SHAPEOKO 2 HUGE 3D MOD OVERHAUL UPDATE 4

SHAPEOKO 2 CONVERSION TO 3D 4 C

Still haven’t figured out a decent z-axis system. First iteration of the z-axis assembly had only one linear rail for the back and the front of the machine. This caused a unnecessary leverage effect that my diy PLA linear bearings would not be able to handle. Out and about town i saw two old hp printers for a euro each. They both had hefty 12.5mm 400mm linear rails. This awesome find lead me to incorporate them as 2 200mm linear rails per z-axis assembly. After designing a second iteration of the z-axis assembly which was a whole lot sturdier. But another problem arose from the depths. Since the glass build plate would rest on two z-axis assemblies it would cause the typical leveraging effect on the PLA linear bearings. So back to the drawing board! It then struck me, i am only using one of the x-axis linear rails of the two normally used. I can use the second one to brace the two sliding components of the z-axis assembly. Ill have to redo the z-axis assembly again, but its worth the extra structural integrity. That is all for now.
