#linuxcnc Calendar

01:04 AM IchGucksLive: morning from cold germany
01:11 AM IchGucksLive: off 2 school
02:30 AM gloops: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
02:30 AM gloops: anyone used that?
02:54 AM CaptHindsight: gloops: many times
02:56 AM gloops: ok thanks, so it works ok
02:56 AM gloops: (not for me for someone else)
02:57 AM CaptHindsight: has every time I've tried
02:57 AM CaptHindsight: if the kernel finds the LPT port
02:57 AM CaptHindsight: or is told where
05:30 AM jthornton: morning
05:31 AM jthornton: dang finally got all my cameras working in Motioneye
05:40 AM Tom_L: 63°F
05:40 AM Tom_L: kindof a surprise
05:53 AM Deejay: utf8 fail detected again
05:54 AM Deejay: i see only a question mark instead of a degree sign
06:05 AM jthornton: works for me
06:42 AM Longbow: Hello! any expert in servodrives here? :)
06:43 AM Longbow: I have a chinese SG-30A servodrive and it is rated at 3x220v ac; but here I have 3x380v ac. Can I just wire it up with single phase 220v?
07:31 AM gloops: there are people here who know Longbow, will answer when theyre around
07:32 AM sync: Longbow: it says so right in the manual
07:33 AM Longbow: it is difficult to understand
07:34 AM Longbow: RST are for 220v 3 phase and r t is for single phase for controller only not the power ??
07:35 AM Longbow: I can try with single phase 220v but I then loose some power? or not? :)
07:35 AM sync: depending on the motor design you will loose some speed
07:35 AM sync: but you need to connect RS and rt to 230V
07:36 AM Longbow: yes, RS and rt
07:36 AM Longbow: DO I loose speed or power?
07:37 AM Longbow: eitherway if it works without a transformer it's all good for a start :)
07:39 AM sync: as I said, you can loose speed, depending on the design
07:40 AM sync: torque you won't loose
07:42 AM Longbow: ok. Thank you for the answer then.
07:42 AM Longbow: I will try with single phase :)
09:19 AM Loetmichel: [Evil scientist laugther] "MUHAHAHA... IT LIVES!!!!!" just found my old HP Probook 6550b in my BMW Convertible with the leaky roof. IN the passenger foot well... under 5cm of rainwater. took it out, dismantled it, aibrlastet al the water out, doused it in Isopropanol alcohol, airblasted again, put it back together, plugged it in: works. HDD has a lot of read erros, no loss, was still a rotating
09:19 AM Loetmichel: one... but the rest works flawlessly... MAN HP builds their stuff sturdy!
09:23 AM SpeedEvil: hah
09:28 AM jym: Loetmichel: Remind me NEVER to let you borrow anything ;)
09:29 AM Loetmichel: jym: i only do that to MY stuff
09:29 AM Loetmichel: borrowed stuff will return in as good or better condition as when borrowed.
09:29 AM Loetmichel: the lazy handly is just with my stuff
09:30 AM jym: Loetmichel: That's not lazy, that's outer abusive ;) lmao
09:30 AM jym: outright*
09:30 AM Loetmichel: and of course: its one of 11 working notebooks i own. so it wasnt missed for quite a while. i just noticed today when starting the BMW engine (to charge the battery) that it was sitting in the passenger footwell... under water.
09:31 AM jym: Loetmichel: Unless of course you are using it for target practice =)
09:32 AM Loetmichel: nope
09:33 AM Loetmichel: i was using it to google how to reset the Canopy motors on the convertible the last that i remember.. thats why i forgot it in the car when i pared it for the winter at the company
09:33 AM Loetmichel: parked
09:33 AM jym: Loetmichel: Just curious, can you even use it for target practice in .de ?
09:34 AM Loetmichel: no weapons permit... so only with bow and arrow or a slingshot.
09:34 AM jym: Loetmichel: Eeeesh
09:36 AM jym: Heh, I was exporing and came across three kids (and their Dad) target practicing. Kids were actually pretty good too.
09:36 AM Loetmichel: There was a time when i was not that bad either
09:37 AM Loetmichel: back in my 20ties i had a friend who owned a .45 "peacemaker" replica. with 12" barrel 1040m/s V0 ammo...
09:38 AM Loetmichel: ... was quite fun to go to the range with that.
09:38 AM Loetmichel: a bit unwieldy for conealed carry though ;9
09:38 AM Loetmichel: +c
09:38 AM jym: Eh, I'd love a Judge... Accepts 45 and 410 shells =)
09:39 AM jym: Loetmichel: https://www.taurususa.com/product-details.cfm?id=199&category=revolver
09:40 AM Wolf__: those are cool, but semi pointless imo 410 shell out of something that short is meh
09:40 AM Loetmichel: ... it had a hell of a kickback, too
09:40 AM Loetmichel: :-)
09:41 AM jym: Wolf__: https://www.midwayusa.com/product/2900393924/winchester-pdx1-defender-ammunition-410-bore-2-1-2-3-disks-over-1-4-oz-bb-shot
09:41 AM Loetmichel: the ammo manufacturer claimed that it penetrated 1.5" steel armor. and i can belive that, considering its weight and speed
09:42 AM Wolf__: physics is neat, I put 3-4mm deep dimples in a AR500 plate at 100yrs with 52gn bullets
09:42 AM Wolf__: wasn’t trying to either…
09:42 AM Loetmichel: not bad for a .45 partial steel jacket (hollow point?) i think
09:43 AM jym: Wolf__: This seems to agree with you... http://www.thefirearmblog.com/blog/2016/03/17/shouldnt-use-410-shotshells-defense/
09:43 AM Wolf__: I kinda doubt that claim on that 45 pistol ammo, seeing 300win mag wont penetrate 1/2” AR500…
09:45 AM jym: Wolf__: To be honest, I like the idea of a 410, but haven't shot/played with a 410 to get any real idea of it's capabilities/drawbacks
09:46 AM jym: Wolf__: 12ga is everywhere, but the happy medium is 20ga, but not as abundant imo
09:46 AM Wolf__: happiest medium is 16ga IMO but that really isnt everywhere
09:47 AM Wolf__: I sold mine years ago. Still regretting the
09:47 AM Wolf__: that*
09:47 AM jym: Wolf__: There's the savage too, hybrid 22 and 410,
09:48 AM jym: Though I'd rather have a 1022 takedown instead
09:48 AM Wolf__: I use to have one of those also, but it was 22mag/20ga
09:48 AM jym: 22 magazine? really?
09:48 AM Wolf__: 22 magnum/20ga over/under savage
09:49 AM jym: ah, bummer. 22 magazine + 20ga sounds very interesting
09:49 AM Wolf__: https://i.imgur.com/6Z05R7g.png my friendly looking 12ga =)
09:50 AM jym: Wolf__: winchester?
09:50 AM Wolf__: benelli/beretta
09:50 AM jym: ah. I knew not mosberg (whee the safety is right in the middle)
09:50 AM Loetmichel: whats that called when the bullet has a "cup" of steel but the lead is showing at the (flat) front side?
09:51 AM jym: hollow point?
09:51 AM Wolf__: usually its copper jacket, so jacketed flat point or hollow point
09:51 AM Wolf__: *semi jacketed
09:52 AM Loetmichel: yeah, then semi jacketed
09:52 AM Loetmichel: flöat point
09:52 AM Loetmichel: flat
09:52 AM Wolf__: https://i.imgur.com/bdRoiSd.jpg =]
09:52 AM Loetmichel: wrong side open
09:53 AM Loetmichel: the bullets from that revolver were open at the "business" end
09:53 AM Wolf__: yeah, those are 5.56 bullets
09:53 AM Wolf__: box of 6000
09:53 AM Loetmichel: they were meant to mushroom
09:53 AM Loetmichel: on impact
09:54 AM jesseg: that or fragment?
09:54 AM Loetmichel: mushroom
09:54 AM Loetmichel: it wasnt hardenened steel
09:54 AM Wolf__: the hollow points are made to expand/transfer energy quickly
09:54 AM Loetmichel: yes, that
09:54 AM jesseg: ahh ok some hollowpoints fragment
09:55 AM Loetmichel: i think the german term is "mannstoppend"
09:55 AM Wolf__: I reload my own ammo for about 30 different calibers
09:55 AM Loetmichel: (slow down in first target)
09:55 AM Loetmichel: i dont know how that works with that impact energy though
09:56 AM Wolf__: mass + velocity, larger surface area will slow down/transfer energy quicker
09:57 AM Connor: Anyone know how to calculate the size of a breaking resistor ?
09:57 AM * Wolf__ guesses math?
09:58 AM Wolf__: larger than the motor wattage maybe
09:58 AM jesseg: Connor, often times the VFD will tell you what size to use -- because ultimately the VFD controls how much power gets sent to the breaking resistor, so if you have a manual it's worth a quick read, otherwise what's the model? maybe we can fnd manual online
09:59 AM Connor: I have a digital version of the manual..
09:59 AM Wolf__: you might be able to guess it using volts and wattage
10:00 AM Connor: Currently using 100W - 100ohm, it works most of the time.. but not on e-Stop because the drive tries to stop too quickly..
10:00 AM jesseg: Connor, great! (about having the manual)
10:00 AM jesseg: Connor, 100 ohm only sinks 2 amps at 200 volts...
10:00 AM Wolf__: whats the motor size? V/A/W?
10:00 AM jesseg: not a very fast stop for a motor that has a starting current of 40 amps :P
10:01 AM Wolf__: just need 2
10:01 AM Connor: 1.5Hp, 220v, 60hz, 4.3amps
10:01 AM Wolf__: 946W motor
10:02 AM jesseg: with an LRA of 20-40a
10:02 AM jesseg: and an estop from full speed would pretty much be LRA right?
10:02 AM Wolf__: you would think
10:05 AM * roycroft hopes connor is using a braking resistor, not a breaking resistor
10:05 AM Connor: Looking through the manual.. lots of talk about the braking resistor.. not much about the sizing..
10:06 AM Connor: @roycroft yes.. yes.. I spelled it wrong..
10:06 AM jesseg: Connor, well in general answer to your question (How to calculate) - The resister needs to be able to pass several times operating motor current at a fraction of operating voltage (because as rpm reduces so does voltage..)
10:07 AM roycroft: vfds generally don't dump the full load to the resistor, though, from what i understand
10:07 AM gregcnc_: they don't necessarily have to
10:07 AM Loetmichel: jesseg: it dosent need to do that for long though
10:08 AM pcw_home: You need to consider the rating of the braking transistor/IGBT
10:08 AM gregcnc_: first DC bus needs to saturate
10:08 AM roycroft: right
10:08 AM Loetmichel: i used 2kW halogen burners from floddlights as brake resistors with good results.
10:08 AM roycroft: it's kind of like the runaway ramps on mountain passes
10:08 AM jesseg: so you want to be able to brake at 10 amps at 50 volts as a minimum, so that would be 5 ohms
10:08 AM roycroft: a truck uses its own brakes to slow down
10:08 AM Loetmichel: AND you can SEE the energy dumped ;)
10:09 AM roycroft: and the ramp absorbs the remaining forward momentum to finish stopping the truck quickly
10:09 AM pcw_home: electric stove elements are also commonly used
10:09 AM gregcnc_: 5 ohms braking resistor?
10:09 AM jesseg: as far as watts, it needs to be kind of big because it has to handle the stored energy in the rotating motor..
10:09 AM pcw_home: 5 Ohms will likely explode the brake transistor...
10:10 AM Connor: What's REALLY stupid is.. It WAS breaking on e-stop before I ran the systems auto-calibrate. (However, I was getting some other funky stuff like a run-away drive at times during a quick forward, stop, reverse)
10:10 AM jesseg: gregcnc_, oh good someone who has the answer! What resistance would you use?
10:10 AM pcw_home: DC bus on a 240V system will be ~360V
10:10 AM jesseg: oh do they boost the motor voltage up for braking?
10:11 AM Loetmichel: only on a single phase input VFD
10:11 AM gregcnc_: rectified AC
10:11 AM Loetmichel: on a 3phase input dc bus will be around 625V
10:11 AM Loetmichel: for a 230V threphase
10:12 AM jesseg: I mean I know they have 339v (US single phase) that is used as a source to drive the motor, but during braking mode, as the motor slows, and is only generating 100v, is that boosted up to 339 as well?
10:13 AM Loetmichel: jesseg: usually the VFD puts ONE phase on a low DC so you have a static field inside the motor, which compells the other phases to generate enough voltage to lift the DC bus voltage
10:13 AM Loetmichel: the brake resistor as i know it is usually on the DC bus, not on the motor
10:13 AM gregcnc_: AB powerflex $ drives spec 60Ohm min
10:14 AM gregcnc_: for the 240V drives
10:14 AM Connor: gregcnc_: URL?
10:14 AM jesseg: so maximum 1 amp into the braking resistor?
10:14 AM gregcnc_: no
10:15 AM gregcnc_: ~360V DCbus into 60 Ohm
10:15 AM gregcnc_: look up regen braking
10:15 AM jesseg: oh LOL my font made it look like 600 hm
10:15 AM gregcnc_: yeah missed a space, my typing is bad
10:17 AM * Loetmichel has seen a siemens micromaster literally explode
10:17 AM jesseg: What went wrong with it Loetmichel ?
10:17 AM gregcnc_: http://ab.rockwellautomation.com/Drives/PowerFlex-4#documentation
10:17 AM gregcnc_: probably dead short in estop mode
10:17 AM Loetmichel: ... my bad, made a small config error. dc braking without resistor and moved the %dc decimal point a bit much right
10:18 AM jesseg: ahh...
10:18 AM Loetmichel: first time spinning the motor up to 400Hz and then braking...
10:18 AM Loetmichel: *BANG*
10:18 AM jesseg: wow lol
10:19 AM Loetmichel: just saw blinking "DC bus OV" on the display for a split second before the fet blocks went flying into little fragments
10:19 AM Loetmichel: ALL of them
10:19 AM gregcnc_: At some RPM regen braking is weaker than DC praking.
10:19 AM sync: jesseg: the resistor tries to keep the bus at the max voltage
10:19 AM Connor: Just got a email from the VFD manufacturer.. they said I could double up the braking resistor.. (in parallel) so, would drop it to 50hm and up it to 200w
10:19 AM sync: which is why it needs to pass quite some current
10:19 AM sync: yes, 50 ohm is reasonable
10:19 AM gregcnc_: but i'm sure some of these details are specific to the drive design
10:20 AM sync: probably even less, depending on the load
10:23 AM Tecan: https://www.ebay.ca/itm/1pcs-5-Axis-CNC-Breakout-Board-For-Stepper-Driver-Controller-mach3/201414938686
10:24 AM gregcnc_: right, as drive kW increase on a given voltage, the resistor decreases Ω and increases W
10:28 AM Connor: the 100W 100 ohm is normally recommend 1.5KW and 2.2KW, In theory, the power of the braking resistor is consistent with the braking power. But in consideration that the de-rating is 70%, you can calculate the power of the braking resistor according to the formula 0.7 x Pr = Pb x D. 
10:28 AM jdh: exaxtly
10:29 AM gregcnc_: much depends on the application
10:37 AM Connor: Oh. When I did the auto-tune, I converted HP to kW 1.5HP = 1.11kW
10:39 AM Connor: but, Ohms law says.. 220v @ 4.3amps = 946Watts
10:39 AM Connor: so, which is it?
10:40 AM gregcnc_: 4.3A is what?
10:40 AM Connor: What the name plate says on the motor for 220v in @ 60hz
10:41 AM IchGucksLive: hi
10:41 AM gregcnc_: three phase
10:41 AM IchGucksLive: Tecan: still on
10:41 AM Connor: yes
10:41 AM IchGucksLive: Tecan: https://www.youtube.com/watch?v=I00ArvYvZgI
10:42 AM Tecan: https://www.ebay.ca/itm/Mach3-USB-CNC-Modbus-E-Cut-Expansion-Card-Breakout-Interface-Board-for-Engraving/172937912583
10:42 AM Tecan: i posted wrong link
10:42 AM Tecan: these are neat
10:42 AM gregcnc_: connor http://www.ecmweb.com/basics/calculating-single-and-3-phase-parameters
10:42 AM Tecan: one guy mentioned its neat there is a led for every pin
10:43 AM IchGucksLive: Tecan: i use lots of this board
10:43 AM Tecan: great to hear
10:43 AM Tecan: works with linuxcnc well then i take it ?
10:44 AM Tecan: all i need is a usb to rs485 port adapter ?
10:44 AM IchGucksLive: Tecan: where in the world are you there are lots of fakeboards out
10:44 AM Tecan: canada
10:44 AM IchGucksLive: you shoudt ask xxcoder he uses them in canada
10:46 AM Tecan: its ebay you can usually always get your money back.
10:46 AM Tecan: does it work well with linuxcnc though ?
10:46 AM Tecan: i recall seeing it having modbus support
10:47 AM Connor: .7 PF gets me around 1.14kW @ 220v 4.3amps
10:47 AM IchGucksLive: Tecan: it works for extension output pins
10:48 AM XXCoder: I don't live that far north
10:49 AM gregcnc_: lol I was going to ask why you go to Canada to use them
10:49 AM XXCoder: huuuh thats very different board
10:49 AM XXCoder: Tecan: usb is not and never will be rt
10:50 AM IchGucksLive: XXCoder: its only a in out extencion no move
10:50 AM IchGucksLive: XXCoder: same as modebus vfd
10:51 AM XXCoder: cool
10:51 AM IchGucksLive: more pins for the world
10:52 AM XXCoder: all pins we can eat
10:52 AM XXCoder: more sensors and whatever I guess could be installed
10:52 AM IchGucksLive: if you combine all 2 blocks you can buy a 7i76 full RT cheeper
10:52 AM IchGucksLive: 3blocks
10:53 AM IchGucksLive: and then you are up on 24V industrial
10:54 AM IchGucksLive: and im off 2 :-) later
10:55 AM Tecan: is usb3 fast enough to be realtime ?
10:55 AM malcom2073: It's not about speed, it's about jitter garuntees
10:56 AM XXCoder: usb has no cpu int it cannot be realtime.
10:56 AM sync: wat
10:56 AM pcw_home: The drivers are so complex that its unlikely they can be real time
10:57 AM XXCoder: pcw_home: lack of cpu int makes it impossible.
10:57 AM sync: it'd be interesting how usb-c with pcie fares
10:57 AM sync: no XXCoder
10:57 AM sync: you can do realtime on a cpu that has no ints at all
10:57 AM pcw_home: No int better for real time
10:57 AM sync: realtime just means that your task will absolutely positively finish in a certain time
10:57 AM malcom2073: anything with usb, has some sort of processing capabilties on the other side (cpu)
10:58 AM malcom2073: however, the communication is not realtime, thus unless the cpu on the other side is doing timing, the whole system cannot be realtime
10:58 AM XXCoder: yeah though usb have no way to ensure that?
10:58 AM pcw_home: better if all critical LinuxCNC real time was synchronous (ints are horrible for real time)
10:58 AM Tecan: modbus must be using some kind of processor anyway
10:58 AM malcom2073: USB has no way to ensure anything, it's a hardware protocol. The drivers however, do not ensure that
10:58 AM Tecan: seems to do ok
10:59 AM malcom2073: modbus has pretty strict timing requirements
10:59 AM malcom2073: (over both can, and 485)
10:59 AM XXCoder: ok, seems thts another area of knowledge im bit out of date on. whee
10:59 AM XXCoder: thanks all
11:00 AM sync: no, it always was like this, it never changed
11:00 AM sync: :)
11:02 AM pcw_home: Yeah PCIE on USBC cables would be nice not sure if it will become common though
11:02 AM sync: well, it already is quite common
11:02 AM sync: although usbc is a shitshow because it basically just specifies the connector
11:02 AM pcw_home: Thunderbolt is
11:02 AM malcom2073: Is USB3 low latency enough for that to work? I know the mesa->PC connection has less strict latency requirements
11:02 AM sync: and you can do lots of shit through it
11:04 AM pcw_home: Well as a bare connector its fine but Ive only seen official support for Thunderbolt
11:04 AM sync: huh
11:04 AM pcw_home: no bare PCIE
11:05 AM Loetmichel: malcom2073: usb is per definition not good for anything low latency.
11:05 AM Loetmichel: the protocol allows for delays up to 1 sec
11:05 AM Loetmichel: there IS a "streaming" mode however
11:05 AM Rab: If you're farming out the real-time execution to an external processor or FPGA, as in the case of mesa->PC, you can get away with a lot. There are strategies for using USB or even serial to send commands to an external processor which executes them at scheduled intervals.
11:05 AM malcom2073: Rab: Linuxcnc still closes the control loop onboard the PC though, so there are still some timing requirements
11:06 AM malcom2073: Unfortunatly
11:06 AM sync: if one has usb 3.1 and usb c DFP you should get pcie lines routed to it
11:06 AM sync: malcom2073: depends on the hardware
11:06 AM Rab: malcom2073, point taken. The commercial solutions I know of work differently.
11:07 AM sync: our drives close the loop in the drive, you only need to satisfy the hostmot driver
11:08 AM sync: theoretically you could run it even slower than 1kHz if you wanted
11:09 AM malcom2073: Over step/direction? Or did you get the special serial link working?
11:09 AM sync: > step/dir
11:09 AM malcom2073: Right
11:09 AM sync: we are just using sserial
11:09 AM malcom2073: Ohhh
11:10 AM Rab: IIRC, some guy made an AVR-based dongle which worked that way...I think he was hoping for EMC2 support but there was resistance because the firmware was closed-source.
11:10 AM malcom2073: That's cool that you got it working
11:10 AM sync: through our own ethernet attached card
11:10 AM malcom2073: Someday I want to get my servos running
11:10 AM Tecan: bought a modbus setup , going to give it a shot
11:10 AM sync: doit
11:11 AM malcom2073: Need monies for your drivers, and I need to get with you for BSS support heh
11:12 AM sync: biss? that is not that hard to do
11:12 AM malcom2073: yeah
11:14 AM pcw_home: a bit harder than SSI since its source synchronous
11:23 AM XXCoder: forgot how much MESA board costs
11:23 AM jesseg: well now I've got a bullcalf on my kitchen floor in front of the woodstove
11:23 AM XXCoder: isnt it 100 to 500 or something
11:23 AM fragalot: XXCoder: ~200 iirc
11:23 AM fragalot: depends on the model though :P
11:26 AM XXCoder: yeah
11:27 AM fragalot: jesseg: how long does it have to ripen?
11:28 AM jym: ripen bullcalf?
11:28 AM fragalot: good eating, no?
11:29 AM jym: more tender iirc
11:29 AM jym: Nothing a bad piece of meat 14 hours in a smoker couldn't resolve =)
11:30 AM jym: I've found that beef just doens't have the flavor it once had 10+ years ago
11:30 AM jym: Mind you, this is all store bought
11:30 AM fragalot: depends on where you get it from, yeah
11:31 AM jym: I've tried grass fed, don't care for the flavor
11:31 AM fragalot: the local butcher here has his own delicious bunch
11:31 AM jym: fragalot: Where's "here" ?
11:31 AM fragalot: belgium
11:32 AM jym: ah, the EU also has a "no gmo" policy too, so that might be a factor

11:35 AM jym: Tecan: http://www.nvcnc.net/nvum.html
11:36 AM jym: Tecan: And are you using MACH?
11:37 AM jym: Tecan: https://forum.linuxcnc.org/38-general-linuxcnc-questions/33538-nvum-nvem-ethernet-controller
11:37 AM Tecan: maybe in virtualbox :)
11:38 AM jym: Tecan: to VIRTUALLY machine stuff? lol
11:38 AM fragalot: you can't run it in a VM
11:38 AM fragalot: not reliably, anyway
11:39 AM XXCoder: if machine dont need rt it would be fine maybe lol
11:39 AM jym: Tecan: I'm going to guess it has a windows-only driver
11:43 AM jym: Tecan: Ok, it's a "NVEM.dll" plugin for mach that needs to be installed.
11:45 AM Tecan: the ethernet one might be easier than doing usbdumps
11:45 AM Tecan: plus its 200khz
11:46 AM Tecan: same price roughly
11:46 AM jym: Tecan: Here's a thread I found... http://www.cnczone.com/forums/controller-cards/315210-cnc-forum.html
11:47 AM jym: Tecan: Please realize, for a PERSONAL perspective, I try to avoid anything propritary if I can. I've been bit on the ass far too many times both technically and financially, in both professional and personal use.
11:47 AM jym: from a *
11:48 AM Tecan: thats why i was hoping this modbus solution works :)
11:48 AM methods_: but jym does enjoy being bit on the butt i heard
11:48 AM Tecan: it even says usb in the ebay title
11:48 AM jym: methods_: Nit bit, but bite. At least get your facts straight.
11:48 AM methods_: not saying any names but it was XXCoder that told me that
11:49 AM jym: Not*
11:49 AM malcom2073: heh
11:49 AM methods_: heheh

11:50 AM sync: fragalot: I run linuxcnc a lot in a vm
11:50 AM sync: works very well
11:51 AM jym: sync: and make chips too?
11:51 AM sync: yes
11:51 AM Tecan: cheeper on ebay, its only 66 cdn
11:51 AM jym: sync: really?
11:51 AM sync: yes
11:51 AM jym: sync: what mobo/system do you have?
11:51 AM sync: I just renice the vm and it works reasonably well
11:52 AM sync: some older xeon machine
11:52 AM jym: single? ram?
11:53 AM sync: it is a single cpu, 128G of ddr3 now
11:53 AM XXCoder: https://ae01.alicdn.com/kf/HTB1gXBqgNuaVKJjSZFjq6AjmpXaW/2018-NVUM-NVEM-CNC-Controller-3-4-5-6-Achsen-MACH3-Ethernet-schnittstelle-Bord-karte-200.jpg
11:53 AM jym: sync: ASSHOLE! lmao
11:53 AM sync: why?
11:53 AM JT-Shop: XXCoder: what are you doing up in the middle of the day?
11:53 AM jym: sync: with 128G you can load even the host os into ram =)
11:53 AM XXCoder: JT-Shop: bit screwed up sleep hours
11:54 AM jym: sync: I'm a ram whore =)
11:54 AM sync: I could, but I'm not doing that
11:54 AM jym: sync: I WISH I could have 128G =)
11:54 AM sync: it just sits on a nvme ssd, but that makes no difference
11:54 AM sync: then get 128G
11:54 AM XXCoder: thats a lot of pins
11:54 AM XXCoder: enough to control 6 axis, spindle, and theres lots of opins
11:55 AM sync: I need to upgrade to some epyc machine soon tho
11:55 AM jym: sync: Oh it's not the ram itself, it's soemthing that supports it (I'm just envous is all )
11:55 AM XXCoder: lots inputs
11:55 AM XXCoder: it uses ethernet how low jitter can be with that?
11:55 AM jym: sync: ECC?
11:55 AM sync: no, it did not come with ecc ram
11:55 AM jym: XXCoder: you can use a crossover
11:56 AM sync: you can also just run it through a switch
11:56 AM sync: I do that as well
11:56 AM XXCoder: okay though still not sure how realtime it can be
11:56 AM jym: I'd prefer a vlan if thourhg a switch
11:57 AM jym: XXCoder: ask pcw_home
11:57 AM sync: very, a switch doesn't add a lot of overhead
11:57 AM fragalot: sync: what latency does that get - and what do you use for I/O?
11:58 AM jym: If sync can get realtively good results under VM, and ppl are using USB, I'm beginnign to wonder how "real time" you really need?
11:58 AM fragalot: sync: and also - what's the host OS? :P
11:58 AM sync: the host is linux
11:58 AM jym: sync: what distro?
11:58 AM sync: I'm talking to an stm32f4
11:58 AM fragalot: jym: USB typically means that the realtime part is moved to the usb device
11:59 AM sync: no idea what latency, I'd have to look again
11:59 AM sync: but it was up there
11:59 AM sync: still good enough
11:59 AM sync: you really notice when I renice the thread
11:59 AM jym: fragalot: Not sure, usb3 has come a long way
11:59 AM sync: I guess I could add a second ethernet card and just mmap it into the vm if I really wanted
12:00 PM sync: then it should have host-like performance
12:00 PM jym: sync: what host distro?
12:00 PM sync: archlinux, in this case
12:00 PM fragalot: jym: I still don't think USB3 supports realtime packets?
12:00 PM jym: k
12:01 PM jym: fragalot: What I'm trying to say is "realtime" may not actually be needed
12:01 PM sync: but I don't think the distro matters a lot
12:01 PM fragalot: jym: realtime is needed. Realtime != fast.
12:01 PM jym: fragalot: ...comparatively to a dedicated FPGA as a example
12:01 PM jesseg: fragalot, etc.,: OK guys here's my new baby. Born to a small mother on a cold snowy day, not yet sure if he'll make it but at least he's able to stand up and walk around now. https://imgur.com/a/vMXJ5
12:01 PM fragalot: an FPGA is fast, not necessarily realtime
12:01 PM jym: fragalot: Uh, I don't believe that the case
12:02 PM Tecan: whats funny was the best installable distro of linux to run on a teclast x80 tablet sofar was linuxcnc
12:02 PM jym: ferdna: I could be wrong, but from what I understand of FPGA it can do parallel processing
12:02 PM Tecan: debian installer worked really nice
12:02 PM JT-Shop: jesseg: nice
12:03 PM jym: jesseg: AWESOME!!!!
12:03 PM IchGucksLive: hi
12:04 PM fragalot: hey IchGucksLive
12:04 PM IchGucksLive: fragalot: did you take care to unload the condensers after poweroff
12:04 PM jym: jesseg: BEST OF LUCK for you and the little guy =)
12:04 PM jym: he's cute too =)
12:05 PM IchGucksLive: on 60V you can die RIP ral quick
12:05 PM fragalot: IchGucksLive: they drop down to 3V quick and then slowly unload in about a minute.
12:05 PM fragalot: IchGucksLive: yeah - for that reason i'm going t oput a piece of lexan over the terminals so I can't accidentally touch 'm
12:05 PM IchGucksLive: fragalot: may be the auto devoltige from m the psu
12:06 PM fragalot: maybe
12:06 PM jym: You could add a drain resister too
12:06 PM fragalot: jym: I certainly could, but I don't think there is a need
12:06 PM IchGucksLive: as you already checked it then it is save
12:07 PM jym: fragalot: 1M would prevent that SON OF A BITCH mode =)
12:07 PM jym: fragalot: when you ick it that is =)
12:07 PM jym: lick*
12:07 PM fragalot: what the hell is going on with my network connection
12:08 PM jym: fragalot: Did you want me to stop replugging in your connectin?
12:09 PM fragalot: no
12:09 PM Rab: From the delimiters in your hostname, it appears you are connecting from a different cyberspace.
12:09 PM fragalot: I want you to stop unplugging it in the first place
12:09 PM fragalot: Rab: great, that means I need to increase the delay for my hostmask to get set too :P
12:11 PM fragalot: anyway, jym, if I were to add a drain resistor, for it to drain the capacitors in a reasonable amount of time, say, 5 seconds, it would need to be approximately 200 ohm, which, at 60V, would draw 300mA continuously, and disspiate 18 Watts
12:11 PM fragalot: alternatively, I would need to add a relay with an NC contact powered from the 24V bus
12:11 PM fragalot: so.. I'm happy that there is already something in place that empties them :D
12:19 PM jesseg: thanks jym :D
12:22 PM * Tom_L wiggles fragalot's interweb cable some more
12:23 PM fragalot: ._.
12:29 PM IchGucksLive: im off Gn8
12:35 PM Loetmichel: fragalot: why bother with 5 seconds?
12:35 PM fragalot: Loetmichel: i'm not, that's what i'm saying
12:35 PM Loetmichel: is there a risk that anyone could touch the bus in that short time after switching the machine off?
12:35 PM fragalot: they discharge by themselves in that time, so I don't have to do anything
12:35 PM Loetmichel: usually 30 or even more seconds are acceptable for a drain resistor
12:36 PM fragalot: 30 seconds would still need a 2W resistor
12:36 PM fragalot: that's all heat I don't want :P
12:38 PM jym: fragalot: I still say a 1M resistor is better than nothing. even if it takes days
12:38 PM fragalot: I don't need anything extra, either the PSU or the drive are already draining it
12:39 PM jym: fragalot: Well, your first project... Carving your headstone ;)
12:40 PM fragalot: jym: what's the point in putting a 1M resistor in parallel with a 3k resistor in the psu?
12:41 PM jym: fragalot: I wasn't aware there was already a drain in place.
12:41 PM fragalot: i keep saying it already drains in less than 5s :P
12:41 PM jym: fragalot: What, you think we are actually listening to what you are saying?! Eeeeesh
12:44 PM gloops: new strain of elm tree introduced to the UK today, disease resistant, UK lost 66 million elm trees to Dutch Elm Disease - more trees than there are people here
12:44 PM fragalot: jym: the cap has a 25k internally too
12:44 PM fragalot: (equivalent)
12:45 PM jym: fragalot: lick it... FOR SCIENCE!!!
12:45 PM fragalot: hell no :D
12:46 PM jdh: does that line ever work for you?
12:50 PM Loetmichel: jym: i dont think that line EVER worked unless you are kyle hill ;)
12:58 PM CaptHindsight: just FYI VBX is selling shaft couplings http://www.vxb.com/NBK-Shaft-Couplings-s/1336.htm
01:01 PM Rab: Wonder if that's eBay grade stuff with a markup.
01:02 PM Tom_L: the ones with the red plastic look like the ones i got on ebay
01:02 PM Tom_L: but they work
01:02 PM fragalot: hehe. "zero backlash...at low torque"
01:03 PM jym: fragalot: I'm calling bullshit... http://i.imgur.com/nVXcTkS.jpg
01:04 PM gloops: slip or snap rating 1.9Nm
01:05 PM CaptHindsight: Rab: no they even have good stuff http://www.vxb.com/NBK-Japan-MFB-12C-4mm-to-5mm-Bellows-type-Coupling-p/mfb-12c-4mm-5mm.htm
01:06 PM Rab: CaptHindsight, I see.
01:08 PM CaptHindsight: lower prices than McMaster, then again who costs more than MCMaster
01:09 PM jym: fragalot: Bottom right corner... https://i.imgur.com/EMFLIhQ.jpg
01:10 PM gregcnc_: does anyone use hsmxpress edit backplotter to verify linuxcnc paths generated in hsmxpress/SW?
01:10 PM fragalot: jym: :-)
01:10 PM gregcnc_: i forgot why I didn't use it but the post makes good linuxcnc paths, but the backplotter is completely useless
01:11 PM jym: fragalot: See, at least when I talk shit, I back it up with proof =)
01:11 PM fragalot: jym: no
01:11 PM fragalot: you told me to lick it
01:11 PM jym: fragalot: Did you?
01:11 PM fragalot: even though there are numerous of advisory statements to NOT do so
01:12 PM jym: fragalot: and walking across the street causes cancer too
01:13 PM jym: fragalot: but ya gonna cross the street aint ya ;)
01:13 PM fragalot: no
01:13 PM fragalot: there's chickens there
01:13 PM fragalot: >.>
01:13 PM jym: lies, all lies!
01:13 PM fragalot: chickens cross the street all the time!
01:13 PM jym: fragalot: JT-Shopronded em all up
01:15 PM fragalot: you say that, but there were some spotted around gloops
01:17 PM jym: fragalot: That's just rumor, they were really lizards in chicken clothing
01:18 PM fragalot: that's.. not better
01:18 PM XXCoder: chickens is dinsours
01:19 PM jym: all birds are really
01:20 PM XXCoder: yep
01:20 PM gloops: i did get the 5 local chickens advertised on facebook at the weekend heh, everybody wanted them, nobody went to collect, seller got pissed off and said WANT GONE ASAP
01:21 PM gloops: so i stepped in
01:23 PM gloops: ill get some pics - one looks like this http://img.izismile.com/img/img2/20091201/chicken_across_the_world_00.jpg
01:25 PM Tom_L: wtf is that
01:25 PM fragalot: gloops: do you live near high voltage power lines?
01:26 PM gloops: nope, silkie chickens, bantams, very small, very tame, you can just pick them up they dont run off, cant fly either
01:27 PM gloops: they do look a bit mini-saurus
01:28 PM gloops: unlike other birds the feathers dont knit together, they stay in single strands, like hair - hence no flight
01:29 PM XXCoder: breeding can get strange features like this https://i.pinimg.com/originals/30/30/29/303029afa3bb7f39c6dacdb0680b0a73.jpg
01:30 PM gloops: oh yeah what do they call those now, like tumbler pigeons
01:30 PM XXCoder: theres another one with HUGGGE chest and head is halfway down back
01:31 PM gloops: things like that used to be BIG hobbies in europe, thousands of fanatical bird fanciers with huge shows staged
01:31 PM gloops: many strains died out now
01:32 PM Tom_L: go to Cayman and you can get all the free range chickens you want
01:35 PM gonzo_: or tesco
01:36 PM gloops: its different meat to supermarket chickens
01:39 PM JT-Shop: hmmm a pullet has been in the nest box for going on 3 hours now...
01:40 PM gloops: supermarket chickens are reared in 8 weeks, even less, fed purely on fishmeal
01:40 PM gloops: the meat is soft and many grey areas, soft fat and so on
01:40 PM gloops: with a free running cockerel it might be a year before going in the pot
01:44 PM Deejay: ah, delicious
01:47 PM gloops: yes
01:48 PM gloops: only thing is if you keep cockerels for the pot youve got problems stopping them scrapping, especially if hens around
01:58 PM XXCoder: completely seperate lot and hiding hens away from view would work?
02:00 PM gloops: suppose it depends on the breed, its their instinct to kill one another, and they do
02:01 PM gloops: usually best if they have plenty of space, to escape
02:03 PM XXCoder: interesting
02:06 PM fragalot: fit them all with little chainmail vests
02:08 PM gloops: some of the old miners used to keep fighting birds, (all dead now, miners and birds) they used to seperate them in small cages, keep them in the dark, feed them raw meat only, the birds were highly wound up, if you touched the cage they thwacked it automatically, very aggressive things
02:11 PM XXCoder: I saw one about putting chickens in virtual sociel envorment
02:12 PM fragalot: o.O
02:12 PM fragalot: do they wear tiny VR googles?
02:12 PM XXCoder: lemme find it
02:12 PM XXCoder: well yeah
02:12 PM XXCoder: wide open spaces, zero stress
02:12 PM fragalot: figuring out the best positioning for those must have been fun
02:12 PM XXCoder: yeah
02:12 PM fragalot: then when they misbehave you run the rollercoaster VR
02:12 PM XXCoder: https://www.extremetech.com/extreme/182595-virtual-reality-for-chickens-is-the-future-of-farming-but-is-it-also-the-future-of-humanity
02:12 PM fragalot: :D
02:13 PM fragalot: aw it's a spoof :(
02:14 PM XXCoder: ah missed that
02:14 PM XXCoder: but interesting idea nevertheless
02:14 PM XXCoder: happy chickens is healthier
02:14 PM XXCoder: with complete containment dieases cannot spread, so no antibontics
02:15 PM gloops: yes, pretty dire conditions supermarket chickens are kept in, and battery hens for eggs, all pumped with antibiotics its in their drinking water
02:24 PM XXCoder: yeah
02:25 PM XXCoder: yet we need MASSIVE amount of meat to keep us fed
02:25 PM XXCoder: vat meat is growing but not there yet
02:25 PM Deejay: fat
02:25 PM fragalot: XXCoder: but we CAN print meat!
02:25 PM fragalot: all you do, is you get a blender
02:25 PM fragalot: blend up some steak
02:25 PM fragalot: put the steak in an extruder
02:25 PM fragalot: and print your burger!
02:26 PM XXCoder: lol
02:26 PM XXCoder: so wheres that meat come from :P
02:26 PM fragalot: well it's beef, so cows.
02:26 PM fragalot: but 3D printing the meat is the future so it's fine
02:30 PM gloops: population of earth during the stone age
02:31 PM XXCoder: we cant maintan techogical soceity with such low population
02:31 PM gloops: we can with robots
02:32 PM fragalot: gloops: the issue is that half the population scorew below average when it comes to technical knowledge
02:32 PM gloops: global population cap - 10 million
02:33 PM XXCoder: nah more likle billion or so
02:33 PM gloops: fragalot it doesnt really need many people with tech knowledge to maintain and advance technology
02:33 PM XXCoder: earth can support around 100 billion or more, with advances on food and medicine
02:33 PM XXCoder: but I want to keep other life around also
02:34 PM gloops: it might be argued that you need to produce 10 million people to find one notable scientists or mathematician, but that can be solved, by eliminating some genes
02:35 PM gloops: XXCoder 100 billion - is that standing room only? lol
02:36 PM XXCoder: hardly
02:36 PM XXCoder: earth is big.
02:36 PM XXCoder: its still less thn 10% density of most compact city of all
02:36 PM gloops: richard dawkins did the 'standing room only' calculation, cant remember the figure now
02:38 PM fragalot: gloops: 60,282,311,822,360
02:39 PM gloops: yes thats it, couldnt remember whether the last 3 digits were 360, or 630
02:39 PM fragalot: XXCoder: bear in mind, gloops is from the UK. His billion is larger than yours.
02:39 PM XXCoder: ah yes million million = billion there
02:39 PM XXCoder: in usa its merely million * 1000
02:40 PM gloops: that makes your billionaires sound bigger than ours XXCoder lol
02:40 PM fragalot: gloops: either is within rounding error anyway
02:41 PM roycroft: and a billion is a buttload
02:41 PM roycroft: so that must mean that brits have bigger butts than americans
02:41 PM roycroft: 1000x bigger
02:41 PM fragalot: roycroft: no, because the UK has far less billions than the USA does
02:42 PM XXCoder: so for uk there is no billionaires yet lol
02:42 PM fragalot: I mean
02:42 PM fragalot: in debt alone
02:42 PM gloops: "For instance, the present population of Latin America is around 300 million, and already many of them are under-nourished. But if the population continued to increase at the present rate, it would take less than 500 years to reach the point where the people, packed in a standing position, formed a solid carpet over the whole area of the continent. This is so, even if we assume them to be very skinny - a not very unrealistic
02:42 PM gloops: assumption. In 1,000 years from now they would be standing on each other's shoulders more than a million deep. By 2,000 years, the mountain of people, travelling outwards at the speed of light, would have reached the edge of the known universe."
02:42 PM XXCoder: lol
02:43 PM XXCoder: thats unmoderated exponental growth
02:43 PM fragalot: gloops: that's assuming that wifi hasn't made everyone infertile by then
02:43 PM gloops: well something has got to give
02:44 PM fragalot: everything has a bell curve
02:44 PM fragalot: we're just on the rising edge of it now
02:45 PM XXCoder: most first world countries is at less than replacement rate of breeding
02:45 PM XXCoder: japan is one of worse ones at 0.6
02:45 PM XXCoder: thats why they have serious problems making elderly is supported, theres just not enoygh people
02:46 PM gloops: the big cull is coming
02:46 PM XXCoder: oh another one of those world is ending nutters
02:47 PM gloops: XXCoder thats the native people, in europe the populations are growing, despite low native birthrates
02:47 PM XXCoder: so, what people is those supposed cull is for?
02:49 PM gloops: oh the usual, the poor, the weak, the unready
02:49 PM XXCoder: ah the usual ethitic cleasing
02:49 PM gloops: famine, war
02:49 PM XXCoder: I dont support such, for any reason, ever.
02:50 PM gloops: unavoidable isnt it
02:50 PM XXCoder: nope
02:51 PM gloops: what do you propose to prevent it? to prevent masses of uncontrolled reproduction outstripping avialable resources?
02:51 PM fragalot: gloops: the population crowth in europe is nearly stagnating....
02:51 PM fragalot: and the % growth globally is starting to slow down
02:51 PM gloops: fragalot our population has increased 10 million in 20 years
02:51 PM gloops: 1/6th
02:52 PM XXCoder: yeah when people dont worry about dying early or children dying early, guess what? people have less kids
02:52 PM XXCoder: the huge boom is due to transition from lots kids dying, to having lots kids but very few die, and now we are entering post-boom, fewer kids.
02:53 PM gloops: even as it stands, you cant provide for the rest of the world as the west lives now
02:53 PM fragalot: gloops: yes, because there was a high % in the 50's, which has steadilly declined ever since.. granted with the babyboom, the effect of 1% has grown
02:53 PM gloops: if everyone in china wanted a car youd need another planet earth
02:53 PM fragalot: XXCoder: indeed
02:53 PM gloops: immigration fragalot, and reproduction by immigrants
02:54 PM fragalot: gloops: immigration really isn't such a big deal as you make it out to be
02:54 PM fragalot: not from a statistical pov
02:55 PM gloops: here watch this https://www.youtube.com/watch?v=6-3X5hIFXYU scary sht
02:56 PM fragalot: might as well get your facts from the onion
02:56 PM gloops: the basic principles of that video is right
02:56 PM fragalot: currently 12% of the worlds population lives in europe, and this is projected to fall to 7% by 2050
02:56 PM fragalot: even with immigration
02:57 PM XXCoder: lol that video
02:57 PM XXCoder: know what scares me more?
02:57 PM XXCoder: trending anti-science in usa
02:58 PM fragalot: ^
02:58 PM gloops: trending anti-science? how about trending old pagan desert religions?
02:59 PM XXCoder: like christians?
02:59 PM Rab: haha
02:59 PM gloops: christianity isnt an old bedou religion
02:59 PM XXCoder: muslim is offshoot from chistian, which is offshoot from jews
02:59 PM fragalot: actually
03:00 PM gloops: i see your country is mentioned in the video fragalot, 50% of all newborns are muslim in belgium
03:00 PM fragalot: wasn't paganism originally from the UK?
03:00 PM XXCoder: I missed couple stops but essentally yes
03:00 PM fragalot: gloops: hahahahahaa
03:00 PM XXCoder: fragalot: yep!~
03:00 PM XXCoder: celtic
03:00 PM fragalot: 50%. of all newborns. in belgium. muslim.
03:00 PM fragalot: really
03:00 PM fragalot: I'm sorry gloops but you need to get your head out of your ass.
03:00 PM XXCoder: the tree gift giving and such in xmas is from celts
03:00 PM gloops: that might be the case, but we gave up head hunting a long time ago
03:01 PM gloops: you can deny it fragalot, and i am not getting involved in anything to do with race or politics anyway, but deep down you know its true
03:03 PM fragalot: gloops: it's about as true as the "no-go" zones in the UK mentioned by US politicians
03:03 PM gloops: what? there are no go zones here, plenty of them
03:03 PM gloops: and in belgium also
03:04 PM fragalot: well yeah you aren't allowed entry in nuclear plants, but that's not what they meant
03:06 PM gloops: how about sweden?
03:46 PM Deejay: gn8
04:03 PM gloops: pity he didnt keep the nuts - https://www.ebay.co.uk/itm/SMALL-LOT-OF-BALL-SCREW-MATERIAL/263496526254?
04:06 PM Rab: gloops, maybe balls are all over the workshop floor.
04:07 PM Rab: Just the screws (no model/brand) makes matching a project.
04:08 PM gloops: my guess is he bought screws 2 ft longer than rails, those are the offcuts
04:08 PM gloops: Rab if you can find cheap nuts thats a bargain
04:09 PM gloops: doesnt look like chinese 1605 to me, those are expensive, c2 ballscrews
04:17 PM gloops: big screw https://www.ebay.co.uk/itm/THK-ballscrew-3300mm-long-32mm-diameter-32mm-travel-per-rev-unused/122966137141?
04:19 PM gloops: even at 3 metres, the ballscrew is capable of 11200mm/min
06:46 PM Alkabal_: hi all
06:46 PM Alkabal_: http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m19
06:47 PM Alkabal_: it is needed for lathe configuratiob with DC motor and encoder ?
07:00 PM CaptHindsight: M19 Spindle orientation requires a quadrature encoder with an index to sense the spindle shaft position and direction of rotation.
07:01 PM CaptHindsight: Alkabal_: what do you want to do?
07:04 PM Tom_L: CaptHindsight have you done spindle orient before?
07:05 PM Alkabal_: hi
07:05 PM Alkabal_: i have encoder AB + I
07:05 PM Alkabal_: but simple motor without stepper or servo
07:06 PM Alkabal_: so i'm not sure about set this setting to my config
07:09 PM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SpindleOrient
07:12 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/sherline.hal
07:12 PM Tom_L: that's the config i used for my spindle
07:13 PM Tom_L: the rest of the files are in that directory
07:13 PM Alkabal_: thanks
07:14 PM Tom_L: the basic connections should be the same
07:15 PM Tom_L: there is an example file to go with that first link i posted
07:15 PM Tom_L: should be in the standard install files
07:17 PM Tom_L: BeachBumPete!
07:22 PM BeachBumPete: hey tom!
07:22 PM Tom_L: what's up?
07:25 PM BeachBumPete: eh not much you?
07:26 PM Tom_L: just gettin the mill dialed in a bit
07:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A12_1st_batch.jpg
07:26 PM Tom_L: ran those last night
07:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A12_P2_2.jpg
07:28 PM BeachBumPete: Hey man those look pretty nice!
07:28 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Extra/A9_can_grip.jpg
07:28 PM Tom_L: decent finish
07:29 PM Tom_L: alot better than the sherline for sure
07:30 PM BeachBumPete: indeed
07:30 PM BeachBumPete: what are those?
07:34 PM Tom_L: parts to hold a spray can
07:35 PM roycroft: did you make those on that mill you've been building recently?
07:35 PM Tom_L: yes
07:35 PM roycroft: you're pretty ambitious :)
07:35 PM BeachBumPete: thats kickass
07:35 PM roycroft: i didn't expect you to have that thing in service already
07:36 PM Tom_L: https://www.youtube.com/watch?v=lNJXA3Qv2i4&t=6s
07:37 PM Tom_L: https://www.youtube.com/watch?v=LO2AvRVU0iE&t=19s
07:37 PM roycroft: i guess if you needed it to make money that's a pretty strong motivator
07:37 PM Tom_L: meh, it's mostly a hobby
07:38 PM BeachBumPete: Oh so you just put a sherline spindle assy on it then
07:38 PM Tom_L: yeah for now. i had it :)
07:40 PM Tom_L: and quite a few tool holders for it
07:40 PM BeachBumPete: subbed
07:40 PM BeachBumPete: looks like it has a bunch of y huh
07:40 PM Tom_L: yeah
07:41 PM Tom_L: more than i'll use but that's what the ballscrew kit had
07:41 PM Tom_L: i did cut one of them down some
07:41 PM BeachBumPete: screw that man just build a stout block to bring that head in a bit and use all of that real estate you got now ;)
07:42 PM Tom_L: i wanted the reach for the other side
07:42 PM BeachBumPete: what are your actual travels
07:45 PM Tom_L: 17 x 13 x 7
07:45 PM BeachBumPete: nice
07:45 PM BeachBumPete: what was your sherline?
07:45 PM Tom_L: could have more Z
07:45 PM Tom_L: like 7 x 9 by very little z
07:46 PM Tom_L: that plate i put on it is off the sherline and it would barely cover that
07:46 PM Tom_L: on that part i ran 2 fixture offsets just to try it
07:46 PM Tom_L: set the tools and the G54 55 offsets and let it rip
07:47 PM Tom_L: swapped programs and hit go
07:47 PM Tom_L: works great
07:47 PM Tom_L: the vise is G55
07:47 PM BeachBumPete: congrats man nice job
07:47 PM Tom_L: the plate is G54
07:47 PM Tom_L: thanks
07:47 PM Tom_L: it was a fun build
07:47 PM BeachBumPete: come on over and help me finish mine now ;)
07:47 PM Tom_L: hah
07:47 PM Tom_L: if you were close i would
07:48 PM BeachBumPete: I know you would
07:48 PM BeachBumPete: Still tinkering on the control panel in the electronics enclosure
07:48 PM Tom_L: that trough around the table is it's cutting limits
07:48 PM Tom_L: i put that in for a drain
07:49 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Coolant_Drain2.jpg
07:49 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Coolant_Drain1.jpg
07:49 PM BeachBumPete: been getting acclimated in the new job and working a bit of side work lately not much time for the CNC retrofit
07:49 PM BeachBumPete: been making rails and other parts tho.
07:49 PM Tom_L: and put those pegs in for alignment if i ever want to
07:49 PM Tom_L: yeah i figured you still were
07:51 PM Tom_L: haven't seen zee around much either
07:54 PM BeachBumPete: oh you mean ol hobbit hands ;)
07:54 PM Tom_L: hah
07:54 PM BeachBumPete: the company I am working for just leased a second building that is like 10k sq ft and they are adding two CNC's supposedly
07:54 PM BeachBumPete: one will be a large format flatbed CNC router
07:54 PM BeachBumPete: the other will be a CNC 4 axis mill probably a HAAS or something
07:54 PM BeachBumPete: I am apparently the only one there other than the owner that knows anything about CNC stuff so they want me to do most of the design, setup, and programming of things so it should get real interesting here very soon.
07:54 PM BeachBumPete: I am kinda excited about it hoping things go well there.
08:02 PM Tom_L: what kind of software do they have?
08:02 PM Tom_L: or plan to get
08:02 PM Tom_L: my kid's got a copy of the latest mastercam. he's learing it in his cad classes
08:03 PM Tom_L: probably limited somehow
08:03 PM BeachBumPete: not sure just yet. a lot will depend on the model of machine they get. He seems to like the thermwood machines and they use their own controls
08:05 PM Tom_L: the mill probably wouldn't be
08:06 PM BeachBumPete: I know
08:06 PM Tom_L: i got a refresher course on my 3d package on that part
08:06 PM BeachBumPete: I might see if they like mastercam becasue I have used it a good bit
08:06 PM Tom_L: it's been a while since i did any 3d stuff
08:06 PM Tom_L: it's pretty standard
08:07 PM Tom_L: i haven't looked at the new one
08:10 PM tiwake: BeachBumPete: hi
08:10 PM BeachBumPete: hey tiwake!
08:34 PM Crom_: I got the 33686 moving on it's own power today on X, Going to have to work on things to get Y permanently powred. I'm going to have to make a belt drive for it, to put the stepper off the side.
08:41 PM Crom_: using 8-32 screws it's easy enought to mill a 2mm slot to the NEMA24 motor, to allow the screws to line up with the NEMA23 mount
09:47 PM dioz: fuck i wish fusion 360 would work on linux
09:47 PM dioz: works on mac!
09:47 PM dioz: why the fuck no linux?
10:13 PM Crom_: My stepper is too long for Y and X, going to making stand offs to mount stepper on outside. using paulcnc kit
10:16 PM Crom_: down the road, I'll have to make belt drive adapters to move stepper further away from shaft to allow handle use
10:17 PM Tom_L: you don't need handle use if you have a pendant
10:17 PM Crom_: hmmm... true... I'll have to get a pendant for it
10:18 PM Crom_: what's a decent one for linuxcnc, MESA 7192M or USB?
10:18 PM Crom_: 7i92M
10:18 PM Tom_L: i made mine just using gpio on a mesa card with one encoder input
10:20 PM Tom_L: so i've got 2 encoders, one for the spindle and one for the pendant
