Z motor bracket upgrade
I assembled the V2 with no problem. Very straight forward and enjoyable build.
All parts and sub assemblies are precisely prepared and wonderfully packed. Great kit and a great 3D printer!
However, I encountered one part that wasn't up to the overall standard.
The plastic bar that is used as a bracket to hold the Z motor to the Z upright rail isn't square.
As a result, the Z motor takes a small angle which puts the Z lead screw non parallel to the Z rail.
This could be fixed by some careful shimming but I decided to make an alternative bracket out of square aluminum stock.
This turned out great. I could now tighten the bracket screws as needed and the Z lead screw remained parallel to the Z rail..
Actually no CNC involved..
Stock 12mm square aluminum bar cut to size with a band saw,
Smoothed al surfaces on a bench belt sander,
Copied the holes locations and drilled on a basic drill press,
Countersunk 2 holes on the drill press,
Shaped the arc with a half round hand file, finished with fine grit sanding paper wrapped on a metal tube,
@Nid Neat. You probably have a CNC Router as i do not see any filed parts.
I was lucky as my 3Pro screws were parallel and there is no binding on the screw even with fully tightened screws on the z axis nut.
