DIY Build of Aluminium CNC Wood Router without Workshop & Tools

[WandrinAndy]

No probsh... My confusion was caused by me not realising the blocks come in that many different models.

Two quick questions please.... I'm considering again how prone the ballscrews and profile-rails are to contamination from chips etc. particularly on the X-Axis.

I'm guessing it might be prudent to get the optional bearing-block scrapers fitted to protect the seals on the X-axis, but that the other axes are far enough removed from the cutting point to not be too much of a worry?

Let's say I am machining small alu parts... would this be best done at the BF end for better accessibility and to reduce contamination, or best at the BK end that is closer to the motor?

Thanks,
Andy
