Carvera Soft Limits issue
Просмотров 213 месяца назад
Out of the blue this soft limits issue meaning that I can only run 4th axis jobs (haven't checked 3 axis jobs) by switching Soft Limits OFF. Especially confusing is that GoTo anchor one is OK despite the fact that the spindle body has to travel much further.

Out of the blue, when trying to run a job which I have previously run without a problem, 2 seconds after the spindle has been started the z-axis moves up and trips the z-axis safety limit switch.

Fish, misc and lock stuff at Ballard Locks
😮 who R they ???
Thank you for sharing this; it was very charming.
Amazing footage! That looks like a huge fish (do you know what kind?) the bird caught and ate near 1:09! The fish was struggling, but the hungry Cormorant managed to fully consume (alive?!) it all okay? It looked like the unlucky thing was desperately kicking sliding down that long throat! I wonder, does the large fish stand any chance of escaping if eaten in that condition? Maybe it can turn around inside the elastic throat/stomach and has a chance of survival here.
Thanks - I'm sorry but I don't know what kind of fish. And, yes, they swallow the fish while the fish is still alive. Not the way I'd like to go!
Thanks man, im trying to make aa lightsaber, and its helping a lot
Yup 😊
I want to put a motor to give me about 500N force (cpr machine) using this mechanism and use arduino what should i do

Unfortunately I think that friction would heat up the plastic quite quickly and the rotary piston drive would seize up.
I've never seen such a colorful crab.
Nor me!
Seven years and no comments!? How dare they not chime in on this hot mech! Thanks! ⚙️
It was worth the wait.
Hello, I think by making the teeth slightly bent they can limit rotation to only one side, if the shaft is the input and gears are output.
Would you mind if someone try making an engine from this design?
Not at all.
@@mgg942 thanks
Super.
Thanks.
I need 10 hours of this
That's what she said. ;)
that is fresh and clever!
Imagine an engine using this concept
Somehow, the bug managed to resist and keep trying to escape. A true comrade.
Very cool
What did u use to make this
SimLab Composer Mechanical
Nice
Washing machine?
Hadn't thought of that! But I suspect not...
The fish stands any chance of survival/escape at that point too?
Amazing footage and interesting information! That looks like a huge (do you know what type?) fish she gulped at 1:49 here! The fish was fighting, still, did the Cormorant swallow that whole thing alive?! I wonder if the
Thanks. I've been told that the fish is (was!) a flounder. It's difficult to spot in the normal speed footage but if you watch the slo-mo you can quite clearly see the fish being swallowed.
Awesome
Thanks!
yes but you have to turn it manually whats the point?
True. Absolutely pointless, Fun designing though.
Just modify the model so you can attach a motor?
Is this handheld??
Yes. Stabilised in DaVinci resolve 17.
Now this is a very interesting iteration of this mechanism. It spawns the idea that this might be more useful than a conventional geneva mechanism, for instance in applications where space saving is of importance. is there any chance you might publish the printing files for this?
Some time ago on Thingiverse: www.thingiverse.com/thing:1252585
@@mgg942 Ah of course. Greatly appreciated! Very cool 3d printed works, you should do more.
That looks a lot more linear than using a bell crank. I know it's all just plastic, but would roller bearings in a track make this much smoother? I'm thinking that the force applied at the ends of the range of motion would have angular force creating friction on the sides of the moving slugs (?) as it is divided between the moving slugs and the stationary pin. (I'm turning 50 and I've always wanted to get into some robotics and physics-related real-world stuff, so I'm trying to figure out how to start out. I had a rudimentary physics class in the Navy in the 90's and realized that I missed out.)
Это конечно круто, но почему спустя 5 лет?
Почему нет?

Nice
Ta.
That's really cool made :)
Thanks.
their starting acceleration becomes high. Therefore, the forces also increase.
Cool. Well done.
Thanks.
Can't see your comment, Ricky Funk, despite the email notification that I received. Anyway, the stl files are available here: www.thingiverse.com/thing:517073 Mike.
This looks like a more efficient way to convert rotational motion back to a reciprocating motion, like for a Sawzall.
This looks pretty cool. Is there a practical or real world application for it?
Off hand I can't remember - too long ago. Sorry!
perhaps a way to convert rotary motion into alternating rotary motion
good job
Thanks
Is the flexing intentional?
No. At first I though that it was due to manufacturing tolerances. Later on I simulated the model in SimLab and realised that there was a design error. This has been fixed in an updated posting on Thingiverse - but I didn't make and updated video.
What kind of mechanism can be used?
Could be useful in certain applications. As far as I can see, the small gear could be easily counterbalanced with a weight on the pink wheel. It could be useful in a low vibration machine. The drive doesn't exert a radial force on the linear bearing either.
Beautiful!
Nothing like a good bath
How did you make it
3E printing.
More of a “drinking bird” simulator than a bird scarer.
Guess that it would have to be a timid bird.
The second plane looks like a DC3 to me!
Very cool! Thank you for sharing! I'm making a clock, and I am going to use this escapement!
Excellent - look forward to seeing it.
One more question, hopefully, what program did you use to create this animation? I withdraw the question, I see now that Blender is a program and not a persons crazy online nick, as I thought at first glance.
Blender, as you noted. These days, on the odd occasion that I need to run an animation I use Simlab Compose which is NOT 'free' but has a much less steep learning curve.
Thanks, @@mgg942, for the reference. I saw that Simlab has a trial version for 21 days and a lite edition. I do not need the program, at the moment, but will after I redesigning the rack; to show my colleague, and interested parties, the animation, of a near working model.
I am using Sketchup pro, for measuring the dimensions of all the gears, in the reciprocating stl's, and noticed it also has an option, to export as an animation. Would this be a good option to create a similar animation, to the one you made? I am also a newbie, when it comes to designing gears, and noticed the gears teeth from "gear_l_01.stl" and "part_l_01_15T.stl" are not of equal dimensions. Is this by design or an error? I have a jpg depicting the two gears, Sketchup, if you would like me to share.
@@rodmanunderhilliii8198 Roman, I'm not familiar with Sketchup. When I started 3D design, 6 or 7 years ago I tried Sketchup and a variety of other programs before settling on MoI (Moment of Inspiration). So I'm afraid I've no clue about the capabilities of the current version of Sketchup Pro. As for your question about "gear_l_01.stl" and "part_l_01_15T.stl" I don't understand your question as the gear_l_01.stl is a full gear and part_l_01_15T.stl is part of a larger gear. At any event I doubt that I'll be able to provide a useful answer as I designed those parts over 4 years ago. Mike.
The spacing between the gears teeth are not the same, and since I am new at creating gears; I am asking if that is on purpose. See the picture I exported from Sketchup: imgur.com/a/HKQhpPt Left Gear Right gear 8mm 10mm thickness 4mm 3mm width at tooth base 2mm 1mm width at tip of tooth these do match: 2mm 2mm space between teeth 4mm 4mm tooth length
I also posted, on your other you-tube video, of the reciprocating gear. I noticed, in the animation above that not all the teeth, on the "rack", gear, are being used. Is this just an animation thing, or are not all the teeth being used? I only ask because that rack gear will not fit on my xyz bed, and I will have to resize the entire build, unless I can possibly leave out some teeth on the "rack" gear.
I think that some teeth can be omitted. I'll see if I can find the one that I made and will confirm one way or the other.
Thank you, no hurry's; I do also plan on arching the rack gear slightly and mount a photo diode on it, but not until after I learn the math.... to calculate the arch of the rack.
@@rodmanunderhilliii8198 Looks like you could leave off 20!! teeth. I don't know why I made the rack so long - perhaps merely because I though that it looked more balanced.
wow, that many.... I will count the teeth on the gears: 22 on the main gear, as well as the two gears on either side, and the reciprocating gears have 15. I'm not sure of the "gear teeth" math, but it seems, I can add 7 more teeth, to each reciprocating gear, or perhaps subtract 7 from each side of the rack gear. This is good news for me, since 20 teeth on the reciprocating gears, would seem to be the best number of teeth, for my project.
Very cool, this is my number one choice for the project I'm about to work on. That's also a great link you posted, above 'mechanism 123' . I spent hours looking through all the different mechanisms, then found your post, on thingiverse.
Glad you like it. A lot of the mechanisms are fascinating.
