[00:00:50] <Tom_L> your 1.4 factor is pretty close on the DC volts
[00:02:10] <Tom_L> https://www.rapidtables.com
[00:02:54] <RyanS> i'm not fussed if the control cabinet is a boat anchor, I just don't want a cheapo SMPS as it's just one more thing to trouble shoot
[00:03:49] <Wolf__> makes power ir makes smoke
[00:03:53] <Wolf__> ir/ot
[00:03:59] <Wolf__> … OR
[00:04:11] -!- Ross has quit [Ping timeout: 265 seconds]
[00:04:38] -!- nallar has joined #linuxcnc
[00:04:38] nallar is now known as Ross
[00:05:04] <RyanS> a chuck of copper wire is caveman simple that I can't see it ever failing
[00:05:42] * Wolf__ could manage to break it somehow
[00:06:12] -!- asdfasd has joined #linuxcnc
[00:06:47] <Wolf__> I dont let the magic smoke out of things, I usually end up with components turing in to smoke
[00:07:46] <renesis> cool splosions are little chunks blowing out of packages
[00:08:02] <Wolf__> Kinda like this n-fet motor controller thats missing a mosfet https://i.imgur.com
[00:08:21] <renesis> like, little cube of plastic missing from middle of to-220 package with a crack across entire package
[00:08:42] <renesis> wolf__: very impress
[00:08:53] <RyanS> ( I'm imagining the ape-men in 2001 discovering the transformer psu next to the monolith)
[00:09:25] <renesis> some random PCB with blown out protection sections is the monolith
[00:10:10] <Wolf__> that one sucked, was a 15A roboclaw motor controller, blew out the fet driver ic and cooked one of the MCU pwm channels
[00:10:35] <Wolf__> well 3 out of 4 fet drivers blew out…
[00:10:37] <renesis> what do you think started the mess?
[00:11:46] <Wolf__> hooking a high current wheelchair motor to it and having it go from running free wheel to dropping on to carpet
[00:12:40] <RyanS> I have two wheelchair motors waiting for a use
[00:13:10] <Wolf__> https://i.imgur.com I need a drive gear
[00:13:17] <Wolf__> and motor controllers
[00:13:30] <Wolf__> I have 4 sets to play with
[00:15:31] <Wolf__> and I need a hill mower
[00:16:49] <RyanS> the Neanderthals who design wheelchairs don't seem to be aware of LiPo batteries, so SLA it is
[00:17:05] <Wolf__> same here
[00:17:24] <Wolf__> usually 70ah/24v worth
[00:17:48] <Wolf__> er
[00:18:03] <Wolf__> 35ah/12v, that doesnt add up that way i think
[00:20:46] -!- mozmck_lp has quit [Quit: Leaving.]
[00:22:01] <RyanS> so heavy and then every few years there's some 'newly invented' stair climbing wheelchair which bombs out commercially because the price is prohibitive. there's no innovation
[00:23:34] -!- ziper has quit [Quit: Leaving]
[00:25:34] * Wolf__ has china level innovation planned http://www.evatech.net
[00:27:03] <Wolf__> plus they are usually paid for by medical insurance so the companies making them dont care, nor do most people using them
[00:27:30] <RyanS> China innovates far more than any wheelchair manufacturer
[00:27:57] <Wolf__> on the positive side, I can usually find full mobility chairs for ~$300
[00:29:43] <RyanS> yeah or government funding. same thing with hospitals, even the most simple consumables is absurdly priced
[00:30:00] <Wolf__> yup
[00:31:02] <Wolf__> I am planning on making the track system semi modular so I’m not trapped with it being always a lawnmower
[00:31:22] <RyanS> I'll sell you my old one for $20,000, 1/2 the price of the new one :-)
[00:31:44] <Wolf__> lol
[00:31:48] <XXCoder> health assistance? price dot to right 2 times for price, innovation move dot to left million times
[00:32:38] <Wolf__> yup, why innovate when you can make more profit off crap that is old tech
[00:34:14] <RyanS> I want to turn it into a platform to shift steel sheets to the shed and use the actuators from the seat to jack them onto the plasma table
[00:34:32] <Wolf__> hehe
[00:34:38] <Wolf__> I have a thing to do that
[00:34:42] <Wolf__> forklift
[00:35:11] <RyanS> but meh, will always forget to charge it
[00:36:17] <Wolf__> put small gas motor and alternator on it
[00:36:30] <XXCoder> invent true wireless power
[00:36:39] <Wolf__> kinda like the evatech stuff
[00:36:58] <Wolf__> or 1000w laser and solar panel
[00:38:36] <RyanS> there's this thing it's a 24V,mini fan heater, with I guess a microcontroller, they want $2000AUD for it
[00:39:08] <Wolf__> eh
[00:39:17] <RyanS> I use a truck light bulb lol
[00:39:40] <Wolf__> lol
[00:40:39] <RyanS> http://www.mo-vis.com
[00:40:59] <Wolf__> ugh, i forgot that I need to fix the alternator in my skid loader
[00:41:30] <Wolf__> lol
[00:41:49] <Wolf__> dome security camera heater
[00:42:50] <RyanS> https://www.ebay.co.uk im certain it's just an enclosure heater
[00:43:42] <XXCoder> great for abs 3d printer I guess
[00:44:53] <RyanS> yeah that is an example on their website but unfortunately they have no Australian distributor
[00:45:50] <Wolf__> https://i.imgur.com
[00:46:23] <Wolf__> with 40mm fan
[00:47:08] <RyanS> is it off the shelf?
[00:47:36] <Wolf__> possibly, its out of one of the big roadway camera domes
[00:48:22] <Wolf__> https://i.imgur.com
[00:48:54] <RyanS> probably mains voltage
[00:50:25] <Wolf__> 24v may be AC tho
[00:51:40] <Wolf__> I know one way to find out, plug it in to my desktop psu lol
[00:53:12] <RyanS> I could attach this to a cpu heatsink and have a fan blow through it https://au.rs-online.com
[00:55:35] <Wolf__> https://i.imgur.com lol
[00:57:58] <RyanS> is that with the gueard removed?
[00:58:13] <Wolf__> no, it had two heaters
[00:58:27] <Wolf__> the metal box one is a coil element
[00:59:14] <RyanS> I guess just pass the air straight over the element
[01:00:30] <Wolf__> welcome to these if you want them
[01:01:00] <Wolf__> alum one the fan is dead, pulling 1.4A @14v
[01:01:09] <Wolf__> on the heating coil
[01:01:26] <RyanS> 10W.. is the air too hot if your hand is about 5cm away?
[01:01:41] <XXCoder> could use pid with it I guess?
[01:02:46] <Wolf__> idk, that little pos I burnt my hand on because I didn’t notice it on the camera gimbal
[01:03:14] <Wolf__> bigger coil gets nice and red at 2.2A/24v dc, with no fan running

[01:03:41] <Wolf__> just blowing in to it the glow went away tho
[01:05:12] -!- c-log has joined #linuxcnc
[01:06:08] <RyanS> I think the elements I linked is PTC and doesn't need a thermostat
[01:13:06] <Wolf__> this 10w thing I dont feel heat out of w/ the fan, but the fan is 5v so I cant push it
[01:14:35] -!- c-log has quit [Ping timeout: 240 seconds]
[01:15:50] -!- c-log has joined #linuxcnc
[01:17:22] <Wolf__> 10w chip heater was hitting 110C but thats with no fan...
[01:18:05] <RyanS> https://au.rs-online.com
[01:20:19] <Wolf__> if you want these two things let me know and I’ll toss them in the post for you
[01:27:26] -!- ve7it has quit [Remote host closed the connection]
[01:32:00] <RyanS> cool thanks, although i'm in Australia
[01:32:24] <Wolf__> just means its going to take a few to get there lol
[01:35:13] <RyanS> if it's not too pricey to send it, wouldn't want you to pay for it if they don't work for the application
[01:35:40] <Wolf__> i’ll look up the postage
[01:36:08] <RyanS> cool thanks for that
[01:37:31] <RyanS> 3059 Victoria is my postcode and state
[01:42:55] -!- swarfer has joined #linuxcnc
[01:43:26] <Wolf__> seems to be $14
[01:44:13] <Wolf__> from almost no weight up to 8oz (0.22kg)
[01:45:03] <RyanS> are they lightweight?
[01:45:34] <Wolf__> 0.07kg
[01:46:01] <Wolf__> the box I have weighs more lol
[01:46:45] <RyanS> just let me know if you want me to fix you up for the postage, PayPal etc
[01:47:31] <Wolf__> get your plasma cnc done so I have someone to copy =P
[01:48:35] <Wolf__> crap, I forgot to text the sword shop guy today to ask about the machine torch =/
[01:49:57] <RyanS> im stuck with analysis paralysis need to just dive into cad and revise it
[01:50:19] <Wolf__> I need to check my machine out
[01:50:27] <Wolf__> right now its inop
[01:50:52] <Wolf__> but I’m thinking someone dropped something on the torch lead
[01:51:56] -!- djinni` has quit [Quit: Leaving]
[01:54:04] <RyanS> the torches on the 300A machines have copper braided shielding sleeve, I guess that sort of current has massive EMI
[01:54:28] <Wolf__> well, yeah
[01:54:45] -!- swarfer has quit [Quit: swarfer]
[01:55:05] -!- ferdna has quit [Quit: Leaving]
[01:55:21] <Wolf__> 300A is a big plasma IMO
[02:01:23] <RyanS> hell have mercy on their power bill
[02:01:54] <Wolf__> at 300A of plasma, thats all billable usage lol
[02:02:12] <Wolf__> not home gamer hobby shop
[02:02:48] <Wolf__> I’ve hacked up 1.75”(44mm) with my 60A
[02:03:34] -!- djinni` has joined #linuxcnc
[02:08:25] <RyanS> yeah I think we did 12mm but lots of 2mm

[02:17:47] <Wolf__> I wonder if machine size was due to duty cycle
[02:19:47] <RyanS> i think oxy fuel is still more economical for over 50 mm
[02:21:30] <Wolf__> yup
[02:21:39] -!- gloops has joined #linuxcnc
[02:21:41] -!- IchGucksLive has joined #linuxcnc
[02:21:48] <IchGucksLive> morning from germany
[02:22:01] <IchGucksLive> Bullrun Pamplona first day
[02:22:01] <Wolf__> most of my work is 5mm and 12.7mm so plasma is quicker and easier imo
[02:27:23] <RyanS> how come closed loop is good in EMI? something to do with the control algorithm?
[02:28:28] <Wolf__> depends, talking closed loop all in one like clear path or closed loop like analog servo setup
[02:29:17] <RyanS> stepper hybrid
[02:29:49] <Wolf__> clearpath type setup is going to have a leg up with EMI due to control signal is dumped direct at the motor/controller combo
[02:30:37] <Wolf__> least imo
[02:33:23] <Wolf__> stepper hybrid I dont know about, thats a step/dir controller w/ added feedback to Lcnc? or something self closed loop smart?
[02:39:56] <Wolf__> when i hear closed loop stepper now I think http://a.co type thing
[02:39:56] <IchGucksLive> RyanS, morning
[02:40:24] <IchGucksLive> RyanS, did you see my new plasma CNC at 680 Euro Build
[02:40:59] <gloops> the hybrid is basically a stepper with encoder
[02:41:19] <Wolf__> I know what it is =)
[02:41:39] <gloops> well the encoder info can be used the same as an encoder
[02:41:47] <gloops> any encoder
[02:42:02] <Wolf__> but having a driver box with meters of wire I dont see how that helps combat EMI
[02:42:05] <RyanS> I think the closing the loop between stepper and driver means the current is regulated and also the torque can respond to the load
[02:42:37] <Wolf__> that part is true
[02:42:42] <IchGucksLive> RyanS, this featuers is also on the Low cost DM556d
[02:42:52] <RyanS> IchGucksLive don't think so
[02:42:58] <Wolf__> because the controller has the feedback from the loop
[02:43:34] <RyanS> i haven't seen your design
[02:43:43] <IchGucksLive> RyanS, https://www.youtube.com
[02:45:00] <gloops> why would there be any need for extra metres of wire? the driver is enroute to the motor just the same
[02:45:11] <gloops> there might be a small amount of wire more
[02:45:27] <IchGucksLive> gloops, i got up to 10meters at the large plasma
[02:45:30] <Wolf__> on a plasma table gantry
[02:46:01] <IchGucksLive> gloops, 72V is hard to pusth at this length Double it in wire
[02:46:13] <gloops> you still have to get power to the servos?
[02:46:16] <IchGucksLive> gloops, brazil is out
[02:46:27] <gloops> yes Belgium did well
[02:46:30] <Wolf__> driver > motor/encoder, vs controller > one of them all in one is a advantage
[02:46:58] <RyanS> IchGucksLive is that an ohmic sensor?
[02:47:16] <IchGucksLive> sensor ?
[02:47:26] <gloops> i dont think it would any difference that would effect the design, regarding emi
[02:47:34] <IchGucksLive> its the GND at Torch Start above part
[02:47:50] <IchGucksLive> gloops, there is
[02:48:03] <RyanS> to detect the plate
[02:48:14] <IchGucksLive> gloops, it is a Huge Diggerence if you use M542 or DM556
[02:48:51] <IchGucksLive> RyanS, it can fire the torque at free air and then go down
[02:48:53] <gloops> i think Wolf is saying that using a driver/stepper is an emi liability compared to servo
[02:49:01] <IchGucksLive> SELF ignite
[02:49:11] <IchGucksLive> RyanS, at 220V
[02:49:28] <IchGucksLive> RyanS, the plasma is a s-cut 50
[02:49:31] <Wolf__> well, more wires = more antennas
[02:49:42] <IchGucksLive> Wolf__, you got it
[02:50:05] <IchGucksLive> if you fire up in wrong conditions the PC goes off
[02:50:19] <Wolf__> if you can run shielded twisted pair direct to the motor/driver combo = optimum imo
[02:50:39] <gloops> that would be a problem if driver wiring could not be done to prevent emi - but it can, and is
[02:50:42] <Wolf__> power raw to the thing as well, get filtered by the unit
[02:50:50] <IchGucksLive> there is double shiled chain cable
[02:51:21] <Wolf__> I like the idea from a simplicity standpoint
[02:51:22] <IchGucksLive> Wolf__, but you need to ground at all sides
[02:52:10] <Wolf__> I’m starting to see why https://www.youtube.com type units make sense from a control system layout
[02:52:13] <IchGucksLive> my last big plasma got 8double ground clamps
[02:52:27] <RyanS> IchGucksLive yeah but do you use a floating head to zero the torch against the plate?
[02:52:49] <IchGucksLive> the big ones got 2 Z setups
[02:53:05] <IchGucksLive> with a switch
[02:53:19] <IchGucksLive> so you G38 down till it triggers
[02:53:41] <IchGucksLive> Benefit is as the THC fails it also can move 10mm
[02:54:11] <IchGucksLive> You can act then as you hear it touching at cut speed
[02:56:13] <IchGucksLive> RyanS, querry
[02:58:46] <gloops> Wolf configuring servos isnt simple though
[02:59:16] <Wolf__> i’m talking clearpath sorta unit
[02:59:32] <Wolf__> not full blown analog servo
[02:59:55] <Wolf__> where you are messing with the halls timing + encoder
[03:00:00] <Wolf__> and pids
[03:00:05] <Wolf__> with no autotune
[03:01:11] -!- Deejay has joined #linuxcnc
[03:01:46] <gloops> Lcvette has been trying for 3 months and hasnt made a chip yet lol
[03:01:46] <Deejay> moin
[03:03:37] <Wolf__> is it a common servo driver or some old low documented surplus stuff?
[03:04:11] <gloops> not sure what type, he is having major problems
[03:06:33] <Wolf__> all of my servo drivers are AMC B25A20 which are very common and are OEM for a few big names, picked due to fitting specs + we use to have 3-4 people in here running them
[03:33:47] <IchGucksLive> im off 2 garden

[04:12:07] <gloops> ive got some brake pads to fit
[04:14:17] <gloops> hmm, an hours job ordinarly, but this is a french van
[04:15:15] <XXCoder> so just threaten it and it breaks apart?
[04:15:28] <gloops> if only...
[04:15:44] <XXCoder> reality is that french is tough people lol
[04:16:18] <gloops> being french it will be an infuriating design, numerous sockets or special torx fittings stuff like that, at least 2 totally inaccesible nuts
[04:16:39] <gloops> need to remove many unrelated components to access the one you want
[04:16:41] <XXCoder> lol
[04:19:22] <gloops> ford escort you needed 3 or 4 spanners to do just about anything, 10mm, 13mm, 17mm, 21mm
[04:19:53] <XXCoder> I still remember my quest van
[04:20:03] <XXCoder> need one part replaced? remove air manfold
[04:20:17] <XXCoder> which of course needs 3 other parts to be removed
[04:20:33] <XXCoder> thankfully chain stops there
[04:22:03] <gloops> nightmare
[04:22:35] <XXCoder> you come in and see guy with piles of scattered car parts
[04:22:42] <XXCoder> "oh just needed to replace this $5 part"
[04:22:58] <gloops> the engines and suspension and so on are assembled out of the car these days, and pushed up from underneath, if you cant get the car in the air its difficult to work on
[04:23:44] <gloops> yeah i had a look at doing the clutch on a citroen, the speeded up youtube vid was still about 30 minutes long lol
[04:23:57] <gloops> just remove - everything

[14:57:35] <amxen> hello
[14:57:46] <gloops> evening
[14:58:20] <gloops> what is going to be risen skunkworks?
[14:58:38] <skunkworks> http://electronicsam.com
[14:58:48] <skunkworks> I have a small cnc that needs some tlc
[14:58:56] <amxen> iv come here after watching a youtube video about my break out board . can some one help
[14:59:40] <amxen> its one othe the blue 5 Axis Cnc Breakout Board of ebay
[14:59:59] <amxen> i dont have any output from the board
[15:00:25] <skunkworks> amxen: link?
[15:00:44] <amxen> i have input on the pp port of 3.7v dc on each pin but no out put to the drivers
[15:01:44] <pcw_home> are you suppling 5V to the breakout?
[15:02:07] <amxen> its one of these
[15:02:09] <amxen> https://www.ebay.co.uk
[15:03:06] <gloops> those are a doddle amxen
[15:03:06] <amxen> im giving it 5v input on the green block
[15:03:16] <gloops> plug usb in
[15:03:18] <amxen> not using usb
[15:03:39] <amxen> will it only work if i use usb 5v
[15:04:08] <gloops> have you tried the usb supply?
[15:04:33] <amxen> no i dont have a usb to usb cable handy
[15:04:50] <pcw_home> I think I heard that there are missing power connections on one flavor of those cards (not sure if it was the green or blue one)
[15:05:17] <pcw_home> The inputs need 12/24V to work
[15:05:25] <pcw_home> 12 24V power
[15:05:30] <gloops> hmm, i think the 5v in pin might need a jumper
[15:05:48] <gloops> has a light come on the board?
[15:06:15] <amxen> its the green one i have . i have a red light on it when i power it up . from the long green block ( same side as the outputs 0
[15:06:47] <gloops> https://hallroad.org
[15:07:43] <gloops> im not sure if putting the power in that 5v in, will only power the output side, you need to get power to the parport side as well, might be the position of the jumper
[15:08:31] <amxen> from what i understand you can power it with 5v usb or 5v on the other side in the green block. iv used the green block as i dont have usb cable
[15:08:49] <gloops> Ichsguckslive uses these boards every day for building machines but i think youve missed him for today
[15:08:49] <amxen> on the pc5v
[15:09:13] <amxen> aaarrg
[15:11:02] <amxen> maybe i should try another board or the USB side. any recommendations for a board
[15:11:47] <gloops> those boards are fine
[15:12:55] <gloops> i use one for my router, but i use usb for supply, as i say you may need to change the jumpers to power from the other side
[15:13:57] <gloops> also, it may not be power supply issue, are you sure the parport is working?
[15:16:28] <amxen> iv tested iv got power coming in . im getting 3.7v dc on ports 2345678
[15:16:37] <gloops> ok
[15:17:03] <gloops> so you need to make sure the signals are reaching the board, from the parallel port
[15:17:27] <gloops> using linuxcnc? or mach3?
[15:17:36] -!- ferdna has quit [Quit: Leaving]
[15:17:44] <amxen> i get 3.7 left the 0 right then 3.7v up and 0 down etc
[15:17:54] <amxen> mach3
[15:18:22] <gloops> right, you installed the mach3 drivers?
[15:19:21] <amxen> is there drivers for the board . i thought it just needed the input to be going to the board . but no iv not installed drivers for the board
[15:19:40] <CaptHindsight> LPT port driver
[15:19:48] <gloops> not for the board, mach3 has its own parallel port drivers
[15:19:50] <CaptHindsight> configs for the LPT break out board
[15:20:08] <gloops> this always happens with mach3 thats why i dont like it
[15:20:19] <amxen> the computer that im using was used on my other cnc machine that i have now sold
[15:20:30] <amxen> im using the same mach3
[15:20:41] <CaptHindsight> and it only runs on winders
[15:22:00] <amxen> so the computer and mach3 im using was being used to power another cnc . So it should all be the same
[15:22:29] <gloops> well, if you jog an axis, is the voltage fluctuating on the relevant step/dir pins on the board?
[15:22:33] <CaptHindsight> I though mach3 support was only here Sunday mornings along with beer church
[15:25:34] <amxen> if i jog i get 3.7v on the board input but nothing on the out up
[15:25:36] <amxen> out put
[15:26:14] <gloops> so the parport is working
[15:26:50] <skunkworks> kinda like watching paint dry
[15:26:52] <skunkworks> http://electronicsam.com
[15:27:02] <gloops> but the signal isnt crossing to the output side - board power issue, it needs 5v to bridge the isolation
[15:27:15] <gloops> get a usb to usb and it will work
[15:27:51] <gloops> all night walmart might have one
[15:28:04] <amxen> ok ill try the usb . its strange that everything iv looked at is saying it can be powered from the pc5v
[15:28:33] <gloops> have you seen any mention of the jumper amxen? in your research?
[15:29:17] <gloops> i know there is one, maybe 2, id get up and look but the garage is so far away lol
[15:29:20] <amxen> no i have seen a jumper but i think that is to unlock the 5th axis on pin 17
[15:29:34] <CaptHindsight> skunkworks: what is the small mill?
[15:29:40] -!- holzjunkie1 has joined #linuxcnc
[15:29:59] <pcw_home> Those breakouts do not have isolated outputs ( just buffered outputs )
[15:30:13] <holzjunkie1> Hy @all
[15:30:22] <CaptHindsight> skunkworks: is that the saddle?
[15:30:29] <pcw_home> the buffer chips require 5V
[15:30:40] <gloops> ok no i cant see a jumper on this board
[15:31:11] <gloops> you have grounded the 5v-?
[15:31:21] <pcw_home> YOu can check if the buffer chips have power by measuring pin 20 of the chip to ground
[15:33:23] <amxen> yes through the small 5v power supply
[15:33:28] <pcw_home> it may be that the terminal block only powers the step drive connections, not the buffers
[15:33:49] <skunkworks> CaptHindsight: http://electronicsam.com
[15:34:03] <amxen> i think the only thing to do is try usb side
[15:34:08] <skunkworks> CaptHindsight: no - some cast iron we had that I am going to use to make a 4 inch riser
[15:34:20] <skunkworks> from an old grinder
[15:34:52] <gloops> pcw_home yes you need 5v to both sides
[15:35:31] <pcw_home> Yeah, so that suggests the buffers are powered by the USB side
[15:35:43] <gloops> ordinarily the usb circuit does both, i think putting power to the 5v pin only serves the output array
[15:36:18] <pcw_home> weird...
[15:36:38] <gloops> on the older boards there are 2 5v in pins, one each side, you can use only 1 if you fit a jumper
[15:38:05] <gloops> what machine is it anyway amxen?
[15:38:46] <amxen> its a grizly g0704 mill
[15:39:22] <gloops> excellent
[15:40:21] <amxen> converted the screws and mounts . just need to power it now
[15:40:59] <holzjunkie1> is it possible to use an usb mach3 mpg on linuxcnc with all features???
[15:43:17] <gloops> amxen on my board when its powered up, i get a green light - where the 12-24v marking is near the outputs
[15:43:44] <amxen> all i get is a red light
[15:44:00] <Rab> holzjunkie1, is this helpful? http://wiki.linuxcnc.org
[15:44:14] <gloops> i think youll be ok with usb supply
[15:45:13] <holzjunkie1> great thx
[15:45:35] <Rab> Man, sure hope nobody's using a wireless pendant for e-stop.
[15:45:54] <Rab> (Or wired USB pendant for that matter)
[15:46:54] <SpeedEvil> Wireless pendant for e-stop would be fine, if it was of the deadmans handle sort.

[15:56:51] <fragalot> this heatwave
[16:00:29] <amxen> ;;ok just been down and tested the power supply to the bob . now im now electrician but it should not be -5.3 v should it
[16:02:47] <amxen> im sure it should be +5.3v dc not -5.3v dc
[16:06:25] -!- holzjunkie1 has quit [Ping timeout: 260 seconds]
[16:08:31] <gloops> one of the electricians here might explain
[16:11:54] <jesseg> amxen, I don't know what's been going on since I just popped in for a peek... but often when you read -5.3v instead of the expected +5.3, it's because you have the red and black leads on the volt meter swapped either at the meter or in your hands...
[16:13:48] <gloops> you might have the BOB wiring crossed + to -
[16:13:55] <amxen> no i check the ac Voltage and my cables are correct im a heating engines so do a lot of voltage testing. the leads never get taken out of my multmeter .
[16:14:46] <gloops> you use a phone charge for 5v supple
[16:14:48] <amxen> they are correct black on the ground and red on the live and im getting -5.3v dc
[16:15:11] <gloops> is this a power supply you know?
[16:17:00] <amxen> i bought it for this job off ebay

[16:17:56] <jesseg> well I suppose from china they may have labeled + and - wrong on a power supply LOL.. but probably not..
[16:18:12] <amxen> iv disconnected from the bob and im reading -5.3v dc
[16:18:22] <jesseg> amxen, so double check your volt meter right off the output of the supply.. And if that reads backwards, check your volt meter on a 9v battery.
[16:18:28] <amxen> on the supply
[16:18:33] <gloops> jesseg thats what im thinking yeah
[16:18:46] <jesseg> ok check a 9v or 1.5v battery make sure volt meter is all correct
[16:18:52] <jesseg> btw what is a bob in this case?
[16:19:01] <gloops> if the supply is wire wrong, youll be feeding the wrong pins on the bob

[16:19:54] <gloops> i used an old phone charger on a breakout board, was fine, aboyt 5.5v i dunno 1 amp or something
[16:21:18] <amxen> ok lols like your correct leads the wrong way. i think im trying to hard haha
[16:23:01] <gloops> strange things happen to the mind during the lonely days in the garage lol
[16:23:16] <amxen> yer telling me haha
[16:24:08] <amxen> has to be something on the bob . ill try the usb if thats not a fix ill try a new bob

[19:04:23] <hazzy-lab> Does Block Del default to enabled? Seems like it does, but I had not noticed this before

[20:00:58] <andypugh> hazzy-lab: I have never even used it, or checked.

[20:06:02] <hazzy-lab> andypugh: It is very useful, for example it you have two parts that are very similar, except one does not have a hole pattern, you just put a "/" before the lines for the holes and use block del to choose whether to skip those or not

[20:10:36] <Tom_L> hazzy-dev is that described in the g or mcode doc anywhere?
[20:11:24] <Tom_L> i've heard of it but never used it with linuxcnc
[20:12:01] <Tom_L> found it..
[20:12:21] <andypugh> http://linuxcnc.org
[20:12:38] <Tom_L> yeah, looking at that page
[20:13:36] <Tom_L> it _would_ be helpful if it said it's default state
[20:17:47] <andypugh> I thought there was an M-coe for it, but it actually seems to be GUI-related
[20:18:04] <andypugh> Or so the docs say
[20:18:37] <andypugh> So, if it it on by default in Hazzy then you might want to take it up with the developer :-)
[20:22:20] <Tom_L> generally it's a toggle switch on the control
[20:22:39] <Tom_L> but i don't know the default state
[20:30:27] <pfred1> I had an out of body autoerotic tool pr0n experience today

[20:47:05] <Tom_L> how'd that work out?
[20:47:19] <hazzy-lab> andypugh: Yes, it is on by default in Hazzy, and it's developer can't figure out why :D
[20:47:46] <Tom_L> what about axis?
[20:47:53] <Tom_L> did you try it there?
[20:48:39] <hazzy-lab> Nah, been being too lazzy
[20:49:23] <hazzy-lab> Aha! It is on by default in axis too!
[20:49:42] <Tom_L> meaning it ignores code after /
[20:49:55] <hazzy-lab> Right
[20:50:17] <hazzy-lab> But opt stop also seems to be on by default in hazzy, but not in axis, odd
[20:50:34] <Tom_L> that i have used
[20:52:10] <skunkworks> it is 'squared..'
[20:52:11] <skunkworks> http://electronicsam.com
[20:52:39] <Tom_L> do you _ever_ play with small junk?
[20:52:53] <hazzy-lab> Nice sam!
[20:53:15] <hazzy-lab> What type of band saw is that? Does it have a rolling table?
[20:56:44] <hazzy-lab> Interesting, axis seems to restore the previous opt stop state on startup
[20:57:40] <Tom_L> huh
[20:57:53] <Tom_L> is it stored in the .var file?
[20:58:50] <hazzy-lab> In .axis_preferences
[20:58:59] <hazzy-lab> block del is also stored
[20:59:14] <Tom_L> huh
[20:59:39] <hazzy-lab> So I guess both block del and opt stop default enabled, but most of the time axis overrides that with
[21:00:10] <hazzy-lab> Seems kinda funky to have those enabled by default

[21:24:19] <hazzy-lab> oh ho! Very nice `Wolf
[21:24:55] <hazzy-lab> That is mighty cute!
[21:25:24] <`Wolf> labored long hours of clicking order here, thats a saunders machine works pallet
[21:26:05] <hazzy-lab> Yes, unmistakable as a SMW!
[21:26:09] <hazzy-lab> What size?
[21:26:18] <`Wolf> 8”x6”
[21:26:27] <hazzy-lab> That's what I though
[21:26:51] <hazzy-lab> That will be very handy
[21:27:17] <`Wolf> when it showed up and I looked at it I instantly felt better about just ordering it vs trying to diy one on the manual machine lol

[21:30:08] <`Wolf> now to figure out why my vise is 0.009” out
[21:34:32] <skunkworks> hazzy-lab: yes - jet with a air assist table. works ok
[21:37:00] <`Wolf> 0.0025” of play 3” from the center of the x axis, I think my gib needs adjusted lol
[21:37:42] -!- andypugh has quit [Quit: andypugh]
[21:48:18] <`Wolf> wow, I knew I forgot something after I got this machine here, never fully checked the x gib… already moved it over 1/2” and its still not tight yet. Not sure how the hell this thing was cutting w/ any tolerances
[21:52:54] <CaptHindsight> https://imgur.com
[21:57:40] <`Wolf> nice
[21:59:18] <`Wolf> I noticed before that one of the gib screws was a pan head with a washer, now I see why it was off, stock screw missing you can’t set the gib where it needs to be, smaller standard head of a m6 SHCS jams behind the gib and locks the table up
[22:11:34] <`Wolf> https://i.imgur.com
[22:11:43] <`Wolf> I don’t think thats correct

[22:24:50] <`Wolf> wiggle wiggle,… 0.0003 +/- swing (0.0006” tir) on my X at the middle of travel, I think this thing must have spent its whole life in the same 7” section of the table travel
[22:26:53] <JT-Mobile> most production machines will wear out one spot
[22:28:02] <`Wolf> this was a home shop doing prototypes, but I guess the vise lived in one spot most of the time
[22:28:50] <`Wolf> not sure how it wore down with almost 3 thou of play in it
[22:29:36] <`Wolf> https://i.imgur.com
[22:29:45] <`Wolf> and thats wasn’t at the end of the table
[22:30:14] <JT-Mobile> what kind of mill is it?
[22:30:39] <`Wolf> Jet 840
[22:32:50] <JT-Mobile> I'm guessing the ways are not hardened? dunno
[22:34:22] <`Wolf> not sure, gib might have odd wear on it from being loose
[22:38:11] <`Wolf> maybe reason to learn how to hand scrape lol
[22:40:09] <JT-Mobile> first figure out what is worn the gib or the ways, if the gib is a soft metal I'd suspect it first
[22:40:51] <`Wolf> it was stupid loose also, moved it in about 1/2”
[22:41:36] <JT-Mobile> well that could be true too, check the play at the ends to see if they are overly tight now
[22:43:12] <`Wolf> whats the amount of TIR at the ends of a 30” table supposed to be around?
[22:44:34] <JT-Mobile> I guess it depends on the machine, your measuring the spindle TIR?
[22:45:32] * JT-Mobile has a long day touring NASA and is time to sleep...
[22:45:52] <`Wolf> just the table right now
[22:46:38] <`Wolf> was tramming in the vise and noticed that I was jumping 2thou when I bumped the x handwheel
[22:46:50] <JT-Mobile> ah
[22:47:12] <`Wolf> by jump,I mean the table moved 2thou and didn’t move back lol
[22:47:31] <JT-Mobile> yea something loose/worn... goodnight

[23:14:50] <hazzy-lab> `Wolf: Is there an extra zero in the "wiggle wiggle" values? I would pretty happy with .0003" on an old machine
[23:15:13] <XXCoder> jetpower!
[23:15:42] <`Wolf> did you look where I had the indicator?
[23:16:16] <`Wolf> its around 0.0003” if I tug on the X hand wheels lightly
[23:17:36] <hazzy-lab> That does not seem bad, (with the indicator mounted to the head) If the indicator were mounted to the knee then I would be concerned
[23:17:54] <`Wolf> knee was locked
[23:18:01] <`Wolf> and the Y
[23:18:24] <`Wolf> with the X locked the tir on the Y unlocked is 0
[23:19:27] <`Wolf> knee gib you can watch the whole thing tilt when you undo the lock lol
[23:19:48] <hazzy-lab> A locked knee can still contribute to a lot of play (at least it does on my clapped out BP :D)
[23:20:11] <XXCoder> have there been any good replacements to bp company?
[23:20:40] <hazzy-lab> XXCoder: Replacement parts?
[23:20:57] <hazzy-lab> BPs are still made, they are now owned by Hardinge
[23:21:27] <XXCoder> nah company that makes in least to similiar level of quality and such machines
[23:21:39] <`Wolf> knee is tight, like I said, same test point with the X gib locked, Y gib unlocked 0 movement on the 0.0001” dial
[23:22:18] <hazzy-lab> The new Hardinge BPs are VERY nice machine, IMO better than the old BPs ever were
[23:23:10] <hazzy-lab> `Wolf: Ok, that does narrow it down to the X!
[23:24:18] <`Wolf> 1986 machine, I guess I can’t expect the world out of it lol
[23:25:35] <hazzy-lab> It looks like it has been well maintained, certainly worth putting the time into scraping the X if you need that kinda accuracy
[23:25:44] <`Wolf> blah I broke my 1/2” edge finder… wasn’t paying attention and crashed it in to the vise
[23:26:28] <`Wolf> prior owner made mostly acrylic and aluminum parts
[23:26:57] <`Wolf> mostly really small stuff, electron microscope parts and whatnot
[23:27:38] <XXCoder> ow
[23:27:47] <hazzy-lab> Generally you can put the edge finders back together, sometimes a new spring is needed though, I find springs from a bic pen work well :)
[23:27:50] <XXCoder> mines standard starret one
[23:28:04] <`Wolf> snapped the stem
[23:28:14] <hazzy-lab> All three of my edge finders have bic springs,
[23:29:09] <RyanS> those electronic edge finders suck very fragile

[23:29:20] <`Wolf> skills..
[23:29:40] <hazzy-lab> Hey, that is plenty left!
[23:29:50] <XXCoder> as pictured, it looks HUGGE
[23:29:59] <XXCoder> like one inch diameter or larger
[23:30:28] <`Wolf> yeah no sense of scale lol
[23:31:01] <hazzy-lab> its hard to get the spring to catch with that little left, but you can loop some string though the spring and pull it out so you can get it started,
[23:32:12] <`Wolf> have to ge the stub out firstv
[23:32:35] <RyanS> any difference in use the starret style and this https://www.machineryhouse.com.au I it's easier to see the offset
[23:36:29] <`Wolf> i could go overkill mode and break out the renishaw

[23:42:10] <RyanS> they want the equivalent of $670 USD here
[23:42:58] <`Wolf> eBay score, the MP1s + Mi5 <$200usd
[23:43:59] <`Wolf> even better the mp1 had the 3/4” mount on it
[23:45:02] <`Wolf> it has to be a shop spare, thing didn’t even have the pivot ball in it, was just foam ring between the probe and mount
[23:45:20] <RyanS> i bought a spot drill from the UK, still cheaper than Australia... including postage lol

[23:46:04] <XXCoder> even with crushing shipping prices its still way cheaper.

[23:46:16] <RyanS> granted it was NOS
[23:47:50] <`Wolf> I have my tormach cart with $460 with of stuff in it, trying to make up my mind how much I hate my credit card lol
[23:48:14] <XXCoder> you have it so much, shred it. ;)
[23:48:59] <`Wolf> probably would be a wise move before I max it out w/ tooling lol
[23:49:08] <XXCoder> dammit
[23:49:12] <XXCoder> *hate
[23:49:17] <RyanS> I have some Chinese reduced shank drills, perfectly fine. not paying $ 60 for an Australian made one
