[00:43:32] <Tom_itx> anybody around? i have a q about tool lengths
[00:44:13] <Tom_itx> the way my mill software used to be was that i would set the z fixture offset with the tip of the first tool then preceeding tools were an offset of that
[00:44:51] <Tom_itx> ie tool one would have a zero offset
[00:45:33] <Tom_itx> do i still enter the offset for tool one as an offset from absolute z zero?
[00:45:54] <Tom_itx> and subsequent tools
[00:46:08] <Tom_itx> i think i can figure it out better by just doing it
[00:47:00] -!- Valen [Valen!~Valen@c122-108-45-139.blktn6.nsw.optusnet.com.au] has joined #linuxcnc
[00:50:36] <andypugh> Tom_itx: No, your reference / touch-off tool would normally have zero length in the table. However, having the actual physical length would also work.
[00:51:37] <andypugh> The important thing is that you should only ever touch-off the coordinate system with tool 1, so that you don't change its offsets. And you must always be careful to touch-off the other tools into the tool table.
[00:51:49] <Tom_itx> i'm just acustomed to doing it a certain way
[00:52:22] <Tom_itx> so are the other tools an offset from the first?
[00:52:30] <andypugh> However, if the other tools are correctly touched-off, then you can touch off the coordinate system with them too. (but if they are not correctly touched-off, then you break everything)
[00:52:32] <Tom_itx> if the first has zero offset
[00:52:57] <andypugh> If the first has zero offset then yes, the others are deltas.
[00:53:02] <Tom_itx> ok
[00:53:35] <Tom_itx> it's been so long since i ran the big ones i actually forgot what we did on those but i think we used a dowel pin as the first tool
[00:53:58] <Tom_itx> and most of them had routines built in to set tools
[00:54:33] <andypugh> That's a possibility too, if you have a tool-length probe.
[00:54:42] <andypugh> Time for me to sleep.
[00:54:47] <Tom_itx> ok thanks

[01:35:47] <Connor> What do you call the covers that are in front of the tables in allot of CNC mill's? It's not a way cover.. They tend to be made of stainless and typically look to be deep enough for the vise to be fully supported?
[01:36:24] <Connor> http://i132.photobucket.com/albums/q18/jid2/IMG_2214.jpg
[01:36:41] <Connor> that mill has one in front, and on the side..
[01:37:24] <Tom_itx> acordion covers
[01:37:47] <Tom_itx> oh, i dunno about those
[01:41:24] <Valen> never seen one of those before

[01:41:50] <norias> hi
[01:44:14] <pcw_home> transit FTW
[01:44:51] <Valen> 100% cloud cover here
[01:45:25] <pcw_home> I'm amazed at how much you can see with lousy binocs propped up on the deck railing projecting onto a piece of paper
[01:45:41] <Valen> do be careful doing that
[01:45:49] <pcw_home> Venus + about 7 sun spots
[01:45:57] <Valen> if the light winds up hitting the side of the tube it can cause problems
[01:46:08] <pcw_home> about 1.5" diameter sun
[01:46:26] <Valen> one of my friends was using a 10" telescope for some solar observing, was chatting to his neighbour about it
[01:46:34] <Valen> then smoke starts pouring out of the scope
[01:46:34] <pcw_home> yeah got to keep it aligned
[01:46:52] <Valen> the sun image hit the side of the tube, luckily it was fireproof cardboard
[01:46:55] <pcw_home> there goes the secondary mount...
[01:47:14] <Valen> thankfully no lol
[01:47:44] <Valen> the worst he did was "its a bit bright, i know i'll put my moon filter (eyepiece) in
[01:47:56] <Valen> it lasted about a second and a half before it exploded
[01:48:14] <Valen> (he was projecting of course)
[01:48:50] <Valen> if you put some cardboard around the binocs so your otherwise in good shadow it'll improve your contrast
[01:48:58] <pcw_home> no you want a full size filter
[01:49:01] <Valen> better still do it inside into a dark room
[01:49:23] <Valen> yeah he "well duh that was dumb" afterwards lol
[01:49:41] <pcw_home> Yeah im still amazed at how good it looks (especially if dead-on axis)
[01:49:59] <Valen> we were in the third year of our space science degree at the time lol he really should have known better
[01:50:17] <pcw_home> (glad you reminded me though, I brought the binocs in)
[01:50:35] <Valen> even a straight magnifying glass can do a decent job
[01:51:38] -!- skunkworks__ has quit [Ping timeout: 240 seconds]
[01:51:40] <pcw_home> I'd set my telescope up but 8" is a bit scary amount of sunlight
[01:51:55] <elmo40> ya, just a little, eh?
[01:52:03] <elmo40> http://www.ustream.tv/channel-popup/star-gazers-eclipse
[01:52:06] <elmo40> watch it online :)
[01:52:31] <Valen> you can normally project it onto a big screen with it
[01:52:46] <Valen> the cheat way of lining it up is to put some foil over the front of it
[01:52:54] <Valen> and punch like a 1" hole in it
[01:53:34] <pcw_home> Yeah but this is just a Dobsonian and easy to bump
[01:53:35] <Valen> http://www.nasa.gov/multimedia/nasatv/index.html
[01:54:23] <pcw_home> Yeah they had a little flare earlier
[01:54:38] <Valen> its not "that" bad
[01:54:59] <pcw_home> no I mean a solar flare
[01:55:11] <pcw_home> little bitty one on the bottom
[01:55:18] <Valen> i meant the sun isnt that bad
[01:55:40] <Valen> you normally have a few minutes of observing time
[01:56:01] <Valen> we did it with the .5 meter dob at the university
[01:56:09] <Valen> projected it onto a wall inside the building lol
[01:56:19] <Tom_itx> i suppose that's another one we aren't able to see here
[01:56:21] <Valen> (with the scope outside)
[01:56:22] <pcw_home> I alway sort of had this idea that if you didn't have a Ha filter you really could n ot see anything
[01:56:35] <Tom_itx> is it visible now?
[01:56:37] <Valen> Tom_itx: where are you?
[01:56:41] <Tom_itx> Ks usa
[01:56:41] <Valen> can you see the sun?
[01:56:51] <pcw_home> from here yes
[01:56:51] <Tom_itx> too late now i'm afraid
[01:57:04] <Valen> then you missed it
[01:57:08] <pcw_home> anyone that can see the sun can see it
[01:57:13] <Valen> started about 4 hours ago
[01:57:29] <Valen> there is a region that doesnt get to see them
[01:57:42] <Jymmm> antartica?
[01:57:46] <pcw_home> Oh ok but is pretty small
[01:58:15] <Jymmm> pcw_home: werent we able to se it at 3pm?

[02:02:07] <Tom_itx> i saw the eclipse just before the sun went behind the trees
[02:02:19] <Valen> pcw there was a lunar eclipse recently? or is it coming
[02:02:25] <Tom_itx> this is alot more rare isn't it?
[02:02:45] <Valen> yeah
[02:02:48] <pcw_home> Yes quite rare
[02:02:58] <Valen> theres 2 about 5 years apart then about 100 years for the next one
[02:03:20] <pcw_home> not sure about the lunar but there was about a 80% solar a couple weeks ago
[02:03:21] <Valen> hell i'm here because of the one 2 cycles ago
[02:03:28] <Valen> lunar is pretty common
[02:03:46] <Tom_itx> solar is less common

[02:28:11] <pcw_home> I guess only a full aperture filter is safe
[02:29:37] <Valen> oversafe for direct observation i spose
[02:30:38] <Valen> some reflective mylar would probably do if you wanted to do projected observation
[02:30:43] <Valen> i wouldn't put my eye to it

[02:31:05] <Tom_itx> i used welding goggles the other day
[02:32:06] <pcw_home> No I'm happy just to see it projected
[02:32:08] <pcw_home> (they say the .003% transparency welding goggles are OK for observing the sun)
[02:32:31] <Valen> shade 12 i think thats called
[02:32:44] <Valen> though i think they want 14 or something now
[02:33:20] <pcw_home> Well that what someone on the NASA transit show said anyway
[02:33:58] <Tom_itx> i forget the number on mine but they're pretty dark
[02:34:05] <Tom_itx> i've got spare shaded glass
[02:34:14] <Tom_itx> i can double them up and you can't hardly see a thing
[02:34:33] <Valen> i see a few spots of blue sky on the horison
[02:35:44] <Valen> "If your telescope has a finder, you should also put a filter on it or use a dust cover and secure it with tape. Unprotected viewing through the finder will lead to the same kind of optical damage as viewing through the telescope. In addition, an uncovered finder directed at the sun can lead to exceedingly unpleasant scalp burns while you're viewing."
[02:35:54] <Valen> it sounds like that is a lesson learnt the hard way
[02:37:38] <pcw_home> Ouch!

[08:09:23] <Jymmm> I could never find shit, that's why I did that. Each box is labeld with it's contents.
[08:09:55] <Jymmm> the other 4 racks have the jamie sized containers on them
[08:13:25] <Loetmichel> i am cleaning up at home... the last 3 weeks. 'til now i have discarded about 2 cubic meteres of trash... and sorted most of my tools... the room doesent look any less messy :-(
[08:13:48] <Loetmichel> ... and why the hell hso i have about 10 PCB side cutters?
[08:13:52] <Loetmichel> ;-)
[08:14:03] <Loetmichel> s/hso/do
[08:14:44] <Jymmm> you need yourself soem of these =) http://i29.tinypic.com/17daon.jpg
[08:15:18] <Jymmm> aka, toolbox #2 =)
[08:16:02] <Loetmichel> i am a cheapskate, i solve that different: http://www.cyrom.org/palbum/main.php?g2_itemId=12727
[08:16:36] <Jymmm> and THATS why it still looks messy =)
[08:16:57] <Loetmichel> company had some spare PC PSU boxes... so i made a shelf for them
[08:17:00] <Jymmm> Besides, that was FREE! Gotta love craigslist =)
[08:17:22] <Loetmichel> hrhr
[08:17:33] <Jymmm> I did give them some nice cookies though
[08:17:41] <Jymmm> as a thank you
[08:18:03] <Jymmm> ppl give away good stuff
[08:18:07] <Loetmichel> i simply havent got enouth storage to sort away all my stuff.
[08:18:18] <Loetmichel> shoud do more discarding .
[08:18:47] <Jymmm> the trick is to have a place to put it all
[08:19:07] <Jymmm> like that 6 draw cabinet, the chrome racks, etc
[08:19:53] <Jymmm> when I move, I'm just gonna shrink wrap the whoel rack and roll it on the moving truck.
[08:20:32] <Jymmm> no packing, no boxing, no stacking.

[10:24:59] <jd896> John what are we looking for when adding I in the pid pcw told me to do p ff1 I d I have done the p and ff1 it following down during cruse
[10:25:46] <jd896> I mean the following is good during cruse but how will I effect the scope reading
[10:26:59] <jthornton> I'm not that sharp on it and had to do my CHNC by trial and error... add a little watch the trace
[10:27:07] <jthornton> how close are you now?
[10:28:35] <jd896> 0.08 is perhaps the largest spike
[10:28:41] <jthornton> I mainly focused on the accel and decel part and the cruse seemed to take care of it self for me
[10:28:50] <jthornton> mm?
[10:28:58] <jd896> Yes
[10:29:24] <jthornton> iirc a plasma?

[10:53:48] <jd896> At 50 to 60 a day that's a whole morning job there mate
[10:55:55] <archivist> isnt .08 close enough for plasma?
[10:56:27] <archivist> considering iirc you mentioned some backlash
[10:57:02] <jthornton> yea, that was a pain but most of them used names that gave them away easy to delete and ban the IP
[10:57:31] <jd896> Ah the backlash is on the other axis that's still away off yet I'm not sure of the accuracy that these are ment to hold
[10:58:17] <archivist> I dont know the accuracy of plasma cuts anyway
[10:58:36] <Valen> they have a taper too
[10:58:57] <Valen> it depends on alot of stuff how accurate you can make a plasma cut
[10:59:27] <jd896> If the torch is at the right hight and speed then the edge can rival a flame cut
[10:59:46] <jthornton> the main thing I pushed for on my plasma was acceleration so I could keep the speed up when rounding a corner
[11:02:04] <Valen> thats what seem to be underestimated most with CnC
[11:02:20] <Valen> everybody espouses their rapids, bit not the acceleration as much
[11:03:20] <archivist> they dont all have all the clue :)
[11:03:40] <jthornton> some used to claim the rapid speed of both X and Y combined

[11:18:00] <jthornton> The Anilam?
[11:18:14] <jd896> Yeah
[11:18:29] <Valen> i hate needing to use the tool to make the tool
[11:18:31] <jthornton> I've had it for quite some time and it was my first CNC machine
[11:19:14] <jthornton> I used it to make my plasma after I discovered that I could actually load EMC onto a computer with the LiveCD
[11:19:27] <archivist> Valen, that requires mid work reassembly !
[11:19:43] <jthornton> every attempt at using the BDI failed
[11:19:46] <jd896> Ah so it was before emc even got a look in
[11:19:52] <jthornton> yea
[11:20:15] <jd896> Bdi ?
[11:20:45] <jthornton> that was the Brain Dead Installer for EMC before the LiveCD
[11:21:18] <jthornton> I guess my brain was dead back then dunno or my hardware was not right or something
[11:21:54] <jd896> Oh take it that's why emc's now on Ubuntu for the live cd or has it always been ubuntu
[11:22:13] <archivist> installing stuff in the brain just takes longer with age :)
[11:22:44] <jthornton> iirc the BDI was not ubuntu
[11:23:26] <jd896> Must admit Ubuntu makes Linux usable for most people
[11:24:19] <jd896> Most people don't know windows even has a command line never mind using command in Linux
[11:24:33] <jthornton> yes it does, I can't wait for cad and cam to catch up to ubuntu
[11:25:33] <jd896> Yeah that's pretty much all it needs to maybe catch solid works and autocads attention
[11:25:39] <jthornton> I started out with a 286 on DOS 4 or 5 I can't remember now
[11:26:01] <jthornton> yea that would be real nice to have a ubuntu solidworks
[11:26:53] <archivist> or an open source solidworksalike
[11:27:03] <jd896> That was most Likly before I got started John I'm only 21
[11:27:30] <jthornton> yea, that was a long time ago for sure
[11:28:06] <jd896> First one I had was a cast off 98me 2 machine
[11:28:16] <jthornton> a blank green screen with C:> burned into the left upper corner
[11:29:16] <jd896> Sounds like the old control for this esab I'm on
[11:29:23] <jthornton> mine was the deluxe model with a 10 mb hard drive and a 5 1/4 floppy and 512 mb of memory
[11:29:45] <archivist> bah you lot making me feel old...Science of Cambridge MK14 then a Commodore PET
[11:30:09] <jthornton> the Anilam motherboard is a 286 or 386
[11:30:22] <jd896> Ha I do remember those floppys that actually where floppy

[13:25:34] <jd896> Hi pcw as a continuation from the other day what am I looking for when adding I as I've noticed that it just seams to push the following error off
[13:28:25] <pcw_home> "I" should help but usually only when you are quite close
[13:28:27] <pcw_home> (it typically makes things worse with overshoots if the basic tuning is not close enough )
[13:29:58] <pcw_home> Do you have velocity mode servos?
[13:30:51] <jd896> Yes
[13:32:20] * JT-Shop collects another bit of servo tuning wisdom
[13:32:34] <pcw_home> for velocity mode servos its good to get FF1 dialed in first (this needs Halscope)
[13:34:09] <jd896> I did as you said and set p then ff1 I'm following during a cruse around 0.08
[13:34:56] <pcw_home> not so sure about wisdom, just slow osmosis after having done this a few hundred times
[13:34:58] -!- i_tarzan [i_tarzan!~i_tarzan@] has joined #linuxcnc
[13:35:36] <JT-Shop> much more experiance than my one time :-)
[13:36:08] <pcw_home> .08 inches or mm
[13:36:24] <jd896> And plenty more than my 0.5 times
[13:36:28] <jd896> Mm pcw
[13:36:28] <JT-Shop> when your tuning P and FF1 for a velocity drive what do you watch the acceleration part or the cruse part or both?
[13:36:53] <jdhNC> I have a bunch of Delta Tau systems with 'auto-tuning'. Not so great tuning.
[13:37:00] <pcw_home> FF1 is tuned by nulling the error during cruise
[13:37:12] <pcw_home> (for a velocity mode drive)
[13:37:58] <pcw_home> helps to have P low so the effect of FF1 is magnified
[13:40:13] <jd896> Yes the ff1 makes sense shal I post my latest scope to the forum
[13:40:36] <pcw_home> I would probably need a halscope plot of ferror/pidoutput/commanded and real velocity
[13:40:37] <pcw_home> to help much more
[13:41:52] <JT-Shop> jd896: what are you triggering on?
[13:41:54] <jd896> I'm looking for around 0.1 following if poss I'm at 0.4 ATM
[13:42:02] <jd896> I will do
[13:42:21] <jd896> Triggering on commanded velocity

[16:55:49] <mrsun> gah broke of the tool holder "stud" or whatever its called ... (the one that goes from the crossslide into the tool holder and have a nut on it .. like a T nut etc) .. aparently i cant even weld
[16:55:49] <mrsun> think im gonna give away all my stuff and just sit and stare into a wall soon
[17:02:19] <archivist> I think after a rest and a coffee you will repair it properly
[17:06:25] <archivist> machines of that age may have bolts/studs etc made of wrought iron, it breaks like cast iron if not annealed now and again, specially with a shock load
[17:07:02] <pcw_home> jd896_fabshop around
[17:08:00] <mrsun> archivist, it was my homemade thingie that broke
[17:09:19] <mrsun> aparently i did some porous welding and left only like 3mm square that held the stud in place, ground it all off, rewelded and what do you know .. its freakin off to to the side ... so it only grabs the T slot in the cross slide on one side and is like 1mm up in the air in the other side
[17:09:38] <mrsun> have to realy torque it down if it is to be sitting properly .. and i do not like doing that to T slots

[17:28:54] <IchGuckLive> havy poasting tonight
[17:31:22] <mrsun> archivist, ough you remember i was talking about making gears ? .. aparently the gears on my lathe is 15 degree ....
[17:31:41] <archivist> er 14.5 I bet

[17:33:01] <mrsun> reading about one making or looking for gears for the blomqvist lathe .. and aparently he had drawings and they said 15 degree =)
[17:33:23] <Connor> What's a good combination for a servo motor/driver to use as a spindle drive ? (For lathe/4th axis).. I can build my own servo using standard DC motor with H-bridge.. Just not sure if that's suitable for this or not.
[17:33:41] <Connor> Most of the motors I use are 12/24 motors for Power chair's .
[17:34:24] <IchGuckLive> MY1020 for Scooter is mutch better and cheeper
[17:34:39] <IchGuckLive> up to 1500W for 80USD
[17:35:00] <Connor> DC ?
[17:35:24] <Connor> What's the voltage ?
[17:35:53] <IchGuckLive> yes DC you can get them in 12/24/48V
[17:36:08] <IchGuckLive> look on ebay to MY1020
[17:37:03] <Loetmichel> hmmm
[17:37:13] <Connor> 2500 RPM ? That fast enough for lathe work?
[17:37:19] <archivist> mrsun, a new standard! or more like yet another gear standard, there are many
[17:37:23] <Loetmichel> is that suitable for a wheelchair (two of them)`?
[17:38:12] <Connor> okay.. I've found 24/36/48v versions.
[17:38:27] <Connor> Now to find a H-Bridge that can handle the voltage / amparage.
[17:39:11] <IchGuckLive> why not a Gecko 320
[17:40:03] <Connor> Maybe. not looked at Gecko's yet.

[17:40:23] <Connor> Do these have rear shafts on them for encoders ?
[17:40:37] <IchGuckLive> no
[17:40:52] <IchGuckLive> let me look i got a 350 in the E-Bike
[17:41:09] <IchGuckLive> how they made the frame
[17:42:33] <Connor> I think you want the encoder on the shaft of the motor, not the spindle for this would you not ?
[17:43:16] -!- syyl_ws has quit [Quit: Verlassend]
[17:43:23] <IchGuckLive> it is closed frame as i epected cause thats outside
[17:44:04] <IchGuckLive> as the motor is a very god live one you coudt desamble it and make a shaft into it
[17:47:05] <IchGuckLive> Connor: still here ?
[17:47:09] <Connor> yea
[17:47:50] <IchGuckLive> get the my1020 into google there you can see the diagramm and the other modells

[18:44:38] <mrsun> hmm, chatter in the lathe ... reasons ? .. to high rpm ? to much tool sticking out ?
[18:45:36] <archivist> also above center, too much overhang from chuck
[18:46:04] <archivist> loose headstock bearings
[18:46:18] <mrsun> got a 60mm thick piece in the chuck, with outstick about 50mm .... should be good ? :)
[18:46:26] <mrsun> archivist, headstocks bearings is more on the tight side
[18:46:45] <mrsun> (gets a bit hot when running :P)
[18:47:08] <archivist> try lower cutting speed
[18:47:09] <mrsun> tool holder (old one on the lathe) isnt the best tho ... seem to be right on center as it doesnt leave a small peg on the piece
[18:47:22] <mrsun> archivist, then i need to engage the broken backgears ... :/
[18:47:34] <mrsun> or cutting speed as in feed or rpm ? :)
[18:47:42] <archivist> yes
[18:47:51] <mrsun> sounds good when im about 10mm from the center, then the shatter stops
[18:47:58] -!- iwoj [iwoj!~iwoj@d23-16-234-107.bchsia.telus.net] has joined #linuxcnc
[18:48:10] <archivist> also tool geometry effects it
[18:49:07] <archivist> as I cannot hear it, its hard to guess what the cause is
[18:50:11] <mrsun> its a very very high pitch sound =)
[18:50:19] <archivist> whistle, tool
[18:50:27] <mrsun> i wll try tomorrow with lower rpm
[18:50:36] <mrsun> tho the gears doesnt sound to good with broken off teeth :P
[18:50:47] <archivist> put a finger on the tool does it stop
[18:50:58] <mrsun> yeah stupid person that had the lathe before made a tool holder from a round pipe to hold the small tools in
[18:51:29] <mrsun> not very rigid
[18:51:33] <mrsun> so i would guess its the tool =)
[18:51:33] <archivist> sounds like tool resonance then
[18:51:49] <archivist> shorter is better
[18:52:11] <mrsun> had no shatter at all with the new tools (16mm solid steel) but its the nut for that tool holder im remaking :P
[18:52:16] <mrsun> so have to use the old thingie =)

[20:08:38] <archivist> first gimme da money
[20:10:15] <syyl_> i already got horn boring tools :P
[20:11:11] <archivist> I dont see 50 inserts as claimed
[20:11:32] <syyl_> i think i dont need 50 ;)
[20:11:41] <syyl_> they can be resharpened pretty easy
[20:12:28] <andypugh> I see 40
[20:12:31] <archivist> I usually grind up a bit of hss when doing the small stuff
[20:12:48] <archivist> I got to 42
[20:12:53] <andypugh> They have the advantage of being significantly stiffer, being all-carbide.
[20:12:54] <syyl_> but the hss is not that shiny :D
[20:13:13] <andypugh> And with a squirty-hole down the middle
[20:13:27] <syyl_> i set up shopair down that hole

[20:22:04] <syyl_> the price isnt
[20:22:34] <Jymmm> that's the interior designers markup
[20:22:49] <syyl_> more the name
[20:22:58] <syyl_> a ewm triton is also about 2,5k euro
[20:23:11] <syyl_> and that doesnt have the slick design :d
[20:23:43] <andypugh> The Rehm is also little, so motorbike-transportable.

[20:46:27] <mrsun> riv eating
[20:46:30] <andypugh> Yes. When appropriate
[20:46:44] <frallzor> will a rivet of 6.2mm hold 4mm of sheets?
[20:46:49] <fragalot> mrsun: there's a massive welding table @ one of the workshops @ work... found out it's warped last week
[20:46:50] <syyl_> you mean the old "beat the crap out of it"-riveting?
[20:46:52] <andypugh> I work on a 1916 vehicle, so do a fair bit of it.
[20:46:52] <fragalot> >.<
[20:47:07] <frallzor> I have no idea on how much material needed to hold
[20:47:08] <archivist> frallzor, yes/no /maybe
[20:47:22] <mrsun> fragalot, hehe =)
[20:47:28] <frallzor> its pretty much just "hold" pieces together
[20:47:37] <fragalot> frallzor: if it's just to hold it together, yes
[20:47:58] <andypugh> frallzor: 6.2 is fairly large for that thickness. The material will break first.
[20:48:18] <frallzor> I went for the longest yet not biggest I could find
[20:48:20] <archivist> depends on the head size too
[20:48:34] <frallzor> seemed pretty decent
[20:49:02] <andypugh> Well, yes, I was meanign that it will pull through rather than break.

[21:02:18] <gene77> Anyway, how do I put this in metric mode, dro and all. Now that puppy has to be one of a kind since its now 95 years old!

[21:07:44] <gene77> That works, didn't know it was there. Now how do I get it to calculate the threads by the reciprocal of .7?
[21:08:04] <gene77> .7mm that is
[21:08:23] <syyl_> 0,7mm of pitch is pretty uncommon
[21:08:28] <syyl_> Oo
[21:08:35] <syyl_> sure it isnt 0,75mm?
[21:08:58] <gene77> std 4mm metric machine screw...
[21:09:12] <syyl_> arr damn :D
[21:09:15] <syyl_> right
[21:09:17] <syyl_> thats 0,7
[21:09:33] * syyl_ runs away and screams
[21:09:39] <andypugh> I just use an I of .7.
[21:10:09] <gene77> no need, I've asked far dumber questions here
[21:10:58] <syyl_> ;)
[21:11:02] <andypugh> Sorry, I don't mean I.
[21:11:14] <gene77> My code takes an input when in inches mode, of tpi, finds the reciprocal which is the movement per turn
[21:11:27] <andypugh> P is distance per rev. SO you use p 0.7
[21:12:08] <andypugh> Ah, in that case you need to use a pitch of 36.2857142857143 tpi
[21:13:06] <andypugh> Or, depending on if the code converts to metric of uses G21, you might want a pitch of 1.42857142857143 teeth per mm.
[21:13:15] -!- mhaberler [mhaberler!~mhaberler@] has joined #linuxcnc
[21:13:24] <gene77> I thought the G21 would make it do those calcs in mm, but apparently not.

[21:13:41] <andypugh> It probably does. But what does your code do?
[21:15:04] <gene77> I wrote it in inches, it takes some input figures and calculates all the vars g76 runs with
[21:15:53] <gene77> I'll try the other non-metric entries just for S&G, brb
[21:16:45] <andypugh> So, what number did you put in for the pitch?
[21:18:34] <gene77> .7 originally, i just tried the 36,etc and g76 spits out k must be greater than j error.
[21:18:55] <gene77> so i'll try tge 1.42etc
[21:19:11] <andypugh> That's the most likely.
[21:19:44] <andypugh> Better still, edit the generated G-code to say 0.7
[21:20:50] <gene77> lemme see what a debug says
[21:22:14] <gene77> Ok, now I have a #<pitch>=0.7000000
[21:24:12] <gene77> looks like you hit it.

[21:55:29] <gene77> And I just found you can't raise the cutting spindle speed, the bits lag varies & the bottom of the thread groove widens.
[21:56:06] <Tom_itx> when you touch off your tools one will have a zero offset. Does it need to be called from the program or just set in the table? I was considering using a 'dowel pin' like we used to do to set up the fixture offsets and zero for the tool offsets and sticking it high up in the tool table then referencing all the other tools from that.

[22:44:47] <theorbtwo> Humans aren't terribly good at using touch screens that are vertically in front of them. Much better when flat or at a slight angle, which will mean that the screen / computer has more leverage on the mount then otherwise.
