Old CNCs, clever video editing, humor, perfection! Keep it up man!
Thanks!
I'll program that on the machine in like 1/2 hr using g71, g72, & g75 and it certainly won't be 300 lines of code!
Great vid!
Also I can reprogram depths of cuts on the fly by changing variables in the can cycles.
Which means I can prove out the program in 5 minutes flat.
Been doing this for 35 years now
That was fantastic!!! Loved the narrative -- these videos just keep getting better!
Thanks! That really means a lot.
Guys, you grew so large, you’ve done many epic things, help this man grow too, such a potential, I can’t believe he has only 150K, this content deserves couple of millions at least
@SH keep up keeping up, man, you doing amazing! It’s very inspiring, coz I’m doing stuff too, and your videos got to me at right time! Thank you!
Dude, you've become the William Gibson of RUclips maker channels! I love the cyberpunk nearby alternate reality and the overtones of Max Headroom and Lance Boyle of Megarace
The possibilities are literally endless now
Such an accurate comment! Spot on
Sean, your workshop is looking amazing (from what I could glimpse) - I'd love to see more of the space when you are ready!
I should get a mobile livestream working and do a Q&A workshop tour!
I used to own a MS Sl-5a. These are incredibly well made machines and the fanuc controlls (I had a 10t) were way ahead of its age. Keep this machine, fill the lubrication system every once in a while and it will run forever with really great precision and stability!
Loved the cyberpunked session!
Love to hear it! I want to keep it going for as long as I can on the original hardware. We’ll see how that goes. Thanks!
@@SeanHodgins Bubble memory?
@@jsihavealotofplaylists I was using dnc until it froze at 100k lines on my mill. I think lathes have smaller programs when 2axis and dnc should be just fine. Off topic but you mentioned memory and I had to add to it.
1st CNC I ever worked was a MS TL-5 , saw it installed as a 2nd yr apprentice (17), it's still in use now, & I'm 57, that's 40 yrs of constant use in the same shop !
Awesome machines.
Glad to see you survived the persistance of vision Christmas tree of death project.
This is another great video. And that lathe is a beast.
This version of me did at least!
Those are still pretty viable machines. Those are "yellow cap" Fanuc brushed DC servos. It should use a +/- 10V analog signal instead of step and direction. The 6T is a good control that can do anything a 2 axis lathe should ever need to do. The offsets are kind weird as I recall, they don't really have a work offset, but there are ways around that. I had a 1980 Mazak Slant Turn 15 with a Fanuc 6T control. It was a solid machine.
Still learning more about it every day! It uses a grid system with G50. I'm not doing that though. I'm just basing all of the tool offsets from tool 1. So tool 1 is "0, 0" and all the other offsets are the difference from there. So I will call, say tool 2, with T0200, so that it switches tools, then T0202 to load the offset and move to that location.
@@SeanHodgins That works. You may find it more convenient to set your tool Z offset from a fixed location (face of the collet nose or whatever), then set the G50 from the same location. That way you don't have to reset the tools for every job, you just have to set the G50, which as I recall is done inside the program.
There were some other weird things. Using constant surface speed the RPMs would go wonky during a tool change. That was so annoying I pretty much gave up using it. Also I had to add a couple relays to trick the PLC so I could do bar pulling. Without those relays the control would not allow a feed move with an RPM of zero or with the chuck open.
On my machine, I tool index and set my Z offsets from Z G30 2nd reference return pos position. There are a lot of ways to do this, but for me, this is the cleanest way to work with a machine that only has offset for wear(there is no geometry page). My format is G30 U0 W0; Txx00; G50 X0 Z0; then set G50 Xx Zx (offset values) from this location. This is, of course, if you have the optional 2nd ref return on the machine. My machine moves the slides the instant it pickups the values in the wear register at the TxxXX line. Can you give you a heart attack if the values are too large or might over-travel if done at home pos. It's good practice to limit your offsets to about .010
Was about to say they are dc M series servos. Beat me to it man.
There are a couple of ways to do tool offsets on a 6T machine... the most modern way is if your machine has the “custom macro B” option. If you have this option you can write a little code to made it behave like a modern machine with geometry offsets.
My machine doesn’t have this option, it’s slightly older with the DC spindle and the brushed servos. You have a very desirable old piece of iron!
I have a video on my channel describing how to program with G50 offsets if you want to see another way to do it.
6:48 your lighting and narration.
And this bit of closing black bars, but made real.
So unique and creative!
Awesome man!
That's a mad project mate! I wish you the best of luck, the old ladies were meant to last!
She fired right up!
Perfection! A real art piece
Thank you!
I came here super early and the $1 spinners were still available, but shipping to Barcelona was $10... So not buying the spinner but buying one of those Super Thanks. I prefer you to keep the money and not some postal service
Wow thank you! Shipping costs are the bane of my existence.
Worked on those machines when they were state of the art. I go back to the nc machines that used vacuum tubes. Our Mori’s were the first cnc machines with a crt. Brings back good memories. Going to retire next year with 47 years in the machining business.
about 5:30 i used to work on a MAHO1000 and in order to get all lines of program sent to the cnc you need EOT in the end of the programm which is " alt + 4 " ,otherwise i always get 5 lines missing, and that should solve the problem of missing lines in the end it would be nice if you reply with a feed back :3
And again, learning incredibly useful information from the comments section. Thank you!
@@SeanHodgins you're welcome glad i could help :D
As an individual who has been running machines like this since the 80's, the punch tape does not necessarily run the machine. It was mainly storage media because the machine has internal storage. The only time we ever ran machines off the tape was if the program exceeded the storage of the machine. Machines that were just NC, required the tape to run. We typically wrote programs longhand on a programming sheet then, used a Flexowriter typewriter to create the punched tape. You could splice the tapes with edits or make edits at the machine then connect a tape punch to the RS-232 to punch a new tape. Also, programming is simplified by the use of canned cycles that allowed you to rough and finish by defining the finished shape and using a 2-line code to establish depth of cut and stock allowances. CAD\CAM software was available but, the cost of the software was almost as much as the machine. Back in those days, a machine like this cost about 3x the average cost of a house. Those old Mori-Seiki lathes were indestructible along with the Fanuc controls. Nice score!
Really cool, thanks for the history! I’m not sure how to use the canned cycles yet. I would love to find a tape punching machine just for fun.
When I started an industrial machine shop program they had recently purchased a CNC mill, and by the time it was delivered and installed, it was obsolete. None of us had CNC training and I was one of the last few people to complete the 2 year course before they closed the machine shop program.
Exponential sales, brilliant! 😄
It sort of ensures I won't need to make them forever!
This is very exciting. I'm no machinist, but the beauty looks beastly enough to cut more than a little brass. Have you tried programming the arm to do the loading and starting on the machine?
Yeah I don’t think it even knows the brass is there.
Man buys industrial robot just to have assistant camera operator.
Heh, yes, "buys".. definitely not a stray robot that just showed up one day and won't leave...
Man is now part of said robot's plan for global domination.
The machine appears to be in great condition. The electrical cabinet looks really clean (perhaps you gave it some TLC after you acquired it?). These Mori Seiki SL1 ~SL8 series lathes were real workhorses here in Houston, Texas in the oil tool industry in the 80s and well into the 90s. There are still many machine shop owners here holding on to these for "sentimental value" (the very first CNC machine they bought etc.). In case you do not have yet, here are some manuals you may want for future reference. Fanuc 6T-B Maintenance Manual B52245E, DC Servo M-Series Maintenance Manual B53265E, AC Spindle Maintenance Manual B53425E. Great video!
Thank you! I actually didn't clean any of the electrical stuff. Some of the seals are crumbling to pieces, but everything looks well taken care of. Thanks for the manual references. I have the Fanuc 6T-B one I think, but missing the others.
I'm from Brazil and I watch your videos. I loved your channel. Fantastic!!! Keep posting videos with this machine
Sweet machine, thanks for sharing 👍👍
No problem, thanks for watching!
Have no idea what a single piece of this equipment is or does, but the editing in this video is just great
I like to think you gained a little bit of knowledge, no? Lol
Just blown away when watching the end ! Good story and excellent acting. ❤
Whos acting? 😆 Thank you!
Great video! Wow, 3:34 and other PCBs is like poetry (I am more electronic than mechanic) :) Good luck with this machine!
They are really cool. Thank you!
I love what you`r doing, love your creativity and sence of humor. I wish you will produce more ! grettings form Poland Europe !
I definitely will, Thanks! Hello to all my viewers from Poland!
Hi Sean nice looking machine ! If it is a 1985 or later machine I might have done the original installation, assuming it was sold new in canada .
The servo drives are +/-10vdc analog
Not stepper .if you look on the drive you might see a DAC chip .
If you need a new rabbit hole to fall into
Do some research on bubble memory.
That was the original memory used
There once was a thriving business of selling unauthorized replace memory boards because bubble was very expensive and not so reliable
Oh if you have not done so already its
Extremely important to check the condition and length of the servo motor brushes .there is a section in the manual explaining how
Thats amazing, it is a 1985 I believe! Great! Ill check it out. I have all the documentation for the machine. I might even have a receipt if the brushes were ever replaced.
One of our oldest machines (an Okuma MC60-VA) uses bubble memory. Not very big at all, but then there's the floppy disk for a backup, and program storage.
The real answer is 'Why not?'. Yes. Yes it is.
Thats is typically my answer to these types of things.
@@SeanHodgins It's the only real answer
Normal people: Place logo and animate scale. Sean: Programs the "the assistant" robot arm holding a physical cut out and films a timelapse instead. 😂
I can watch hours of this stuff! I absolutely appreciate the level of detail and thought you put into your productions Sean. Can't wait to get my 0xFE294302.
Question: Is infomercial Sean referring to the 13th key from couple years ago? 🤔The writing on the board behind him looks like some sort of a puzzle ... am I reading too much into this?? Has the key been found? so many questions
I love how that shot turned out so much
To my knowledge, the key has not been found
@@userjhansen3197 interesting 🤔
In a genre of mostly dry but informative videos, you always manage to squeeze out creative gold
or brass in this case
Love it.
Very nice good to see the old girl running. Rock solid lathe one of the best Mori Made and the Fanuc 6T is just as well made. It's If this SL-1 is out of the southern California area good chance I crossed paths with this machine. I worked on them back in the day. Have fun with it. Thank you it brought memories
This one is up in Ontario Canada! Thanks, Ill keep it going for as long as I can
the mori seiki SL-1 WITH FANUC 6T is a masterpiece with that kind of precision on the 80s , i fix two of them last year , just be carefully when homing the machine the limit sw sensor can make problem and be also the turret sw , also make sure when you send program throw rs232 port that the speed is max 4800 and you pc has same earth as the SL-1
Thank you!
When you say be careful homing, do you mean just go slow so it doesn't crash if it misses the sensor?
@@SeanHodgins yes slow speed when homming the machine and you can test them by your self go to diagnostic page and go to the registre of the home sw input for exemple if your home on x axes it x4.0 go to the registre 4 on the diagnostics and look to the first bit if it's change from 0 to 1 that ok if no that a problem
I used to run the twin turret version of this machine, with the 10t controller. It was slow as, but was still making parts until I left the firm I was working for in 2015! Spare parts (and a decent sparky who could work on the machine) were hard to come by, so good luck!
You're criminally underrated, you never fail to impress!
Thanks so much for the kind words! It really means a lot.
YOOOO THE EDITING IS 🔥🔥🔥🔥🔥
Thanks! ✋
Fuckin' love this Mr Robot format. Just amazing
For half a heart beat I heard "See My Vest" as the intro song.
Great video! Thanks
I ran one of these old Mori’s for years at a shop in Odessa Texas. We didn’t use tape, but I definitely stood there programming G-Code line for line. Luckily the one I ran recognized canned cycles, some don’t.
These things are hard to kill.
Thats really cool. I can do canned cycles, just have no clue how. Hopefully it lives on for awhile since I've moved it to two shops now. haha
Built like a tank , these old Moris
Fantastic video.
Thanks!
I used to manually program Mori Seiki lathes many years ago. I don't even remember the G-code, but there are cycle codes you can use, so it would be way less code than your cam software produce. Also the code you get from your cam software isn't very optimized which I find strange. Like the start. If the rod is let's say 50mm, it would make more sense with something like G00 X55. Z5. G01 X47. F* Z0.2 X-2. G00 X45. Z2. (Liked and subscribed)
I’m sure it’s my settings, and me being VERY overly cautious with every move. Thanks for the sub!
Worlds coolest motion control rig!
So useful!
Love the editing! Great video
Thanks, there wouldn’t be any video without it! 😁
What an incredible machine!
Just don’t see too much on those older machines. Love the contact. Your salesmanship is remarkable.
Thats how I felt about them as well. Thank you!
Looks like a cnc lathe or sometimes referred to as an auto lathe, BTW is that 4 cpus on that board? Wouldn't put it past them to have 4 mos 6502 cpus running different parts of the machine since this was before multiprocessing
I have no idea, but I'm sure they have some interesting hardware tricks in there.
i just love this, every time i see an upload i drop everything to watch it, i LOVE your channel. Keep up the exquisite work, i love the style
Wow I appreciate that, I hope your job isn’t like monitoring a nuclear reactor or something though. Lol
cool as hell
this is insane mate u need 10 million subscribers fr
That would be overwhelming haha
The Fanuc System 6 b is a very robust piece of hardware. This one of the first "modern" controls. I think its 1st control to have that fancy CRT. I'm convinced one these controls will be running when they are a 100 years old. The oldest I run was installed in December of 1979, runs almost every day with little to no maintenance. Some I/o board relays are getting wonky thou, replaced the main power supply once, and replaced the encoder cables in 2006. The other hardware is untouched in my 20 years of knowing the machine. This control made me an undying Fanuc loyalist with purchasing newer machines. It has it quirks but, if you look thru the lens of 1980. It's was ground breaking technology. Long live the SYSTEM 6!!!!
I’ll be 97 when it’s 100 so it may be a little bit difficult to test this theory but I’ll try my best!
Good luck fixing it if your break something. S1-1 is better boat anchor
Thanks for the luck, I won't need it, but thanks anyway!
for starter it would be a good idea to backup your system parameters. We had a hellasish thunderstorm one night that hit one of our building transformers and nuked one of our machines that wasn't turned off. Long story short we had to reload it line-by-line from scratch, but we didn't have it in digital backup. Our settings were all written down in the back of the Mori book that came with the machine. But there were some "secret" settings we had to petition Mori to obtain which was now merged into "DMG Mori" company. We also had to deal with Fanuc Inc. to fix memory chips on 2 boards, as well fix 3 trace segments on board that were vaporized. You think "backup, backup, backup" but don't actually do it, then shit happens and you're screwed. After about $5K worth of damage we made damn sure to backup ALL machine system settings & memory of ALL CNC machines of the company.
Ah that sounds horrible. I have the params written into a spreadsheet. Apparently I can output them on the RS232, but I don't see how to do it, and its not in the manual. Oh well, I have them saved now.
@@SeanHodgins It's fairly easy to spit it out via RS232. We bought a small laptop for it so I could back them up, we later evolved to putting them all on a network doing it from one machine. You'll need some DNC software, and a null modem wired cable. The machine should already have an RS232 port on it, either in back or near the mainboard area. You'll need to set some parameters, i.e. baud, error check, parity, etc.. All of which you should find with your book on the machine, or even written on the inside panel cover. Fanuc are usually "nice" in making sure that info is available for your machine. As for output most likely that will be in ISO format, unless your machine or software prefers EIA. You're also going to NEED to buy a USB-to-serial-port converter for the RS232 cable. They work hand in hand. Device found here cnc-specialty-store.com/rs232-cables/rs232-usb-to-serial-port-converter-adapter-for-cnc-fully-tested RS232 help via phone is available there as well to help you. To help you walk through what is needed.
I know about a machine like this sitting in the dirt. Basically the shop closed and the owner took what didn't sell to the backyard. Actually I know of 2 machines sitting in yards.
Great video, the Mori Seiki was THE high speed CNC lathe of it's time. Thank you.
Still pretty high speed to me, it will be awhile before I really push it. Haha needs proper leveling and feet as well
Nice! Had similar adventure some years ago, with a Hermle uwf-851-mill
I love hearing about all of these different machines in the comments. Was it a good experience?
@@SeanHodgins It was the biggest sucsess of my life.
We buyed it for dirt cheap (for 500 eur), with my brother, because it was faulty (Crushed z-axis thrust bearing) and the company who selled it, started to disassemble it, cutting all the wiring, even the linear scale cables, what was fun to resolder.
Luckily the machine came with a complete wiring diagram, so i was able to rewire everything, and start the machine.
Then we realized the problems, and we complete dissassembled the whole thing, ordered the needed bearings, give it a fresh new coat of paint, and assembled again. My brother is the hardware guy, i am the electrican/software. So it was really fun, for both of us.
Back then we worked at the same company, had lots of free time, and good relationship with our boss, so we were able to do the repairs after work hours at our workplace. Then we moved, and strated a small company, then moved the old lady again, and today She sits beside a Deckel Maho DMU70v.
Whatever happends, she stays with us.
We helped She to live again, and She helped us to start something new.
P.S: Sorry for my terrible English, i am Hungarian
We have one just like it. Has paid for itself thousands of times over. Continues to work day in and day out.
It comes from a time when people thought that if the tool comes from the back, the x dimensions have to be negative.
Also, it doesn't have some handy cycles so when programming manually, the guy has to write out a peck drilling cycle by hand.
Very cool. Yeah the negative X is strange, but I also only have little previous experience with any CNC lathe so it doesn't matter to me much. I've built it into the way I setup my CAM software.
I haven't really looked into the macros yet, not sure if I would ever need to unless I'm running different parts non stop.
@@SeanHodgins If you look around the circuit boards, you can find some gems. Intel 8086 and such. The purple chips are Fanuc's own. Under the little metal plate on top (don't remove it), you could see the magical piece of silicon and the tiny etched lines that make our world tick (I salvaged a few from a similar machine that was scrapped and soldered the plates off). Also, there is a ton of UV-erasable EPROM chips that each has a little orange translucent sticker to prevent stray UV from getting in.
Mori SL1 is/was a nice machine. Wow, how the electronics changed.
I was going to buy one but shipping was too much.
wish it could be cheaper, but it pays for the energy required, and the people to deliver it! 😁
@@SeanHodgins I was going to buy one but the shipping was too low. Please fix.

Took me a second to recognize the song, but from the second note, I knew I knew, it. Lol
Also, kinda mad I'm so late to this video. RUclips has been so shite about telling me about videos from people I follow.
Happen to actually get one about your just posted 'months on hard mode' went to go watch and was like WTF?! Cursed RUclips and started from oldest I haven't watched and will work my way up to current.
So good I have a bunch of videos and projects to watch, bad for the creators like yourself I follow for views etc and RUclips as the user ire for them continues to mount...
Anyway... With that off my chest into the Internet void...
Back to the video!
Such a great video! Looking forward to what you have in store next!
Thanks, I have no idea what’s coming next 👀
sl-1 the first cnc I operated, over 40 yrs ago.
After a long time ❤
Hype
Sounds like it ran out of MEMORY!are we detecting some old Chinese spy whare 😳😅 try shoving some Chinese characters in that baby
Having suffered through a similar project myself, i can recommend to change your PP to only add sequence numbers on tool change. It dramatically reduces the filesize and transfer times while being funtionally an improvement if you need to jump to certain operations.
That is an excellent idea, I hadn't thought of that. Searching without the sequence numbers is just as easy since a computer screen is right there.
bro, I'm equally amazed you got space to store all of those beauties. I might be hyper jalous. Anyway awesome vid
I'm still amazed every time I walk into the place.
I just stumbled across this channel and this video was ART. Fantastic work! Welcome to the world of old ass machines!
Thanks! Now I just need to keep it going!
I wrote a program to send programs to older machines like this right in Fusion 360. Send me your email and I’ll give you a free copy
Also, are those really steppers? You should do an ether cat upgrade with Mach or Linux CNC
I've been corrected here in the comments, they are DC Servo motors!
I would love a copy, sean.hodginsa @ gmail.com (minus the spaces)

vrry good
Consider making movies for Netflix. You can do much better than most Netflix series. As a hobby machinist and hobby filmmaker - I am seriously impressed!
Would love to do my own mini series.
Is Karl Casey's FM music from a real instrument or software?
I don't know, but I imagine he uses some real instruments and some synth instruments.
Man you should update that with a Centroid Acornsix.
I’m not against doing that, but it’s also fun using the old school equipment.
😂😂😂 I've worked in the control panel of a 30 year old cnc lathe and my goodness the electronics were dated. Fortunately for me Bosch rexroth and Heidenhain did have some parts we were able to retrofit to make it work. 😅
Haha, it could be destined for a retrofit if something big fails on this one.
The real answer is definitely why not.
Its always why not!
people still prgram these manually, they have canned cycles so you only need the geometry for the final profile. and the stock size
My last job had that exact same model. It was our smallest CNC lathe in the shop.
Correction, it was a SL-3, and I have ALL the manuals for it. I'll see what I can find for an email address
Very cool! Let me know
Wow woah that shot from 7:08
🙂
Wow, this was great! It's been a long time since I've seen so much creativity and ingenuity packed into a youtube video. And the machine is sick, very jealous! Hats off!
We have Mori Seikis in Ansaldo Energia in Genoa, we use them to produce the smaller blades for Gas and Steam Turbines. The versions in the Blade Workshop are now newer than this one but fairly sure we used one like this one 30 years ago.
My old boss was one of those manual programmers. Hunched over typing in code for half a day chain smoking and downing coffee.
Oof, yeah and that’s after doing all the manual math to make the shape.
4:50 that nice joystick even not exist in modern machines.Japanese just does best even 40 years ago.
Its really amazing quality.
Neat video!, what software did you use for the post processor or was it in fusion 360?
Yep m, I used fusion 360, with a modified post processor file for my machine.
I'm jealous.
Now I just need to put it to use.
Sean, you are an inspiration to makers everywhere! writing, editing, Shots, lighting. and a unique promotion. Fantastic! just saw this, spinner is already at 8 bucks.
Thanks! Yep $8 almost sold out. I think the ideal price is $16 so still a deal. Lol
at least its a mori seiki .. worth the effort :)
Definitely worth it!
Awesome video man!
Thanks!
Nice!!!
Thanks!
Wow, been working on SL-1A long time ago
I can't believe how long they have been in service!
what software you use to send g-code to your pc into cnc?
Love ya
Right back at ya.
