I tried looking up that printer but got something slightly different. Did you mean Prusa MK3S+ ???

Oh yes you're right John. MK3S+. I fixed the post. The company makes their printers in Prague, Czechoslovakia! Amazing. There are different companies now shaking up the market with faster or far cheaper models. I've taken the view that your project can be the printer itself, upgrades, fixes, tweaking OR your project is making stuff and the printer is just a tool. The later is what I want and this printer has done that for me.

Very nice animation of shaper mechanism. It clearly reveals just how the arm retracts faster than the work stroke. The pivot point moves changing the speed of the lever. it's very clever I think. I just learned this today. Anybody with a shaper take some photos with the covers off? (@kevin.decelles I think you are the reigning shaper champ?) ;):D

Not the best shots..... These are of the inner workings of my Butler shaper. The yoke on this one is significantly larger than the one in the smaller one...

I am 100% on your page. I love making things but a 3D printer isn't gunna be one of them. Maybe 30 years ago, but not now.

One of my friends is almost 80. Another finally passed at I think 88. Both jumped into the 3D printer world. The one does amazing things with Fusion360 and his 3D printer. I mentioned to him a link to a harmonic drive that was 3D printed. Next thing you know he's built one and improved on it. Then machined a bunch of it with his CNC lathe and mill out of metal because the hot stepper motor started softening the plastic.

Our brains, as we get older, need to be challenged with new things. Not the same old same old.

Believe it or not one of the the best thing for the aging brain to offset the chance of dementia is something as silly sounding as ballroom dancing. Because it involves exercise, music, planning on the go, co-ordination and teamwork it simultaneously challenges enough parts of the brain at the same time to keep it healthy.

Taking on something totally new like 3D printing means not just printing STL files off the net but then learning enough CAD to generate your own STL files. The fun and exasperation of making things.

And a different kind of reduction drive. Again, much easier to experiment with in plastic. Even if I never make it out of metal I've learned so much.

Just say'in.

It's a nice printer and I've printed many many parts with it. Thanks @Jwest7788 for encouraging me to just spend the money on a good printer.

I live by the Adam Savage rule of thumb, "buy the cheapest version possible, and if it ever needs to be replaced then buy the best version you can afford".

However, there are definitely some items where it's easier to learn from others who have been down the path.
The pain of trying to get higher-than-realistic quality out of a cheap 3d printer, is worse than just buying a nicer one in the first place. Definitely one of the few exceptions to the rule of thumb. haha
 
I agree. I bought the cheapest and it's been good to me but I also have very low expectations for quality. As a result I haven't been disappointed. I spent way more on my POS Delta 3D printer. After many years it's finally operational but until I make the rest of the improvements the quality isn't there either. But sure is fun to watch.

At 77, one could call me almost 80 too.

"finally" doesn't sound too exciting.

Who knows, I might do the same when and if I get there. For now I'm happy to use one that is affordable and works well out of the box.

It's not like I don't have many other things to learn and do. Farming alone is an adventure.

I agree completely. But I would not want building my own 3D printer to get in the way of more exciting projects. There is nothing same old same old about my life at all!

I actually love dancing and so does my bride. I'm not as skilled as you are, but we enjoy ourselves whenever we can. Our biggest challenge is finding someplace to dance. But we have been known to dance on the lawn under the stars. A while back I borrowed a zero turn lawn Mower. They are amazing. I learned to do a waltz with it! I had to let it go though. They like to swim more than they like to dance...... :eek:

This is my goal right now. But first I have to learn Fusion and then convince my bride that I need a 3D printer.

It's all good John. Thanks for the ideas. Pretty sure I'll be ok. I'm not remotely a couch potato.

A picture of the yoke in my largest shaper. The bevel gear for the adjustment handle can be seen. Turning the gear move the slide block in the yoke there by changing the stroke. Speed is controlled by a transmission or cone drive etc. a 2” stroke will take the same time as a 18” (motion wise ) because the bull gear needs to travel the same revolution . Turning the bull gear faster increases speed. But yes, return strike is faster.
