02:59 AM veegee: $300 for hydraulic power unit with variable piston pump
02:59 AM veegee: The variable piston pump is the main reason I'm interested because those things are really damn expensive
03:15 AM miss0r: capt. idiot here!
03:16 AM miss0r: Last night I was too eager to tesy out the lathe retrofit, so I failed at being an intelligent human, and fed the step controller 25volt DC to the logic power where it was supposed to only get 5
03:16 AM miss0r: needless to say, it let the magic blue smoke out
03:16 AM XXCoder1: :( sucks
03:17 AM miss0r: so, now I need to figure out how much a replacement will cost me. (emco proprietary)
03:17 AM miss0r: I just wanted to make sure the internet knows I am an idiot :]
03:18 AM sensille: no chance to repair it?
03:19 AM miss0r: well, not by me anyway. I've driven to a place that does such repairs this morning. But theres a chance that the two microcontrollers are done for. and they are programmable. if that is the case, I need to get an emco replacement
03:19 AM miss0r: even if that is not the place, such repairs do not come cheap. It will most likely set me back $1000us or more
03:20 AM miss0r: place=case
03:21 AM miss0r: I've also written an email to emco, asking for a quote for a replacement. Time will tell. What is the worst part is, I was damn near ready to run it :D and walking around at home with my arm in plaster, theres not alot of activities I can realy do...
03:24 AM Deejay: moin
03:25 AM miss0r: mornin'
04:24 AM Loetmichel: *brrr* coworker is shrinkwrapping a pallet next to me... *squeak* **squeeeal** *squeak* ... ow, my teeth!...
04:26 AM miss0r: haha
04:26 AM XXCoder1: lol
04:28 AM Loetmichel: chalk on a blackboard is lovely compared to THAT sound :(
04:39 AM miss0r: in case all attempts fail to get a replacement/repair. OR the price in beyound insanity: Can you guys recommend a good step driver than can handle 3-phase steppers?
05:02 AM JT-Cave: morning
05:56 AM Loetmichel: hehe, sittting here at the company, hearing all four 3dprinters doing brackets and stuff and the two cnc routers in the next room doing vented enclosure side panels... brombl jukkie jukkie jukkie brombl sounds like a busy company. :) https://www.youtube.com/watch?v=f54xJU6YEPo
05:56 AM Loetmichel: Enclosures are a lot better now though. https://www.youtube.com/watch?v=lm-kpV2Msn0
05:56 AM XXCoder1: good, I see no hands holding parts lol
05:57 AM XXCoder1: that looks like old stye tv lol
05:57 AM XXCoder1: certain shot
06:10 AM Tom_L: morning
06:10 AM JT-Cave: yo
06:21 AM XXCoder1: heys
06:24 AM miss0r: do you guys have any experience with leadshine stepper drivers?
06:26 AM miss0r: I was hoping gecko made a 3-phase stepper, but I am not abled to find one. and seeing as that is the only respectable stepper driver name I know, I am somewhat at a loss here
06:27 AM JT-Cave: I would have assumed that gecko would have one...
06:28 AM * miss0r am not able to find said unit
06:28 AM miss0r: that should've been an 'is'...
06:32 AM JT-Cave: AD doesn't have a 3 phase output stepper drive either
06:33 AM miss0r: this is the cheapest 3-phase stepper driver (that allows 30 volt input) on farnell... https://dk.farnell.com/trinamic/tmcm-1636-48v-tmcl/stepper-motor-12-52vdc-20a/dp/3515660
06:33 AM miss0r: ouch
06:33 AM miss0r: and I would need two... :D
06:34 AM JT-Cave: https://www.amazon.com/3MD560-Leadshine-1-axis-Stepping-Driver/dp/B00NT87JAY
06:35 AM JT-Cave: what is kr 4.501,00
06:35 AM miss0r: ~750usd
06:35 AM JT-Cave: ouch
06:36 AM XXCoder1: pw indeed
06:36 AM miss0r: Yeah, I also found that leadshine one. But I have no idea what quality to expect honnestly
06:36 AM JT-Cave: https://www.newark.com/trinamic/tmcm-1636-48v-tmcl/stepper-motor-12-52vdc-20a-rohs/dp/81AH9343?ost=tmcm-1636-48v-tmcl
06:36 AM miss0r: with the price as an indicator, nothing much I would presume
06:36 AM JT-Cave: only $513 in the usa
06:37 AM miss0r: still a good kick to the wallet
06:38 AM * miss0r hates himself for killing that original driver
06:53 AM miss0r: just heard back from the electronics repair man. They managed to lift the programming from one of the two identical stepper boards on the step controller
06:54 AM JT-Cave: cool
06:54 AM miss0r: They have the processors in question in stock, and believe they have the rest of the small fried dodads on the board in stock as well
06:54 AM XXCoder1: nice
06:54 AM miss0r: so by tomorrow afternoon I should have it back, preferably working
06:54 AM miss0r: and he told me a nice reason it failed with my 24volts..
06:55 AM miss0r: they, apparently, decided to jumper out the slot for a 7805, so safe a few pennies... Thank you emco!
06:55 AM * JT-Cave puts on his chicken suit and goes to tend the chickens
06:55 AM miss0r: (absolutly not my fault then :D )
06:56 AM miss0r: say hello to the chicks from me ;)
07:03 AM XXCoder1: glad its repairable
07:04 AM miss0r: these guys can repair *ANYTHING* I've even seen them fill out burned away board with exopy, and laying down new pads'n traces.
07:04 AM miss0r: I use them often for my professional job. so I am hoping for a private discount :D
07:04 AM Loetmichel: miss0r: ben there done that
07:05 AM Loetmichel: lots of work though
07:05 AM miss0r: yeah
07:05 AM miss0r: and expensive too. but sometimes when you are faced with an option of getting a new million eur machine or spending a few thousand EUR repairing the old one, it comes into perspective
07:13 AM Loetmichel: <- has "repaired" a dozen of special mainboards where a trace on an inner layer of the 6 layer ML board was wrong
07:14 AM miss0r: damn. the prospect of that almost makes me want to cry :D
07:14 AM Loetmichel: THAT was fun, milling down to the right layer, changing the trace and then rebuilding the "terraces" above
07:25 AM R2E4: Hey JT. c7i96 working now.
07:31 AM JT-Cave: yippie
07:31 AM JT-Cave: should work from the CNC menu as well
08:03 AM Loetmichel: hehe, funny. Just poked my left ring finger tip with an xacto knife accidentally... just to feel an immediate itch in my righ foot sole... funny how things are interconnected :)
08:03 AM XXCoder1: yeah. a nerve can cause other one to fire too
09:35 AM puff: Good morning.
09:35 AM puff: What's the best linux program to open an autocad DXF file?
09:38 AM puff: Is there a good channel for discussion of general CNC topics?
09:38 AM Tom_L: yes
09:39 AM Tom_L: you can open dxf in a text editor. it just depends what you want to do
09:40 AM gregcnc: dxf text?
09:44 AM Tom_L: you can't do much useful with it but you can open it
09:45 AM roycroft: there is a freely-available version of qcad for linux that can work with dxf files
09:46 AM roycroft: i don't like to make claims that something is "best", as that's almost always subjective and relative, but qcad does work
09:46 AM Tom_L: https://www.ubuntupit.com/free-autocad-alternative-top-15-cad-software-for-linux/
09:46 AM Tom_L: *best* is subjective
09:48 AM puff: Ok, let me rephrase the question. I need to ship an object that's about 4' x 2' x 1'. It's an odd shape. I'm thinking about using a CNC to cut out packaging fo rit. I was sent the autocad DXF files for the shape.
09:49 AM puff: While I'm on it... does a script or tool exist to do the following? Given a 3D model of an object, generate a set of 2D shapes to cut on a CNC to construct a set of supports to hold that 3D shape?
09:50 AM puff: If it doesn't exist, I'm thinking of making something like that, in the long run (not for this package, I have to ship it sooner :-).
09:52 AM puff: E.g. do a slice operation on the model, similar to slic3r, except much more spread out, one slice every n inches, and output the slices as DXFs that can then be cut on a CNC.
09:53 AM puff: Actually output the negative of the slices, so you end up cutting a set of pieces that then can be used to hold a real-world example of the 3D shape.
09:54 AM Loetmichel: make a wooden/cardboard box, spray about 1/5 of the volume remaining in the enclosure of 2k spray foam into a heavy duty trashbag, close it well. put into the box with the item do be shipped, close the box, wait a couple hours. @puff
09:54 AM roycroft: most folks just squirt expanding foam in a plastic bag inside the crate to make that kind of packaging
09:55 AM roycroft: you're overthinking this
09:55 AM gregcnc: sounds tricky to ship. void fill foam won't do the job?
09:55 AM Loetmichel: roycroft: indeed
09:55 AM gregcnc: i guess everyone has the same idea
09:55 AM roycroft: as now three people have told you :)
09:56 AM puff: That sounds helpful :-).
09:56 AM roycroft: and this not an idea that we all had at the same time
09:56 AM roycroft: i'ts a common practise that we all relayed at the same time
09:57 AM puff: Thanks.
09:57 AM Loetmichel: there are even companies that sell different sized sealed bags with a liquid and a glas ampule in them
09:58 AM puff: I'm still curious about my question, I think it'd be useful for other purposes, but.
09:58 AM Loetmichel: that foam up and harden when you break the ampule
09:58 AM puff: Neat, what search terms? ( beyond "void fill foam")?
09:59 AM Loetmichel: https://www.youtube.com/watch?v=V-WBhRpOPjk
09:59 AM Loetmichel: for example
09:59 AM Tom_L: https://www.uline.com/BL_7708/Instapak-Quick-Room-Temperature?keywords=expanding+foam
10:00 AM roycroft: to address the more general question, if you have a 3d model of an object, almost any 3d cad sofware can easily be used to make a support for the object, which you can slice into manageable chunks, and then feed the individual chunks to your slicer to generate gcode for printing them
10:00 AM Tom_L: uline has what you need if you're in the US
10:00 AM roycroft: freecad should be able to handle that for you, as one example
10:01 AM puff: Loetmichel, Tom_L: Thanks.
10:01 AM puff: roycroft: Beside slicing, any other keywords to look into?
10:02 AM puff: That is, given a 3D object, is there a common term or phrase for creating a matching negative 3D shape?
10:03 AM Tom_L: mold
10:03 AM puff: Ah.
10:38 AM Lcvette: hello all!
10:39 AM Lcvette: was wondering if anyone with a high speed retrofitted vfd or high speed router running fusion 360 and linuxcnc might have some notes to compare on some tool path issues I have been facing
10:39 AM Lcvette: primarily it is repositioning moves in adaptive, the little line segments
10:40 AM Lcvette: my machine shakes visibly and audibly during some of these moves
10:40 AM Lcvette: trying to figure out if i have a setting wrong in either linuxcnc, fusion 360 or both
10:41 AM gregcnc: if the segments are required to make the part, nothing you can do about that
10:41 AM norias: hmmm
10:41 AM norias: is there a max accel?
10:41 AM norias: or a smoothing?
10:41 AM gregcnc: some path blending can help
10:41 AM norias: there ya go
10:41 AM gregcnc: have you tried playing with G64 Pxxx?
10:42 AM norias: it just sounds like excessive accel / jerk
10:42 AM Lcvette: https://youtu.be/LDMKMx2aO5E?t=185
10:43 AM Lcvette: you can hear it, it is smooth in most places but then it does that
10:43 AM gregcnc: looks like in the rapid moves?
10:43 AM Lcvette: correct
10:44 AM Lcvette: the repositioning moves
10:44 AM gregcnc: in rapids G64 does apply
10:44 AM norias: slow the rapids
10:44 AM Lcvette: ive turned down the feed rate there but it still does
10:44 AM gregcnc: you can change those to feed moves in cam
10:44 AM gregcnc: does not apply
10:44 AM Lcvette: ok i will try setting those to high feed rate
10:45 AM * Lcvette uploaded an image: image.png (33KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/ZBFJoOiIOzoadLHrRGqiGpOO/image.png >
10:45 AM norias: can't you just set a max V in linuxcnc
10:45 AM norias: and that will stop either rapids or feeds from going too fast
10:45 AM norias: ?
10:45 AM gregcnc: you can override rapids
10:45 AM Lcvette: its not the feed, its the cam path is a bunch of small line segments
10:46 AM gregcnc: but then retracts are slow
10:46 AM gregcnc: you can fix that as well
10:46 AM norias: gregcnc: fair, but could be a quick fix
10:46 AM norias: turn it down for one run, turn it back up
10:46 AM gregcnc: quick but slow?
10:46 AM Lcvette: and i think greg nailed it with g64 not working during rapids and the cam was set for rapids on the repositioning moves there
10:46 AM norias: take the hit
10:47 AM norias: fusion 360 should have a "convert all rapids to feeds"
10:47 AM norias: and a "max feed"
10:47 AM norias: that you can change per program
10:47 AM gregcnc: look at tolerance for the adaptive path
10:48 AM Lcvette: posted a image above of the available settings
10:48 AM Lcvette: im changing to always use high feedrates
10:48 AM Lcvette: ive got that set at 0.004
10:48 AM Lcvette: changing that makes more or less line segments
10:48 AM gregcnc: messign with it you can bring down the number of pointsint he path
10:49 AM gregcnc: but really, it may come down to having too much accel for your machine
10:49 AM Lcvette: yeah i tried that first, it just changed the frequency of that shudder
10:50 AM gregcnc: and that Linuxcnc doens't have jerk control
10:50 AM gregcnc: you look at a Brother and it just rips doing stuff like that
10:50 AM * Lcvette uploaded an image: image.png (6KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/dBCGYHFtRdZQMVmiplIGJWVG/image.png >
10:50 AM gregcnc: or any machine
10:51 AM gregcnc: if you pick that it should let you set a feed rate
10:51 AM Lcvette: if path blending works with this setting for the "rapid" moves maybe that will resolve it
10:51 AM Lcvette: correct think you solved my issue
10:51 AM gregcnc: it will
10:51 AM Lcvette: i will test this afternoon when i run the part and report back
10:52 AM Lcvette: then may play with it to see if i can use the preserve axial rapid movement and assign a high feedrate for the radial moves
10:52 AM gregcnc: you may consider looking at your servo tuning during moves like that
10:52 AM Lcvette: not much there
10:52 AM Lcvette: it is running in pulkse mode
10:53 AM gregcnc: step dir?
10:53 AM Lcvette: it has an autotuning feature for the torque/table mass settings and i ran that multiple times it seems to be good
10:53 AM Lcvette: it handles G1 and G2 moves wonderfully
10:53 AM Lcvette: ie tangent arc
10:53 AM gregcnc: but they are generally much slower
10:53 AM Lcvette: very smooth
10:54 AM gregcnc: do you have encoders to look at follow error?
10:55 AM Lcvette: i do have the encodered connected to a 7i77
10:55 AM gregcnc: I'm saying, see what's actually happening during those shaky moves
10:55 AM Lcvette: i tried doing feedback mode but there was some issues where it wanted to vibrate and hunt
10:56 AM Lcvette: ah yeah not a bad idea
10:57 AM gregcnc: anyone know if tolerance can be set somewhere for rapid moves in Linuxcnc?
10:57 AM Lcvette: im pretty sure it will show some error
10:57 AM Lcvette: but it must not be big enough to trigger an alarm for the ini ferror settings
10:57 AM gregcnc: which goes back to tuning
10:58 AM Lcvette: but again, not running in feedback mode and tuning a step dir drive is kind of meh
10:58 AM Lcvette: there is not much available there
10:58 AM gregcnc: i was poking around my Emcos and they have a value for rapid tolerance
10:58 AM Lcvette: that would be nice
10:58 AM gregcnc: sure but the drive is still tuned to the servo
10:58 AM Lcvette: thats what im referring too is the drive tuning parameters
10:58 AM Lcvette: very limited
10:59 AM Lcvette: not super high end drives
10:59 AM Lcvette: from china
10:59 AM Lcvette: lol
10:59 AM Lcvette: the feedback mode had an issue with delay on the feedback
10:59 AM gregcnc: it should have normal P I D and some FF?
11:01 AM * Lcvette posted a file: k-Series Servo Drive Manual.pdf (3292KiB) < https://matrix.org/_matrix/media/r0/download/matrix.org/TgecNmrHyKreNesvcWPpZruA/k-Series Servo Drive Manual.pdf >
11:01 AM Lcvette: thats the drive manual
11:11 AM gregcnc: it looks like a capable drive. even seems to have what they call gain switch
11:11 AM gregcnc: may allow a different set of parameters for rapids, if you can get a rapid signal from Linuxcnc
01:00 PM JT-Shop: UPS just dropped off more work
01:07 PM JT-Shop: https://gnipsel.com/images/wood-working/workbench-mk1/workbench-mk1-13.jpg
01:07 PM JT-Shop: https://gnipsel.com/images/wood-working/workbench-mk1/workbench-mk1-14.jpg
01:34 PM ziper: I guess I will buy a cheaper harbor freight gear puller and grind down the jaws so that they can fit in there to pull these internal bearings
01:39 PM CaptHindsight: miss0r: over here we have for $60 https://www.automationtechnologiesinc.com/products-page/laser-machine-accessories/3-phase-3dm580-8a-stepping-motor-driver
01:41 PM CaptHindsight: warehouse in the UK and DE https://www.cloudraylaser.com/products/cloudray-3-phase-3dm580s-stepper-motor-driver-18-50vdc-1-0-8-0a-1
01:53 PM JT-Shop: automation direct had rack and pinions now
02:00 PM CaptHindsight: they also have lower quality ball, lead and belt drive positioners
02:01 PM CaptHindsight: https://www.automationdirect.com/adc/overview/catalog/power_transmission_(mechanical)/linear_motion_slides_and_actuators
02:02 PM CaptHindsight: oh sorry no belt driven
02:21 PM CaptHindsight: JT-Shop: have you used their C-More panels and software? Wondering what the GUI making software is like
02:21 PM CaptHindsight: https://www.automationdirect.com/adc/shopping/catalog/hmi_(human_machine_interface)/c-more_micro_panels/3_inch_panels_-a-_accessories
02:34 PM CaptHindsight: https://www.ebay.com/itm/LOT-OF-13-CARBIDE-FACED-BORING-BARS-5-8-SHANKS-BORITE-5-16-TO-9-16-MIN-HOLE/293975575405
02:35 PM JT-Shop: CaptHindsight, it's pretty easy, I use C more micro's all the time, just used 10 of them at the shooting range
02:35 PM CaptHindsight: JT-Shop: even to build the GUI's?
02:36 PM JT-Shop: gui for what?
02:36 PM JT-Shop: the 3" have pretty small screen lol
02:36 PM CaptHindsight: the small HMI displays
02:36 PM CaptHindsight: link above ^^
02:36 PM JT-Shop: it's pretty simple
02:37 PM CaptHindsight: ladder is ladder
02:37 PM JT-Shop: which link?
02:37 PM CaptHindsight: https://www.automationdirect.com/adc/shopping/catalog/hmi_(human_machine_interface)/c-more_micro_panels/3_inch_panels_-a-_accessories
02:38 PM JT-Shop: yea you use the same software for all the micro hmi's and a similar one for the larger hmi's
02:38 PM JT-Shop: free download you can check it out
03:09 PM miss0r: CaptHindsight: that is suspiciously cheap. I will absolutly keep that in mind if this project turns out to be hella expensive :D
03:13 PM perry_j1987: hows it going guys
03:16 PM JT-Shop: about to call it a day and go work on my workbench
03:16 PM perry_j1987: working on figuring why the axis seem discombobulated
03:17 PM perry_j1987: axis 0 is X and axis 1 is z
03:17 PM CaptHindsight: miss0r: looks like the Cloudray is a knockoff or private label of the Leadshine
03:17 PM perry_j1987: but the arrow keys on the keyboard jog in unexpected directions heh
03:18 PM CaptHindsight: perry_j1987: change the polarity in the HAL file
03:18 PM miss0r: CaptHindsight: which probably means that the leadshine one is atleast *something* as someone is taking their time to make a knockoff :D
03:19 PM CaptHindsight: miss0r: I have a few leadshine bipolar stepper drives, they are OK, tend to be noisy and not the smoothest
03:19 PM miss0r: CaptHindsight: Have you ever had a realy smooth bipolar stepper?
03:20 PM CaptHindsight: never tried the 3-phase drivers
03:20 PM miss0r: this is supposed to be one of the upsides of the 3-phase ones
03:20 PM CaptHindsight: miss0r: yes, several
03:20 PM miss0r: ahh.. its just me then :D
03:20 PM CaptHindsight: needs a good stepper driver
03:21 PM miss0r: anyway. Thanks for the link. I will call it a night. I have to get up early for a follow up x-ray in the morning. See'ya
03:21 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver
03:21 PM CaptHindsight: ^^ these are the lowest quality I used to go
03:22 PM CaptHindsight: ^^ these vs https://www.automationdirect.com/adc/overview/catalog/motion_control/stepper_systems/stepper_drives
03:22 PM perry_j1987: checking hal meter not seeing any life when i press one of the limit switches hmm
03:23 PM CaptHindsight: use the Leadshine and the motors are noisy and kind of smooth
03:23 PM CaptHindsight: use the SureStep on the same motors and they are silent and smooth
03:23 PM gregcnc: at some point you have to move beyond the config tools and code what you need yourself
03:24 PM miss0r: hmm. I don't surestep as a 3-phase option, sadly
03:24 PM miss0r: I don't see*
03:24 PM perry_j1987: gregcnc me?
03:24 PM gregcnc: yes
03:24 PM CaptHindsight: yes, so I'm not certain how smooth the Leadshine 3-phase drivers are
03:24 PM Rab: I have some Vexta pentagon drives and steppers, very smooth indeed. Not sure why that technology seems to have died out, maybe it's not competitive with modern digital drivers.
03:25 PM CaptHindsight: but $30-60
03:25 PM miss0r: at that price its worth a shot
03:25 PM miss0r: But firstly I will see how my repair dude fares.
03:25 PM miss0r: Anyway. now I am off *poof*
03:25 PM CaptHindsight: get some rest
03:25 PM perry_j1987: so config tools cant setup endstops heh
03:25 PM perry_j1987: thats not the right thinking lol
03:25 PM CaptHindsight: your thumb needs it
03:26 PM CaptHindsight: perry_j1987: with great power comes great responsibility
03:27 PM CaptHindsight: a config tool for all the features and possibilities of LCNC might be a larger project than LCNC
03:28 PM JT-Shop: yup
03:29 PM JT-Shop: endstops?
03:30 PM perry_j1987: under inputs tab i selected input 1 home & limit. joint 0 input 2 Home & limit joint 1
03:32 PM perry_j1987: input 0 is estop in
03:33 PM perry_j1987: fire up axis no life on any of the switches or estop
03:34 PM CaptHindsight: perry_j1987: how are they wired?
03:35 PM CaptHindsight: perry_j1987: what are they connected to?
03:35 PM perry_j1987: one side into the input pin and other to pin 12
03:35 PM perry_j1987: 7i96
03:35 PM CaptHindsight: if you had an actual wiring diagram it would be helpful
03:35 PM JT-Shop2: pastebin the io.hal file
03:36 PM JT-Shop2: also open show hal configuration and put the inputs in the watch window to see if your wiring is working
03:37 PM pcw_home: You need to power the inputs somehow, just connecting input common to an input will not do anything
03:39 PM CaptHindsight: and he's off again :)
03:41 PM CaptHindsight: I propose a new channel rule: post a wiring diagram and have a stable network connection
03:41 PM JT-Shop2: lol
03:42 PM Tom_L: naw dammit! that takes all the fun out
03:42 PM Tom_L: pin 12 is gnd btw
03:42 PM Tom_L: bad connections help drag the saga out for weeks!
03:43 PM Tom_L: then some (who will remain nameless) completely rewire during the outtage :)
03:46 PM unterhaus: I wish I could completely rewire during an outage
03:46 PM unterhaus: I could just log off
03:47 PM perry_j1987: gah horrible hotspot
03:47 PM perry_j1987: im back
03:48 PM perry_j1987: ok so wire one side to input other to 5v then for these limit/home switches?
03:48 PM CaptHindsight: I count three possible pin #12's on the 7i96
03:48 PM perry_j1987: the bottom row is inputs
03:48 PM perry_j1987: tb3
03:49 PM perry_j1987: but if the inputs are not pulled up then i'd have to wire one side to inputs other to 5v i gather?
03:50 PM CaptHindsight: TB3 12 INPUT COMMON
03:52 PM CaptHindsight: I'm a terrible mind reader
03:52 PM perry_j1987: he said the inputs are not pulled up
03:53 PM perry_j1987: so i dont need pin 12
03:54 PM CaptHindsight: which TWO connections to the 7i96 is the switch wired across?
03:54 PM perry_j1987: none
03:54 PM perry_j1987: its disconnected
03:55 PM CaptHindsight: are you trolling us?
03:55 PM perry_j1987: why would i do that
03:55 PM perry_j1987: im stuck out here with crappy internet trying to figure this out
03:56 PM CaptHindsight: start again, what is the problem?
03:57 PM perry_j1987: i used 7i96 configuration tool and fired up axis and trying to figure this out
03:57 PM CaptHindsight: trying to connect limit switches to a 7i96?
03:57 PM perry_j1987: aye
04:00 PM JT-Shop2: open show hal configuration and add your inputs to the watch window
04:00 PM CaptHindsight: For sinking type inputs, the input common pin is grounded and a +3 to +36V signal is applied to the input pins to activate the input.
04:01 PM CaptHindsight: For sourcing type inputs, the input common is connected to +5 to +36V and the input pins are grounded to activate an input.
04:01 PM CaptHindsight: perry_j1987: which was are you trying to connect them?
04:01 PM CaptHindsight: ^^ these are your two choices
04:02 PM CaptHindsight: was/way
04:03 PM CaptHindsight: you can not mix types of inputs
04:13 PM perry_j1987: got it
04:13 PM pcw_home: The LEDs by the inputs should illuminate if the inputs are working
04:14 PM perry_j1987: had to tie pin 12 to gnd
04:16 PM perry_j1987: not many wiring examples on google image search for this board yet lol
04:17 PM gregcnc: the board itself doesn't matter
04:19 PM perry_j1987: i like pictures
04:19 PM perry_j1987: helps when im unfamiliar with a new board before i go hooking things up
04:20 PM gregcnc: the spec sheet is what matters
04:20 PM Tom_L: meh, those are only for those that read em

05:11 PM ziper: the bearing in question https://i.imgur.com/Sn9zHjU.jpg
05:27 PM unterhaus: it would be nice to have example wiring diagrams, probably not worth posting them though
05:33 PM perry_j1987: working on getting spindle speed to display now from the spindle encoder
05:35 PM CaptHindsight: unterhaus: maybe something like this? https://us1.dh-cdn.net/uploads/db5587/original/3X/1/7/170e515a4b3d62e3b151f74f88024e97da400d29.jpeg
05:42 PM perry_j1987: so i doublechecked the wiring from my spindle encoder into the + A, B, Z, 5v and gnd on the encoder plug on the 7i96 got the config made fired up axis and spin the chuck by hand and see no movement on the gladevcp interface
05:42 PM perry_j1987: check hal hm2 7i96.0.encoder.00.input-a and spin it by hand no changes
06:06 PM perry_j1987: multimeter shows it working probinb the pins
06:12 PM Tom_L: invert input?
06:13 PM Tom_L: it's a pin setting
06:16 PM Tom_L: input mode set correct?
06:16 PM Tom_L: P2 manual
06:16 PM perry_j1987: looking
06:17 PM Tom_L: W10 W11 W13
06:17 PM Tom_L: W13 for A signal W11 for B signal
06:17 PM Tom_L: W10 for index channel
06:18 PM Tom_L: differential or single ended
06:18 PM Tom_L: you want single ended
06:18 PM Tom_L: figure out which pin is used for single ended
06:19 PM Tom_L: i'm looking at the wrong pdf... just a sec
06:21 PM JT-Cave: W2, W3 and W4 set the encoder input mode. When W2,W3,and
06:21 PM JT-Cave: W4 are in the right hand position, the encoder input is mode is differential. When W2,W3,
06:21 PM JT-Cave: and W4 are in the left hand position, the encoder input mode is single ended or "TTL".
06:21 PM JT-Cave: 7i96
06:21 PM perry_j1987: assume the ethernet port is to the left in this scenario?
06:22 PM JT-Cave: aye
06:22 PM perry_j1987: comes default set to diferential i take it?
06:22 PM JT-Cave: and words are right side up
06:22 PM JT-Cave: aye
06:22 PM perry_j1987: does board need pwoered off to change these jumpers?
06:23 PM JT-Cave: yes
06:23 PM Tom_L: yeah, same thing i just had the wrong pdf up
06:23 PM JT-Cave: to be safe...
06:23 PM Tom_L: what pin of the differential pair do you use in single ended mode?
06:24 PM JT-Cave: +
06:24 PM unterhaus: CaptHindsight that's nice, do we know who did that?
06:24 PM Tom_L: perry_j1987, ^^
06:24 PM perry_j1987: on the + side
06:24 PM perry_j1987: there we go
06:24 PM perry_j1987: ty
06:24 PM perry_j1987: i see movement heh
06:24 PM JT-Cave: The 7I96 provides a one channel encoder interface with index. This is intended as
06:24 PM JT-Cave: a spindle encoder but can be used for other purposes. The encoder input can be
06:24 PM JT-Cave: programmed for differential or single ended encoders. The encoder interface also provides
06:24 PM JT-Cave: short circuit protected 5V power to the encoder. When used with single ended encoders,
06:24 PM JT-Cave: the ENCA+, ENCB+ and IDX+ signals are wired to the encoder and the ENCA-,ENCB-,
06:24 PM JT-Cave: and IDX- terminals are left unconnected.
06:25 PM JT-Cave: if all else fails RTFM
06:26 PM Tom_L: i keep getting the 7i96 & 7i76 mixed up
06:26 PM JT-Cave: somewhat different lol
06:27 PM * JT-Cave hears some rabbit food being prepared...
06:27 PM perry_j1987: k got the thing moving in right directions, homing, spindle speed displaying now
06:27 PM Tom_L: luckily the encoder inputs were the same :_
06:27 PM JT-Cave: Tom_L, got the s10+ setup today... been turning off crap all day lol
06:27 PM perry_j1987: need to calibrate my pwm to 0-10v board now and then verify steps per mm for the motion
06:28 PM Tom_L: heh
06:28 PM Tom_L: always fun to get rid of the crap they shove down your throat
06:29 PM JT-Cave: a buddy said he saw a video where apple is going to turn off all social media
06:29 PM JT-Cave: due to tracking
06:29 PM JT-Cave: geez I might like a bite of apple now
06:30 PM JT-Cave: looks like dinner is being postponed for a bit...
06:30 PM Tom_L: i use tracking on maps when she travels alone so i can view her location on the pc
06:30 PM Tom_L: handy in that regard
06:30 PM JT-Cave: yep
06:31 PM Tom_L: she got re'routed around the north loop in memphis once... panic mode for her
06:31 PM Tom_L: big wreck on the bridge
06:32 PM JT-Cave: memphis is a cluster fuck for interstate roads lol
06:32 PM JT-Cave: I hate going through it
06:32 PM Tom_L: seems you've had your share of bad luck there too
06:32 PM Tom_L: better than atlanta at rush hour...
06:32 PM JT-Cave: just close calls
06:33 PM Tom_L: where'd your trike break down?
06:33 PM Tom_L: wasn't that memphis?
06:33 PM JT-Cave: New Orleans on the I310 bridge
06:33 PM Tom_L: ahh
06:33 PM JT-Cave: we were leaving Spyders on the Bayou
06:34 PM JT-Cave: Missouri had two days in a row with < 1000 new cases of covid... maybe we are getting out of this mess dunno
06:35 PM Tom_L: i think the numbers are going down here too
06:35 PM JT-Cave: I see more people doing the right thing...
06:35 PM JT-Cave: oh did you see the last workbench photos?
06:36 PM Tom_L: with the back? yes
06:36 PM JT-Cave: yea
06:36 PM JT-Cave: lol I had to install it twice, first time it was on the front...
06:37 PM Tom_L: good you got pics of it now, in a few weeks when you can't find it at least you'll know what to search for under the pile
06:37 PM JT-Cave: lol
06:38 PM CaptHindsight: unterhaus: https://forum.v1engineering.com/t/lowrider2-plasma-build/13939
06:40 PM unterhaus: thanks, took me 15 minutes to realize the stuff at the top center is limit switches
06:42 PM unterhaus: would be nice if the lines were thicker on some of the wiring. I like that he didn't draw all the steppers
06:43 PM Tom_L: just get thicker glasses :)
06:44 PM unterhaus: my glasses are maxxed out
06:44 PM JT-Cave: rotflmao
06:44 PM unterhaus: I clicked on it and it got a lot bigger
06:46 PM CaptHindsight: unterhaus: on the LCNC forums the same avatar is used by AgentWD40 , might be the same person
06:55 PM perry_j1987: there we go
06:55 PM perry_j1987: spindle calibrated heh
06:55 PM perry_j1987: feels good
07:08 PM CaptHindsight: anything new in 4-5 axis CAM?
07:09 PM CaptHindsight: what do you have to do for Fusion360 if you want 4-5 axis? Get a full subscription?
07:09 PM Tom_L: probably
07:10 PM CaptHindsight: does Fusion360 use PowerMill?
07:10 PM CaptHindsight: or is that yet another CAM app by autodeck?
07:10 PM Tom_L: dunno
07:10 PM CaptHindsight: https://www.autodesk.com/products/powermill/features
07:10 PM Tom_L: pretty sure they use catia at my kids work
07:10 PM Tom_L: but you gotta get the cam separate
07:11 PM Tom_L: or at least the post
07:11 PM Tom_L: for a particular machine
07:11 PM CaptHindsight: my machine is custom
07:12 PM Tom_L: http://www.nccs.com/
07:12 PM Tom_L: somebody around here was looking at that iirc
07:13 PM Tom_L: mastercam probably does 5
07:13 PM Tom_L: it's fairly popular
07:14 PM CaptHindsight: yeah, mastecam is not inexpensive
07:14 PM Tom_L: none of the good ones are
07:14 PM CaptHindsight: and again requires a custom post for a custom machine
07:14 PM CaptHindsight: are there any bad cheap 4-5 axis CAM apps?
07:15 PM Tom_L: that was a selling point for smartcam for me years ago.. the post could be customized easy
07:15 PM Tom_L: i dunno
07:16 PM CaptHindsight: most also require Winders
07:17 PM Tom_L: https://bobcad.com/products/bobcam-5-axis-cad-cam-pro/
07:17 PM Tom_L: dunno anything about bobcad now
07:18 PM Tom_L: i'd say for those around here that don't use catia, use mastercam

07:23 PM CaptHindsight: HSMWorks post processors are written in Javascript
07:24 PM CaptHindsight: I talked to mastecam last year about custom mods
07:24 PM CaptHindsight: the have a big API
07:29 PM CaptHindsight: 300MB download, Visual Studio and C++
07:33 PM W1N9Zr0: fusion already has a linuxcnc compatible 5 axis post, the PocketNC one
07:34 PM W1N9Zr0: pocketnc runs machinekit, and they have a custom code for switching tool center point control. the post works with TCPC and without
07:40 PM CaptHindsight: W1N9Zr0: yes getting close since it supports LCNC but not my type of 5 axis machine
07:41 PM CaptHindsight: last year i think they offered the 5-axis CAM for use with PocketNC for ~$200/year
07:50 PM W1N9Zr0: don't think fusion CAM makes use of UVW. just tried drilling at an angle, and it uses G1 diagonal moves instead of drilling cycles
07:52 PM W1N9Zr0: you could rewrite the post to make use of it, but what would you use W for besides drilling cycles?
07:52 PM CaptHindsight: my machine uses no cutting tools
07:53 PM W1N9Zr0: why is your post talking about a horizontal boring mill then?
07:53 PM CaptHindsight: the post had 0 replies
07:57 PM CaptHindsight: autodesk at least has some LinuxCNC support
07:58 PM CaptHindsight: you mention Linux to many vendors and they blow a basket and think you want their software for free
07:58 PM CaptHindsight: vs a paid version that just runs on Linux
07:59 PM ziper: is it a bad idea to weld a little thing on a bearing cup so that I can pull it?
08:02 PM Tom_L: probably
08:03 PM Tom_L: especially if you're trying to save it
08:03 PM roycroft: a good rule of thumb is to be very careful if you want to use the words "weld" and "bearining" in the same sentence
08:03 PM roycroft: bearing, rather
08:04 PM roycroft: they almost always do not belong in close proximity to each other
08:05 PM CaptHindsight: ziper: how is the bearing captured that you are even considering doing this?
08:06 PM ziper: i'm not trying to save it, it is trashed and i have a replacement cup
08:06 PM roycroft: is it just my consistent bad timing, or is sourceforge down more than it's up these days?
08:06 PM Tom_L: poor design if there isn't a way to remove it
08:06 PM ziper: its pressed into a nearly blind hole
08:06 PM ziper: https://i.imgur.com/Sn9zHjU.jpg
08:07 PM roycroft: if you are going to trash it, i'd consider drilling a couple small holes in the bearing cup and inserting some screws in them, then pulling on the screws
08:07 PM Tom_L: or splitting the race
08:08 PM roycroft: yeah, that would work too
08:08 PM ziper: splitting the race?
08:09 PM Tom_L: or
08:09 PM Tom_L: is it possible to drill 2 holes on the backside and use a small punch to punch it out?
08:09 PM Tom_L: just small holes
08:11 PM CaptHindsight: it's a hardened race
08:13 PM W1N9Zr0: a variation on this might work: How to Remove a Pilot Bearing with Bread https://www.youtube.com/watch?v=00OlG5E8vLk
08:14 PM Tom_L: CaptHindsight, don't drill the race rather 2 holes on the bottom side to punch from the bottom
08:14 PM Tom_L: the housing
08:16 PM CaptHindsight: ziper: is that a gearbox behind it?
08:17 PM CaptHindsight: looks like there is a gap behind the race on the op of the pic but clearance on the bottom
08:17 PM ziper: thats the headstock
08:43 PM unterhaus: when I was trying to destroy bearings, I found that drilling holes in them wasn't really that difficult
08:44 PM unterhaus: using a bridgeport though
09:00 PM gregcnc: what is it and how do others pull that bearing?
09:00 PM perry_j1987: use a magnet
09:00 PM perry_j1987: pull it right out :)
09:00 PM perry_j1987: one from ACME like the coyote always uses
09:03 PM roycroft: wile e. coyote would use some tnt to get that bearing out
09:03 PM roycroft: or would drop an anvil on it from a high above cliff
09:03 PM perry_j1987: that'd work too i suppose
09:03 PM perry_j1987: many ways to skin this cat heh
09:03 PM roycroft: animaniacs would also drop an anvil on it
09:10 PM unterhaus: I think the bread/grease trick would work, just gotta plug that hole
09:22 PM skunkworks: ziper: weld a bead around the bearing race.. it will fall out
09:25 PM CaptHindsight: I wonder if bread was ever tried for disc brakes?
09:27 PM roycroft: we're having quite the wind storm all of a sudden
09:27 PM unterhaus: in this case the bread trick would be a lot easier with access to a working lathe
09:29 PM ziper: this is the unworking lathe, unfortunately
