I bought an aluminium metal x-carriage from aliexpress. This part allows better prints and is adjustable also. lso. The extruder is E3d V6 short distance for 1.75 filament with 0.4 steel nozzle. The fan is 50 mm radial holding my nozzle duct.
I have made a revision on the metal carriage. Unscrewed the motor holder and reversed it. Then the motor is at the right side and the nozzle is more to the left side. So I am able to move the extruder and the nozzle more to the left allowing it to travel all the way on the construction bed. Otherwise, the nozzle cannot reach to the zero point.
