12:27 AM perry_j1987: prob herring
01:07 AM mrec: https://www.aliexpress.com/item/32961925870.html this is interesting, it's just a spring loaded head, if the tool touches the head a brass contact will be interrupted and that's the entire sensor
01:08 AM mrec: and the normally on version uses a 0.80$ (if you buy one piece) solid state relay mosfet
01:09 AM mrec: the overtravel wires are just connected to a microswitch
01:11 AM mrec: someone can easily do that himself for a few bucks, the price is only for "that it looks like something"
01:12 AM mrec: I just disassembled my one because I was not satisfied with the diagram in the user manual (plus I cannot read chinese)
01:12 AM mrec: now everything'S pretty clear about it
01:24 AM mrec: https://imgur.com/a/QG3p5j7
01:25 AM mrec: https://imgur.com/1I1iCYv
01:56 AM rs[m]: mrec: if you build something yourself, take 6 ball bearings and 3 dowel pins, order 2 PCBs
01:56 AM rs[m]: mrec: 2 ball bearings and 1 dowel pin make 1 contact
01:56 AM rs[m]: mrec: space them 120°, connect in series, contact voltage 15-20V
02:00 AM Deejay: moin
02:01 AM mrec: rs[m]: I was just unsure how to connect it the tool is absolutely okay
02:03 AM mrec: http://www.makinopc.com/ this is the original manufacturer according to the pcb inside
02:03 AM mrec: I think they also installed some fuses
02:04 AM mrec: the black 0804 components are too thick for resistors but act as a bridge.
02:21 AM rs[m]: just saying.... if you want to build something yourself, that 3-leg kinematic contact layout should yield high precision and high repeatability (per effort). basically you could order the critical stuff from pcb manufacturers.
04:08 AM Tom_L: morning
05:23 AM JT-Cave: morning
05:23 AM JT-Cave: https://gnipsel.com/images/customers/BobG/target-sys-08.jpg
05:23 AM JT-Cave: https://gnipsel.com/images/customers/BobG/target-sys-07.jpg
06:01 AM mrec: rs[m]: do you know how accurate the tool which you are writing about is?
06:01 AM mrec: the tool setter which I have posted seems to have an accuracy of 20-30um
06:46 AM rs[m]: ?
06:46 AM rs[m]: mrec: it depends how you build it ;-)
06:47 AM rs[m]: mrec: it should be possible to achieve repeatability better than 5µ
06:51 AM rs[m]: mrec: i was going to build something like i described when i found this https://vers.by/en/blog/user-guides/vers-tsm more or less by accident
06:52 AM rs[m]: this is more or less exactly the design i had in mind
07:01 AM JT-Cave: hmm my 20x20 pin idc connectors should be here today
07:06 AM * JT-Cave goes to start his chicken chores
07:12 AM mrec: rs[m]: I think it also depends on how quick the platform is getting touched
07:12 AM mrec: some errors are predictable it seems
07:50 AM _unreal_: getting closer to finishing my laser etcher built and I just discovered I fucked up my placement of the Z LIMIT in the cad drawing
07:50 AM _unreal_: damn it
08:01 AM JT-Shop: hmm no elves showed up last night everything is where I left it and nothing is finished
08:03 AM rs[m]: mrec: of course you have to consider approach speed and delay of your circuit/debounce/...
08:56 AM Tom_L: JT-Shop, how you gonna cut the squares out?
08:56 AM JT-Cave: jigsaw, first I'll punch a couple of holes in opposite corners then saw away
08:57 AM Tom_L: holes and square looked more like a cnc job to me :)
08:57 AM JT-Cave: only took 25 minutes to punch 72 holes, that would have taken forever on the VMC lol
09:29 AM unterhaus: how did you punch the holes JT?
09:32 AM zeeshan: hi
09:33 AM Tom_L: hi
09:34 AM zeeshan: Tom :D
09:34 AM zeeshan: https://tinyurl.com/yymtfr5y
09:35 AM zeeshan: check out this tool I had to make for this 10 degree chamfter
09:35 AM zeeshan: its a pain to find a 10 degree chamfer tool
09:36 AM zeeshan: i should eventually get the one that can be adjusted for any chamfer angle -- it's kind of expensive @ $500
09:36 AM jdh]: you obviously should have made a 5 axis mill instead.
09:36 AM zeeshan: $$ :)
09:41 AM zeeshan: https://tinyurl.com/yx93xsxs
09:41 AM zeeshan: I'm trying to be cheap and not purchase a single point thread mill
09:42 AM zeeshan: I need to replicate the threads of this part.. was thinking of using the tool on the left. if my thinking is correct i don't think it will work in it's current state because there is no clearance angle in the tangential direction
09:42 AM zeeshan: on a lathe it would be easy, just rotate the tool a bit to get the clearance angle
09:44 AM zeeshan: any suggestions?? i'm thinking of grinding the carbide insert
09:52 AM Tom_L: get a thread mill )
09:52 AM Tom_L: http://onlinecarbide.com/sipithmi.html
09:52 AM jdh]: make one out of a broken tap
09:53 AM Tom_L: zeeshan, what size is it?
09:54 AM zeeshan: M40x1.5
09:54 AM zeeshan: I like this broken tap idea
09:55 AM Tom_L: you'll need a tap with deep enough threads to cut that
09:55 AM zeeshan: I have some pretty big taps that i can scrap for this but it will be a lot of grinding
09:55 AM zeeshan: another thought was to put a shim under the insert to get the clearance
09:55 AM Tom_L: is your time worth more than $50 ?
09:56 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill2.jpg
09:56 AM zeeshan: Tom problem is shipping takes forever at this point, and we're in lock down :)
09:56 AM zeeshan: You got those from that site you linked?
09:56 AM Tom_L: yessir
09:57 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Thread_mill1.jpg
09:57 AM zeeshan: why so many :D
09:58 AM Tom_L: to cover a wide range of threads
09:58 AM zeeshan: they are all 60 degree threadforms though?
09:58 AM Tom_L: yes
09:58 AM zeeshan: I guess if your hole size is small then you can only fit certain size threads
09:59 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cups2.jpg
09:59 AM zeeshan: *thread mills
09:59 AM Tom_L: then i did that to see if i could do an odd thread
09:59 AM zeeshan: nice!
09:59 AM zeeshan: and nice case for your caliper.
09:59 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Brass_cup/Brass_Cups8.jpg
09:59 AM Tom_L: thanks
10:00 AM zeeshan: i'm just starting to do my first thread mill attempt, so reading and learning about it a lot
10:00 AM zeeshan: its been a bit of a voodoo area for me
10:00 AM zeeshan: so tried to avoid it
10:00 AM Tom_L: there are inside and ouside thread clearance dimensions and they are different
10:04 AM Tom_L: http://www.carbidedepot.com/resources.htm
10:05 AM Tom_L: http://www.carbidedepot.com/formulas-tap-standard.htm
10:06 AM Tom_L: for inch, that gives int, ext minor diam
10:06 AM Tom_L: spot on for inch threads
10:09 AM Tom_L: http://www.professeurs.polymtl.ca/luc.baron/biblio/Vis_Metrique/METRIC%20THREAD.pdf
10:09 AM Tom_L: metric one
10:13 AM Tom_L: zeeshan, i wrote a macro for my cad to generate the cutter helix. the numbers from that carbidedepot chart work with no adjustments
10:17 AM zeeshan: tom from what i understand, using minor and major diameters from a chart isn't going to result in workable thread because thread mills come to a sharp point
10:17 AM zeeshan: the sharp point needs to be extend past the major diameter in the case of an internal thread
10:18 AM Tom_L: i'd practice on a piece so you get the feel for it
10:19 AM zeeshan: yea i got some aluminum scrap to test it on
10:19 AM zeeshan: it's kind of like single pointing on a lathe
10:19 AM Tom_L: yeah, i added leadin leadout moves on my macro
10:21 AM zeeshan: https://photos.google.com/share/AF1QipOVOMP4k2RcDMitd0vSwZU34NRZxuev4b8Jjgarl8Bdx_S99XqkqPZXjcIfOvmcaA?key=QVRHeURobXdJWjZJZ3UxQkkteFhfTDQ2b3M4R2p3
10:21 AM zeeshan: that's what inventor hsm is giving me
10:21 AM Tom_L: having all those also allows me to cut threads on that sherline spindle i wouldn't be able to cut
10:22 AM zeeshan: yes, thread milling is awesome :D
10:22 AM zeeshan: imagine having to tap a m40x1.5 mm thread
10:22 AM zeeshan: i would need 6' long tap handles
10:22 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent.jpg
10:22 AM Tom_L: multi pass
10:22 AM Tom_L: with the leadin leadout
10:23 AM zeeshan: now put that directly into linuxcnc so we don't need cam :D
10:23 AM perry_j1987: morning
10:23 AM Tom_L: zeeshan, JT-Cave may have done that
10:23 AM Tom_L: or at least a python utility
10:24 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Smartcam/arc_leadin_percent1.jpg
10:24 AM Tom_L: int and ext thread path
10:24 AM zeeshan: pretty sweet
10:24 AM zeeshan: can you get threads made without fine tuning the cam path now?
10:24 AM Tom_L: yup
10:24 AM zeeshan: first time around
10:24 AM zeeshan: nice.
10:25 AM Tom_L: i did a 3/8 24 the other day without checking it
10:28 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Jacobs_chuck/Chuck_adapter4.jpg
10:29 AM zeeshan: nice
10:29 AM Tom_L: 3/4 - 10? and 3/8 - 24
10:31 AM Tom_L: my macro though, i enter the cutter diameter
10:31 AM Tom_L: so it calculates to the tip like you said
10:39 AM Tom_L: zeeshan, does the chamfer tool cut to the center?
10:39 AM Tom_L: something like that you could make wider so the tip doesn't clog up
10:42 AM Tom_L: what's the cover for?
10:48 AM zeeshan: i didn't try the center, it probably cuts bad since the velocity is almost zero there
10:49 AM zeeshan: the parts is for a record player
10:49 AM Tom_L: looked like a belt cover :)
11:21 AM perry_j1987: wow
11:22 AM perry_j1987: they are apparently going to get my BOB from california to wisconsin by tomorrow heh
11:33 AM _unreal_: ?
11:34 AM _unreal_: I'm wondering if one of my rotory rasps could cut 1MM STEEL?
11:35 AM _unreal_: rotary
11:39 AM _unreal_: if it can that would be amazing, then I can just mill my steel opto limit switches
11:39 AM _unreal_: toying with making them in in aluminum but I'm afraid they will bed to easy
11:47 AM JavaBean: if you are bending 1mm alu with optical switches, there is something amiss
11:49 AM _unreal_: ?
11:49 AM _unreal_: I'm making mounts to hold optical switches
11:49 AM _unreal_: and I have a choice of steel or aluminum
11:49 AM _unreal_: I have 1mm of each
11:50 AM _unreal_: I think I'll just opt for the aluminum
11:51 AM _unreal_: I know I can cut it
11:53 AM roycroft: grr
11:53 AM roycroft: so i had to drive down to the office on a saturday morning to deal with the cable company
11:53 AM roycroft: they disptached a technician from southern oregon, 3 hours from here
11:53 AM roycroft: he showed up on time
11:54 AM roycroft: but he did not bring the equipment he needs
11:54 AM roycroft: because they did not tell him what work he would be performing
11:54 AM roycroft: he's trying to get ahold of someone from the local office
11:55 AM roycroft: meanwhile i've been here almost 3 hours and nothing has been accomplished
11:55 AM _unreal_: the joys of living in the middle of no where
11:55 AM roycroft: it's not that so much
11:55 AM roycroft: the local office is less than a km away
11:55 AM roycroft: they just don't work on weekends
11:56 AM _unreal_: or at all from the sounds of it LOL
11:56 AM roycroft: but yeah, i was not happy about having to leave for work at 6am on a saturday
11:56 AM CaptHindsight: why should they have to run this section of their business in any way that is efficient?
11:57 AM roycroft: i'm an hour from the office, in the opposite direction
11:57 AM CaptHindsight: I rarely see any that do so
11:57 AM roycroft: anyway, i was able to tether my laptop to my phone
11:57 AM roycroft: so at least i can get a few things done while waiting for the cable company to get their act together
11:59 AM _unreal_: That took longer then expected
11:59 AM _unreal_: dbl sided tap now cleaned
12:00 PM _unreal_: ready to add more to my work bed LOL
12:00 PM roycroft: perhaps it would be a good time to learn some sea shantys while the tech is trying to round up the equipment
12:01 PM _unreal_: the movie "Club Dread" had some great ones
12:02 PM roycroft: shantys are the official meme of 2021
12:03 PM roycroft: i don't want to get behind the times
12:03 PM CaptHindsight: did the tech show up in a van or truck size vehicle?
12:03 PM roycroft: a van
12:05 PM CaptHindsight: around here they share service vans and nothing gets left inside them when they return to the service depot
12:06 PM roycroft: the tech was told the drop was not working, and came prepared to repair it
12:06 PM roycroft: the problem is that the modem is misbehaving
12:06 PM roycroft: we're supposed to have a static ip address, but the modem won't accept the programming
12:06 PM roycroft: it needs to be put in bridged mode as well
12:07 PM roycroft: the tech was supposed to replace the cablemodem, but was not told that
12:07 PM roycroft: why he would drive 3 hours without spares for everything is beyond my comprehension
12:07 PM CaptHindsight: they seem to treat modems like some sort of religious icon
12:09 PM CaptHindsight: sounds to me like your service should have had problems only from Monday through Thursday
12:10 PM roycroft: i scheduled this on a saturday explicitly because we had working service and i did not want a service outage during business hours
12:10 PM roycroft: my boss wanted it done asap, and said it would be ok for the service to be down for a few minutes
12:11 PM roycroft: i told him it could well take longer than that, and he said he didn't see how it could take long to reprogram a modem
12:11 PM roycroft: it's been down for 3 hours so far today, and the guy still hasn't been able to get another modem
12:11 PM CaptHindsight: back in the old POTS days my phone went down on a Saturday morning...
12:12 PM CaptHindsight: residential repair only came out from Monday - Friday unless it was an emergency
12:12 PM CaptHindsight: my phone being down was not considered an emergency...
12:13 PM roycroft: i had a problem with my pots line about 20 years ago
12:13 PM roycroft: there was a loud hum on the line
12:13 PM CaptHindsight: so i decided to go the basement where the phone lines came in to check if the problem was internal or external
12:13 PM roycroft: i reported it, a repair technician came out when i was not home
12:14 PM roycroft: declared it was an internal wiring issue, and slapped a $120 repair bill on me
12:14 PM roycroft: i went to the demarc, disconnected the iw, and plugged a butt set into the telco side, and still had the hum
12:14 PM roycroft: i called the telco and they refused to dispatch or write off the charge
12:14 PM _unreal_: ! good lord I turned around for a second. you two are going at it LOL
12:15 PM CaptHindsight: while i was testing my connection someone else that lived in the apt building came down to do laundry and saw me working and called the police
12:15 PM roycroft: so i filed a complaint with the puc
12:15 PM roycroft: two days latter a fleet of vans showed up on my street - iirc there were 7 of them
12:15 PM roycroft: the supervisor knocked on my door, profusely apologised, and sent the techs off to trace the line
12:15 PM CaptHindsight: the police show up and see me working on fixing the wet oxidized connection and hold me in their car for an hour while they contact the telco
12:16 PM roycroft: they found a bridge tap about a mile away, and when they pulled it the line cleaned up
12:16 PM * roycroft wonders why someone would call the cops on something like that
12:17 PM CaptHindsight: they couldn't get the telco to press charges on a saturday so they let me go and I had to wait until monday for a telco tech to finish cleaning the two connections
12:18 PM CaptHindsight: the police told the scared woman that she did the right thing by calling them
12:18 PM roycroft: of course they did
12:18 PM roycroft: her calling them presented them a possible opportunity to beat someone up
12:18 PM CaptHindsight: this was in the 80's
12:19 PM roycroft: they were still beating people up in the '80s
12:19 PM roycroft: the only difference is that there was no cell phone video of it then
12:20 PM CaptHindsight: true police beatings go back >100 years
12:20 PM roycroft: they go back to the beginning of policedom
12:21 PM CaptHindsight: there was a lengthy discussion between officers about "alligator clips"
12:22 PM CaptHindsight: seems my Fluke multimeter and a few pairs of alligator clipped jumpers are actually pretty scary
12:22 PM CaptHindsight: and some hand tools
12:23 PM CaptHindsight: we might all be speaking Russian or some -stan language if they had not intervened
12:24 PM CaptHindsight: according to Back to the Future the current boogieman was Libya
12:27 PM roycroft: i bet they would have had a great time with me in similar circumstances
12:28 PM roycroft: since i used to work for a telco and have a proper butt set, can wrench, tool belt - the whole nine yards
12:28 PM roycroft: obviously that stuff must be stolen
12:29 PM CaptHindsight: I had moved just moved from the city to the burbs for the first time
12:29 PM CaptHindsight: quite a contrast
12:31 PM CaptHindsight: yeah one of the old police stories someone being charged with having "burglary tools" in the trunk of their car
12:32 PM CaptHindsight: so don't carry any tools in your trunk in case of breakdown
12:32 PM roycroft: the tech is back, having located some "non-static ip capable" modems, and exactly one "static ip capable" modem
12:32 PM roycroft: the one that might work he could not use though
12:32 PM roycroft: it was brand-new - still shrink-wrapped
12:32 PM roycroft: but in the database it was marked as a return
12:32 PM CaptHindsight: applied to the city police, the suburb rule was just don't bother going there
12:33 PM roycroft: and they cannot program one that's marked as a return
12:33 PM roycroft: and there is nobody available on the weekends to change th status
12:34 PM _unreal_: cutting my optical interupter mounts
12:35 PM roycroft: he's trying to get the script pushed to one of the non-static ip capable modems
12:35 PM Tom_L: CaptHindsight, phone taps _are_ illegal ya know
12:35 PM roycroft: i'm preparing to leave and reschedule
12:35 PM Tom_L: btw, was that the case when they had party lines?
12:35 PM roycroft: i used to have several friends who were on party lines
12:35 PM Tom_L: roycroft, may as well hang out and spend the day working
12:35 PM roycroft: i'm not sure that millennials even know what party lines are
12:36 PM roycroft: tom_l: my boss refuses to wear a mask
12:36 PM Tom_L: it _was_ intertaining :)
12:36 PM roycroft: i spend as little time in this building as possible
12:36 PM roycroft: my doctor has ordered me not to step foot in this building
12:36 PM Tom_L: roycroft, is it mandated in your county?
12:36 PM Tom_L: turn him in...
12:36 PM roycroft: yes it is
12:37 PM roycroft: i'm trying to avoid doing that
12:37 PM roycroft: because if i do he'll probably just shut down the business
12:37 PM roycroft: and i would prefer not to be unemployed
12:37 PM Tom_L: sounds like he needs a lesson taught ..
12:37 PM roycroft: he's incapable of learning the lesson
12:37 PM Tom_L: legally he can't do anything
12:39 PM roycroft: the less he would learn if he gets a visit from oregon osha would be confirmation that "government is bad"
12:39 PM Tom_L: i love it when advertisers send junk mail purposely with cardboard inside so it won't go thru the average shredder...
12:39 PM Tom_L: mine it's it like a kid with candy
12:40 PM Tom_L: eats*
12:42 PM CaptHindsight: Tom_L: the lesson was never do anything perceived as scary around stupid people
12:42 PM Tom_L: roycroft, their minimum fine is like 7 or 14k.. i forget which
12:42 PM Tom_L: per incident
12:42 PM _unreal_: what the hell.....
12:43 PM Tom_L: so if say 2 weren't wearing safety glasses, that's 2 incidents
12:43 PM _unreal_: I have a shit load of dbl sided foam tape holding a part. and the entire board slid.
12:43 PM _unreal_: and its still stuck?
12:43 PM _unreal_: I'm dumb founded
12:43 PM mrec: whatever value I enter on G53 it says G-code out of range, does anyone know how I can get that fixed?
12:43 PM mrec: I expected that after homing the machine everything would be set...
12:43 PM roycroft: like i said
12:43 PM roycroft: he would just shut down the business
12:44 PM Tom_L: mrec, did you set soft limits in the ini?
12:44 PM mrec: Tom_L: yes actually after homing I drove to that position manually ... but I cannot enter any value on G53 G53 0.1 out of range...
12:45 PM _unreal_: mrec, how large is the thing you are trying to mill
12:45 PM Tom_L: are the signs wrong in the ini?
12:45 PM mrec: ooh ... got it it must be wrong
12:45 PM mrec: soft limit = 80
12:45 PM Tom_L: -80 ?
12:45 PM mrec: min limit 80 / max limit 80
12:46 PM Tom_L: duh
12:46 PM mrec: min limit -80
12:46 PM Tom_L: if home is in the middle hes
12:46 PM Tom_L: yes
12:46 PM roycroft: if it's not obvious, my boss is one of the small fraction of the population who thinks the insurrectionists were fully justified in their assault on the capitol and that the democrats and the vice president should have been shot, along with all the other republicans who did not vote to overturn the election
12:46 PM mrec: it's a test setup anyway but still if I run G53 0 it says out of range
12:47 PM mrec: hmm .. must be Z0
12:47 PM mrec: okok everything clear
12:47 PM roycroft: he's both deranged and delusional, which is another reason i avoid the office
12:48 PM mrec: thanks!
12:48 PM Tom_L: np
12:48 PM Tom_L: roycroft, and you still work for him :)
12:48 PM CaptHindsight: roycroft: sounds more middle management to me
12:49 PM CaptHindsight: mrec: did it work?
12:49 PM captain_morgan0 is now known as captain_morgan
12:56 PM mrec: CaptHindsight: yes
12:56 PM Tom_L: he forgot the axis designator
12:56 PM CaptHindsight: AI would have caught that
12:58 PM CaptHindsight: mrec: machine not homed yet? Ignore limits set to yes?
12:58 PM mrec: in stepconf Home location is set to 70, Table Travel to -80 to 80 Home switch location 85
12:59 PM mrec: 90 shows up after homing, and I can travel to 100 (then the soft-limit kicks in)
01:02 PM mrec: bug in linuxcnc?
01:02 PM W1N9Zr0: sounds like your coordinate system has an offset
01:03 PM W1N9Zr0: machine->zero coordinate system->g54
01:03 PM mrec: HOME_OFFSET 85.0
01:04 PM W1N9Zr0: or go into view->show machine position instead of show relative position
01:04 PM CaptHindsight: The home switch location, as indicated by the HOME_OFFSET variable, must be strictly within the soft limits. That is, MIN_LIMIT < HOME_OFFSET < MAX_LIMIT.
01:04 PM mrec: W1N9Zr0: that's it
01:05 PM mrec: ok I got it now thanks
01:05 PM mrec: both things are clear to me now
01:06 PM CaptHindsight: what happens when you set your HOME_OFFSET variable outside the the soft limit range?
01:07 PM mrec: the limit will kick in and stop the machine?
01:08 PM mrec: (I probably wrote nonsense).
02:00 PM asdfasd: again problems with browsing local network
02:00 PM asdfasd: :(
02:00 PM asdfasd: how to restart samba when /etc/init.d/samba dont exist?
02:02 PM asdfasd: its debian wheezy
02:19 PM roycroft: five hours and six cablemodems later, i have the same service, with a dynamic ip address, that i had when i got here
02:19 PM roycroft: i really think the cable company here are trying to emulate a telco
02:19 PM roycroft: now i get to do this all over again next saturday
03:04 PM gigasu_shida is now known as gigas_cedar
03:12 PM Tom_L: roycroft, at least you have something to look forward to
03:37 PM roycroft: yeah
03:38 PM roycroft: well i'm taking monday off, since saturday was a total bust
03:38 PM roycroft: my boss is not happy about that, but he's never happy about anything, so i won't let his bad attitude get in the way :)
04:16 PM CaptHindsight: roycroft: next time you fool the cable co by not having your system ready for the new modem
04:18 PM JT-Shop: just punched the 135th hole in the panels... time to put the panel punch up
04:20 PM CaptHindsight: JT-Shop: SS panels? I don't recall the material
04:21 PM _unreal_: so I have two 18 click per turn encoder wheels
04:21 PM JT-Shop: just carbon steel panels
04:24 PM unterhaus_: I think comcast is reading y'alls comments bad mouthing the cableco
04:24 PM unterhaus_: they keep booting me
04:28 PM roycroft: i was no dealing with comcast/xfinity today
04:28 PM roycroft: it was charter/spectrum
04:47 PM Tom_L: JT-Shop, pics..
04:47 PM perry_j1987: seems like this 3d printed coupler piece is going to work
04:50 PM perry_j1987: https://images-na.ssl-images-amazon.com/images/I/51amFURRDML._AC_SX569_.jpg kinda like this style
04:50 PM JT-Shop: Tom_L, still working....
04:50 PM roycroft: until it breaks :)
04:51 PM perry_j1987: printed 100% infill
04:51 PM roycroft: i should not have said, that, because i'm about to get blamed for something
04:51 PM perry_j1987: now its in my fav color too heh
04:55 PM JT-Shop: 4 more HMI cutouts and I'm done for the day
05:07 PM _unreal_: ok milling two more mounts
05:07 PM _unreal_: I am really pissed off at my self for messing up the Z limit switch
05:08 PM JT-Shop: done
05:15 PM JT-Shop: didn't break me so I'm done for the day
05:17 PM perry_j1987: any of you guys used a lathe with mpg handwheels for xz
05:20 PM _unreal_: wish I had a lathe
05:25 PM Tom_L: perry_j1987, pretty sure andypugh does
05:26 PM perry_j1987: contemplating putting some on my new lathe
05:26 PM JT-Shop: Tom_L, https://gnipsel.com/images/customers/BobG/
05:36 PM jdh]: got overtravel switches?
05:37 PM JT-Cave: I use the MPG on my BP most of the time for Z
05:41 PM perry_j1987: ya this lathe has switches at both ends of each axis
05:42 PM andypugh: perry_j1987: Yes. https://photos.app.goo.gl/j1FxdBdr2u5UwqaC7
05:43 PM andypugh: On the saddle sort-of equivalent to the usual positions.
05:43 PM perry_j1987: hows it "feel" using those vs handwheels
05:43 PM andypugh: Well, there is no force feedback, so it doesn’t really “feel” at all.
05:44 PM andypugh: But it’s a good way to position for the start of cuts and for touch-off.
05:44 PM andypugh: I mainly use my lathe macros, and those start from the current position.
05:44 PM perry_j1987: was thinking of adding some rotary knobs next to the mpg wheels to select scale
05:46 PM andypugh: If you look carefully, I have exactly that above the Z handwheel
05:46 PM JT-Cave: that's how my BP is setup with a selector switch for 0.0001 0.001 0.01
05:46 PM JT-Cave: and maybe 0.1
05:46 PM andypugh: It’s actually a push-button + encoder switch. Pushing the button switches to manual.
06:01 PM Tom_L: JT-Cave, nice punch
06:03 PM Tom_L: how are you gonna label the buttons?
06:03 PM Tom_L: i assume the holes are for buttons
06:05 PM JT-Cave: I have a label maker
06:05 PM JT-Cave: 8 buttons and hmi per station
06:06 PM Tom_L: where did you soruce the buttons?
06:06 PM Tom_L: source even
06:07 PM Tom_L: my local electric supply has them but i never payed much attention to em
06:07 PM JT-Cave: everything electrical/electronic is Automation Direct
06:07 PM Tom_L: momentary?
06:07 PM JT-Cave: $4.25 each
06:07 PM Tom_L: no
06:07 PM JT-Cave: yea
06:08 PM Tom_L: lighted buttons?
06:09 PM Tom_L: i suppose that would be more for push on push off
06:10 PM JT-Cave: black so they don't show smudge marks from dirty fingers lol
06:11 PM JT-Cave: I've not see a toggle button
06:11 PM JT-Cave: https://gnipsel.com/images/customers/BobG/target-sys-16.jpg\
06:11 PM JT-Cave: shows the button labels
06:11 PM Tom_L: 404
06:11 PM Tom_L: got it
06:12 PM Tom_L: extra '\'
06:12 PM JT-Cave: https://gnipsel.com/images/customers/BobG/target-sys-16.jpg
06:12 PM JT-Cave: yea dumb keyboard... or too fast fingers lol
06:13 PM XXCoder: lol dual strike between \ and return
06:13 PM XXCoder: ' and enter is more common for me
06:13 PM JT-Cave: yup
06:13 PM Tom_L: combination of both for me
06:13 PM Tom_L: i got some crap $5 kbds
06:13 PM XXCoder: mine is fancy $100 apple keyboard :P
06:14 PM Tom_L: shift always sticks on the other pc
06:14 PM XXCoder: its now $10 a year so its worth it
06:14 PM JT-Cave: crap forgot to get the batteries for my head light out of the charger in the garage
06:15 PM Tom_L: he should be happy
06:15 PM Tom_L: are the function keys active?
06:18 PM JT-Cave: no, they don't do anything
06:19 PM Tom_L: yet
06:20 PM JT-Cave: I thought it would not be intuitive for the general public
06:20 PM Tom_L: :)
06:20 PM Tom_L: no but they _will_ push them
06:20 PM JT-Cave: I bet they will
06:21 PM Tom_L: wire one to a bull horn
06:21 PM JT-Cave: I should program them to put send money to JT
06:21 PM Tom_L: thank you for you generous donation to xxxx
06:22 PM JT-Cave: lol
06:22 PM Tom_L: far worse when they think they've already done it
06:22 PM JT-Cave: Your CC has been charged $100 for that...
06:24 PM Roguish2: check checkt
06:24 PM Roguish2: wow, it got thru
06:25 PM Roguish2: JT-Cave   little help with a 7i80
06:25 PM Tom_L: what sort of help?
06:25 PM Tom_L: i've got one sitting here
06:25 PM Roguish2: how to get it going.
06:25 PM Roguish2: tried everything.
06:25 PM Tom_L: did you set up a static ip on the pc?
06:25 PM Roguish2: all I get is '7i80 no found'
06:26 PM Tom_L: we will get there TONIGHT!
06:26 PM Roguish2: Tom_L.     yes.  the doc says the default ip is
06:27 PM Roguish2: set a static IP to that.
06:27 PM JT-Cave: change it to I assume and use that
06:27 PM JT-Cave: chow time here
06:28 PM Tom_L: yeah i'd set up the static to the 10. ip
06:28 PM JT-Cave: Roguish2, you can't have tried everything otherwise it would be working
06:28 PM Tom_L: ^^
06:28 PM Roguish2: JT-Cave.   ok.  I saw that in the forum, but went with the doc
06:28 PM Roguish2: JT-Cave,   yeah, yeah.
06:28 PM Tom_L: lemme boot the linux box
06:29 PM Roguish2: and now hexchat won't let me post.
06:30 PM Tom_L: seems it is
06:30 PM JT-Cave: if you use you need to set a static ip on the pc to or something like that
06:30 PM JT-Cave: but you just did post
06:30 PM Roguish2: yes, I am posting here with Freenode's webchat...
06:31 PM JT-Cave: Roguish2, you can't set the static ip to the same as the board
06:31 PM Tom_L: Roguish2, did you register your nick? that may be why
06:31 PM Roguish2: i'm going  back out to the shop.... be back in a min.
06:32 PM JT-Cave: so if you're using you need to set the static to 192.168.1.somethingelse
06:33 PM JT-Cave: pork chops with baked potato with sour cream, bacon, butter and cheese... I'm going to regret that in the morning
06:33 PM JT-Cave: oh and green onions on top
06:33 PM Tom_L: W1 W2 down the ip is fixed at
06:33 PM Roguish55: back
06:33 PM Tom_L: W1 W2 down the ip is fixed at
06:34 PM Tom_L: W1 down W2 up set from the eeprom
06:34 PM Tom_L: ie you can set it yourself
06:34 PM Roguish55: down now
06:34 PM JT-Cave: <JT-Cave> so if you're using you need to set the static to 192.168.1.somethingelse
06:34 PM Tom_L: i would go with the 10.10.10.xx ip personally
06:34 PM JT-Cave: me too
06:35 PM Tom_L: so set W1 down and W2 up
06:35 PM Roguish55: ok, changed the static IP to .122
06:35 PM JT-Cave: less chance of an ip clash
06:35 PM * JT-Cave is smelling chops... gotta go
06:35 PM Tom_L: then change your static ip on the PC to or such
06:36 PM Tom_L: ok you wanna work with the 192 address?
06:37 PM Roguish55: don't really care what IP the board is.
06:37 PM Roguish55: my whole house is on 192.168.10.......
06:37 PM Tom_L: is the board connected directly to a lan card?
06:37 PM Tom_L: board meaning the 7i80
06:37 PM Roguish55: boards is directly on the lan card. yes.
06:38 PM Tom_L: if not, it should be
06:38 PM Tom_L: ok, let's get it talking first but i would recomend changing to the 10.10.10.xx ip for the mesa card
06:39 PM Tom_L: so your pc static ip is right?
06:39 PM Roguish55: what, change the pc ip to 10.10.10.xx ?
06:39 PM Roguish55: ok
06:39 PM Tom_L: yes but not yet
06:40 PM Roguish55: yes it is /  24
06:40 PM Tom_L: power up the mesa card and plug the cable directly into the lan card and the mesa card
06:40 PM Roguish55: power up?  you mean apply the 5v
06:40 PM Tom_L: yes
06:41 PM Roguish55: done
06:41 PM Roguish55: and just plugged in the rj45
06:41 PM Roguish55: board's leds are twinkling
06:41 PM Tom_dev: mesaflash --device 7i80 --addr --readhmid
06:42 PM Roguish55: holy shit.  it worked.
06:42 PM Tom_L: :)
06:42 PM Tom_L: gawd that was easy
06:43 PM Roguish55: X)
06:43 PM Tom_L: ok now do you want to change the ip?
06:43 PM Tom_L: just to avoid confusion later with your home ip
06:43 PM Roguish55: yes
06:44 PM Tom_L: ok, power off the mesa card and switch W2 up
06:44 PM Tom_L: peter defaults the user assignable ip to
06:44 PM Tom_L: so on your pc you need to change the static ip to or something other than .10
06:44 PM Roguish55: ok, done
06:45 PM Tom_L: pc ip changed too?
06:45 PM Roguish55: no,  shouldn't that be changed after changing the boards IP?
06:45 PM Tom_L: edit the pc ip entry to the address
06:45 PM Tom_L: the board's ip is changed
06:46 PM Tom_L: you just didn't do it
06:46 PM Tom_L: it's user defineable ip is preset to
06:46 PM Tom_L: by peter
06:47 PM Tom_L: otherwise you would change that before switching, yes
06:47 PM Roguish55: ok, I get it. I think.
06:47 PM Tom_L: W2 switches it to the alternate ip
06:47 PM Tom_L: which is preset but you can change it if you like
06:47 PM Roguish55: yeah, not really clear in the docs.
06:47 PM Tom_L: i know
06:48 PM Tom_L: but that's how it works
06:48 PM Roguish55: now.       mesaflash --device 7i80  set ip=
06:48 PM Tom_L: FIXED FROM EEPROM maybe should say USER DEFINEABLE
06:48 PM Tom_dev: mesaflash --device 7i80 --addr --readhmid
06:49 PM Tom_L: you might have to power cycle the mesa card if you changed the pc ip after you switched the card
06:50 PM Tom_L: Roguish55, you're not on 192.xxx now
06:50 PM Tom_L: you're on 10.xxx
06:51 PM Roguish55: working it
06:51 PM Roguish55: ok, got that
06:52 PM Roguish55: now a 'set ip=....'
06:52 PM Roguish55: yes??
06:52 PM Tom_L: you don't need to do that
06:53 PM Roguish55: you know you're right.  im going to leave it alone......good advice.
06:54 PM Tom_L: is it visible now?
06:54 PM Roguish55: yes
06:54 PM Tom_L: cool
06:56 PM CaptHindsight: I thought that there was a howto for this
06:57 PM Tom_L: not that i'm aware of, jt may have on his site
06:57 PM Roguish55: write eprom
06:57 PM Roguish55: :b
06:58 PM Roguish55: there's sort of one by tommylight in the drivers section of the forum.
06:59 PM Roguish55: does not mention moving the jumper....
07:00 PM Roguish55: or starting out with the   address.
07:00 PM Tom_L: P7 of the docs is about it for the jumper
07:00 PM Tom_L: it does say the 192 addy is default
07:00 PM Tom_L: it could be clearer
07:01 PM Roguish55: wrote the bit file.  and power cycled.
07:01 PM Roguish55: THANK YOU SO MUCH.
07:01 PM Tom_L: the new config should show up with readhmid
07:02 PM Roguish55: yes it does
07:02 PM Tom_L: cool
07:02 PM Roguish55: how are you with spindles and vfd's
07:02 PM Tom_L: this was too easy
07:03 PM Tom_L: wish noobs were like that
07:03 PM Roguish55: i'm converting a new PM940V..   has a vfd on the spindle
07:03 PM Tom_L: i wired up my spindle vfd with 0-10v so that's about it for me
07:03 PM Tom_L: no modbus
07:04 PM Roguish55: well, that's my quandary.  which way to go.
07:04 PM Roguish55: really want to rigid tap.
07:04 PM Tom_L: analog (pwm) is probaby easier
07:04 PM Tom_L: been there done that :)
07:05 PM Tom_L: https://www.youtube.com/watch?v=EV7crK24eCE
07:06 PM Roguish55: encoder on yo0ur spindle?
07:06 PM Tom_L: yes
07:06 PM Tom_L: but it's just for sync motion, the vfd is using the motor feedback
07:06 PM Roguish55: I like that practice in wood.  good idea
07:07 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Motor_Mounted2.jpg
07:07 PM Roguish55: sync as in rigid tapping.....
07:07 PM Tom_L: before i remounted the encoder but that's my setup
07:07 PM Tom_L: rigid tapping or sync axis motion
07:08 PM Tom_L: i started off with a sherline and now the only thing left sherline is the spindle itself
07:09 PM Tom_L: i _did_ do rigid tapping with the sherline too though
07:09 PM Tom_L: just not practical
07:09 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/Control_Pannel1.jpg
07:10 PM Tom_L: overall of my setup
07:10 PM Tom_L: crude but very functional
07:10 PM Roguish55: my current panel makes your's look uber professional.
07:10 PM Tom_L: hah
07:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Control2.jpg
07:11 PM Roguish55: have a bridgeport series II that belongs to a friend.  it's huge.  5500#
07:11 PM Tom_L: i wouldn't bet on it
07:11 PM Tom_L: my friend had a boss5
07:11 PM Roguish55: naw.  I still win
07:12 PM Tom_L: most of what was on the door is gone now though
07:12 PM Tom_L: that was all for the sherline spindle
07:12 PM Roguish55: anyway, I just bought a precisionmatthews 940v.  benchtop that weighs like 1300#
07:12 PM Roguish55: soon as i'm done converting I'm going to kick the BP out.
07:13 PM Tom_L: the mill has a 7i90 in it now but the 7i80 is the same board with ethernet
07:14 PM Tom_L: 72 io
07:14 PM Roguish55: i have a 6i24 running the BP
07:14 PM Tom_L: servo or stepper?
07:15 PM Roguish55: dc brushed servos
07:15 PM Tom_L: nice
07:15 PM Roguish55: the motors are wholely undersized. but work fine 'cause I don't push it hard.
07:16 PM Tom_L: i'm rather conservative with mine
07:16 PM Roguish55: faster usually means more mistakes.
07:16 PM Tom_L: but i had to be with the sherline motor
07:16 PM Tom_L: i'm still learning what the new spindle motor can do
07:18 PM zeeshan: i've learned a lot about clean panel design in the last couple of years
07:18 PM Roguish55: i'm going to rig up an encoder on the spindle tommorow, and run it back into the mesa board.
07:19 PM Tom_L: does your vfd use the hall from the motor?
07:20 PM Roguish55: no. don't think so.  it's hooked up very simply right now.  fwd/rev/off  with a pot for speed.
07:21 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Spindle/BLDC_Wiring2.jpg
07:21 PM Tom_L: the thin wires are from the hall sensor on the motor
07:22 PM Tom_L: i do use my encoder to check the motor rpm in linuxcnc though
07:22 PM Roguish55: which brand is that?
07:22 PM Tom_L: and set the pwm for the 0-10v
07:23 PM Roguish55: are you using a PID loop for the spindle?
07:23 PM zeeshan: https://photos.google.com/share/AF1QipN1L7TKNm_jfi-66bK2lulbYhmEDLOlf-ei41BrcNF_FcJidx_ZfyetFegfV7TpUQ?key=VkpMYWV4dzV6WW9vU3JTMlpBcXZZWTdLQU5oRUxB

07:23 PM Tom_itx: there's the china source for it
07:23 PM zeeshan: panduit city
07:23 PM Tom_itx: i got it thru glockcnc which i somewhat regret now
07:24 PM Tom_itx: zeeshan, showoff :)
07:24 PM Roguish55: ^^^^^
07:24 PM zeeshan: hey man my next panel will look like that
07:24 PM zeeshan: i have yet to own a panel like that
07:24 PM zeeshan: that's work stuff
07:24 PM Tom_itx: i figured that
07:25 PM zeeshan: i wasted so much time finding used enclosures
07:25 PM _unreal_: ok X and Y limit switches on the laser etcher done
07:25 PM _unreal_: fucked my self on Z
07:25 PM Tom_L: tmi
07:25 PM zeeshan: i can buy a cabinet for $300 which is cheaper than the two enclosures i paid for the mill
07:25 PM _unreal_: screwed up my cad drawing in one of the interupter locations
07:25 PM _unreal_: dont know what I was thinking
07:26 PM _unreal_: I didnt even pick up on it till just today
07:26 PM zeeshan: you learn by doing :D
07:26 PM XXCoder: fancy
07:26 PM Tom_L: zeeshan, some do, some don't
07:26 PM zeeshan: haha
07:26 PM _unreal_: let me snap a photo of current progress
07:26 PM zeeshan: you want to know the funny thing about these panels
07:26 PM zeeshan: it looks like crap underneath the panduit
07:26 PM zeeshan: what a mess
07:27 PM zeeshan: we had a couple sensors wired wrong, it was almost impossible to trace the wire
07:27 PM Tom_L: all the same color wire too ehh?
07:27 PM zeeshan: yea the good old blue.
07:28 PM zeeshan: you'd thing wire tags would help.... they do... when they are correct
07:28 PM zeeshan: :D
07:28 PM zeeshan: i really like igus cables
07:28 PM zeeshan: they're cheap. and they're well made. one feature i didn't know about till last year was they're numbered
07:28 PM zeeshan: every few inches
07:29 PM Tom_L: no zeeshan that's just the feet count on the wire :)
07:29 PM _unreal_: https://cdn.discordapp.com/attachments/717411349541683212/800171575680696340/16108461359637609017600789804807.jpg

07:29 PM zeeshan: it's odd it'd say 1 feet every few inches :D
07:29 PM zeeshan: haha
07:29 PM _unreal_: there are some photos of current work
07:30 PM zeeshan: looking good
07:30 PM zeeshan: what are you building?
07:30 PM zeeshan: a router?
07:30 PM Roguish55: Tom_L.   thank.  gotta go.  back tomorrow.
07:31 PM _unreal_: laser etcher
07:31 PM Tom_L: np glad to help
07:31 PM zeeshan: ah that explains the laser symbol
07:32 PM zeeshan: tom i tried something ballsy on one the new machines designs i worked on
07:34 PM Tom_L: ?
07:35 PM zeeshan: picture taking long to upload
07:36 PM Tom_L: np, i'm in and out here anyway

07:37 PM zeeshan: the green, orange thing rides on 2 linear rails that are mounted to the steel tube with an adjustable spacer in between
07:38 PM zeeshan: we were able to get those rails pretty much within .001" of each other in lateral and vertical directions
07:38 PM _unreal_: Tom_L, what cha think of the current progress on the laser etcher
07:38 PM zeeshan: it's the first time i'm mounting rails on a non-machined surface :D
07:39 PM zeeshan: it seems to be working ok so far, saves a lot of money.
07:39 PM Tom_L: is that a stacker or something?
07:39 PM zeeshan: that machine just distributes those square blocks
07:39 PM zeeshan: that shuttle is running at 70in/s
07:39 PM Tom_L: ahh between the sheets
07:39 PM zeeshan: yes
07:39 PM Tom_L: cool
07:40 PM zeeshan: i'm thinking of making a cnc plasma cutter using the same concept
07:40 PM zeeshan: nice heavy duty steel frame with linear rails mounted to it with spacers in between
07:40 PM Tom_L: not much time to get out of the way there
07:40 PM _unreal_: zeeshan, what am I looking at
07:40 PM Tom_L: he builds sheetrock machines
07:41 PM _unreal_: oh
07:41 PM zeeshan: part of a machine, i cant post all of it, trade secret :P
07:41 PM Tom_L: yeah yeah we know the drill...
07:41 PM _unreal_: do we have to grab are ankles now?
07:41 PM zeeshan: theres no way i could slot a long 8' piece of steel tubing here within a couple thou
07:42 PM zeeshan: well not without paying some good money
07:42 PM Tom_L: nope
07:42 PM zeeshan: linear rails are cheap, laser cut spacers are cheap
07:42 PM Tom_L: how much travel does it have?
07:42 PM Tom_L: 6-8'?
07:42 PM Tom_L: probably more than that
07:42 PM zeeshan: 77"
07:43 PM Tom_L: do you grip or suction the spacers?
07:43 PM zeeshan: grip w/ cylinders
07:43 PM zeeshan: suction and dust are a pain in the butt
07:44 PM Tom_L: yeah i didn't think about that
07:49 PM zeeshan: https://photos.google.com/share/AF1QipPyyAzoayCj4EUZiQu7-ZYzx6GFjBwPwhktAkS6SmpEpLi0VrC9HV-urE6ZwfLOWw?key=QjRuUjVqRHh2U2FSWkRqb09lODhZQ1ZGMnZTRXJ3
07:49 PM zeeshan: its easier to see how it works in a vid
07:50 PM zeeshan: at least part of it
07:51 PM Tom_L: i kinda figured you'd drop em all at once
07:51 PM Tom_L: gang grippers
07:52 PM Tom_L: with adjustable width
07:53 PM zeeshan: prob is variation in the width of the spacers
07:53 PM Tom_L: that's why you make em adjustable
07:54 PM zeeshan: more compexity!
07:54 PM Tom_L: maybe it's easier for a moron operator to set the spacing with buttons
07:54 PM zeeshan: the variation can be spacer to spacer
07:54 PM Tom_L: i see
07:54 PM Tom_L: the spacers are excess sheet right?
07:55 PM zeeshan: can be rejected board or even good board

07:55 PM zeeshan: the blooper reel :D
07:56 PM zeeshan: my hard stop calculations checked out
07:56 PM Tom_L: decima; point off?
07:56 PM zeeshan: rofl
07:56 PM Tom_L: :)
07:56 PM Tom_L: bet that woke you up
07:57 PM zeeshan: you know you have a good design when it can take a beating!
07:59 PM zeeshan: fuck i wish i could share some more stuff
07:59 PM Tom_L: maybe you better add some rubber bumpers there
07:59 PM zeeshan: we have all sorts of cool mechanisms
07:59 PM Tom_L: i'm sure
07:59 PM zeeshan: its so annoying it has to be this way
08:00 PM zeeshan: cause when i'm looking for ideas online
08:00 PM zeeshan: its dead end after dead end
08:00 PM Tom_L: i've been in a few big plants but not just like that
08:00 PM zeeshan: you know someone somewhere has designed a solution for the exact problem you're trying to solve
08:00 PM Tom_L: you can't generalize and get ideas from that?
08:01 PM zeeshan: i think its easy to generalize things like 'when should i use a rack and pinion, t-belt, v-belt, ball screw"
08:02 PM zeeshan: but when it's like "i need to space spacers apart so a robot can pick them up in x seconds"
08:02 PM zeeshan: its so open ended
08:02 PM zeeshan: the problem can be solved in so many ways
08:02 PM Tom_L: a friend here designed presses and such, material cutters or whatever
08:02 PM zeeshan: and each way has its intricacies
08:03 PM Tom_L: one you should know of is the bird decal on the old firebirds
08:03 PM Tom_L: he made the press to cut them
08:03 PM zeeshan: wow, that's cool
08:03 PM Tom_L: did alot for 3m
08:04 PM Tom_L: i got a box full of sandpaper discs from that venture
08:04 PM zeeshan: lifetime supply of sandpaper?
08:04 PM Tom_L: yup
08:04 PM zeeshan: :D
08:04 PM Tom_L: another was adult diaper material
08:05 PM Tom_L: makes good floor absorbent for spills
08:05 PM zeeshan: that's handy
08:05 PM zeeshan: i'm always used tons of shop towels haha
08:05 PM zeeshan: *using
08:06 PM zeeshan: we never used to use v-wheels at my company
08:06 PM Tom_L: road sign vacuum forms to stick the decals on the metal etc
08:06 PM zeeshan: i just decided to use it one day after seeing someone's cnc plasma design
08:06 PM zeeshan: those things are so cheap and so useful.
08:07 PM zeeshan: i guess thats the only way to come up with a design, just look at a bunch of different ones
08:30 PM _unreal_: very pleased with the progress of my laser etcher build
08:53 PM Tom_L: _unreal_, hope that axis can stop before it breaks off that photo interrupter
08:55 PM Tom_L: the rest looks pretty good
08:56 PM Tom_L: hard stops _will_ be found as zeeshan demonstrated
08:56 PM _unreal_: lol
08:56 PM _unreal_: I have HARD stops
08:56 PM _unreal_: not going to damage the opto
08:56 PM Tom_L: just looks like it _could_
