Who still uses Facebook anyways?
Received some nice things last week. New TIG-welder soon to be ready (only need Argon gas and a welding table), and I ordered some samples from Misumi for my upcoming printer build. I think I have finally found the perfect parts for Ultimaker style cartesian printers.
For prototypes, use BFLB8-15, which is a precision oil-free bushing. It fits PERFECTLY onto Misumi's G2 ground shafts (ideally SSFJ-8, the stainless steel variant. Because you need no oil). This is a very expensive part, because it has been pre-fitted and toleranced. You only need to stick it into a printed slider block and have great precision.
If you have the tools to drill holes into aluminum and hone them to h7 tolerance (Note: Those tools cost quite a bit, but it's not black magic or anything), you can buy an alternative bushing for 0.90 EUR which has the same precision once it has been fitted to such a precise mounting hole. So you can make a prototype with "no" tools, and then switch to series production - if you want to - and actually make a relatively cheap slider block with built-in high precision bushing.
/edit:
Oh, and of course be prepared to see a fully welded stainless steel printer frame

I hope I won't fk this up completely
