You have your right to have any opinion, but I reserve my rights to disagree with that opinion. I was NOT the one who addressed him in a rude manner, I simply turned the mirror towards him and used the same language. :thumbdown:Quote:

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.
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.Quote:

Of course, this results in a few extra holes, but so what...Quote:

So far so good. What's funny is that the kit included four carriages. I have no idea how they are thinking... 200mm rails and four of those means basically no movement at all or maximum 46mm. I knew this when I ordered, I only need one on each rail, but this was the best price, so now I have two spares. BTW, even this BK feels fine to me, and I still think it is best to leave it as it is and replace the bearings with AC once these are worn out, if they ever will before I die or stop using it.
They suggest 250mm but went for the stock 300mm, I suppose better to have greater travel then less?Quote:

I will never need to make anything with 160mm diameter anyway. Initially it won't have any steppers on the axes, so no need for limit switch. My CNC Z has limit switches but only the upper one is ever triggered. That is different, there I have 160mm Z clearance and 140mm movement, so it is much larger and wider than this is going to be.Quote:
