The ultimaker style gantry had racking problems if the cables weren’t perfectly tensioned. Many methods were tried to make a easy way of tensioning the belts. It was decided to just design a simpler xy gantry.
The y axis is positioned using the belt system on both side using the rotating shafts with the pulleys.
From this picture you can see the fan duct cooling system which will blow air to cool parts.
Newly designed upper z axis linear shaft mount with 608 bearing mounting to centre the leadscrew. A adjustable endstop mount attached to the shaft.
