Thanks for the positive feedback on this :)

Hi Marion, I bet you drove your Mum to distraction :)

Hi Ed, Yeah, that use of a dovetail on the side of the dross slide is something Schaublin did a lot. Seems really convenient.

It is pretty stringy though. Luckily this didn't birdsnest on the the initial deeper cuts.

Hi Joel, Thanks for the sanity check on that. You are right, although that was an F50 feedrate, and I had dry run that program twice, it was not a good idea. Once it turned to custard (the knurl wheel catching on the tip of the work), the big picture was lost there fast. Should have done the knurling as single pointed, multistart, LH and RH coarse threads, which would have been: 1/Safer 2/ Cooler

Thanks Willem. I appreciate the feedback. Please spread the word :)

At least knurling the the plastic cleaned all of the swarf out of my knurlig tool :)

Thanks lot Maros. It helps me with that motivation.

I had similar idea, first finish shed and then I can start....maybe

@@DreitTheDarkDragon It is a pretty big commitment of time. I find it helps me stay focused and not abandon bigger projects, but, makes the progress slower.

Don't worry, everything takes 5 times as much time when you make video's about the projects so you should be set for the foreseeable future!

@@RotarySMP Exactly, it is hard to understate the time and commitment needed. I noticed that I plan to publish my next video... for about 4 years now. Damn time flies! I've moved to a new home in that time, had a workshop on the second floor for a couple years and am now moving to my brand new custom design (my own design) workshop behind my house. I still plan to make a video, really :P

Thanks for your feedback and kind offer :)

True. Would have been a better result in this case :(

Yeah, it is not done yet though. Will be a lot nicer to use once I have the control module and the jog wheels done. We have jokes too you know :)

@@RotarySMP 😂

Yeah, I normally hook up my vaccuum. Should have this time. The metallic binders can be carcinogens.

It is! Takes ages to get it set up, but can do nearly anything.

Thank you! Cheers!

This is a real benefit of CNC, as you can creep up on a thread by simply increasing the K value of the G76 , and running the code again. linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G76-Threading-Canned

Glad to supply half of your drugs :)

@@RotarySMP well im hooked for sure :D

@@fieur Thanks for engaging. It helps.

Thanks Phil. Since this is in photo chemistry, I didn't really want metal there, although stainless is probably okay.

Or leave the shaft hollow and slide a bit of plexi or polycarb rod in with a little dab of CA glue to secure it. You could conceivably use fiberglass (or even glass) too. But doing it via CNC lathe is definitely the coolest way to do it!

@@davidedwards9157 Thanks David.

Thank you for the kind words.

Thanks. It would have been faster to do most of this on the Boley, but if I dont use it, I will never get good at it.

Hi Jasper, it is a real benefit of CNC. I threaded to 0.1mm of the shoulder at 600rpm :)

@@RotarySMP WOW!!

@@jster1963 Bit of a pucker factor when you first do it. :)

@@RotarySMP I bet!

Thanks James. I didn't think that through. If I had approached the work wiht the nurl in X it also would not have happened.

Thanks for the feedback on that tool grind.Next time I need one for plastic I'll give it decent rake.

@@RotarySMP awesome. When CNCing plastics just run heaps of rake and heaps of side and front clearance angle to avoid any chance of rubbing. Melt will be your biggest problem, tool wear and tool tip strength are pretty much meaningless.

@@wizrom3046 Thanks. That makes sense. I just had issues with it grabbing and pulling out the part in the Boley, but that was bad clamping.

Thanks Robert. I still have a fair bit of work to do on it before it is finished. The tool changer, the control panel and pendant, and get the name plate clean :)

Thanks Pete, I have used it a few times in recent videos.

Thanks for the double support this week :)

Hi John, I have turned a few parts on the Schaublin in previous videos. It is nice to be using the machine, even if it still needs the control module made to improve the interface.

Thanks for the feedback Samuel. It helps.

I considered that, but needed to exercise the lathe, and since it was not my design, I would have had to model from the STL, which I find to be a pain.

@@RotarySMP that’s basically my day job. Happy to help if you ever need.

@@The.Talent Thanks for the offer.

Thanks, Still need to make the control panel, and do a fair bit of config work to do. Then comes that tool changer.

Hi Jim, Nice to hear from someone who used a Nova. Another Schaublin owner I know framed the core memory module and hung it on the wall :) The Fehlmann stuff is a good basis for your project. Good one.

Thanks Werner. I still need to design and build the control module, and pendant, but it is nice to use such a nice machine.

:)

But you need quite thick filament to feed Schaublin!

Good point. There are lots of options

It is nice to use it. I look forward to making the control panel and pendant to make the user interface more inituitive.

Interesting to see Morbidelli having an easier time with the Yamaha than Quartararo this weekend.

@@RotarySMP I like all the riders so it's always good to see one come out of the doldrums. Franky hasn't shown that kind of form in a while, but wet weather always seems to do strange things to the bike set up, Zarco said in an interview that he was able to do his style in the second half of the race once the tyres were more worn... He was rapid!

@@wmc7870 Yeah, Frankie was hot at the end of the 21 season, but had a nasty injury didn't he. The Yamaha and Honda give the impression of being nearly unridable for some of the best riders ever.

It's strange, I have to agree, but the tolerance from a winning 'best bike ever' to an unrideable machine is less than 1 second a lap or so! That's why I like all the riders, they must all be unbelievable! When the circumstances are right they can all shine, look at jack in portimau!

@@wmc7870 Absolutely agree. Much more interesting than the F1, as whoever is best on race day wins :)

Thanks for watching. Happy Easter to you as well.

Hi Heather. Yeah, I set that to thread up to 0.1mm of the shoulder at about 600 rpm. That would only work manually with a lathe that has a reliable auto kick out mechanism, and an undercut. That porosity of spaghetti printers is a nightmare for my Beatles castings. The next one has a few layers of sellac to seal it.

Thanks for the visit

Good point :)

Thanks.

I have been neglecting the nameplate :)

Yeah, it looked like it should be down with clean knurls too. Like this it cleaned all the chips out of the knurl wheels. I could have cut the knurl as a multistart, course pitch, thread cut both LH and RH.

Thanks Chris. It is not the first time I have turned a part on the Schaublin, but every step forward feels good.

It was printed in PET-G by a mate who is really good at 3D printing. It might be a bit stronger with more infill and perimeters, but it will always be under a lot of stress.

Thanks for the comment.

I didnt comment the INI, as it the behaviour is obvious. What I need to do is compare the wiring with the wiring diagram I drew, as that is probably now reversed. I should update that.

Thanks Mark

That could have worked, but now I have a the turned part, I dont need to.

Edified… oops - wrong place for my comment😜

Good suggestion Lloyd. Thanks.

Yeah, multi start coarse threads, LH and RH would handle the knurling.

Thanks Wendell. Those guys a re nuts, and lack the self preservation instinct. This season may well be last man standing. Awesome start by Binder in the sprint race, and great ride by Bez in the main one this weekend. Great how many competitive riders and bikes there are.

@@RotarySMPthe series was better without you know who then his return proves me right...

@@wendellg1 I liked the way Marcez could "uncrash" a bike.

Did you see all that snot run out of the turret when I clamped it down? I expect it is all gummed up with the same coolant soup which gummed up the lead screws as well. I plan to strip it down and clean it. After that I still need to connect it's air lines to the Festo pneumatic module, and then just assign pins and some logic. There are some LinuxCNC components for lathe tool changers out there, hopefully one will work with the feedback logic of Schaublins tool changer. Good idea on the commenting the tool better. Although by the time I need it again, I will have needed the 6mm ER25 collet for another job, and will need to reload it and touch it off again.

@@RotarySMP I did notice the shmoo, but don't like to judge. I look forward to the teardown/cleanup and commissioning though. More great content. You could always make more tool holders of course....

@@squelchstuffA mate here in town just pulled down his 125CNC tool changer, so I asked him to take lots of pictures and video. to help me when I get to that point. I am going to need to make more of the normal tool holders as well, but that will be more work. The ER ones should be pretty easy for the Schaublin to make for itself.

Yeah, takes me ages to get to this point.

@@RotarySMP I can understand because I'm a loyal viewer

@@junchang132 It will be more convenient to use, once I have the control panel designed built and integrated. Still, it is nice to use it.

I suspected the same thing. Sorry I missed that.

I got the motors and drivers from JMC, and the connectors and cables were included. I am sure all those connectors will be standard, but it might take a bit of searching in the RS Online catalog to find them.

That is a good idea. Most of the chemicals only need intermittant agitation, but bleach bath for R100 needs continuous.

Not really, I just touch off, which works fine on diameter, as I take a fine cut and measure, but dont have a goo solution for Z other than the finest of touches to the same face zeroed after the first tool.

@@RotarySMP If it helps at all, back in the dark ages before built in tool presetters ,this is how we set up mori seiki's with FANUC controls. I do not recall specific g-code or parameter settings ,they might have been specific to mori but definitley fanuc specific Once set it became the permenant absolute co-ordinate system. For the Z axis we would bring the bare turret forward to touch the turret face to the chuck face. this position was entered into machine parameters for the X axis a bar was placed into the chuck ,turned round and measured (diameter did not matter) we would then touch the X face of the turret to the bar. using the bar diameter plus x position this is recorded in parameters as well. If done correctly, the intersection of the x and z turret faces become tool offset 0,0 . at this point if you commanded x0,z0 the turret would move to touch the chuck and be on diameter x 0. once this is done all qualified lathe tool holders have exactly the same z and x offsets. for 1-1/2" tool holders for example , that is .250" for Z and 3.00" inch for x diameter. Boring bar holders all have the same diameter offsets as well. so why bother? all of your offsets in the table are values that you can just look at, or check with a ruler to be sure that they make sense before you even start final offset tweeking. There is one more step, as the chuck face is z0 you need to apply a work offset, as simple as mounting a work piece and measuring it face offset from the chuck.

Fomaoan R100 is a B&W slide film, and it has a chemical bleach bath which needs constant agitation. The developer is a typical agitation of a few seconds per minute.

@@RotarySMP ah, it's positive, gotcha:). My point was from getting into documentary photography at the tail end of film use and having to learn to develop and print myself. And it turns out agitation means different things to different people. Some people swoosh the chemicals around, let's say they agitate more or perhaps even aggressively. But without name dropping I heard that one of the best photographers of the past 30 years insisted his tank was gently rolled, never swooshed. And that it was always developed at the colder end of the range, if I recall correctly. He tended to push a lot of his rolls, too and felt these two things kept contrast and perhaps even grain at bay. Later on, I found others did the same. Anyhow, I am not surprised you know your stuff on this subject, too and it's amazing to hear you're into 16mm:)

@@AntiVaganza I have been standdeveloping 35 in Caffenol lately. Really nice results with a 70min dev. The bummer about 16mm is there are so few film types. OWRO should have UN54, but they seem to have stopped making it. Kodak double-X is really expensive, or Fomo R100 has the finicky bleach reversal process.

Hi Micheal. That was a video editing experience. I fast forwarded it coasting to a stop the first time, cause it took so long. In both cases it coasted down. I did a wiring diagram of how I connected the VFD. It is discrete wiring. I think there is an on/off signal, and a wd/rev signal. I am assuming that I have an open circuit on the drive reverse line. I used a CAT 6 cable for that line, and the wires are pretty tiny. Maybe I pulled on it too hard at some point. There is a mechanical brake on the motor, so I didn't put a braking resister on the VFD, but let it coast to a stop. I need to connect up the brake at some point.

@@RotarySMP Hi! That explains a lot. But it sounds so real, really like braking by VFD in first case, I really couldn't say it was sped up. Might be broken wire, some pull-up/down resistor settings (forcing default state to opposite than you need) or something in VFD configuration. I think I also saw some driver in past which needed DIR set sooner than RUN and didn't cared about any change of DIR while it was already running. Meanwhile with some ancient VFD I can switch DIR any time I want and it changes direction instantly. Good luck with finding where the problem is! Also try to measure voltage on mesa card outputs when VFD is ready to accept orders, it might be pulling some signal to wrong state. At work we have on bigger drill and that mechanical brake fascinates me. You'd say it's quite a big piece of metal....CLUNK! and it stops immediately. I'm wondering how that would work with lathe, if inertia won't break parts in chuck when you brake it quickly. Also I think you can set VFD output to control brake, so it won't engage when VFD is forcing motor to move in some direction. You can then even set some slow ramp down to almost zero and then it will automatically engage.

@@DreitTheDarkDragon Good ideas. This is a pretty nice VFD, but and I think it has a output which could be used to control the brake. Need to look that up.

@@RotarySMP Hope it helps. I know most of VFDs have at least one relay output and there's usually configuration which holds relay when VFD is "running" - which is in some cases separated in more configuration options.

@@DreitTheDarkDragon I was thinking of using a LinuxCNC signal to control the brake, but that is simpler and probably more reliable.Thanks.

LinuxCNC is feed with the spindle encoder, so it knows the exact orientation all the time. I was using the G76 multi pass threading cycle, so all I needed to do was to amend the K value, to increase it, and run the code again. This is where a CNC really shines, you can thread right up to a shoulder (I think I left 0.1mm), and at a high enough spindle speed to get goot surface finish. linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G76-Threading-Canned

@@RotarySMP Thank you very much for the reply. I still have a little question. You ran the threading cycle again after checking with the nut right. So when after the threading cycle is finished it usually stops the spindle synchronization right? When you start another threading cycle, the start point will be different right? I have linuxcnc running with my okuma mill and I think this is same as doing rigid tapping. If i go again thread start point is different resulting in mangled threads. I believe you can understand where the confusion is. I've no experience with linuxcnc on a lathe.

@@harindugamlath LinuxCNC uses the index pulse of your spindle encoder to synchronize motion. So if you have an encoder that has more than one index pulse per spindle rotation you can get synchronization on any one of the index pulses. For instance, if you're using the spindle drive motor's encoder and the spindle is coupled to the motor at anything other than 1:1, you will get unpredictable results.

It was a pretty ratty RS232-->µUSB with only 3 wires. I wonder if it got swept up with rubbish?

@@RotarySMP is very good theory

@@MakarovFox Would be finny if I dumped it while cleaning up looking for it. :/

Hi Andy, I swapped the labels when I swapped the cables, then swapped the labels back when I swapped the drives. I need to install your Macros.

It sounds like that to me as well, as I have ear defenders on. I pull down the ambient audio track when editing :)

@RotarySMP even with filtering you can tell it is just a low noise machine. Probably because it is fully belt ran.

@@Oberkaptain That big tooth belt is pretty loud at speed, but otherwise everything is very smooth.

Yeah, I get that. This is not a million dollar shop, it is my basement, and I bought the mill and lathe with dead controllers for a couple thousand each, and converted them to LinuxCNC, but then use them to make valueless parts :)

@@iteerrex8166 Good point, and having the manufacturer support, so all the machines talk to each other.
