[00:02:06] <Tom_itx> do you have a boreing bar?
[00:02:49] <andypugh> The bar, yes.
[00:02:55] <andypugh> Not the holder.
[00:03:43] -!- bootnecklad_ [bootnecklad_!~bootneckl@host-78-150-5-123.as13285.net] has joined #emc
[00:03:48] <andypugh> I am hoping that if we measure the crank-case we will find that the main bearing bores are in line, and that we can machine the bearings in a lathe.
[00:04:20] <andypugh> Considering that the engie goes tight if you park on a lump in the road, I don't think it can be that critical..

[00:09:23] <PCW> [10419.841995] RTAPI: Task 1[f51e5800]: Fault with vec=14, signo=11 ip=f88d962a.
[00:09:24] <PCW> [10419.841998] RTAPI: This fault may not be recoverable without rebooting.
[00:09:27] <PCW> is what I get
[00:12:33] <Tom_itx> andypugh seems it might take some trial and error to get the boreing bar set just right
[00:13:29] <andypugh> can you cat /proc/modules
[00:13:45] <andypugh> From that, and the ip, I can work out where the problem is
[00:14:19] <andypugh> Tom_itx: Aye, I have done some line-boring, my dad has Kearns S-type
[00:14:33] <Tom_itx> http://virtualindian.org/2techbab.htm

[00:16:07] <PCW> OK so signed numbers (+-10V 13 bit) work fine (7I77 analog outputs work as expected)

[02:38:37] <emcrules_w700> anyone play with NCGUI alot?
[02:39:31] <Tom_itx> i think jt uses it liberally
[02:40:01] <emcrules_w700> trying to setup a macro for it and it's displaying every variable in the macro
[02:41:13] <Tom_itx> i haven't used it yet
[02:41:43] <emcrules_w700> it works great just not alot of docs on it. That i know of.
[02:42:48] <emcrules_w700> I setup cradeks probing routines to work with it and its super handy.

[03:25:18] <dgarr> emcrules_w700: if you post your ngcgui example on pastebin, i could look at it

[03:42:12] <emcrules_w700> im sure im probably not understanding how ncgui understands variables
[03:50:01] <dgarr> instead of using numbered variables for intermediate values (like #15, #16, #21, etc.), try using named variables like #<newxstepover> instead of #15
[03:50:26] <emcrules_w700> ok
[03:50:44] <dgarr> there are some notes for this at the top of the ngcgui.tcl file -- the first 30 numbered parameters are inputs to a subroutine
[03:50:58] <emcrules_w700> i thought it would be something like that
[03:51:08] <emcrules_w700> Thanks
[03:51:26] <dgarr> named parameters will make it more readable too:)
[03:53:03] <emcrules_w700> you did a great job i find ncgui very usefull. Have a good night

[18:04:39] <Danimal_garage> Hi JT-Shop
[18:05:09] <Danimal_garage> still waiting on pics for the grinder, it's up north so he's gotta go take some this weekend i think
[18:10:05] <JT-Shop> Hi Dan, thanks
[18:10:59] <Danimal_garage> i got my floorplan thought out for my shop when i get the new mill
[18:11:20] <JT-Shop> Great! now figure out mine for me :/
[18:11:30] <Danimal_garage> i gotta get rid of one cart which i barely use, and my computer desk
[18:11:40] <Danimal_garage> then it'll fit
[18:12:03] <JT-Shop> I managed to get the 50 ton press together and test bend some junk... seems to work well

[18:12:24] <IchGucksLive> Good evening
[18:12:32] <Danimal_garage> nice, a brake press or just a hydraulic press?
[18:12:40] <IchGucksLive> someone has expiriance with leadshine
[18:12:44] <Danimal_garage> i do
[18:12:56] <Danimal_garage> i had leadshine stepper drives

[18:13:45] <IchGucksLive> Thanks
[18:13:50] <Danimal_garage> sorry
[18:14:06] <Danimal_garage> mine might have been digital
[18:14:17] <Danimal_garage> i can look for the model if you want
[18:14:28] <Danimal_garage> they worked great, better than the gecko i had
[18:14:57] <IchGucksLive> ok i will buy both and test
[18:15:31] <Danimal_garage> i had the M880A

[18:16:53] <JT-Shop> cool, does he want any CHNC control parts?
[18:16:59] <Danimal_garage> probably
[18:17:06] <Danimal_garage> trade for part of the grinder lol
[18:17:12] <JT-Shop> yea
[18:17:37] <JT-Shop> and get them out of my way
[18:17:41] <Danimal_garage> exactly
[18:17:50] <Danimal_garage> i'm giving him my old steppers
[18:17:54] <Danimal_garage> and drives
[18:18:03] <JT-Shop> AFAIK they worked for the most part, the only broken thing was the turret encoder
[18:18:18] <JT-Shop> press http://imagebin.org/183515
[18:18:18] <Danimal_garage> why did you convert it then?
[18:18:49] <Danimal_garage> nice, much beefier than mine
[18:19:01] <JT-Shop> I didn't know at the time but the turret encoder was dragging the 24vdc buss down to 8 or so volts
[18:19:18] <Danimal_garage> ahh
[18:19:41] <Danimal_garage> emc works better i'm sure, but if it was working i dont know if i would have converted it
[18:19:49] <Danimal_garage> as new as it was
[18:20:03] <Danimal_garage> but hindsight is 20/20, huh
[18:20:18] <JT-Shop> I'm real glad I converted it as for what I saw it was not an easy control to master on your own
[18:20:19] <IchGucksLive> Danimal_garage: can i go direct from the parport to the drives ? or do i veed a optocoppler breakout board
[18:20:48] <JT-Shop> it will bend up to 1/4" mild steel
[18:20:49] <Danimal_garage> IchGucksLive: i think the drives wrere isolated, but don't quote me on that
[18:21:19] <Danimal_garage> i ran my drives off of a 7i42
[18:21:28] <Danimal_garage> they worked on 3.5v or whatever it is
[18:21:44] <Danimal_garage> 1/4" steel?? nice
[18:22:14] <Danimal_garage> IchGucksLive: i think parport would be fine
[18:22:37] <JT-Shop> yea but only about 4-6" wide for 1/4"
[18:22:43] <Danimal_garage> ah
[18:22:46] <Danimal_garage> still
[18:23:02] <IchGucksLive> ok try this also but first i think i will try a breakout board its 25Euros so better safty first
[18:23:14] <Danimal_garage> yea
[18:23:41] <JT-Shop> oh, I'm wrong... 1/8 x 26", 3/16 x 22", 1/4 x 10", 1/2 x 4"
[18:23:48] <Danimal_garage> IchGucksLive: the drives are pretty durrable
[18:24:21] <Danimal_garage> my motors were way too big for them according to the drive's ratings but they worked fine
[18:24:59] <Danimal_garage> JT-Shop: where did you get the die set?
[18:25:55] <IchGucksLive> Danimal_garage: thanks at my place i think it is the oposit drive does 4A motor only 1A
[18:26:30] <JT-Shop> NorthernTool
[18:26:31] <JT-Shop> it takes a 40 ton press, they have a 20 ton model too
[18:26:37] <IchGucksLive> Danimal_garage: can i go for the values of the gecko 540 in stepconf
[18:34:46] <Danimal_garage> IchGucksLive: good question, i don't think i messed with the settings too much between the two
[18:35:01] <Danimal_garage> JT-Shop: thanks! i got a 20t press
[18:35:07] <IchGucksLive> Danimal_garage: ? or just try out start at 5000 20000 and reduce till it fails
[18:35:36] <Danimal_garage> yea.
[18:35:50] <Danimal_garage> i think i had my step space at like 4500 or something
[18:35:55] <IchGucksLive> so this will be then dhe first stepper that reatches above 5000mm/min
[18:36:25] <Danimal_garage> i think the leadshine drives needed 2000 step space and 2000 step length
[18:36:35] <IchGucksLive> at screwlead 4mm/rev Half step
[18:37:27] <IchGucksLive> wee will see i orderd right now and delivery saturday
[18:38:01] <JT-Shop> Danimal_garage: the 20 ton model Bends steel @ 90 degrees: 1/8in. x 20in., 3/16in. x 10in., 1/4in. x 6in., 1/2in. x 2in.
[18:38:22] <IchGucksLive> do you think i need a cooling fan for the stage at 1A 24V ?
[18:41:57] <IchGucksLive> i will get some nice litel fans for the stage as i also need a 5V generator for the oprocoppler board
[18:43:54] <Danimal_garage> i didnt need a fan
[18:44:16] <Danimal_garage> JT-Shop: not bad
[18:44:27] <IchGucksLive> at 9A ?V so there are realy pretty handsom
[18:45:13] <JT-Shop> I think the 20T model is just shorter than the 40T model
[18:45:59] <Danimal_garage> IchGucksLive: yea, pretty rugged drives
[18:46:27] <A2Sheds> JT-Shop: is this press brake? http://www.northerntool.com/shop/tools/product_7902_7902

[19:42:39] <jdhNC> because they are 2 miles behind the 2nd to last place boat?

[20:08:45] <A2Sheds> less that I thought

[20:19:40] <A2Sheds> were the bars vacuum packed or just sealed?

[20:20:27] <Rogge> On the 68 footers? Where?
[20:21:07] <andypugh> In the Solent, mainly, but we went to France, the Channel Islands and Northern Ireland.
[20:21:15] <Jymmm> A2Sheds: I tossed in a 2lb jar of vacuum packed mixed nuts. When I opened it years later, the vacuum seal was still in tact, but went rancid as well.
[20:21:39] <andypugh> My log-book is a bit unusual, 5 passages, all over 500 miles

[21:36:55] <davidf> I need to make a one-shot pulse generator, preferably with a hal pin and output to an unused parport card...
[21:37:10] <davidf> parport pin i mean.
[21:37:29] <andypugh> Have you found the "oneshot' HAL component?
[21:38:09] <davidf> Need to make a lot of spot-welds on small parts, accurately timed, about 1.5 seconds or so, and be able to tweak that time length till it is just right.

[21:39:23] <davidf> 1 ms is plenty good.

[21:41:26] <davidf> Can it be done with a keystroke?
[21:41:48] <andypugh> Probably.
[21:42:01] <davidf> Or I could make a whole axis config and use some standard signal maybe?
[21:42:03] <andypugh> GUI button is easier. G-code instuction easier still.
[21:42:22] <davidf> Ah, sure.
[21:42:48] <andypugh> Does the welding head move under CNC, or is the timer all that you are doing?
[21:43:06] <davidf> I could just write a one or two line program and run it
[21:43:48] <andypugh> Seems a waste to use all of EMC2 if you just want a parport pulse.
[21:44:05] <davidf> Timer is all. I will position the parts in the welder points, clamp them shut with a fixed force, and hit the juice, and the timer will determine the pulse length.
[21:44:30] <andypugh> My spot-welder does that with a 555 timer.
[21:44:52] <jdhNC> attiny
[21:45:11] <davidf> That was my first thought, but I am right there at the computer anyway, and it's convenient
[21:45:18] <andypugh> Yeah, Arduino would work well too.
[21:45:39] <andypugh> Well, if you are at the computer...

[21:49:49] <andypugh> OK, heading off to the EMC2 machine
[21:50:37] <davidf> Thanks andypugh !
[21:51:02] <andypugh> I left out the "0x378" from the parport line, but the rest is approximately right
[21:51:32] <davidf> But how about with g-code... what did you have in mind?
[21:51:42] <andypugh> Oh, you need to addf parport.0.write thread1 too
[21:53:23] <andypugh> Well, if you were making a welding robot I would have been tempted to suggest using spindle speed as welding time, and spindle on-off for welding. That would basically involve the same stuff as I just typed in the HAL file, and a few more net commands to set up the time and start.
[21:54:13] <JT-Shop> Danimal_garage: manual lathe is single phase?
[21:54:36] <andypugh> or, possibly, a custom M-code (M101) for example, which raises and lowers the oneshot input pin using halcmd lines.
[21:55:31] <davidf> hmm... over my head. I've been looking through the hal user manual and some of it is making sense, but don't know where to look up what all capabilities are there, like stepgen, etc.

[21:56:12] <davidf> That M 101 sounds more like something I could handle LOL
[21:56:15] <andypugh> As an alternative alternative, you could put it all in a HAL file along with a loadusr command to a standalone PyVCP panel with a momentary button and a spinbox. That would be about 10 lines of XML and 15 lines of HAL.
[21:56:40] <davidf> That would be excellent!
[21:56:53] <andypugh> Give me 10 minutes.
[21:57:07] <davidf> Can you point me at some docs for how to write that pls?

[22:22:12] <davidf> I saw it, it says received a malformed DCC request from andypugh
[22:22:23] <andypugh> Ah, OK
[22:22:28] <davidf> But I don't know what that is, even...
[22:22:31] <mrsun> hell even using a small board like the D510 or whatever it was named, cheap and easy and make some program for it =)
[22:22:35] <mrsun> but then i guess emc is usable
[22:23:47] <davidf> andypugh, why not just paste the text in an email?
[22:24:23] <davidf> Whatever is easiest...
[22:24:29] <andypugh> I sent an email
[22:31:05] <davidf> andypugh, That is awesome. Thank you!
[22:31:23] <andypugh> Does it work?
[22:31:47] <andypugh> (I didn't actually have a parport to test with)
[22:31:58] <davidf> Now, can I put that into my lathe config, just like the code for the spindle speed PyVCP that is in there?
[22:32:49] <andypugh> You ought to be able to run them both at the same time, but unless you want to run them both at the same time, why?
[22:33:21] <davidf> No I didn't try it yet. i'm on a box upstairs and the emc box in downstairs in the shop. I'll have to stick this on a flash drive and transfer it.
[22:36:24] <davidf> No reason really except I typically have the lathe program running all day and if it was right there and all I had to do was a mouse click, that would be nice.
[22:37:29] <davidf> I'm going to copy this over to the other computer and play with it I will let you know how it goes asap.
[22:38:15] <davidf> andypugh, Thanks again. That was very kind of you to take the time to do that. I really appreciate it.
[22:38:35] <andypugh> I was curious about how easy it would be.
[22:38:51] <andypugh> (Answer, even easier than I thought)
[22:40:27] <davidf> Well thanks loads. JT-Shop thanks for the links. With those and andypugh 's example I should be able to wrap my mind around this stuff.
[22:40:58] <JT-Shop> happy machining davidf
[22:41:40] <davidf> OK bbl and let you know how it works! Oh boy a new toy!

[22:53:18] <Danimal_garage> occasionally
[22:53:26] <Danimal_garage> hnc has a 2hp motor i believe
[22:53:33] <Danimal_garage> so 3hp total

[22:55:31] <JT-Shop> your ok then
[22:55:33] <Danimal_garage> well, split between 2 30 amp breakers
[22:55:49] <Danimal_garage> only running spindles on 220v
[22:55:58] <JT-Shop> I run the Samson and the 308 off of 30amp
[22:56:01] <Danimal_garage> all servos are 110v and on a different circuit
[22:56:21] <Danimal_garage> i'm more concerned about the wiring
[22:56:39] <JT-Shop> in what way?
[22:56:52] <Danimal_garage> 12awg
[22:57:09] <Danimal_garage> 30 feet of it between the junction and breaker
[22:57:11] <JT-Shop> ouch, should be 8awg on a 30
[22:57:31] <JT-Shop> if it don't get warm your ok
[22:57:34] <Danimal_garage> other things on the breakers
[22:58:12] <JT-Shop> 3hp should run on 30' of 12awg
[22:58:13] <Danimal_garage> i got like 5 220v outlets between 2 30A breakers
[22:58:30] <Danimal_garage> there's breakers or fuses on each machine
[22:58:47] <Danimal_garage> might not be kosher lol
[22:59:05] <JT-Shop> you think?
[22:59:17] <Danimal_garage> never claimed to be an electrician haha
[22:59:23] <JT-Shop> if it don't get warm that short your ok
[22:59:40] <Danimal_garage> yea it should be ok i'm guessing
[23:00:09] <Danimal_garage> i do need to relocate my compressor too
[23:00:25] <Danimal_garage> i have a bunch of 6ga wire for that
[23:00:27] <JT-Shop> when I worked as an electrician we would string up temp lights till the breaker tripped then take one off... snow never collected on the wire :)
[23:00:36] <Danimal_garage> that's the biggest motor/load in the shop
[23:00:50] <Danimal_garage> 5hp, single phase
[23:00:55] <Danimal_garage> haha nice
[23:01:05] <Danimal_garage> real 5hp, not chineese 5hp
[23:01:19] <Danimal_garage> big ol' baldor
[23:01:52] <JT-Shop> not a shop vac 5 hp then
[23:01:54] <Danimal_garage> 25a
[23:02:10] <Danimal_garage> 20 feet of 6ga ok for 25A ya think?
[23:03:18] <Danimal_garage> i'm praying my new mill has encoders, i really don't want to have to buy a resolver board
[23:03:55] <A2Sheds> 25A DC low voltage? or AC?
[23:04:06] <Danimal_garage> 25a 220v ac
[23:04:21] <A2Sheds> 30A #10
[23:04:36] <Danimal_garage> so i'm good with the 6g then, huh
[23:04:52] <Danimal_garage> i already have it
[23:04:53] <JT-Shop> yea mine is 5hp and fla of 21.5
[23:05:04] <A2Sheds> in conduit or in a cable?
[23:05:15] <Danimal_garage> well this one is a cable
[23:05:18] <JT-Shop> sounds like hanging from the rafters
[23:05:25] <Danimal_garage> my shop is all steel conduit though

[23:05:44] -!- mhaberler has quit [Quit: mhaberler]
[23:05:50] <Danimal_garage> except the 115v, that's all romex
[23:06:12] <A2Sheds> you derate based on the number of current carrying conductors in the same conduit or cable
[23:06:25] <Danimal_garage> ah
[23:06:40] <Danimal_garage> i just usually ask them at home depot
[23:07:01] <JT-Shop> current capacity depends on the type of wire too
[23:07:37] <A2Sheds> yes, insulation type and type of conductor (copper vs aluminum)
[23:07:45] <Danimal_garage> it's copper, stranded
[23:07:47] -!- syyl_tb [syyl_tb!~syyl@p4FD1585E.dip.t-dialin.net] has joined #emc
[23:07:50] <JT-Shop> and number of strands
[23:08:00] <Danimal_garage> finer strand
[23:08:15] <Danimal_garage> super thick insulation
[23:08:22] <A2Sheds> the strands are for flex
[23:08:24] <JT-Shop> 12 awg SO will carry more than THHN which will carry more than romex
[23:08:25] <Danimal_garage> it's like 1.25" in diameter
[23:08:49] <Danimal_garage> 3 cable
[23:08:53] <A2Sheds> the wire should have a marking, THHN, THW, RHW etc
[23:09:12] <JT-Shop> sounds like SO cord
[23:09:34] <Danimal_garage> JT-Shop: the guy i'm buying the mill from is delivering it on his flat bed tow truck, and he's lending me his machine dollies for a while so i can move it around while i retrofit it
[23:09:46] <JT-Shop> cool
[23:10:03] <andypugh> Danimal_garage: I suspect that the lathe won't be pulling 2hp during typical machining.
[23:10:18] <Danimal_garage> type so
[23:10:19] <Danimal_garage> 600v
[23:10:27] <Danimal_garage> 3/6 1/8
[23:10:46] <Danimal_garage> andypugh: definitely not, the belt slips at about .25hp lol
[23:10:56] <JT-Shop> that will power up a battleship
[23:11:11] <Danimal_garage> nice!
[23:11:13] <JT-Shop> the 8 will be the green one
[23:11:23] <andypugh> OK, giving up on freeCAD, there appears to be no annotation for drawings..
[23:11:25] <Danimal_garage> i got it for free somewhere
[23:12:00] <davidf> andypugh, JT-Shop - that little program works perfectly. Exactly what I needed! THANK YOU andypugh !
[23:12:26] <davidf> OOPS sorry about the line two lines up... mistake.
[23:12:54] * JT-Shop strings up the ballista :)
[23:13:03] <andypugh> You can type numbers into the time box, but they won't register until you do an up-down on the arrows.
[23:13:33] <JT-Shop> didn't someone fix that in 2.5?
[23:13:47] <andypugh> No, there is a patch but it has never been pushed
[23:14:11] <davidf> OK. It is awesome. I'm so happy with that! You only had one tiny mistake - the hal command referenced weld, but the file was actually named welder. :)
[23:14:25] <andypugh> It worked here.
[23:14:46] <andypugh> <shrug>
[23:15:23] <A2Sheds> http://www.electrician2.com/calculators/wireocpd_ver_1.html here's a good calculator for wires in raceways
[23:15:24] <davidf> Hmm maybe I accidentally renamed it when I saved it. My bad. OK, you are officially perfect!
[23:15:51] <A2Sheds> you can pick up an NEC handbook as well, but it's a bit confusing if you're not used to it
[23:15:53] <Danimal_garage> cool A2Sheds, thanks
[23:16:12] <A2Sheds> SO, SOJ etc cable is different
[23:16:18] <Danimal_garage> most stuff isnt going more than 20-25 feet, so i havent been terribly converned yet
[23:16:31] <Danimal_garage> concerned*
[23:17:11] <A2Sheds> for longer runs you also have to factor in voltage drop
[23:17:39] <Danimal_garage> yea
[23:18:08] <andypugh> If you used a sensible voltage you wouldn't have so much trouble,
[23:18:39] <davidf> When I worked in a motor rewinding shop one summer, mostly the only things I saw damaged by too long / too thin wires were brushes on hand tools. The springs would heat up, lose their temper, and then the brushes and commutator would burn.
[23:18:48] <Danimal_garage> what's a sensible voltage to you?
[23:20:17] <A2Sheds> with SO or SOJ type cable all the conductors are considered as current carrying conductors so you have to derate by 80% IIRC
[23:20:41] -!- syyl_tb has quit [Ping timeout: 256 seconds]
[23:21:01] <davidf> But if voltage drops too much the rpm drops, and back-emf drops, and windings start to look like low resistances, current shoots up and stuff starts smokin'...
[23:21:46] <davidf> andypugh, still getting that malformed DCC request stuff...

[23:25:40] <davidf> Boy andypugh thanks million. I've got to get back to work now. I'll let you know how the welding works out with this new method. Counting one thousand on, one thou... didn't always work too well.
[23:26:12] <davidf> see ya later.
[23:26:22] <andypugh> I had a spot welder with just a big toggle switch (not even a button) and know how awkward it is.
[23:26:34] <andypugh> Hve fun
[23:26:56] <Danimal_garage> cnc welder?
[23:27:02] <Danimal_garage> neato
[23:27:05] <davidf> Yeah and I'm welding small stainless steel parts, and 1/10 second too long, and they're poop.
[23:27:15] <Danimal_garage> cool
[23:27:23] <andypugh> PCW: The good news is, I get the same problem as you do. The bad news is that I get the same problem as you do.
[23:27:31] <Danimal_garage> lol
[23:28:12] <PCW> Well at least its not just somthing dumb I was doing
[23:28:34] <davidf> Well, I guess technically it is cnc now, but only as far as the on/off time function. Thanks to andy.
[23:29:03] <andypugh> I think it works with a 7i49 firmware. The odd thing is that it seems to crash if you use a non-7i49 firmware
[23:30:02] <PCW> BTW the count data type does not seem to be promoted to 32 (64) bits correctly ( a 16 bit number wraps at 32767)
[23:30:03] <andypugh> It is probably the 7i49 code being called and failing to quit
[23:30:30] <andypugh> OK. I was a bit unsure about that.
[23:30:39] <PCW> OK that make sense, make everyone buy a 7I49!
[23:30:45] <Danimal_garage> ha

[23:36:05] <PCW> Maybe the encoder count promotion stuff in HostMot2 would be a good example
[23:36:42] * skunkKandT could use a promotion
[23:36:49] <Danimal_garage> same here
[23:36:54] <Danimal_garage> too bad my boss is a dick
[23:37:18] <skunkKandT> is it bad that I am streaming youtube videos and surfing while the 30 ton machine it moving around?
[23:37:22] <skunkKandT> heh
[23:37:42] <andypugh> PCW: encoder promotion is trivial because the bit-length matches the datatype. It "just happens" as a side-effect of 2s complement maths. That's not the case with the arbitrary bitlength in sserial.
[23:38:01] <Danimal_garage> skunkKandT: na, i usually walk the dogs when i have a long cycle time

[23:52:30] <PCW> mimi ninapenda pombe
[23:52:35] <JT-Shop> emcrules_w700: in ngcgui?
[23:53:04] <andypugh> No point sending you a patch for this PCW. Insert this after line 343 of resolver.c: if (hm2->resolver.num_instances <= 0) return;
[23:53:32] <PCW> ok
[23:54:13] <andypugh> OK, I never guessed that PCW really knew some Swahili
[23:54:21] <emcrules_w700> JT-Shop:lets say you have ncgui embeded with with macro1 as a tab. the macro tab has 3 parameters X=1 Y=2 Z=3. Can i populate the parameters. Create the feature change the 3 parameters to something else and then create another feature and then finalize the program.
[23:54:48] <JT-Shop> I think you have to load macro1 twice to do that
[23:55:03] <emcrules_w700> thats what i was afraind of
[23:55:13] <andypugh> PCW: resolver yangu moduli inaonekana kuwa fasta
[23:55:28] <JT-Shop> what's wrong with that?
[23:55:43] <JT-Shop> use the new tab
[23:55:45] <emcrules_w700> just alot more tabs
[23:55:56] <JT-Shop> only when you need it
[23:56:14] <Danimal_garage> andypugh: pig latin?
[23:56:43] <emcrules_w700> I was trying to emulate a flexible conversational style
[23:57:00] <andypugh> No, Swahili (from Google translate). But I don't think Swahili has a very extensive CNC-related lexicon
[23:57:06] <Danimal_garage> ha
