The large M12 screw in the CNC-Fusion kit is probably the most annoying/difficult part to remove during the gib adjustment process as it is on the inside of the head. You have slide the head half way off the dovetail to get access to it. I noticed that the screw for the Z scale "needle" indicator (on the L/H side of the head) is exactly in line with the hole used by the M12 screw on the R/H side. As my mill is now CNC I don't need this indicator so I removed it, got a 12mm drill bit, and drilled out the existing hole (the casting is only about 5mm thick in this area). This allowed me to put a 120mm long M12 screw all the way through the head (inserted from the left hand side) giving me quick and easy access for future remove the Z ball screw assembly. Now at least all the screws are accessable from the outside of the mill (3 on the column bracket, 2 on the head block, and the M12 in its new position). |
Is this still working well for you??? I have to adjust my Gib on my Z-axis and am dreading the process...
