
09:38 AM tjtr33: CaptHindsight, hello. i been working on the OPi and I think I just found why it had problems loosing steps.
09:39 AM tjtr33: The arisc_stepgen totally ignores STepLen STepSpace DirHold and Dir whatever the preparatory one was called
09:39 AM tjtr33: They dont exists in the arisc_stepgen,c or .h
09:40 AM tjtr33: so, should i study the bad code or try to implement the std LinuxCNC stepgen in the arisc side of the OPi's brain?
09:46 AM CaptHindsight: tjtr33: hello
09:47 AM CaptHindsight: tjtr33: I have had little time to look into it
09:48 AM CaptHindsight: tjtr33: I wish I did
09:49 AM CaptHindsight: tjtr33: I would not be suprised that they ignored how it's already done since kids tend to want to reinvent the wheel
09:49 AM CaptHindsight: I don't think they ever asked
09:52 AM tjtr33: well the rulke for the timing are from the drive manufactureres, no linuxcnc. so its just wrong
09:52 AM tjtr33: rules
09:52 AM CaptHindsight: tjtr33: you are likely on to why it's nroken
09:53 AM CaptHindsight: nroken/broken
09:53 AM tjtr33: i know the PICnc simply set up a frequency and split ot into 50% duty cycle, creating a steplen and stepspace in an ugly way
09:54 AM tjtr33: ok, i will study how the original stepgen.c works
09:54 AM CaptHindsight: sounds maker-ishly like the *duino stuff I see
09:55 AM CaptHindsight: they don't ask, they don't know but they know it all, just ask em
09:55 AM tjtr33: the code has the look of MachineKit, how he makes arrays of pins and functions.
09:55 AM tjtr33: I think he did a lot, he also did a lot of hardware design, and was very much on his own.
09:56 AM CaptHindsight: yes, no reason for the isolation
09:57 AM tjtr33: well he left a lot on the web, like studies of the realtime latency using rt-tests with cyclictest
09:57 AM CaptHindsight: why we stopped working on the ARM stuff, no cooperation just parallel races to hack something out that almost works
09:58 AM CaptHindsight: it's just stupid
09:58 AM tjtr33: same applies for linuxcnc, why dont we use standard latency testsm why did we build our own when the rt people have tools for that
09:58 AM tjtr33: i suppose poeple begin wgere they can and go where they can get to
09:58 AM CaptHindsight: I don't know, seem to be the culture for a while
09:59 AM tjtr33: hokay well i hope the best for you and yours, happy new year
09:59 AM CaptHindsight: little cooperation with parallel projects
09:59 AM CaptHindsight: happy new year!
09:59 AM tjtr33: choke dee pee mai ( good luck new year )
10:00 AM CaptHindsight: sorry if I sound negative but I live in a really stupid country
10:00 AM tjtr33: well a bit of not bad news a couple hours ago, he signed the relief bill
10:01 AM CaptHindsight: folow the right examples, ask questions, I'm sure it will work
10:01 AM tjtr33: ok thx again . gnite
10:01 AM CaptHindsight: night
10:11 AM unterhaus_: I'm sure lcnc's latency tests are older
10:13 AM unterhaus_: probably come from rt-linux, RIP
10:14 AM Tom_L: naw it was written on stone tablets carved by cavemen!
10:14 AM Tom_L: good morning btw
10:15 AM unterhaus_: I was trying to remember if there was something before rt-linux and failed
10:15 AM Tom_L: go back and read the nist papers
10:16 AM unterhaus_: I think I will skip :)
10:16 AM Tom_L: https://www.nist.gov/publications/enhanced-machine-controller-emc-open-architecture-controller-machine-tools
10:16 AM CaptHindsight: nah should run on winders and use USB to send steps
10:16 AM Tom_L: CaptHindsight, any idea how he's progressing on the RTAI?
10:16 AM Tom_L: if at all...
10:17 AM CaptHindsight: yes, he hasn't touched it
10:17 AM Tom_L: fair enough
10:17 AM CaptHindsight: no time, no funding
10:18 AM CaptHindsight: and no cooperation from rati.org since you aren't supposed to fix rtai.org code without their blessing
10:18 AM * Tom_L offers a lucky penny
10:18 AM Tom_L: yeah so i hear
10:18 AM CaptHindsight: more drama
10:19 AM Tom_L: "it can't be wrong... i wrote it"
10:19 AM CaptHindsight: and I'll attack you for pointing out my errors or cleaning any code
10:20 AM Tom_L: such a baby
10:21 AM CaptHindsight: nah just people that are used to getting their way vs cooperating
10:22 AM Tom_L: only children?
10:22 AM CaptHindsight: very in now
10:22 AM Tom_L: or xgen
10:22 AM Tom_L: gen z?
10:22 AM Tom_L: can't keep up
10:23 AM CaptHindsight: early boomer actually
10:24 AM CaptHindsight: skilled at deflecting
10:24 AM Tom_L: gen z can't be taught
10:24 AM Tom_L: mostly
10:25 AM CaptHindsight: I see just the opposite, they are very well trained
10:25 AM Tom_L: not to be self sufficient
10:26 AM unterhaus_: I always thought it was weird that Paolo was doing most of the programming
10:26 AM CaptHindsight: tom will likely fix the arisc stepgen by just modifying what already work
10:26 AM unterhaus_: or are we talking about someone else
10:26 AM CaptHindsight: he is rtai.org
10:26 AM unterhaus_: "works on my computer" isn't much help
10:27 AM CaptHindsight: he paints the big strokes but ignores the fine details
10:27 AM CaptHindsight: xenomai has more devs
10:28 AM CaptHindsight: their roadmmap was to leave a dual kernel approach
10:29 AM CaptHindsight: and focus on preempt
10:29 AM CaptHindsight: bu they still update ipipe
10:30 AM CaptHindsight: Tom_L: heh, self sufficient cloud based everything :)
10:33 AM CaptHindsight: unterhaus_: Paolo not tom, to clarify
10:34 AM CaptHindsight: in recent discussions with maker types they get the impression that LCNC only runs on old kernels and machinekit-hal is the way to go
10:34 AM Tom_L: is machinekit regularly updated?
10:35 AM CaptHindsight: they also seem to be Linux experts that don't know that LCNC can run on the latest preempt_rt kernels
10:35 AM CaptHindsight: they seem to think that kernels are tied to a particular distro
10:36 AM roycroft: linux is just a kernel
10:36 AM CaptHindsight: Tom_L: machineket-hal is the new branch/fork
10:36 AM roycroft: everything else is part of the distro
10:36 AM roycroft: anyone who does not know this is hardly a linux expert imo :)
10:36 AM Tom_L: new?
10:36 AM CaptHindsight: roycroft: they don't seem to know that they can build kernels for Debian
10:37 AM Tom_L: i recall when the split was made but didn't know anything was 'recent' new
10:37 AM CaptHindsight: they seem to think that you can only use the kernels that debian posts to what is found in the package manager sources
10:38 AM CaptHindsight: roycroft: yes, was using the term expert sarcastically
10:39 AM CaptHindsight: Tom_L: https://github.com/machinekit/machinekit-hal
10:40 AM roycroft: so years ago i did some bitcoin mining, and i have almost 2 bitcoins in my wallet
10:40 AM roycroft: the passphrase to my wallet is printed on a piece of paper that i've been unable to find
10:40 AM CaptHindsight: was $20k per bc a week or so ago
10:40 AM roycroft: i think it's time to expend some concerted energy finding it
10:40 AM roycroft: it hit $28k over the weekend
10:41 AM CaptHindsight: there you go
10:41 AM roycroft: the last time i looked for that piece of paper it had just hit $10k
10:41 AM roycroft: and then dropped back down to about $600
10:41 AM roycroft: i lost interest in finding the paper
10:41 AM CaptHindsight: a windfall if you find them
10:41 AM roycroft: suddenly i find myself interested again :)
10:41 AM Tom_L: CaptHindsight, huh, what's new about it do you know?
10:41 AM CaptHindsight: sounds like sell time
10:42 AM Tom_L: not that i plan to switch
10:42 AM roycroft: it would also inspire me to finish scanning the last few boxes of unsorted paperwork
10:42 AM CaptHindsight: Tom_L: not sure but has some updates from the past few months
10:42 AM CaptHindsight: might just be cosmetic
10:42 AM roycroft: i've spent several years scanning and shredding from time to time, and have probably 90+% of all my papers scanned
10:42 AM roycroft: i only have a few boxes to go
10:43 AM roycroft: but ~$50k would be nice
10:43 AM CaptHindsight: should cover lunches for a while
10:43 AM roycroft: even after 15% capital gains tax
10:44 AM roycroft: which should be double that
10:45 AM CaptHindsight: back later, have a nice day
10:47 AM roycroft: if i found that piece of paper this year and sold half the bitcoin this year and half after the first of the year, my capital gains tax would be 0
10:48 AM roycroft: although i may be selling a domain name next year, which would drive it above the threshold
10:48 AM roycroft: but i could still sell $39,999 worth this year at 0%
11:00 AM unterhaus_: the guy that threw away his laptop that he used for mining must really be kicking himself now
11:00 AM unterhaus_: when I saw the story it was worth $7 million
11:00 AM unterhaus_: I think that might have been in the $1000 days
11:49 AM roycroft: i have a big jar of camphor tablets arriving today
11:49 AM roycroft: i already have a big bag of empty film cannisters - the plastic cannisters that 35mm film comes in (for those of you who remember film photography)
11:50 AM roycroft: i'm going to punch holes in the film cannisters, fill them with camphor, and stick one in each drawer of my machinsts and woodworking tool chests
11:50 AM roycroft: hopefully this will be effective in keeping tools from rusting
12:05 PM Tom_L: roycroft, iirc fugi had the clear ones which i liked better
12:06 PM Tom_L: fuji
12:08 PM roycroft: i have some clear ones
12:08 PM roycroft: but most are the common black with grey lid
12:08 PM Tom_L: kodak yes
12:08 PM roycroft: i have a few really old aluminium ones, including some wit a yellow lid
12:08 PM roycroft: with
12:09 PM Tom_L: i used to have some film cans from movie film
12:09 PM roycroft: but for the camphor tablets i don't think the material or color matters
12:09 PM roycroft: i still have some
12:09 PM roycroft: back in an early life i worked for a film company
12:09 PM Tom_L: 70mm? iirc
12:09 PM roycroft: the ones i have are 16mm and 35mm
12:10 PM Tom_L: maybe they were 35mm i don't remember now
12:10 PM roycroft: i've read good things about using camphor as a rust preventative
12:10 PM roycroft: 70mm is just 35mm with the image flipped 90 degrees
12:10 PM roycroft: so the cans would be the same size
12:10 PM Tom_L: they were from hollywood productions so probably 70mm
12:12 PM Tom_L: ok, out to try another part
01:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Jacobs_chuck/Chuck_adapter1.jpg
01:39 PM Tom_L: <Tom_L> http://tom-itx.no-ip.biz:81/~webpage/cnc/Jacobs_chuck/Chuck_adapter2.jpg
01:39 PM Tom_L: <Tom_L> http://tom-itx.no-ip.biz:81/~webpage/cnc/Jacobs_chuck/Chuck_adapter3.jpg
01:39 PM Tom_L: <Tom_L> https://www.youtube.com/watch?v=Y_WWPBGEfIA
02:05 PM beachbumpete1: What machine is that for Tom?
02:09 PM _unreal_: well thats flipping interesting
02:09 PM _unreal_: so looking at my christmas money $150.. whoo whooo. thinking about getting a laser cutter or 3d printer
02:09 PM _unreal_: the only thing on amazon in that range are 3d printers
02:09 PM _unreal_: amazon has just about nothing for laser etcher cutters
02:10 PM _unreal_: checking ebay
02:13 PM _unreal_: wow there are litteraly NO laser etchers on ebay
02:19 PM CaptHindsight: I was wrong about the Orange Pi LCNc dev, he did ask for help, but after he ran out of time vs when he was planning
02:21 PM beachbumpete1: Im getting ready to order a diode laser module for my 3D printer now that it is back together and working again
02:22 PM beachbumpete1: trying to decide on which one
02:22 PM beachbumpete1: kinda want a 20 or 30 watt unit
02:22 PM beachbumpete1: that is actually more like 7 apparently
02:23 PM beachbumpete1: open to recommendations ;)
02:25 PM Tom_L: beachbumpete1, fits my sherline spindle
02:26 PM beachbumpete1: Ah ok nice
02:29 PM roycroft: beachbumpete1: you asked me what laser i got for my printer
02:30 PM roycroft: this is what i got: https://www.ebay.com/itm//143138770486
02:30 PM roycroft: it says it's 4.5w, but the one i got is 6w
02:30 PM roycroft: it took less than a week to arrive
02:31 PM roycroft: if you get a bigger laser you're not going to be able to mount it in place of the print head - you'll need to mount it horizontally behind the printer and redirect the beam with mirrors
02:33 PM roycroft: i think the lasers like mine go up to 10w
02:36 PM roycroft: oh, i found a couple that are 15w
02:37 PM roycroft: https://www.ebay.com/itm/143401522272
02:44 PM _unreal_: I'm toying with this https://www.amazon.com/gp/product/B08HV57Y5M/ref=ox_sc_act_title_1?smid=A17AQSTQPGAVJO&psc=1
02:44 PM CaptHindsight: https://www.ebay.com/itm/30W-40W-CNC-Laser-Module-head-fits-Laser-engraver-cutting-machine-Cutter-printer/313314318234
02:44 PM _unreal_: have not made up my mind but I have yet to find anything better
02:44 PM CaptHindsight: input about 30W/40W ha ha
02:44 PM _unreal_: I have $150 christmas money I dont mind tossing in $50 on top
02:45 PM roycroft: i'm going to mount my laser on my ender 5 printer
02:45 PM CaptHindsight: if the Chinese use an even power efficiency power supply they could claim 100 or 200w for power :)
02:46 PM CaptHindsight: even lower efficiency
02:46 PM _unreal_: hum
02:46 PM _unreal_: nbot sure which machine to go with
02:47 PM CaptHindsight: roycroft: since they are messing with input vs output power you have to read the fine print
02:47 PM roycroft: yes, capthindsight
02:47 PM roycroft: and in my scan a few minutes ago i did not bother with that
02:48 PM roycroft: i know the one i bought was rated at 4.5w output, but what i received says 6w output
02:48 PM _unreal_: https://www.amazon.com/2500mW-Engraver-Marking-Machine-30x40cm/dp/B08KS3NWDH/ref=sr_1_289?crid=210FQX2VN2U4H&dchild=1&keywords=laser+engraver&qid=1609187232&sprefix=laser+etcher%2Caps%2C198&sr=8-289
02:48 PM _unreal_: that one is smaller though :S
02:48 PM _unreal_: and the same price
02:48 PM CaptHindsight: well the Chinese like to gamble
02:48 PM _unreal_: oh AND weaker laser
02:48 PM roycroft: i think they send whatever they have in stock that is at least the rated output or above
02:51 PM CaptHindsight: https://i.ebayimg.com/images/g/uJkAAOSwl~BcoTgv/s-l400.jpg handy
03:03 PM CaptHindsight: tjtr33 I wonder now if the only problem is that he hard coded the Step and Dir pulse widths vs allowing users to set them
03:04 PM CaptHindsight: and it misses steps due to the Step being to short a pulse
03:17 PM CaptHindsight: https://orangecnc.gitlab.io/arisc-driver.html I don't see any settings for pulse width
03:33 PM CaptHindsight: https://gitlab.com/orangecnc/arisc_cli/-/blob/master/arisc.c
03:35 PM CaptHindsight: https://gitlab.com/orangecnc/arisc_fw/-/blob/master/pulsgen.h
03:35 PM roycroft: well yay
03:36 PM roycroft: i have syncthing installed on my freenas server now
03:36 PM roycroft: it does not install properly from the plugin manager, but i was able to build an iocage jail manually and install it in that
03:37 PM roycroft: i had started using nextcloud for document sharing, but never did much with it in my personal network
03:37 PM roycroft: we use it at work and it's great for what we do, but it is a little clunky for a single user and way overkill
03:37 PM roycroft: i've been meaning to give syncthing a go for quite some time, and i'm glad it's finally happening
03:56 PM serp: I am personally a big nextcloud fan
03:57 PM roycroft: it's great at work
03:57 PM roycroft: but i already have a webdav, carddav, and caldav server on my home network
03:58 PM roycroft: and i don't need any features like email notifications etc.
03:58 PM roycroft: i just need synchnronized file sharing
03:58 PM roycroft: i want simple and robust, and syncthing appears to do that
03:58 PM serp: I have not tried it but heard people that like it
03:58 PM roycroft: plus, syncthing has a nice feature where it can keep local copies of deleted files for a configurable period of time
03:59 PM roycroft: that's nice if you accidently stomp on a file by making changes in multiple places
03:59 PM ve7it: why would any business trust offsite storage and managment of their data... how many businesses will die when nextcloud vaporizes?
03:59 PM roycroft: huh?
03:59 PM roycroft: nextcloud is self-hosted
03:59 PM roycroft: or can be
03:59 PM roycroft: we self-host :)
03:59 PM ve7it: better
04:00 PM serp: yes i definitely self host it
04:00 PM roycroft: we don't sell cloud storage services
04:00 PM Tom_L: off site i hope in case the building burns down
04:00 PM roycroft: syncthing is also self-hosted
04:00 PM roycroft: our nextcloud data are stored on a nas
04:01 PM roycroft: that nas replicates to another nas in the same data center in real time
04:01 PM roycroft: that replication nas backs up offsite every 15 minutes
04:01 PM roycroft: which is exactly how i have my nas at my home office set up
04:01 PM ve7it: nice
04:02 PM roycroft: for all the important stuff
04:02 PM roycroft: i also retain snapshots on my nas for 2 years
04:02 PM Tom_L: have you ever done a recovery from offsite to verify it's integrity?
04:02 PM roycroft: yes, i do that on a regular basis
04:02 PM roycroft: as in monthly
04:03 PM roycroft: my boss does not like my "wasting" my time verifying the integrity of the offsite backups
04:03 PM roycroft: but he appreciates it when i have to retrieve something from them
04:04 PM roycroft: he does not seem to get the connection between the two
04:24 PM _unreal_: so I think I'm going to settle on that larger laser etcher with the 3watt head
04:26 PM roycroft: what would you be etching?
04:26 PM * roycroft finds it odd that so many folks are interested in laser etching at the same time
04:27 PM XXCoder: probably so many not busy anymore
04:28 PM enleth: roycroft: the tech has gotten dirt cheap and readily available lately
04:28 PM roycroft: well there are three people on this channel, including myself, that i know of who are working on laser etching
04:28 PM roycroft: right now, i mean
04:28 PM _unreal_: COOL just got my THREAD MILL in the mail
04:29 PM enleth: I'm waiting for a 7/16" helicoil tap and some coils to arrive, to fix a boneheaded design mistake in my bridgeport
04:29 PM andypugh: I was more interested in: https://youtu.be/A3QaGqD9s-c especially when combined with https://youtu.be/LBiiDpexmA8
04:29 PM _unreal_: the threadmill head is smaller then I was expecting
04:30 PM _unreal_: but then again I've never fucked with them so we shall see
04:30 PM _unreal_: I'll prob do some tests tonight
04:30 PM _unreal_: TESTS in foam
04:31 PM _unreal_: well got to run to the store get some shit
04:31 PM _unreal_: and convert my gift cards to amazon cards
04:33 PM andypugh: Interesting threadmill tale: http://www.f1-2000.co.uk/index.php?f=conrods
04:33 PM andypugh: (search for the word “ordeal”
04:34 PM andypugh: Or, just to quote: A terrifying ordeal
04:34 PM andypugh: Much as one might try (and I did!), it is virtually impossible to cut a thread in Ti using a tap.
04:34 PM andypugh: This led to several problems with the M2X0.4 bolt threads in the rods. I don’t have a an M2X0.4 threadmill, there hasn’t been one on EBay in over 2 years, they cost about 130 quid new, the shank is so bloody thin it looks like it would break as soon as it touched anything and .... the FP2 won’t do helical interpolation in the Y axis / horizontal spindle. I had to bite the bullet and order a threadmill from Isa
04:34 PM andypugh: in the end. I then had to sit down and write a section in the post processor to take care if the helical interpolation in different tool planes. To see that tiny cutter disappearing up a 1.6mm hole for the first time was indeed a terrifying ordeal!
04:34 PM andypugh: But the pictures are cool.
04:36 PM enleth: if anyone among you ever happens to become a proud owner of a rigid ram Series 1 Bridgeport and decides to do a top end overhaul, make sure you have 7/16" helicoils at hand, to swap the direction of bolts holding the motor bracket casting to the ball screw spacer on top of the head - someone at BP screwed up big time and made those two components bolt together from underneath, with the bolt heads utterly
04:36 PM enleth: inaccessible until the whole assembly is off the machine
04:36 PM enleth: this makes it impossible to pull the spindle motor out of the machine easily and safely, among other things
04:37 PM enleth: it's trapped between the ram and the bracket, which can't be removed by itself in a stock machine
04:40 PM enleth: that's not the only design oversight on the rigid ram head, I guess they were in a hurry to get the drawings out to the foundry and never stopped to consider maintenance access to a whole bunch of subassemblies
04:42 PM enleth: the guys on the assembly floor tasked with bolting the quill to the ball screw in-situ must have hated the draftsman with a burning passion
04:43 PM enleth: unless they were 6-year-olds, in which case they might have had small enough hands to be able to reach comfortably into the casting cavity with the bolts and tools
05:05 PM Tom_L: andypugh, one that small, you might not even know you broke it
05:06 PM Tom_L: and yes, the first time was a bit butt puckering
05:07 PM andypugh: Tom_L: Well until you saw no thread and had another £130 ro find. And bear in mind that he had written the circular interpolation sub himself, and not in LinuxCNC.
05:07 PM Tom_L: what is that in inch? onlinecarbide has some tiny ones
05:07 PM JT-Shop: I appreciate PayPal sending me all those offers for business loans... it helps to keep my shop warm
05:08 PM Tom_L: http://onlinecarbide.com/07280tpi.html
05:09 PM Tom_L: .040 cutter diam
05:09 PM JT-Shop: I had a successful test at the range today with 24v drive power
05:09 PM Tom_L: cool
05:09 PM Tom_L: they happy so far?
05:09 PM roycroft: m2 is like 5/64"
05:10 PM Tom_L: that cutter should work then for alot less than he paid
05:10 PM JT-Shop: they are ecstatic to see it move
05:10 PM Tom_L: i bet
05:10 PM Tom_L: hook the rope up and do a live test?
05:10 PM JT-Shop: I think they have been struggling for quite some time
05:10 PM Tom_L: just talking to the wrong ppl
05:10 PM JT-Shop: yea moved the target back and forth and figured out the scale
05:11 PM JT-Shop: his wife came in said does it work and I pressed a button and it ran out to 10 yards and she high fived me
05:12 PM Tom_L: hah
05:12 PM JT-Shop: video in the morning
05:18 PM JT-Shop: https://gnipsel.com/images/customers/BobG/target-sys-02.jpg
05:19 PM _unreal_: OK got my stupid gift cards converted
05:19 PM _unreal_: to an amazon gift card
05:22 PM Tom_L: JT-Shop, looks good
05:23 PM Tom_L: i finally got a couple adapters made i can use
05:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Jacobs_chuck/Chuck_adapter4.jpg
05:24 PM XXCoder: JT-Shop: nice
05:24 PM _unreal_: Just ordered this
05:24 PM _unreal_: https://www.amazon.com/gp/product/B08HV57Y5M/ref=ox_sc_act_title_1?smid=A17AQSTQPGAVJO&psc=1
05:24 PM _unreal_: I could not find a better deal
05:26 PM XXCoder: tom looks very clean
05:27 PM andypugh: Late night YouTube. World Records. Most Jenga pieces removed in 1 minute. With a party blower. In the nose….
05:27 PM XXCoder: you sure its not just falling down ;)
05:27 PM Tom_L: that site i posted the other day is spot on for threading minor diameters
05:27 PM _unreal_: I wish it had a more powerful laser etcher head but its work area is like 15" LARGER in both x and y then everything else that is more expensive and same designs
05:28 PM roycroft: what are you going to be etching with it, _unreal_?
05:28 PM andypugh: Latest ebay bargain(?). https://www.ebay.co.uk/itm/173856186392
05:29 PM Tom_L: andypugh, most of those come off robotic arms don't they?
05:30 PM andypugh: Not those particular ones, I don’t think
05:30 PM _unreal_: roycroft, anything
05:30 PM _unreal_: etching/cutting
05:30 PM andypugh: They have a really cancy crossed-roller bearing.
05:30 PM Tom_L: cutting paper?
05:30 PM roycroft: that encompasses a vast array of things
05:31 PM _unreal_: A 100MW can cut paper
05:31 PM roycroft: my prediction is that you may have success cutting/etching some subset of "anything" and will utterly fail with the majority of "anything"
05:31 PM _unreal_: I'm sure that can do a little bit more
05:31 PM _unreal_: My main goal will be engraving
05:31 PM roycroft: not metals, i hope
05:32 PM andypugh: You will note the mis-reading of FHA-17C for FHA-170.
05:32 PM _unreal_: cutting boards. HDM
05:32 PM andypugh: Here is another, though admittedly working: https://www.ebay.co.uk/itm/233569925908
05:32 PM roycroft: you'll probably have some success with cutting boards
05:32 PM _unreal_: ldm what ever that crap sign material is called
05:32 PM _unreal_: my home etcher had no issues etching it
05:33 PM roycroft: with that small a laser, probably more "branding" than "engraving"
05:33 PM _unreal_: I plan on upgrading the laser head anyways
05:33 PM _unreal_: not right off the bat but sooner or later
05:34 PM roycroft: my expectation is that with the laser i bought i'll be able to successfully do some resist etching of non-ferrous metals
05:34 PM roycroft: i think i should be able to succeed at that, once i figure out what works well as a resist mask
05:34 PM JT-Cave: tom did all the ops from one side?
05:35 PM Tom_L: all but the bottom chamfer yes
05:35 PM Tom_L: op stop flip n go
05:35 PM JT-Cave: cool
05:35 PM _unreal_: do any of you guys have thread mills?
05:35 PM Tom_L: ~10 min spindle time
05:35 PM roycroft: i recall your saying you wanted to do that to ensure concentricity
05:35 PM _unreal_: seeing as how I got mine today in the mail
05:35 PM Tom_L: _unreal_, i have a set
05:35 PM _unreal_: any one other then tom
05:35 PM _unreal_: :)
05:37 PM JT-Cave: my planer parts tracking finally got updated and seems like they departed St Louis at 6:26 am...
05:37 PM Tom_L: _unreal_, http://www.carbidedepot.com/formulas-tap-standard.htm
05:37 PM Tom_L: those numbers are spot on for thread milling
05:38 PM _unreal_: ok
05:38 PM _unreal_: so now that I ordered my laser etcher. I'll be able to use that shell I built finally
05:39 PM _unreal_: https://photos.google.com/share/AF1QipNjUL9VJW4BIh58ZOHM6jOWS10l43lfzL_nr7FMD-YXm_o6hG63BfTN2Rv6ch6C_Q?key=OVV0UTBXUmF0NXNSR2NKVzdoaFhxQzVTbDI5V3JB
05:39 PM _unreal_: that bastard
05:40 PM XXCoder: jt finally taking a trip eh
05:40 PM _unreal_: if I have a better set I'm going to upgrade the motors right off the bat
05:40 PM _unreal_: ! I do likely have a better set of motors, they have built in encoders but I dont have any way of using them :S
05:41 PM _unreal_: hum
05:41 PM Tom_L: JT-Cave, you could hop on your bicycle and get them before they arrive
05:42 PM JT-Cave: a bit cold for a bicycle ride lol
05:43 PM XXCoder: just wear a coat ;)
05:44 PM JT-Cave: it is only 44°F outside but the low is 28°F... crap forgot to take the hose off the faucet
05:45 PM JT-Cave: I ordered a sure step smart drive and a hmi to test with...
05:45 PM roycroft: i did that in october, when i blew out my irrigation system and opened all the valves
05:46 PM roycroft: my irrigation pipes are barely below ground level, but our frost line is at ground level, so it's not a huge deal
05:46 PM JT-Cave: I clean all the poop tools daily so unless it's freezing all day I have a 10' hose connected
05:46 PM roycroft: there are some risers, though, that won't totally drain on their own
05:46 PM roycroft: aah, yeah
05:47 PM roycroft: you can't really winterize the water system if you're actively using it during the winter
05:47 PM JT-Cave: yeah
05:47 PM JT-Cave: if it's below freezing all day it's a bucket inside to clean them
05:48 PM roycroft: it looks like we will get down to -4 tonight
05:48 PM JT-Cave: ouch
05:48 PM roycroft: but it's 8 degrees out now, and will get up to 6 tomorrow
05:48 PM JT-Cave: but you use C right?
05:48 PM roycroft: yes
05:48 PM roycroft: so it's not that bad
05:49 PM roycroft: and it will get above freezing every day
05:49 PM roycroft: in the teens by week's end again
05:55 PM JT-Cave: wife took a personal day tomorrow lol her next to last day
05:57 PM XXCoder: reminds of lady my brother knew as coworker
05:57 PM XXCoder: she never had a day off or vacation for long time. decades
05:57 PM _unreal_: how many of you guys have laser etcher/cutters?
05:57 PM XXCoder: when she was ready to retire, she went on vacation for over a year
05:57 PM XXCoder: then she was "sick" for months
05:57 PM JT-Cave: wow
05:57 PM XXCoder: then she retired
05:58 PM XXCoder: yeah crazy
05:58 PM JT-Cave: she was just frustrated with her replacement not being organized lol
05:58 PM _unreal_: typical
05:58 PM XXCoder: your wife? lol well maybe new person will take up job well, or maybe noit
05:58 PM _unreal_: oh wait thats todays youth
05:59 PM JT-Cave: yea my wife
05:59 PM _unreal_: t4nk_freenode, your too quiet
06:01 PM t4nk_freenode: sorry, boss
06:03 PM t4nk_freenode: waaatchagonnadooo
06:04 PM _unreal_: t4nk_freenode, did you see the laser etcher I just ordered
06:04 PM t4nk_freenode: hell no?
06:05 PM _unreal_: scroll up and have a peek
06:05 PM t4nk_freenode: that's too much hassle!
06:05 PM _unreal_: ?
06:05 PM t4nk_freenode: all that reading and stuff
06:05 PM JT-Cave: and another one bites the dust and joins the ignore group
06:05 PM _unreal_: fine https://www.amazon.com/gp/product/B08HV57Y5M/ref=ox_sc_act_title_1?smid=A17AQSTQPGAVJO&psc=1
06:07 PM XXCoder: who?
06:07 PM JT-Cave: take a guess...
06:08 PM XXCoder: t4nk? only guy who spoke besides me? or i doubt it, but tom? heh
06:08 PM JT-Cave: ah not Tom
06:11 PM JT-Cave: chow time here
06:11 PM XXCoder: later :)
06:11 PM XXCoder: oh yes skunkworks if you are an afol, bricklink might be good
06:12 PM XXCoder: just make sure review feedbacks and such. i used to buy and sell there.
06:22 PM Tom_L: i'm doomed!
06:32 PM XXCoder: in what way?
06:33 PM Tom_L: talking about black lists ...
07:09 PM _unreal_: ya just finished stuffing my face
07:23 PM roycroft: well i see the usps are back to their new normal behavior
07:23 PM roycroft: multiple parcels that were "out for delivery", according to emails sent to me by the post office, did not arrive for the second day in a row
07:24 PM roycroft: not to mention the first class mail
07:39 PM CaptHindsight: roycroft: similar here, maybe it will get back to somewhat normal after the postmaster general gets replaced with someone competent at improving mail service vs hindering it
07:39 PM _unreal_: roycroft, quit your bitchen you'll get yerrrr shit when theeee feelll like it
07:49 PM XXCoder: capt indeed
07:53 PM CaptHindsight: tjtr33: I "assumed" that someone working on software stepping using the ARISC would follow working examples and ask why if they didn't see why
07:54 PM _unreal_: haaa hahahah god this guy is dumb https://www.youtube.com/watch?v=UoOQHKB3W2s
07:56 PM roycroft: the issue, _unreal_, is that i'm on the very end of my letter carrier's route - i live on a dead-end street, and the end of the street and the end of the route is 1/2 block awy
07:56 PM roycroft: and the new policy is that not a single second of overtime will be authorized
07:56 PM roycroft: so at 4:45 pm, whatever is left on the route goes back to the post office to be requeued for the next day
07:57 PM roycroft: usually my letter carrier is less than a block from my hosue at that time
07:57 PM roycroft: so my stuff that was out for delivery saturday was out for delivery today
07:57 PM roycroft: and will be out for delivery tomorrow
07:57 PM roycroft: and every day until things get caught up
07:58 PM _unreal_: :)
07:58 PM _unreal_: then you need to move your mail box closer
07:59 PM _unreal_: OMG. i just looked at that guys other videos DAMN HE'S DUMB
08:00 PM _unreal_: OMF.....G...... https://www.youtube.com/watch?v=yvM0f2N8_Ag
08:00 PM _unreal_: LOL
08:00 PM roycroft: what we need is a postmaster general who is interested in getting the mail delivered, and not in sabotaging the postal service because he believes it is competing with his private company that he still illegally owns
08:02 PM roycroft: and we should have that soon, but i won't promise not to complain again between now and then about it
08:03 PM roycroft: i'll promise not to make a daily occurance
08:05 PM _unreal_: LOL I dont know why but that lasty video I just postd I burst out laughing when it ended
08:05 PM _unreal_: LOL
08:05 PM _unreal_: DAMN THAT WAS FUNNy
08:05 PM _unreal_: I had to give him a thumbs up
08:05 PM _unreal_: LOL
08:37 PM _unreal_: well I was going to mill something but the fucking netbook shit the bed again
08:37 PM _unreal_: an other force reboot
08:38 PM _unreal_: well there goes my night. prob going to take an hour LITTERALY to boot
