04:12 AM Tom_L: morning
05:18 AM JT-Cave: morning
05:19 AM XXCoder: o/
07:29 AM Tom_L: at least i'm getting down to some sane numbers on the rotary now
07:35 AM JT-Cave: mine should be here today
07:36 AM Tom_L: did you read back?
07:37 AM Tom_L: prettty sure eithe [DISPLAY] or [TRAJ] were throttling the [JOINT] numbers
07:37 AM Tom_L: so i went from ~12000 down to 10 or so
07:38 AM JT-Cave: no
07:38 AM Tom_L: now i need to figure out FERROR but i think that's all in [TRAJ]
07:39 AM JT-Cave: it does get confusing
07:39 AM Tom_L: i think they use MAX_LINEAR_VELOCITY & ACCELERATION for angular in TRAJ too
07:39 AM Tom_L: which shouldn't be
07:40 AM JT-Cave: that doesn't make sense
07:40 AM Tom_L: i'm still working on that one
07:40 AM Tom_L: but those constants are not in the docs under TRAJ
07:40 AM Tom_L: for angular
07:41 AM Tom_L: unless i'm blind which also could be a possibility :)
07:43 AM JT-Cave: nothing in the docs about angular except for display
07:43 AM Tom_L: but FERROR uses numbers from TRAJ to calculate
07:44 AM Tom_L: that's in the JOINT section description
07:45 AM Tom_L: so i haven't touched any LINEAR settings and that may be where the problem is. i'll find out later today
07:48 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/new_mill_A.ini
07:49 AM Tom_L: that was the last test yesterday
07:49 AM Tom_L: and it seems to be getting better
07:49 AM Tom_L: numbers might be a little low now
08:10 AM JT-Cave: https://www.omc-stepperonline.com/closed-loop-stepper-driver/closed-loop-stepper-driver-0-70a-24-48vdc-for-nema-17-23-24-stepper-motor-cl57t.html
08:11 AM Tom_L: later..
10:25 AM roycroft: jt-cave: did you get your label machine figured out?
10:34 AM JT-Shop: yes
10:40 AM aaroncnc: i wish there was an open source firmware or hack from the dymo/brother small label printers. I hate the insane amount of padding that cant be adjusted.
10:41 AM roycroft: great
10:41 AM roycroft: i don't remember setting mine to do half cuts, but it does
10:41 AM JT-Shop: that's what I really like about the Epsom it only wastes 8mm for a series of labels
10:41 AM roycroft: perhaps it came that way, or perhaps i set it up and forgot
10:42 AM JT-Shop: just have to use multiple labels
10:42 AM roycroft: yes, i'll make back my investment in the printer in no time in saved consumables
10:42 AM JT-Shop: shift mix-len
10:42 AM roycroft: even when printing individual labels, the feature where it can reverse the tape after cutting saves a lot
10:44 AM roycroft: i don't know what kind of labels you make aaroncnc, but this new epson label printer that jt and i both bought works really well, and can print with margins as small as 4mm on each side
10:44 AM roycroft: i have several p-touch printers, and there's just no way to conserve on margin waste
10:45 AM roycroft: and i don't think you'll find any hack to fix that - the issue is that the cutter is fairly far away from the printhead, and you'll never be able to waste less than that distance
10:45 AM aaroncnc: my current lable maker is a letraTag and it has about 20mm padding each side.
10:45 AM roycroft: the epson has a feature where it cuts off a label then rewinds the tape
10:46 AM aaroncnc: that sounds nice what is the model?
10:46 AM skunkworks: we just bought a therman transfer printer for printing rfid badges.. Seems to work good.
10:46 AM aaroncnc: I always have to manualy cut all my labels after making them as they are stupid long.
10:46 AM roycroft: lw-px700
10:46 AM skunkworks: thermal
10:47 AM roycroft: i got it so that i could print directly on shrink tubing
10:47 AM roycroft: but i'll be using it for standard labels as well, as i start using up all my ptouch cartridges
10:48 AM aaroncnc: most label makers can print onto heatshrink, they just require you to use the thermal reactive tubing and tricking the unit into thinking it has normal paper
10:48 AM roycroft: and i'll use it right away for standard labels if i'm labeling things like patch panels or multiple ethernet ports on a server, as the epson is designed specifically to do that kind of stuff
10:50 AM roycroft: well perhaps i'm not very clever, but there are no shrink tubing cartridges made for the p-touch printers i have, and i don't know how to shove shrink tubing and an ink ribbon into a standard cartridge
10:50 AM aaroncnc: you could just buy a cartridge that is the same width as your current and just respool it into an empty cartridge.
10:51 AM roycroft: that doesn't seem like an easy thing to do
10:51 AM roycroft: but it's ok
10:52 AM roycroft: the epson is designed specifically for industrial label printing, with features like flag labels, sequence labels, patch panel labels, etc.
10:52 AM roycroft: it also has a half cut feature, where on a strip of labels it will cut through the label and not the backing
10:52 AM roycroft: with shrink tubing it cuts most of the way through, but still keeps the tubing together in one piece
10:52 AM roycroft: the individual labels can be pulled off very cleanly
10:53 AM roycroft: i'll keep using the p-touch machines for office labeling, but the epson is now my standard label printer for anything network/electronics related, with the exception of when i need wrap-around labels
10:54 AM aaroncnc: roycroft, https://www.youtube.com/watch?v=8OQDrtP9Tx4
10:54 AM roycroft: my panduit labeler, which i've had for many years, and for which i have pretty much a lifetime supply of the larger size wrap-around labels, is still fine for that stuff
10:55 AM roycroft: i believe it can be done, aaroncnc, but i'm sure it's at the very least a hassle to do that, and i already have a nice shrink tubing printer
10:57 AM aaroncnc: roycroft, that label maker looks awesome but the price is just a bit high for me. I am evry frugal person. i try to sqeeze every last drop of value out of a thing i own. sometimes at unreasonable time expenses.
10:58 AM roycroft: i got a 20% discount on mine, and i ordered the basic printer, but they sent me the deluxe version for some reason, so i'm pretty happy
10:58 AM roycroft: <$100 for the thing
10:59 AM roycroft: and as i said, the rewind feature is great
10:59 AM roycroft: i'll recoup my investment in the printer in saved consumable cost fairly quickly
10:59 AM roycroft: frugal does not mean buying the cheapest thing possible
11:00 AM roycroft: it's about long-term cost of ownership and operation
11:01 AM roycroft: the epson printers also come with a lifetime warranty
11:02 AM JT-Shop: and great support
11:04 AM JT-Shop: panel is done and looks good time for lunch minute
11:07 AM roycroft: i'm not here to promote epson label printers, but you were complaining about the padding waste with the brothers, and i had the same problem, and found the epson printer as the solution
11:07 AM roycroft: there's no way to fix a p-touch labeler to eliminate that padding, as the pt-touch feed motor does not reverse
11:12 AM aaroncnc: the issue at heart it for my my use is only personal not professional. well i do use my label maker every week. i dont think the cost saving would even out in any reasonable amount of time.
11:19 AM aaroncnc: just a few months ago i borrowed some clear uv set top coat from my wife to protect some labels that were getting worn out from cleaning. that stuff is neat. still cant hit it with brake clean but some soapy water is just fine.
11:25 AM roycroft: and that's a calculus only you can make for your situation
11:26 AM JT-Shop: dividing head is here
11:26 AM roycroft: for me, with a waste of at least 50%, it takes about 6-7 tape cartridges before i'm money ahead on the new printer
11:27 AM roycroft: and for shrink tubing, the waste with a brother would be closer to 75%, as i tend to print only a couple or three characters on a shrink tube label
11:28 AM roycroft: if it takes you five years to go through a half dozen cartridges then investing in a new printer might not make sense
11:28 AM roycroft: if you go through that many in a year, it makes a lot more sense
11:28 AM roycroft: if you go through that many in a month (i don't) then you're a fool not to get the new printer
11:30 AM roycroft: and i'm not even considering the cost of time to deal with the old printer - for a hobbiest, time is usually not an important factor, so excluding it from this equation is apt
11:43 AM JT-Shop: for me when Kroy went out of business and I ran out of small shrink tubing it was time for a new one
11:46 AM aaroncnc: i am looking at the LW-PX400 how is it more money than the 700 and has less parts? is adding BT that expensive? I do like the idea of using my phone and not the keypad on the device.
11:46 AM aaroncnc: https://labelworks.epson.com/printers/lw-px400/epson-labelworks-px-lw-px400-printer.html
11:49 AM roycroft: i don't know why it costs more
11:50 AM roycroft: i wanted a printer that did not have to rely on an app to operate it, because apps are not always kept up to date
11:50 AM roycroft: that's been a problem with my brothers - i have a half dozen or so of them now
11:50 AM roycroft: and they all work perfectly
11:50 AM CloudEvil: Or google fucking cloud fucking print.
11:51 AM roycroft: but only one is currently supported by the brother software, and a lot of the features on those printers require the app
11:51 AM aaroncnc: roycroft, thats true and you never know if they force it to phone home to work. i hate that so much when things need the internet to work even tho there is no good reason for it
11:51 AM roycroft: i like the epson because virtually everything i would ever want to do with it can be done on the printer keypad
11:51 AM roycroft: so far the only thing it can't do is print a phase symbol
11:52 AM roycroft: and it can kind of do that even - there are two common phase symbols in the us - a tilde and a modified greek phi
11:52 AM roycroft: the tilde phase symbol is on the printer
11:52 AM roycroft: and the greek alphabet is as well, so i could always use an actual phi
11:52 AM aaroncnc: ϕ
11:52 AM roycroft: but if i want the modified phi phase symbol i have to download it to the printer, which requires the app
11:52 AM roycroft: yes, similar to that
11:53 AM aaroncnc: but once you use the app it would save it in memory so one and done?
11:53 AM roycroft: the one commonly used for electrical diagrams/labels has a diagonal line instead of a vertical one
11:53 AM roycroft: yes, if i download the symbol once it's there as long as i don't delete it
11:53 AM roycroft: and epson have a feature request in to add that symbol to the built-in ones
12:10 PM roycroft: i might want to download a logo to the printer as well
12:10 PM roycroft: the mac version of the epson app is pretty much useless, but i was able to install the windows version in a vm, and i can download symbols from that
12:11 PM roycroft: i'll probably keep a p-touch labeler on my desk forever, and know that every few years i'll have to get a new one so that the app will work, even though the old one still functions stand-alone
12:12 PM roycroft: perhaps i'll start a p-touch museum some day :)
12:23 PM aaroncnc: ohh the fun of adding pid into my config tool. 9 new inputs. going to be hard making this not look messy with each item having 17 inputs.....
01:01 PM Tom_L: JT-Shop, that came early
01:25 PM aaroncnc: so i am looking at a sample config from scotta and see this "loadrt PIDcontroller names=PID-bed,PID-ext0" so i went to look it up in the docs but this is what i found https://linuxcnc.org/docs/2.6/html/man/man9/pid.9.html are they the same?
01:27 PM Tom_L: doesn't sound like it
01:33 PM aaroncnc: okay, so in a different repo has a custom hal component.
02:07 PM JT-Shop: Tom_L, what's that?
02:19 PM Tom_L: indexer
02:20 PM JT-Shop: came FedEx so sometimes they are early and sometimes not
02:20 PM JT-Shop: looks well packed and covered with earl
02:21 PM Tom_L: yes
02:22 PM CaptHindsight[m]: aaroncnc: the UV cured coating is not soluble in the solvents you tried, it becomes a crosslinked polymer after cure, it will take acids to break it down or long term UV exposure
02:22 PM CaptHindsight[m]: that actually an interesting product idea, a flexible UV cured topcoat for inexpensive labels
02:23 PM aaroncnc: CaptHindsight[m], i used to use clear tpe in areas i knew it would get alot of use but after a year the tape gets messed up.
02:23 PM aaroncnc: crossing my fingers this holds up better
02:23 PM CaptHindsight[m]: UV nail polish?
02:24 PM aaroncnc: yea using UV nail polish clear top coat to protect my labels.
02:24 PM JT-Shop: that's why I bought a Kroy back then it laminates a clear cover over the label
02:24 PM CaptHindsight[m]: it just won't flex much
02:25 PM aaroncnc: most things i add labels to dont flex or if they do i have bigger problems
02:31 PM CaptHindsight[m]: safety first https://youtu.be/_uhQl6krCaM?t=26
03:42 PM JT-Shop: hmm my dividing head has quite a bit of backlash or won't move take your pick
04:18 PM JT-Shop: coolant tank on the 308 is clean and filled up, now to clean the pump and lines out
05:07 PM roycroft: when i worked in telco central offices we had to plaster labels all over the place on our equipment racks and equipment
05:07 PM roycroft: the offically-approved product by then uswest for protecting the labels was mod-podge
05:08 PM roycroft: i.e. "decopage paste"
05:08 PM roycroft: it actually worked quite well in that environment
05:09 PM roycroft: mod-podge is mostly polyvinyl acetate
05:11 PM Tom_L: crap, somebody posted a line to have halmeter start up with screen locations now i can't find it
05:17 PM JT-Shop: my Current TPD was 1030 - 1103... we have passed that and that was the second time it was pushed back
05:17 PM JT-Shop: TPD Tentative Production Date
05:29 PM CloudEvil_ is now known as CloudEvil
05:32 PM Tom_L: no parts
05:37 PM JT-Shop: they have to go through panama and to the gulf to get unloaded by rednecks
05:37 PM JT-Shop: I can understand no truckers wanting to drive in Commiformia too many restrictions
05:38 PM JT-Shop: and then we end up paying extra to get them unloaded... sure is screwed up now
05:44 PM CloudEvil: https://www.youtube.com/watch?v=ERqikbfoLnw I recommend.
05:44 PM CloudEvil: How to Clear the Ports of Los Angeles/Long Beach in Five Steps | What's Going on With Shipping - more generally the whole channel.
05:45 PM CloudEvil: In short, there are several bottlenecks, and it's complicated, and nobodies trying to sensibly fix it because all the regulations got junked in the 80s.
05:45 PM CloudEvil: And nobody is responsible.
05:45 PM JT-Shop: how to clear the ports of los angeles send the ships to washington
05:48 PM roguish[m]: Port of Oakland has been trying to get ships.....
05:51 PM CloudEvil: Problem is scale. Around 10M containers/year in LA. Smaller ports are tiny in comparison
05:52 PM * JT-Shop listens to some Aerosmith before going inside
05:55 PM JT-Shop: pizza time here
05:57 PM Tom_L: ooo that sounds good
06:24 PM unterhaus: JT-Shop, can you read solidworks files?
06:27 PM Tom_L: unterhaus, he has solidworks
06:27 PM Tom_L: what version?
06:27 PM unterhaus: 2021
06:27 PM Tom_L: no
06:27 PM Tom_L: best to use iges
06:27 PM Tom_L: iirc his is in the teens
06:27 PM Tom_L: 14?
06:27 PM Tom_L: i forget
06:27 PM unterhaus: yeah, they are a pain
06:28 PM Tom_L: maybe i just struck gold
06:28 PM unterhaus: plus the version they give me for free is the student version, so opening is a problem with commercial version anyway
06:28 PM Tom_L: i found one line i forgot to uncomment when i set up the rotary axis in hal
06:28 PM Tom_L: it was the feedback :)
06:28 PM Tom_L: gonna test in a bit
06:28 PM Tom_L: i'd been focusing on the ini all this time
07:37 PM XXCoder: lol myfordboy does a restore video
07:37 PM XXCoder: surpised me
08:08 PM Tom_L: skunkworks, video to come...
08:10 PM solarwind: public service announcement: This gojo supro max is the best hand cleaner I've ever used: https://www.amazon.ca/GOJO-SUPRO-MAX-Hand-Cleaner/dp/B019666XF4
08:11 PM solarwind: It's obscenely expensive though
08:11 PM solarwind: It's on a whole different level compared to the regular gojo orange and similar. It's far superior
08:13 PM * Tom_L is content to have dirty hands for that price
08:14 PM solarwind: I discovered it while helping a friend install an air compressor at a dealership
08:15 PM solarwind: They had that in a dispenser in the washroom. I almost didn't use it because I expected it to feel like every other abrasive hand cleaner
08:15 PM solarwind: But it was absolute bliss
08:20 PM Tom_L: skunkworks, CaptHindsight[m] https://www.youtube.com/watch?v=YUAqIt_YRQQ
08:22 PM XXCoder: threadmilling?
08:22 PM Tom_L: no
08:22 PM Tom_L: rotary cutter path
08:22 PM XXCoder: cool :)
08:22 PM Tom_L: and canned cycle test
08:23 PM XXCoder: cant wait to see it cut chips
08:23 PM Tom_L: new post for A axis on my cad cam too
08:24 PM Tom_L: still need to wire up a home switch for it
08:28 PM Tom_L: the x axis follows the head as it accelerates/decelerates just like G33 would on a spindle
08:43 PM roycroft: i've been using boraxo powdered hand soap for as long as i can remember
08:43 PM roycroft: at least 45 years
08:44 PM roycroft: i have a dispenser mounted on the wall next to my sink in the shop
08:55 PM Tom_L: i'm rather pleased my cad cam supports 4 and maybe 5 axis
08:55 PM Tom_L: not just indexing
08:56 PM Tom_L: i won't be using 5 though
08:56 PM * roycroft needs to make pizza
08:57 PM Tom_L: you should have gone to JT's tonight
08:57 PM Tom_L: he also had pizza
09:13 PM roycroft: he made pizza last weekend when i made pizza
09:13 PM roycroft: and i made mine on saturday, because i had a meeting on friday
09:13 PM roycroft: hmm
09:13 PM roycroft: or maybe he was making it on friday
09:14 PM roycroft: anyway, it sounds like it's becoming a weekly thing for him now
