12:37 AM Deejay: moin
03:02 AM lcnc-relay: <TurBoss> morning
04:16 AM JT-Cave: morning
05:06 AM Tom_L: morning
05:07 AM lcnc-relay: <travis_farmer@> Morning
06:17 AM -!- #linuxcnc mode set to +v by ChanServ
06:45 AM JT-Cave: pcw--home, when would pid.s.maxoutput [SPINDLE_0]MAX_OUTPUT be different than hm2_7i96s.0.pwmgen.00.scale [SPINDLE_0]OUTPUT_SCALE
07:26 AM -!- #linuxcnc mode set to +v by ChanServ
08:27 AM pcw--home: It might be lower if you wanted to bound the analog output value to less than full scale, for example you have a 0..10V Spindle control but the power source is 12V so full scale PWM is 12V so for an imaginary 10K RPM spindle you would set the PWM scale to 12K but the PID max output to 10K (so you never get more than 10V out)
08:28 AM pcw--home: But this is such an uncommon thing, it doesn't seem like it needs to be set in a configurator
08:30 AM pcw--home: Too many options can make things look harder for beginners, and it can always be fixed later in the ini file
08:32 AM JT-Cave: thanks, I'm trying to figure out the simple way for the beginner to setup the 7i96s spindle
08:37 AM JT-Cave: what is a good starting value for pwm frequency? I see optimum PWM frequency is 10-20 KHz
08:37 AM JT-Cave: people often just take the default number for things
09:03 AM Tom_L: 1
09:03 AM Tom_L: take it or leave it
09:03 AM Tom_L: man it's humid out
09:04 AM Tom_L: cleaned up the fallen branches from overnite
09:05 AM Tom_L: got outta mowing anyway. too wet
09:07 AM JT-Shop: yup hot and muggy today
09:07 AM Tom_L: you think you may have pinpointed the deere's problem?
09:08 AM Tom_L: guess we won't really know until it starts
09:08 AM JT-Shop: I'm pretty sure it's the wires between the starter and the switch
09:22 AM JT-Cave: no rain for the next few days so I gotta get the surface grinder loaded up and delivered
09:24 AM Tom_L: how far down the road are they?
10:14 AM lcnc-relay: <skunkworks8841@> hmm
10:15 AM lcnc-relay: <skunkworks8841@> I wonder why I never grounded the plasma (shield) to anything - I guess It is grounded at the plasma.. maybe that was my thought
10:21 AM roycroft: there is apparantly a lot of smoke where i was planning on going today
10:21 AM roycroft: so maybe the road trip is off for today
10:35 AM pcw--home: 10 KHz is fine for the 7I96S
10:42 AM lcnc-relay: <skunkworks8841@> well - 1.5v is 75 in the plasmac.. that seems right. (the plasma says it has a 50:1 divider
10:43 AM lcnc-relay: <skunkworks8841@> (making sure polarity is right and such)
10:43 AM Tom_L: soon to have fresh new plasma videos?
10:43 AM lcnc-relay: <skunkworks8841@> maybe..
10:43 AM lcnc-relay: <skunkworks8841@> have to set all the hights and such
10:44 AM lcnc-relay: <skunkworks8841@> but so far so good
10:44 AM lcnc-relay: <skunkworks8841@> having 4 manuals open and trying to keep things strait.. lol
10:45 AM Tom_L: i know that feeling
10:46 AM lcnc-relay: <skunkworks8841@> what threw me off is there isn't an 'arc-ok' indicator on the gui.. which seems like an omission...
10:47 AM Tom_L: did you have one before?
10:47 AM lcnc-relay: <skunkworks8841@> I don't remember.. It was in path and very early plasma support.
10:47 AM lcnc-relay: <skunkworks8841@> *pathpilot
10:48 AM lcnc-relay: <skunkworks8841@> so - probably not
10:52 AM lcnc-relay: <skunkworks8841@> now I have to clean the crap off the table...
10:54 AM Tom_L: does 'arc-ok' come from the thcad board?
10:55 AM lcnc-relay: <.le_potato@> using switch/router will increase that much the timing?
10:55 AM lcnc-relay: <skunkworks8841@> no - not in this setup - the plasma torch has a arc-ok output
10:55 AM lcnc-relay: <.le_potato@> i mean latency
10:55 AM lcnc-relay: <skunkworks8841@> but - you could I think use the arc voltage
10:55 AM lcnc-relay: <skunkworks8841@> That is an option in plasmac
10:55 AM Tom_L: le_potato not sure what you're asking
10:56 AM Tom_L: oh, for ethernet you don't want anything between the card and the ethernet card
10:56 AM lcnc-relay: <skunkworks8841@> I would not use a switch between the computer and mesa
10:56 AM lcnc-relay: <.le_potato@> yes!
10:56 AM lcnc-relay: <.le_potato@> okay
10:56 AM Tom_L: just a cable
10:56 AM lcnc-relay: <.le_potato@> so for internet i need usb-lan
10:56 AM Tom_L: probably
10:56 AM lcnc-relay: <skunkworks8841@> yes
10:56 AM Tom_L: that's how i set up rpi
10:56 AM Tom_L: or wifi
10:56 AM lcnc-relay: <skunkworks8841@> righ
10:56 AM lcnc-relay: <skunkworks8841@> right
10:57 AM lcnc-relay: <.le_potato@> with nextcloud i sync the gcodes between computers
11:00 AM Tom_L: yeah i have a connection to my cad pc as well
11:00 AM Tom_L: most of the time i use tennis shoe net
11:01 AM lcnc-relay: <skunkworks8841@> the K&T has samba and I use it a lot to transfer files between machines... lol
11:02 AM lcnc-relay: <.le_potato@> what is k&t
11:02 AM Tom_L: kearny & trecker sp? cnc
11:03 AM lcnc-relay: <.le_potato@> ooooo
11:03 AM lcnc-relay: <.le_potato@> i paid like 6k for fanuc addon to enable ftp
11:07 AM Tom_L: comes free with linuxcnc
11:11 AM lcnc-relay: <skunkworks8841@> https://electronicsam.com/images/KandT/oldkandt.JPG
11:12 AM Tom_L: gotta love all the lab coats they wore back then
11:12 AM lcnc-relay: <skunkworks8841@> starlink went down for a bit...
11:12 AM Tom_L: that control is nearly bigger than the machine
11:13 AM lcnc-relay: <skunkworks8841@> lol - we ran that into the 2000's
11:13 AM Tom_L: tell me you made that smaller
11:14 AM lcnc-relay: <skunkworks8841@> nope.
11:15 AM lcnc-relay: <skunkworks8841@> lol - the new control? yes - it fits in the electrical box on the side of the machine
11:15 AM Tom_L: to think a rpi could run that beast
11:15 AM lcnc-relay: <skunkworks8841@> it could
11:15 AM lcnc-relay: <skunkworks8841@> but I would have to change from pci mesa cards
11:16 AM Tom_L: did that have servos or steppers?
11:19 AM lcnc-relay: <skunkworks8841@> servos
11:19 AM lcnc-relay: <skunkworks8841@> well - initally hydraluic servos
11:19 AM Tom_L: my bud had a bridgeport tracer that was hydraulic
11:20 AM Tom_L: initially did a bunch of die stamps with that thing
11:20 AM lcnc-relay: <skunkworks8841@> https://electronicsam.com/images/KandT/DSC_0242.JPG
11:20 AM Tom_L: for sheet metal
11:20 AM lcnc-relay: <skunkworks8841@> neat - I have seen tracers - but never ran one.
11:21 AM Tom_L: we move from that to digitizing mylars for a boss5 for them
11:21 AM Tom_L: most of the patterns weren't that critical for sheetmetal
11:21 AM lcnc-relay: <skunkworks8841@> the original control shared the x,z and b servo.
11:22 AM Tom_L: +-.030 on mylars usually
11:28 AM Tom_L: did a bunch of hydroblocks then as well
11:29 AM Tom_L: to form sheet over them with a high pressure bladder
11:33 AM lcnc-relay: <skunkworks8841@> wow - 7 years ago
11:33 AM lcnc-relay: <skunkworks8841@> https://www.youtube.com/watch?v=1GgOwPThYJY
11:35 AM Tom_L: never seen that one
11:36 AM lcnc-relay: <skunkworks8841@> yah - for whatever reason it is up on my other email..
11:37 AM lfluffywof is now known as fluffywolf
11:42 AM -!- #linuxcnc mode set to +v by ChanServ
12:01 PM Unterhaus__ is now known as Unterhausen
12:21 PM xxcoder: whoa that video
12:22 PM xxcoder: didnt expect it to turn on plasma cutter with dial indictor on it lol
01:11 PM lcnc-relay: <.le_potato@> can i drill holes in my machine for the home sensors?
01:12 PM lcnc-relay: <.le_potato@> for fitting it
01:19 PM Tom_L: le_potato, why not?
01:23 PM lcnc-relay: <.le_potato@> great!
01:23 PM lcnc-relay: <.le_potato@> i going to suck old coolant and oil from the machine
01:24 PM xxcoder: only suggestion I have is always check where you're going to add holes to, not to hit something on other side, and clearance for needed stuff like nuts or whatever
01:26 PM Tom_L: yeah, be smart about it :)
01:26 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/4YG5FAmZ8KDZwcq
01:27 PM lcnc-relay: <.le_potato@> i have a psu
01:30 PM rdtsc: re: sam's cnc plasma cutter - no poor DTI's were harmed in the making of this video :)
01:30 PM xxcoder: :)
01:33 PM rdtsc: that PSU looks like it belongs in a NASA flight deck :)
01:34 PM lcnc-relay: <.le_potato@> nah its a bench psu
01:34 PM rdtsc: 1 point 21 jiggawatts!
01:35 PM xxcoder: oh good you found my time machine psu
01:35 PM rdtsc: sam's got a flux capacitor, sure of it
01:36 PM rdtsc: all we need now is a user named DocBrown
01:39 PM DocBrown: Hey everyone. where is my lost PSU?
01:40 PM fluffywolf: lol
01:41 PM rdtsc: heheheh
01:41 PM DocBrown: 😄
01:42 PM rdtsc: for anyone wondering what the heck we're talking about: https://www.imdb.com/title/tt0088763
01:44 PM fluffywolf: my mill's psu is a random torroidal transformer I got on ebay, a bridge rectifier, and a random very overkill electrolytic cap.
01:45 PM fluffywolf: my bench psu is a lambda ems.... ems-40-15? I'd need to go over a check.
01:46 PM fluffywolf: https://radiosurplus.biz/strumenti/ems-power-supply-electronic-measurement-ems-40-15/ yeah, ems-40-15
01:48 PM rdtsc: my bench currently has an old-school https://www.chicagopartsnetwork.com/By-Location-/Chicago-/Motors-/Power-designs-inc-TP343B-triple-output-dc-power-supply.ASPX
01:49 PM fluffywolf: nice.
01:49 PM rdtsc: clunker though, lots of iron in it
02:05 PM fluffywolf: I have a newer multi-output one I need to fix... got it free at a yard sale. it has a "warning: outputs stuck at 41V!!!11!" written on it in sharpie.
02:05 PM fluffywolf: I'm assuming blown pass transistors.
02:17 PM lcnc-relay: <.le_potato@> i have about 0.06mm backslash thing in my axies
02:21 PM lcnc-relay: <.le_potato@> adding BACKLASH = 0.06 under [AXIS] why dosent work?
02:22 PM fluffywolf: that seems like normal/acceptable backlash
02:22 PM Tom_L: try under joint
02:23 PM lcnc-relay: <.le_potato@> help says under axis
02:25 PM lcnc-relay: <.le_potato@> i added under join and now my axis bumpy
02:26 PM lcnc-relay: <.le_potato@> is this using pid or what
02:26 PM lcnc-relay: <.le_potato@> it moves constantly
02:26 PM lcnc-relay: <.le_potato@> or STEPGEN_MAXACCEL
02:28 PM lcnc-relay: <.le_potato@> yeah, adjusted it, now looks good
02:31 PM lcnc-relay: <.le_potato@> but too much accel makes simple steps inaccurate
02:47 PM Tom_L: that's the disadvantage of backlash comp
02:47 PM lcnc-relay: <.le_potato@> adjusted it, looks good now
02:47 PM Tom_L: STEPGEN_MAXACCEL should be 1.5 - 2x MAX_ACCELERATION
02:48 PM lcnc-relay: <.le_potato@> yes
02:48 PM lcnc-relay: <.le_potato@> 2 was too much
02:48 PM lcnc-relay: <.le_potato@> but Y works perfect with 2
02:48 PM lcnc-relay: <.le_potato@> X only with 1.5
02:48 PM lcnc-relay: <.le_potato@> now i going to mill a notapenis
02:49 PM Tom_L: you want .001-.002" chipload for aluminum on a lighter machine
02:49 PM lcnc-relay: <.le_potato@> what is chipload
02:49 PM Tom_L: up to .004" chipload or maybe a bit more on a heavy one
02:49 PM Tom_L: material removed per tooth
02:50 PM Tom_L: so for a 3 flute that would be .003" per rev
02:50 PM Tom_L: as a guideline
02:50 PM Tom_L: all sorts of variables come into play
02:51 PM Tom_L: https://gdptooling.com/chipload-calc/
02:52 PM lcnc-relay: <.le_potato@> 0.082 chipload is too much?
02:52 PM Tom_L: mm?
02:52 PM lcnc-relay: <.le_potato@> wait this is meters/minute
02:53 PM Tom_L: yeah do the math :)
02:53 PM Tom_L: that's roughly .003"
02:53 PM lcnc-relay: <.le_potato@> my chipload is 0.000
02:53 PM Tom_L: got an android phone?
02:54 PM lcnc-relay: <.le_potato@> yes
02:54 PM Tom_L: DL FSWizzard
02:54 PM Tom_L: https://app.fswizard.com/
02:55 PM lcnc-relay: <.le_potato@> there is no metric in this
02:55 PM Tom_L: there is
02:55 PM Tom_L: select units
02:55 PM lcnc-relay: <.le_potato@> where
02:56 PM lcnc-relay: <.le_potato@> ah
02:56 PM lcnc-relay: <.le_potato@> isee
02:57 PM Tom_L: select the material etc
02:57 PM Tom_L: type of cutter
02:58 PM Tom_L: you don't need the pro version.. free is fine, pro just gets you more material types etc
02:58 PM lcnc-relay: <.le_potato@> yeah
02:58 PM Tom_L: but it's a pretty good calc
02:59 PM Tom_L: with other features as you can see
03:01 PM Tom_L: you can machine a turd this time
03:02 PM lcnc-relay: <.le_potato@> haha
03:02 PM lcnc-relay: <.le_potato@> what is requested tool 2 not found in the tool table?
03:03 PM lcnc-relay: <.le_potato@> i added 4 tool
03:03 PM lcnc-relay: <.le_potato@> N25 T2 M6
03:22 PM Tom_L: you can also manually edit that file
03:24 PM Tom_L: if you edit the tool table you may need to reload it for lcnc to see the changes
03:26 PM Tom_L: http://linuxcnc.org/docs/stable/html/gui/tooledit.html
03:28 PM lcnc-relay: <.le_potato@> yeah, i did the same
03:30 PM Tom_L: on a mill typically the columns used are Tool, Poc, Z, Diam and maybe a comment
03:30 PM Tom_L: you can set the displayed columns in the ini entry
03:31 PM lcnc-relay: <.le_potato@> thats what i dif
03:31 PM lcnc-relay: <.le_potato@> did
03:31 PM lcnc-relay: <.le_potato@> and dont find it,lol
03:31 PM Tom_L: i usually leave X and Y in case they accidentally get filled other than 0
03:31 PM Tom_L: that's not good
03:32 PM Tom_L: at least you can see their values are nil
03:35 PM Tom_L: in the ini [EMCIO] Section
03:35 PM Tom_L: TOOL_TABLE = tool.tbl - The file which contains tool information, described in the User Manual.
03:35 PM Tom_L: in the config directory
03:42 PM lcnc-relay: <.le_potato@> ty tom ill check it again
03:43 PM Tom_L: make sure you save & reload
03:51 PM roycroft: well i'm glad i decided against the road trip today
03:51 PM roycroft: when i was going into town my clutch started slipping
03:51 PM roycroft: it's been on the verge of slipping for a long time - probably since i bought the car
03:51 PM roycroft: but now it's time for a clutch
03:51 PM roycroft: i can still drive it, but i do not want to drive it far or in a remote area
03:52 PM fluffywolf: I just did mine. Got a Spec Stage 1.
03:53 PM roycroft: i just hope it's not too expensive and that it doesn't take too long
03:54 PM fluffywolf: if you're taking it to a shop, it's always expensive. lol
03:54 PM roycroft: i doubt the repair shop here has the ability to face a flywheel, so if that's necessary it will add at least a couple days to the job as they send it down to eugene
03:54 PM roycroft: i'm not going to do a clutch replacement on a gravel driveway
03:54 PM roycroft: it's going to a shop
03:55 PM roycroft: and there is only one shop in this town
03:55 PM fluffywolf: I do all my work in the driveway... a nice piece of cardboard to lie on is nice if it's not soggy out.
03:55 PM roycroft: i could have it towed to eugene, but i do not want to do that, as i'd have to pay to have it towed back or find another way to get there
03:55 PM roycroft: i have never enjoyed working on cars
03:55 PM roycroft: i used to do it
03:55 PM xxcoder: can tow with your truck?
03:55 PM roycroft: but i was young and broke, and taking it to a shop was not an option
03:56 PM roycroft: i'd have to rent a tow dolly, xxcoder
03:56 PM * fluffywolf is old and broke
03:56 PM roycroft: and i would have to get the tow dolly in eugene and bring it back there when i'm done
03:56 PM fluffywolf: slipping clutches usually get worse slowly, not quickly... just stay in low gear and drive it?
03:56 PM xxcoder: is it cheaper than hire tower?
03:56 PM fluffywolf: as long as you don't let it slip, it won't get worse.
03:56 PM roycroft: so $50 or so to rent the dolly, and two trips to town at ~$40 each for fuel
03:57 PM roycroft: yeah, i'm ok driving it like this for a bit
03:57 PM fluffywolf: (if you let it contiually slip and smoke it, it'll get worse quite quickly... stay a gear lower so there's less torque on it)
03:57 PM roycroft: i can't use 6th gear unless the road is flat or sloping downhill
03:57 PM roycroft: so i ended up driving in 5th gear for most of the trip home
03:57 PM fluffywolf: I guess I don't understand why you're talking about towing it, then.
03:58 PM roycroft: no shop is going to repair it in a day
03:58 PM roycroft: if i drive it down to the shop i have to get home
03:58 PM roycroft: and then i have to get back to town to pick it up
03:58 PM fluffywolf: shop loaner or a rental?
03:58 PM roycroft: there's a bus from here to town, but it only runs 2x/day
03:58 PM roycroft: at inconvenient times
03:59 PM fluffywolf: heh, I didn't even think of busses, none go near my house. lol
03:59 PM roycroft: hopefully the shop in town can fix it
03:59 PM roycroft: i the town where i live, not in the real town
03:59 PM roycroft: they fixed the crankshaft position sensor for me, at a reasonable cost and with the car in the shop for only a day
04:00 PM roycroft: i'll find out monday
04:00 PM fluffywolf: depending on how popular your car is, may need to order your clutch in advance. certainly will if you want a performance option.
04:01 PM roycroft: i got some angle today to mount that other power supply in my controller cabinet, and got some materials to make some shelves in my office closet, so i can finally finish unpacking the office boxes
04:02 PM roycroft: i am guessing they will need a day to confirm that it's a clutch problem and drop the tranny to look at the clutch and determine what is needed
04:02 PM roycroft: and another day or more to get the parts
04:02 PM fluffywolf: I've wasted my morning making minor changes to my motor mount design in the buggiest cad program of all time... later today projects are re-organizing stuff to have access to the mill and gardening.
04:02 PM roycroft: and another day to install the new parts and reinstall the tranny
04:02 PM roycroft: and i have no interest in a "performance" clutch
04:02 PM roycroft: i'm not a car person
04:02 PM roycroft: cars to me are tools that i use to get things done
04:02 PM fluffywolf: since it's a 6 speed, I'll assume it's hydraulic, not cable or mechanical linkage, so slipping is about a 99.9% chance of needing a clutch kit.
04:03 PM roycroft: yes, it's hydraulic
04:03 PM roycroft: and yes, it almsot certainly needs at least some clutch components
04:03 PM roycroft: but i think they'll need to disassemble and inspect before knowing exactly which parts are needed
04:04 PM fluffywolf: (cable and linkage might just be out out of adjustment)
04:04 PM fluffywolf: nah. you just buy a kit. it comes with all the parts, and you replace all of them at the same time.
04:04 PM fluffywolf: you can be ultra cheap redneck and replace just the disc, but if you're going to a shop, you won't do that. heh.
04:04 PM roycroft: perhaps that is how it is done now
04:04 PM roycroft: in the past it was not
04:05 PM roycroft: and the flywheel will not be part of the kit anyway
04:05 PM roycroft: they'll need to inspect that to see if it needs to be resurfaced or not
04:06 PM roycroft: so i'm anticipating this will take at least 3 days from when they start work on it
04:06 PM Tom_L: option 2: drive the truck a while
04:07 PM roycroft: yes, i'll be driving the pickup while the car is in the shop
04:07 PM roycroft: but at 15mpg vs 40mpg i don't want to do that a lot
04:07 PM roycroft: it's a question of timing, not logistics
04:08 PM roycroft: i don't want the car in the shop during a period where i need to make 2 or more trips to town
04:08 PM roycroft: 1 at most
04:08 PM roycroft: and if possible 0
04:08 PM roycroft: but 1 is likely the number
04:08 PM Tom_L: i presume your truck repair is holding it's own
04:09 PM roycroft: it's doing fine
04:09 PM roycroft: this is another reason i'd like the local shop to fix it
04:09 PM roycroft: if i take it to a shop in eugene, i'll make an appointment to drop it off/have it delivered
04:09 PM roycroft: once it arrives it will go in the queue
04:09 PM roycroft: and a few days later will rise to the top of the queue, where they will start work on it
04:10 PM roycroft: it will be there at least a week
04:10 PM roycroft: the local place will put me in the queue, and call me when it's my turn, and i'll drop the car off then
04:11 PM roycroft: which is how it should be at all auto repair shops, but for whatever reason they don't like to do it that way
04:11 PM roycroft: they would rather inconvenience people as much as possible
04:13 PM fluffywolf: what is your car, anyway?
04:13 PM fluffywolf: I've never been to a shop, so I don't know how they schedule things around here.
04:18 PM roycroft: 2012 veloster
04:19 PM roycroft: it's a fake sports car
04:19 PM roycroft: i'm not into sports cars, but i like cars that are small and have good fuel economy
04:19 PM roycroft: the veloster is both
04:19 PM Tom_L: got rid of the prius
04:20 PM roycroft: yes, the repair would cost more than the car was worth
04:20 PM xxcoder: mines ford focus 2012
04:20 PM roycroft: this after i had just put $1500 into it
04:20 PM roycroft: like days later
04:20 PM fluffywolf: ... why is your clutch kit half the price of mine? lol
04:20 PM fluffywolf: good news. parts for that are fucking dirt cheap, and kits usually include a new flywheel.
04:20 PM roycroft: i know when to stop putting money into a car
04:21 PM fluffywolf: s/usually/often
04:21 PM roycroft: because it's a fake sports car, not a real sports car
04:21 PM roycroft: i'm anticipating the repair will be between $1500 and $2000
04:22 PM Tom_L: is it rwd?
04:22 PM fluffywolf: it's a hyundai.
04:24 PM roycroft: fwd for my model year
04:24 PM roycroft: later velosters are rwd
04:24 PM roycroft: starting in 2015, i think
04:24 PM fluffywolf: oh, they actually made a rwd one? my bad.
04:24 PM Tom_L: so they probably have to drop the whole thing out
04:24 PM roycroft: possibly
04:24 PM fluffywolf: I've always assumed all hyundai are fwd.
04:24 PM Tom_L: to separate it
04:25 PM fluffywolf: with how cheap they are, if you tell your mechanic to order a kit with a flywheel, you can be sure the entire process will be done in one step with no machine shop delay.
04:25 PM roycroft: it looks like aftermarket clutch kits without the flywheel are only about $300
04:25 PM fluffywolf: a new flywheel for those costs less than visit to the machine shop.
04:26 PM roycroft: but i would guess there's at least $1k in labor
04:26 PM roycroft: i'll talk to the shop on monday and see what they recommend and what they quote
04:26 PM fluffywolf: machine shop charged me $100 last time I went to one... and you can get a whole kit, with flywheel, for $160. lol
04:26 PM roycroft: if i still had my lathe i could them hand me the flywheel, i would take it home, and resurface it for them
04:26 PM roycroft: but i don't so i can't
04:27 PM fluffywolf: I sold my brake/flywheel lathe a while back.
04:27 PM roycroft: i just had a 12x36 machine shop lathe
04:27 PM roycroft: but i could have surfaced a flywheel on it
04:27 PM roycroft: if my mill were bigger i could do it on that
04:27 PM roycroft: but i would not recommend that - a lathe woudl be much better
04:28 PM fluffywolf: I had my clausing 12x36 sold on me...
04:28 PM roycroft: i'm assuming the flywheel on the veloster is 12" or smaller
04:28 PM roycroft: since everything on that car is small
04:28 PM fluffywolf: (I had it and my mill at someone else's place, and they told me I had to move them immediately or they were going away, and I couldn't move them immediately...)
04:29 PM xxcoder: flywheel in o'reilly 109 bucks
04:30 PM fluffywolf: $109 for you is like $79 for a mechanic.
04:30 PM * roycroft heads out to make some brackets for his 48v psu
04:30 PM xxcoder: "clutch flywheel" if that makes a difference
04:30 PM roycroft: and they will charge me the full $109
04:30 PM fluffywolf: (I have an oreilly commercial account, but I'm not going to call them up to get a quote for a random irc chat. lol)
04:30 PM roycroft: and i don't care
04:30 PM roycroft: as long as they don't charge me more than retail
04:30 PM xxcoder: well retail seems reasonable
04:31 PM fluffywolf: yeah, as I said, it's cheaper to get a new flywheel than to take the old one to the machine shop.
04:31 PM roycroft: anyway, i'm heading out
04:31 PM roycroft: i've been in town all morning, and i want to get some stuff done today
04:31 PM xxcoder: have fun
04:31 PM fluffywolf: so just order the whole kit in advance, then no inspection or wait needed.
04:31 PM fluffywolf: cyas
04:31 PM Tom_L: only thing left is to do
04:33 PM fluffywolf: I had mine refinished because it's a custom job and not readily available... and I'd been through 4 discs since last time it was refinished.
04:33 PM Tom_L: maybe you're just hard on equipment :)
04:34 PM fluffywolf: I measured the step depth at .823 at the edge and .831 in the middle, so I figured it had enough uneven wear it was worth turning it back to spec.
04:34 PM fluffywolf: Tom_L: I drive 150 miles a day.
04:34 PM fluffywolf: not highway.
04:34 PM fluffywolf: dirt and twisties.
04:34 PM Tom_L: fair enough
04:34 PM xxcoder: lot more stress when not highway even if smooth roads
04:34 PM fluffywolf: and I'm making twice stock horsepower. :)
04:34 PM xxcoder: accels and decells
04:35 PM Tom_L: 2x more than you likely need
04:35 PM fluffywolf: one of those discs I blew up dragging a superduty out of the mud...
04:35 PM fluffywolf: Tom_L: nah. my car was exceptionally underpowered stock. heh.
04:35 PM fluffywolf: 83hp!
04:35 PM fluffywolf: lol
04:35 PM Tom_L: so were the parts it was driving
04:36 PM lcnc-relay: <skunkworks8841@> I am still happy with my jetta 1.4l turbo
04:36 PM fluffywolf: not really... the transmission is good for like 500hp...
04:36 PM Tom_L: maybe you need a multi plate clutch setup
04:36 PM xxcoder: new tranny for your vehicle?
04:36 PM fluffywolf: subaru overengineering everything then put a tiny engine in front of it.
04:37 PM xxcoder: ah lol
04:37 PM lcnc-relay: <skunkworks8841@> a tiny engine with lots of head gasket problems
04:37 PM Tom_L: they had issues with their piston ring lands being too thin too
04:37 PM fluffywolf: the subaru transmission is basically unchanged from 1985 (with 83hp cars) to present (with twin turbo STI drift machines...)
04:38 PM fluffywolf: my car is a mix of parts from all different years.
04:40 PM Tom_L: skunkworks, deer seem to like it too
04:42 PM lcnc-relay: <skunkworks8841@> deer and other vehicles?
04:42 PM lcnc-relay: <skunkworks8841@> no clue what happened to it initally
04:42 PM fluffywolf: I had a good clutch, which lasted a long time, then I blew it up dragging the superduty. I got the superduty out of the mud just fine, and if I'd stopped then, all would have been good, but I tried pulling it up the ramps onto his equipment trailer, and I was stuck between his other truck and a tree and didn't want to risk wheelspin and sliding into his truck, so I was using all clutch.... and cooked it.
04:43 PM fluffywolf: then I got an OEM clutch, but it couldn't handle the torque, so it was slipping from the day I put it in. then I ordered a south bend stage 2 dd clutch, but they sent the wrong pressure plate, so I put the high friction disc in with the oem pressure plate, and drove that for a while, but it never grabbed as well as I would have liked. now I have a spec stage 1, and it seems nice.
04:44 PM fluffywolf: it's always fun to un-stuck people with a subaru. they invariably, without fail, claim you'll never move their vehicle with a car, and then you drag them out. :P
04:55 PM lcnc-relay: <.le_potato@> skunkworks8841@ 1.4 tfsi?
04:57 PM lcnc-relay: <skunkworks8841@> uh.. 2017 vw with the base model engine
04:58 PM lcnc-relay: <skunkworks8841@> direct injected turbo
04:59 PM lcnc-relay: <skunkworks8841@> a whole 150hp.. (it is actaully pretty fun to drive - it is a manual)
05:03 PM lcnc-relay: <.le_potato@> works until it works, lol
05:03 PM fluffywolf: is that one of the ones vw wants to reprogram so it sucks?
05:03 PM lcnc-relay: <.le_potato@> Tom_L: in ladder editor i can do programming?
05:03 PM lcnc-relay: <.le_potato@> like enable output every 5 sec to enable it for 1 sec if axis moving?
05:05 PM lcnc-relay: <.le_potato@> fluffywolf those was the diesel models
05:06 PM fluffywolf: oh, for some reason I was thninking you said a diesel.
05:06 PM Tom_L: le_potato, yes but i've never used it
05:08 PM lcnc-relay: <.le_potato@> tfsi is petrol, crtdi is diesel
05:11 PM fluffywolf: I wish the subaru diesel was easy to get.
05:15 PM lcnc-relay: <.le_potato@> subaru diesel is totally shit
05:15 PM lcnc-relay: <.le_potato@> 90% subaru diesel here
05:16 PM fluffywolf: the people I've talked to have liked it. good power, exceptional economy. in what way is it shit?
05:16 PM fluffywolf: they were never sold here and are essentially illegal here, so I've never seen one in person.
05:16 PM lcnc-relay: <.le_potato@> maybe not the same diesel
05:17 PM fluffywolf: they only made one, as far as I know.
05:17 PM fluffywolf: EE20
05:17 PM lcnc-relay: <.le_potato@> the crankshaft breaks in all of them
05:18 PM * JT-Shop saw an OAT of 100°F on the way home
05:19 PM fluffywolf: I thought that was only the first year, and they fixed them?
05:20 PM fluffywolf: " It is known for the '07~'08 to have bottom end problems including broken cranks and spun rear main bearings."
05:23 PM fluffywolf: 5.7L/100km sure sounds nice...
05:23 PM fluffywolf: (for a full-size AWD wagon with good power)
05:26 PM fluffywolf: bbl, food time
06:18 PM roycroft: well, that is significant progress
06:19 PM roycroft: the new spindle psu is installed, and while i haven't gotten back to the tachometer problem and don't know exactly how fast the spindle is spinning, it's significantly faster than before, like 2x as fast, as would be expected
06:20 PM xxcoder: nice. I bet it ramped much faster too
06:20 PM roycroft: yes
06:20 PM roycroft: the jst connector is still 5v though
06:20 PM xxcoder: youre probably right that external is 10v but internal is 5v
06:20 PM roycroft: but that is fine, as connecting it to the mesa board works well, and i'm sure i'm getting full speed from it
06:21 PM lcnc-relay: <.le_potato@> 48v psu roycroft?
06:21 PM roycroft: that still seems odd to me, but as the saying goes, ours it not to wonder why. ours is to deal with what is :)
06:21 PM roycroft: yes, .le_potato@
06:21 PM lcnc-relay: <.le_potato@> better start now?
06:22 PM roycroft: i switched a 24v psu for a 48v psu
06:22 PM roycroft: and yes, it starts up much faster now
06:22 PM lcnc-relay: <.le_potato@> or lights still dimming
06:22 PM xxcoder: that was my crappy house power system, not his
06:22 PM lcnc-relay: <.le_potato@> oh
06:22 PM xxcoder: his router is formerly mine
06:22 PM lcnc-relay: <.le_potato@> sold with 5x profit?
06:22 PM xxcoder: nah 100x
06:23 PM roycroft: he actually gave it to me
06:23 PM xxcoder: well for him its essentally infinite profit. divide by 0
06:23 PM roycroft: i bought something else from him, and he threw in the router and a delta printer kit
06:23 PM lcnc-relay: <.le_potato@> and $5k
06:23 PM roycroft: which was not always a kit, but it is now
06:23 PM roycroft: the router was a kit as well
06:23 PM roycroft: but i've almost turned it into a working machine
06:23 PM xxcoder: yeah delta one definitely need repairs. kossel clear so its fairly historic for 3d printer.
06:24 PM roycroft: which i think is why xxcoder gave it to me
06:24 PM roycroft: he wanted it working again
06:24 PM lcnc-relay: <.le_potato@> delta servo?
06:24 PM roycroft: and he wasn't going to do it
06:24 PM xxcoder: yeah no room and all
06:24 PM roycroft: i'm not sure i'll ever do much with that delta printer
06:24 PM lcnc-relay: <.le_potato@> oh delta printer
06:24 PM roycroft: but i want to get it working again, controlled by linuxcnc
06:24 PM roycroft: it deserves another life
06:25 PM roycroft: it's an historic machine
06:25 PM xxcoder: with real jhead hotend
06:25 PM roycroft: maybe some day there will be a 3d printer museum, and i'll donate it
06:25 PM lcnc-relay: <.le_potato@> did u guys used ladder editor?
06:25 PM roycroft: not i
06:25 PM xxcoder: which probably need to be cleared and cleaned to work again
06:26 PM roycroft: i used mesact for initial configuration of the router, and i'm editing the hal and ini files by hand now
06:26 PM lcnc-relay: <.le_potato@> i need something example to understand it
06:26 PM xxcoder: yeah its very simple machine overall
06:26 PM lcnc-relay: <.le_potato@> like i want to enable a relay every 5sec for 1sec if axis moving
06:26 PM lcnc-relay: <.le_potato@> its for lube oil
06:27 PM roycroft: that is probably far too often to lube your machine
06:27 PM lcnc-relay: <.le_potato@> im not sure where to program it, or python or what
06:27 PM lcnc-relay: <.le_potato@> it was an example
06:27 PM JT-Shop: you can do that in classicladder
06:27 PM lcnc-relay: <.le_potato@> and how can i enable it?
06:28 PM lcnc-relay: <.le_potato@> its grayed out
06:28 PM JT-Shop: it?
06:28 PM lcnc-relay: <.le_potato@> i cant click on in
06:28 PM lcnc-relay: <.le_potato@> inactive item
06:28 PM JT-Shop: what is inactive?
06:29 PM lcnc-relay: <.le_potato@> AXIS Gui -> File -> Ladder Editor
06:29 PM JT-Shop: ah ok, how did you make the configuration?
06:30 PM lcnc-relay: <.le_potato@> by hand
06:30 PM JT-Shop: ok
06:31 PM lcnc-relay: <.le_potato@> i used that other wizard but after that by hand
06:31 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/MGweQhww6EipKaeg7
06:31 PM JT-Shop: http://linuxcnc.org/docs/stable/html/ladder/classic-ladder.html#_loading_the_classicladder_non_realtime_module
06:31 PM JT-Shop: you have to load classicladder to be able to edit it and use it
06:32 PM JT-Shop: sam what am I looking at?
06:32 PM lcnc-relay: <skunkworks8841@> First plasma cut
06:33 PM lcnc-relay: <skunkworks8841@> 1" circle
06:33 PM JT-Shop: nice
06:34 PM lcnc-relay: <.le_potato@> JT-Shop that in docs doesn't work
06:34 PM JT-Shop: what does it do when you add that to your hal file?
06:35 PM lcnc-relay: <.le_potato@> nothing
06:37 PM lcnc-relay: <.le_potato@> I have a feeling the doc is not up to date.
06:37 PM lcnc-relay: <.le_potato@> i only make questions here if something doesnt work as it should, lol, like backlash
06:37 PM lcnc-relay: <.le_potato@> like docs says put at [axis] but apprenetly have to be at [joint]
06:39 PM JT-Shop: loadrt classicladder_rt
06:39 PM JT-Shop: addf classicladder.0.refresh servo-thread
06:40 PM JT-Shop: that's what step conf wizard creates
06:40 PM JT-Shop: # Load Classicladder without GUI (can reload LADDER GUI in AXIS GUI
06:40 PM JT-Shop: loadusr classicladder --nogui custom.clp
06:40 PM JT-Shop: and that line
06:40 PM lcnc-relay: <.le_potato@> HALUI = halui
06:40 PM lcnc-relay: <.le_potato@> this need as well
06:41 PM JT-Shop: to use halui pins yes that is needed
06:41 PM lcnc-relay: <.le_potato@> ty JT-Shop, but why docs says different?!
06:41 PM JT-Shop: ask the people that now take care of the docs... I no longer do that
06:43 PM lcnc-relay: <.le_potato@> like, nobody?
06:43 PM JT-Shop: seems more like everybody
06:43 PM lcnc-relay: <.le_potato@> hmm
06:44 PM lcnc-relay: <.le_potato@> should i 'report' these or useless?
06:44 PM JT-Shop: best is to do a pr I think
06:45 PM JT-Shop: after all linuxcnc is a totally non funded volunteer project
06:47 PM lcnc-relay: <.le_potato@> i do pr, ty!
06:48 PM JT-Shop: thank you for helping
06:52 PM lcnc-relay: <.le_potato@> luv u
06:53 PM pcw--home: Lubrication could be done just with hal components
06:54 PM roycroft: i still would not be squirting lube 17% of the time the machine is running
06:55 PM lcnc-relay: <.le_potato@> at every minute its need a drop
06:55 PM pcw--home: say siggen + oneshot
06:56 PM lcnc-relay: <.le_potato@> as i watching docs, hal file programming easier than this ladder thing
06:56 PM lcnc-relay: <.le_potato@> oneshot + limit3, no?
06:56 PM * roycroft ponders going back to work on the encoder issue
06:57 PM pcw--home: you could even get fancy and make the rate proportional to velocity
06:57 PM lcnc-relay: <.le_potato@> i drained the oil today, it was not oil anymore, lol
06:59 PM JT-Shop: https://youtu.be/Pl1ytAcjQmc?t=1229
07:01 PM lcnc-relay: <.le_potato@> JT-Shop i do this sometimes from pcb soldering machine
07:01 PM lcnc-relay: <.le_potato@> its have lead bath
07:02 PM JT-Shop: cool
07:15 PM lcnc-relay: <skunkworks8841@> seems to to thc and everything.
07:15 PM lcnc-relay: <skunkworks8841@> kinda cool
07:16 PM lcnc-relay: <skunkworks8841@> Tom_L: it does have a arc-ok light.. Just totally missed it
07:17 PM lcnc-relay: <skunkworks8841@> now I need to draw up some brackets and see
07:18 PM pcw--home: so proportional lube: motion.current-vel --> scale.in --> scale.out --> siggen.frequency --> siggen.clock --> oneshot
07:19 PM lcnc-relay: <skunkworks8841@> lol - hal is cool
07:19 PM pcw--home: --> lube relay output
07:20 PM lcnc-relay: <.le_potato@> pcw--home: https://pastebin.com/5X77y2q2
07:20 PM lcnc-relay: <skunkworks8841@> pcw--home: EMC1 board seems to work just fine
07:23 PM lcnc-relay: <skunkworks8841@> I used the pncconfg to setup qtplasmac as there is a lot of integration. Picked a mesa card that had the step/gens and enough pins. I only had to change one pin - and then the name of the actual card and it just worked
07:30 PM pcw--home: Yeah, there aren't many things that are card specific except GPIO
07:31 PM pcw--home: Using the EMC1 on plasma?
07:42 PM roycroft: i'm making some progress - the led on the hall sensor flashes on and off now
07:43 PM roycroft: i had aligned the new bracket where the old one was, but the old one had probably slipped, because when i took the fan off to locate the magnets, they were not anywhere near in line with the sensor
07:43 PM roycroft: now they are
07:43 PM xxcoder: ohh hopefully its one that works at max rpm
07:43 PM roycroft: that i still don't know
07:43 PM roycroft: the fluke isn't reading the pulses well
07:43 PM roycroft: when it's barely moving the fluke thinks it's over 100Hz
07:44 PM roycroft: and when it's at jet engine sound speed the fluke thinks it's about 450Hz
07:44 PM lcnc-relay: <.le_potato@> sup with your hall sensor?
07:44 PM roycroft: wait, that might be right
07:44 PM roycroft: it should be 400Hz if it's running at 12000rpm with two magnets
07:45 PM roycroft: so i guess that's close enough
07:45 PM xxcoder: error at low bound sounds weird
07:45 PM roycroft: yeah
07:45 PM roycroft: so i guess the next step is to figure out how to connect to the mesa board and see how fast linuxcnc thinks it's spinning
07:46 PM roycroft: which i think will be pretty straightforward
07:46 PM xxcoder: so I guess that dc-dc was fine also
07:47 PM roycroft: i don't know
07:47 PM roycroft: i'm still using the bench ps
07:47 PM xxcoder: ahh ok
07:47 PM roycroft: i like to change one variable at a time
07:47 PM roycroft: 'cuz i'm not clever enough to deal with multiple variable varying simultaneously
07:47 PM xxcoder: smart really
07:48 PM lcnc-relay: <.le_potato@> roycroft what are you trying to do
07:48 PM lcnc-relay: <.le_potato@> meassure rpm?
07:48 PM roycroft: yes
07:48 PM roycroft: and i have done that now
07:48 PM lcnc-relay: <.le_potato@> do you have oscilloscope?
07:48 PM roycroft: next is to get the mesa board to measure rpm
07:48 PM lcnc-relay: <.le_potato@> is hall works with linuxcnc?
07:48 PM roycroft: yes
07:48 PM lcnc-relay: <.le_potato@> oh
07:48 PM roycroft: i have a fluke with a frequency counter
07:49 PM roycroft: the spindle is supposed to run at about 1200rpm with a 48v input
07:49 PM lcnc-relay: <.le_potato@> thats good
07:49 PM xxcoder: is hall sensor best way to measure rpm? dunno. I didnt really have many option years ago
07:49 PM roycroft: which is 200Hz
07:49 PM lcnc-relay: <.le_potato@> then it should be accurate!
07:49 PM roycroft: and the fluke is in the mid-400s when it's at full speed
07:49 PM lcnc-relay: <.le_potato@> car manufacturers use VR sensor mostly
07:49 PM roycroft: i haven't measured output voltage from the ps
07:49 PM roycroft: it may be 52v or so
07:50 PM roycroft: those mean well psus can push a few volts more than they are rated at
07:50 PM xxcoder: would it make it go faster than 12000rpm?
07:50 PM lcnc-relay: <.le_potato@> on car with hall sensor its have 60 signal / round * 7000
07:50 PM xxcoder: higher volt
07:50 PM roycroft: absolutely
07:50 PM xxcoder: ok
07:51 PM lcnc-relay: <.le_potato@> thats 420000 signal / min
07:51 PM roycroft: when i went from 24v to 48v it went from pretty fast to jet engine sound fast
07:51 PM roycroft: it's a dc motor
07:51 PM roycroft: speed varies with voltage, not frequency
07:51 PM roycroft: the higher the voltage the faster it goes
07:52 PM lcnc-relay: <.le_potato@> you can control it with 48v pwm :3
07:53 PM roycroft: xxcoder: the potentiometer that was attached to the spindle controller (now replaced with the mesa "pot") controlled the voltage out of the board
07:53 PM roycroft: as a function of voltage in
07:54 PM xxcoder: ratio I guess
07:54 PM xxcoder: 10% in input control volt means 10% from 48v psu to spindle
07:55 PM roycroft: *chuckle*
07:55 PM lcnc-relay: <.le_potato@> you dont have any interface on the psu?
07:55 PM roycroft: mr kiss cam affair man had to resign as ceo of his tech astronomy company
07:55 PM roycroft: the question is this:
07:55 PM roycroft: did he have to resign because he got caught having an affair?
07:56 PM roycroft: or did he resign because he got caught attending a coldplay concert?
07:56 PM xxcoder: most psu have pot to adjust voltage so its dialed in. like 48v output to 48v, potato
07:56 PM roycroft: all that is irrelevant
07:57 PM roycroft: i'm not concerned with controlling the speed of the spindle
07:57 PM roycroft: that is working fine
07:57 PM roycroft: i need to monitor the speed of the spindle
07:57 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/wFj2QkRxX4BXAM7
07:57 PM roycroft: and i don't even really need to do that
07:57 PM lcnc-relay: <.le_potato@> http://gumicsonak.ddns.net/nc/index.php/s/ezy26ANeo9PSfYH
07:57 PM roycroft: if i assume it's 12000rpm, linuxcnc can set the speed to whatever i want within its range
07:57 PM roycroft: without feedback
07:57 PM lcnc-relay: <.le_potato@> my psus have lot of communication interface built in
07:58 PM roycroft: i do not care one bit about the exact voltage the psu is providing
07:58 PM roycroft: it's approximately 48v, and that is all i care about
07:58 PM lcnc-relay: <.le_potato@> you could control your spindle with pid and psu
07:58 PM roycroft: it would not benefit me in any way to know the output voltage of the psu more precisely than "approximately 48v"
07:59 PM roycroft: yes, when i get an encoder working i can add a pid routine to compensate for spindle load and the like
07:59 PM roycroft: but for what i'm going to be doing even that is not really necessary
07:59 PM xxcoder: yeah
08:00 PM lcnc-relay: <.le_potato@> btw i adjust my spindle speed simple with vfd-hz
08:00 PM lcnc-relay: <.le_potato@> with a pot
08:00 PM roycroft: yes, and we have had this discussion already
08:00 PM lcnc-relay: <.le_potato@> yup
08:00 PM roycroft: i cannot use a vfd with my spindle because my spindle is a brushed dc motor
08:01 PM lcnc-relay: <.le_potato@> i know i know
08:01 PM roycroft: on my machined with 3 phase ac spindles i control them with a vfd
08:01 PM lcnc-relay: <.le_potato@> buy an ac motor!
08:01 PM roycroft: and a potentiometer
08:01 PM roycroft: why?
08:01 PM roycroft: i have speed control on my motor
08:01 PM roycroft: soon i'll have an encoder
08:01 PM lcnc-relay: <.le_potato@> then you can buy a vfd, lol
08:02 PM xxcoder: I dont think you can even buy ac spindle that small
08:02 PM lcnc-relay: <.le_potato@> i have an 60k small spindle motor
08:02 PM lcnc-relay: <.le_potato@> want it?
08:02 PM lcnc-relay: <.le_potato@> 60k rpm
08:02 PM roycroft: yes, there actually are 52mm ac spindles, xxcoder
08:02 PM roycroft: they start at about 800w
08:02 PM xxcoder: oh interesting. was nowhere few years ago
08:02 PM roycroft: if this motor turns out to be woefully underpowered i might consider that
08:03 PM lcnc-relay: <.le_potato@> and you can control it with air!
08:03 PM roycroft: but now that it's running 2x as fast, it will probably be fine
08:03 PM roycroft: i can use smaller cutters than i could yesterday
08:05 PM xxcoder: in least that mystery of spin up being bit slow is solved
08:07 PM roycroft: yes, and iirc you said you had misplaced a psu that went with that machine
08:07 PM roycroft: so maybe you were using 48v for the spindle when you had it
08:07 PM xxcoder: yeah very likely. it was quite beefy psu
08:07 PM roycroft: i had no idea how it had been configured before
08:07 PM roycroft: it came with a 24v psu
08:08 PM roycroft: i determined immediately that 48v was more appropriate for the motors
08:08 PM xxcoder: remember I told yoy that that 2 wires from spindle board was for lost psu :D
08:08 PM roycroft: and i did not see any labels/writing on the spindle (the label was hidden by the hall sensor bracket)
08:08 PM roycroft: so i assumed that the 24v psu was for the spindle, and i supplied a 48v psu for the motion system
08:09 PM roycroft: i did not remember that
08:09 PM roycroft: but i am old and i forget a lot of stuff
08:09 PM xxcoder: yeah I dont hold it to you either. my memories is really bad too
08:09 PM roycroft: you also complained about motion control being slow, and the steppers possibly being underpowered
08:09 PM roycroft: if you used the 24v psu for them that would account for that
08:10 PM xxcoder: yeah. I bet 48v would make it a success for me if I got that rather than 24v
08:10 PM roycroft: i have motion control working, but it's not tuned/calibrated at all
08:10 PM roycroft: step 1 is make everything work
08:10 PM roycroft: step 2 is make everything work well
08:10 PM roycroft: step 3 is to happily make parts
08:11 PM roycroft: at least that's my way of doing it
08:11 PM xxcoder: indeed
08:11 PM xxcoder: sadly I never finished step 1 lol
08:11 PM xxcoder: in least, not perfectly
08:14 PM roycroft: i'm close
08:14 PM roycroft: after the encoder i still have limit switches and software e-stop, but both of those will be trivial
08:14 PM xxcoder: awesome. cant wait to see it making chips lol
08:14 PM xxcoder: its your "bill" lol
08:17 PM roycroft: i was getting some stuff from amazon and a suggestion popped up
08:17 PM roycroft: that usually annoys me
08:17 PM roycroft: but this one was for a dust boot for a 52mm spindle
08:17 PM roycroft: it was $17.95, so i added it to my order
08:18 PM roycroft: i'm still going to have issues - i cannot afford to let dust and chips fly around in my studio
08:18 PM xxcoder: I had vague plans on dust boot. it would have its own manual set z axis
08:18 PM roycroft: and it will be a while before i can build a proper enclosure for the mini-router
08:18 PM xxcoder: so spindle can go up and down and boot doesnt move with it
08:18 PM roycroft: but i have cardboard boxes and duct tape
08:19 PM roycroft: https://www.amazon.com/dp/B0CHXZ4WQP
08:19 PM roycroft: i lied
08:19 PM roycroft: it was $17.98, not $17.95
08:19 PM roycroft: but it will get me going and reduce the mess
08:20 PM xxcoder: magnetic mount
08:20 PM xxcoder: for bottom part. interesting
08:20 PM roycroft: yeah, i'll see how well that works
08:20 PM roycroft: if it does not work well i have ca glue
08:20 PM xxcoder: one gripe on magnet strength
08:20 PM xxcoder: well can always add more magnets
08:20 PM roycroft: that too
08:21 PM roycroft: the dust port is 38mm, so i'll have to find a 38mm hose or adapter
08:21 PM roycroft: i do have a little shop vac that i bought for my drill press at the old shop
08:21 PM roycroft: that should work fine for this, and it's really small, so it will be out of the way
08:21 PM xxcoder: or 3d print adoptor
08:22 PM xxcoder: its why 3d printer is amazing tool for a shop
08:22 PM roycroft: yes, i've made many dust port adapters with my 3d printer
08:22 PM xxcoder: need weird specialized adoptor? it can do it'
08:23 PM roycroft: my spindle sander has a totally bizarre dust port size that fits absolutely nothing in the universe
08:23 PM roycroft: but i made an adapter to fit a festool extractor hose
08:23 PM roycroft: same with my kreg pocket hole jig
08:23 PM roycroft: totally random size that matches nothing
08:23 PM roycroft: i don't know why those folks even put a dust extractor port on their tools
08:24 PM roycroft: do they expect everyone to just duct tape something to them?
08:26 PM roycroft: so i'm thinking i should hook up the hall sensor to some pins on the mesa board and run halscope to monitor those pins
08:26 PM roycroft: as a first step
08:28 PM xxcoder: yeah see if it even works
08:49 PM lcnc-relay: <skunkworks8841@> pcw--home: yes.
