01:47 AM IchGucksLive: morning from windy germany
01:57 AM IchGucksLive: off 2 garden
02:26 AM Deejay: moin
04:09 AM slipalong: Guy's, just having a play with NativeCAD and getting some strange behavior. Its just a simple program to mill around a 180mm X 80mm X 25mm plate and cut a 28mm hole in the middle with a 10mm end mill.
04:10 AM slipalong: II home the axis an touch of the z on top of the work, but no movement and no error messages??
04:12 AM archivist: right mode? did you tell it to run
04:12 AM archivist: does it save the code then you reload?
04:39 AM slipalong: I pressed the run button on gmoccapy but nothing??
04:40 AM slipalong: If I load the spiral example file, even though its in inches it runs fine on my mill.
04:40 AM slipalong: Yes looks ok in the preview
04:45 AM slipalong: i will go and try saving the file and reloading.
04:45 AM slipalong: Its not usually backward is generating error messages!
04:56 AM IchGucksLive: hi from stromy germany
05:04 AM selroc: hi IchGucksLive
05:04 AM IchGucksLive: hi
05:04 AM IchGucksLive: weekend ahead ;-)
05:13 AM IchGucksLive: selroc: are you nearing to a decicion
05:13 AM selroc: ?
05:13 AM IchGucksLive: on the setup of the mashine
05:20 AM selroc: mill
05:20 AM selroc: big spindle
05:20 AM IchGucksLive: 2,2kw
05:20 AM IchGucksLive: watercooled
05:21 AM IchGucksLive: lunchtime here in germany ,till later ;-)
05:25 AM selroc: no its a 3 kw spindle aircooled
05:27 AM selroc: not sure I can run it, it needs 3phase 400V input, so I acquired a big 400V inverter
05:30 AM jthornton: morning
05:33 AM selroc: hi
06:29 AM Tom_L: morning
06:30 AM jthornton: you get any rain over your way?
06:31 AM Tom_L: as we speak yes
06:31 AM Tom_L: and most of yesterday
06:31 AM jthornton: we got a couple of sprinkles and that was it
06:31 AM jthornton: is there an easy way to log into my server from outside the LAN?
06:32 AM Tom_L: i use putty or winscp
06:32 AM Tom_L: you'll have to set up a share iirc
06:32 AM Tom_L: haven't done that very much
06:33 AM archivist: or ftp :)
06:34 AM Tom_L: you might have to open a port on the router for it too
06:34 AM Tom_L: 22?
06:34 AM archivist: these days sftp
06:34 AM jthornton: ok googling all that
06:35 AM Tom_L: sftp is what winspc uses
06:35 AM Tom_L: scp*
07:18 AM slipalong: That was interesting I changed the UI to AXIS and did the homing / touch off and it ran the same g code no problem???
07:27 AM jthornton: I think I've screwed up my ubuntu server lol
07:42 AM FabLab: Hi peps
07:47 AM FabLab: hi I search a lowcost spindle for a pcb mill
07:49 AM jelly-home is now known as jelly
07:50 AM archivist: lower cost and better to get PCBs made in china
08:00 AM SpeedEvil: https://www.youtube.com/watch?v=wwMDvPCGeE0 replacing an axis.
08:00 AM SpeedEvil: IN SPAAAAACE!
08:01 AM SpeedEvil: (they are replacing the end effector on the robot arm on ISS, which will take abou 6 hours total)
09:16 AM IchGucksLive: hi full rain in germany
09:16 AM IchGucksLive: FabLab: you can take the aircooled 800W
09:17 AM IchGucksLive: if you need mutch lower cost go for proxxon
09:18 AM IchGucksLive: archivist i fully agree on pcb but the deliver time of 8weeks may not be the best
09:19 AM IchGucksLive: SpeedEvil: http://www.ustream.tv/nasahdtv
09:22 AM IchGucksLive: later ;-)
09:46 AM HighInBC: I don't think china pcb's are lower cost, a blank board is what $1 for a big one?
09:46 AM HighInBC: your personal time has value of course, but waiting several days minimum for even a rush order is also using your time
09:46 AM HighInBC: higher quality for sure
10:05 AM Loetmichel: *AUTSCHN*... "MIPFT!" Note to self: Brass sheet, heatet do release temp of the double sided tape will STAY hot a while, even if its only 0.3mm thick... *sucks on finger*
10:06 AM gregcnc_: no gloves in PPE cabinet?
10:06 AM Loetmichel: ppe?
10:07 AM Loetmichel: ah, personal protection equipment
10:07 AM Loetmichel: yes, i have
10:08 AM Loetmichel: to lazy to get it... waving around with a gas torch over the CNC vacuum bed isnt really "safe" anyway though ;)
10:08 AM gregcnc_: did you also mist ethanol?
10:09 AM Loetmichel: not this time luckily :)
10:09 AM gregcnc_: lolz
10:10 AM Loetmichel: heating the brass when releasing from the tape on the table saves a lot of cleaning work on the brass foild afterwards though.
12:14 PM IchGucksLive: hi
12:21 PM IchGucksLive: FabLab: still online
12:25 PM FabLab: hi sorry
12:25 PM FabLab: Online but working in my fablab
12:26 PM FabLab: I got linux cnc to work with steppers
12:26 PM IchGucksLive: cool
12:26 PM IchGucksLive: for spindlke get as mutch speed as you can
12:26 PM IchGucksLive: no need to go beond 800w
12:27 PM IchGucksLive: FabLab: where in the world are you
12:28 PM IchGucksLive: europ usa asia
12:28 PM chris_: uk
12:28 PM chris_: I have some questions I would like to ask
12:29 PM jdh: ask
12:29 PM chris_: never used irc before
12:29 PM IchGucksLive: we are all here to help you
12:30 PM chris_: I'm trying to install lcnc onto a five axis unit (nikken) on a VMC with a Fanuc oi-mc control
12:31 PM chris_: I get postion from the control via RS232 and I want to set the position of the A and B axes with lcnc
12:32 PM IchGucksLive: cris this one https://www.youtube.com/watch?v=e3LMm4krXas
12:32 PM FabLab: DARMSTADT
12:32 PM IchGucksLive: FabLab: ich sitze in zweibrücken
12:34 PM chris_: just having problems setting lcnc up with only an A and B Axes - it's not five axis just 3+2 positional
12:34 PM IchGucksLive: chris_: did you get the position from the control or from the cabinett controll board
12:35 PM IchGucksLive: chris_: this is uncomen why woudent you let lcnc do all the stuff
12:35 PM chris_: yes I use dprnt commands though the 2nd rs232port on the fanuc control
12:36 PM chris_: the machine uses fanuc drives etc which are not compatible with lcnc
12:36 PM IchGucksLive: but the fanuc drivews can be driven by the mesa 7i77
12:37 PM IchGucksLive: so you got a full controlld mashine by lcnc
12:37 PM chris_: the macine is a 2007 model and uses beta drives which are digitally contrlled
12:38 PM IchGucksLive: so it is the 0i mathe drives
12:38 PM chris_: the xyz axes are controlled by the fanuc contrller
12:39 PM IchGucksLive: the thinkiing is then you ony got a 2,5D mashie with extra
12:39 PM chris_: I have researched interfacing to the fanuc drives and apparently it can't be done
12:40 PM Loetmichel: has anyone seen the AoE video about chatter prevention btw?
12:40 PM Loetmichel: does that really work with a few 100 rpm variation?
12:42 PM IchGucksLive: chris_: you only need to replace the encoders with quadradure
12:43 PM IchGucksLive: Fanuc Servo Amplifier, A06B-6058-H334, A16B-1100-0330/03A for the axes Fanuc 6S A06B-0315-b003#7000 motors on the axes THIS will work
12:44 PM IchGucksLive: but i think since lst year there is also a serial communication with the fanuc controler posible
12:44 PM IchGucksLive: chris_: let me search
12:44 PM IchGucksLive: chris_: there we go http://linuxcnc.org/docs/2.7/html/man/man9/hostmot2.9.html#Fanuc%20encoder.
12:45 PM chris_: that would be great if I could do that. but in the meantime I it possible to set up lcnc with only a and b axes
12:46 PM IchGucksLive: do it by hand and test it
12:46 PM IchGucksLive: it shoudt work
12:46 PM IchGucksLive: let me get a test
12:47 PM Tom_L: IchGucksLive, you use these to build machines: http://www.ebay.de/itm/EU-6Pcs-Square-Linear-Rail-Guide-L-400-700-1000mm-Ballscrew-1605-400-700-1000mm-/152680647211
12:47 PM Tom_L: ?
12:48 PM chris_: Ive done that but I get and error when I run it :- emcTrajSetAxes failing axes=2 axismask=18
12:49 PM IchGucksLive: Tom_L: yes it is on this mashine https://www.youtube.com/watch?v=BzqN-yL2LGs
12:49 PM Tom_L: can you cut steel with em?
12:49 PM IchGucksLive: hi Marlon_1337
12:49 PM chris_: I am using the pico USC board that Ive used on several machines with no prolem
12:49 PM Marlon_1337: hi IchGucksLive :)
12:49 PM IchGucksLive: Tom_L: not on my mashine set up
12:50 PM Tom_L: just wondered if the rails would support it
12:50 PM IchGucksLive: for steel i woudt go the way on movinfg table
12:50 PM Tom_L: no
12:51 PM IchGucksLive: Tom_L: this will give you FE support https://www.youtube.com/watch?v=AaJZiEVWwME
12:51 PM IchGucksLive: eben on sbr20
12:52 PM IchGucksLive: hi gloops
12:52 PM Tom_L: that one yours too?
12:53 PM gloops: hi Ichs/all
12:56 PM Loetmichel: does anyone have blueprints to make a "$5 car tire inflator" sized vacuum pump? (for replacement in a desoldering station)
12:57 PM Tom_L: no but i used a fishtank pump for a pick n place suction thingy
01:04 PM Loetmichel: not enough suction
01:04 PM Loetmichel: such a constructin is now in place there
01:04 PM Loetmichel: i need more volume and more instantaneous to free the THT leads
01:07 PM IchGucksLive: chris_: the setup AB workes here all motors are runnung without a XYZ config
01:10 PM gloops: they use those diy pumps for degassing silicone
01:11 PM gloops: the one with the plastic reed valve
01:11 PM IchGucksLive: chris_: there is no problem on lcnc Version 2.7.9 + with joints to setup ypur system as you like
01:11 PM IchGucksLive: chris_: be aware of aenable
01:12 PM IchGucksLive: you can only use the joints you got in setup
01:12 PM IchGucksLive: chris_: joint config starts at 0
01:12 PM gloops: how do you do it now - just cap the intake valve with a boss that takes a tube
01:13 PM chris_: IchGucksLive: thanks I will try again , thanks for the info on the facnuc stuff I will look into this futher
01:14 PM IchGucksLive: chris_: i set up a mashine here on my side and it worked right off
01:17 PM gloops: it takes ages to get a vaccum, they generally vacuum a tank then tap off that
01:17 PM IchGucksLive: gloops: use your wives cleaner
01:17 PM gloops: http://www.instructables.com/id/convert-a-tire-inflator-type-air-compressor-into-a/
01:17 PM gloops: Ich no good it wont hold the pressure
01:17 PM IchGucksLive: then get to the next porsche junk yeard and use the pump of the car
01:18 PM IchGucksLive: the new one is 50usd
01:19 PM IchGucksLive: gloops: out of the bay 131539365847
01:19 PM gloops: yeah there probably a lot better things to use than a tyre inflator, a bigger compresser is needed
01:19 PM gloops: <Loetmichel> does anyone have blueprints to make a "$5 car tire inflator" sized vacuum pump? (for replacement in a desoldering station)
01:20 PM IchGucksLive: gloops: there are also 12V parts
01:20 PM gloops: i looked at making one a while ago to degas rtv silicone - removes any air bubbles in the mold
01:21 PM Loetmichel: gloops: i used that to describe the size, noting more
01:21 PM IchGucksLive: im off Thanks for the TALK all here Gn8
01:22 PM chris_: bye
01:23 PM gloops: that is cheap for a vacuum pump theyre usually more than a compressor
01:24 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16679&g2_imageViewsIndex=1 <- middle of the picture you can see what pump is installed now
01:24 PM Loetmichel: its a "double diaphragm" fish tanl type pump
01:25 PM Loetmichel: and has not enough volume by far.
01:26 PM Loetmichel: i have a lathe and a CNC router... i just need a few ideas how to do a vacuum pump with more volume driven by the same motor
01:33 PM * JT-Shop just had a tab ruin a 2.5" shell mill... only $150 for the tab key and some really ugly vise jaws
01:44 PM JT-Shop: oh and can't forget the $50 worth of inserts!
01:54 PM FinboySlick: Loetmichel: magnetically supported and driven impeller running at 100krpm.
01:55 PM Loetmichel: FinboySlick: improbable in that space. also : waaaay to slow to start
01:55 PM Loetmichel: to have best result when desoldering the vaccum should be at full "suction" in the shortest possible time
01:57 PM HighInBC: for quick response you can pre vacuum a chamber then open a valve to the chamber
02:01 PM FinboySlick: http://www.skf.com/binary/21-121449/13624-EN---Magnet-motor-solutions.pdf is what I had in mind.
02:21 PM miss0r: I just managed to get a realy good deal on a technician to come take a look at the backlash issue in my mill this saturday. And I got it for a bargin :]
02:24 PM gloops: miss0r probably the best move if you cant determine the problem yourself, once you start replacing random bits you guessed at things can end up costing a lot more
02:25 PM gloops: Loet you gotta have a tank for that, hold the vacuum in the tank for when you need it
02:26 PM miss0r: Yeah, I made the decision after after finding that the ballscrew on the x-axis (not including the ballnut or axial bearings on the end) would set me back more than 3k usd
02:28 PM miss0r: this guy 'only' takes 150$/hour. so i'll see what he has to say. and I hope he doesn't stay long. my shop barely passes the hobby/pro shop line
02:28 PM gloops: well, i hope its nothing big
02:29 PM miss0r: So right now i'm stripping down the skirts, so he won't have to do it for 150$/hour.. :)
02:29 PM SpeedEvil: :)
02:29 PM miss0r: Me neither. Especially considering I only payed 1500$ for it
02:29 PM miss0r: but that was an insane price, I know.
02:29 PM sync: nah, not really, the mahos often go for prices like that
02:30 PM gloops: yeah good idea, make it easy..and quick for him
02:30 PM sync: almost all old slideway machines do as they are worn most of the time
02:30 PM miss0r: It seems that might be the case with mine as well... :-/
02:30 PM miss0r: I can't wait until Saturday. I need closure here :]
02:31 PM gloops: worst case scenario?
02:32 PM miss0r: But he also mentioned the possibility of replacing the balls in the nuts with oversized ones to somewhat compensate for wear - That sounds more like something I can afford than a new assembly
02:32 PM miss0r: gloops: Worst case is I might be having a ridiculously large paperweight on my hands
02:32 PM gloops: yeah thats what we said - everybody fits the oversize balls
02:32 PM miss0r: yeah
02:32 PM sync: I would just get a new spindle assembly if it is the broken part
02:33 PM gloops: you can still sell it miss0r
02:33 PM gloops: dont buy a new screw, get another mill
02:33 PM miss0r: But I don't want to. i've grown accustomed to it :]
02:33 PM sync: well, if it is in good shape generally getting a new screw is cheaper
02:34 PM sync: as you know the state of repair
02:34 PM gloops: and stripping the nut isnt a 5 minutes job either
02:35 PM miss0r: sync: I'm hoping to keep it without replacing the nut/screw. Refurbishing it would be nice thou
02:36 PM miss0r: gloops: The x-axis is pretty accessible. I'm still trying to figure out how to expose the y-axis screw
02:36 PM miss0r: I just want his opinion on the state of the machine. He comes well recommended. Then I will re-ball the nuts myself if that is a solution
02:37 PM miss0r: i'm not kidding when I say money is an issue in this shop. So; whatever I can do myself with some degree of certainty I will do
02:39 PM * JT-Shop thinks the end mill pulled out of the holder a bit and ruined the part and the vise stop...
02:40 PM miss0r: :-/
02:40 PM miss0r: Any maho experts in here? I can't seem to figure out how to expose the y-axis screw short of lifting off the ram
02:41 PM gloops: facebook group - home machine shop - you in there?
02:42 PM miss0r: I don't have a facebook acount
02:44 PM andypugh: Sorry, I just did a google images search for “Maho” and got distracted by planes and girls in bikinis.
02:45 PM miss0r: damn - looking at it, it realy doesn't seem like I can do it wouthout removing the ram... I have no way of lifting that
02:45 PM gloops: always a way, how heavy?
02:46 PM miss0r: Its hard to say. I would guess alot.
02:46 PM andypugh: Weld a frame to clamp to the Z to lift the ram with the Z screw.
02:46 PM miss0r: the ram includes the gearbox, spindle motor ect.. and it is pretty massive
02:46 PM gloops: any mates who mess around with cars? little portable engine hoist
02:47 PM andypugh: I am guessing something like this? http://dirkvdh.weebly.com/uploads/1/7/0/1/17018852/3893862_orig.jpg
02:47 PM miss0r: gloops: I have one of thoes, but I wouldn't be able to fit it in here. room is tight
02:47 PM miss0r: andypugh: Close, yeah
02:47 PM * JT-Shop cuts off some more way too big stock and gives up on getting anything else done today
02:48 PM * miss0r pets JT-Shop.
02:48 PM miss0r: You can come help me with this then ;)
02:48 PM andypugh: I like that design, like the Huron and Deckel.
02:48 PM miss0r: andypugh: Deckel ended up buying Maho. The later models are called Deckel Maho
02:48 PM andypugh: Reminds me, anyone have a Deckel FP2? There is a slotting head on eBay.
02:49 PM gloops: well if no space, just have to jack it up on wood chocks
02:49 PM gloops: you cant beat wood
02:50 PM andypugh: What is your ceiling made of? Hole through the ceiling and spreader beam?
02:50 PM gloops: good idea, or forklift over the top
02:50 PM miss0r: The day the maho moved in: http://picpaste.com/IMG_0339-RSKYgLhZ.JPG
02:51 PM miss0r: yes, thats my bald head in the background
02:51 PM andypugh: I hang my vertical head from the ceiling on a chain winch: https://photos.app.goo.gl/mCbHweSmuCi4IOp93
02:52 PM * JT-Shop wants to go play with the chickens instead of trashing face mills, exploding end mills, wrecking vise jaws and ruining parts...
02:52 PM andypugh: Sounds like time to share abeer with the chickens.
02:52 PM miss0r: I guess my ceiling could hold the weight. I build it with 3x6" beams. with 450mm spacing
02:53 PM gloops: would if you drop a length of box section across 3 or 4 of them to hang some pull lifts on
02:54 PM miss0r: I actualy have an I-beam outside, i've been planning to have running at an angle underthe roof here. Serving the mill and the lathe. Why-oh-why haven't I installed it yet
02:54 PM andypugh: Sounds like now is the time.
02:55 PM JT-Shop: Andy has the best idea so far
02:56 PM miss0r: It realy does. but i'm not sure I can have that done by Saturday (being a father and husband as well)
02:57 PM miss0r: another thing. The ram has dovetails. I think it needs to be pulled and lifted at the same time
03:00 PM miss0r: http://picpaste.com/IMG_1316-ODloMvZy.JPG http://picpaste.com/IMG_1313-9kDz4kf0.JPG (Pictures from yesterday, before I started tearing it down) As you can see, I haven't got alot of room left to maneuver in
03:04 PM andypugh: Is there a taper gib or screw-gib on the dovetail? Sometimes you can simply lift-off a slide with the gib removed. (and sometimes you can’t)
03:05 PM gloops: well, although it isnt strictly true to say wood is stronger than steel, in the portland tests wood compared very favourably with steel for structural support
03:07 PM miss0r: andypugh: It does have a gib in there, but too small to allow for that clearance
03:08 PM andypugh: I know this is a very different machine, but it shows the screw below the dovetail at the back (looks like rotating-nut). Is yours perhaps the same? http://www.lathes.co.uk/maho/page2.html
03:09 PM andypugh: In which case you unbolt the screw-bracket and slide the head forwards.
03:09 PM miss0r: yes. it also has a rotating nut. but I fear that is part of what he want exposed
03:10 PM miss0r: i'll try to remove the cover in the back. I'm hoping that will do
03:12 PM Marlon_1337: Could someone pls tell me how to increase jog speed in mach3? I have accel and velo as high as possible, but when jogging with virtual mpg the axis only move very slow, like 1 step per 30 seconds . MPG Feedrate is 100, the box in the wheel says 100% too. Can't figure out what i am doing wrong :(
03:14 PM Marlon_1337: actually using, linuxcnc but i forgot my laptop at home :D
03:14 PM andypugh: Marlon_1337: Well, clearly the answer is to upgrade to LinuxCNC. It might not work any better, but we will at least be able to answer more intelligently.
03:15 PM gloops: i tried mach3 once, the mrs ended up going for 24 cans for me
03:15 PM Marlon_1337: Hahah, yes i know. Just forgot my Laptop at home, so no linuxcnc today :(
03:16 PM Marlon_1337: Hahaha, you have to see how my gui looks like :D the numbers don't even fit in the boxes ^^
03:16 PM Marlon_1337: ok, going to setup a VM running ubuntu.
03:17 PM andypugh: That won’t run the machine, though.
03:17 PM Marlon_1337: anyone has experience how high SLAT latency from VM to parallel port will be? Do you think realtime is possible?
03:18 PM JT-Shop: http://gnipsel.com/images/misc/parts.jpg
03:18 PM andypugh: Maybe the mpg scale needs to be 0.001 rather than 100?
03:19 PM andypugh: My VMs run at hundreds of mS latency, not a chance of being useful.
03:19 PM Marlon_1337: damn -.-
03:20 PM andypugh: JT-Shop: I like the second part, it is more expressive and nuanced. :-)
03:20 PM JT-Shop: I should have put all the damaged tooling in the photo!
03:23 PM JT-Shop: I think I've spent too much time as of late with a hammer in my hand instead of file
03:23 PM gloops: Marlon what kind of speeds do you want?
03:23 PM gloops: ipm say
03:27 PM Marlon_1337: like 10 in/min , but i will try with VM and ubuntu now
03:28 PM Todd_Z: Just resize the partition on your Windoze Mach3 computer a bit and instal Linuxcnc beside it (duel boot).
03:30 PM gloops: 10 inches per minute???
03:30 PM Marlon_1337: Yes, it is more for moving some parts in my garage than for real CNC
03:30 PM miss0r: andypugh: That did the trick. as in the picture. I now have access to the rotating nut and the ballscrew :D
03:31 PM miss0r: Marlon_1337: never the less. that might very well burn your tooling out
03:31 PM miss0r: JT-Shop: What the hell happened?
03:32 PM miss0r: JT-Shop: Did you loose your z-refrence?
03:32 PM Marlon_1337: there is no tool :) . It is just a rod moving Boxes
03:32 PM Marlon_1337: i am not milling anything with it
03:32 PM miss0r: nvm me
03:33 PM gloops: well, suppose it depends on the weight of the boxes 60 ipm is a comfortable speed for freight
03:36 PM gloops: 200 would be better
03:36 PM Marlon_1337: by the way. Has someone already built a robotic arm using linuxcnc?
03:39 PM gloops: https://www.youtube.com/watch?v=G_UmhUjZhNo
03:41 PM Marlon_1337: omg, so cool <3
03:51 PM * JT-Shop is reminded again how bad OneCNC is...
03:51 PM JT-Shop: watching the mill cut a lot of air!
03:52 PM gloops: the thing with speed, it isnt just a case of some theoretical value. this mm per minute or that mm per minute, there are physical considerations too
03:53 PM andypugh: Marlon_1337: Several. https://youtu.be/O2oaBtkpNpE
03:53 PM tiwainjo: I'm looking for someone who knows about the Mechatrolink protocol
03:54 PM tiwainjo: Or if people have suggestions on how to synchronize several servos together other than using Mechatrolink protocol
03:55 PM andypugh: tiwainjo: Searching here http://www.linuxcnc.org/search/ for mechatrolink gets you a couple of hits.
03:56 PM andypugh: I got a flyer yesterday saying that DMM servo drives now have a CAN option.
03:57 PM andypugh: http://www.generalmechatronics.com/en/linuxcnc has LinuxCNC-supported cards that run CAN
03:57 PM tiwainjo: yes CAN can be a good way to synchronize, but what if you want really high levels of synchronization?
03:58 PM andypugh: DMM also support ModbusRTU http://dmm-tech.com/Dyn4_main.html
03:59 PM miss0r: i've seen stuff on this mill now.... The gib on the y-axis is actualy tightened all the way, and theres still a little bit of wiggle... 0.05mm at full ram lenght. but I can't tighten the gib anymore... So when the mill is back up and running, I will make some sort of extention to it - assuming the oil wells on it allows for it to be move more than it already is
03:59 PM andypugh: Well, I would probably use analogue voltage control and encoder feedback back to LinuxCNC, because that’s a technology I understand.
04:00 PM andypugh: miss0r: Is it a tapered gib?
04:00 PM miss0r: yeah
04:00 PM andypugh: A flat shim on the back of the gib might be easier. Maybe pinned at one point.
04:00 PM tiwainjo: @andypugh thanks for the links and sharing your mind on this, will look into it
04:01 PM miss0r: I already cut of a little of the end, as the previous owner had tightened it all the way, resulting in the end of the gib pushing on the back of a way wiper in one end.
04:01 PM miss0r: the shim will be dificult: theres alot of lubrication going on inside that gib
04:02 PM miss0r: hehe... with all the skirts removed, this is actualy a quite skinny lady :]
04:03 PM miss0r: the mill has 35 lubrikation points handled by the ALS
04:03 PM miss0r: more than I thought to be honnest
04:08 PM Loetmichel: *brrr* whoever did the central heating pipes in this house in the 70ies never heard of "decoupling hot water pipes from the walls"... just had to restart the furnace (natural gas)... now its like a horror house... 5 different directions, 5 different sounds... *BRRRRRRRRRR* *KNAAAARZ* *TockTockTockTockTockTockTockTock* *Tock......Tock......Tock* *TikTikTikTikTikTik* :-(
04:09 PM andypugh: I refuse to turn on my heating until the clocks change :-)
04:10 PM gloops: sounds like the system needs bleeding Loet - trapped air
04:11 PM JT-Shop: it's 28C here take some of my heat
04:11 PM miss0r: I'll gladly do that. Here its 8c
04:13 PM * JT-Shop needs to figure out how fusion 360 works I think if it does better tool paths
04:13 PM miss0r: I should realy clean out the coolant tank while being in here... Its pretty hazardous
04:14 PM miss0r: JT-Shop: What mill are you using there?
04:15 PM Loetmichel: gloops: no, missing the "slide cloth" around the copper pipes before embedded into the walls with plaster
04:15 PM Loetmichel: its the pipes moving in the plaster while heating up, not trapped air
04:15 PM Loetmichel: it vanishes the moment the heating system has "thermal equilibrium"
04:16 PM Loetmichel: and appears again when the furnace cools down and restarts the burner
04:20 PM gloops: we dont plaster heating pipes in in this country, as a rule
04:22 PM Loetmichel: here they are in the walls as a rule
04:22 PM Tom_L: JT-Shop, you gonna start holding f360 class?
04:22 PM JT-Shop: BP Discovery 308 today
04:22 PM Tom_L: btw, those parts don't look the same
04:22 PM JT-Shop: I don't get fusion 360 yet
04:22 PM Loetmichel: or, lately in the styrofoam below the screed
04:22 PM JT-Shop: I noticed that...
04:22 PM Tom_L: it's in it's infancy so i hear
04:23 PM Tom_L: several gotchas
04:23 PM Tom_L: i haven't tried it but have been waiting
04:23 PM Tom_L: JT-Shop get anywhere on your sftp connections?
04:23 PM miss0r: JT-Shop: I can only envy that amount of internal memory :) it makes better toolpaths an option
04:24 PM JT-Shop: Tom_L: gave up when the server can't upgrade anymore
04:24 PM JT-Shop: miss0r: in the 308?
04:24 PM Tom_L: 10.04?
04:25 PM miss0r: yeah
04:25 PM miss0r: doesn't it have like 600 something kbytes?
04:25 PM JT-Shop: it's just got a 386 processor... hmm I don't know
04:28 PM miss0r: I'm not even sure what processor mine has. probally a 8086. sporting the mindblowing 80kb of memory. only 64kb open for g-code input
04:30 PM Deejay: gn8
04:30 PM miss0r: nn
04:32 PM JT-Shop: wow an 8086! my first pc was an 80286 with 640k memory
04:34 PM miss0r: mine as well. Atleast boot time is not an issue with this controller. The slowest part (by far) is the crt monitor
04:36 PM Tom_L: hah, i think my 8088 is still in the closet somewhere...
04:38 PM JT-Shop: well I'm back where I was at 13:02 but with a finished good part and another on in the mill
04:38 PM miss0r: I regret throwing out my IBM PS/2 286 pc... I realy think I would have fun messing with it
04:38 PM enleth: miss0r: about the shim - my bridgeport has lubrication paths through the gib itself and it works well, so a shim with some countersunk holes matching up with existing orifices should not interfere with lubrication at all
04:38 PM Tom_L: still raining too...
04:39 PM miss0r: enleth: I guess. I will look into that, no doubt. I still believe this mill has a future here. After stripping it down, and giving it a rudimentary cleaning I fell back in love with it
04:40 PM Tom_L: my server was dontated from somebody's trash can and i don't even know what cpu it has
04:40 PM miss0r: how can you not? :S
04:40 PM Tom_L: been running for several years
04:41 PM Tom_L: 16:41:09 up 283 days, 3:44, 1 user, load average: 0.14, 0.05, 0.06
04:41 PM miss0r: I have a dual xeon 54xx something (6 cores at 2ghz + hyperthreading/CPU) with 64gb memory laying around. Anyone interrested?
04:41 PM enleth: miss0r: IMHO if you want to do anything with a machine this old - unless it's been sitting in a warehouse full of factory grease - you really have to be able to take it apart completely and put it back together, and do it at least once after you get it
04:42 PM enleth: miss0r: assume nothing of the previous owners, for one
04:42 PM miss0r: Tom_L: less /proc/cpuinfo
04:42 PM Tom_L: miss0r for what? to sit around counting wait states?
04:42 PM Tom_L: celery... err celeron
04:42 PM miss0r: :]
04:43 PM miss0r: enleth: That is true. What I normally do. I was just a bit scared of its complexity. Thoes linear glass scales frighten me
04:44 PM miss0r: Tom_L: You can use it for whatever. I used to run it as a desktop PC, till I started getting worried about the electrical bill
04:45 PM sync: The scales are not too much of an issue
04:45 PM miss0r: not realy. but it was completely new to me.
04:46 PM miss0r: I'm still flirting with the idea of doing a retrofitting of it. But I have only found one seller claiming to be able to translate the signal from thoes old philips heads to something I can feed into a modern controller.
04:46 PM miss0r: and they are expensive
04:46 PM Jymmm: Does anyine have any info/links to creating your own (like laptop display) backlights? Specifically the thing even distribution of light thru the panel from an led light source at the edge?
04:47 PM enleth: miss0r: a friend is going to be moving a bridgeport similar to mine cross country later this year, he's never taken it apart before and it's got some problems; I managed to convince him to take it apart for shipping and then finish the job to the last screw to clean it up and replace some parts, the machine will be better off that way
04:47 PM Jymmm: thin*
04:47 PM * JT-Shop gets his 5 o'clock beer
04:47 PM enleth: miss0r: as for the read heads - you might be able to use the original resolvers
04:47 PM Jymmm: JT-Shop: you're late =(
04:47 PM JT-Shop: enleth: what kind of bp?
04:48 PM miss0r: Jymmm: I've done it. its realy easy
04:48 PM enleth: JT-Shop: Interact I, mine is/was (it's heavily modified by now) Series I MDI
04:49 PM enleth: JT-Shop: same cast parts except for the ones that accomodate handwheels on MDI
04:49 PM miss0r: enleth: That is also an option. I was aiming for a solution where I would be able to do a plug'n'play swap between thoes two controllers. so removing the resolvers from the old controller would somewhat defeat that purpose
04:49 PM Jymmm: miss0r: do tell, feel free to PM
04:49 PM * JT-Shop is glad it's Friday
04:49 PM enleth: JT-Shop: it looks pretty different externally, but that's due to the blocky decorative covers on the ram/head assembly, underneath both are exactly the same
04:50 PM Jymmm: JT-Shop: Um.... "me too" ;)
04:52 PM enleth: miss0r: you don't necessarily have to remove them completely
04:52 PM enleth: miss0r: are they actually separate modules/PCBs inside?
04:52 PM miss0r: yes. well.. all three axis are handled by the same plugin card
04:53 PM enleth: miss0r: are the scales absolute?
04:54 PM miss0r: yes
04:55 PM enleth: ok, afraid I won't help much, that's pretty much outside of my experience - so far I've dealt with incremental encoders
04:57 PM enleth: if the control is anything like my old Heidenhain, the card probably stores position values locally and is accessed by the main CPU over the main memory bus as a mapped periphery
04:57 PM enleth: not exactly trivial to work with
04:59 PM miss0r: What I seem to read everywhere, yes
