02:21 AM Rhine_Labs: How do you like that little reflow oven..
02:21 AM TurBoss: ...
02:22 AM Rhine_Labs: this was my reflow oven sadly to make it thru covid lock downs had to sell. https://youtu.be/lT2MkcTNlqQ
02:22 AM TurBoss: its small yes :D
02:22 AM TurBoss: i see lol
02:22 AM TurBoss: sorry
02:22 AM TurBoss: I mean
02:22 AM TurBoss: its huge
02:23 AM Rhine_Labs: Yea, at one time was a money maker..
02:24 AM TurBoss: there is a project arround for your NES
02:24 AM Rhine_Labs: I regret selling it now.. was on track to get my piot medical back.
02:24 AM TurBoss: a pcb clone, have you seen?
02:24 AM Rhine_Labs: Yea, built a few opentendos
02:25 AM TurBoss: awesome
02:25 AM TurBoss: i just saw videos
02:25 AM Rhine_Labs: Yea, not really worth it in my opinion,,
02:26 AM Rhine_Labs: I did it a few for a customer that really wanted some.
02:27 AM Rhine_Labs: JLC PCB best price on boards.
02:27 AM TurBoss: Rhine_Labs: in your opinion: it is much hard make a mesa board compatible with icestudio?
02:27 AM TurBoss: https://icestudio.io/
02:27 AM TurBoss: the ide I showed before
02:27 AM Rhine_Labs: I have no clue
02:29 AM TurBoss: I have a project in mind , a node editor for hal files
02:29 AM TurBoss: only did a draft
02:30 AM TurBoss: https://github.com/TurBoss/TurBoHal
02:30 AM TurBoss: :)
02:31 AM Rhine_Labs: Never really learned to code..
02:31 AM Rhine_Labs: I can do basic stiff old stuff ..
02:31 AM Rhine_Labs: stuff..
02:32 AM TurBoss: but like the idea?
02:32 AM Rhine_Labs: back in the late 90's early 2k's machine code for pic's 16C
02:48 AM Rhine_Labs: trubox would need to know more on what it does.
02:48 AM Rhine_Labs: TruBoss
02:48 AM Rhine_Labs: Cannot typ with $it tonight.
02:50 AM TurBoss: it should write hal files based on nodes drawn in grid and linked togueder

11:19 AM roycroft: this is one reason i like mcmaster-carr so much
11:19 AM roycroft: i received an order from them on saturday
11:20 AM roycroft: one line item was missing from the order
11:20 AM roycroft: i emailed them less than 10 minutes ago about it
11:20 AM roycroft: i just received an apology email with a tracking number for the shipment of the missing items
11:25 AM JT-Shop: yeah they have great service
11:26 AM roycroft: they cost a little more than some vendors, but they keep almost everything in stock all the time, ship immediately, and have outstanding customer service
11:26 AM roycroft: not to mention the cad drawings of about 98% of their products
12:06 PM Eric_ is now known as unterhausen
12:07 PM unterhausen: I don't think McMaster ever missed a line item for me. They sent me something extra once. They didn't want it back, but because it cost $500 I wasn't going to throw it away, but I didn't need it
12:07 PM roycroft: this is the first time i remember something from them being missing
12:08 PM unterhausen: I did recently think of a use for it, but I would have needed another one
12:09 PM unterhausen: I guilted them into sending me a shipping label
12:09 PM roycroft: i've had other shipments that did not go out right away, and when i contacted them to ask when they think they would ship, they overnighted the items as a new shipment, and told me to refuse the original shipment whenever it arrived, or keep it if it got delivered anyway
12:20 PM unterhausen: I worked pretty hard getting all the brush out to the street yesterday not thinking about how today is a holiday
12:21 PM roycroft: it's a bank holiday but mail will still be delivered
12:25 PM XXCoder: bank holiday today?
12:25 PM roycroft: yes
12:25 PM roycroft: indigenous people's day
12:27 PM XXCoder: wow glad I found out before 3 hour drive
12:27 PM XXCoder: tomorrow it is then
12:29 PM roycroft: your bank is 3 hours away?
12:32 PM XXCoder: yeah i opened account there ages ago
12:33 PM XXCoder: but since then moved here. however cu have shared bank stuff
12:33 PM XXCoder: its extremely rare I need to go to specific cu
12:38 PM XXCoder: well roy thanks for saving my time heh
12:43 PM CaptHindsight[m]: https://www.newsweek.com/columbus-day-2021-us-post-office-opening-hours-delivery-information-1636855
12:43 PM CaptHindsight[m]: they could just say in the headline but nnaaaaahhhhh
12:44 PM CaptHindsight[m]: spoiler "The U.S. Postal Service (USPS) is closed on Columbus Day and USPS branches won't be open on the day."
12:44 PM XXCoder: capt it doesnt say on my cu website either, i had to call them to find out if they are open or not
12:45 PM CaptHindsight[m]: business hours went to shit during the lockdown
12:46 PM CaptHindsight[m]: online hours rarely match a businesses actual, at least around here
12:57 PM roycroft: interesting, as i got an email from the usps this morning saying a parcel is out for delivery today
12:58 PM Tom_L: lies
12:58 PM roycroft: perhaps
01:12 PM -!- #linuxcnc mode set to +v by ChanServ
01:18 PM roycroft: my parcel was just delivered
01:37 PM CaptHindsight[m]: fake news
01:41 PM solarwind: Someone mentioned that preparation is the most important thing before painting a concrete floor. Might have been you, CaptHindsight[m]
01:41 PM solarwind: What kind of preparation? Do I need to surface grind to reveal fresh concrete?
01:42 PM solarwind: Or just degrease with an industrial degreaser?
01:42 PM CaptHindsight[m]: going with an alkyd or epoxy?
01:42 PM solarwind: Cheapest option, not epoxy
01:43 PM CaptHindsight[m]: the degrease and fully dry
01:45 PM CaptHindsight[m]: moisture and oil base is not good
01:46 PM CaptHindsight[m]: add Japan drier to the oil base
01:47 PM roycroft: is there sealer on the floor?
01:47 PM roycroft: if so, you really need to media blast it to remove the sealer
01:48 PM roycroft: if not, then clean and degrease thorougly, and then apply a muriatic acid wash
01:49 PM solarwind: I don't think there's a sealer
01:49 PM solarwind: How can I tell?
01:49 PM roycroft: if you pour water on it, does it bead up?
01:49 PM solarwind: Definitely not
01:49 PM roycroft: then there is likely no sealer
01:50 PM roycroft: in which case, thorough cleaning and then the muriatic acid wash are in order
01:50 PM solarwind: Ok will do, thanks guys!
01:50 PM roycroft: if you don't like working with concentrated hcl, then skip that and lightly surface grind
01:50 PM solarwind: Oh I don't mind at all
01:50 PM roycroft: but if you're careful and use proper ppe the acid washing process should go fine
01:51 PM solarwind: HCl is not nearly as bad a sulfuric acid and such
01:51 PM roycroft: i'm assuming you want to do this floor painting once and have it last decades
01:51 PM CaptHindsight[m]: you can skip the acid with an alkyd
01:51 PM solarwind: A few years is sufficient
01:51 PM solarwind: It's a rental
01:52 PM CaptHindsight[m]: you have to fully remove the acid before coating
01:52 PM roycroft: yes
01:52 PM roycroft: but that can be done with a pressure washer
01:52 PM CaptHindsight[m]: so it's lots of pressure washing
01:52 PM roycroft: the real problem with the acid wash is that anything metal in the building will corrode if it's not protected from the acid fumes
01:52 PM CaptHindsight[m]: and more timeto dry
01:53 PM roycroft: structural beams, etc. are not a big deal
01:53 PM roycroft: milling machines and the like a bit more of a problem
01:53 PM CaptHindsight[m]: if the alkyd gets dirty, you can clean it up with degreaser and a solvent wash
01:53 PM roycroft: but the epoxy will get a better 'bite' if you acid wash
01:54 PM CaptHindsight[m]: he's not using epoxy
01:54 PM roycroft: an alkyd floor paint will not last as long as epoxy
01:54 PM roycroft: but it will be easier to apply
01:54 PM roycroft: so if it's really only for a few years, that might be the way to go
01:54 PM CaptHindsight[m]: here we go..... hasta
02:07 PM solarwind: I have lots of ventilation. I'm going to do a full oil spray with very thick oil on the machine tools before doing any of this
02:08 PM solarwind: I'll have blowers sucking fresh air from outside -> machine tools -> blower -> other side
02:08 PM solarwind: With the acid on the high pressure side of the blower
02:59 PM Tom_L: roycroft, what goodies did you get in the mail?
03:00 PM roycroft: some fuses and a label cartridge
03:00 PM Tom_L: ahh
03:00 PM Tom_L: starting to get that figured out?
03:01 PM roycroft: get what figured out?
03:01 PM Tom_L: your control for the mill
03:01 PM roycroft: oh, i'm not working on that right now
03:01 PM roycroft: the fuses are for the cnc router
03:02 PM roycroft: i'm still thinking about the mill
03:02 PM roycroft: i have access to it now, which is nice
03:02 PM roycroft: but i have some concerns about going directly to the spindle from the motor, and bypassing the transmission
03:02 PM roycroft: even with the bigger motor and the vfd, i'm not sure i can run it slowly enough and still have decent torque
03:03 PM roycroft: i was about ready to order the timing gears, but then i started having second thoughts about it
03:04 PM roycroft: if i can only run it at 500rpm or so and up, that limits the work i can do severely
03:05 PM roycroft: i need to get it working again soon, so i have to get this sorted very soon
03:45 PM roycroft: so i did finally get around to trying the label machine software, and it does not work at all for me on a mac
03:45 PM roycroft: there is no printer driver for the current models of their label printers
03:45 PM roycroft: it's windows or nothing
03:46 PM roycroft: and epson just confirmed that, but also submitted a request to add mac os support for my printer
03:46 PM roycroft: they also told me that if all i need to do is install some custom symbols on the printer, i could send it in to them and they would install them
03:46 PM roycroft: i'll install their software on a windows vm before i would do that, but it's nice that they offered
04:24 PM CaptHindsight[m]: summer of drought, and rain every day now that the temp is pleasant (with tornadoes today)
05:15 PM _unreal_: sooo damn cool. I just pulled out the smallest linear stepper I've ever seen
05:15 PM _unreal_: its SOOOOOOO small
08:03 PM cradek_ is now known as cradek
08:49 PM xzyzz: hi friends. i have a 7i92 and 7i76 but can't seem to get a signal to the latter so i suspect i might have the wrong bit file loaded. can anyone tell me if i should be using the 7i92_7i76x1dpl.bit, or 7i92_7i76x1D.bit (my 7i76 is not a D model), or something else?
08:50 PM XXCoder: hey, hopefully someone can answer soonish :)
08:51 PM Tom_L: that's a pcw-home or JT-Shop question
08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/mount/Rotary_mount3.jpg
08:52 PM CloudEvil: Unabstract sculpture.
08:52 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/mount/Rotary_mount2.jpg
08:53 PM XXCoder: center bore, bolt it on, do outside parameters, do corner cuts, then drll holes. bolt corners, then do center bolt
08:53 PM Tom_L: gonna use standoffs instead of the previous design
08:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/rotary/mount/Rotary_mount.JPG
08:53 PM XXCoder: actually better to do 3 bolts first then corners lol am i anywhere close to your planned operations?
08:54 PM CloudEvil: Did little recesses recently like that with bandsaw
08:54 PM CloudEvil: (on a little jig, not freehand)
08:55 PM CloudEvil: (obvisly just 45 degree corner cuts with flat underlying)
08:57 PM Tom_L: 7 bolt holes, center then corners
08:58 PM XXCoder: part held in jaws or?
08:58 PM Tom_L: probably
08:58 PM XXCoder: corners might be done seperately by just bolting it on?
08:59 PM XXCoder: unless can just use small section to hold on into.'
08:59 PM Tom_L: one position
08:59 PM Tom_L: i'll likely use softjaws in case the stepper holes get into the jaws a bit
09:00 PM XXCoder: probably do a dryrun to see if it will be fine
09:00 PM Tom_L: pfft :)
09:28 PM roycroft: yay
09:28 PM roycroft: i was just able to schedule an appointment for my booster jab
09:29 PM XXCoder: nice
09:29 PM roycroft: it's a bad time for me, but i'll make it work
09:34 PM xzyzz: solved it. the 7i92_7i76x1D.bit file seems to work. turns out i had an ID10T error that needed sorting first.
09:35 PM xzyzz: :)
09:36 PM XXCoder: :)
10:25 PM Tom_L: plane hit ups truck in SanDiego neighborhood
10:30 PM Nick001: I'm reintalling new nema 42 motors with a 7i76 card and I noticed encoder capability. If i install an encoder on the motor, will it operate as a closed loop and correct for lost steps during movement?
