08:31 PM Tom_L: i had some brass cutoff chunks in the drawer i decided to mess with
08:32 PM rue_bed2: nice
08:33 PM rue_bed2: the cat, is outside, in the rain, crying about how much he dislikes it
08:33 PM rue_bed2: the window for him to get in is open
08:33 PM rue_bed2: so is the kitchen door
08:33 PM Tom_L: i gotta figure out the major, minor diameters etc as i go
08:36 PM Tom_L: cats amaze me
08:47 PM rue_bed2: he came in, but like, wtf cat?
08:49 PM rue_bed2: I need to write a quick little NC for leveling the sacraficial wood on the cnc
08:49 PM rue_bed2: g01..
08:50 PM rue_bed2: g01 ....
08:50 PM rue_bed2: g01 ....
08:50 PM rue_bed2: its a 3/4" router bit
08:50 PM rue_bed2: the fly cutter isn't balanced
09:03 PM Tom_L: what rectangle size?
09:03 PM Tom_L: stepped over how far?
09:03 PM rue_mohr: yes, I need to know that
09:03 PM Tom_L: what size cutter?
09:03 PM Tom_L: i can whip it out pretty quick
09:03 PM rue_mohr: heh
09:03 PM rue_mohr: I cant whip that one...
09:03 PM Tom_L: sure you can
09:04 PM Tom_L: G01 X 6.0 F5
09:04 PM Tom_L: G01 Y .5
09:04 PM Tom_L: G01 X -6.0
09:05 PM Tom_L: G01 Y .5
09:05 PM Tom_L: G01 X 6.0
09:05 PM Tom_L: with a -z above that and +z below it
09:06 PM Tom_L: 3/4 bit... you could step over a bit more if you want
09:06 PM Tom_L: how big is the table
09:06 PM Tom_L: G01 Y .700
09:06 PM Tom_L: just go past center a bit or you'll have half moons on the ends
09:07 PM Tom_L: here i got one for you
09:07 PM Tom_L: but you'll have to change the stepover from 2"
09:08 PM Tom_L: and add a few more repeats
09:08 PM rue_shop1: oh right!

09:09 PM rue_shop1: the bit is 15/16
09:10 PM Tom_L: i don't have a cutter set up that wide other than my flycutters
09:10 PM Tom_L: where's zero at?
09:13 PM Tom_L: how many flutes is the cutter?
09:16 PM rue_shop1: zero can be lower left
09:16 PM rue_shop1: 2 flutes
09:17 PM Tom_L: ok i'm about done
09:17 PM rue_shop1: its wood
09:17 PM rue_shop1: so it can be a moderatly agressive cut speed and I'll dial the motor all the way up
09:17 PM Tom_L: starting with a .375 overlap for your 6.5 x 4
09:17 PM Tom_L: so the cutter clears it all
09:17 PM Tom_L: you can fiddle with the feed
09:17 PM Tom_L: i did it slow
09:18 PM rue_shop1: I'm just remounting the wood and setting up the bit
09:18 PM Tom_L: you'll have to adjust the z depth
09:18 PM Tom_L: i dunno how much you want off
09:21 PM rue_shop1: oh,
09:21 PM rue_shop1: cant overcut on the X, I have clamps in the way

09:22 PM Tom_L: i might have to shorten X then
09:22 PM Tom_L: or you can
09:23 PM rue_shop1: kinda short with a cutter that big eh?
09:23 PM Tom_L: z will need to be set
09:23 PM Tom_L: that's just basically the x y path
09:23 PM Tom_L: i told you you could hand write it
09:23 PM rue_shop1: hah did you just do that by hand?
09:24 PM Tom_L: x y o is lower left
09:24 PM Tom_L: no
09:24 PM Tom_L: i could have about as quick
09:24 PM Tom_L: i did a pocket cutout so it was quick
09:24 PM Tom_L: test it first
09:24 PM rue_shop1: ok thats for a 3/4" bit?
09:24 PM Tom_L: if it's wroing i can fix it
09:24 PM Tom_L: yes
09:25 PM rue_shop1: mine is 15/16.. that'll over cut by sone eh?
09:25 PM Tom_L: yeah
09:25 PM Tom_L: and i extended the bounds by .375 on all 4 sides so it would cut it all
09:25 PM Tom_L: you will want to change that for the clamps
09:25 PM Tom_L: i can't see them
09:26 PM rue_shop1: k
09:26 PM Tom_L: it's easy to change if you need
09:26 PM Tom_L: inch not metric
09:26 PM rue_shop1: yea, just moddin in
09:26 PM rue_shop1: modding it
09:26 PM Tom_L: right, i figured you could
09:27 PM Tom_L: once you got the general path
09:27 PM rue_shop1: ok I'll step this...
09:28 PM Tom_L: it will cut to the center of the cutter so 6.5 will be more by .375
09:28 PM Tom_L: since it's a .750 cutter
09:28 PM Tom_L: done because you want a flat on the ends, not half moons leftover
09:29 PM Tom_L: i could spiral it if you want a prettier pattern :)
09:32 PM Tom_L: and you could change the tool number to a lower one. i'm getting quite a tool inventory in the cad
09:32 PM Tom_L: just so H matches it
09:33 PM Tom_L: although GRBL ignores H
09:36 PM rue_shop1: feed rate of 9 would have been ok
09:36 PM rue_shop1: it didn't like H
09:36 PM Tom_L: yeah just get rid of it
09:36 PM rue_shop1: spiral, but harder to adjust
09:36 PM Tom_L: it doesn't support tool offsets
09:37 PM Tom_L: linear, zigzag or spiral
09:37 PM Tom_L: i didn't like the way linear generated so i zigzag'd
09:38 PM Tom_L: i don't know your machine so i so slow on the feeds
09:41 PM Tom_itx: here's spiral for the heck of it. (center out)

09:43 PM rue_mohr: short video, mind it flip you a bird
09:43 PM rue_mohr: you had an issue last time didn't you?
09:44 PM Tom_L: ?
09:44 PM Tom_L: heh
09:44 PM Tom_L: that would drive me nuts
09:44 PM Tom_L: so it's cutting ok?
09:44 PM rue_mohr: well I should go watch it
09:44 PM rue_mohr: I think 9 would have been good
09:45 PM Tom_L: bump it up
09:45 PM rue_mohr: I usually do it by hand with the pendant
09:45 PM Tom_L: dial the knob up to 11 dammit !!!
09:45 PM rue_mohr: cant, I accidently hit run and it cached almost the whole program
09:45 PM Tom_L: you should use a flycutter on that
09:46 PM rue_mohr: its not counterbalanced
09:46 PM Tom_L: mine isn't either
09:46 PM Tom_L: i run it around 2krpm
09:46 PM Tom_L: it's fine
09:46 PM Tom_L: sometimes i stretch the cutter out further than i should too
09:47 PM Tom_L: did you make those thumb knobs for the clamps?
09:47 PM Tom_L: mine came with regular nuts
09:49 PM Tom_L: hah. i forgot to same the tool file when i closed it
09:50 PM rue_shop1: F12 is ok
09:50 PM Tom_L: you started over?
09:51 PM rue_shop1: lowered it a bit more
09:52 PM rue_shop1: clear out some of the other overcuts
09:52 PM Tom_L: i got a plate i keep shaving off
09:52 PM rue_shop1: this piece has seen a lot of projects
09:53 PM rue_shop1: I can tell by the screw hole count
09:53 PM Tom_L: so has mine
09:54 PM Tom_L: i think i cut some pockets in it for those handles when i was making them
09:54 PM Tom_L: triggers
09:55 PM rue_shop1: ok, nice
09:55 PM rue_shop1: that order for 18 almost cleared us out
09:56 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Vise_parts/Speedhandle_profile.jpg
09:56 PM Tom_L: it's got a few more gouges in it now
09:57 PM rue_shop1: for some reason, the heads were trouble, the bit that should be 3mm is down to 2.8
09:58 PM rue_shop1: gonna try a new bit and see how they come out
09:58 PM Tom_L: yeah you gotta sharpen your tools once in a while :)
10:00 PM rue_shop1: hah
10:00 PM rue_shop1: I'm starting to learn when a bit is getting dull by sound
10:01 PM rue_shop1: for example *plink* means it was way past time to be changed :)
10:02 PM Tom_L: what's zing mean?
10:06 PM Tom_L: i had and still am learning the new sounds from this mill
10:50 PM rue_shop1: :)
10:50 PM rue_shop1: I think zing is too high a feed rate?
10:50 PM rue_shop1: and standing in a dangerous place
10:51 PM Tom_L: it's too bad they took the YT of a local shop accident offline
10:51 PM rue_shop1: the overdpin one?
10:51 PM rue_shop1: that blew thru all the walls?
10:51 PM Tom_L: they had a large flycutter that accidentally got zinged up to 20k rpm and plunged into a vise
10:51 PM Tom_L: yes
10:52 PM rue_shop1: yea, that was hyper scarry
10:52 PM Tom_L: ripped a kurt vise right off the table like butter
10:52 PM Tom_L: did you see it?
10:52 PM rue_shop1: yea
10:52 PM rue_shop1: its damn good nobody was in the way
10:53 PM rue_shop1: after going thru all that to break the brick wall too
10:53 PM Tom_L: the last one, a service guy was installing some laser equipment in one of the cncs and the spindle dropped on him
10:54 PM rue_shop1: not the same shop!?
10:54 PM Tom_L: no
10:54 PM Tom_L: i asked my buddy what happened. i'm not sure it was ever made public
10:54 PM rue_shop1: more or less than $5000 in laser equip eaten?
10:55 PM Tom_L: the guy died
10:55 PM rue_shop1: didn't drop on the person did it? og
10:55 PM rue_shop1: there must have been multiple levels of error on that
10:56 PM Tom_L: https://www.kansas.com/news/local/article233356897.html
10:56 PM Tom_L: they should have blocked the spindle
10:56 PM Tom_L: if the brake gives out, they fall
10:56 PM rue_shop1: how horrifying for the shop staff
10:56 PM Tom_L: yeah
10:57 PM Tom_L: he was an ouside vendor
10:57 PM rue_shop1: you dont expect to have to watch a service tech
10:58 PM Tom_L: my kid got layed off again after a month
10:58 PM Tom_L: they ran out of work
10:58 PM Tom_L: at the 2nd shop he was at
10:58 PM rue_shop1: hmmm
10:59 PM rue_shop1: and on the other end of the rope, nobody can get parts cause manufacuring is not available
10:59 PM Tom_L: they'd layed off others before this but he replaced a guy that OD'd so they had 1 position open
10:59 PM rue_shop1: circuit breakers are one, the mexican plant shut down
10:59 PM Tom_L: spirit isn't releasing work to them
11:00 PM rue_shop1: all the fire alarm companies are struggling to supply parts
11:00 PM Tom_L: spirit is what Boeing here became after they left town
11:00 PM rue_shop1: yea, boeing is going down
11:00 PM Tom_L: maybe, maybe not
11:00 PM Tom_L: it's tough for all of them now
11:01 PM rue_shop1: if they cant make planes that fly, they cant stay in business
11:01 PM rue_shop1: did they fix those yet?
11:01 PM rue_shop1: still grounded?
11:01 PM Tom_L: i haven't followed it but i'm sure they've come up with something
11:02 PM Tom_L: nobody's flying now anyway
11:02 PM rue_shop1: we have planes trafficing again here
11:02 PM Tom_L: i won't get on one for a very long time
11:03 PM rue_shop1: it took a week during the midst of it before I realized I hadn't heard one in a while
11:03 PM rue_shop1: there is a lot of stupid going on
11:03 PM Tom_L: it was damn eerie on 9-12
11:03 PM Tom_L: way back when
11:03 PM rue_shop1: I remember turning on the tv 9-11
11:04 PM Tom_L: you don't realize the noise you tune out until it's gone
11:04 PM rue_shop1: I turned it on befroe the second tower was hit
11:04 PM rue_shop1: they never said anything else about the pentagon strike at the same time
11:04 PM rue_shop1: there was an other plane too...
11:05 PM rue_shop1: came down in a field?
11:05 PM Tom_L: yeah, it went down in a field
11:05 PM Tom_L: passengers overtook the pilot
11:05 PM rue_shop1: dont hear those stories
11:06 PM Tom_L: https://en.wikipedia.org/wiki/United_Airlines_Flight_93
11:06 PM rue_shop1: one of the querstions thats come up in my power supply project, is
11:06 PM rue_shop1: to what resolution can the eye see the position of a meter needle?
11:07 PM Tom_L: not as much as i used to :)
11:07 PM rue_shop1: I want to make a really wide analog display
11:07 PM rue_shop1: and I have a bunch of 0.7mm fiber
11:07 PM rue_shop1: and some 64 led arrays
11:08 PM rue_shop1: if I use 2 arrays, and a line of fibers, I can have a 128 element bar graph,
11:08 PM rue_shop1: for 18V thats 0.14V/dot
11:08 PM rue_shop1: which seems too crude
11:15 PM rue_shop1: but honestly
11:15 PM rue_shop1: comparing against an analog meter, with a width of 1"
11:15 PM rue_shop1: @ 20V/inch
11:15 PM rue_shop1: not gonna see much anyhow
11:15 PM rue_shop1: I dont know the target I want to hit within
11:15 PM rue_shop1: I mean, it would be nice to dial into, say 0.05V
11:15 PM rue_shop1: I think at the time my idea was to use a digital for the voltage, and a meter for the current
11:15 PM rue_shop1: but I cant bring myself to mix them
11:16 PM Tom_L: you should set up this cad cam. i can teach you how it works then you can make just about anything
11:16 PM Tom_L: it's a bit crude because it's old but it works good
11:18 PM rue_mohr: I have another one but its a bit of a pain
11:18 PM rue_mohr: the cad on its horrid so I go make a dxf on another machine
11:18 PM Tom_L: new ones are alot nicer but so is the price
11:19 PM Tom_L: depending what i'm doing i may make just enough cad to model the cuts
11:19 PM rue_mohr: I'd have finished writing one if that damn gui issue hadn't come up
11:19 PM Tom_L: if i didn't have it, i'd have given up a long time ago
11:20 PM Tom_L: it's like any software, you gotta know it's quirks
11:22 PM rue_mohr: hahah microsoft is gradually taking over windows from the inside out with a linux kernel
11:22 PM rue_mohr: hahaha
11:22 PM Tom_L: it would be too hard for them to fix their crap
11:22 PM Tom_L: i'm happy with 7
11:23 PM rue_mohr: yea I have a 7 that is behaving
11:23 PM rue_mohr: no stupid auto forced updates
11:23 PM Tom_L: it still asks but i ignore it
11:23 PM Tom_L: 10 takes over no matter what you're doing
11:24 PM Tom_L: you should put it on that pc
11:25 PM rue_mohr: ?
11:25 PM Tom_L: you have a win7 pc?
11:25 PM Tom_L: put this cad cam on it
11:25 PM rue_mohr: me and the other tech are talking about DNS blocking the microsoft update servers so we dont have to keep fixing the computers every 2 weeks
11:25 PM rue_mohr: no
11:25 PM rue_mohr: I have a windows.... XP machine with bamcam on it
11:26 PM Tom_L: it would work on xp
11:26 PM Tom_L: iirc i may have it on NT
11:26 PM Tom_L: i don't use it there though
11:28 PM Tom_L: anyway. gnite
11:30 PM rue_mohr: gnight
11:40 PM rue_mohr: but
11:40 PM rue_mohr: I dont really adjust a power supply via an analog meter
11:40 PM rue_mohr: maybe if its a motor or soemthing
