Hi guys, just received my new Optimum BF30. I have a couple of questions for any one that owns this specific model.

I have stripped it down and cleaned all the grease off it and oiled the ways and adjusted the gibbs.

How do I tighten the bolts that hold the X axis lead nut down. I left them a tad loose so it didnt twist the ball screw, as there is no way to ensure the nut is parallel to the screw until you refit the bearings and plates on the ends.

Now I cant seem to get at the damn bolts to nip them up.:withstupid:

I also have 0.5mm of backlash at the moment. Is this to much to try and use the original lead screws to cnc with to get some plates made up first before going to ball screws?

Thanks in advance.
