92 forum posts 12 photos	Having owned my SX3 mill for nearly a year I'm finally getting around to fitting the DRO which has been living under my bed for the last six months. I'm fitting the Z-axis strip and read head inside the column so have taken off the rear cover for access and find it filthy inside: remnants of casting sand, dust and grit. It's also obvious that the Z-axis lead screw and nut and the bevel gears are not, and never have been, lubricated - I'm assuming that they should be, so what with? I've some 'general purpose' and some 'high performance' lithium based grease in stock - would these do? This makes me wonder of the thrust bearing has been packed as I suppose it might perhaps not have been - but the dismantling required to check this would be in a whole different league.
