Prusa I3 - Y-Carriage Reworked

thingiverse

I've discovered that much of the unwanted jerk wobble in printing at higher accelerations is caused by the acrylic y-carriage vibrating when the y-axis movement changes direction. To resolve this, I came up with an idea where I realized that placing the bearings so far from the bed level screw holes allowed the carriage to vibrate up and down. So, I designed a new y-carriage where bearings were placed as close to the bed level holes making it almost impossible for the bed to vibrate up and down during sudden movement changes. I also utilized four bearings instead of three, securing all four corners of the bed with maximum stability. Furthermore, the bed height is 8mm with very tightly fitting screw holes that match M2 screws precisely, keeping the screws extremely stable within the carriage. Please note: The RadialBearingHolder file can be used to create custom-made bearings using 623ZZ radial bearings, and it has performed amazingly well for my setup in terms of rapid printing, high precision, and increased acceleration. Print Settings: Printer Brand: RepRap Printer: PLA Supports: Yes Resolution: 0.3mm Infill: 10% Notes: Print as desired because this setup must provide stability so I've printed it with four perimeters for security.
