Not like beef jerky, but still smoked

Last monday I've picked up from my university a package. It was filled wih goodies, 4 Nema17 stepper motors, 4 opto-endstops and a sanguinololu pcb with all the components... to solder on it!

So, on the next day I went to work and took the whole swag with me, hoping on having time to soldering everything while at work, and all went right, all morning surrounded by nasty fumes, but by lunch time I've already uploaded the Marlin firmware onto my freshly assembled sanguinololu and was able to connect it with ReplicatorG and PrintRun :)

But it was only lunch time, and when I got back at home, there was another surprise, my 12 "10€ worth ebay bought linear bearings" had arrived, oh happy happy joy (insert happy dance here).

Almost lost my bearings!

It has been a while from my last post, but let's get back to work!

Bearings... I went bearing shopping, at least get some ratings, and i was shocked!!!

I've asked on brick and mortar shops, and the prices... they asked me 4,50€ plus VAT for 1... yep, one 608 bearing!! 608zz are the same bearings you can find in skateboards, and not long ago I've built some longboards and there are top notch bearings in ceramic with ultra rolling power for 60€.... 8 of them!!!

And the cherry on top of the cake, linear bearings, lm8uu ones, 17€+VAT, also for one bearing... I'll be needing at least 11 of those!!!!

Well, I was getting disappointed, fired up a browser,, lm8uu, and bought 12 bearings for 10€...
