[00:01:03] <WalterN> or machining channel in gernal
[00:01:06] <WalterN> general
[00:01:18] <Tom_itx> there are some
[00:01:23] <Tom_itx> i forget which ones
[00:01:38] <mpictor> WalterN: talk to faunuc? read the manual?
[00:02:13] <JT_Shop> WalterN, your asking questions about Fanuc G code on the LinuxCNC channel...
[00:02:38] <JT_Shop> there are thousands of different variants of G code besides LinuxCNC
[00:02:46] <MacGalempsy> guys, after linuxcnc is running and I execute halrun in terminal, when saving, does that save as the active HAL in linuxcnc?
[00:02:50] <WalterN> and anodizing...
[00:03:11] <WalterN> and lasers/optics
[00:03:16] <JT_Shop> MacGalempsy, if I understand what your asking no
[00:03:43] <MacGalempsy> the ulitimate question is, can I edit the halfile while linuxcnc is running?
[00:03:53] <JT_Shop> WalterN, sure we talk about many things but when you ask about G code we assume you mean LinuxCNC
[00:04:15] <JT_Shop> MacGalempsy, you can but it won't take effect till you start again
[00:04:27] <JT_Shop> did you get the updated sample configuration files?
[00:05:06] <MacGalempsy> did you upload new ones? I just went back to the earlier ones that worked, and planned to try and go from there
[00:05:48] <WalterN> I just havent had a chance to change controllers at all... I will probably be converting a manual lathe into a CNC gang tooling type machine though sometime if the shop slows down :P
[00:06:02] <JT_Shop> yes, I had a mistake in the one you downloaded this morning and fixed and tested on my 5i25 7i77

[00:22:28] <JT_Shop> run linuxcnc from the menu and pick that config and let me know what the error is
[00:22:54] <MacGalempsy> ok. I will get the dmesg an put it to pastebin

[00:27:57] <CaptHindsight> wow $3200+ for a CNC wire bender
[00:28:53] <JT-Droid> Run tge config from cnc linuxcnc
[00:29:14] <MacGalempsy> i tried, that is what came up
[00:29:53] -!- kiw has quit [Ping timeout: 246 seconds]
[00:29:56] <MacGalempsy> I select it from the list, and that is the dmesg that results, even after sudo dmesg -c
[00:30:08] <JT-Droid> Did you refresh your browser?
[00:30:14] <MacGalempsy> yep
[00:30:28] <JT-Droid> Im running that confignow
[00:31:05] <MacGalempsy> are there additional download requirements then just installing the linuxcnc disk?
[00:31:11] <JT-Droid> And i dl from my web page to the mill
[00:31:41] <JT-Droid> Are you sure your running the right config
[00:32:21] <MacGalempsy> this is how I do it. there is only one folder in the configs, it is the file you posted wiht updates around 8am this morning
[00:32:30] -!- wboykinm_ has quit [Remote host closed the connection]
[00:32:52] <MacGalempsy> when I open linuxcnc, there is a list, I select the one that goes with your file, and it wont start up
[00:33:11] <MacGalempsy> the one you posted without the axis section seems to work fine
[00:33:22] <JT-Droid> Installing the livecd then running one config from the config picker zets everythingup

[00:34:18] <MacGalempsy> so run the config that works, then try to switch too the config that doesnt after linuxcnc is running?

[00:35:15] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[00:35:19] <MacGalempsy> do all the pins and stuff need to be changed before attempting to run?
[00:35:41] <JT_Shop> no, it should run out of the box with a 5i25/7i77
[00:36:13] <JT_Shop> did you put it in it's own directory?
[00:36:17] <MacGalempsy> maybe I should remove the tb1 power supply and just run for the 5i25 pwr?
[00:36:24] <JT_Shop> it/latest config
[00:36:36] <MacGalempsy> yes,the folder contents are in their own folder
[00:36:59] <JT_Shop> the 7i77 needs field power or the config will not run
[00:37:06] <MacGalempsy> it has field power
[00:37:15] <MacGalempsy> and when I do show pins, they all come on
[00:37:35] <JT_Shop> you may still have linuxcnc running then
[00:37:48] <JT_Shop> did you do a halrun and leave it oopen?
[00:38:04] <MacGalempsy> do I need to have halrun open?
[00:38:21] <JT_Shop> no, you can only run one at a time and you can'
[00:38:32] <JT_Shop> t run a latency test at the same time either
[00:38:36] <MacGalempsy> I even rebooted then tried starting it

[00:40:17] <JT_Shop> when you run from Applications > CNC > LinuxCNC and pick that config to run you should get a LinuxCNC error screen if there is a problem
[00:40:45] <MacGalempsy> yes it comes up and the whole thing shuts down
[00:40:57] <JT_Shop> what is in that error screen?
[00:41:16] <JT_Shop> that is usually the best clue
[00:42:05] <MacGarage> there is a print file information header
[00:42:31] <MacGarage> but I cannot seem to copy the info
[00:43:09] <JT_Shop> if you select all the text and press the middle mouse button or wheel it will copy then press it again to paste to a file
[00:43:11] -!- dhoovie has quit [Ping timeout: 246 seconds]
[00:43:11] <MacGarage> can not find -sec MOT -var MOT -num 1
[00:43:29] <JT_Shop> having opened up a text file and middle click in it
[00:43:29] <MacGarage> cannot find -sec EMCMOT -car EMCMOT -num 1
[00:44:04] <JT_Shop> I think that is normal
[00:45:14] <Jymmm> Click in the text area, CTRL+A to select all, CTRL+C to copy, CTRL+V to paste.
[00:45:42] <JT_Shop> sometimes that doesn't work with some interfaces in linux :(
[00:45:50] <MacGarage> http://pastebin.com/az9NNMu4
[00:45:55] <Jymmm> then they're fucked up
[00:45:55] <JT_Shop> sometimes only the middle mouse works
[00:46:11] <MacGarage> one of those combos worked, not sure which one
[00:46:20] <JT_Shop> 7i77.hal:42: Pin 'hm2_5i25.0.7i77.0.1.analogena
[00:46:22] <Jymmm> Nobody has a middle button since the 80's
[00:46:40] <JT_Shop> the wheel works too as a middle button
[00:46:53] <Jymmm> What mouse wheel?
[00:47:23] <Jymmm> ever heard of trackpads, trackballs
[00:47:32] <JT_Shop> MacGalempsy, line 37 is the error
[00:47:56] <JT_Shop> for some reason the 7i77 pins are not showing up like field power or 5v is not correct
[00:48:08] <Tom_itx> Jymmm, the middle button is for your middle finger
[00:48:17] <MacGalempsy> maybe a connection came loose
[00:48:45] <JT_Shop> I'm heading in and will watch from the droid
[00:49:00] <Jymmm> Tom_itx: Nah, top-right button, which is programed to PASTE.
[00:49:06] <MacGalempsy> tb1 has a 5v psu from a cellphone charger. fieldpower is 24v from a 100w psu
[00:49:23] <MacGalempsy> and vin and field power are shared o nthe 7i77
[00:50:12] <MacGalempsy> will go back through the wiring
[00:50:25] <MacGalempsy> so that is why the ealier one with no axis settings worked ;)
[00:50:29] <Jymmm> Tom_itx: bottom chord = BACK

[03:32:05] -!- micges has quit [Ping timeout: 245 seconds]
[03:32:09] <pzpz> what do you mean by "higher voltage"
[03:32:15] <pzpz> 90V is the max..
[03:32:29] -!- KGB-linuxcnc has quit [Remote host closed the connection]
[03:32:32] <pzpz> more you will burn it..
[03:33:29] micges1 is now known as micges
[03:33:30] <kwallace1> It is common for modern CNC machines to use higher voltage for their motors.
[03:34:16] <kwallace1> The more voltage the faster you can go.
[03:36:13] <pzpz> 3000 rpm in the X/y is 70mm / s
[03:36:35] <pzpz> more than enough for me
[03:37:43] <pzpz> and with ball screws 5 TPI it will 250mm / s
[03:38:27] <pzpz> it is very very fast for what i need
[03:38:34] <pzpz> so..
[03:38:45] <pzpz> i go with this motor
[03:40:00] <kwallace1> You already have motors?

[03:44:07] <pzpz> ?
[03:44:13] <pzpz> kwallace1, ?
[03:44:34] <kwallace1> LinuxCNC and the 5i22 is your controller, you need amps for brushed motors, such as the Pico or Mesa PWM amps.
[03:45:42] <kwallace1> http://pico-systems.com/pwmservo.html
[03:46:37] <pcw_home> a 5I22 is probably overkill for almost any CNC application
[03:47:53] <pzpz> pcw_home, take a look
http://pastebin.com/zMcBVz1B
[03:50:20] <kwallace1> My take on it is, 8 pwm signals with encoders, the rest is simple GPIO.

[04:01:41] <kwallace1> 2kWatts is about 2.5 hp, kind of overkill.
[04:02:27] <pzpz> 3400W motor!?!
[04:02:48] <pzpz> yes it is over kill...
[04:03:23] <pzpz> errrr i need to buy it and use torqe meter
[04:04:59] <pzpz> i need to select the PWM amps by the Continuous Current or the Peak Current??
[04:05:10] <pcw_home> Peak
[04:05:20] <kwallace1> The motor is around 700 Watts
[04:05:30] <MacGarage> realized they all work. just dont have enough strength to pull up the z axis all the way
[04:06:06] <kwallace1> No up on the Z axis?
[04:06:14] <MacGarage> its there
[04:06:18] <MacGarage> and I tested the button
[04:06:39] <MacGarage> but between the wieght and the old cold grease, I cannot left the z axis all the way to the limit
[04:07:10] <pzpz> MacGarage, what machine you have?
[04:07:18] <MacGarage> benchman xt
[04:08:03] <kwallace1> The Benchman is what you need pzpz.
[04:08:04] <MacGarage> going into the house to take a break. after getting on my knees in the garage, my back hurts!
[04:10:15] <pzpz> OMG it is looook soooo sweeeeet
[04:10:20] <MacGalempsy> thanks
[04:10:46] <MacGalempsy> the wiring has been a bugger, but i know what everything should do, so now its just interface time
[04:10:53] <kwallace1> I think this is it?

[04:11:52] <MacGalempsy> mine is the 2HP, 4th axis and 20 tool atc
[04:11:53] <pzpz> more then 3 time then what i want to spand...
[04:12:06] <MacGalempsy> i ended up giving him 5
[04:12:36] <MacGalempsy> but between shipping and tooling, we're up to 7 or 8
[04:12:49] <pzpz> and opss Net 800 lbs (363 kg)
[04:13:01] <pzpz> cant lift it..
[04:13:12] <MacGalempsy> time to hit the gym ;)
[04:13:31] <MacGalempsy> actually, I have the meat heads from the gym on call to come lift it onto the stand my uncle is welding up
[04:13:46] <pzpz> time to hit the machin with the gym....
[04:14:00] <MacGalempsy> except, he didnt finish before he went on his cruise
[04:14:09] <MacGalempsy> so now got to wait until he gets back.
[04:15:10] <pzpz> 300 Kg on old wood floor ...
[04:15:18] <pzpz> amazing..
[04:16:34] <pzpz> i will stay with the G0704...
[04:20:01] <MacGalempsy> I looked at one of those on ebay when the search was on, but after seeing this one, the precission is way better and its made in US
[04:21:30] <pzpz> but i want it as a hobby..
[04:21:49] <pzpz> not to open a factory..
[04:24:21] <jdh> quite the huge difference in price.
[04:26:15] <pzpz> yes.. 1:10
[04:27:39] <jdh> I have about $2k in my G0704
[04:28:16] <pzpz> what motor you use?
[04:28:37] <jdh> keling 540oz 23's
[04:28:51] <pzpz> stepper?
[04:28:57] <jdh> yep
[04:29:12] <jdh> cheap motors and drivers, 48v

[04:30:16] <jdh> I'd buy better ones if I did it again.
[04:31:01] <pzpz> and you covert to ball screw?
[04:31:08] <jdh> yep
[04:31:35] <pzpz> where you get them?
[04:32:00] <jdh> linearmotionbearings2008 guy chai
[04:32:18] <pzpz> ?????
[04:32:46] <pzpz> ohh i see
[04:32:56] <pzpz> ebay..
[04:33:35] <jdh> kind of. I just told him what I wanted (hoss plans) and he gave me a quote and I paid ($200 shipped)
[04:34:23] <pzpz> and it fit with the regular bearings?
[04:34:33] <pzpz> what is hoss plans?
[04:35:04] <jdh> https://www.google.com/search?q=hoss+g0704
[04:35:48] <pzpz> http://www.g0704.com/ ?
[04:35:51] <pzpz> this?
[04:35:53] <MacGalempsy> pzpz: the way I look at it is that if I can buy and industrial machine for the price of a hobby machine, why not?
[04:36:14] <RyanS> How come every time someone asks about VFDs (particularly on CNC zone), everyone says TECO... There would have to be 100 different manufacturers
[04:36:28] <jdh> teco is cheapp
[04:36:47] <RyanS> Is that it
[04:37:13] <RyanS> are Chinese ones off eBay bad?
[04:37:42] <pzpz> jdh,
http://www.g0704.com/Shop_Info.html#ballscrews
[04:37:45] <pzpz> this?
[04:38:51] <pzpz> jdh, you can tap with the G0704?
[04:38:53] <jdh> he has a set of plans for sale.
[04:39:18] <jdh> makes it really easy to do the conversion, but there is nothing you couldn't do without them.
[04:39:51] <pzpz> i'm expert in solidworks..
[04:39:53] <MacGalempsy> pzpz: the g0704 is basically a drillpress with cnc axes
[04:40:05] <MacGalempsy> so why not just use a tapping head?
[04:40:37] <jdh> tapping head is expensive and takes up a lot of Z
[04:40:44] <MacGalempsy> depending on the spindle motor, the machine may not go slow enough, or be able to reverse fast enough
[04:41:06] <pzpz> to make individual small spindle for it?
[04:42:07] <pzpz> there is a way to control the motor?
[04:42:19] <pzpz> like speed and dir..
[04:42:40] <MacGalempsy> with that machine, you would probably be best off manually tapping
[04:43:00] <MacGalempsy> or, you could run a thread mill
[04:43:24] <pzpz> what is a thread mill?
[04:43:49] <jdh> speed is easy. dir requires more
[04:44:28] <jdh> you could get a 3phase motor and a TECO VFD
[04:44:45] <MacGalempsy> im not at the point of actually machining yet, but im feeling it is close
[04:44:47] <pzpz> the motor is not universal motor
[04:44:49] <jdh> but, most of the cheap motors seem to be too heavy.
[04:44:57] <RyanS> lol, teco :p
[04:44:58] <pzpz> so you can go DC..
[04:45:05] <jdh> g0704 is a 90v dc motor
[04:45:19] <jdh> I through the teco in for you.
[04:45:26] <jdh> or threw
[04:45:44] <RyanS> Speaking of tapping do you necessarily need a capacitor brake to do it on a VFD converted drill press?
[04:46:40] <pzpz> if it is a DC the G320X not work?
[04:46:47] <pzpz> 80V 20A
[04:46:49] <RyanS> Why should it matter how quickly it reverses?
[04:48:10] <kwallace1> If you run out of turns on the tap you're out of luck.
[04:48:37] <RyanS> I don't follow
[04:48:51] <pzpz> RyanS, mee too
[04:50:21] <kwallace1> The way I see it, you spin the tap and start the hole, you stop the VFD but it doesn't slow down very quickly and you run out of turns on the tap.
[04:51:05] <RyanS> Why not just stop it earlier. Once you get used to the timing
[04:51:09] <pzpz> kwallace1, but it is not ON/OFF
[04:51:37] <pzpz> you have acceleration..
[04:52:00] <kwallace1> The VFD won't command a reverse until the motor comes to a stop.
[04:52:00] <pzpz> you need servo spidle
[04:52:25] <kwallace1> Or use a cheap resistor, works a treat.
[04:52:45] <pzpz> or use servo
[04:52:54] <RyanS> I just can't imagine tapping working very well with vfd
[04:53:10] <RyanS> how on earth do you tap Properly with a VFD if you have to reverse the quill by hand?
[04:53:36] <MacGalempsy> you dont, most vfd wont reverse fast enough
[04:53:49] <pzpz> but you can use bit for trading.
[04:54:42] <MacGalempsy> thread mill baby. they are expensive, but you can machine with a vfd
[04:55:07] <RyanS> MacGalempsy I think if you have a capacitor brake They do?
[04:55:33] -!- micges has quit [Quit: Leaving]
[04:55:33] <MacGalempsy> maybe with a brake that would work, but you would have to ask someone who has tried it
[04:55:49] <kwallace1> https://www.youtube.com/watch?v=Zxw7HaD_kxk
[04:55:52] <MacGalempsy> my machine has no brake, and to get a replacement with one would be about 2k
[04:57:16] <pzpz> https://www.datrontooling.com/index.php?_a=category&cat_id=19
[04:57:23] <kwallace1> VFD's can reverse very well, with a braking resistor and proper settings.
[04:57:38] <MacGalempsy> kwallace1: how do you get the machine to revers?
[04:57:39] <Valen> spindle synchronised motion ftw
[04:57:40] <MacGalempsy> so fast?
[04:57:44] <pzpz> regular spindle..
[04:58:16] <RyanS> I would assume, though that when the spindle reverses the tap will push the quill back up If you hold the handle loosely?
[04:58:28] <kwallace1> Within a turn at tapping speeds.
[04:58:47] <pzpz> why not use this....
https://www.datrontooling.com/index.php?_a=category&cat_id=19
[04:59:22] <MacGalempsy> pzpz look at the price of those dudes. way more expensive that an tapping head
[04:59:42] <pzpz> is datron....
[04:59:49] <RyanS> not on a drill press . You can't :)
[04:59:49] <MacGalempsy> wonder if my vfd will reverse that fast
[05:00:12] <pzpz> i send it for the shape of the bit.
[05:02:10] <RyanS> I'm thinking of upgrading froma bench drill press, and getting a three-phase drill from the start and adding vfd
[05:02:27] <RyanS> http://res3.graysonline.com/handlers/imagehandler.ashx?t=sh&id=1847922&s=gl&index=0&ts=634830121023630000
[05:02:42] <RyanS> This is the motor of the one thinking of
[05:02:55] <RyanS> 1400rpm
[05:03:03] <kwallace1> For tapping on a drill press, I would use a VFD with a dual foot peddle for forward and reverse.
[05:04:31] <pzpz> or you can tapping with a spring holder.
[05:04:56] <pzpz> and do the tapping manualy
[05:05:29] <RyanS> I suppose it isn't that much of a hassle unless you need to tap 1 million holes
[05:06:49] <RyanS> This drill press has something which sounds like is badly translated from the manual "smooth running and long lived industrial motor with frequency converter extreme engine powered, wide constant torque progression
[05:07:05] <RyanS> WTF are they talking about
[05:07:32] <RyanS> That sounds almost like a VFD
[05:08:11] <kwallace1> Actually a simple tap fixture works well:
http://www.chronos.ltd.uk/acatalog/info_41126001.html
[05:08:15] <pzpz> take it a parts.. and looking for a VFD :)
[05:08:48] <RyanS> Extreme engine that sounds hilarious
[05:09:32] <pzpz> kwallace1, you can do the same with a drill press

[05:15:40] <RyanS> I heard its pretty convenient and simple to implement tts
[05:16:30] <RyanS> But I think some people say the tools can come out during milling, but a few the owners of the machines said it wasn't a problem
[05:16:43] <pzpz> but the power drawbar look complicated..
[05:17:18] <RyanS> I don't think it is. It's just a stack of Bellville washers
[05:18:21] <RyanS> And the actuator presses down on them to open the r8 collet
[05:19:08] <pzpz> but if i make a sqweez of half a ton on the bering it can make it go wrong...
[05:20:46] <RyanS> I would guess just presses down on the collet slightly out of the tapering therefore it opens up and releases the tool
[05:22:16] <pzpz> i want to make it quiet and electric
[05:22:44] <RyanS> hmm I think electric would be easier because you don't need a compressor
[05:23:59] <kwallace1> MacGalempsy: I finally found a proper video :
https://www.youtube.com/watch?v=0qFv-TAM22U
[05:24:05] <pzpz> i dont want a compressor in the middele of my home..
[05:26:07] <pzpz> RyanS, but in tapping you need to go slooooow...
[05:28:27] <pzpz> go with 50-60 RPM and the brake will be fast.
[05:29:07] <RyanS> is 1400 rpm motor any good for a VFD?

[05:44:43] <kwallace1> During braking the VFD shorts the motor through the resistor.
[05:44:56] <MacGalempsy> oh. is that healthy for the drive?
[05:45:14] <kwallace1> and turns the braking energy into heat.
[05:45:37] <kwallace1> It's designed to do that within limits.
[05:45:38] -!- dhoovie has quit [Read error: Connection reset by peer]
[05:45:43] <MacGalempsy> maybe someday after it all works, I can try the fancy stuff :P

[05:46:21] <MacGalempsy> but right now I am on a mission to add enable and fault for each amplifier
[05:46:48] <MacGalempsy> and the zbrake power
[05:47:39] <kwallace1> If you put to much current trough the shorting transistors the brake circuit cuts out and the motor coasts to a stop with out harming anything.
[05:48:15] <RyanS> Is it simply a matter of connecting a resistor module into those terminals or do you need some fancy circuit going to the motor?
[05:48:31] <kwallace1> The Z brake is just to hold the Z while the power is off?
[05:49:19] <MacGalempsy> yes

[05:49:42] -!- dhoovie has quit [Read error: Connection reset by peer]
[05:49:48] <kwallace1> The braking resistor needs to have enough wattage and cooling to handle the braking load.
[05:50:47] <MacGalempsy> the z brake is actuated through a relay, so I need to send an out signal
[05:51:02] -!- dhoovie [dhoovie!~kvirc@122.161.181.191] has joined #linuxcnc
[05:51:26] <RyanS> If you have a, 1.5 kW motor and you need more than that for the resistor?
[05:53:29] <RyanS> *do yo, rather
[05:54:06] <kwallace1> No, it depends on how fast you want to slow the motor and how much inertia it has. Many VFD manuals have a sizing guide.
[05:56:25] <RyanS> These resistors are actually modules designed for vfds or you can simply get an off-the-shelf resistor with enough power?
[05:57:34] <kwallace1> This shows the one I made with four resistors (in gold) from Digikey:
http://www.wallacecompany.com/cnc_lathe/HNC/00024-1a.jpg
[05:58:31] <RyanS> What's the Mitsubishi thingo?
[05:59:12] <RyanS> You have two VFDS?
[05:59:49] <kwallace1> The little VFD is for the coolant pump.
[06:00:16] <MacGalempsy> kwallace1: how would I go about adding a reset that I can toggle to ground when the fault light comes one?
[06:00:17] <RyanS> This stuff would be a no-brainer for electrical engineer to install? My friend is one
[06:01:31] <kwallace1> You can also get an idea of the resistor Ohms and Wattage by using the DC bus voltage and braking transistor amperage limit. V=IR and W=VA.
[06:03:21] -!- Fox_Muldr has quit [Ping timeout: 268 seconds]
[06:03:24] <KimK> RyanS: Maybe a little explanation would be useful? Braking resistor action in a VFD (for a 3-phase motor) is a little bit different than braking resistor action for DC motors. For DC motors, you just load the motor with the resistor, the motor acts (directly) as a generator, heats the resistor, and comes to a stop.
[06:04:07] <kwallace1> MacGalempsy: I suppose a small relay or solid state relay or opto-coupler could work.

[06:05:28] <MacGalempsy> automatic reset every 200us if grounded
[06:06:27] <RyanS> I really just want variable speed. How was it ever efficient to step drill with a belt drive when you are limited to steps in speed and to do it properly, you are supposed to what... change belts 4 times for 1 hole?!
[06:06:43] <MacGalempsy> so can I set up linuxcnc to detect the fault, then completely shut down and not reset, even though the amp manually resets?
[06:07:34] <MacGalempsy> I will just try that. I think it will be easiest to get to the next point.
[06:07:47] <KimK> But in a VFD, the motor when braking acts as a generator and raises the DC bus voltage powering the three totem pole drivers (six semiconductors, be they transistors, FETs, or whatever). So if braking is desired, there must be a "seventh" transistor, to gate the braking resistor on and off the DC bus, and some control circuit to watch the DC voltage level.
[06:07:58] -!- dhoovie has quit [Ping timeout: 246 seconds]
[06:08:21] <kwallace1> You can reset the VFD from the front panel I think.
[06:08:53] <KimK> Sometimes this extra stuff is supplied with the drive, and sometimes the resistors, 7th transistor, and control circuit are all in a separate box. It depends.
[06:09:53] <KimK> s/resistors/resistor(s)/
[06:11:52] <KimK> I think step drills are a fairly recent invention. Stepped pulleys have been around for a *long* time. Since line shafts were in use, at least.
[06:12:10] <kwallace1> Fortunately, all my VFDs have had the the braking transistor built in. I think the smaller ones usually do.
[06:12:54] -!- Nekosan has quit [Quit: later folks...]
[06:13:25] <kwallace1> Often there would be a bank of drill presses, one for each operation.
[06:14:19] <KimK> Hi Kirk, good to chat with you. Yes, often the smaller ones have everything, even a minimum-sized resistor built in. With external resistor terminals in case their built-in one is too small for your application.
[06:15:58] -!- sirdancealo2 has quit [Ping timeout: 245 seconds]

[11:33:08] <jthornton> where are we at MacGalempsy ?
[11:33:36] <MacGalempsy> estop- check dro-check LIMITSWITCHES-check
[11:33:54] <jthornton> nice
[11:34:08] <MacGalempsy> got the amplifier wired up, enabled light on, but cannot get the halscope to read the waves for pid tuning
[11:34:31] <MacGalempsy> and dro has correct values btw, that was exciting
[11:34:50] <jthornton> so if you move the axis 1" the dro reads 1"
[11:35:21] <MacGalempsy> yes, i moved y the entire length and it went 12.111" and y is 7.145"
[11:35:49] <MacGalempsy> oops x=12
[11:35:56] <jthornton> did you check that the dro reads +- in the right direction for each axis
[11:36:12] <MacGalempsy> yes, all three are correct
[11:36:31] <jthornton> +X the spindle moves to the right or the table moves to the left etc
[11:37:02] <MacGalempsy> I put the table all the way to the right, and that is 0, move it all the way to the left and that is 12
[11:37:25] <MacGalempsy> push y all the way to back is 0 and all the way forward is 7
[11:37:44] <MacGalempsy> I have to check z again
[11:37:45] <jthornton> that is backwards it should be -7
[11:38:08] <jthornton> all the way up is Z0 and down is Z-
[11:38:36] <MacGalempsy> ok. working on 6am rpts. mean to get back out there in about 20

[12:12:44] <jthornton> for Y axis when the table moves back (the spindle move toward you) that is a - move
[12:13:57] <MacGarage> ok inverted the encoder from -50000 to 50000
[12:14:02] <MacGarage> its fixed

[12:16:09] <MacGarage> joint following error
[12:17:21] <jthornton> in Axis you select the axis on the Manual Control tab then press the + or - with your mouse or look at Help Quick Reference for the keyboard assignment
[12:17:23] <jthornton> s
[12:18:01] <MacGarage> when I click + the "joint 0 following error" is triggered
[12:18:51] <jthornton> you will need to loosen up the following error for the axis until you tune it
[12:19:09] <MacGarage> start with 1?
[12:20:03] <jthornton> if your working with the X axis that is AXIS_0
[12:20:17] <MacGarage> no i mean 1 for ferror
[12:20:34] <MacGarage> the other thing is, shouldnt max output be more than 1?

[12:24:57] <jthornton> looking to see what that does
[12:26:02] <jthornton> I'm not sure that is even used, comment it out and see if the config runs
[12:27:15] <archivist> have you connected the signals to drive and enable the motor
[12:27:17] <MacGarage> so I click + and the velocity goes to 5.8 but there is no movement
[12:27:56] <MacGarage> I did, when using the halmeter on the enable port, it goes to true
[12:28:02] * archivist hugs real scope to test wires and signals
[12:28:57] <jthornton> what does the analogout0 pin show when you jog?
[12:29:49] <MacGarage> 0
[12:30:31] <MacGarage> motion.enable = true
[12:32:11] <jthornton> I would think that analogout should show something when jogging
[12:32:32] <MacGarage> maybe I dont have it enabled properly
[12:32:45] <MacGarage> but the green light is on on the amplifier
[12:33:11] <MacGarage> the enable and faults on the drive are grounded, and it is powered w 70v
[12:33:22] <jthornton> what does axis.0.motor-pos-cmd show when you jog the X axis?
[12:34:02] <MacGarage> .4
[12:34:12] <MacGarage> then increases
[12:34:22] <MacGarage> I think it just needs more juice sent
[12:37:03] <jthornton> what does pid.0.output show?
[12:37:54] <MacGarage> .4
[12:38:55] <jthornton> that looks right but analogout0 should be the same...
[12:39:06] <MacGarage> they are the same
[12:39:27] <jthornton> then the axis should move
[12:39:52] <jthornton> is the axis servo holding the axis in position?
[12:40:11] <MacGarage> how would I check?
[12:40:36] <MacGarage> i can move it by hand
[12:41:33] <jthornton> if you can move it by hand when the amp is energized
[12:41:35] <MacGarage> something is backwards because I just move the x axis and the ydro readout
[12:41:51] <jthornton> yea, something wrong there
[12:42:48] <MacGarage> so the encoders are backwards

[12:47:09] <MacGarage> i have the tachs wired into the motor terminals like instructed
[12:48:30] <MacGarage> now x-amp-enable is false
[12:48:38] <MacGarage> so I need to turn that back on some how
[12:49:06] <jthornton> when you press F2 the amps should be enabled
[12:53:53] <jthornton> I can test that the config moves an axis on my BP after while
[12:54:26] <MacGarage> i saw one problem. there were two net amp-enable-out

[14:12:06] <MacGarage> let me look at the board datasheet and see if I can move some jumpers to reverse
[14:13:00] <cncbasher> hi can i help at all , just joined mid conversation
[14:15:31] <MacGalempsy> ok now there is an enable, and a pos enable
[14:15:58] <MacGalempsy> the enable enables the amplifier and can be jumped to either 5v or gnd
[14:16:05] <MacGalempsy> it is set at gnd.
[14:16:16] <MacGalempsy> the pos enable is gnd only

[14:26:37] <jdh> thanks
[14:27:28] <JT_Shop> MacGalempsy, I see what is missing in the sample config
[14:28:29] <MacGalempsy> john do you think that the enable on the amplifier needs to be grounded to enable is a problem?
[14:29:10] <JT_Shop> no, there is no amp enable in the sample config

[14:30:30] <MacGalempsy> net x-axis-enable hm2_5i25.0.7i77.0.1.analogena that is not an enable command?
[14:30:32] <PetefromTn> Morning Mac sounds like it is moving along there thats good.
[14:30:33] <Loetmichel> per: i saw -2°c this morning ;-)
[14:30:38] <Loetmichel> PetefromTn
[14:30:56] <JT_Shop> for the 7i77 card yes
[14:30:57] <PetefromTn> jdh: I'm tryin man got the house up for sale now LOL..
[14:31:04] <PetefromTn> Loetmichel: Hey man morning

[14:33:18] <jdh> then you have lots fo time!
[14:33:42] <PetefromTn> Not for a built in that is almost 20 feet long and nine feet tall I don't LOL
[14:37:01] <MacGalempsy> i am confused....
[14:38:44] <archivist> so are we
[14:38:51] <JT_Shop> your amps need an enable output and that line above turns on an output pin when you press the power button
[14:39:04] -!- thomaslindstr_m has quit [Remote host closed the connection]
[14:41:53] <MacGalempsy> but you have it coming out of the outs, and this one should be coming off the 4wire drive terminal going to the amp
[14:42:57] <JT_Shop> not sure what a 4 wire drive terminal is, but in any case I have to leave now
[14:43:31] <MacGalempsy> ena+ goes to /pos enable on the amp. the amp requires gnd to enable, or voltage/open ot inhibit
[14:43:49] <MacGalempsy> thank you for your help

[15:48:01] <pcw_home> MacGalempsy: if the drives need an active low enable (GND to enable),
[15:48:03] <pcw_home> you connect the ENA+ to the drive enable line and the ENA- to GND
[15:50:27] <pcw_home> the drive enable lines (ENA+ and ENA-) are OPTO coupler outputs (basically switches)
[15:50:29] <pcw_home> so you always need to use both (and pay attention to polarity)

[22:36:21] <WalterN> of course my screen is the only one that matters
[22:36:30] <Jymmm> That's mono, go get a shot or vga, your choice.
[22:37:33] <WalterN> hmm
[22:37:41] <WalterN> I should stuff

[22:40:40] <WalterN> no IMAPS
[22:45:01] <PetefromTn_> Well I think my $75.00 commercial wood shaper is gonna work out just fine. I managed to get it all wired back up and everything installed on the new custom built wood cabinet I made for it from an old sheet of OSB flooring material and some furniture plywood LOL.
[22:46:59] <WalterN> unless they mean IMAP includes IMAPS... not much reason to exclude it because they have SSL certs
[22:47:11] <PetefromTn_> I degreased the top and scrubbed the little rust spots off of it and it is decently smooth now. I have a tongue and groove paneling cutter to test it with but I gotta order me some new cabinet door cutters and a panel raiser cutter so I can make these doors. I know it is not as exciting as a new CNC mill or something but I am pretty happy with it. These machines are USUALLY around $2k bucks.

[23:08:32] <andypugh> I want to 3D-print a Gnu.
[23:08:54] <CaptHindsight> we need a new Gnu
[23:09:59] <CaptHindsight> "The gun is composed of 30+ 3D Printed components with 17-4 Stainless Steel and Inconel 625"
[23:10:52] <andypugh> So, it's basically a metal gun in a 3D-printed surround.

[23:13:19] <andypugh> I admit I came in late and just assumed that this was more GGG Gun-making hysteria in the media.
[23:15:42] <CaptHindsight> they left all the secondary processing steps required out of the story
[23:16:19] <andypugh> The other process I have seen included braze-impregnating it.
[23:16:53] <CaptHindsight> they only use 1 laser and layer times are in the several seconds so the total time was probably 100+ hours for all 30 parts
[23:17:42] <CaptHindsight> unless they used a larger bed and printed different parts at the same time using one printer
[23:18:09] <CaptHindsight> but all the secondary steps added several hours
[23:18:34] <CaptHindsight> they might have also secondary machined the inside of the barrel

[23:19:35] <CaptHindsight> it's mentioned but the PR is not supposed to expose the weakness of their tech, just capitalize on peoples assumptions
[23:20:09] <CaptHindsight> sorry, the secondary steps are not mentioned
[23:21:01] <jthornton> yea QCad CAM now works with points to drill holes
[23:21:18] <jthornton> I wonder how I can make it generate tapping code?
[23:21:42] <Tom_itx> jthornton does it support canned cycles?

[23:24:22] <jthornton> tapping is not a canned cycle in LinuxCNC :(
[23:24:53] <jthornton> I assume you could make it do canned cycles but why if it generates the G1 down and the G0 up
[23:25:20] <jthornton> IMHO canned cycles only help the hand programmer in most cases

[23:28:15] <andypugh> JT_Shop: Actually, tapping _is_ a canned cycle, we just don't admit to it in the docs.
[23:28:33] <Tom_itx> is it coded but not used?
[23:29:08] <CaptHindsight> http://www.kickstarter.com/projects/1638882643/diwire-the-first-desktop-wire-bender useful but overpriced
[23:29:34] <andypugh> G84 is a canned tapping cycle.

[23:29:44] <jthornton> andypugh, does it work?
[23:29:48] <andypugh> I have never tried seeing what happens if you use it.
[23:30:01] <andypugh> Maybe try it with no tap?
[23:30:19] <Tom_itx> or try tapping butter
[23:30:21] <jthornton> yea, then with soap, then with plastic
[23:30:29] <jthornton> naw, eat the butter
[23:30:43] <CaptHindsight> http://www.youtube.com/watch?v=ghDhZxidomc http://www.youtube.com/watch?v=YegMbA_lrN4 should have been kickstarter projects
