[00:00:17] <PetefromTn_> so is nobody gonna tell me what probe he got?
[00:00:27] <Tom_itx> i can't remember
[00:00:32] <Tom_itx> it's in your logs
[00:00:52] <PetefromTn_> OK dinner time...

[00:23:32] <FloppyDisk> @petefromTN_ I think JT got this probe: http://deepgroove1.com/stainlessprobe/stainlessprobe.htm
[00:23:59] <FloppyDisk> I pulled it off the emc mailing list. Although, there were a lot of probes suggested and I think that was it, JT to confirm.

[00:47:06] <PetefromTn_> FloppyDisk thanks for the link.
[00:47:11] <CaptHindsight> what did we have?
[00:47:12] <PetefromTn_> that looks decent actually
[00:47:47] <PetefromTn_> Oh Dacia made some Chicken Parmesan and rotini noodles
[00:48:20] <CaptHindsight> here's the deal of the week http://www.ebay.com/itm/Matsuura-760-V-2-cnc-mill-plus-free-cnc-knee-mill-Great-Deal-/262179867379

[00:48:46] <CaptHindsight> and working
[00:48:50] <PetefromTn_> yup pretty nice
[00:49:06] <PetefromTn_> Anyone getting anything cool for Christmas?
[00:49:29] <CaptHindsight> is anyone wants the knee mill I have room for the 760V :p
[00:51:13] <FloppyDisk> @PetefromTn_ You're welcome. Like I said, should confirm w/ JT, but he can simply yeah or neah...
[00:51:32] <CaptHindsight> ohh another one http://www.ebay.com/itm/MATSUURA-14C-760V-Tsudakoma-12-1-2-Hor-Vert-Rotary-Table-RNCV-300R-/301798798319 for $2500
[00:51:37] <CaptHindsight> in Florida
[00:51:43] <FloppyDisk> I got some digikey parts to make an encoder:-) otherwise, not so much...
[00:52:12] <CaptHindsight> yikes, but it looks like it was left outside :(
[00:52:27] <PetefromTn_> yeah thats a deal breaker I think
[00:52:39] <PetefromTn_> nobody getting anything cool for Christmas?

[00:55:27] <g_mouer> hi guys, have not been here in quite a while, does Andy Pugh still hang out? I'm pulling my hair out trying to bench test a redcap servo with BLDC.
[00:55:49] <CaptHindsight> stable enough to stand in?
[00:56:06] <PetefromTn_> yeah apparently ;)
[00:56:18] <PetefromTn_> we took a test ride this past weekend on them
[00:56:24] <PetefromTn_> there is a dealer in Chattanooga
[00:56:25] <CaptHindsight> g_mouer: he's around often
[00:56:35] <PetefromTn_> we took a ride down and they let us test some
[00:56:37] <CaptHindsight> must have called it an early night tonight
[00:56:41] <g_mouer> thanks capt !
[00:56:59] <g_mouer> heck of a lot easier to troubleshoot a prob here than the forum
[00:57:10] <PetefromTn_> https://www.youtube.com/watch?v=QHta4ASFC60
[00:57:14] <CaptHindsight> almost 1am his time
[00:57:50] <PetefromTn_> http://cdn3.bigcommerce.com/s-2kv17xia/products/151/images/494/skipjack90__95875.1436492523.1280.1280.jpg?c=2 Getting two of these for the kids
[00:58:06] <g_mouer> yea, my shop computer pwr supply went belly up, just got it online a few mins ago again
[00:59:13] <CaptHindsight> we have a few acre retention pond next door, been tempted to get a paddle boat
[00:59:42] <PetefromTn_> yeah man there are TONS of lakes, rivers, streams around us here.
[01:00:00] <PetefromTn_> I can't wait to start fishing from these and exploring our area.
[01:00:15] <PetefromTn_> They are gonna be also great if we ever sell our house and move back to Florida
[01:00:28] <PetefromTn_> perfect for the indian river/intercoastal
[01:00:36] <g_mouer> talking about deals, a good friend picked up 2 Kryle VMC's for $170 on a sealed bid sale from a school. modern machines, fanuc controls that lost parameters, company isn't around anymore, linuxcnc retrofits to be done once I blaze the redcap servo part of the retro for him
[01:00:38] <PetefromTn_> and lots of these guys take them out on the ocean to fish
[01:00:55] <g_mouer> that $170 included free delivery and tooling !
[01:01:15] <PetefromTn_> WOW
[01:01:42] <g_mouer> yea, hellva deal !
[01:01:46] <malcom2073> Nice!
[01:01:58] <malcom2073> Sometimes you luck into good deals
[01:02:14] <g_mouer> no, he lucks into them, I only hear about them LOL
[01:02:33] <PetefromTn_> tell him you will retro one for him for the other one ;)
[01:02:40] <g_mouer> 800 inch a minute class machines
[01:02:50] <g_mouer> ha ! I tried that Pete !
[01:03:02] <PetefromTn_> that is about like my Cincinatti
[01:03:15] <PetefromTn_> mine can do 730 or so but I am scared to ;)
[01:03:56] <g_mouer> the redcap servos thicken the plot a bit I volunteered to sort that part of the retro out
[01:04:16] <PetefromTn_> talk to PCW I think he had some info on that.
[01:04:39] <g_mouer> I know, some great minds around here
[01:04:47] <malcom2073> lol
[01:04:54] <malcom2073> Haha
[01:05:01] <malcom2073> I'm lucky if my machine does 30ipm :P
[01:05:10] <malcom2073> I'll bet the stock servos could go really fast though
[01:05:20] <PetefromTn_> the only thing great about my mind is it's ability to wander uncontrollably at any moment
[01:05:31] <malcom2073> Our matsuura 500 at work is scary fast
[01:05:48] <g_mouer> I picked up a 20 inch toolroom type cnc lathe this summer for $1000 was supposed to be dead, had it up and running in about a half hour, bad crt connection dynapath 40 control
[01:06:06] <PetefromTn_> jeez
[01:06:19] <g_mouer> one owner, from a speedshop
[01:06:23] <PetefromTn_> My CNC lathe I got for $500 but it needed the entire control and a good cleaning
[01:06:31] <PetefromTn_> Still working on it here.
[01:06:42] <malcom2073> Nice, I got my 12x36 for $250 at auction, that's the best deal I've ever gotten

[01:06:48] <malcom2073> manual
[01:06:49] <malcom2073> not cnc
[01:06:53] <g_mouer> bison chucks look brand new
[01:07:07] <PetefromTn_> I once bought a manual 16x60 asian lathe for $300
[01:07:09] <enleth> malcom2073: wow, that sounds like a great deal
[01:07:18] <malcom2073> enleth: It was, it was a tiny auction, poorly advertized
[01:07:21] <PetefromTn_> I need a chuck for this beast
[01:07:30] <malcom2073> It's a late 80's grizzly/central precision
[01:07:54] <g_mouer> just getting back into cnc and the shop after moving to SC from MY state a couple years back
[01:08:02] <malcom2073> centra/machine rather
[01:08:21] <g_mouer> built a 32x50 pole barn for a toybox, just need the floor poured to complete now
[01:08:30] <bobo__> g_mouer as Pete noted PCW may help, ssi is/was working on a servo driver supply for yellow or red caps
[01:08:40] <malcom2073> I need to get some quotes to get my polebarn poured
[01:09:16] <enleth> I'm looking into buying a lathe soon and all I can get is old east bloc crap or chinks, I can only dream of a vintage Sherline or something
[01:09:21] <g_mouer> I am extremely lucky, part retired and the place I work for does a lot of that kind of work, so I will get it done at cost.
[01:09:21] <PetefromTn_> well I got some machining to do here so I can get some cash for Christmas to pay for these damn boats ;)
[01:10:04] <g_mouer> toys come first Pete, you got it right
[01:10:09] <enleth> To add insult to injury, I can't even easily get a proper Sieg lathe
[01:10:28] <enleth> Only Sieg knockoffs
[01:11:01] <PetefromTn_> g_mouer I hear ya man. Honestly MOST of the time work comes first around here as does parts/tooling for work but I have been wanting to get some kayaks for awhile now.
[01:11:32] <PetefromTn_> We WERE going to get a pair of nice canoes but actually these kickass fishing kayaks are cheaper LOL believe it or not.
[01:12:35] <g_mouer> I followed your RF45 retro, got one myself, about half done, belt drive done, Z moving, brushless servos
[01:12:48] <PetefromTn_> Oh yeah COOL
[01:13:02] <PetefromTn_> I actually liked that little mill it was pretty decent
[01:13:16] <PetefromTn_> I redid the whole damn machine
[01:13:22] <PetefromTn_> took almost a year LOL
[01:13:38] <g_mouer> I got it before I built the barn this summer, it would fit well into my 12x24 shed
[01:14:30] <PetefromTn_> If i found a smoking deal on a used one I would get it, probably keep it manual as a second op machine for the VMC but it makes a good retrofit machine IMHO
[01:14:49] <g_mouer> then.... a bridgeport boss fell on my lap this summer, part done retro with all parts, prev owner died, wife wanted garage back, offered it to me for $300 with all the retro parts couldn't pass that up
[01:15:12] <PetefromTn_> jeez man you are a lucky one
[01:15:26] <PetefromTn_> I bought my VMC for 1300 with a bad Z axis
[01:15:32] <g_mouer> yea, this summer was a good one for finding machines
[01:15:36] <PetefromTn_> thats probably the best deal I ever got
[01:16:02] <g_mouer> local guy has a haas VF2 for $2000 OBO about a month ago, had a keyboard problem
[01:16:18] <PetefromTn_> DAMN that is a smoking deal
[01:16:19] <bobo__> so Pete how soon are taking a trip down the New River in that there boat thing?
[01:16:25] <g_mouer> I gotta stay off that damn craigslist
[01:16:35] <PetefromTn_> dunno where is the new river?
[01:17:19] <g_mouer> what part of TN you in Pete? east or west?
[01:17:23] <PetefromTn_> east
[01:17:36] <g_mouer> I'm in Anderson SC, not far away
[01:17:38] <PetefromTn_> until I can sell my damn house and then I will be PetefromFL
[01:17:50] <PetefromTn_> oh yeah
[01:17:53] <bobo__> west virginia
[01:18:01] <PetefromTn_> I am just south of Knoxvegas
[01:18:35] <PetefromTn_> we are about three miles from Chilhowee lake
[01:18:49] <g_mouer> movingis a PITA I sold off my machines, just getting more now. Kept all the tooling and such though
[01:18:50] <PetefromTn_> and not more than 5 from the Tennessee River/little river areas
[01:19:09] <g_mouer> almost neighbors
[01:19:19] <PetefromTn_> really you are that close?

[02:07:09] <toastydeath> but did it in solidworks
[02:08:43] <toastydeath> have a block, align part to a datum, subtract
[02:08:46] <toastydeath> generate toolpath

[02:59:12] <Erant> The Melin one is made in the US though

[03:24:47] <Erant> irontree9: Mills? Drills? Boring bars? Lathe tools? Little bit more specific.
[03:24:51] <gregcnc> How mcuh power do you have?
[03:24:58] <irontree9> Milling
[03:25:03] <Erant> gregcnc: Not a lot. 1/3HP :/
[03:25:20] <irontree9> tiny routing type. 1/8" or 1mm
[03:25:29] <gregcnc> trenster, I think it's just antifreeze, buy some borate and silicate free type
[03:25:46] <Erant> irontree9: What kind of material? Wood, plastic, aluminum?
[03:25:55] <irontree9> atm wood
[03:26:30] <Tom_itx> you want good ones?
[03:26:41] <Erant> Guessing that's like a single flute...
[03:27:18] <Tom_itx> http://www.lakeshorecarbide.com/ has good stuff
[03:27:28] <Tom_itx> travers.com has good stuff
[03:27:35] <irontree9> Just want one that can plunge, cut sideways and life the material out instead of packing it down
[03:27:38] * irontree9 clicks
[03:28:23] <gregcnc> for small stuff like that the kyocera stuff. i get it from this guy http://stores.ebay.com/CARBIDE-PLUS?
[03:29:03] <gregcnc> Erant, you'll want to check cutting power and torque http://zero-divide.net/index.php?page=fswizard
[03:29:22] <Erant> gregcnc: Probably going to start with 0.375 DOC, 0.05 WOC, @ 2500 RPM and 18IPM
[03:29:29] <Erant> Yeah, I use that one a lot.

[03:35:24] <gregcnc> Seems reasonable, have you been using regular cutters? I've only used roughers in my smallish manual machine last one i tested was Ø1/2", 1" DOC, .08W, maybe 1600RPM. as fast as could turn the handles made a nice shower of fine chips
[03:35:26] <irontree9> That should be good for engraving about 4mm deep into wood, yes?
[03:36:23] <Contract_Pilot> Sup All
[03:36:36] <ReadError> anyone ever seen some reliable methods for figuring out motor torque requirements?
[03:36:42] <ReadError> in the past ive just freeballed it
[03:37:05] <gregcnc> torque for what?
[03:37:07] <ReadError> but want to get the lightest suitable motor
[03:37:25] <ReadError> gregcnc: x and y axis drives
[03:37:31] <Contract_Pilot> Gun show table all set up.
[03:37:32] <ReadError> on a PNP
[03:38:04] <gregcnc> PNP?
[03:38:20] <ReadError> pick-and-place
[03:42:00] <toastydeath> oh my god my oscilloscope works
[03:42:32] <gregcnc> if you want to optimize it, need to look at mass and acceleration to get torque, there isn't much force required other than friction I would think.
[03:43:45] <gregcnc> http://machinedesign.com/motorsdrives/how-pick-motors-linear-motion
[03:43:58] <Erant> gregcnc: So this is what's confusing me a little. Melin says 0.00225" per tooth. FSWizard seems to go 0.0045" per tooth...
[03:44:09] <Erant> And I set it to HSCobalt.
[03:45:16] <gregcnc> That .002 you mention doesn't match what I found on the melin site. .0045 isn't out of line for a 3/8" cutter in aluminum
[03:45:43] <Erant> Got it from here: http://www.endmill.com/pages/training/Speed%20and%20Feed%20-%20Roughers.pdf

[03:47:38] <gregcnc> the page I sent posted the other day had different numbers. you can run slower, it's ok, but faster won't hurt the tool and it will last longer overall.
[03:48:24] <Erant> I'll give a heavier chipload a shot, see what the machine does.
[03:49:18] <Erant> 1500RPM @ ~18IPM or so.
[03:49:50] <toastydeath> how rigid is your machine - 18ipm can be a bit much, if it complains a lot keep bumping the rpm down
[03:49:55] <toastydeath> to drag the feed back too
[03:50:25] <toastydeath> (i agree w/ gregcnc about the chip load, just that the actual linear feed rate might give you problems)

[03:50:45] <Erant> I was able to do about 20IPM with a light-ish cut with a sharp endmill.
[03:51:06] <Erant> 0.05" DOC, slotting the 3/8"
[03:51:19] <gregcnc> with small machines you just have to see what works.
[03:51:27] <Erant> Which is what I'll do

[17:51:51] <Pudlo> Should I bother trying to use WD40 as a shitty cutting fluid with brass, or am I better off going dry? Cutting 1/8in brass on a CNC router with a single flute 2mm endmill.
[17:52:13] <archivist> dry for brass
[17:52:40] <archivist> but your cutter geometry is probably not the best
[17:52:45] <cradek> WD40 actually works well - for aluminum it's very helpful, but for brass I agree it's unneeded
[17:53:12] <Pudlo> kk. How do I learn this sort of thing - is there a reference for it, or is it just "learn by doing?"
[17:53:20] <cradek> hope you have extra endmills
[17:53:28] <cradek> what's your spindle speed?
[17:53:37] <archivist> run the cutter fast for brass
[17:53:45] <Pudlo> haha yeah - I'm using cheap chinese carbide and a spindle without a tach on it
[17:53:46] <Tom_itx> brass likes to grab the cutter
[17:53:50] <Pudlo> I think it's around 24K
[17:53:52] <Pudlo> ugh, I know
[17:53:58] <Pudlo> killed two endmills on the last job
[17:54:16] <Pudlo> thankfully, they're cheap chinese shit
[17:54:25] <cradek> haha, haven't heard that before
[17:54:33] <Tom_itx> well likely good ones wouldn't have broken
[17:54:44] <archivist> is it machine flex causing the breakages
[17:54:49] <Pudlo> yepp
[17:54:58] <Tom_itx> better fix that first
[17:54:58] <Pudlo> it's a really, really shitty DIY machine
[17:55:14] <Pudlo> eh, not really possible without replacing the entire machine haha
[17:55:20] <cradek> do you really need to use such a small tool?
[17:56:15] <archivist> flatten the rake for better life/less grabbing
[17:56:27] <Pudlo> re: size - unfortunately. Christmas ornaments that need some detail. Last job worked fine after I got the kinks worked out though, so I'll try this one and see how it goes.
[17:56:38] <cradek> reshaping is kinda hard to do on 2mm carbide I bet
[17:56:48] <cradek> are you trying to cut in one pass?
[17:57:04] <Pudlo> lol no
[17:57:08] <Pudlo> .2mm passes
[17:57:17] <Pudlo> was the only way I could get it to work
[17:57:38] <Pudlo> I'd never thought of reshaping. That's a cool idea - I might try it on some 1/8 carbide later.
[17:57:47] <Pudlo> Would I just do that with a file?
[17:57:57] <cradek> no, you'll have to use a diamond hone of some kind
[17:58:09] <archivist> also depends on the brass, soft, hard, etc. naval brass is evil
[17:58:24] <cradek> keep the diamond wet with water
[17:58:54] <archivist> naval brass is more of a bronze
[17:59:07] <Pudlo> This is just plain old C360
[17:59:36] <Pudlo> Couldn't find anywhere that sold free-machining brass, but at least this stuff is affordable
[17:59:45] <Pudlo> metal supermarkets FTW
[18:06:43] <cncbasher> pudlo: where are you located ?
[18:07:21] <Pudlo> waterloo, Canada
[18:07:47] <Pudlo> I think mcmaster carries free-machining brass, but it's $$$
[18:08:01] <cncbasher> http://m-machine-metals.co.uk/ ok may be too far , but they do supply world wide
[18:08:19] <cncbasher> and mail order
[18:08:24] <CaptHindsight> Metal Supermarkets supplies McMaster with their metals
[18:08:37] <CaptHindsight> same for graniger and few others
[18:09:03] <Pudlo> haha do they really? That's funny. Do you guys know a good north-american place to buy acetal or HDPE?
[18:09:07] <ReadError> ive actually found some pretty solid deals on amazon
[18:09:19] <ReadError> Pudlo HDPE is dirt cheap on amazon too

[18:51:06] <tiwake> erm
[18:51:21] <tiwake> depends on the tarantula I suppose
[18:51:47] <tiwake> some of them your flesh in a 3" area will fall off...
[18:52:40] <Jymmm> BTW tarantula hawk is a species of wasp. It parayzes a tarantual, lays it's eggs on it, then when they hatch they eat the tarantual alive.
[18:52:51] <tiwake> then you have to hire a bunch of cute maggots to clean things up for you
[18:53:30] <Pudlo> ew
[18:54:04] <Jymmm> puffed maggots with mango sauce?
[18:56:27] <tiwake> no, maggots to clean out the 3" gaping hole of dead flesh
[18:56:43] <tiwake> from the cute tarantula bite
[18:56:45] <tiwake> lol

[19:20:32] <gregcnc> floppydisk are you bidding on it? I thought about it, but haven't finished the retrofit on the one I already have. If it had the through spindle, I'd buy.
[19:23:32] <FloppyDisk> @gregcnc No, I'm not bidding on it - sigh. I think it would be an excellent little lathe. Too many projects as well.
[19:24:03] <FloppyDisk> @gregcnc It does look like there is a hole on the left side of the machine that I assumed was a through spindle - no?
[19:25:50] <JT-Shop> I wonder if this is any good for small part deburring? http://www.amazon.com/TRI-Global-TRIH0-STF-105DRVT-Vibratory/dp/B00CANF9NI/ref=pd_sim_sbs_60_2?ie=UTF8&dpID=412KYfeDh1L&dpSrc=sims&preST=_AC_UL160_SR127%2C160_&refRID=15THTKYB7BBFT06GYM76
[19:26:17] <gregcnc> The pneumatic drawbar actuator has no through hole. I'm not even sure if the 120 were available with 1" thru, though a brochure seems to indicate they were. 220 and 320 had 26mm through.
[19:26:54] <FloppyDisk> Oh.. Makes sense.
[19:27:47] <gregcnc> my older Compact 6 has only 16mm through and only with manual collet chuck.
[19:31:53] <gregcnc> JT, I've seen them mentioned often. Commonly used by shooters for cleaning brass.
[19:32:24] <JT-Shop> I've cleaned brass in the ones you find in the gun shops
[19:34:37] <gregcnc> So I was drilling holes in a vise, on purpose. Why would a vise be soft on top and frackin hard in the middle? I thought this was going to be easy when I checked a corner with a file. Fortunately I had some carbide tipped drills. Now I hope I can mill a counter bore for a SHCS.

[21:06:53] <Loetmichel> my old car had run 6 years without ANY oil in the diff ;)
[21:07:14] <Loetmichel> (broken driveshaft bearing seal)
[21:10:02] <gregcnc> oil is over rated https://www.facebook.com/video.php?v=1141644042531104&pnref=story
[21:13:05] <Loetmichel> gregcnc: for short perioods of time anyways. also: How did THAT happen?
[21:13:09] <Tom_itx> JT-Shop, my friend used a similar tabletop vibra-tumbler before he got his big one. it seemed to work fine
[21:13:34] <Loetmichel> on that account: i should refill the engine of my new(er) car soon
[21:13:39] <malcom2073> Heh
[21:14:16] <Loetmichel> it had started to blink me with the oil pressure light when decellereating in front of a traffic light ;)
[21:14:29] <JT-Shop> Tom_itx: thanks
[21:14:33] <Loetmichel> s/started/ started lately
[21:14:36] <malcom2073> My protege does that when I take hard left turns if its low, blinks the light very quickly
[21:14:44] <malcom2073> Usually when it gets down to 1-2qt in it it'll do that
[21:15:02] <Loetmichel> i think i will refill about 2.5 liters
[21:15:05] <Tom_itx> JT-Shop, make sure you get the right media for it and the material you're deburring
[21:15:07] <Loetmichel> to get it back to "max"
[21:15:18] <JT-Shop> I must be doing something wrong... I've upgraded to 2.7, set encoder 4 counter-mode to True and verified that
[21:15:19] <Tom_itx> shape and texture make a difference
[21:15:24] <Loetmichel> thats the usual amount when the oil lamp starts blinking ;)
[21:15:39] <JT-Shop> yea, I've been reading up on the media
[21:15:57] <Tom_itx> he had some cone and some pyramid for different things
[21:16:03] <Tom_itx> i can't recall what else he used
[21:16:13] <JT-Shop> connected the probe to +5 and QA4 but don't see it change state
[21:16:30] <Tom_itx> pullup needed?
[21:17:57] <Loetmichel> ah, nice
[21:18:04] <Loetmichel> a quart is 0.94 liters
[21:18:10] <Loetmichel> good to know ;)
[21:18:16] <Loetmichel> @ malcom2073
[21:18:24] <malcom2073> Loetmichel: Nice heh
[21:18:38] <JT-Shop> checked the probe and it works like a switch...
[21:18:43] <Tom_itx> yup

[21:20:50] <JT-Shop> checked the probe wiring...
[21:21:11] <Tom_itx> check the pin with just a wire
[21:21:17] <Tom_itx> that's all the probe is
[21:21:52] <Tom_itx> reverse logic?
[21:22:20] <robinsz> have you tried turning it off and on again?
[21:22:26] <JT-Shop> something is screwy
[21:22:37] <malcom2073> Reverse the polarity!
[21:22:51] <JT-Shop> saw the input a pin on for a bit then off and won't come back on
[21:23:46] <gregcnc> holes in vise now counterbored. that was surprisingly painless.
[21:24:14] <Tom_itx> JT-Shop, what V did you connect the probe to? and what V will the pin tolerate?
[21:24:14] <malcom2073> gregcnc: Figure out why the center was more difficult than the surface?
[21:24:21] <malcom2073> Or just not worrying about it?

[21:28:22] <JT-Shop> anyone notice if PCW put up the link for the 5i25 firmware that is more immune to serial noise?
[21:28:34] <Tom_itx> nope
[21:32:06] <JT-Shop> now I'm trying to figure out why the spindle is set to single ended when it is a differential encoder
[21:32:48] <Tom_itx> shouldn't be if you're doing rigid tapping iirc

[21:33:35] <Tom_itx> err... i used single ended on my mpg and it was differential

[21:34:34] <Tom_itx> and my spindle encoder _was_ single ended

[21:45:55] <gregcnc> malcolm2073 No idea about the hardness, best guess is the block was hard and somebody didn't soak it long enough when they annealed it before making it. It looks shop made. just happy I could make the holes myself, with tools I already had.

[22:15:59] <JT-Shop> just hard wired it and still no input a
[22:16:51] <Tom_itx> hope you didn't bugger something up
[22:17:06] <Tom_itx> JT-Shop, encoder input?
[22:17:19] <Tom_itx> is the function in the bitfile?

[22:18:09] -!- Deejay has quit [Quit: bye]
[22:18:57] <PCW> if the encoder input is set for TTL mode, grounding the input should be all thats needed
[22:20:11] <JT-Shop> ok
[22:21:05] <PCW> and you use the non-inverting input for TTL mode (it should measure ~5V when unconnected, it has a 2K pullup resistor to 5V))
[22:21:53] -!- Komzpa has quit [Ping timeout: 265 seconds]
[22:22:08] <PCW> for the 7I77 (because it has muxed encoders) you must use the encoder A (or B) HAL pin, not the GPIO pin
[22:23:12] <PCW> I think these pins are only in 2.7
[22:24:32] <JT-Shop> that's what was wrong, I had the wires in the wrong holes... I'm watching hm....input-a
[22:27:06] <PCW> its pretty had to damage encoder inputs in TTL mode (safe to +-25V momentarily)

[23:56:08] <Tom_itx> take it back to when you started and see if it works without the probe
[23:56:11] <Tom_itx> just to see
[23:56:22] <JT-Shop> doesn't make any difference
