lol, when a 5mm bent screw causes the whole axis to wobble then there is something wrong with the design. Most 3d printers i have seen are more rigid than this.

He's done Finite Element Analysis on a computer which tells him it's all good so you must be wrong and I must be wrong for agreeing with you.

What you are seeing is a motor bolted rigidly to the end of a shaft and being allowed to wobble. Much easier than messing with universal joints or isolating it with toothed belts. I have been suggesting it for years so it must be clever

See what a formal engineering education and Finite Element Analysis can do for you?
Sweet Felicity Arkwright it would seem!

Ye real cleaver.!!! . . The Drives will love dealing with all the resonance banging thru that motor...

Here's one from a few years ago - at a Pneumatics Suppliers Counter in Nottingham.

Me: Can I have one of those XYZ-123/B, like the one that's on the shelf over there.
Jobsworth: I'll just look it up on the computer. Sorry mate we haven't got any, computer says zero stock.
Me: What about that one there!
Jobsworth: If the computer says we 'aven't got any, we aven't got any.

Cheers,
Rob

I bet he was an engineering graduate just waiting for that big design contract to drop in his lap ;-)

Not all of us graduates are waiting for contracts whatever the sun and mirror lead you to beleive

Oooh! I love it when you get cross, can I call you Mr Spanky?
