[05:29:16] <miss0r> I have a shaft with 44 splines on each end. They are triangular splines. pointy... I turned down the chamfer on the end and scanned it to get a clean picture. https://imgur.com Big OD is 23.67mm small OD is 22.48mm. but with all the rounded valeys and peaks I am having a hard time getting a collect reading. Can any of you guys help me determin what angles this is made with?
[05:29:26] <miss0r> or is there a special form factor I need to consider?
[05:29:37] <miss0r> any help at all would be very helpfull
[05:30:01] <XXCoder> looking
[05:31:05] <XXCoder> note i dont know those, but i onder if you could reverse engineer it using cad
[05:31:19] <XXCoder> include a ruler in it, and use it to scale correctlyu
[05:31:45] <miss0r> I have an 'on screen' protractor. but the resolution I can scan it with is not great enough for a proper reading
[05:32:07] <miss0r> I would assume the have the same issue with cad
[05:32:12] <XXCoder> hmm cant do higher resolution?
[05:32:51] <miss0r> 2 secs - investigating
[05:34:30] <miss0r> it seems I can double the resolution
[05:34:38] <miss0r> i'll add a ruler to the photo, 2 secs
[05:35:17] <syyl> high probability that it is 90°
[05:35:36] <miss0r> syyl: Indeed. but I can't seem to make the math fit
[05:35:46] <miss0r> which is why I am in here crying :]
[05:35:57] <syyl> meh ;)
[05:36:09] <syyl> do you want to make a scientific approach?
[05:36:15] <syyl> or just cut the damn profile? ;)
[05:36:38] <miss0r> well. I want to cut the damn profile, but I want to make damn sure it is an excellent fit
[05:36:52] <syyl> da a over-pin measurement
[05:37:00] <syyl> (thats the scientific approach)
[05:37:42] <miss0r> higher res, with ruler in there: https://imgur.com
[05:37:51] <miss0r> syyl: can you be more specific? :D
[05:38:12] <miss0r> also; I think my smallest pin is 3mm
[05:38:14] <syyl> drop a small diameter pin in two exactly oposing spline-grooves
[05:38:22] <miss0r> :D
[05:38:24] <syyl> and do a measurement with a micrometer
[05:38:34] <syyl> and then use that in cad to create the real profile
[05:38:37] <syyl> or do what i do
[05:38:47] <miss0r> alright. What can I use that measurement for?
[05:38:58] <syyl> got parametric cad?
[05:39:10] <miss0r> I have no idea what that means :D I use mastercam
[05:39:19] <syyl> let the pin diameter and distance drive the sketch for the spline
[05:39:26] <jthornton> morning
[05:39:44] <miss0r> jthornton: morning
[05:39:55] <miss0r> syyl: I can't help but feel I am missing something for that to work
[05:40:23] <syyl> you only need the number of teeth, the angle of the spline and the pindiameter/distance
[05:40:35] <syyl> and the OD of the shaft
[05:40:36] <miss0r> problem is; I don't know the angle of the teeth
[05:40:50] <miss0r> if I had that, I would just cut the damn splines :D
[05:40:53] <syyl> thats 90
[05:41:00] <syyl> just measured it
[05:41:21] <miss0r> with what, if you don't mind me asking?
[05:41:31] <miss0r> I can't seem to get a proper reading with my protractor software
[05:41:32] <syyl> haha
[05:41:40] <syyl> with a protractor
[05:41:43] <syyl> against my screen
[05:41:50] <syyl> as you do
[05:42:02] <syyl> ah not called protractor
[05:42:05] <syyl> drafting triangle?
[05:42:18] <miss0r> basically the same thing.
[05:42:33] <miss0r> So, what you are telling me is: it is absolutly not 86degrees?
[05:42:36] <miss0r> (example)
[05:43:13] <syyl> nobody in his right mind would make something with such a stupid angle
[05:43:14] <syyl> plus
[05:43:19] <miss0r> this splines has to handle a pretty sizeable amount of torque, so I would realy like for it to be seated probably
[05:43:21] <syyl> there is a standard for spline drive profile
[05:43:47] <miss0r> with refrence to "nobody in their right mind"; this is a '72 land rover...
[05:43:56] <syyl> oh dang it
[05:44:01] <miss0r> yeah :]
[05:44:03] <syyl> good luck, youre on your own.
[05:44:11] <miss0r> xD thanks
[05:44:18] <syyl> you know what a real captain does?
[05:44:27] <syyl> leave the sinking ship before anyone else notices.
[05:44:34] <miss0r> hehe
[05:45:02] <syyl> well, i have to eat my words
[05:45:10] <syyl> the iso standard spline drive profile is 60°
[05:45:11] <syyl> haha
[05:45:12] * miss0r perks up
[05:45:15] <miss0r> yeah
[05:45:33] <miss0r> nothing standard about this. When the leyland factory workers were not busy getting high, they were on strike
[05:46:02] <syyl> all i know about british leyland is what i know from topgear ;)
[05:46:22] <miss0r> you didn't miss much :D
[05:46:54] <miss0r> lets just say; clarksson did not exaggerate
[05:48:42] <miss0r> the problem is, this spline is so tiny, it is hard to do a proper measurement. and I don't have one of those visual comparetors...
[05:51:37] <miss0r> i'll do a testpeice with a 90degree cut and try to see how well that fits with the mating part
[05:52:15] <syyl> :)
[05:52:31] <syyl> do you need to make the male of female part?
[05:53:18] <miss0r> I need to make a male part
[05:53:29] <miss0r> the one I have scanned
[05:53:39] <syyl> ah ok
[05:53:42] <syyl> thats not that hard
[05:53:51] <syyl> are you going to use a v-cutter?
[05:54:16] <miss0r> I have a 90degree included angle "slitting saw" or disc mill - whatever you call it
[05:54:25] <syyl> or use a normal straight endmill
[05:54:33] <syyl> and put it at the edge of the part
[05:54:35] <miss0r> yeah.. that could work as well
[05:54:45] <syyl> i did a woodchiper spline that way ;)
[05:55:15] <miss0r> I think that is the way I will go. the diameter on my "slitting saw" is a bit too big, so I would have to rething the shoulder design.
[05:55:30] <miss0r> with a regular endmill, I can just go up against that shoulder.
[05:55:43] <miss0r> (it has a radius to it, so it would fit nicely with an endmill)
[05:55:54] <syyl> :)
[05:56:23] <Loetmichel> missor: you mean like that? -> http://www.cyrom.org
[05:56:32] <Loetmichel> http://www.cyrom.org
[05:56:34] <Loetmichel> :-)
[05:57:22] * Loetmichel used one just like that last week to saw off 10mm of an aluminium (7075) block... was behind the gantry side block all the time...
[05:57:25] <Loetmichel> :-)
[05:58:30] <miss0r> Loetmichel: This one: https://imgur.com

[06:10:57] <Tom_L> morning
[06:14:40] <Loetmichel> miss0r:ah, the good professional ones
[06:15:34] * Loetmichel was a bit wary of the selfbiolt one because that sawblade should only have 8krpm, not 24krpm and the blade only holds on a 0,2mm step on the far side ;)
[06:16:09] <miss0r> :D sounds dangerous
[06:16:31] <Loetmichel> seen the pics?
[06:16:44] <SpeedEvil> It's only dangerous if it goes wrong.
[06:17:05] <Loetmichel> SpeedEvil: the part was also only mounted to the bed with CA glue ;)
[06:17:13] <Loetmichel> so overheat: VERY bad idea ;)
[06:18:30] -!- gloops has joined #linuxcnc
[06:18:39] <miss0r> Loetmichel: Yeah, I saw the pictures. Doesn't look too bad. But the speeds you are talking about, I would not want to be anywhere near that
[06:18:51] <Loetmichel> indeed
[06:19:18] * miss0r is doing some very very needed shop cleaning
[06:19:41] <Loetmichel> problem is that all that holds the blade on the arbor(?) is a 0.2 by 0.2mm lip on that steel bolt i turned down into the arbor.
[06:20:31] <Loetmichel> (is arbor correct for the pin that holds the blade and is inserted into the ER11?)
[06:20:41] <miss0r> on the "underside" ?
[06:20:45] <Loetmichel> yes
[06:21:08] <miss0r> heh... if it does a small colision, you will have a flying saucer on your hands :D
[06:21:22] <Loetmichel> i wanted it to be able to cut down to surface of the table
[06:21:35] <Loetmichel> so the lip had to be smaller than the tooth overhang
[06:22:01] <Loetmichel> not a flying saucer... a flying sawblade at 24krpm
[06:22:11] <Loetmichel> ... halflife2 anyone?
[06:22:22] <Loetmichel> :-)
[06:22:34] <syyl> we dont go to ravenholm.
[06:22:50] <Loetmichel> hihi
[06:22:55] <Loetmichel> exactly
[06:23:20] <miss0r> Man. That brings back mamories
[06:23:42] <miss0r> half life 3 is confirmed, by the way
[06:23:59] <Loetmichel> http://www.cyrom.org <- thats how i used the old one...
[06:24:14] <Loetmichel> the new one i made last week was a bit "safer"
[06:24:17] <miss0r> but since halflife two, I have bought a house, gotten married & had two children... I just don't have the time to play that much anymore :)
[06:28:07] * Loetmichel plays Elite Dangerous and lately X4
[06:28:24] <Loetmichel> i have about 4000 hours in E:D in the last 4 years... ;9
[06:28:37] <Loetmichel> so much for marriage. lucky me: no children
[06:31:22] <miss0r> yeah, lucky you
[06:31:53] <miss0r> My oldest son is 3 years old. Last night I was one uttered latin word from calling an exorcist...
[06:32:07] <miss0r> but they are alright most of the time

[06:36:57] <Loetmichel> miss0r: the new slotting saw i used on AL last week: http://www.cyrom.org
[06:37:34] <miss0r> that looks a smidge better
[06:37:36] <miss0r> welded in?
[06:37:40] <Loetmichel> nope
[06:37:48] <Loetmichel> just an M8 bolt turned dwon
[06:37:50] <Loetmichel> down
[06:37:58] <miss0r> in that case: eek!
[06:37:59] <miss0r> :)
[06:38:47] <Loetmichel> but this time a lot more "flesh" on the outside
[06:38:48] <Loetmichel> :-)
[06:39:21] <miss0r> Why not get proper ones?
[06:40:53] <Loetmichel> that blade is for a small circular saw... i just needed a tool to get the alu shortended down
[06:41:12] <Loetmichel> so i had blades... and M8 bolts... and a lathe... you get the idea?
[06:44:51] <Loetmichel> "you are only really a hobby machinist if you catch yourself making a tool to make a jig to hold a part for a machine to make a part the pourpose you have long forgotten by that time" ;)
[06:45:59] <miss0r> hehehe yeah
[06:46:16] <miss0r> well, I turned this hobby of mine into a full time job :]
[06:46:22] <Loetmichel> same here ;)
[06:46:46] <miss0r> which means; I am now cleaning my shop & being annoyed noone is paying me to do it :D
[06:47:29] <Loetmichel> when we have customers here at the company and they see me doing "metal origami" by hand they are always in total disbelief
[06:47:42] <Loetmichel> .. and all because the company has no bending brake ;)
[06:47:49] <miss0r> hehe
[06:48:00] <miss0r> I just miss having coworkers to blame for leaving coffee cups around
[06:48:07] <miss0r> noone here but me.. hehe
[06:48:10] <SpeedEvil> Get a cat.
[06:48:19] <SpeedEvil> Blame it for everything.
[06:48:30] <miss0r> I had a cat. it got eaten by the other cats 'round here
[06:48:46] <miss0r> alot of "wild" cats roaming the area
[06:49:00] <Loetmichel> http://www.cyrom.org <- that kind of stuff.. and yes, i bend it by hand
[06:49:08] <miss0r> they are domestic cats, just with no owner. So, they eat whatever they can find - enter my cat
[06:49:10] <SpeedEvil> miss0r: next project - cat mecha suit.
[06:49:31] <Loetmichel> only tool is the steel bar with the slot in it below
[06:49:35] <miss0r> Loetmichel: I understand why they were in disbelief :)
[06:49:51] <SpeedEvil> Loetmichel: never underestimate the power of a slot and a hammer.
[06:49:56] <Loetmichel> http://www.cyrom.org <- like that
[06:50:08] <Loetmichel> SpeedEvil: no hammer
[06:50:12] <Loetmichel> just hands ;)
[06:50:17] <miss0r> SpeedEvil: hehe. Another problem; theres ALOT and I mean ALOT of those small tick's in the are. and they are dragged in with the cat and jumps us humans
[06:50:19] <SpeedEvil> I missed the v-grooves.
[06:50:22] <SpeedEvil> that is cheating.
[06:50:30] <miss0r> In my area they are know to have some nasty sicknesses with'em
[06:50:57] <Loetmichel> SpeedEvil: not V-grooves. 2mm wide rectanglular slots
[06:51:08] <Loetmichel> makes a slightly rounded corner on the outside
[06:51:11] <Loetmichel> looks better
[06:52:52] <Loetmichel> miss0r: thats why domestic cats and dogs here have "flea neck bands"
[06:52:57] <Loetmichel> they work for ticks, too
[06:55:02] <Loetmichel> miss0r: it looks a bit like a "slight of hand" trick when you make series of aluminium boxes like these: http://www.cyrom.org
[06:55:28] <Loetmichel> or these brass shielding boxes: http://www.cyrom.org
[06:55:58] <Loetmichel> ... the file is just to get the soldered corners nice and smooth
[06:57:03] <Loetmichel> http://www.cyrom.org <- like that
[06:58:24] <Loetmichel> you know, like those pizza carton folders in those youtube videos ;)
[06:58:35] <SpeedEvil> Loetmichel: meanwhile here I am with plywood and wood glue. :)
[06:59:13] * SpeedEvil is waiting for the fan for his new 0-22V or so 5A PSU.

[07:07:30] <Loetmichel> miss0r: i dont see why they are in disbelief though. its 1.5mm aluminum, slottd to 0,75m or 1mm brass slotted to 0,5mm. it bends with virtually no resistance at all
[07:08:19] <Loetmichel> only tricky part are small flaps that dont want to bend at the right place... hence the second slotted aluminium tool to use as a "come along" ;)
[07:08:42] <Loetmichel> [12:49] <Loetmichel> http://www.cyrom.org <- like that
[07:08:44] <SpeedEvil> Loetmichel: 1/thickness^3 is a powerful term.
[07:08:47] <miss0r> indeed :]
[07:09:23] <Loetmichel> SpeedEvil: indeed ;)
[07:09:49] <Loetmichel> i do the same with 4mm alu though... needs a bit more muscle, but works just the same ;)
[07:10:46] <miss0r> bah. i just remembered I have two ISO 50 spindles to regrind/dress tomorrow. I better prepare the equipment
[07:11:12] <SpeedEvil> miss0r: feeling blue about it?
[07:11:32] <miss0r> pun intended, I presume :)
[07:11:45] <miss0r> Nah. I just forgot about it, and its been a while since I used the gear.
[07:11:53] <miss0r> So, I have a few hours of preparing ahead of me
[07:11:58] <miss0r> and I wanted to take an early day today
[07:17:58] <Loetmichel> btw: next 19" 2U front panel on the mill... already running 4 hours, no end in sight ;)
[07:18:31] <Loetmichel> maybe i shouldnt do 8mm thick alu with tons of pockets on a CNC 6040 router with a 6mm two flute bit...
[07:18:57] <Loetmichel> ... at least its a new one, MUUUCH less heat in the workpiece than the last time with the dull HSS one ;)

[12:54:28] <CNC_Brian> Tried blacklisting parport_pc in /etc/modprode.d/ but its still loaded
[12:54:38] <CNC_Brian> Any suggestions
[12:57:10] <adamj12b> jthornton: You wouldn't happen to know how to activate the index-enable signal when orient is called would you? Its a bidirectional signal and i cannot figure out how to tap into it without breaking synchronized motion.
[13:00:48] <JT-Shop> I've never messed with orient sorry
[13:01:44] -!- P1ersson has joined #linuxcnc
[13:08:02] <pcw_home> The fact that index-enable is bi-directional means you need a component with a bidirectional pin to connect to it
[13:08:30] <pcw_home> This exists: tristate_bit
[13:17:52] <adamj12b> pcw_home: Thank you! That looks like it will do the job. I have orient working but have to set index-enable manually to reset the encoder.

[13:19:57] <adamj12b> pcw_home: Second question, what is the update rate on the spindle analog output of a 7i76e? Im sure its no where as fast as the 7i77 that is in the machine, which would explain what I cant get the error as low as I would like on the bench.
[13:31:39] <pcw_home> 7I77 outputs have about a 2 KHz bandwidth, 7I76 analog out is closer to 200Hz
[13:32:22] -!- KimK has joined #linuxcnc
[13:32:58] <pcw_home> also analog out + separate direction has issues if you reverse (as might happen at close to 0 speed)
[13:34:58] <adamj12b> Im not suing the direction output on the 7i76. Just EN and analog to mimic the 7i77 then I use outputs 14 for FWD and 15 for REV.
[13:35:37] <pcw_home> same issue though, if PID sets direction
[13:36:19] -!- HP_ has joined #linuxcnc
[13:36:45] <pcw_home> (lack of synchronism between speed and direction signals in both 7I76 and drive)
[13:36:51] -!- HP_ has parted #linuxcnc
[13:37:30] -!- gloops has joined #linuxcnc
[13:38:58] <adamj12b> Im trying to understand. Are you saying that by the time the vfd switches direction the pid thinks that happened some time ago?
[13:39:39] <Tom_L> likely so
[13:40:38] <adamj12b> on my mill, using the 7i77 to command the VFD, I can lock the spindle my issuing an S200 command and switching directions every 50mS. This is using a second acceleration map of 0.2sec/1000hZ.
[13:40:46] <adamj12b> by*
[13:41:33] <adamj12b> BUT, that is not using pid for speed control. just the default FF0 = 1
[13:46:04] <pcw_home> you should be able to do the same with the 7I76 (fixed analog out + reversing directions)
[13:47:44] -!- ve7it has joined #linuxcnc

[14:47:46] <fragalot> Jymmm: that is indeed quite neat if you would want to start doing on-site stuff
[14:55:15] <roycroft> the problem with that is that you can only use it once
[14:55:38] <roycroft> when you deflate it, the overspray that stuck to the walls of the booth will crack and peel off
[14:55:56] <roycroft> and next time you inflate it you'll have a booth full of crap that will get all over your job when you start shooting paint
[15:02:39] -!- gloops has joined #linuxcnc
[15:07:53] <fragalot> roycroft: that is what the leafblower is for
[15:08:37] <roycroft> i don't have anything remotely approaching a proper paint booth environment
[15:09:04] <fragalot> same
[15:09:14] <roycroft> i'm resigned to knowing i'll be doing a lot of sanding/buffing and shooting extra coats to get rid of the inevitable crap that gets on the paint job
[15:09:14] <fragalot> I also don't have the space for that inflatable thing, lol
[15:09:56] <roycroft> i have a nice side tent for my vw bus
[15:10:15] <roycroft> it has an external skeleton - the tent fabric hangs from the poles
[15:10:39] <roycroft> i made a "spray booth" out of 6 mil plastic that i hang from that frame when i need to do spray painting
[15:11:05] <roycroft> and it works decently, other than the overspray problem
[15:11:27] <roycroft> most of the overspray lands on the floor, and i do line the floor with paper before starting to spray
[15:11:38] <roycroft> then i carefully fold up and toss the paper at the end of the job
[15:11:56] <roycroft> that helps a lot, but i still get little bits of flaked paint that floats around when i start spraying
[15:12:40] <roycroft> not to mention that it's not ventilated, and even with a good respirator, i can't spray for very long at a go
[15:12:47] <roycroft> i should get a decent fresh air respirator
[15:14:11] <gloops> have to be careful if using 2k paints or laquers, only takes a few hours of breathing that crap for permanent damage
[15:15:50] <roycroft> yes, some of it can be very nasty
[15:15:57] <roycroft> dupont imron is especially nasty
[15:16:04] <roycroft> fabulous paint though

[15:24:40] * roycroft doesn't recall discussing making anything recently
[15:25:08] <Jymmm> fragalot: yeah =)

[15:26:25] <roycroft> oh, no
[15:26:36] <roycroft> we were discussing inflatable paint booths
[15:26:49] <Jymmm> gloops: Read the logs starting at 01:40 PM
[15:27:14] <roycroft> i am making some cabinets for my lathe at the moment, howeer
[15:27:28] <roycroft> i built an open stand for the lathe, with the intention of adding some drawer units to it later
[15:27:33] <roycroft> later has finally arrived
[15:27:37] <gloops> thanks Jymmm - hes just said what it was about though
[15:27:50] <roycroft> but i'm using a paint roller for them
[15:27:56] * Jymmm is trying to figure out the best way to cut a 3" hole in the top of propane tanks
[15:28:13] <roycroft> i did spray the stand in my vw tent spray booth
[15:28:30] <roycroft> jymmm: the best way is without explosions
[15:29:01] <Jymmm> roycroft: They are all been thru the fire and the valves have been removed since Decemeber
[15:29:17] <roycroft> oh, they're quite unlikely to explode then
[15:29:49] <Jymmm> If they didn't explode in forest fire, they aren't going to now.
[15:29:51] <roycroft> use a hole saw
[15:30:05] <Jymmm> What kind/type of hole saw you think?
[15:30:07] <roycroft> stuff a plug in the valve hole and use that for the pilot drill
[15:30:27] <roycroft> i don't think you'd need carbide for a propane tank
[15:30:45] <roycroft> although a carbide one would last longer, assuming you have several to do
[15:31:06] <Jymmm> at least three,
[15:31:28] <roycroft> carbide hole saws are not expensive
[15:31:29] <Jymmm> Going to thry and turn them into mini pellet typs stoves
[15:31:40] <roycroft> but the're normally not stocked at big box home improvement stores
[15:31:53] <Jymmm> or chimenia's (sp?)
[15:32:16] <roycroft> for only three tanks, a standard bi-metal hole saw would probably suffice
[15:32:37] <roycroft> i'd try to use a drill press for it
[15:32:52] <roycroft> hand holding 3" hole saw while drilling through steel is not fun
[15:33:35] -!- extor has quit [Remote host closed the connection]
[15:33:36] * roycroft has done that to drill several 3" holes through 0.120" steel, and wished he had a mag drill the whole time
[15:33:52] <Jymmm> Yeah, and no side handle on the drill either =(
[15:33:54] -!- extor has joined #linuxcnc

[16:38:03] <Tom_L> ~150rpm maybe?
[16:38:10] <JT-Shop> we used to have to drill holes in some crappy places lol
[16:38:16] <JT-Shop> something like that
[16:41:22] <Tom_L> i wish i had the ctk for mine so i could make decent dialog boxes for the macros
[16:41:47] <JT-Shop> ctk?
[16:42:07] <Tom_L> i think that's what it was called..
[16:42:31] <roycroft> that's one of my three major problems with fusion360
[16:42:47] <roycroft> it's free for now, for limited use, but almost guaranteed to be not free in the long term
[16:43:16] <roycroft> the other two problems being that it requires calling home and storing things in the cloud, and using a proprietary file format
[16:43:32] <roycroft> the latter would not be so big an issue if it weren't for the first two
[16:44:31] <Tom_L> JT-Shop similar to the toolkit you used to make your screens
[16:46:16] <gloops> i think you can renew the amateur license? so long as earning under 100k, tell them your backs gone you arent working
[16:46:17] <Tom_L> Smartcam Customization Toolkit

[17:06:13] <jthornton> I use my mill G code generator for all my hole ops
[17:06:25] <Tom_L> yeah i remember that
[17:07:06] <jthornton> spot, drill, counter sink, tap, and more I think lol
[17:08:00] <Tom_L> do you rigid tap?
[17:08:06] <jthornton> yea
[17:08:21] <jthornton> I could program it to do thread milling...
[17:08:27] <Tom_L> i got my cam post to do that pretty well
[17:08:40] <Tom_L> now the macro does the thread milling as a helix
[17:09:37] <Tom_L> i think i want to change the peck cycle from the G83 to G73 though
[17:09:47] <Tom_L> at least try it
[17:11:38] <jthornton> G74 Left-hand Tapping Cycle, Dwell
[17:12:05] <jthornton> I wonder what they mean by left handed?
[17:12:43] <Tom_L> cool, i just tried the macro with TPI as a negative and it creates it from the top down
[17:15:03] <Tom_L> i need to revese the Z leadin move for it though

[17:19:09] <Tom_L> don't understand why you would have dwell on a tapping cycle though
[17:20:12] <Tom_L> maybe to create a relief pocket on a lathe?

[18:00:13] <Tom_L> then explain the dwell to me ?

[18:01:04] <Tom_L> hah
[18:01:22] <Tom_L> the one was added in 2.8.. who added it?
[18:01:35] <JT-Shop> dunno
