[00:24:23] <Lcvette> Jt wrote it all out for each type with an explanation
[00:24:23] <skunkworks> boy - I would think so...
[00:32:57] <Tom_L> o
[00:33:07] <Tom_L> i'll look for it tomorrow
[00:33:39] <Tom_L> just looking at one of his examples trying to see how a button ties to a hal pin
[00:34:51] <Tom_L> skunkworks i would think so too

[05:50:12] <_abc_> Hi. Has anyone booted the wheezy live 2.7 iso with qemu under linux? I booted it, it gets to gui, things work, then launching linuxcnc with a config locks it with a high system load. Completely non responsive. Is there a known qemu param set which makes it work? Any ideas where to look to make the iso work as is in emulation (sim) mode? Host is linux.

[07:17:06] <drzacek> Hello there
[07:17:41] <drzacek> I have a technical problem, not directly related to linuxcnc, but you guys are the closest thing I found on freenod :P
[07:17:56] <pink_vampire> lets see..
[07:18:34] <pink_vampire> drzacek: ?
[07:18:45] <drzacek> I need a module to control my axes on a cnc lathe. Was looking for 4x analog output -10..+10V with TTL encoder inputs.
[07:19:38] <drzacek> at first there seem to be a plethora of modules, but in the end nothing that would fit my needs - either it is not a single device only 2,3 or 4 different modules
[07:20:28] <pink_vampire> what are you trying to do?
[07:20:50] <drzacek> connect my control unit to the drive
[07:21:22] <pink_vampire> what is your controller?
[07:21:26] -!- _abc_ has quit [Read error: Connection reset by peer]
[07:21:52] <drzacek> MTc
[07:21:55] -!- _abc_ has joined #linuxcnc
[07:22:52] <drzacek> there used to be a custom hardware with integrated analog outputs and encoder inputs, but I upgraded the PC and can't use that anymore (was for ISA bus, so ancient stuff)
[07:25:25] <pink_vampire> you ,ean between the motor and the controller?
[07:25:31] <pink_vampire> mean*
[07:26:53] <drzacek> well, I have a controller, I have a siemens 611a drive that controlls the motors, and I need something to generate signals for the drive module
[07:32:27] <pink_vampire> drzacek: I'm not sure what are you asking, do you have any drawings , or something that will clear how it is wired up and what signal go to where
[07:34:13] <pink_vampire> as far as i know there is converters from 0-10V to 4-20ma, and stuff like that
[07:34:23] <drzacek> pink_vampire, well, there are
[07:34:24] -!- c-log has quit [Ping timeout: 244 seconds]
[07:34:56] <drzacek> but currently the only option would be to buy a modular I/O module (like et200 from siemens), and put 4 such converters on it
[07:35:16] <drzacek> well, 3, since I only have 3 axes
[07:36:23] <drzacek> my controller is a normal PC (in a compact form), with USB/Profibus/Profinet as possible connections, and I need to have a module that will generate me 0-10V analog signal for the drive
[07:37:20] <drzacek> well, I was googling for a while and couldn't find anything that would work for me (and doesn't cost 3000 euro), was just a desperate try to ask here, but don't know how you guys connect your motors to your pc
[07:37:40] -!- c-log has joined #linuxcnc
[07:37:40] -!- c-log has quit [Changing host]
[07:37:40] -!- c-log has joined #linuxcnc
[07:37:53] <drzacek> what I'm asking is rather purely industrial, not sure if any linux cnc machine even has something else as stepper motors
[07:38:18] <pink_vampire> myservos works with the g320X
[07:38:33] <pink_vampire> it is a dc servos
[07:39:09] <pink_vampire> so you have the pc > g320X >encoder > motor
[07:39:34] <pink_vampire> linux cnc give you step and direction signals
[07:39:59] <pink_vampire> but i know that you can control also more complex stuff
[07:40:38] <drzacek> well I never touched the linux cnc, just downloading it now to see what it really does
[07:41:19] <pink_vampire> to generate 0-10 it is much more easy then -10 .. +10
[07:42:04] <drzacek> well
[07:42:10] <pink_vampire> linuxcnc is just the controller
[07:42:12] <drzacek> I neeed -10..+10
[07:42:31] <drzacek> well, yes, but what can it controll :)
[07:42:33] <pink_vampire> what you motor driver need as input?
[07:43:02] <drzacek> 0..10V as speed value, in both directions, so -10 to 10V
[07:43:23] <drzacek> on two wire lines, gnd and value
[07:43:49] <pink_vampire> so you need a step dir to +-10V
[07:45:22] <pink_vampire> the acceleration values in linux cnc are +- some value
[07:45:25] <pink_vampire> so this is a start
[07:48:35] <pink_vampire> https://www.youtube.com
[07:49:04] <pink_vampire> drzacek: look like something you can do
[07:52:25] <pink_vampire> https://www.eevblog.com
[07:53:21] <_abc_> 10V servos are not too good in precision, expect 0.1% or worse, after calibration.
[07:54:23] <drzacek> _abc_, I have no servos
[07:54:23] <_abc_> A normal digital to 10V servo controller will have some decent amount of settings in it to mate it to the encoders and the servo's actual driver.
[07:54:38] <_abc_> Just speed?
[07:54:58] <drzacek> I already have the motor controller, that takes the 10V as speed value
[07:55:01] <_abc_> There will have to be an enable too, or a sizeable deadband.
[07:55:15] <pink_vampire> _abc_: he also want to connect encoders
[07:55:25] <_abc_> oh that gets complex fast
[07:55:26] <drzacek> wait, I'll make some pictures
[07:55:36] <_abc_> drzacek: we get the point.
[07:55:46] <_abc_> pink_vampire: encoders for distance or speed?
[07:56:17] <pink_vampire> _abc_: not sure what do you mean by that
[07:56:56] <_abc_> speed encoders on a spindle or distance ones for angular motion like on a lathe with less than 360 degrees turn for special jobs?
[07:58:00] <drzacek> ttl incremental encoders
[07:58:04] <drzacek> no absolute encoders
[07:58:47] <pink_vampire> what resolution?
[08:00:38] <drzacek> irrelevant
[08:01:01] <drzacek> https://pasteboard.co this is what I had till now
[08:01:35] <drzacek> and ideally I would like to have something like this as USB module
[08:03:27] <pink_vampire> the thing that i don't get it how you close loop with the encoder, is that in the controller level? or the motor driver level?
[08:03:40] <_abc_> drzacek: usb has no timing guarantees. Nothing realtime tries to use usb as a part in the realtime pipe.
[08:04:02] <drzacek> controller does it
[08:04:15] <drzacek> _abc_, ideally I would use profinet
[08:04:18] <_abc_> The controller has smarts in it, it's not just usb timing controlled
[08:04:30] <_abc_> Double buffering etc
[08:04:33] <_abc_> FIFO

[09:10:07] <burkelfoo> drzacek: take a look at our (Mesa's) 7I77/7I77D + a 5I25 or 7I92M for analog servo retrofits
[09:12:18] <pink_vampire> what will be a good mesa cards replacement to dual lpt setup?
[09:12:28] <pink_vampire> burkelfoo: ^
[09:12:50] <burkelfoo> 5I25 (PCI) 6I25 (PCIE) or 7I92H (Ethernet)
[09:13:58] <pink_vampire> is there and advantage / disadvantage?
[09:18:46] <pink_vampire> burkelfoo: ?
[09:19:13] <gregcnc> pink have you checked the specs?
[09:19:55] <pcw_home> you choose between 5I25/6I25 by slot availability in your PC
[09:20:43] <pink_vampire> i mean Ethernet V PCI/e
[09:20:51] <pcw_home> Ethernet is a bit harder to setup and requires the uspace version of LinuxCNC
[09:20:53] <pink_vampire> vs*
[09:21:39] <pcw_home> but doesn't require a slot and is handy to mount in the enclosure
[09:23:00] <pink_vampire> i want to get a smaller computer then the one i have now, and fit a pcie card in it, and fit all that in the bottom side of my panel
[09:23:09] <pcw_home> if you have something exotic to control that needs a fast servo thread (faster than 1 KHz) PCI/PCIE is better
[09:24:17] <gregcnc> pink are you planning on replacing your Geckos? and closing the loop in linuxcnc?
[09:24:53] <pcw_home> but at the default 1 KHz, Ethernet is fine and has the added benefit of electrical isolation and the ability to work with mini-pcs that have no slots
[09:25:34] <pink_vampire> now i'm limited to 100000 ns (i was tried to go to 50000ns, but i got the realtime error all the time, so my servo spindle, is very slow, 100 rpm :(
[09:26:06] <pcw_home> thats the base thread, its not used with our hardware
[09:26:22] <pink_vampire> gregcnc: not right away, but yeah, maybe to leave the g320X, but add scales
[09:27:22] <pink_vampire> not sure what do you mean
[09:28:29] <pink_vampire> i want to be able to use the full speed of the motors, with the full resolution of the encoders
[09:29:02] <pink_vampire> 4 motors, 3000rpm each, 8192PPR encoders
[09:29:32] <gregcnc> with mesa it will run much faster without changing the PC
[09:31:16] <pcw_home> 8192 PPR or 8192 CPR? (8192 PPR = 32768 CPR = higher than most incremental encoders)
[09:33:30] <pink_vampire> PPR
[09:33:35] <pink_vampire> 2048PPQ
[09:33:35] <pcw_home> with Mesa (or other hardware stepgens), the step rate is independent of the thread rate
[09:34:15] <pink_vampire> what is the thread rate?
[09:34:32] <pcw_home> the rate at which the step rate is _updated_ is the servo thread rate (normally 1000 times a second)
[09:35:13] <pcw_home> on your parallel port setup you have two threads running (base thread and servo thread)
[09:35:20] <sensille> so the mesa card doesn't get any motion profiles in advance?
[09:35:54] <pcw_home> sensille: no, linuxCNC doesn't work that way
[09:37:40] <pcw_home> pink_vampire: with a hardware stepgen (encoder counter pwmgen etc) the base thread is not needed anymore so only the (much slower) servo thread is run
[09:39:42] <pink_vampire> one sec - phone call

[09:44:15] <gregcnc> I don't think it's clearly defined to newbs as latency test appears to be so important
[09:44:21] -!- HSD has joined #linuxcnc
[09:45:12] <sensille> would it be worth it to put more effort into more exact step generation, e.g. by tranferring motion profiles, or is there not much to gain?
[09:50:01] <pcw_home> Not much to gain if you can run the TP in LinuxCNC at 1 KHz
[09:51:46] <pcw_home> if you have extreme accuracy requirements or very high acceleration, moving acceleration setting to the stepgen may make sense
[09:54:34] <pcw_home> but the chord error from stepped velocities is in the 10 uinch (.25 u) on the types of machines LinuxCNC normally runs so buried in the noise...
[09:54:55] <pcw_home> 10 uinch range
[09:55:09] <sensille> yeah, maybe just for better acceleration/jerk control
[09:55:57] <pcw_home> LinuxCNC doesn't have Jerk control currently, thats really something the TP needs to do
[09:57:01] <pcw_home> Jerk control would be nice but its quite complex to integrate with a complete TP
[09:57:36] <sensille> what does TP stand for?
[09:57:48] <pcw_home> Trajectory Planner
[09:57:55] <sensille> ah
[09:57:59] <Jymmm> Toilet Paper
[09:58:51] <gregcnc> Jymmm is always here to help
[09:58:52] <sensille> i'm currently working on smooth motion planning for a 3d printer controller and find it very interesting, but also challaeging
[09:59:15] <pcw_home> Jerk control is nice for tangential acceleration but doesn't really help with constant speed profiling
[09:59:16] -!- ziper has joined #linuxcnc
[09:59:19] <Jymmm> gregcnc: ...or hinder -shrug-
[10:00:11] <sensille> it gets hard if you want to allow path deviation
[10:00:18] <pcw_home> (because the jerk is entirely controlled by the shape)
[10:01:19] <Jymmm> pcw_home: define "jerk" in this context of shape?
[10:02:01] <sensille> it's also defined by velocity/acceleration, but given a constant speed only by the shape
[10:02:19] <pcw_home> if you follow a profile at a constant speed the acceleration and jerk are determined by the shape you follow
[10:02:42] <Jymmm> pcw_home: like a hard corner (of sorts)?
[10:02:51] <pcw_home> any shape
[10:02:57] <sensille> or a transition between line and circle
[10:03:35] <Jymmm> pcw_home: I thought there was a ramp down/ramp up when there is a sudden change in direction?
[10:03:51] <sensille> pcw_home: did you work on the TP?
[10:04:35] <Jymmm> pcw_home: ...a "look ahead" if you will.
[10:04:40] <pcw_home> there is if you cannot maintain velocity due to accel limits
[10:04:55] <Jymmm> ah ok
[10:06:10] <pcw_home> No, I have not even really looked at LinuxCNCs TP (other than testing and reporting bugs)
[10:06:58] <sensille> pcw_home: i'm still looking for someone with whom i can discuss my ideas from time to time, so i got my hopes up a bit ;)

[10:34:52] <pink_vampire> I'm here again
[10:34:55] <Lcvette> pcw_home: i snagged another H97M Pro4 but it had a Core I5 4590 3.3GHz cpu on it, im hoping it will have similar performance to the G3258, did by chance have any experience with those did you?
[10:42:13] <drzacek> burkelfoo, no way that I could use those in my current hardware
[10:53:55] <pink_vampire> I'm trying to think what will better to upgrade next, the rails and the ball nuts, or move to mesa cards
[11:00:44] <pcw_home> drzacek: I thought you said you wanted to control Analog servos (and I assumed with LinuxCNC)
[11:01:54] <drzacek> pcw_home, no, it's not with linuxcnc, and not servos (although if servos are controlled with -10..10V signal then I'm ok with that)
[11:02:25] <drzacek> I just need some module for my PC that will deliver those, and get encoder input too
[11:03:09] -!- jerryq has joined #linuxcnc
[11:15:50] <gregcnc> drzacek "some module" must be able to communicate with your software
[11:16:49] <drzacek> gregcnc, that would be nice, yes
[11:16:59] <gregcnc> what is this machine?
[11:17:10] <drzacek> ?
[11:17:11] <gregcnc> what software does it run?
[11:17:21] <drzacek> my own
[11:17:33] <gregcnc> your own software?
[11:17:57] -!- Inline has joined #linuxcnc
[11:17:57] <drzacek> yeah, we did our own lathe software
[11:18:07] -!- P1ersson has quit [Ping timeout: 240 seconds]
[11:18:15] <drzacek> nothing too fancy
[11:18:18] <gregcnc> based on what? anything existing?
[11:18:27] <drzacek> not that I know
[11:18:32] -!- fdarling has quit [Ping timeout: 250 seconds]
[11:19:00] <gregcnc> so why not just replace what failed?
[11:19:07] <drzacek> but I have full access to the code, so if I need to I can write proper communication with the the module
[11:19:17] <drzacek> gregcnc, cause it's not something that failed
[11:19:37] <drzacek> after 20 years time to change hardware
[11:19:44] <drzacek> and new pc don't have any ISA bus anymore
[11:22:29] <gregcnc> OK the actual problem is defined now, but I can't help. probably there are countless solutions like Mesa to connect via PCI or ethernet and do what you want
[11:23:05] <drzacek> okay
[11:23:41] <gregcnc> If you aren't going to use linuxcnc to control your machine, it's not relevant
[11:24:34] <gregcnc> I dread the day the ISA card or related control dies in my PC based lathe
[11:25:58] <drzacek> well, ISA was very popular in industrial systems. My first pc from 99 never had any ISA connector anymore, it was already too old, I can imagine that 20 years later it is even worse, even in industry world
[11:26:25] <drzacek> the future is real time ethernet, like profinet
[11:26:51] <drzacek> but throwind away analog drives and replacing them with new ones - aint nobody got money for that
[11:26:58] <gregcnc> apparently you can still get them, but this machine is particular is extremely picky and nobody has made a newer motherboard work
[11:27:08] <gregcnc> ISA that is
[11:27:09] <drzacek> what do you have?
[11:27:35] <gregcnc> smaller Emco lathe and mill
[11:28:15] <gregcnc> the mill i'd just retrofit to Linuxcnc, but the lathe I would rather keep on the Fanuc emulated control
[11:28:30] <drzacek> is it ona mainboard or slot cpu?
[11:28:37] <drzacek> *on
[11:29:00] <gregcnc> windows PC with a ISA card to comm with their control

[14:24:41] <miss0r> evening
[14:25:37] -!- zkrx has quit [Quit: I'm done]
[14:26:53] <JT-Shop> hola
[14:28:06] * miss0r is using his poorly ventilated shop to paint engine parts for the land rover at the moment
[14:28:12] <miss0r> so, if I don't make sense, that is why :D
[14:28:39] -!- zkrx has joined #linuxcnc
[14:29:33] <miss0r> if fragalot was here, he would say something like "so whats your excuse the other days?"
[14:29:34] <miss0r> :D
[14:29:55] <fragalot> no I wouldn't
[14:30:16] <miss0r> hehe hello
[14:30:23] <fragalot> 'sup :-)
[14:30:29] <miss0r> Don't try'n tell me you would take the high-road?! :D hahaha
[14:30:54] <fragalot> I wouldn't dare.
[14:31:11] <Rab> miss0r, use a good respirator.
[14:31:28] <fragalot> and lead based paints for taste
[14:31:31] <miss0r> rab: I have the door open, and the ventilation running - it should be alright
[14:32:00] <miss0r> fragalot: Friday I have to go look at an Emco cnc lathe
[14:32:09] <fragalot> same :D
[14:32:16] <fragalot> except I believe i've got a different reason to than you?
[14:32:31] <miss0r> I just saw a cheap one, and I want to own it? :D
[14:32:35] <miss0r> whats yours
[14:32:49] <fragalot> to try & convince someone else to pay for it
[14:33:17] <miss0r> I found a emco TM02 for 2200eur..
[14:33:23] <miss0r> hehe I think I'll do this one myself
[14:33:36] <fragalot> :-)
[14:33:39] <gregcnc> VMC100?
[14:33:49] <miss0r> I'll bring my dial indicators and sweat him down to 1200eur I think
[14:34:13] <miss0r> gregcnc: No. This is an '80s model
[14:34:22] <gregcnc> TM02 is the control
[14:34:22] <miss0r> Do I look like I am made of money?
[14:34:23] <fragalot> don't forget the py bar :P
[14:34:29] <fragalot> pry
[14:34:41] <miss0r> yeah sorry :D its a compact 6
[14:34:50] <gregcnc> oh I have on of those
[14:34:56] <miss0r> You like it?
[14:35:03] <miss0r> (I have no idea how to run the controls on it)
[14:35:13] <gregcnc> pfft still not finished with retrofit

[14:35:33] -!- EntropyWizard has joined #linuxcnc
[14:35:39] <gregcnc> biggest thing I think if it has any time on it is the fact that they didn't have automatic lube
[14:35:47] <miss0r> fragalot: It was situated in a school in sweden, pro: low mileage. con: those few miles was in rough terrain :D
[14:36:13] <gregcnc> with pneumatics?
[14:36:26] <miss0r> I honnestly know very little of the model
[14:36:35] <miss0r> and the article doesn't say alot
[14:36:35] <gregcnc> 6P?
[14:36:35] <fragalot> ¨lol
[14:36:48] <miss0r> gregcnc: https://www.dba.dk
[14:37:15] <miss0r> also, it comes with a cassete tape to restore the machine configuration :]
[14:37:16] <gregcnc> no pneumatics
[14:37:17] <fragalot> that control looks lovely and very user friendly

[14:37:39] <fragalot> miss0r: have the labels worn off of it yet? :D
[14:37:53] <fragalot> (off of the buttons)
[14:38:01] <miss0r> fragalot: To a degree where I am unsure if there ever was any :D
[14:38:15] <fragalot> excellent :D
[14:38:32] -!- Tom_dev has joined #linuxcnc
[14:38:33] <gregcnc> small ~16mm through spindle, odd 5phase steppers, DC shunt wound spindle motor
[14:38:46] <miss0r> sounds like a charm
[14:39:08] <fragalot> miss0r: if you don't mind me asking
[14:39:09] <miss0r> gregcnc: Would you care to guess at the rough dimensions of the machine?
[14:39:15] <fragalot> where the hell are you going to put that chonk
[14:39:33] <gregcnc> just a minute
[14:39:35] <miss0r> I was just about to tell you "I DON'T KNOW" as I knew that question was comming
[14:39:46] <fragalot> :D
[14:40:06] <miss0r> I am in the process of getting a permit to place a 20' shipping container in my frontyard, next to the shop
[14:40:21] <miss0r> and put all my grinding equipment, the saw & all materials in that
[14:40:28] <miss0r> (insulated with heat)
[14:40:32] <fragalot> nice
[14:41:05] <miss0r> assuming gregcnc returns with "size < elephant" I think I could pull it off
[14:41:22] <gregcnc> lathe is 1035x853x750 control box 810x745x715
[14:41:38] <gregcnc> it's small if you've never seen one
[14:41:39] <miss0r> in mm, I presume?
[14:41:49] <miss0r> anything else would be hell :D
[14:42:03] <miss0r> I've never seen a compact 6 in person, no
[14:42:15] <gregcnc> lathe is 225kg control 115
[14:42:20] -!- Dave_Elec has quit [Ping timeout: 250 seconds]
[14:42:23] <fragalot> that is a lot lighter than i'd have imagined
[14:42:26] <miss0r> wow that is light
[14:42:32] <gregcnc> they are small
[14:42:43] <miss0r> damn... can it even cut butter?
[14:42:52] <miss0r> at room temperature?
[14:43:10] <miss0r> 225kg sounds on the light side of ridiculous
[14:43:29] * miss0r is starting to have second thoughts about this lathe
[14:43:36] <fragalot> :P
[14:43:53] <gregcnc> 2.2kW motor maybe 4kW peak
[14:43:54] <miss0r> Sure, I have a manual lathe for the hard work.. but still
[14:43:57] <fragalot> it'd be better than my dinky chinaco lathe, barely
[14:44:06] <miss0r> what spindle speed does it do?
[14:44:10] <gregcnc> they have good reputation
[14:44:17] <gregcnc> 4 or 5kRPM
[14:44:20] <miss0r> hmm
[14:44:25] <miss0r> I wonder how rigid it is
[14:44:25] -!- fdarling has joined #linuxcnc
[14:44:29] <miss0r> I know they have a great rep
[14:44:31] <fragalot> 5K rpm but with a chuck rated for 3 :D
[14:44:50] <miss0r> fragalot: keep your lathe out of it :P
[14:44:55] <fragalot> hehe
[14:45:11] <gregcnc> compact 6 would have been 4k
[14:45:26] <miss0r> gregcnc: How would you describe its ability do machine steel?
[14:45:31] <gregcnc> the later 120, 220, and 320 were all based on the same casting
[14:45:34] <miss0r> Most of what I do is 42CrMo4
[14:46:10] <gregcnc> to me the bigger question is work holding in the chuck
[14:46:44] <miss0r> the spindle bore is small.. but I suppose the chuck can hold 80mm ish?
[14:47:19] <gregcnc> how long are these parts?
[14:47:32] <miss0r> mostly <300mm
[14:47:35] <miss0r> 250 even
[14:48:07] <gregcnc> you'de really have to study the work envelope tp be sure
[14:48:11] <miss0r> Indeed
[14:48:22] <miss0r> but for that price I'm sure I can put it to work and make my money back :D
[14:48:42] <miss0r> if not, it would make a cool greenhouse
[14:48:56] <gregcnc> the 220 and 320 were mostly used with a collet chuck and 26mm through the spindle
[14:49:09] -!- zkrx has quit [Quit: I'm done]
[14:49:45] <miss0r> Hmm.. I wonder if theres any additional equipment with this unit(collets, tool holders ect)
[14:50:01] <miss0r> is that a turret in there?
[14:50:27] -!- Tom_dev has quit [Remote host closed the connection]
[14:50:48] <gloops> nice little lathe here https://www.ebay.co.uk
[14:51:20] <gloops> 8metres, 30hp
[14:51:31] <gregcnc> I have a more recent 325-II, with a 4.4kW spindle and in can barely run a 2.2mm grooving insert in that material at 28-32HRC and Ø2"

[14:52:50] <fragalot> that thing is kinda cute
[14:53:47] <miss0r> gregcnc: So, you reused the casting, basically? :D
[14:54:11] -!- Dave_Elec has joined #linuxcnc
[14:54:20] <gregcnc> it had not control, I'm changing all motors
[14:55:05] <gregcnc> not me https://youtu.be
[14:56:32] <gregcnc> I have all the sheet metal for the enclosure. I stripped it completely to clean and probably removed 2-3kg of old oil and chips
[14:56:49] <miss0r> sounds yummy
[14:57:12] -!- _abc_ has joined #linuxcnc
[14:57:12] <fragalot> that broach sounds like it's not even hitting
[14:58:18] <fragalot> parting sounds alright on that one too
[14:59:01] <miss0r> yeah
[14:59:14] <miss0r> the parting sounds like the broach did 'something' atleast
[14:59:33] <fragalot> it shows what it did at the end of the video, so it definitely did :-)
[14:59:39] <Tom_L> JT-Shop you ever try setting up dual monitors with stretch?
[14:59:51] -!- zkrx has quit [Quit: I'm done]
[15:00:07] <miss0r> fragalot: I got a new saw blade for my cold saw
[15:00:21] <miss0r> Now I don't want to hang myself everytime I cut larger workpieces
[15:00:27] <jthornton> no, I looked at one motherboard and it does not support dual monitors without a windoze driver
[15:00:30] <fragalot> miss0r: :D
[15:00:32] <gregcnc> if it doesn't have collet chucks, you'll probably never find one
[15:00:43] <miss0r> its a 350mm blade with 63 teeth
[15:00:59] <fragalot> miss0r: at my previous work where I ran one of those saws daily, it would never make it past 5 days
[15:01:02] <Tom_L> i've got a cheap add in card that works with windows but the aspect ratio is off with stretch
[15:01:03] <miss0r> I thought the salesman made a mistake and sold me a wood cutting blade. sure looks like it
[15:01:12] <fragalot> i'd install a new blade on monday, and someone would wreck it in the weekend
[15:01:21] <Tom_L> installing the dev stuff on my main pc
[15:01:28] <miss0r> Yeah, luckily I'm the only one using it here
[15:01:30] <miss0r> :D
[15:01:33] <fragalot> :P

[15:03:02] <miss0r> I wouldn't mind finding a emco cnc lathe that is a bit newer, so it had the heidenhain controller on it
[15:03:09] <miss0r> I know a wizard with those controllers
[15:03:30] <miss0r> its not me; i'm not boasting here...
[15:04:01] <fragalot> apparently the heidenhain lathe controllers are dogshit compared to the milling ones
[15:04:16] <fragalot> i'm currently eyeing up a hyperturn 65
[15:04:34] <miss0r> I wonder if that is also true about the older ones?
[15:04:41] <fragalot> hyperturn 65 DT SM3Y3
[15:04:53] <gregcnc> 2 axis lathe programming is easy
[15:04:54] <miss0r> o_0
[15:05:07] <miss0r> looks nice
[15:05:09] <fragalot> miss0r: yea, heidenhain just bought the lathe controls from a different company, forgot which though

[15:06:10] <miss0r> no no... theres a bit more comming

[15:09:29] <gregcnc> just in case the night shaft crashes it?

[15:09:45] <miss0r> gregcnc: Are you speaking of a porno movie there?
[15:10:07] <gregcnc> it will have a harder time crashing itself if nobdoy is there to fuck with it
[15:10:14] <fragalot> :-)
[15:10:17] <fragalot> gregcnc: that's the idea
[15:10:37] <fragalot> tools will all be equipped with balluff RFID tags with the offsets pre-set to avoid operator error there too
[15:10:49] <fragalot> and they are continuously monitored in use to see if the loads and vibrations are in-spec
[15:10:59] <miss0r> Those expensive machines.. :) Last week I was home waiting for a taxi driving here direct from Hamburg, Germany with three inductive switches so I could get a spindle going

[15:21:52] <pink_vampire> is there already made bipod kinematics?machine profile?
[15:22:08] <miss0r> I mean, don't you have a garden to tend to?
[15:22:19] <miss0r> (perhaps you have reduced it to grass that needs removing?)
[15:22:27] <fragalot> grass & wood chips
[15:22:32] <fragalot> everything just goes in buckets in the back
[15:23:08] <miss0r> beeing a green fellah' like you are, I suppose you skip the disposible plastic bags, and have the woodchipper spew it directly into the trunk? :D
[15:23:43] <fragalot> "buckets"
[15:23:48] <miss0r> meh.. You have it easy. My garden still pretty wild - though I have been doing something to it lately
[15:23:56] <miss0r> yeah yeah.. I was typing when you wrote that
[15:23:57] <fragalot> well i felled the pear tree the other day
[15:24:01] <fragalot> dug out the stump last weekend
[15:24:14] <fragalot> that's the last of the big trees
[15:24:22] <fragalot> the rest are just 60yr old bushes
[15:24:22] <miss0r> "big" hehe
[15:24:31] <fragalot> yea :-)
[15:24:56] <miss0r> I've been draping the "hill" in the frontyard in this sorta fiber tarp
[15:25:04] <fragalot> only had 2 trees, one 65yr old pear tree that nearly rached the roof of the house, and an 80yr old pine that exceeded it by about twice that
[15:25:09] <miss0r> to keep undergrowth down, and covered it in woodchips
[15:25:19] <fragalot> i've done that, once.
[15:25:27] <fragalot> turns out it's a breeding ground for snails
[15:25:30] <fragalot> :P
[15:25:32] <miss0r> all it took ? or never doing it again? :D
[15:25:37] <miss0r> lol fuck
[15:25:43] <miss0r> like I don't have enough of those
[15:26:26] <miss0r> you serious?
[15:26:32] <fragalot> yea
[15:26:40] <miss0r> and what kind of fabric did you use?

[15:26:58] * miss0r screams to the heavens
[15:27:02] <miss0r> same exact stuff I have

[15:27:45] <miss0r> I fscking hope it is not going to be a big issue here
[15:28:01] <miss0r> I mean.. the area I did it to is 25x10meters ish
[15:28:07] <miss0r> perhaps closer to 30x12
[15:28:21] <fragalot> mine was 1.5x6
[15:28:22] <miss0r> and its pretty steep. not a trivial task
[15:28:27] <fragalot> and flat
[15:28:43] <fragalot> your experience may vary
[15:28:49] <fragalot> I hope
[15:28:55] <miss0r> This better be good
[15:29:17] <fragalot> I did figure out though that if you lob a snail at least 30 meters away, it doesn't come back
[15:29:34] <miss0r> Well, I did it because the undergrowth on that slanted surface was a nice resting place for mosquitos... and I'm realy trying to combat that.. I guess I'll take snails over mosquitos any day

[15:32:33] <miss0r> regulations with that stuff is realy strict here in DK
[15:32:40] <miss0r> I wouldn't mind having one though..
[15:32:48] <fragalot> there is only one rule in belgium for airguns
[15:32:55] <fragalot> pistols are limited to 7.5J
[15:32:57] <fragalot> that's it.
[15:32:59] <miss0r> "you can't own one" ? :)

[15:33:24] <miss0r> 7.5... I could throw the pebble further

[15:33:43] <fragalot> go nuts
[15:33:52] <miss0r> re-he-he-he-healy?
[15:34:05] <fragalot> as long as it is over 30cm in length

[15:35:10] <fragalot> not that powerful, but that thing fires under 20mm groups at 100m
[15:35:33] <miss0r> sweet
[15:36:58] <fragalot> i've got quite a few, all are fun in their own way
[15:37:19] <fragalot> diana 56th, just interesting design & kills every single scope you put near it
[15:37:28] <fragalot> except with a zero recoil mount
[15:38:05] <fragalot> walther LGU, also an interesting design
[15:38:05] <miss0r> nice
[15:38:21] <fragalot> had another one I sold that I can't remember the make of
[15:38:42] <fragalot> stomped like a mule & made very nice patterns if the target wasn't too far away.. if it was it wouldn't make any form of pattern
[15:39:18] <fragalot> some russian target pistol, and a walther CP99
[15:39:31] <fragalot> the last one I want to get rid of but can't sell it online due to legal reasons
[15:39:42] <fragalot> lots of dutchies interested in it, but also can't sell it to them for legal reasons

[16:07:29] <roycroft> any welding folks alive?
[16:07:35] <roycroft> i need a sanity check on some settings
[16:08:01] <roycroft> teh internet are all over the place on recommendations, and i want my settings to be close enough from the start that i just have to do a bit of dialing in
[16:10:18] <roycroft> i'll be gtaw welding 3/8" (8mm) mild steel, mostly right angle welds
[16:10:49] <roycroft> i have 1/8" (3mm) 2% lanthenated electrodes, and 1/8" er70s-2 rods
[16:11:03] <roycroft> i'll be doing dcen
[16:11:15] <roycroft> i'm seeing recommenations for that from 80a to 250a
[16:11:21] <roycroft> which is hugely wide range
[16:12:16] <roycroft> i'd also like to do some pulsing, to help keep warping down, but some folks say that works fine and some say that i won't get good welds unless it's full power all the time
[16:13:23] -!- sumpfralle has quit [Ping timeout: 245 seconds]
[16:13:34] <roycroft> i've never gtaw welded mild steel before, and aluminium and stainless steel only a few times
[16:13:38] -!- _abc_ has joined #linuxcnc
[16:13:53] <roycroft> it kind of sucks - my welder is about 7 years old now, and i only have a handful of hours on it
[16:13:55] <methods_> why not just go at 250 and watch your foot
[16:14:07] <methods_> or do you not have a pedal?
[16:14:10] <roycroft> i do
[16:14:34] <roycroft> i'm not all that coordinated though (i can be, but i haven't spent much time on it)
[16:14:57] <roycroft> left and right hand together is enough to coordinate without getting the foot involved too :)
[16:15:16] <roycroft> i've been successful with a long ramp up/down time and just using the switch on the torch in 2t mode
[16:15:24] <roycroft> more successful doing that than trying to use the pedal
[16:15:37] <roycroft> i really just need to spend a couple days making beads, i know
[16:16:23] <roycroft> i have a friend who is a really experienced welder, and he hates pedals
[16:16:31] <methods_> well it's about like stainless it's not bad
[16:16:40] <methods_> its definitely not as difficult as alum
[16:16:42] <roycroft> he has torches with dials on them so he can adjust the current on the torch
[16:16:44] <roycroft> which is nice
[16:16:50] <methods_> and even alum isn't that bad once you spend some time under the hood
[16:16:52] <roycroft> i found aluminium to be pretty easy to weld
[16:17:04] <methods_> yeah i don't like the thumb switch
[16:17:25] <methods_> i know a lot of people like the thumb especially guys that weld inside of stuff alot
[16:17:25] <roycroft> unfortunately my friend is out of town, or he would probably be able to tell me exactly how to set it up
[16:17:40] <methods_> since you really can't put a pedal down inside a tank with you alot of times
[16:17:48] <roycroft> yeah, that can be tough
[16:17:49] <methods_> or inside a boiler or soemthing
[16:17:57] <roycroft> that's the big problem with a pedal
[16:18:05] <roycroft> and i know i can use a pedal if i spend a little time with it
[16:18:17] <roycroft> but i'm in a mode, again, where i just want to get some welding done
[16:18:17] <methods_> which is not a problem for me since i don't weld inside stuff like that
[16:18:36] <methods_> it's well worth it to get used to using it
[16:18:41] <roycroft> so what about pulsing to keep the warping down?
[16:18:51] <roycroft> i don't know if i should bother with that or not
[16:19:06] <methods_> well mild doesn't warp like stainless so usually i dont worry about it
[16:19:20] <roycroft> and it's fairly thick
[16:19:29] <roycroft> that's my real concern
[16:19:30] <methods_> and with stainless i just take my time
[16:19:38] <methods_> 3/8 isn't that thick
[16:19:43] <roycroft> if i pulse i might not be able to put enough heat on the metal for good penetration
[16:19:50] <roycroft> compared to what i usually weld it is
[16:19:51] <methods_> but that's why i'd go at 250a
[16:19:55] <roycroft> and it may be pushing the limits of my welder
[16:20:01] <roycroft> which maxes out at 250a
[16:20:04] <methods_> that may be the case
[16:20:09] <methods_> what welder?
[16:20:14] <roycroft> plus, the biggest collets i have for my torch are 1/8"
[16:20:30] <roycroft> and i think that if i had a more powerful welder i'd need to use bigger electrodes
[16:20:54] <roycroft> so 250a with 1/8" electrodes sounds ok?
[16:21:12] <roycroft> i was going to do this job in stick mode
[16:21:13] <methods_> yea id' give it a try for sure
[16:21:26] <roycroft> but i don't want to spend half my life grinding to make things look pretty
[16:21:36] <roycroft> so i thought that tig would be better in that respect
[16:21:44] <roycroft> and i don't mind that it will take a lot longer to do
[16:22:42] * roycroft will give it a go at full power, and not mess with pulsing
[16:23:46] <roycroft> and i'll definitely be cleaning up the metal before i weld it - i'll be welding a bunch of hot roll
[16:24:52] <methods_> yeah definitely with tig you want to make sure you do a good weld prep
[16:24:54] <roycroft> ac at about 75% en would probably clean up the slag, but i want to keep this simple
[16:25:53] <roycroft> and i don't want to be regriding my electrode every two minutes

[18:29:17] <pink_vampire> how do i setup the kinematics in linuxcnc?
[18:29:23] -!- SaldoT has quit [Quit: Leaving]
[18:29:40] <pink_vampire> it is done in hal?
[18:29:45] <andypugh> Yes.
[18:29:54] <Tom_L> in the axis / joint sections
[18:29:55] <andypugh> Which kinemtaics?
[18:30:11] <pink_vampire> i want to make inverted bipod
[18:30:48] <andypugh> Anyway, if you look in the HAL file you will see that there is (typically) a “loadrt trivkins”
[18:30:53] <pink_vampire> http://wiki.linuxcnc.org same as this one
[18:31:13] <andypugh> You would just “loadrt bipodkins"
[18:31:32] <andypugh> (But you would need to find that kins file, it’s not part of the standard set
[18:32:05] <pink_vampire> where do i find it?
[18:33:12] <andypugh> https://github.com
[18:33:33] <andypugh> (you would need to compile it, I suspect)
[18:34:03] <pink_vampire> how do you compile it?
[18:35:43] <andypugh> There is a page here describing how to write a kins, and the example is a bipod.
[18:35:44] <andypugh> http://linuxcnc.org
[18:37:27] <pink_vampire> lets see
[18:38:00] <andypugh> You can compile that bipodkins using halcompile.
[18:38:05] <andypugh> (I just did it)
[18:38:21] <andypugh> http://linuxcnc.org
[18:38:53] <andypugh> But really just save the bipokins.c file somewhere then “sudo halcompile —install bipodkins.c"
[18:39:51] <Tom_L> JT-Shop, what's the command to start the QT Designer?
[18:40:19] <JT-Shop> to edit a vcp its oddly editvcp
[18:40:33] <Tom_L> i'm looking at your tutorial
[18:40:49] <Tom_L> "Start QT Designer....."
[18:40:55] <Tom_L> i'm a noob remember?
[18:40:59] <pink_vampire> no9w, this is my main cnc machine computer (normal xyzc), i just want to add this bipod machine and have 2 icons on the desktop, icon for each machine
[18:41:01] <JT-Shop> it should be in there...
[18:41:11] <JT-Shop> which tutorial and what page?
[18:41:22] <andypugh> pink_vampire: bipodkins creates a HAL parameter “Bx” which (somehow) defines the geometry.
[18:41:31] -!- Tom_dev has joined #linuxcnc
[18:42:06] <pink_vampire> so i need a dedicated computer?
[18:42:24] <Tom_L> gnipsel.com/pyqt5/app1.html
[18:42:53] <andypugh> pink_vampire: Eh? What thing that I said made you decide that?
[18:43:18] <andypugh> You can have several configs on the same PC.
[18:44:15] <andypugh> You can either plug in a different machine or (depending on the hardware) simply have 6 steppers hooked up at all times and have different configs use different ones.
[18:44:28] <pink_vampire> i just don't want to do damage to my regular cnc configuration, so i'm extra careful

[18:44:41] <JT-Shop> oh that's not qtpyvcp
[18:44:51] <Tom_L> well crap
[18:45:05] <andypugh> pink_vampire: Every folder in the linuxcnc/configs folder is a separate config.
[18:45:23] <Tom_L> JT-Shop, somebody said yesterday you had a page showing all the rules for qtpyvcp
[18:45:39] <andypugh> Though you can also have multiple configs (ie INI files) in the same folder if you want them to share files. You probably don’t want that.
[18:45:48] <JT-Shop> yes for all the status items yea
[18:45:50] <pink_vampire> i duplicate the my-mill folder, and replace all the stuff in the ini file from my-mill to bipod-cnc
[18:46:06] <JT-Shop> https://qtpyvcp.kcjengr.com
[18:46:13] <andypugh> pink_vampire: Just start a complete new config with stepconf, I reckon.
[18:46:16] <JT-Shop> https://qtpyvcp.kcjengr.com
[18:46:16] <Tom_L> how is ^^ that different than the qtpyvcp editor?
[18:46:29] <pink_vampire> i saved the bipodkins.c in /linuxcnc/bipod-cnc
[18:46:51] <andypugh> Did you try compiling it?
[18:47:02] <andypugh> should take seconds
[18:47:39] <Tom_L> JT-Shop, they both look quite similar
[18:48:32] <pink_vampire> i'm working on that
[18:48:50] <JT-Shop> Tom_L: meet you down in the beer cave
[18:48:56] <Tom_L> k
[18:50:08] <pink_vampire> i got some text in the terminal
[18:50:59] <jthornton> Tom_L: when you run editvcp it does a lot of things under the hood while the qt designer looks the same until you scroll down and see all the qtpyvcp widgets

[19:55:51] <andypugh> pink_vampire: I am afraid that I don’t know anything about bipodkins. Does it always ferror when you switch to World mode?
[19:56:16] <pink_vampire> correct
[19:56:31] <andypugh> It may be that the INI Home position is actually somewhere that the kins can’t reach.
[19:56:56] <pink_vampire> mmm
[19:57:00] <pink_vampire> lets see
[19:57:04] <andypugh> Just a guess.
[19:57:06] -!- togo has quit [Ping timeout: 258 seconds]
[19:57:09] <andypugh> I really have no clue.
[19:57:19] <pink_vampire> sound like a good guess
[19:57:55] <pink_vampire> me neither
[19:58:44] <andypugh> The maths is fairly simple, try running the calculations by hand to see if the home position etc makes sense.
[19:58:48] <pink_vampire> maybe to remove the C axis?
[19:59:52] <pink_vampire> i don't even build the machine yet, I don't want to order stuff before I know I have a controller
[19:59:53] <andypugh> Basically when you go to workd mode it swaps from using forward kins to calculate world position from joint position to using inverse kins to calculate joint posiitons from world position. And the teo calcs need to give the same results.
[20:00:10] <andypugh> Which joint is f-erroring?
[20:00:15] <pink_vampire> 1
[20:00:43] <andypugh> I would suggest running 2.8 for any complex kins machine.
[20:01:14] <andypugh> But clearly folk had bipods running on emc2 v2.3 and maybe earlier.
[20:01:59] <pink_vampire> it will make it much more complex, i will need a new computer
[20:03:25] <pink_vampire> I tried now to load this configuration from the linux cnc menu sim.axis.vismach.hexapod-sim
[20:03:25] <andypugh> I suggest it is time to become the IRC Bipod expert, then you can tell me how they work :-)
[20:03:33] <pink_vampire> and it is work perfect
[20:03:48] <pink_vampire> LOL
[20:03:50] <pink_vampire> maybe

[21:43:40] <Tom_L> hazzy-m around?
[21:43:50] <hazzy-m> yea
[21:44:09] <Tom_L> i realized i don't have all the widgets
[21:44:17] <Tom_L> where do i get the linuxcnc widgets?
[21:44:19] -!- Nick001-Shop has quit [Ping timeout: 244 seconds]
[21:44:27] <Tom_L> i did get some from the master branch
[21:45:33] <hazzy-m> if they don't show up in the "widget box" on the left side of designer that usualy means you didn't use editvcp to start designer, or you are missing the libpyqt5.so files
[21:45:43] -!- gloops has quit [Ping timeout: 268 seconds]
[21:46:01] <Tom_L> i did editvcp to start but i'm still missing some
[21:46:10] <Tom_L> i do have some of the "QT" widgets
[21:46:24] <Tom_L> over the standard ones
[21:47:12] <hazzy-m> https://qtpyvcp.kcjengr.com
[21:47:35] -!- Tom_dev has joined #linuxcnc
[21:47:40] <hazzy-m> did you clone and install, or just install with pip and git+ a url
[21:47:54] <Tom_L> clone
[21:48:00] <Tom_L> i think :)
[21:48:11] <Tom_L> i also installed master
[21:48:28] <Tom_L> because master had some of the widgets
[21:49:38] <hazzy-m> ok, so you have a qtpyvcp folder somewhere in your home dir?
[21:49:45] <Tom_L> yes
[21:50:14] <Tom_dev> i also have a qtpyvcpmaster folder
[21:50:20] <hazzy-m> great!
[21:50:34] <Tom_dev> but i ran the install.sh and still missing some of the widgets
[21:50:55] <hazzy-m> hmm, do you get any warnings or erros?
[21:51:02] <Tom_dev> the more 'linuxcnc' specific ones
[21:51:09] -!- rmu has quit [Ping timeout: 255 seconds]
[21:51:11] <Tom_dev> like tool table etc
[21:51:33] <Tom_dev> i lost the page i was on that showed them...
[21:52:07] <Tom_dev> https://forum.linuxcnc.org
[21:52:12] <Tom_dev> that got some of them
[21:53:00] -!- rmu has joined #linuxcnc
[21:53:19] <Tom_dev> that copied libpyqt5_py2.so and libpyqt5_py3.so
[21:54:12] <hazzy-m> do you get eny widget sections in with QtPyVCP in the section header name?
[21:55:26] <Tom_L> wait.. maybe i do have them
[21:55:45] <Tom_L> the menu just looks different than his example
[21:56:11] <Tom_L> he had a linuxcnc pulldown with widgets and that's what i was looking for
[21:57:49] <hazzy-m> it should look something like this: https://i.imgur.com
