Went I install my Z Tubing assembly on the Middle assembly, I install it with the lead screw nut on the bottom instead of it up on top ( Did not put enough attention on pictures ) However it does run good that way with no binding and turn really light by hand. Any logical raison way I should take it all apart just to reverse the nut location?
Also I have use the 300 mm T8 lead screw with 11 1/2 inch tubing for the Z assembly. At this point my lead screw is about 1 1/4 inch to long, should I make new tubing 12 3/4 ( which I do have ) plus it would give me more travel height, or cut off the T8 lead screw by 1 1/4 inches?
The machine is strongest with the shortest Z build. The way you have it no you can’t fully retract the Z axis and the screw sticking out means you can’t get close enough to your work piece. Basically you are artificially limiting your z axis throw.
The major problem is actual all the debris that will stick to your lubricated rod and eventually cause it to stick.
That was my first option, however the top flange do not have that insert cut out for the nut to fit in not much material shoulder either, so I decided to do it the right way and take the center section back off the tubing and re-install it the right way, will do a better job. It wasn’t as bad as I first taught, have it reverse already, just have to re-do the wiring.
