Building a model steam engine yet?

On the other hand, Fusion360 has more stuffs, like integrated CAM or finite elements computation, which I would love to use. But I'm using Linux...

I didn't know but apparently Autodesk is bringing Fusion to the browser. Presently only the modeling workspace, but they add CAM and the rest that would be quite nice! Just briefly tried the modeling and its smooth, at least for small simple parts like most of my stuff is.

Getting back on topic, I've been busy making more parts with my new toys. If anyone is interested I've done some write ups on my blog.

I'm totally stealing the ideal of using an O ring on the lead screw nuts to give it some self alignment leeway. Glad to see you're getting some good use out of those new ~~toys~~ tools.

Feel free to steal - that's why I post all this stuff. I don't really know if it's totally necessary but it seemed like a good idea when I thought of it a few years ago so I've stuck with it. The digital dentist ( @mrehorstdmd ) recently did something similar to allow the bed the "float" but I think his concern was more about thermal expansion (I could be wrong - I didn't read his write up fully). But I have 12mm of insulation between the heated bed and the frame that the mounts attach too, so I'm not concerned about that.

"Toys" or "tools" - they are one and the same

@deckingman I have no idea what you're referring to...

@mrehorstdmd I remember reading about a clever way to attach a large heated to bed which would compensate for sideways thermal expansion that might cause binding of the linear guides. I don't remember the exact details but I thought that was you. Clearly I must have been mistaken. Apologies.

@deckingman @mrehorstdmd I think you mean this blog post where the bed is mounted on ball-head screws and one (some?) of the counterparts are slots.

Yes, I think that was the one but as I said, I didn't read it fully so might have been wrong about the thermal expansion part.

OK, yes, the bed is on a kinematic mount that allows it to expand, and the X axis linear guide uses two bearing blocks, one of which allows the printer's frame to expand without side-loading the Y axis linear guides.

Here are the relevant links:
