COREXY 3D Printer - Z Axis Upgrade
Z Axis Upgrade to V Slot
The Standard soluiton of 8mm smooth rods and bearings is ok. But it can be a little squeeky and jerky as time goes on.
The following upgrade will eliminate that problem making a much smoother Z axis mechanism. With this upgrade I was able to up the maximum Z axis speed on the printer from 300mm/s to 700mm/s.
6x POM Guide Wheels (per side) = 12 total
6x M5x40 Bolts (per side) = 12 Total
6x M5 safety nylon locking nuts (per side) = 12 Total
6x M5 washers (between the 3D printed part and the wheels) = 12 Total
If your printer is too small to make this part it can be ordered in my online shop here.
The 2020 or 2040 Alu V slot Profile to create the Z Axis rail can be screwed to the frame from the top and bottom, or clamped using 3D printed L 2020 angle brackets or using metal 2020 profile brackets.
