12:02 AM Crom: Stuck a 9" sanding disc adhesive back onto a hunk of the flycut coldrolled that I used a parallel to check for flatness, works a treat for lapping
12:05 AM Crom: Nice 18mm thick pice
12:05 AM Crom: pece
12:09 AM Crom: piece
12:09 AM pink_vampire: Crom: what are you trying to do?
12:11 AM Crom: Had a A/C clutch come in today to the shop. Pressed it apart, stuck the pulley and friction face in the lathe and made it pretty flat, I then lapped them on the coldrolled to check for cupping, very little... lapped them until I had 85% contact or better. Trimmed a spacer to get the 1mm gap
12:12 AM Crom: Had to trim the spacer 1.3mm
12:12 AM pink_vampire: is that for a lathe?
12:13 AM Crom: The clutch was for a pump, but it's basically a A/C clutch
12:15 AM Crom: We tore apart a Denso Alternator testing machine last night and we got 2 really nice pieces of coldrolled. 3/4" had the motor mounted on it, and the deck was a 5/8" piece
12:16 AM Crom: 3/4 was like 21" x 18" and the 5/8" was 30" x 40"
12:20 AM pink_vampire: mmmm
12:31 AM Loetmichel: mornin'. MUCH better. Still have pain when coughing, but i think thats just sore muscles from coughing, no more pain in the windpipe and no more fever... coffee, off to work... i like the fact that i shrug off a cold so fast ;)
12:31 AM fragalot: :-)
01:19 AM IchGucksLive: morning from Carnival getting started Germany
01:20 AM IchGucksLive: Loetmichel: did you got a site to start building a Rectangle Freq generator 5-250kHz
01:34 AM IchGucksLive: morning gloops
01:34 AM gloops: hello
01:35 AM fragalot: hey
01:35 AM IchGucksLive: Loetmichel: got a good system http://www.dieelektronikerseite.de/Projects/Funktionsgenerator.htm
01:36 AM gloops: just checking prices for some bigger steppers
01:38 AM fragalot: gloops: before, or after diagnosing the issue you have?
01:39 AM gloops: im not buying them yet fragalot, i will look at the problemfirst, and i want everything else proven to be working before i invest much more
01:40 AM gloops: ideally though 6Nm + and closed loop for the gantry
01:40 AM fragalot: don't forget that you'll also need larger drives, and a larger power supply
01:40 AM gloops: ill run it slower for a while to see if it is worth investing in
01:40 AM gloops: yeah, ive got a 60v power supply, they usually come with a driver
01:41 AM fragalot: it's not just the voltage gloops, it's also the current
01:41 AM fragalot: if the power supply can't keep up, it doesn't matter what motors you have
01:42 AM gloops: right, ill check that too, im going to investigate what is happening while this gantry is running / power use
01:42 AM IchGucksLive: gloops: you got enoph power beleve me 3Nm is way hevy
01:42 AM Wolf__: 6Nm is big
01:42 AM fragalot: That's why I went for 8Nm. :P
01:42 AM IchGucksLive: 4Nm are Best price Torque and Ampere
01:42 AM gloops: Ichs thats what i thought, but it isnt givng too much on the gantry
01:43 AM fragalot: IchGucksLive: none of the specs matter if there is a power issue though
01:43 AM gloops: on my old machine, 1 motor drove the gantry and it was moving at 15m/m with the chain
01:43 AM Wolf__: my 2.65Nm motors are 470W
01:43 AM fragalot: so until gloops manages to check everything over and confirm that at least the power is OK, everything is speculation.
01:43 AM gloops: 2 motors pushing this gantry should be adequate, 6Nm combined
01:43 AM IchGucksLive: fragalot: i run a 6Tonn mashine Gantry on a 8Nm with 48x8mm Trapezional
01:44 AM fragalot: IchGucksLive: it does NOT MATTER what the specifications are if the POWER SUPPLY CAN NOT KEEP UP.
01:44 AM IchGucksLive: Agree
01:44 AM gloops: i might get 30 minutes this morning, otherwise probably be the weekend or tonight
01:44 AM fragalot: IchGucksLive: say you have a 12Nm motor that requires 8A to run, but your power supply only manages to give it 4. How much torque does it really give?
01:44 AM IchGucksLive: 1/16
01:45 AM gloops: it is the symptoms of power drain, motor stalling at high demand
01:45 AM IchGucksLive: if your cable extends 2meter you need to double the Voltige
01:45 AM fragalot: or use thicker wires
01:45 AM gloops: they are nowhere near their max rpm
01:45 AM IchGucksLive: gloops: stat to get the system UP at 1200mm/min
01:45 AM IchGucksLive: start
01:45 AM fragalot: at work we often use 10mm² cables for a 6A load to compensate for voltage drop..
01:46 AM gloops: i cant double the volts the drivers restrict it to 50v
01:46 AM gloops: Ichs it runs fine at 2000mm/min
01:46 AM IchGucksLive: are you on 48V
01:46 AM gloops: maybe that is its max
01:46 AM gloops: 36v psu
01:46 AM IchGucksLive: 2m is ok at your size
01:47 AM IchGucksLive: gloops: your dirvers got a DIP 4 for Half power
01:47 AM gloops: well, i will take the big pulley off and drop the gear ratio, i can get 2000mm with more holding torque
01:47 AM gloops: Ichs yes - tried them on and off
01:48 AM IchGucksLive: i told You 400Steps/R on the stepper and 20/25
01:48 AM gloops: i have got 2 psus - im going to put X motors on 1 alone
01:48 AM IchGucksLive: ypu need to unplug the Parport cable to set DIP
01:48 AM Wolf__: also take china stepper specs with grain of salt
01:48 AM gloops: i will change to 20-25
01:49 AM MrHindsight: -18C again
01:49 AM fragalot: Wolf__: blasphemy.
01:49 AM IchGucksLive: Wolf_ Fully Agree
01:49 AM fragalot: Wolf__: The chinese are providing us with cheap shit and you DARE to question them?
01:49 AM IchGucksLive: M542.. is shit
01:49 AM gloops: if it is just underpowered motors its an easy fix later, and closed loop is really the best idea for a dual motor axis
01:49 AM MrHindsight: Chinese Nm
01:49 AM IchGucksLive: Leadshine M542 the only thing that copunts
01:50 AM IchGucksLive: or if you got budget the M860
01:50 AM fragalot: MrHindsight: NewtonFeet. :P
01:50 AM IchGucksLive: M880
01:50 AM IchGucksLive: M556
01:50 AM Wolf__: 2.65Nm peak, 12A DC, 470W is one of the servo I have here
01:51 AM gloops: what pitch screws though Wolf?
01:51 AM Wolf__: thats raw motor spec
01:52 AM IchGucksLive: oh i use Nema24 4Nm 2.4V 3A 8mm Shaft Most
01:52 AM IchGucksLive: at 36Euros
01:52 AM fragalot: Hard to beat that price.
01:52 AM Wolf__: but thats a nema 34 servo running a 190v DC bus
01:52 AM IchGucksLive: this realy got power at 72V Supply over 7meter cable length
01:53 AM gloops: if i buy new motors ill go up a lot, at least double
01:53 AM IchGucksLive: gloops: Hardware is counting not electronics in first place
01:54 AM gloops: well the frame and bearings seem fine they arent a problem so far
01:54 AM IchGucksLive: only sculping needs High VCC
01:54 AM IchGucksLive: on standard work keep it to 0,5mm to max speed
01:54 AM IchGucksLive: and use G64 P0,05
01:55 AM IchGucksLive: with best accuracy
01:55 AM IchGucksLive: for rouphing cganging G61 on G41
01:56 AM IchGucksLive: or Drill
01:56 AM IchGucksLive: gloops: did you run my testings
01:56 AM gloops: Ichs no didnt get to doing the tests was looking at motors stalling too long
01:57 AM gloops: just got pulleys fixed, now theyve got to come off
01:57 AM Wolf__: what step divider are you trying to run at?
01:57 AM IchGucksLive: im off BYE
01:57 AM Wolf__: to many steps will mess with torque
01:58 AM gloops: gooday
01:58 AM gloops: 400 steps
01:58 AM fragalot: gloops: why do the pulley sneed to come off again?
01:58 AM gloops: fragalot to reduce gearing
01:58 AM fragalot: leave everything as it is now
01:58 AM fragalot: measure the power supplies
01:59 AM fragalot: then report back
01:59 AM gloops: oh yeah, these will stay for a while, until i get 2 smaller pulleys
01:59 AM gloops: yes i will
02:00 AM Wolf__: need this setup https://i.imgur.com/l7KoMTm.jpg lol
02:00 AM gloops: see, the problem with psus, the chinese ones go from 24-36v then 48-60v
02:01 AM Wolf__: they have 40V
02:01 AM gloops: i bought a 48-60v, but its minimum output is 54volts - red lights the drivers
02:01 AM archivist: slow the acceleration and top sped to stop stalling
02:01 AM fragalot: Wolf__: that is indeed a nice setup to diagnose!
02:01 AM gloops: Wolf the 36v gives 44volts
02:02 AM Wolf__: whats funny is you can see the voltage draw on the meters even tho its all ganged off one PSU lol
02:02 AM fragalot: Wolf__: where do you measure - on the drive, or on the psu?
02:02 AM Wolf__: at the drivers
02:02 AM fragalot: Excellent. :-)
02:03 AM fragalot: if there is a high current draw, you'll still see some variation
02:03 AM gloops: thats how to monitor your power supply heh
02:03 AM Wolf__: that way you can watch the reading dip lol
02:03 AM fragalot: gloops: when you measure the PSU voltage, make sure to do it on the drives.
02:03 AM fragalot: that will also show any voltage drop over the wiring
02:03 AM MrHindsight: anyone in the US need way or spindle oil?
02:03 AM gloops: coming from the driver > motor?
02:04 AM Wolf__: I have it wired pretty good but get to see 0.1-0.2v drop when its loaded
02:04 AM fragalot: gloops: input of the driver
02:04 AM gloops: ill just take readings all over anyway
02:04 AM gloops: its only 10 inch of wire from psu to driver
02:04 AM fragalot: Wolf__: sounds about right, but that's still under 3% which is what I typically take as acceptable.
02:05 AM fragalot: gloops: what size wire?
02:05 AM Wolf__: thats only a 4” run lol
02:05 AM Wolf__: https://i.imgur.com/iAeCFWH.jpg
02:05 AM gloops: 1.5mm
02:05 AM fragalot: that should be OK for that length
02:06 AM fragalot: Wolf__: I am disappointed the stepper wires are not twisted in pairs. :P
02:06 AM Wolf__: lol
02:06 AM fragalot: do the drives get warm when they're that close together?
02:06 AM fragalot: I'm not sure how close I can put mine together.. gut feeling says 20mm spacing
02:06 AM fragalot: the manual doesn't mention anything
02:06 AM Wolf__: no, the amp draw never gets over 1.5 on this setup
02:07 AM fragalot: oh right
02:08 AM archivist: alloy case takes heat away too, and drivers are switching so dont get that warm
02:08 AM fragalot: warm enough to need a heatsink
02:08 AM fragalot: with fan
02:09 AM Wolf__: https://i.imgur.com/v68lNrg.jpg
02:09 AM archivist: mine have never got that warm
02:09 AM fragalot: Wolf__: you must go deeper.
02:09 AM Wolf__: now the stepper motors on the other hand lol
02:10 AM archivist: people do jump when they touch my B axis motor :)
02:10 AM Wolf__: https://i.imgur.com/XRTwasV.jpg
02:10 AM fragalot: Wolf__: https://imgur.com/r/mildlyinteresting/zAdJzLP
02:11 AM Wolf__: eh lol
02:12 AM fragalot: Wolf__: how did the A9 project turn out?
02:13 AM Wolf__: a9?
02:13 AM fragalot: cutting A9
02:13 AM fragalot: wait. never mind.
02:13 AM fragalot: I was confusing you with Tom_L >.<
02:13 AM fragalot: I'm awake! Honest!
02:13 AM Wolf__: lol
02:18 AM gloops: an issue with using 2 steppers, while their combined strength may be well adequate, if they are not stepping exactly in sync, for an instant 1 motor will be pushing all the weight alone, if that motor misses it could set off the cascade of missed steps
02:19 AM Wolf__: get bigger https://i.imgur.com/rMK9yC1.jpg =p
02:19 AM fragalot: gloops: your frame is not rigid enough for that to happen
02:19 AM Wolf__: or even more https://i.imgur.com/r2krYgI.jpg
02:20 AM Wolf__: 821w 14.21Nm servo
02:20 AM Wolf__: might twist some stuff
02:21 AM fragalot: That's not a servo. That's a spindle. :D
02:21 AM gloops: i had a page with bigger open loops steppers, but cant find it now
02:22 AM MrHindsight: what to do with this? (has lead screws) https://imagebin.ca/v/3qALefb0ease
02:23 AM fragalot: looks like a toy
02:23 AM Wolf__: cnc pancake extruder
02:24 AM fragalot: are the ways cast aluminium?
02:24 AM MrHindsight: yes
02:24 AM fragalot: ew.
02:25 AM MrHindsight: yeah, pretty basic
02:25 AM fragalot: I wish more delivery services would give you an ETA...
02:25 AM fragalot: GLS gives you an approximate hour, which I think is fantastic.
02:25 AM MrHindsight: sometime this week
02:25 AM fragalot: but all the others just say "yeah some time between 6 and 22.. probably."
02:25 AM MrHindsight: we will be sure to leave a note that we missed you :)
02:26 AM fragalot: all I want to know is "is it safe for me to shower" lol
02:26 AM Wolf__: all I get is “by 8pm"
02:26 AM fragalot: MrHindsight: DPD is horrible for that
02:26 AM MrHindsight: sure, as soon as you're in it will be at the door
02:26 AM fragalot: they leave a note, stating you can pick it up the next day after 11am, in a random location nowhere near me.
02:26 AM fragalot: every time, it is a different location, and every time it's further away than the previous time
02:26 AM MrHindsight: sometimes I fool them and not shower and then they come the next day
02:27 AM fragalot: and this is a package I want here, because it does not fit in my car :D
02:27 AM fragalot: (electrical cabinet for the CNC)
02:27 AM MrHindsight: our Fedex comes in the am 4 days a week and then late pm one day a week but...
02:28 AM MrHindsight: you never know which day is am or pm
02:29 AM MrHindsight: I can almost set my clock by the UPS guys timing
02:29 AM MrHindsight: every day within a few minutes
02:29 AM fragalot: I have bad experiences with UPS
02:30 AM Wolf__: none of them are consistent here
02:30 AM fragalot: ordered my laptop from DELL, UPS guys missed me because I'm at work, leaves note, note states "you can change the delivery address here:"
02:30 AM MrHindsight: yeah depends on your area, either UPS or FEDEX is bad never both good
02:30 AM fragalot: so I change it to have it delivered to a pick-up point
02:30 AM MrHindsight: sometimes both bad
02:30 AM fragalot: sorry, change it to hav eit delivered at work
02:30 AM fragalot: they email me saying it's been dropped off at a pick up point
02:30 AM fragalot: I go to the pickup point "no it's not here yet, check back tmorrow"
02:30 AM fragalot: I get an email stating they're forwarding it to work
02:30 AM MrHindsight: I hate that
02:30 AM fragalot: get an email stating it's delivered at the pick up point
02:31 AM fragalot: go to the pickup point, "no not here"
02:31 AM MrHindsight: I once chased Fedex back and forth
02:31 AM fragalot: go home,.. wife's accepted it at our door.
02:31 AM fragalot: after that, get an email from UPS saying they'll send it back if I don't go pick it up
02:31 AM fragalot: lol
02:31 AM MrHindsight: yeah, go ahead a try
02:31 AM MrHindsight: a/and
02:32 AM MrHindsight: USPS is really good until they lose something
02:32 AM MrHindsight: then they really really suck
02:32 AM fragalot: they lost something for me
02:33 AM fragalot: which got dropped at customs without notifying me, until customs sent me an invoice for 6 months of storage
02:33 AM gloops: multimeter, V sign with ---, 1.08
02:33 AM MrHindsight: takes me 2-3 months to get my refund and insurance
02:33 AM gloops: whats that 10 volts??
02:33 AM fragalot: gloops: V= or V~ ?
02:33 AM Wolf__: I had a package almost lost by USPS, not their fault https://i.imgur.com/pSr8a99.jpg lol
02:33 AM gloops: not the one with the squiggly line
02:33 AM fragalot: ok
02:33 AM fragalot: that means 1 volt.
02:33 AM fragalot: which is.. not a lot.
02:34 AM MrHindsight: Parcel Farce in the UK is really awful
02:34 AM gloops: it went up to 1.8 when moving
02:34 AM fragalot: MrHindsight: I never got my refund, nor my insurance. they claimed delivered intact to customs, customs claimed delivered damaged.
02:34 AM fragalot: I gave up after a year or trying
02:34 AM MrHindsight: they would not deliver a package without a steet number even though the whole street was the factory
02:34 AM fragalot: gloops: something is wrong with the way you are measuring I think
02:34 AM gloops: ill have to set some code for it to run at full spped later i cant jog it manually and hold multimeter
02:35 AM gloops: fragalot yes i assume so
02:35 AM fragalot: gloops: because if you have a 44V power supply, you should get 44V...
02:35 AM gloops: ill leave it while later i havent got time today
02:35 AM fragalot: gloops: you ARE measuring the input , and not the motor, right?
02:35 AM fragalot: ok
02:36 AM MrHindsight: USPS damaged a 20 L pail of resin, they stored it on its side after they dropped it...
02:36 AM fragalot: MrHindsight: haha.
02:36 AM gloops: that was the input pins from the psu to the driver
02:36 AM fragalot: gloops: will need pictures when you start again.
02:36 AM MrHindsight: the picture from customs shows it in a sealed bag on its side with the arrows that mean UP sideways
02:38 AM fragalot: MrHindsight: shame they didn't ship the hardener in the same box then
02:39 AM fragalot: would have been fun if it leaked all over their stuff & then set up
02:39 AM MrHindsight: it was a photopolymer
02:39 AM fragalot: even better
03:03 AM MrHindsight: https://techxplore.com/news/2018-02-wood-strong-titanium-alloys-lighter.html
03:03 AM MrHindsight: will we see wooden tooling in the future?
03:04 AM fragalot: I don't think so
03:05 AM MrHindsight: https://www.nature.com/articles/nature25476
03:05 AM MrHindsight: https://media.springernature.com/m685/nature-assets/nature/journal/v554/n7691/images/nature25476-f1.jpg
03:06 AM fragalot: this is talking about structural strength, not hardness
03:06 AM MrHindsight: wooden tool holders :)
03:06 AM gloops: wood is stronger than steel in some applications
03:06 AM fragalot: haha
03:06 AM gloops: in a fire a steel beam bends and twists and fails
03:06 AM fragalot: I have to say though; with all of the recent advancements in materials, this is truly an amazing time to be alive
03:06 AM gloops: wood just goes black on the outside
03:07 AM MrHindsight: https://media.springernature.com/m685/nature-assets/nature/journal/v554/n7691/images/nature25476-f2.jpg
03:08 AM Wolf__: i’ll be impressed when battery energy density makes a giant increase
03:08 AM fragalot: Wolf__: it will soon.
03:08 AM fragalot: I was part of an R&D project that showed 80x increases in storage capacity and 200x in current ratings
03:09 AM fragalot: the electrodes are good, the nanocoatings are good, the only thing holding them back now is the electrolyte
03:09 AM Wolf__: cordless tools with corded performance running on a 26650 sized cell would be great lol
03:09 AM fragalot: give it another few years
03:10 AM MrHindsight: transparent wood
03:12 AM fragalot: MrHindsight: do you know if this epoxy would be alright to use as a bonding agent for epoxygranite? https://www.mrboat.nl/mrboat-epoxy/mr-boat-epoxy-30-kilo/
03:14 AM MrHindsight: Diglycidylether of Bisphenol-A type expoy resin
03:15 AM MrHindsight: bisphenol F-(epichlorhydrin) epoxy resin
03:15 AM fragalot: I know some of those words.
03:15 AM MrHindsight: Oxirane, mono[(C12-C14-alkyloxy)methyl] derivats
03:16 AM MrHindsight: http://cms.expotis.nl/_Included_Code/control_download_file.php?filepath=_Files_Products&filename=17-file_3-technisch-blad-epoxyhars.pdf&siteid=56
03:16 AM MrHindsight: NPEF-164X is a Bisphenol-A type epoxy resin Modified by Bisphenol-
03:16 AM MrHindsight: F type epoxy resin and then diluted with reactive diluent C12~C14
03:16 AM MrHindsight: Aliphatic Glycidyl ester,which has low viscosity to processing
03:16 AM MrHindsight: 700-1100 cPs
03:17 AM MrHindsight: so pretty low for an epoxy
03:17 AM MrHindsight: and the curing agent is a slow type
03:18 AM fragalot: I may just buy the 60kg offer for €535 if it will work
03:18 AM MrHindsight: good price
03:19 AM fragalot: so if I cast this thing, I'll have to mix it up in batches.. Can I continuously add more layers if I do each new layer within 20 minutes or so?
03:20 AM fragalot: or does it really have to go in in a continuous pour
03:20 AM MrHindsight: yeah, they will still crosslink to each other
03:20 AM fragalot: Good. :-)
03:21 AM MrHindsight: Gel time @23°C: 30 - 35 minutes
03:21 AM MrHindsight: and it's still crosslinking well after that time
03:21 AM fragalot: Sweet.
03:22 AM fragalot: moving on to finding a source for the filler materials
03:22 AM MrHindsight: you just shouldn't try to mix it or pour after that time
03:22 AM fragalot: alright
03:22 AM MrHindsight: the viscosity will be so high that you'll just have voids if stirred
03:23 AM MrHindsight: gel time will be longer if it's cooler
03:23 AM MrHindsight: use chilled aggregate
03:23 AM fragalot: heh... found a place that sells granite in 2-8mm and 8-16mm formats, but I need to buy 1100kg minimum of each >.<
03:26 AM MrHindsight: what price for 1100kG?
03:26 AM fragalot: $99
03:26 AM fragalot: €, not $
03:26 AM MrHindsight: yeah , abut the same here
03:26 AM fragalot: I just have nowhere to put the leftovers
03:27 AM MrHindsight: Craigslist
03:27 AM MrHindsight: free granite gravel, BYOT
03:28 AM MrHindsight: or loose some on the way home
03:28 AM fragalot: haha
03:28 AM fragalot: that €99 is delivered in a bigbag
03:28 AM MrHindsight: magic rocks $10 / Kg
03:29 AM fragalot: xD
03:29 AM MrHindsight: take 1 Kg with you to work every day for a year
03:29 AM fragalot: I wonder if basalt is also ok?
03:30 AM MrHindsight: too many voids
03:30 AM fragalot: k
03:30 AM MrHindsight: granite is very dense
03:30 AM fragalot: shame, because I can get that literally around the corner
03:31 AM MrHindsight: https://pubs.acs.org/doi/10.1021/acs.biomac.6b00145
03:31 AM fragalot: MrHindsight: basalt is actually denser
03:31 AM MrHindsight: tried to find an open version of the paper
03:31 AM MrHindsight: maybe the type you found
03:32 AM MrHindsight: where is Mr Rock?
03:35 AM fragalot: MrHindsight: granite = 2700kg/m³, basalt = 3000kg/m³
03:35 AM MrHindsight: give it a try
03:36 AM fragalot: basalt seems to have a Mohs hardness of 8, whilst granite is only a 6-7

03:36 AM MrHindsight: i pictured this type
03:36 AM fragalot: oh no, MrHindsight: http://www.natuursteenbestellen.be/basalt-split-minibag-500kg
03:36 AM fragalot: there aren't any voids in this gravel; and it's super popular and easy to get here
03:37 AM MrHindsight: does it cleave poorly?
03:38 AM fragalot: I think basalt tends to fracture
03:39 AM fragalot: http://basalt.today/images/Mechanical-and-morphological-properties-of-basalt-filled-polymer-matrix-composites.pdf
03:41 AM MrHindsight: granite more better
03:42 AM fragalot: k, just need to find granite in reasonable QTY's then :)
03:42 AM fragalot: smallest I can get in small bags seems to be 8mm
03:43 AM * fragalot wonders how much rock crushers cost xD
03:44 AM MrHindsight: hasta
03:52 AM fragalot: ffs, if I look for crusher all I get are online weed accessory shops
03:58 AM fragalot: delivery truck!
03:59 AM fragalot: aww partial delivery only :(
04:00 AM * Loetmichel just had to measure the inner pin of a hollow dc plug... so i raped a digital caliper. Good thing that they cost only 10 eur ... if i had done that with the 250DM mitutoyo in my first apprenticeship my master would have hit me in the face repeatedly... and with good reason... -> http://www.cyrom.org/palbum/main.php?g2_itemId=16971&g2_imageViewsIndex=1
04:01 AM fragalot: that's what the cheapies are good for
04:02 AM fragalot: they're right up there with files in terms of "modify if you need to"
04:10 AM pink_vampire: lol
04:11 AM pink_vampire: the smell is killing me here
04:12 AM pink_vampire: i'm starving and there is pizza in the oven
04:13 AM fragalot: xD
04:13 AM fragalot: Well. good news is that my electrical panel arrived. bad news is, I'm still missing 60% of the stuff I want to put in there
04:15 AM pink_vampire: pics pics pics pics pics pics pics pics pics pics pics pics pics pics pics
04:15 AM fragalot: k, gimme a second
04:17 AM pink_vampire: ok :)
04:20 AM pink_vampire: Loetmichel: you need a cmm
04:20 AM fragalot: pink_vampire: uploading...
04:21 AM pink_vampire: i have the pizza now.. i'm relaxed
04:22 AM fragalot: laptop shat the bed apparently and corrupted the file >.>
04:22 AM pink_vampire: O_O
04:22 AM fragalot: I'll have them converted again & will upload shortly.
04:23 AM pink_vampire: ok
04:23 AM fragalot: Enjoy your pizza meanwhile
04:24 AM pink_vampire: thanks :)
04:26 AM evilren: urmom is pizza.
04:27 AM Deejay: moin
04:27 AM pink_vampire: moin
04:29 AM Deejay: haha, hey pink :)
04:30 AM fragalot: exporting images...
04:30 AM pink_vampire: ...
04:31 AM fragalot: https://imgur.com/a/6q6OU - uploading here..
04:31 AM fragalot: done
04:31 AM fragalot: (hint: right-click image, view image)
04:32 AM Wolf__: mmm box
04:32 AM pink_vampire: look very nice!
04:32 AM fragalot: yeah i use these panels a lot; really high quality
04:33 AM pink_vampire: i don't like heatsinks in the panel
04:33 AM fragalot: typically I use the stainless version, but those are way out of my budget range if it's for me. lol
04:33 AM fragalot: pink_vampire: gotta put them somewhere.. The panel itself will have a fan in it to keep everything cool.
04:33 AM pink_vampire: how much it cost?
04:34 AM fragalot: but this panel should have room for 3 power supplies, 3 drivers, 3 big capacitors + protection TVS diodes, and the VFD, whilst keeping everything nicely shielded from eachother.
04:35 AM fragalot: pink_vampire: the panel itself was €190
04:35 AM pink_vampire: not bad
04:36 AM pink_vampire: https://i.imgur.com/4eebqfD.png
04:37 AM pink_vampire: this is how i did the drivers https://i.imgur.com/ZsfPTZI.png
04:37 AM fragalot: Creative
04:38 AM Wolf__: looks like a gun locker
04:38 AM pink_vampire: it is
04:39 AM pink_vampire: i like the frame around the door, it make very nice room for the pilot devices
04:40 AM fragalot: I just had a look and I don't think I can easily do that in my cabinet without some trickery
04:40 AM Wolf__: locker that size seems overkill
04:40 AM Wolf__: what do you use the rest of the space in it for?
04:41 AM pink_vampire: lets see the inside
04:41 AM pink_vampire: https://i.imgur.com/bHwwIf5.png
04:43 AM Wolf__: so its 80% empty?
04:45 AM fragalot: room for expansion
04:45 AM pink_vampire: i left some space for upgrades and changes. and everything is mount on 80/20 rails
04:46 AM Wolf__: I think that thing is bigger then the cabinet on my friends Hass VMC
04:46 AM pink_vampire: for 179$..
04:46 AM Wolf__: and you could fit 3 of those cabinets in the VMC lol
04:46 AM XXCoder: hey all
04:47 AM XXCoder: funny thing happened today
04:47 AM XXCoder: i got my new phone, and old one SIM finally died for good
04:47 AM XXCoder: on same day.
04:48 AM pink_vampire: Wolf__: i looked at it as floor space, narrow and tall vs normal electrical cabinet.
04:49 AM Wolf__: normal cnc cabinet would be about 1/8th that size
04:49 AM pink_vampire: i know
04:49 AM XXCoder: I guess I timed it perfectly.
04:49 AM fragalot: I just laid out all the parts on my table & measured what I needed, then picked the size that I know Rittal has
04:50 AM fragalot: never thought about doing what pink_vampire does & mount the heatsinks outside
04:50 AM fragalot: but I think I can do that if I poke all 3 out the left side if I make a little mounting bracket
04:50 AM Wolf__: I couldn’t fit all that in one of my gun safes
04:52 AM pink_vampire: Wolf__: it's also about making it comfortable to work inside
04:52 AM pink_vampire: the original idea was to use the G0704 cabinet
04:53 AM Wolf__: https://i.imgur.com/iAeCFWH.jpg worked for my X1, not sure what I’ll do for the X2
04:54 AM Wolf__: if I was doing up a cabinet like fragalot is using, I would put everything on a sub plate so you dont need to work inside the box
04:55 AM pink_vampire: wiress...
04:55 AM pink_vampire: on my machine there is ZERO connectors.
04:56 AM XXCoder: Wolf__: I remember that pic
04:56 AM XXCoder: still yet to design mine!
04:56 AM fragalot: Wolf__: mine's on a sub plate, but nobody takes those things out, too annoying to have to disconnect everything
04:57 AM fragalot: the reason for the sub plate in the real world is to provide a good surface for grounding, and allows you to mount things without poking holes in the outside shell of the cabinet
04:57 AM pink_vampire: the best thing in my cabinet is light
04:57 AM Wolf__: yeah, fun part is figuring out how to limit the amount of points to pull the thing out =]
04:57 AM pink_vampire: make the work much much easier
04:57 AM fragalot: pink_vampire's solution is quite acceptable in my opinion
04:58 AM fragalot: I prefer cabinets to be too large than cabinets that are just that little bit too small
04:59 AM Wolf__: thats what? 30”x24”x60” cabinet?
04:59 AM pink_vampire: noo
04:59 AM pink_vampire: let me see
04:59 AM XXCoder: mine would be 550x300x200 mm
04:59 AM XXCoder: but maybe I will use old computer case as cabinet>?
04:59 AM pink_vampire: 21x10x54
05:00 AM fragalot: mine's 760x699x210mm
05:00 AM fragalot: 600*
05:00 AM fragalot: and will be quite full by the time I'm done.
05:01 AM pink_vampire: 300*600*1370
05:02 AM pink_vampire: mine in a bit deeper and taller,it take less floor space, and you controls are much higher.
05:03 AM pink_vampire: your*
05:05 AM fragalot: i'm not sure yet if i'm going to put my cabinet above or under the cnc
05:05 AM archivist: under is hard to maintain /fault find
05:06 AM pink_vampire: is that for a mill?
05:08 AM fragalot: pink_vampire: yes. a custom epoxy-granite build
05:09 AM XXCoder: someone actually did that. cool
05:10 AM pink_vampire: i wish i have the resources for that
05:12 AM fragalot: this is taking time.
05:12 AM fragalot: pink_vampire: I don't really have them either, lol
05:12 AM fragalot: just more patience than I thought I had
05:12 AM Wolf__: I fear at some point I’ll just end up getting a VMC and doing a retrofit
05:13 AM fragalot: I don't have the room for a VMC
05:13 AM fragalot: i'm limited to bringing in things that I can personally lift, and nono wider than 800mm
05:14 AM pink_vampire: you just need the biggest and heaviest machine that you can fit in your home.
05:14 AM XXCoder: *and can still live in said home ;)
05:14 AM fragalot: pink_vampire: or something that I can get in there in pieces :-)
05:15 AM fragalot: which is what I did with the RF45
05:15 AM Wolf__: I plan to replace my current shop w/ a 60’x40’ (18mx12m)
05:15 AM fragalot: that's a nice size
05:15 AM fragalot: mine's 6x3
05:15 AM pink_vampire: mine is 0x0
05:16 AM Wolf__: and I already have 2 forklifts 8k lbs and 5k
05:17 AM fragalot: I have 2 strong arms, and a bad back :P
05:18 AM fragalot: getting the 175kg lathe up the attic was bad enough
05:18 AM fragalot: getting it down again to put in the shed was another matter
05:18 AM pink_vampire: up the attic!! O_o !
05:20 AM fragalot: had to start somewhere!
05:20 AM XXCoder: yeah have to start breaking back somewhere
05:20 AM archivist: I had my first lathe in the loft, complaints of noise after midnight :)
05:20 AM fragalot: ^
05:20 AM fragalot: now the attic is my electronics lab
05:20 AM archivist: I have that in the lounge
05:21 AM pink_vampire: what is the size of the inserts for the HF holders?
05:22 AM pink_vampire: those ones https://www.harborfreight.com/5-piece-indexable-carbide-tool-set-39931.html
05:23 AM XXCoder: shank is 1/4
05:23 AM XXCoder: in
05:23 AM pink_vampire: is it tnmg?
05:24 AM fragalot: just has to start with T
05:25 AM fragalot: as for the size.. maybe 11?
05:25 AM fragalot: (that is a wild guess)
05:25 AM pink_vampire: i need something small for my mill
05:29 AM fragalot: I'm using CCMT060204 on my fly cutter
05:30 AM fragalot: and on my lathe, big holder but small (cheap) insert
05:30 AM archivist: I use whatever is to hand, make the tooling to fit
05:30 AM fragalot: I mainly use the smaller inserts because I can't take deep cuts anyway, so big carbide is a big waste :P
05:31 AM pink_vampire: i don't like the tools in the vise
05:31 AM fragalot: the broken ones get brazed & ground
05:31 AM pink_vampire: if i push the material the tool is moving
05:31 AM fragalot: pink_vampire: sounds like you need a better vise?
05:32 AM pink_vampire: no
05:32 AM pink_vampire: the way you apply force make it slip
05:32 AM fragalot: only if it's not clamped hard enough
05:32 AM fragalot: but yes.
05:33 AM fragalot: if cutting force is an issue, you may want to either grind your own carbide, or go for HSS
05:33 AM pink_vampire: if you mill you push the material against the parallels, here there is noting to support the tool, so it slip
05:33 AM archivist: you are not holing properly
05:33 AM fragalot: pink_vampire: on old shapers they used to have the vise perpendicular to the cutter motion
05:33 AM pink_vampire: i will show you the "setup"
05:34 AM archivist: holding
05:34 AM pink_vampire: maybe I'm soo weak to close the vise all the way..
05:34 AM fragalot: pink_vampire: or the vise is racking?
05:34 AM archivist: I have the base of the lathe tool on the rotary table face when turning in the mill
05:36 AM pink_vampire: the tool
05:37 AM pink_vampire: https://i.imgur.com/8S15rD4.png
05:37 AM pink_vampire: this is how I "lathe" on the mill
05:38 AM pink_vampire: the part that I need is like the one on the right, the part on the collet is the fail that happen if the tool is slip in the vise
05:38 AM archivist: you need to put another tool other side of vice to stop the jaw rotating plus packing under
05:40 AM pink_vampire: I think to make like a gang plate, with several lathe tools
05:40 AM fragalot: pink_vampire: That should work fine, but you must put another tool on the left side of the vise to keep it parallel
05:40 AM fragalot: especially in brass there should be no excuse for that bit to move
05:40 AM pink_vampire: i have only one tool..
05:41 AM fragalot: pink_vampire: do you have something of equal thickness?
05:41 AM pink_vampire: it is from the grizzly fly cutter
05:41 AM pink_vampire: i can cut something..
05:41 AM archivist: make a packer
05:41 AM pink_vampire: http://www.hhrobertsmachinery.com/lathes/Chin-Hung/cl10sub.jpg
05:42 AM pink_vampire: that look like a nice setup
05:43 AM fragalot: if your parts are small enough
05:43 AM pink_vampire: stuff that fit normal r8 colltes
05:44 AM pink_vampire: https://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=33904&portrelay=1
05:44 AM pink_vampire: 95$
05:44 AM pink_vampire: wow
05:45 AM fragalot: I use these on my lathe. https://www.rdgtools.co.uk/acatalog/QUICK-CHANGE-TOOLPOST-SET-FOR-MYFORD-LATHE-WITH-PARTING---VEE-HOLDER---MYFQUICK.html#SID=453
05:45 AM fragalot: well, the larger version
05:45 AM fragalot: pink_vampire: you could look at the chinese quick-change toolpost holders
05:46 AM pink_vampire: i don't need changing
05:46 AM fragalot: no, but you can modify the holders
05:46 AM pink_vampire: i have the whole x axis to put tools
05:46 AM pink_vampire: i just need the tools
05:47 AM pink_vampire: and then make slots in metal bar and mount all the tools
05:47 AM pink_vampire: https://sherline.com/Wordpress/wp-content/uploads/2016/12/5930_pic3.jpg
05:48 AM pink_vampire: what type of holder is that?
05:48 AM fragalot: that's literally a block of aluminium with holes in it
05:48 AM XXCoder: pink you got a lathe now?
05:48 AM fragalot: :D
05:48 AM pink_vampire: XXCoder: https://i.imgur.com/8S15rD4.png
05:48 AM XXCoder: ahh that "lathe"
05:48 AM pink_vampire: yeah..
05:49 AM XXCoder: I see you ran linuxcnc rook
05:49 AM pink_vampire: i even did post processor for my "lathe"
05:52 AM pink_vampire: I love marketing jokes
05:52 AM pink_vampire: https://i.imgur.com/EO1Mxpw.png
05:53 AM fragalot: hehe
05:53 AM XXCoder: its industual. just like my lathe. ;)
05:54 AM pink_vampire: LOLL
05:54 AM pink_vampire: my lathe is more " industual"
05:54 AM fragalot: I have to say that I really really hate the use of the words "industrial" and "professional" on tools these days
05:55 AM fragalot: screwdrivers made of cheese are not "professioanl"
05:55 AM pink_vampire: "made of cheese" LOLLLLL
05:56 AM pink_vampire: actually the free screwdrivers set from HF is much better then the one I got from lowes
05:57 AM fragalot: best sets I've got are from Wera or Wiha.. I forgot.
05:57 AM fragalot: both are good.
05:58 AM fragalot: and for pliers I just always buy them from knipex and don't even bother looking at other brands anymore
05:59 AM pink_vampire: https://i.imgur.com/PJJhr3m.png
06:00 AM pink_vampire: the ones with the black handles was the free from HF and the red oned came with the G0704.
06:01 AM pink_vampire: I don't know why but those are the ones I'm using the most
06:02 AM pink_vampire: i need new heads for the setup hammer
06:05 AM fragalot: pink_vampire: https://imgur.com/a/4hvOk <- this is my man-cave. (still uploading, pictures will add themselves every few minutes)
06:07 AM pink_vampire: SUPER workshop!! I love how everything is organized! very refreshing on this channel!!
06:07 AM * archivist steals the tool and cutter grinder
06:07 AM fragalot: ~https://imgur.com/a/mmYRQ - second half.
06:08 AM jthornton: it's already stolen lol
06:08 AM fragalot: upload complete. :)
06:08 AM jthornton: what is the bar on top of the press for?
06:08 AM fragalot: jthornton: longer pump handle
06:09 AM fragalot: I usually only use the short one unless I need more than ~8 ton or so
06:09 AM jthornton: I need to make a short one for my press
06:09 AM fragalot: it's just a piece of galvanized pipe turned down to fit
06:09 AM jthornton: do you have a front on shot of the press?
06:10 AM jthornton: aye
06:10 AM fragalot: jthornton: yeah, second album
06:11 AM pink_vampire: I love the welding cart
06:11 AM fragalot: :)
06:11 AM fragalot: mig, tig, stick & plasma on that little cart
06:12 AM pink_vampire: the press is CRAZY
06:12 AM pink_vampire: wow
06:12 AM Tom_L: 21F & clear
06:12 AM jthornton: I like how you can move the cylinder with a jack screw
06:12 AM fragalot: yeah, that's an INDUSTRIAL model, not one of the chintsy chinese ones you get for €50
06:12 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_1.jpg
06:12 AM fragalot: jthornton: the spindle itself is also a screw press
06:12 AM jthornton: 21°F Fog/Mist
06:13 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A9_2.jpg
06:13 AM jthornton: the orange wheel?
06:13 AM fragalot: yeah
06:13 AM jthornton: neat
06:13 AM pink_vampire: do you have a wife?
06:13 AM XXCoder: or husband?
06:13 AM fragalot: pink_vampire: yes. I think she is starting to understand that she can't stop me. :P
06:14 AM * jthornton sees and egg in the nest box...
06:14 AM fragalot: all I want is for her to sell my tools for what they're worth when I die, and not for what I said I paid for them
06:14 AM pink_vampire: LOLLLLL
06:14 AM XXCoder: :)
06:15 AM XXCoder: I'll be very sure to be there if you dies
06:15 AM XXCoder: buy $10 each everything but smnall stuff
06:15 AM pink_vampire: i need a work shop!
06:15 AM fragalot: I need a bigger workshop >.>
06:15 AM XXCoder: "oh cnc mill is cheap nowdays I'm willing t pay $100"
06:15 AM fragalot: XXCoder: I'll take the $100 if you want that small one
06:15 AM fragalot: pick-up only
06:15 AM XXCoder: lol
06:16 AM XXCoder: sure! you come here and pick up the $100.
06:16 AM XXCoder: drop off the mill
06:16 AM jthornton: Tom_L: some kind of adjustable holder?
06:17 AM fragalot: I think it's a can opener
06:22 AM pink_vampire: fragalot: what kind of stuff are you making?
06:22 AM fragalot: odd jobs, mostly fixing things
06:23 AM fragalot: i'm in it for the hobby, not professionally
06:23 AM jthornton: looks like the RPi Zero with camera will run 44 hours on a 10,000 mAh Anker USB battery
06:24 AM fragalot: jthornton: you should be able to get more if you can get it to go to low power mode when not actively needed?
06:24 AM pink_vampire: fragalot: same here :)
06:24 AM pink_vampire: you are in a good company :)
06:25 AM jthornton: I've not found a way to make it go to low power mode
06:25 AM fragalot: pink_vampire: unlike you, I have not yet found a niche of products I can sell, like styrofoam tits...
06:25 AM jthornton: hmm I wonder if I slow down the processor
06:25 AM fragalot: Hmph, seems RPI's don't have ACPI
06:26 AM fragalot: jthornton: perhaps you sould forego the rPI and just hook up a cellphone? :P
06:26 AM pink_vampire: i was NEVER sold!
06:27 AM fragalot: pink_vampire: oh I assumed you sold those >.> my bad
06:28 AM jthornton: hmmm cellphone?
06:28 AM fragalot: jthornton: it's already a low power device that has a camera & battery
06:31 AM pink_vampire: maybe the metal version..
06:31 AM pink_vampire: https://i.imgur.com/cbGNhB6.png
06:32 AM pink_vampire: how much do you think is a good price for my tits?
06:33 AM fragalot: well, it's lacking an areola, so.. $2,50?
06:33 AM XXCoder: trying to price stuff ugh
06:33 AM fragalot: XXCoder: that's why i'm in this as a hobby :P
06:33 AM fragalot: I'll make you your part if you'll help me out when I need you.
06:34 AM XXCoder: right now cnc stuff is my expensive pointless thing to do lol
06:34 AM fragalot: Exactly. :D
06:38 AM pink_vampire: i need 0.05" ball endmill and 60K NSK spindel
06:44 AM pink_vampire: so nice to have a "lathe"
06:47 AM XXCoder: I wonder if lathe is makable with mill and mill "lathe"
06:48 AM pink_vampire: i never turn long stock
06:48 AM pink_vampire: so it is more like a swiss without bar feeder
06:50 AM XXCoder: lol ok
06:51 AM pink_vampire: swiss is basically money printing machine
06:59 AM fragalot: XXCoder: Yes, it is possible.
07:05 AM pink_vampire: DONE!!!!!!!!!!!!!!!!!!!
07:06 AM XXCoder: what is done?
07:06 AM pink_vampire: tool setter
07:08 AM XXCoder: nice!!
07:09 AM XXCoder: whats you use as sensor? forgot. laser?
07:09 AM pink_vampire: kinematic
07:11 AM archivist: swiss does not make money till you are in the thousands of parts
07:11 AM XXCoder: pink it detects some mechimism change position?
07:11 AM gregcnc: making money with any machine is having the right jobs for it and the people running it
07:15 AM archivist: I want to linuxcnc my swiss machine one day
07:16 AM pink_vampire: https://i.imgur.com/d6E1pkb.jpg
07:18 AM archivist: that used to be shiny!
07:18 AM pink_vampire: archivist: what was shiny?
07:19 AM archivist: before it was painted :)
07:19 AM pink_vampire: yes..
07:19 AM pink_vampire: I love the paint!
07:20 AM XXCoder: damn
07:21 AM XXCoder: damn you pink_vampire
07:21 AM XXCoder: I wanna try powder coating now
07:21 AM * XXCoder shakes fist
07:21 AM pink_vampire: it is sooo easy
07:21 AM fragalot: I can't find good kits to do it here
07:21 AM fragalot: plent of cheap ones on US sites
07:21 AM XXCoder: she used harbor freight tool if I recall right. then baked it in oven
07:21 AM pink_vampire: we can send you one...
07:21 AM fragalot: HF doesn't exist around these parts.
07:22 AM XXCoder: too bad
07:22 AM fragalot: pink_vampire: yea but I don't want to have to a) pay import duties b) get a 110V transformer
07:23 AM XXCoder: its lot easier to go down than up
07:23 AM pink_vampire: yeah
07:23 AM fragalot: XXCoder: it's the same amount of effort, actually
07:23 AM archivist: fragalot, nearer you than me https://www.ebay.co.uk/itm/Portable-Electrostatic-Powder-Coating-System-PC03-5-240V-AC-50Hz-16AWG-Spray-Gun/112443601558
07:24 AM fragalot: I currently only have 3phase 240V, and have a 5kW transformer to go to 3x400V
07:24 AM XXCoder: if I recall its easy to just divide volt
07:24 AM pink_vampire: archivist: this is look like identical to mine
07:24 AM fragalot: XXCoder: on DC for signals, yes.
07:24 AM archivist: it probably is the same thing
07:24 AM XXCoder: hm ok
07:24 AM fragalot: anyway all I'd need is a transformer, but meh.
07:25 AM fragalot: archivist: That looks like a toy though? would that actually work?
07:25 AM pink_vampire: fragalot: the one that archivist found look nice
07:25 AM archivist: that what she is using
07:25 AM fragalot: Hmm....
07:25 AM pink_vampire: https://www.harborfreight.com/10-30-psi-powder-coating-system-94244.html
07:25 AM * fragalot makes an offer of £ 80
07:25 AM XXCoder: honestly all you need is to coat clean part, then bake?
07:25 AM pink_vampire: this is the one I have
07:26 AM XXCoder: pink does that include compressor of its pown or do I supply pressured air
07:26 AM * fragalot makes an offer of £ 60
07:26 AM fragalot: xD
07:26 AM archivist: cheapskate :)
07:26 AM fragalot: looks like it needs air.
07:26 AM XXCoder: yeah
07:26 AM pink_vampire: sandblast > blow all the dust with air > powder coat > put in the oven for 15 min on 400F
07:26 AM fragalot: archivist: hey, it's £30 postage for that thing, and in the US it's only $80
07:27 AM fragalot: i'm not a cheapskate, they're just trying to rip us off :P
07:27 AM pink_vampire: it is but only 10-15 psi
07:27 AM archivist: fragalot, the gov need its share!
07:27 AM XXCoder: im still not sure how that thing works pink
07:27 AM fragalot: No they don't >.>
07:27 AM XXCoder: does it detect position change as tool hits it
07:27 AM pink_vampire: super simple
07:28 AM pink_vampire: the paint it positively charged and the part is negatively charged so the paint stick to the part.
07:28 AM pink_vampire: like laser printer
07:28 AM fragalot: pink_vampire: I think he means the tool detection thingymajigger
07:28 AM XXCoder: no no the TLO sensor
07:28 AM XXCoder: powder coat is pretty simple
07:29 AM pink_vampire: the tool setter, is just a kinematic switch in a nice box.
07:29 AM pink_vampire: and calibration platform
07:31 AM pink_vampire: there is cylinder and a sphere on a bar that connect to the switch, so you can use it as a reference point on your machine
07:32 AM pink_vampire: for flat / uneven objects the you use the sphere, and for round objects you use the flat on the cylinder
07:34 AM pink_vampire: XXCoder: ^
07:37 AM gregcnc: the base is adjustable to make the cylinder parallel to the table?
07:37 AM pink_vampire: correct
07:37 AM XXCoder: pretty amazing
07:38 AM XXCoder: how repeatable is it?
07:38 AM pink_vampire: i have no idea
07:38 AM fragalot: lol
07:38 AM pink_vampire: but it is based on the probe i did, and the probe is better then the machine. so...
07:39 AM pink_vampire: i have no idea because it is not connected yet
07:40 AM XXCoder: well can always make gcode to make tool probe its length repeatively
07:40 AM fragalot: seems locally sourced powdercoat devices are €200 for the "ultra low-end"
07:40 AM XXCoder: then do some math
07:41 AM pink_vampire: fragalot: where are you located?
07:41 AM fragalot: pink_vampire: are you asking so you can steal stuff from my shed? >.>
07:42 AM pink_vampire: I never steal anything, you will give it to me anyway because of my smile.
07:43 AM * fragalot is suspicious
07:43 AM XXCoder: so many jokes.
07:43 AM pink_vampire: I'm too cute to resist
07:43 AM fragalot: fine >.< belgium.
07:43 AM pink_vampire: you see.
07:43 AM * fragalot runs to double check the deadbolts
07:45 AM gregcnc: pink used to post pictures of her manicure
07:45 AM XXCoder: 3 inch nails
07:45 AM pink_vampire: now it is looks poor
07:45 AM XXCoder: I dont know how she machines with it
07:45 AM fragalot: I quite like nine inch nails, actually.
07:45 AM XXCoder: or do anything else
07:45 AM pink_vampire: old days...
07:46 AM pink_vampire: XXCoder: you mean to that picture https://i.imgur.com/M4usYSW.png
07:46 AM XXCoder: yep
07:47 AM pink_vampire: now i have too many scars on my hands :(
07:48 AM XXCoder: had bunch before working as machinist, now has more
07:48 AM XXCoder: as long as I have all fingers
07:48 AM XXCoder: i dont want to "lisp
07:48 AM fragalot: y'know what
07:48 AM fragalot: i'm going to make my own powdercoat gun
07:48 AM fragalot: with blackjack
07:49 AM fragalot: and hookers.
07:49 AM pink_vampire: o_O O_O O_o
07:49 AM fragalot: pink_vampire: https://www.youtube.com/watch?v=e35AQK014tI
07:50 AM pink_vampire: WTF did I just watch
07:51 AM gregcnc: dang.... Ø1mm max stock size lathe http://cmj.citizen.co.jp/english/product/cincom/cincom_r01_04.html
07:52 AM pink_vampire: Weight 1,050kg
07:52 AM fragalot: I can't carry that.
07:52 AM pink_vampire: there is no bar feed, it's a wire feed
07:54 AM gregcnc: i doubt it
07:54 AM fragalot: that would be amazing
07:54 AM fragalot: spinning up a wire that is still coiled up
07:55 AM pink_vampire: i put it that way.
07:56 AM pink_vampire: 1mm is too small to be a bar
07:56 AM archivist: it is a bar in terms of how it is used
07:57 AM archivist: watch parts are in that size range
07:58 AM XXCoder: max 1 to 4 mm dia?
07:58 AM XXCoder: insane
07:59 AM gregcnc: programs to .1micron
07:59 AM syyl: having the controller going down to 0.1micron is not so uncommon
07:59 AM gregcnc: yeha not any more
08:00 AM XXCoder: later
08:00 AM pink_vampire: my machine feel like pile of junk right now
08:00 AM fragalot: pink_vampire: at least yours is an assembled pile of junk
08:00 AM fragalot: mine is literally a pile of junk.
08:00 AM pink_vampire: LOL
08:00 AM gregcnc: it also didn't cost 200kUSD
08:01 AM pink_vampire: fragalot: after saying something like that you need to supply a pic.
08:01 AM fragalot: pink_vampire: I already did
08:01 AM pink_vampire: i saw nice blue mill
08:01 AM fragalot: you saw the cabinet, and my little trial electrical setup
08:02 AM fragalot: and the rails, leadscrews etc were in the shed on the workbench
08:02 AM gregcnc: https://www.instagram.com/p/Be7FZa2g4fT/?tagged=instamachinist
08:02 AM fragalot: motors & spindle are in a box still
08:02 AM archivist: and the table in the middle had 2 rails and a screw
08:02 AM fragalot: gregcnc: I doubt that would stop pink_vampire
08:02 AM gregcnc: she would steal those
08:02 AM pink_vampire: GONE!
08:03 AM fragalot: or is the implication that people don't steel absolute shite?
08:03 AM fragalot: steal$
08:03 AM fragalot: *
08:04 AM pink_vampire: i need to take a looooong shower, do my nails, and think about the next part.
08:04 AM gregcnc: pink is a bigger deterent than quality, people actually pay for harbor freight tools, but if everything in the store was pink it would have closed yesterday
08:05 AM pink_vampire: gregcnc: some of the stuff in HF actually very good.
08:05 AM gregcnc: the kind of parts you make on that citizen above https://www.instagram.com/p/Be3iniGh-Tr/
08:05 AM * jym paints some tools pink, keeps them from getting borrowed/stolen =)
08:05 AM gregcnc: pink i wouldn't know
08:06 AM jym: hot pink too
08:07 AM fragalot: gregcnc: cute
08:07 AM fragalot: I would lose so many of those in the chip pan
08:07 AM pink_vampire: jym: ihard to believe
08:07 AM pink_vampire: i'm*
08:07 AM jym: pink_vampire: ?
08:07 AM gregcnc: you have to be creative with parts catching otherwise you're throwing away money
08:08 AM pink_vampire: 09:04:18] jym paints some tools pink, keeps them from getting borrowed/stolen =)
08:08 AM jym: pink_vampire: It works
08:08 AM jym: pink_vampire: it also makes things easier to find/spot too
08:09 AM pink_vampire: pink is just green in inverted phase.
08:09 AM jym: like a box knife
08:27 AM pink_vampire: Tom_L: why did you make the can holder?
08:34 AM fragalot: pink_vampire: he's plannig to become a professional canner.
08:39 AM pink_vampire: what do you mean??
11:42 AM IchGucksLive: hi
11:42 AM fragalot: Hey.
11:59 AM gloops: ive only just realised Acorn linear motion is a few miles away from me
12:01 PM gloops: need to find someone who works there
12:01 PM IchGucksLive: gloops: are you unsadisfied as you search for errors
12:02 PM IchGucksLive: i now build a real big quantety of routers gantrys and non did fail
12:02 PM IchGucksLive: gloops: what has been your testconditions
12:03 PM gloops: Ichs, to quote Winston Churchill on the American landings, ' i thought we'd thrown a wildcat onto the beaches of Sicily, instead we got a beached whale!'
12:03 PM IchGucksLive: did you use a compiled 2.8
12:03 PM IchGucksLive: why if it fails not going with 2.7.12
12:03 PM gloops: Ichs no the 2.8 off the repository, the signals seem fine, the gantry isnt as fast as i was hoping for thats all
12:04 PM gregcnc: oh yeah, did you measure any voltages or currents?
12:04 PM IchGucksLive: Test on G0 or Max Feed
12:04 PM IchGucksLive: you may also be fooled by the Drivers
12:04 PM IchGucksLive: did you open one
12:05 PM gloops: not had chance to do any proper tests yet, will be the weekend, im fairly convinced 2000mm/min is the limit for these motors, but i will do some testing
12:05 PM IchGucksLive: if there is no 432 in
12:05 PM gloops: the Y is fine, same driver same motor, 5000mm
12:06 PM IchGucksLive: but alone tested
12:06 PM gloops: linuxcnc seems to be synchronising the motos very well, theres no step loss at normal speeds
12:06 PM gregcnc: he has 9.8A powersupply for 4 steppers set to 3.75A
12:07 PM gloops: what would you reccomend gregcnc?
12:07 PM gregcnc: does it get worse if you move 2 or 3 axes?
12:07 PM gloops: not tried that
12:07 PM gregcnc: i don't do steppers, so i would have to do some math
12:08 PM gregcnc: ichs likes steppers
12:08 PM gloops: well i have a working gantry, its just slower than i hoped for, the logical solution is to get some 8nm closed loop steppers, which i will - but not till ive used this machine for a while
12:09 PM gloops: i can cut at 80ipm, thats fine for now
12:09 PM gregcnc: if you power supply voltage is dropping under load the stepper current drops and torque drops
12:09 PM gloops: it is a success! linuxcnc can do the gantry, i managed to make one that works
12:09 PM IchGucksLive: gloops: what if you invest for a 400W 24V
12:10 PM IchGucksLive: same size
12:10 PM IchGucksLive: and test on this
12:10 PM gloops: psu Ichs?
12:10 PM IchGucksLive: https://www.ebay.de/itm/DE-Ship-DC24V-400W-16-7A-Switching-Power-Supply-for-Stepper-Motor-3D-Printer-CNC-/231657584763
12:10 PM IchGucksLive: its around you uk seller
12:10 PM IchGucksLive: stepper-online
12:10 PM gloops: thats lower than the ones i have
12:11 PM IchGucksLive: but more power
12:11 PM IchGucksLive: yu can only go 26V
12:11 PM IchGucksLive: 36
12:11 PM gloops: less volts to feed it in though?
12:11 PM gloops: i have got two 36v psu i could try one motor on each
12:12 PM IchGucksLive: its the amps what is your max cable length Z
12:12 PM IchGucksLive: oh thereare 2 PSU
12:12 PM gloops: cable length around 2metres
12:12 PM IchGucksLive: then it may be the setup
12:12 PM IchGucksLive: did you go into the ini and HAL
12:12 PM * fragalot thinks gloops should draw a little wiring diagram as there seems to be some communication mishaps
12:13 PM fragalot: gloops: your 36V 9,8A power supply; how many motors are connected to it?
12:13 PM IchGucksLive: he dident puffer the 5V i think
12:13 PM gloops: yes the hal and ini have been edited
12:13 PM gregcnc: the problem if everything si configured and working correctly comes down to motor current
12:13 PM gloops: fragalot 3 motors
12:13 PM IchGucksLive: 2200µf
12:13 PM gregcnc: well and actual coil voltage
12:14 PM IchGucksLive: gloops: does the VD supply 12V to the BOB
12:14 PM IchGucksLive: this will interfear
12:14 PM fragalot: gloops: 3x3,75A = 11.25A
12:14 PM gloops: Ichs VFD supplies 12v yes
12:14 PM IchGucksLive: fragalot: TIMES 0,7
12:15 PM IchGucksLive: gloops: then you got interfearences from EMF
12:15 PM gloops: i have had signs of interference yes
12:15 PM IchGucksLive: I HARDLY ADVICE TO GET the 12V from Main PSU
12:15 PM gloops: fragalot i can solve that, 2 psus, 2 motors to each
12:16 PM fragalot: gloops: if they're already there, that certainly can't hurt I think
12:16 PM IchGucksLive: gloops: on 5m/min you can go to 45000 per step
12:16 PM IchGucksLive: with no risk
12:16 PM gloops: the faster a stepper turns the more current it pulls, the stalling occurs when no more current available, or possible
12:17 PM IchGucksLive: didyou increse th RESET in HAL 500 more
12:17 PM gloops: i know these steppers can do more rpm, the Y is doing it already
12:18 PM gloops: no i didnt touch that Ichs
12:18 PM gregcnc: specs sheet for stepper?
12:18 PM IchGucksLive: so i gues the 5V is not clear
12:18 PM IchGucksLive: i woudt first make a SAVE Copy from the Config Mashine Folder
12:18 PM IchGucksLive: then interact
12:19 PM IchGucksLive: increse Parport reset
12:19 PM gloops: http://www.longs-motor.com/productinfo/detail_12_86_173.aspx
12:19 PM fragalot: IchGucksLive: out of interest, does the 0.7 factor always count, or does that assume that the power supply has a decent capacitor on it?
12:20 PM IchGucksLive: increse always
12:21 PM gloops: hey that psu has 14 amps!
12:21 PM gloops: the scammers sent me a 9 amps one
12:22 PM fragalot: 4.2A steppers too, rather than 3,75
12:23 PM gloops: yeah mine are 4.2 amp, i left them the setting under the max
12:23 PM fragalot: k
12:24 PM IchGucksLive: gloops: this reduces the power by 20%
12:24 PM IchGucksLive: give it the FULL
12:24 PM IchGucksLive: as RATED
12:24 PM uwe__ is now known as uwe_
12:24 PM IchGucksLive: if they got hot after 2hr then reduce but for 2hr on up to 65DEGC
12:24 PM gloops: as it stands now, i have motors on X (2) Y (1) i have only homed them and jogged them, the Y runs fine - but it is the only motor drawing higher current, no other motors are running
12:25 PM gloops: but the X axis jogs - 2 motors are pulling
12:25 PM IchGucksLive: gloops 400/R
12:25 PM IchGucksLive: or more microstepping
12:25 PM gloops: ill have a play at the weekend anyway, get the other psu on and split the drivers between them
12:26 PM gregcnc: yeah two PSU will quickly tell you if it's lack of power
12:29 PM gregcnc: what is stepper rpm at 2m/min?
12:29 PM gloops: erm let me open the calc
12:30 PM gloops: approx 160rpm
12:30 PM IchGucksLive: DIRSETUP = 8000
12:31 PM IchGucksLive: DIRHOLD = 4000
12:31 PM IchGucksLive: STEPLEN = 3000
12:31 PM IchGucksLive: STEPSPACE = 3000
12:31 PM IchGucksLive: as 6us = 166khz max
12:31 PM gloops: how do you work that out Ichs?
12:32 PM IchGucksLive: 3+3=6
12:32 PM IchGucksLive: 1second / 0,006us
12:32 PM IchGucksLive: 166khz
12:32 PM gloops: im sure my steplen is 999
12:33 PM IchGucksLive: with 500steps/mm = 20/25
12:33 PM gloops: this would also cause motor to stall?
12:33 PM IchGucksLive: the Driver neds 2000min
12:33 PM IchGucksLive: 25000 best
12:33 PM IchGucksLive: and 3000 save
12:33 PM fragalot: gloops: the datasheet of the driver states a pulse width of 2,5uS minimum, so round up to 3uS, or 3000.
12:33 PM IchGucksLive: 2500best
12:34 PM gloops: https://justpaste.it/1gkjv
12:34 PM fragalot: somehow though, the datasheet states 2,5uS pulse width, but allows a frequency of 300kHz which is a tad funny :D
12:35 PM IchGucksLive: and then with 500steps/mm and 166Khz 166000/500 = 332mm/second
12:35 PM IchGucksLive: = 20m/min
12:35 PM gloops: thats the hal
12:35 PM IchGucksLive: gloops: so do your HOMEWORK
12:36 PM fragalot: Nothing beats the german gründlichkeit
12:36 PM IchGucksLive: stepspace 0
12:37 PM gloops: well ive been very busy! only just got it moving, im looking at this now
12:37 PM IchGucksLive: DID you mesure 20000 latency
12:37 PM gloops: setp parport.0.reset-time 5000
12:37 PM IchGucksLive: increse by 500
12:37 PM gloops: that was the lower figure
12:38 PM gloops: no latency errors reported, or any other errors
12:38 PM IchGucksLive: THIS is why we use PID
12:38 PM IchGucksLive: also on steppers
12:39 PM gloops: setp stepgen.1.steplen 1
12:39 PM gloops: setp stepgen.1.stepspace 0
12:39 PM IchGucksLive: gloops: on this INI and HAL the Values are stored internal in the TRAJ
12:40 PM IchGucksLive: What is your BASEperiod SET in ini
12:40 PM IchGucksLive: servus Louis_Cypher
12:41 PM Louis_Cypher: Nabend
12:45 PM gloops: base period = 100 000
12:46 PM IchGucksLive: und du bist wirklich auf 2.8
12:46 PM gloops: [TRAJ]
12:46 PM gloops: COORDINATES = X Y Z
12:46 PM gloops: LINEAR_UNITS = mm
12:46 PM gloops: ANGULAR_UNITS = degree
12:46 PM gloops: DEFAULT_LINEAR_VELOCITY = 12.50
12:46 PM gloops: MAX_LINEAR_VELOCITY = 125.00
12:46 PM IchGucksLive: and you are realy on 2.8
12:46 PM gloops: yes its 2.8, the joints dont show on 2.7
12:47 PM gloops: STEPGEN_MAXACCEL = 937.5
12:48 PM IchGucksLive: STEPGEN_MAXACCEL = 300 MAX
12:49 PM gloops: why is that?
12:49 PM gloops: thats the max stepgen CAN acclerate isnt it?
12:51 PM IchGucksLive: gloops: you might get to 750
12:51 PM IchGucksLive: but first be shure it runs all
12:51 PM IchGucksLive: and no trouble on config
12:52 PM gloops: well i will have a look at the weekend
12:53 PM gloops: actually, an easy way to try the psu is simply to disconnect the Y driver
12:54 PM fragalot: yeah
12:55 PM IchGucksLive: fragalot: listen to him he makes the traps yu are going to be soon
12:55 PM fragalot: i'm not listening to him, i'm listening to you.
12:58 PM IchGucksLive: OH a realy big Fault !!
12:58 PM IchGucksLive: Noone lisens to me ?! ;-)
12:58 PM fragalot: it's not because I listen that I'll do what you say though :D
01:05 PM fragalot: evening miss0r
01:06 PM miss0r: goodevening fragalot
01:06 PM miss0r: Up to anything interresting?
01:06 PM fragalot: you missed my little shop tour earlier
01:06 PM miss0r: by whom?
01:07 PM fragalot: https://imgur.com/a/mmYRQ - https://imgur.com/a/4hvOk
01:08 PM miss0r: nice and tidy. Yours?
01:08 PM fragalot: aye, it could be tidier but that's halfway through a project
01:09 PM fragalot: being organized is not a luxury if you have limited space, lol
01:09 PM miss0r: Sweet. How big is that room? ( I have a hard time telling)
01:09 PM fragalot: 6x3m
01:09 PM miss0r: I hear'ya
01:09 PM miss0r: I would have guessed smaller from the pictures hehe
01:10 PM fragalot: well, 6x3 is the outside dimension
01:10 PM fragalot: there's 15cm of insuluation
01:10 PM miss0r: Mines 4x8.5 meters outside
01:11 PM fragalot: i'd love that little bit extra
01:11 PM miss0r: And I have no other insulation than what is offered by the type of light concrete the walls are made of
01:11 PM miss0r: Sure, I'd love to add a room the size of yours
01:11 PM * miss0r alwayzz wantzz more!!!
01:11 PM fragalot: hehe
01:11 PM fragalot: it's good to start off small though
01:11 PM miss0r: Indeed
01:11 PM fragalot: my old job had a HUUUGE workshop, and you could NOT work in there at all because it was so disorganized & cluttered
01:12 PM miss0r: I'm actualy doing some detailed CAD of the servo mounting now, I hope to do the first cuts on the mill within the hour
01:12 PM gloops: the thing is, i didnt actually choose these motors for this machine, i already had them, i assumed theyd be strong enough
01:12 PM miss0r: bah. That won't do
01:12 PM fragalot: need to finish the weld job you started yesterday? better carry out the hay bales they put on top of your project after you left. >.>
01:12 PM fragalot: miss0r: cool!
01:13 PM miss0r: The thing with a small workspace, mine ours - You can hardly leave a screwdriver out'a place without the whole thing looking cluttered
01:13 PM fragalot: gloops: they probably are once you fix the config like IchGucksLive's suggested, give the motors their full current, and split them over 2 PSU's
01:13 PM fragalot: miss0r: True, but at least you know where it is every time!
01:13 PM gloops: im still looking at the config, im not quite sure whats being suggested is hampering the power
01:14 PM miss0r: fragalot: What I realy need is a good place to store my projects while they are on hold, I CANNOT have any more half projects clutter up my workbench
01:14 PM fragalot: miss0r: same!
01:14 PM fragalot: miss0r: you should move here.
01:15 PM miss0r: What good would that do ? :S
01:16 PM fragalot: 2 things
01:16 PM fragalot: it gives you an opportunity to get something larger near me
01:16 PM fragalot: and since it's not in the UK it will be easier to work abroad soon.
01:17 PM miss0r: What ever gave you the impression I come from the UK ?
01:17 PM * fragalot stares into the distance
01:17 PM miss0r: <- Danish person
01:17 PM fragalot: close enough.
01:18 PM miss0r: i beg to differ ;)
01:18 PM fragalot: how about "cars are cheaper here" ?
01:18 PM miss0r: Now THAT we don't have
01:19 PM fragalot: I think my house cost me less here than my car would have in DK
01:19 PM fragalot: those "luxury" taxes are insane.
01:19 PM gloops: UK will soon be very low priced
01:19 PM miss0r: I have a counter offer for you. YOU move HERE :] I'll even let you borrow the lathe ;)
01:20 PM miss0r: I have a few ceramic inserts you can use to turn down that ballscrew of yours ;)
01:20 PM fragalot: miss0r: it's the surface grinder I'm interested in xD
01:20 PM miss0r: Sure, you can borrow that - Unser close supervision ;)
01:23 PM fragalot: Fair :)
01:23 PM miss0r: it was actualy DaViruz in here that gave me the link to buy it. He was interrested in it, but did not intend to buy it, so I grapped it :D Very nice price. I had it shipped from sweden
01:24 PM fragalot: Neat. I can't find anything that fits my size shop
01:24 PM miss0r: BUT.. if you ask him now, we will swear to god that I bought it right under his nose ;D hehe
01:24 PM miss0r: I think this one would. I bought it for its small size
01:24 PM fragalot: and now i'm at the point where I need to either re-organize, or get rid of something else first.
01:24 PM fragalot: miss0r: what model?
01:25 PM DaViruz: RIGHT under my nose.
01:25 PM miss0r: lol
01:25 PM miss0r: an EWM FBA2
01:25 PM fragalot: can't find anything about that on google
01:26 PM miss0r: DaViruz: right there when needed, ay?
01:26 PM DaViruz: I'll keep it in mind!
01:27 PM miss0r: fragalot: Right there in the corner: https://imgur.com/a/R0hy1
01:27 PM miss0r: DaViruz: You up to anything interresting?
01:27 PM DaViruz: not really :/
01:27 PM DaViruz: how's the EDM coming?
01:28 PM miss0r: Working on it right now, actualy.
01:28 PM fragalot: miss0r: that would indeed be just about the max size I could fit
01:28 PM miss0r: fragalot: Do you have logs that can show the imgur link I posted on the complete progress of the EDM ?
01:29 PM fragalot: I do not, but tom does
01:29 PM fragalot: http://tom-itx.no-ip.biz:81/~tom-itx/irc/logs/%23linuxcnc/
01:29 PM IchGucksLive: GN8
01:30 PM fragalot: I wouldn't mind having that grinder that gotteswinter has
01:31 PM miss0r: yeah
01:31 PM miss0r: DaViruz: I'm uploading a few pictures to imgur, hang on
01:32 PM DaViruz: i like your tool grinder, not seen one quite like it
01:33 PM miss0r: Its an older model. I got it for a 6 pack of beer. Plus it came with all sorts of equipment & a complete set of 5C collects. Plus I think 5 extra diamond wheels
01:34 PM fragalot: good deal, lol
01:34 PM miss0r: DaViruz: This is the progress of the EDm as of now: https://imgur.com/a/qwlvQ
01:34 PM fragalot: my grinder came with 2 worn down cup wheels and a singular Deckel style 8mm collet
01:35 PM fragalot: after looking up the price of those collets I decided to make an ER25 conversion collet
01:35 PM fragalot: and made a lot of lathe tool holder adapters
01:36 PM miss0r: I think that was a good way to go
01:37 PM miss0r: Althou, ER collects are not notorious for their accuracy
01:37 PM fragalot: neither are 2nd hand import grinders
01:37 PM miss0r: Hear hear
01:37 PM fragalot: I rebuilt the whole head for it, but haven't touched the spindle or the ... moving bar,
01:38 PM fragalot: whatever that's called
01:38 PM fragalot: I'm tempted to remake that like robrenz did
01:40 PM miss0r: I think you'd need a more rigid lathe to do any realy improvements to it :-/
01:40 PM fragalot: there are ways to work around that
01:40 PM miss0r: Unless you are seriously patient
01:40 PM fragalot: the lathe isn't super rigid, but it is pretty damn accurate
01:40 PM fragalot: there aren't that many original parts left on it that matter
01:43 PM miss0r: :]
01:43 PM miss0r: I have a lathe that looks alot like yours in my shed, collecting rust :-/
01:44 PM fragalot: same. :P
01:44 PM fragalot: I need to replace the little oil port on the left side of the leadscrew again
01:45 PM fragalot: the original sucked, but the replacement doesn't work well either because it's so hidden away behind sheet metal
01:53 PM miss0r: Transferring the first pocket for the CNC to cut
01:53 PM fragalot: :D
01:55 PM miss0r: I can't seem to find this information anywhere. I wonder what the duty cycle of this servo is. Can I just let it run forever, without it overheating? :S
01:56 PM fragalot: 2 ways to figure that out
01:56 PM fragalot: one involves reading, so that's probably not an option
01:59 PM miss0r: lol. I looked at the engrish manual, it did not give me any answers
02:00 PM fragalot: in that case, hit start & check the temperature periodically :-)
02:00 PM miss0r: I think i'll just buy a few to keep in stock :D
02:01 PM fragalot: miss0r: you could modify them to have water cooling running all the way around the stator & inside of the rotor
02:02 PM evilren: in the rotor?
02:02 PM evilren: i want to see that gasket
02:02 PM fragalot: :D
02:03 PM evilren: apex seal issue
02:04 PM fragalot: it's not that difficult really, all you need is a double walled concentric in & out port
02:04 PM gregcnc: rc servos aren't really rated for those kinds of things
02:04 PM fragalot: oh! THAT servo
02:04 PM * fragalot thought one of the cnc axis servos :P
02:05 PM fragalot: depends on the load I'd guess then
02:05 PM evilren: heh @ all you need is a double walled concentric in & out port
02:05 PM evilren: all i need is an extra $10k a year
02:05 PM fragalot: evilren: it's not a new concept
02:06 PM evilren: sure, but i wouldnt consider it easy, so likely not cheap
02:06 PM evilren: its what i had in mind
02:06 PM evilren: but i prob wouldnt do concentric rings i would just do one ring on each end
02:06 PM fragalot: one end is the business end though
02:07 PM evilren: sure but you can port on the sides somehow, shrug
02:07 PM fragalot: so you don't have any access to that, unless if you put a bayonet style ring on
02:07 PM evilren: both sides more compact, probably lighter, no return seems simpler to fab
02:07 PM evilren: right
02:10 PM miss0r: Damn annoying. This is the second mouse this year that has aquired a nasty double click feature
02:10 PM fragalot: miss0r: logitech?
02:10 PM miss0r: VERY annoying while doing CAD
02:10 PM miss0r: Dell, actualy
02:10 PM fragalot: my logitech mice do that too
02:11 PM miss0r: I hate it !
02:11 PM miss0r: First pocket done
02:11 PM fragalot: in Inventor if you double click the menu icon, it closes the program
02:11 PM miss0r: Starting on second pocket
02:11 PM fragalot: I really wonder what causes the double clickyness
02:12 PM fragalot: if it's just a cap gone wrong, or if it's designed to fail
02:13 PM gloops: right, disconnecting the Y motor definitely increased the hold, while stood the big pulleys are quite difficult to force step now
02:13 PM gloops: however still not getting a test as the noise? issue has returned
02:13 PM gloops: i also got a realtime delay error
02:13 PM miss0r: hmm... This one is bound for the scrap yard :) I hate throwing stuff out that can easily be fixed, but optic mice are so damn cheap
02:14 PM * fragalot is considering opening up his Logitech to see if he can fix it now
02:14 PM * miss0r hands fragalot a hammer
02:14 PM fragalot: tiny hammer.
02:14 PM gregcnc: was going to say hammer is a faster solution
02:15 PM fragalot: these are just outside of the "meh get another one" price range
02:15 PM fragalot: and apart from the doubleclick issue, I *LOVE* it
02:15 PM fragalot: nice man-sized mouse with some heft to it
02:16 PM gloops: the first thing in stepconfig, it asks for driver frequencies - where is that in the hal?
02:16 PM miss0r: I still have a micro$oft mouse (intelly mouse 3.0) Best damn mouse ever made!
02:17 PM miss0r: I've soldered new contacts into it twice and replaced the cord atleast three times
02:17 PM fragalot: lol
02:17 PM miss0r: It must be 15+ years old
02:17 PM miss0r: I know the feeling, I love that mouse
02:17 PM fragalot: this is a wired/wireless hybrid
02:18 PM gregcnc: how much do you computate that mice wear out?
02:18 PM fragalot: at least 8hrs a day
02:18 PM fragalot: then another few hours
02:21 PM miss0r: 2nd pocket done. Starting on 3rd
02:21 PM miss0r: No crashes yet :o
02:21 PM fragalot: how many pockets does it have?
02:23 PM miss0r: I've decided to break the three seprate cut depts up into three pockets
02:23 PM miss0r: For ease :)
02:23 PM miss0r: So, one, with some features
02:23 PM fragalot: Right.
02:24 PM miss0r: Will snap a picture after completing this run
02:27 PM miss0r: https://imgur.com/a/rb8En
02:27 PM miss0r: Looks like I have some deburring to do, lol
02:27 PM fragalot: and a lot of profiling xD
02:28 PM miss0r: hehe, Not to worrie :)
02:29 PM miss0r: The profiling will only tak 5.38mins
02:30 PM gloops: IchGucksLive> DIRSETUP = 8000
02:30 PM gloops: <IchGucksLive> DIRHOLD = 4000
02:30 PM gloops: <IchGucksLive> STEPLEN = 3000
02:30 PM gloops: <IchGucksLive> STEPSPACE = 3000#
02:30 PM gloops: oh god ive got to look at this sht and learn it
02:31 PM miss0r: gloops: The learning curve is quite steep with this stuff.
02:31 PM miss0r: If archivist has time, he is an excellent teacher with this stuff
02:31 PM gloops: miss0r steep and long
02:32 PM miss0r: but comming out on the other end, you will know you machine alot better than if it just worked off the bat
02:32 PM gloops: yes indeed, it has to be done
02:33 PM miss0r: Doing outer countouring... Fingers crossed
02:37 PM gregcnc: no deburring in the mill?
02:37 PM miss0r: Yeah sure, but you'd need a 5th axis to get thoes edges there completely cleaned up
02:38 PM fragalot: nah, get creative, orient the spindle correcly & use it as a shaper
02:38 PM miss0r: hehehe
02:38 PM gregcnc: i plan for that in the design, but not always for a simple part.
02:38 PM miss0r: I'd rather not :] I already spend waay too much time tramming the head as it is
02:39 PM miss0r: yeah, I would've had a hard time doing it here
02:40 PM gloops: steplen - assume is steplength, the amount of time the signal is on in nano seconds
02:40 PM miss0r: indeed
02:40 PM jym: I need to solder on a button, any suggestions? https://i.imgur.com/8c8oQbu.jpg
02:41 PM gloops: setp stepgen.0.steplen 1 < ive got 1 nano second signal
02:41 PM fragalot: jym: use quality flux & let the wicking effect do the work for you,
02:41 PM FinboySlick: jym: I suggest you don't mess it up ;)
02:42 PM jym: FinboySlick: Geee thanks ;)
02:42 PM jym: fragalot: ok
02:42 PM miss0r: jym: considered solder paste and baking it?
02:42 PM FinboySlick: It isn't too clear which are the contacts though. If they're the metallic sides, they seem awful close together down at the bottom.
02:42 PM jym: I wish I had some kapton tape though, any alternatives?
02:43 PM fragalot: I don't know of any good alternatives to kapton tape
02:43 PM fragalot: what do you need it for?
02:43 PM jym: miss0r: Not a chance in hell that's gonna hapen. the cellphone works just needs the button replaced.
02:43 PM jym: fragalot: heat shield
02:44 PM fragalot: meh
02:44 PM FinboySlick: jym: Aluminium foil is good heat shield.
02:44 PM jym: FinboySlick: you mean heat SINK
02:44 PM fragalot: dab on flux, tin one side, put in place & heat, solder other side, solder first side
02:44 PM fragalot: done
02:44 PM FinboySlick: If there isn't very good contact with the part you're trying to protect, it'll keep it from betting too hot while you're blasting with air.
02:45 PM fragalot: I don't like using hot air if i can help it
02:45 PM jym: FinboySlick: the cpu is right next to the button
02:45 PM fragalot: too many bad experiences with 0204 resistors going flying xD
02:46 PM jym: fragalot: that's what I fear, I dont have SMD tools at all, just a regualr soldering ron and a butane soldering iron with hot air tip
02:46 PM FinboySlick: jym: I re-soldered a BGA gpu on an ancient mac that way. Just cut a square in the foil big enough to expose the gpu and protected the rest of the board with the foil.
02:46 PM fragalot: jym: regular soldering iron works fine if the tip is small enough to fit in between the components
02:47 PM FinboySlick: Though that switch is too small for that to work.
02:47 PM jym: fragalot: of course it doesn't silly, that would make it way too easy =)
02:47 PM fragalot: jym: i've custom made some for my old iron before I got a new one
02:48 PM fragalot: jym: alternatively, solder switch on & wick away excess solder after the fact
02:48 PM jym: fragalot: Yeah, I have a 25W pencil iron I can reshap that might help things
02:49 PM fragalot: perfect.
02:54 PM jym: https://i.imgur.com/F2mXPbF.png
02:54 PM fragalot: add flux, and use copper braid (or copper wire) to wick away existing solder
02:55 PM jym: I have solder braid =)
02:55 PM fragalot: add thin layer of fresh solder on one pad, then add more flux & put the switch on, heat that pad so it sticks.
02:55 PM fragalot: then solder as normal
02:56 PM jym: Oh that reminds me, I need to finish mounting my pcb holder I made for this repair
03:01 PM gloops: define Imax?
03:01 PM fragalot: gloops: it's a 70mm film format.
03:01 PM gloops: in the context of stepper motors
03:01 PM gloops: input max?
03:02 PM fragalot: maximum current
03:02 PM gloops: so if the motors rated at 4.2 amps, Imax = 4.2
03:02 PM fragalot: Yes
03:02 PM gloops: right
03:03 PM gloops: well in that case my motors can only do 60 rpm according to this calculator
03:03 PM gloops: http://www.daycounter.com/Calculators/Stepper-Motor-Calculator.phtml
03:07 PM gregcnc: input data?
03:07 PM fragalot: mine should reach 360 according to that calculator
03:07 PM fragalot: guess I'll find out
03:07 PM gloops: http://www.longs-motor.com/productinfo/detail_12_86_173.aspx
03:07 PM gregcnc: yes but what did you enter?
03:09 PM gloops: Imax 4.2, L 6.8, Voltage 18, steps 400
03:09 PM fragalot: gloops: why 18?
03:09 PM fragalot: I thought you used 44V?
03:09 PM gregcnc: and why 400
03:09 PM gloops: i entered 18v because i assume the voltage is divided?
03:09 PM gloops: between drivers
03:09 PM fragalot: gloops: no.
03:09 PM gloops: 400 steps thats what theyre set for
03:09 PM gregcnc: this is for the motor itself
03:10 PM gloops: so 200 steps, the full steps
03:10 PM gregcnc: 36V source, 200 step
03:10 PM gregcnc: that page shows 3.0A? not 4.2
03:10 PM gloops: right..thats closer to 200 rpm
03:11 PM gloops: i dont think those are exactly the same as mine tbh
03:11 PM gregcnc: uh ok
03:12 PM gloops: well lets say around 180 ish, thats a working figure
03:12 PM gloops: minimum step time 1.6
03:12 PM gregcnc: don't worry about that step time
03:12 PM Tom_L: gloops you gettin anywhere yet?
03:13 PM gloops: Tom_L not had time to work on it, it moves fine, just trying to sort power matter out
03:13 PM gregcnc: RPM and torque available is what matters, in the curve
03:13 PM gloops: the hold has increased considerably by disconnecting y and upping to max amp setting, hard to force now
03:14 PM gloops: gregcnc well ichs and fragalot are saying step time and length are important
03:14 PM fragalot: gloops: for the DRIVE
03:14 PM gregcnc: that's timing for Linuxcnc and drivers
03:14 PM gregcnc: the motor has no idea
03:15 PM gloops: ive got 1 nano second steplen, it says there minimum step time 1.59
03:15 PM fragalot: basically the signal has to be loud and clear enough for the drive to process it
03:15 PM gloops: but isnt that time relevant for allowing current in?
03:15 PM fragalot: no
03:15 PM gloops: see ichs is reccomending 3000 steplen
03:15 PM gregcnc: the driver takes car of that those timing setting do not dtermine how the motor is operated
03:16 PM gregcnc: ich is trying to get the PC to talk to the driver clearly
03:16 PM gloops: i do seem to be having 'noise' symptoms now at higher speeds
03:17 PM gloops: can this minimal step time setting increase susceptibility to noise maybe?
03:17 PM fragalot: if it's too short, yes
03:17 PM gloops: yes, well mine is 1
03:17 PM fragalot: 1 what
03:18 PM gloops: steplen 1, 1 nano second
03:18 PM fragalot: your drives require a 2.5 micro second pulse
03:18 PM fragalot: so I'd set it at 3000
03:18 PM gloops: setp stepgen.0.steplen 1
03:19 PM gloops: i will do that next
03:19 PM fragalot: I'm surprised it works at all with 1 nanosecond, unless that parameter is overwritten elsewhere
03:19 PM gloops: thats in the hal
03:20 PM gloops: really, there is some force required to force these pulleys to miss steps when stood, im really surprised if there isnt enough power available
03:20 PM gregcnc: the load on the PSU is minimal what the stepper is static
03:21 PM gregcnc: the available torque is also maximum when the stepper is static
03:21 PM gloops: true yes
03:21 PM gloops: yes again
03:21 PM gloops: faster = lesser torque
03:21 PM fragalot: gloops: look at the .ods files at the bottom of this page. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration
03:22 PM gloops: that looks pretty informative fragalot thanks, ive been looking through the docs and got led to that calculator, i will read through that
03:24 PM fragalot: what confuses me is that in one part of the documentation they indeed state steplen = nanoseconds; however that page says steplen = base periods
03:30 PM gregcnc: "(float) stepgen.<chan>.steplen - Length of a step pulse (step type 0 and 1) or minimum time in a given state (step types 2-14), in nano-seconds. "
03:30 PM gregcnc: "Step type 0 is the standard step and direction type. "
03:31 PM fragalot: gregcnc: like I said, if you look at the page I linked last, there they talk about it like this: For example, if steplen is changed from 1 to 2, then it there will be two periods between the beginning and end of the step pulse. Likewise, if dirhold is changed from 1 to 3, there will be at least three periods between the step pulse and a change of the direction pin.
03:31 PM fragalot: Anyway, i'm off to bed. :-)
03:31 PM fragalot: gnite!
03:33 PM HighInBC is now known as Guest84511
03:33 PM gregcnc: step/dir uses step type 0 so steplen is periods per http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TweakingSoftwareStepGeneration
03:34 PM gloops: so steplen 1 is 1 full base period
03:36 PM gregcnc: yes, my step/dir machine is set up like this
03:36 PM Tom_L: STEPLEN = 1600
03:36 PM Tom_L: STEPSPACE = 2000
03:36 PM Tom_L: that's mine
03:36 PM gloops: thats yours tom?
03:36 PM gloops: lol, its all a bit confusing
03:36 PM gregcnc: tom what kind of driver?
03:36 PM Tom_L: gecko 203v
03:36 PM Tom_L: http://www.logosfoundation.org/instrum_gwr/bug/datasheets/G203V_Motor_Drive.pdf
03:36 PM gloops: i need to read up on this properly, but i will play with those numbers next time and see if anything noticeable happens
03:37 PM Tom_L: you using leadshine or some other driver?
03:38 PM gregcnc: my stuff looks wrong at this point but it's been ten years since I built this machine so i don't remember how I got these numbers
03:38 PM gloops: driver is DM542A, a leadshine copy i think
03:39 PM Tom_L: https://forum.linuxcnc.org/16-stepconf-wizard/29374-configuration-dm542a
03:40 PM gloops: blummin eck never thought of searching for that on the forums, i cant find any proper data anywhere like that
03:40 PM Tom_L: :)
03:40 PM gloops: saved page!
03:41 PM gloops: so i can try those settings thanks
03:41 PM Tom_L: it's not rocket science, just one's and O's
03:43 PM gloops: yeah, i can understand this im sure, ive never done anything before with this stuff though, and i am a kind of slow methodical learner, but i will get the hang of it eventually
03:43 PM Tom_L: DIRSETUP = 200
03:43 PM Tom_L: DIRHOLD = 200
03:43 PM Tom_L: that's also mine
03:44 PM gloops: setp stepgen.0.steplen 1
03:44 PM gloops: setp stepgen.0.stepspace 0
03:44 PM gloops: setp stepgen.0.dirhold 25000
03:44 PM gloops: setp stepgen.0.dirsetup 25000
03:44 PM gloops: thats the settings i have
03:44 PM Tom_L: you should do something about that
03:44 PM gloops: Step Time: 2000ns
03:44 PM gloops: _ Value of one step: 2000ns
03:44 PM gloops: _ Hold Direction: 2000ns
03:44 PM gloops: _ Setting management: 2000ns
03:44 PM gloops: thats his calculations
03:45 PM gloops: i will try them anyway
03:45 PM Tom_L: mine could be way off for all i know but it works
03:45 PM Tom_L: i think the step timing is pretty close though
03:46 PM gloops: mine is running ok at lower speeds, starts getting snaggled at faster speeds, seems a bit like 'noise' but mkaybe these settings are the cause
03:53 PM gloops: i think these settings are in nano seconds, 25000 was the max jitter i entered in the stepconfig - it wasnt that i just entered a higher number to be safe
03:53 PM gloops: dir is working fine, step is not
04:02 PM Deejay: gn8
04:18 PM miss0r: gloops: finish part. It took a while longer than I thought lol https://imgur.com/a/FzjEW
04:18 PM miss0r: It ended up taking me almost 3 hours to draw & cnc
04:20 PM gloops: looks pretty good miss0r
04:20 PM miss0r: Thanks. Good for a one-of anyway
04:21 PM gloops: 3 hours is probably not long for something like that i wouldnt have thought
04:22 PM gloops: i suppose for those who live in CAD the drawing would be quicker
04:26 PM miss0r: I ended up spending alot of time talking in here, so stuff takes more time then
04:41 PM miss0r: goodnight
04:53 PM Alkabal: hi all, do you know best driver for motor step ZEBOTRONIC ; AMP/Ph:3,5 ;Ohm/Ph:0,75 ; Type SM86 18.JJ.3.5 DNS3 ; <)=1,8°
04:55 PM Alkabal: this motor have 8 wire but wirered in // so have 4 wire if i have understand correctly in this mode they need 5A (60V to 120V)
04:55 PM Alkabal: and i'm not sure about peak and rms for leadshine
05:04 PM MrHindsight: 3.5A, 1.8°, 8 wire stepper?
05:05 PM MrHindsight: Alkabal: SM86 is not in their current catalog, is that the correct number?
05:06 PM MrHindsight: they have SM 56, 87, 88, 107 and higher
05:07 PM MrHindsight: wiring connections: http://www.stoegra.de/pdf/sm_anschluesse_e.pdf
05:08 PM Alkabal: thanks
05:08 PM Alkabal: but already wirered to //
05:08 PM MrHindsight: look for a 4A or higher stepper driver
05:08 PM Alkabal: 3.5A/phase but in // is 5A/phase
05:08 PM Alkabal: i have read is 5A in //
05:08 PM MrHindsight: ok then there you go
05:08 PM Alkabal: i have found datasheet
05:09 PM Alkabal: yes but is peak or rms ?
05:09 PM Alkabal: and 80v or need to found more power ?
05:10 PM MrHindsight: DM556 or DM856
05:10 PM MrHindsight: http://www.leadshine.com/series.aspx?type=products&category=stepper-products&producttype=stepper-drives&subtype=general-stepper-drives&series=dm
05:11 PM Alkabal: 556 is only 50v
05:11 PM Alkabal: but other is 80v
05:11 PM Alkabal: but only 4A ?
05:12 PM MrHindsight: I don't see your motor part number
05:12 PM Alkabal: RMS
05:12 PM MrHindsight: are you sure it's not a typo?
05:13 PM Alkabal: http://www.stoegra.de/pdf/sm86_2_e.pdf
05:14 PM Alkabal: the first one
05:14 PM MrHindsight: DM870
05:15 PM Alkabal: when configure 5A for RMS
05:15 PM Alkabal: or 4.8 peak ?
05:16 PM MrHindsight: max current consumption is just under 5A from the motors current chart
05:17 PM MrHindsight: sorry wrong one
05:18 PM MrHindsight: SM 86.2.18 is just under 3.2A at max
05:19 PM Alkabal: that i not understand
05:19 PM Alkabal: datasheet says 3.5 unipolr
05:19 PM Alkabal: 5A bipolar
05:19 PM Alkabal: for my knowledge bipolar = parralel
05:20 PM MrHindsight: yeah, odd data sheet
05:20 PM MrHindsight: could be that the chart is for unipolar mode
05:20 PM Alkabal: why ?
05:20 PM MrHindsight: send them an email and ask them to clarify
05:21 PM MrHindsight: het mister Stoegra, whats the current rating on this motor in bipolar mode? Peak and RMS values please
05:22 PM Alkabal: oh ok
05:22 PM MrHindsight: or just get the bigger stepper drive
05:22 PM Alkabal: not sure about peak and rms about this motor ok
05:22 PM Alkabal: bigger for accept 5A rms ?
05:22 PM Alkabal: or biggest
05:23 PM Alkabal: i think is better to not use a driver to is max
05:23 PM Alkabal: or i'm wrong
05:23 PM MrHindsight: DM870 7.0 (5.0 RMS) A
05:25 PM MrHindsight: the difference in price between the 5A and the 7A is $20
05:25 PM Alkabal: ok many thanks
05:25 PM MrHindsight: DM870 vs DM556
05:25 PM Alkabal: AM882 is a good choice too ?
05:26 PM MrHindsight: DM856 is $119
05:26 PM MrHindsight: right in between
05:26 PM MrHindsight: http://www.americanmotiontech.com/products/stepper-drives/digital-cnc-stepper-drives/ prices
05:26 PM Alkabal: 5.21A is dangerous ?
05:28 PM MrHindsight: http://www.leadshine.com/productdetail.aspx?type=products&category=stepper-products&producttype=stepper-drives&series=AM&model=AM882
05:29 PM Alkabal: 4.57 or 5.21 A
05:29 PM Alkabal: not exactly 5A
05:29 PM MrHindsight: mA are dangerous at high voltage
05:29 PM Alkabal: but except this i like the idea to not use to the max
05:34 PM Alkabal: sorry another question
05:34 PM Alkabal: EM806 is better ?
05:35 PM tiwake: MrHindsight: what about linuxCNC on bristol ridge?
05:36 PM MrHindsight: yes, it has the fancies controller
05:36 PM MrHindsight: tiwake: haven't worked with them yet
05:37 PM Alkabal: many thanks man !
05:37 PM MrHindsight: the RTAI dev stopped even trying to work with RTAI.org
05:37 PM MrHindsight: he did all the work the past few years and they never even wanted to give him credit
05:38 PM MrHindsight: tiwake: they might work fine since they are still Bulldozer
05:38 PM MrHindsight: might not
05:39 PM tiwake: piledriver technically, but yeah
05:40 PM MrHindsight: we get requests for RTAI ports or packages for other distros
05:40 PM MrHindsight: but nobody wants to pay for them
05:43 PM MrHindsight: even large guberment contractors
05:47 PM tiwake: RTAI?
05:48 PM MrHindsight: https://www.rtai.org/
05:48 PM MrHindsight: RTAI - the RealTime Application Interface for Linux
05:48 PM tiwake: oh that stuff
06:11 PM MrHindsight: https://www.fishersci.com/shop/products/eppendorf-tube-5ml-9/p-4669177 need to stuff plant fibers (e.g. cotton) into one of these with a consistent weight, 1 gram
06:12 PM MrHindsight: fibers are in a bunch like cotton balls
06:13 PM MrHindsight: weight has to be consistent
06:14 PM Alkabal: # these are in nanoseconds
06:14 PM Alkabal: DIRSETUP = 5000 # 5 uS leadshine dm556
06:14 PM Alkabal: DIRHOLD = 5000 # 5 uS leadshine dm556
06:14 PM Alkabal: STEPLEN = 2500 # 2.5 uS leadshine dm556
06:14 PM Alkabal: STEPSPACE = 2500 # 2.5 uS leadshine dm556
06:15 PM Alkabal: this setting are ok ?
06:16 PM Alkabal: for now i have this driver at home
06:16 PM Alkabal: and i'm not really sure about this setting at all
06:26 PM pcw_mesa: I would set the steptime and stepspace longer than the minimums ( say 3000 )
06:26 PM pcw_mesa: you can also use very long times for setup and hold without any performance issues ( 25000 will work on almost any drive )
06:27 PM Alkabal: ok top answear
07:06 PM FAalbers: 13.9 vs 15.1
09:11 PM ziper: can you cut threads on a second operation lathe
09:13 PM ziper: i'm wondering if this is a good deal https://miami.craigslist.org/brw/hvo/d/machine-shop-liquidation-sale/6487813392.html
09:29 PM MrHindsight: the picture of the lathe is too fuzzy
09:30 PM MrHindsight: https://images.craigslist.org/00Z0Z_fgqfFqi50Mk_1200x900.jpg
09:32 PM MrHindsight: likely just a turret and cross slide
09:33 PM MrHindsight: ziper: unlikely http://www.sterlingmachinery.com/media/brochures1/file/ramco-general-brochure.pdf page 32
09:34 PM ziper: do you think it is worth it for 400 (or maybe less if i lowball them
09:34 PM ziper: )
09:35 PM MrHindsight: can't really see it
09:36 PM MrHindsight: is works?
09:36 PM MrHindsight: was it used to catch water for the last 4 years?
09:37 PM MrHindsight: was it used as an anvil to straighter parts with a hammer?
09:37 PM MrHindsight: starighter/straighten
09:38 PM ziper: so i should lowball the shit out of them
09:53 PM ziper: or maybe this one, looks a little rough, says the motor is bad, asking 500 https://images.craigslist.org/00h0h_9RSPTPqXJwH_600x450.jpg
09:57 PM jesseg: that does look rough
09:57 PM jesseg: I think I'd want to see that in person before committing
09:58 PM jesseg: you do kind of want the ways to glide smoothly and the feed screw can come in handy too
10:33 PM CaptHindsight: ziper: that ones looks like it came from an aquatic environment
10:33 PM ziper: haha
10:34 PM ziper: florida is by and a large an aquatic environment
10:35 PM roycroft: moreso every day
