Okay,

Ordering the 2 - 12m anti backlash nuts from Dumpster. One for the 12mm on X axis and one for the Y axis. Looking at getting a piece of 12 Aluminium to go across the gantry to add a bit of ridgeness and boring out the section of Z axis that rides on Y so that it will accept 16x20x30 mm Oilite bushings to it and most likely do the same to the bushings on the Z itself to get less flex and better wear as the current bushings are looking to need replacing and with less then 300 hours cutting time on the machine, I think upgrading if possible would be the wise way to go. Only need to drill out the 30x120 extrusion to accept the new bushings.

Also putting in new Bearings on the end and switching to stainless steel with rubber seals and see how that goes. Still working on the new machine and have bought the Z ball screw from Gary at Zap and just need to earn the rest of the money to buy the parts (also need to draw up my ideas and let you folks have a field day with them).

Anyway take care folks and have a great day. More information as it happens.
