01:40 AM Deejay: moin
04:14 AM Tom_L: morning
05:00 AM mrec_: god that makes me angry now ... I'm cutting an item in a loop and linuxcnc suddenly spits a following error on Z
05:00 AM mrec_: what is that shit doing .... I can't even restart the NC code
05:00 AM mrec_: this is not even a closed loop system
05:02 AM mrec_: this crap should not do that
05:02 AM mrec_: either it should not even work from the beginning on but don't stop in the middle ...
05:03 AM mrec_: whoever has programmed this has implemented a very evil bug into linuxcnc
05:18 AM JT-Cave: morning
05:44 AM miss0r2: morning
05:45 AM mrec_: again .. this time 75%
05:45 AM mrec_: this is a big fuckup in linuxcnc
05:45 AM mrec_: its an openloop system
06:07 AM miss0r2: JT-Cave: I was just handed a Michilin MCL-450 today. well.. it was sat by a dumpster, and I asked about it. They just told me to get rid of it :D BRAND SPANKING NEW, never opened. The unit itself was still covered in waxoil and vacuum packed in pastic. I found an exact one online: https://www.chinahao.com/product/542571689326/
06:07 AM miss0r2: it is in an almost prestine travel case, with all the tools and even a set of dressing diamonds to do wheel shapes ect :D
06:07 AM * miss0r2 feels lucky
06:13 AM JT-Cave: wow
07:56 AM miss0r2: I just got back from the local screw & bolt pusher. I got their remaining 3/8"BSF by 3/8" grub screw (74 total) but it came in a nice packet labelev 'UMBRAKO SOCKET SCREW CO. LTD. ... This box is older than I am :D the size/type is even stamped on the label.
07:57 AM miss0r2: They always provide excellent service those guys :)
08:00 AM JT-Cave: what will you use them on?
08:01 AM miss0r2: the oil filter consoles. As a good service I've added two outlets for a pressure switch(not optional) and a oil pressure gauge(optional). so I will blind off one of the two holes with such a screw
08:02 AM miss0r2: with the 'old' style ones you had to buy a t-block to get both
08:11 AM JT-Cave: sounds like someone in here has anger management issues or a configuration error
08:35 AM JT-Shop: time to start solving today's puzzles
11:05 AM unterhaus_: some days I shouldn't read the mailing list
11:06 AM unterhaus_: makes me understand why some companies refuse to support mach
11:08 AM pcw_home: mrec_: if you get a following error its usually a setup problem or hardware issue
11:22 AM JT-Cave: lunch minute is up time to go back to work
11:23 AM * roycroft is just now having breakfast
11:23 AM roycroft: i've had a busy morning at work so far
12:26 PM mrec_: pcw_home: I lowered the speed on the A axis and it's okay now.
12:27 PM mrec_: I milled two more sprockets and they're fine
12:29 PM mrec_: https://snipboard.io/Rsf0j2.jpg
12:50 PM JT-Shop: sounds like the stepgen max accel or max vel is too low for the a axis max accel or vel
12:51 PM JT-Shop: weird sprockets!
01:03 PM Tom_L: happy day
01:03 PM Tom_L: damn it's getting chilly out

01:14 PM CaptHindsight: Tom_L: one of those days where the temp drops by 20+ degrees in minutes?
01:23 PM mrec_: JT-Shop: for pulling an smd belt
01:24 PM -!- #linuxcnc mode set to +v by ChanServ
01:24 PM mrec_: I'm already thinking about adding a 5th axis to my mini mill it just works so well.
01:26 PM unterhaus_: I just got an email about how the mechanical engineering department is keeping students up to date with arduinos
01:27 PM CaptHindsight: unterhaus_: well they did revolutionize manufacturing when they started using them in 3D printers
01:28 PM unterhaus_: don't get me started
01:29 PM unterhaus_: I think it's fine to use arduinos in this role, but they have been doing it for as long as they had a mechatronics class
01:29 PM unterhaus_: late 1990s maybe?
01:31 PM unterhaus_: so these students will go out and have a boss that used an arduino in a course years ago
01:32 PM CaptHindsight: I heard that the GRBL lovers have reached some form of success with closed loop synchronized motion
01:32 PM CaptHindsight: rigid tapping might be working
01:34 PM CaptHindsight: i have found no evidence to support this, only rumor
01:38 PM CaptHindsight: I have used a ^duino a few times on a commercial project since it just dropped in and worked but it wasn't really low cost
01:39 PM CaptHindsight: the breakout boards with no IO protection cost more than the Chinese Mega's
01:45 PM CaptHindsight: https://www.controllino.com/product/controllino-mega/ €279.00 excl VAT
01:46 PM CaptHindsight: https://industruino.com/shop/product/industruino-ind-i-o-d21g-2?category=2 139.00 €
01:48 PM CaptHindsight: https://www.sferalabs.cc/product/iono-arduino/ €135.00 – €199.00 + tax
01:50 PM CaptHindsight: https://www.industrialshields.com/shop/product/017001000100-spartan-arduino-plc-19r-i-os-analog-digital-2216 190.00 €
01:52 PM unterhaus_: I thought grbl couldn't drive a 4th axis, spinning would be good enough
01:53 PM unterhaus_: I don't think I would spend 200 bucks on an arduino
01:53 PM unterhaus_: nanos and associated terminal breakouts were pretty cheap
01:53 PM unterhaus_: cheaper than buying relays with timers
01:54 PM CaptHindsight: yeah, I think it is for people that prefer the Arduino IDE vs typical ladder logic tools from a PLC vendor
01:55 PM CaptHindsight: https://www.youtube.com/watch?v=zuDK-uluB6g
01:55 PM CaptHindsight: GrblGru: 5-axis CNC machine controlled with Mega-5X
01:55 PM CaptHindsight: https://www.youtube.com/watch?v=D6gUH47ayn0
01:55 PM CaptHindsight: blGru: 5-axis CNC machines controlled with g2core
01:56 PM unterhaus_: well, mega doesn't cost $20 for 4 axis
01:58 PM CaptHindsight: https://github.com/synthetos/g2 g2core - The Next Generation
01:59 PM CaptHindsight: g2core is a 9 axes (XYZABC+UVW) motion control system designed for high-performance on small to mid-sized machines
01:59 PM unterhaus_: that's cool though, he used 2 cnc shields with spaghetti wiring
02:00 PM unterhaus_: due is like a mega only different?
02:01 PM CaptHindsight: http://synthetos.com/
02:01 PM unterhaus_: there is a thread on the lcnc forum about how to recreate lcnc
02:02 PM unterhaus_: without all the nasty complexity, I guess
02:02 PM CaptHindsight: heh yeah, I dragged out one on the ml last year
02:02 PM CaptHindsight: new and popular is what seems to drive those interested
02:02 PM unterhaus_: the ml is one thing, but having it on the forum seems a bit much to me for some reason
02:03 PM CaptHindsight: nah get it all out
02:03 PM CaptHindsight: beat the subject to death
02:03 PM CaptHindsight: get them to really get down to the nuts and bolts and they quiet down
02:03 PM unterhaus_: it has occurred to me that nml is not really necessary now
02:04 PM unterhaus_: the thread guy is showing results, so he's not all talk
02:04 PM CaptHindsight: they seem to be under the impression that it's a rather easy task but they don't have the time or skills
02:04 PM unterhaus_: easy task, but only interested because they don't understand how lcnc works
02:05 PM CaptHindsight: or they make hyperbolic leaps from use several cheap microcontrollers to "it should work"
02:05 PM unterhaus_: there was a ml thread where someone basically was lamenting that no dev would modify lcnc to work with smart drivers
02:06 PM unterhaus_: just this week. Basically rehashing the grbl discussion
02:06 PM unterhaus_: but I see no reason for lcnc to add a gcode sender
02:06 PM CaptHindsight: someone recently asked about machinekit and the magic and sauce that would break the GUI from the controller in LCNC
02:07 PM CaptHindsight: did they ever achieve this?
02:07 PM unterhaus_: you can do it with lcnc
02:07 PM unterhaus_: send nml over net
02:08 PM CaptHindsight: yeah NML can be replaced, but who will write this?
02:08 PM unterhaus_: well, it worked better 15 years ago before some dev added a couple megabytes to the message
02:08 PM unterhaus_: it has been done with lcnc
02:09 PM unterhaus_: I have considered it and decided there is no reason
02:09 PM unterhaus_: The argument for MK was to use an accepted network standard
02:10 PM unterhaus_: someone was working it with lcnc recently and found that the message was too big
02:12 PM unterhaus_: problems with rtai development are going to mean all userspace soon, I imagine
02:13 PM CaptHindsight: works well enough with new PC's
02:14 PM CaptHindsight: too much drama with RTAI
02:15 PM CaptHindsight: no funding to keep RTAI going
02:17 PM CaptHindsight: TomP is working on getting the stepgen going on the Allwinner (Opi's) that John Kasunich wrote years ago
02:18 PM CaptHindsight: so an Rpi with software stepping into the 100K's/sec and a GPU that supports >40fps at HD res
02:20 PM CaptHindsight: someone else has interest in similar for the Rock64 (rk3399)
02:23 PM CaptHindsight: Falling out of love with GRBL https://www.youtube.com/watch?v=i8eRitzcDOI
02:25 PM CaptHindsight: Demo of 6 Axis Grbl_ESP32 https://www.youtube.com/watch?v=RVi9n5H70DY
02:28 PM CaptHindsight: https://www.ebay.com/itm/4-Axis-Motion-Controller-Offline-CNC-500KHz-CNC-Standalone-Control-DDCS-V3-1-/143183874710
02:28 PM CaptHindsight: US $239.88
02:49 PM * JT-Shop gets the DUOMITE out
02:51 PM * Tom_L read that as dynamite
02:54 PM drdoc: mrec_: are those sprockets for a music box?
03:10 PM veegee: For a stepper motor with a given "holding torque" spec, I can momentarily double the torque for motion, right?
03:10 PM veegee: Obviously not for continuous use, but for a few seconds
03:12 PM pcw_home: That works with a servo, but not a step motor, a step motor will stall (slip to the next magnetic detent) if you exceed its holding torque
03:12 PM veegee: pcw_home you mean next full step?
03:13 PM pcw_home: the next 4 full steps
03:13 PM veegee: That may be acceptable
03:14 PM pcw_home: (2 phase step motors are mostly 50 pole motors so if you slip from pole to pole that's 4 full steps)
03:14 PM veegee: ah got it, thanks!!
03:14 PM pcw_home: (a full step is 90 electrical degrees)
03:15 PM mrec_: drdoc: smd belts
03:17 PM veegee: toothed sprockets are easy to machine with a single pass per tooth, yeah?
03:17 PM veegee: That is, using a vertical mill and rotary table/dividing head
03:18 PM mrec_: well I have two passes
03:18 PM mrec_: final pass is to make it round
03:18 PM mrec_: round tip.
03:20 PM mrec_: the more difficult part will be the gears for it
03:20 PM mrec_: and that everything aligns
03:45 PM drdoc: pcw_home: I'm told you might be able help me with a smoked Mesa 6i25
03:47 PM drdoc: I plugged in a direct-powered video card that damaged the motherboard and the Mesa board. Now, in a working system, lspci doesn't list it at all
03:47 PM CaptHindsight: drdoc: if it actually released the smoke you will have to send it back for repair and a refill
03:48 PM drdoc: ah
03:48 PM drdoc: somebody here recommended asking Peter about it
03:48 PM drdoc: so I am ;)
03:48 PM CaptHindsight: sure, but if it really did smoke..
03:49 PM CaptHindsight: smoke means R & R, repair and refill :)
03:50 PM drdoc: I can't see any damage, but if it doesn't ID on the bus, I think it's safe to assume
03:50 PM drdoc: refill?
03:50 PM * drdoc can't find the tasnk
03:50 PM drdoc: tank
03:51 PM drdoc: this project is just snakebit
03:52 PM drdoc: my roommate closed the garage door yesterday while I was in the bathroom and destroyed both the door's top panel and a lead screw assembly
03:53 PM CaptHindsight: refill is a joke about refilling the smoke inside the parts that burned up
03:53 PM drdoc: no idea yet why the opener's failsafe didn't trigger
03:53 PM drdoc: ahhh
03:53 PM drdoc: still can't find the tank though
03:54 PM CaptHindsight: "The 6I25 should configure its FPGA within a fraction of a second of power
03:54 PM CaptHindsight: application. If the FPGA card fails to configure, both red LEDs on the right hand side of
03:54 PM CaptHindsight: the card will remain illuminated after power up. If this happens the 6I25s EEPROM must
03:54 PM CaptHindsight: be re-programmed via the slow GPIO bitbanged method with SMFLASH."
03:56 PM CaptHindsight: but if LSPCI is not even aware of the device on the bus it's likely that you have far more wrong with the board
03:59 PM CaptHindsight: drdoc: what is the direct powered video card that you mentioned?
04:01 PM CaptHindsight: did this somehow cross 12V power with 3.3V?
04:05 PM pcw_home: That would be bad...
04:05 PM miss0r2: uhoh
04:06 PM pcw_home: Our proto 5I24 cards had a interplane short between 1.2V and PC 3.3V. The FPGA glowed like a volcano...
04:10 PM Connor: Which ISO do I need for Ethernet MESA cards?
04:10 PM Connor: PREEMPT-RT ?
04:19 PM pcw_home: Yes Preempt-RT
04:19 PM Connor: Also, is there a mirror for the ISO? It's stalled out..
04:19 PM pcw_home: Someone in Russia is making a 7I92 clone
04:20 PM Connor: Oh geez.
04:20 PM Connor: That sucks.
04:22 PM pcw_home: It fine with me
04:22 PM pcw_home: it's
04:22 PM Connor: Really?
04:23 PM pcw_home: Yeah, At this point the more LinuxCNC support, the merrier
04:23 PM Connor: Ahh.
04:24 PM Connor: So, I've got a 7i96 coming. Guy in KY purchased one and is sending it to me.. doing a build out for him.
04:27 PM XXCoder: skunkworks: your video got cited in comment lol https://hackaday.com/2021/04/07/harmonic-drive-uses-compliant-mechanism-to-slim-down/
04:27 PM pcw_home: It should be relatively straight forward, as there are GUI configurators for the 7I96

05:03 PM -!- #linuxcnc mode set to +v by ChanServ
05:27 PM unterhaus_: not sure I really am interested in the compliant mechanism version of a harmonic drive
05:28 PM unterhaus_: the nice thing about the version that skunky made is that there isn't much unnecessary plastic in the drive train
05:28 PM unterhaus_: just the gears
05:29 PM XXCoder: indeed
05:30 PM unterhaus_: am I the only person that sees GRBL and thinks "gerbil"?
05:30 PM XXCoder: i want to make one evenually, but have no use for one for now
05:30 PM unterhaus_: guy in Cap'ns video pronounced it garble
05:30 PM unterhaus_: I think I have 10 harmonic drives in the basement. Not sure what brand. Japanese though
05:31 PM unterhaus_: it's on the list
05:31 PM XXCoder: nice lol

05:31 PM XXCoder: hows your printer so far?
05:46 PM JT-Cave: make: *** No rule to make target 'config.status', needed by 'Makefile.inc'. Stop.
05:46 PM JT-Cave: not seen that error before
05:48 PM XXCoder: hmm sounds like maybe typo for entry config.status
05:51 PM JT-Cave: but I didn't touch that... I'll pull again in the am and make sure the docs build before adding iov2
05:52 PM XXCoder: ok
05:55 PM roycroft: config.status is generated by configure
05:55 PM roycroft: did you run configure before you tried the make?
05:55 PM roycroft: that is generally what creates config.status, i should say
05:55 PM roycroft: i don't know what you're trying to build, so i can't say for sure that is the issue
05:56 PM JT-Cave: thanks, forgot to run config after changing branches
05:58 PM roycroft: you're welcome
06:00 PM JT-Cave: Creating abs.mak
06:00 PM JT-Cave: make: *** No rule to make target 'config.status', needed by 'Makefile.inc'. Stop.
06:00 PM JT-Cave: hmm still failed at the same spot...
06:01 PM JT-Cave: ah a configure error
06:03 PM JT-Cave: seems ./configure needs ./configure --with-realtime=uspace --enable-build-documentation
06:03 PM JT-Cave: now
06:07 PM roycroft: sounds like you're on the path to success at least
06:07 PM roycroft: just watch for potholes and other obstacles
06:07 PM JT-Cave: yea just gotta work out the issues lol
06:08 PM roycroft: so i need to put this new server online, and my boss refused to purchase any new disks for it
06:09 PM roycroft: do i use the ssd that says it's 81% worn out, or do i use the ssd that has been in a machine for a couple years, reports zero errors, but claims to have 14 hours of power-on time?
06:09 PM XXCoder: roy wtf
06:09 PM XXCoder: why no on new dsk
06:09 PM roycroft: because he's cheap and he is incapable of seeing beyond the end of his nose
06:09 PM XXCoder: cheap is pay twice
06:10 PM roycroft: we just moved out of our old datacenter, and he wants to "use up" all the disks we already have before he'll buy any new ones
06:10 PM XXCoder: HMM
06:10 PM XXCoder: build a "data server" use all disks
06:10 PM JT-Cave: that is pretty short sighted
06:10 PM * roycroft refers xxcoder to the comments he made some moments ago about his boss not seeing past the end of his nose
06:11 PM XXCoder: well yeah thats why i said make a "data server"
06:11 PM roycroft: here's the only upside to this
06:11 PM XXCoder: its not actually used, just place it, have blinking led
06:11 PM roycroft: i'm installing mirrored ssds for the os
06:11 PM XXCoder: if asked, "oh sure its data server"
06:11 PM roycroft: and a raid10 array for the data
06:12 PM roycroft: i'll go down there some weekend when my boss is not around (he still refused to wear a mask, no matter what), gather up a pile of disks, zero them out, test them, and put the good ones on a shelf
06:12 PM roycroft: as the drives fail in this server i'm building i will probably be able to replace them before their mirror fails
06:12 PM roycroft: with zero downtime
06:13 PM XXCoder: not bad
06:13 PM roycroft: of course, he does not know this is mirrored and raid 10
06:13 PM roycroft: i'm sure he would object to that
06:13 PM roycroft: fortunately he does not know what raid10 is
06:13 PM roycroft: if he did he would declare it a waste of money
06:14 PM roycroft: but i can't count how many times i've gotten an email in the middle of the night saying a disk has failed, i sleepily go "ok, fine", go back to bed, and replace it the next morning without any downtime
06:14 PM roycroft: and disks always fail late at night or on the weekend
06:14 PM roycroft: or when i'm on vacation
06:15 PM roycroft: they never fail during business hours
06:15 PM roycroft: that's just how disks live their lives
06:19 PM Connor: Man, It's been forever, how do I set axis up to go fullscreen at startup?
06:21 PM JT-Cave: it's in the documents...
06:22 PM * JT-Cave uses QtPyVCP... much better
06:25 PM Connor: I would think it would be in the DISPLAY section.. bit, I don't see a option
06:37 PM -!- #linuxcnc mode set to +v by ChanServ
06:48 PM unterhaus_: some of the stuff on the forum is pretty confusing and looks to be outdated probably
06:49 PM unterhaus_: looks like there is an rc file for axis that you change settings in
06:51 PM Tom_L: JT-Cave, QtPyVCP requires 2.8 right?
06:51 PM Connor: Looking at qtpvcp, this would be nice for this.. https://www.qtpyvcp.com/showcase/lathe_vcps.html
06:51 PM Connor: But, I can't find THAT VCP
06:52 PM Connor: I just did the pip install qtpyvcp
06:52 PM Connor: which is confusion. I just did a clean install of 2.8.0 and updated to 2.8.1
06:52 PM Connor: and, Project URL: Included with QtPyVCP isn't helpful.. because.. it's not included from what I can tell.
06:53 PM Tom_L: https://forum.linuxcnc.org/qtpyvcp/38935-where-do-you-find-the-probe-basic-lathe-vcp
06:53 PM Tom_L: Connor,
06:53 PM Connor: JUST found the thread.
06:54 PM Tom_L: you used to be able to get to their chat from here but i don't think you can now
06:56 PM Connor: Dang it: Note: Probe Basic is currently designed for 1920x1080 screen sizes only!
06:57 PM Connor: I'm maxed at 1680 x 1050
06:57 PM Connor: I'm building this for someone else.. not sure if their monitor can do 1920x1080
06:58 PM Connor: maybe I should just stick with Axis.

07:02 PM Tom_L: Connor, he did probe basic for that large screen format
07:02 PM Tom_L: no resizing
07:02 PM Tom_L: i haven't kept up with what they're doing with it
07:04 PM Connor: Right. I'm checking with the guy whom I'm setting this up for to see what resolution his monitor supports.
07:04 PM Connor: All of mine are 1680x1050 except my 65" TV
07:05 PM Connor: Guess I could use that to do the setup... :/
07:06 PM Tom_L: or borrow his
07:06 PM Connor: He's not in the state.
07:06 PM Tom_L: or buy a new one... you know you want one
07:06 PM Connor: I'm configuring everything and getting it up and running on the desk then shipping it to him.
07:07 PM Connor: Nah. my main PC has 4 monitors in a 3-row and 1 above setup for video editing. All are the 1680x1050 matched. I'm not changing.
07:07 PM Connor: My LinuxCNC is another of those monitors..
07:12 PM Tom_L: i don't have any touch screens

07:31 PM roycroft: which is a good thing, since i have more stuff i want to put on cl
07:31 PM roycroft: and here's the metal stock rack i built last weekend:
07:32 PM roycroft: https://roycroft.us/Metal-Stock-Rack/Metal-Stock-Rack1.jpeg
07:32 PM roycroft: 2
07:32 PM roycroft: ack
07:32 PM roycroft: https://roycroft.us/Metal-Stock-Rack/Metal-Stock-Rack2.jpeg
07:32 PM roycroft: that
07:32 PM roycroft: is what i meant to do
07:32 PM roycroft: it's the perfect size for the amount of metal i store
07:32 PM roycroft: and incredibly sturdy
07:33 PM Tom_L: reminds me of those external fire escape ladders :)
07:33 PM roycroft: it's recycled ladder rack from a data center
07:34 PM Tom_L: i know
07:34 PM roycroft: the stuff that goes above the equipment racks to carry all the cabling
07:34 PM roycroft: but yeah, it does kind of look like a fire escape ladder
07:34 PM -!- #linuxcnc mode set to +v by ChanServ
07:35 PM roycroft: the rungs are nice because i don't have to worry about putting something too short on it and having it fall through, or having to lay expanded metal on top of the racks for the same reason
07:35 PM roycroft: and by not welding it i was able to preserve all that nice, thick power coating
07:38 PM Tom_L: no triangle bracing needed?
07:40 PM roycroft: i thought i'd need it, and i have some pieces that i was going to add for it, but it doesn't rack at all
07:40 PM roycroft: the bolt pattern is triangular, and that seems to be enough
07:41 PM roycroft: i even had the braces laid out, ready to cut and install, but when i got the main frame bolted up i realised it did not need any bracing
07:41 PM Tom_L: until you get substancial weight on it you won't know
07:41 PM roycroft: there's a big i-beam on it already, and a 6' length of railroad rail
07:41 PM roycroft: that's substantial
07:42 PM roycroft: and a dozen or so 10' lengths of square tubing, and quite a bit of flat bar of various sizes
07:42 PM roycroft: there's probably a half ton or so of weight on it right now
07:43 PM roycroft: but if i need to add the diagonals at some point i'll do so

10:27 PM Guest38003 is now known as _unreal_
10:28 PM _unreal_: got big progress done on my laser etcher tent
10:28 PM _unreal_: the tent is 98% done at this point
10:29 PM _unreal_: lid is fully functional with the locking supports. the safety glass is partly mounted.
10:30 PM _unreal_: tomorrow after work I need to get the tie town loops installed and a few more snap mounts done.
10:30 PM _unreal_: then I can bring it to the canvis people
10:30 PM _unreal_: I also need to get the z motor setup fixed
10:31 PM roycroft: i was going to put a safety view glass on the enclosure for my 3d printer for when i'm using the laser
10:31 PM roycroft: then i started getting prices, and i was getting quotes from $150 to $300 for a small piece of glass
10:32 PM XXCoder: what laser freq?
10:32 PM roycroft: 450nm
10:32 PM roycroft: you can calculate the frequency from that :)
10:32 PM XXCoder: very visible
10:32 PM _unreal_: what?
10:32 PM _unreal_: $150
10:33 PM XXCoder: so glass wouldnt work
10:33 PM _unreal_: ?
10:33 PM roycroft: it's coated
10:33 PM _unreal_: I got mine for $30
10:33 PM _unreal_: what kind of laser
10:33 PM XXCoder: i know, i meant just bare glass :)
10:33 PM roycroft: it's only 6w
10:33 PM roycroft: led
10:33 PM XXCoder: co2 should work with just glass as it blocks it just fine
10:33 PM roycroft: i did not call asia for prices
10:34 PM roycroft: i called american safety gear companies
10:34 PM roycroft: whose stuff is tested and certified
10:34 PM XXCoder: indeed
10:34 PM _unreal_: roycroft, https://jtechphotonics.com/?product=445nm-laser-shielding-24-x-12
10:34 PM XXCoder: when i got mine, first thing I did was throw away goggle
10:36 PM roycroft: i did not thow the goggles that came with mine away
10:36 PM roycroft: i just put them somewhere far away from the printer
10:36 PM XXCoder: lol
10:37 PM roycroft: and got some proper ones that cost almost as much as the laser
10:37 PM XXCoder: i didnt actually throw em away but i used it for webcam
