Ballscrew & Linear Rail Kit - Any Good

[A_Camera]

Hi A Camera

Just been on your channel - cant believe you actually CNC in your house?

That's what it looks like!

Yes, you seen it right. I have a fairly large room, which is a home office / hobby room / software, firmware and electronic development center, photo studio, as well as other hobby activity room. My CNC and my two 3D printers are used in this room as well. However, I NEVER use any liquids to cool and lubricate, I print only PLA and PETG, my spindle is air cooled, my CNC is covered around and I use a dust shoe when milling PCB and most other things. I don't mill any wood. Anyway, this solution suits me well.

Like the actuators, totally wicked idea - i just use the mechanical leverage style ones in the workshop.

Thanks. I made that mod a few months ago. Got tired of the primitive method I used before when I had to move my CNC. It is just soooooo much easier this way. Now I can easily clean behind the CNC or make any sort of modification / improvement or whatever which may demand moving the machine.

I also hope that you are not going to use that tablesaw in your house - that will make a mess!

That was only opened, unpacked and "dry" run for a minute in the house. It lives in the actual workshop / storage are (a separate building) where other machines and tools are.

Just had to read up on PLA - I am in the recycling industry and i have never heard of it - so its a biopolymer, but not a commodity polymer.

Looks like it composts well!

What do use it for? Is it brittle, it does not sound like a flexible polymer?

How do you get that text box when responding to just part of someone's comments?

Just tried it and it did not work?

Thanks

You can also split the post that way, or edit if you want to, like the message above, where the finishing quote in brackets and is missing.

There are many qualities. I try to buy good quality (not necessarily cheap), made in Europe PLA. Yes, it is recyclable and the fumes are non-toxic, so I don't need to take any special precautions, or venting. PLA is the most commonly used plastic for 3D printing and is environment friendly, I think it is made using corn as main ingredient, but I am not 100% about it. Not that flexible but also, if good quality and printed right it can be used for many years in different indoor environment. I use it for everything possible, and have been using for many years now. So far no parts had to be thrown away because of age. I also make some parts which are used on cameras and are parts of what I am selling globally. So far, nobody complained, so it seems to work everywhere between Australia and northern Canada, so I am happy using it. My printer is running almost every day, even at this moment.

PLA as mentioned is a very common filament used in FDM/FFM 3D printing of plastics. While the numbers look very good for biodegradability it actually requires specialized enezyme to get the best results. Other wise it is rather slow in degrading (think oak leaves and other durable starches. Depending on what is added to it can be rather strong and can be post processed with heat to cause further interlayer bonding as well as increase cross linakges of the polymers. Not UV stable but does have a rather slow UV degradation (Longer than Polypropylene plastics). Can be solvent smoothed with certain chemicals and as such is less tolerant than say the PET/CPE family. Can be made food safe.

Hope that gives a few better ideas on it. Used heavily in the miniature and modeling community as it is one of the cheapest filaments in the industry. Not considered an engineering material though.

Also having been one of those folks who bought a machine that did NOT use proper bearings (or even blocks to be honest). I can tell you the headaches from chasing down chatter, flex, runout and a mess of other issues is not something I would wish on anyone. That was a long time ago and I have a much better machine now that needs some servicing and new ballscrews on the X axis. That and doing some work preparing hopefully to move to the US.
