Metal Shaft of X and Y axis is not compatible with Plastic
Shaft. Plastic Shaft is slightly different in size with Metal shaft. Due to
different size, it needs to adjust the four corner shaft position and X axes
rods which are complicated. Its reason we do not recommend to replace metal
shaft to plastic shaft.
