Anet A4 Rods Improvement V2

thingiverse

This version changes from A4_Print_Plate_Improv_Adapter_R1.stl to A4_Print_Plate_Improv_Adapter_R3.stl. The change turns the magnetic link more robust. That feature improves structural instability observed in a few events while the car was equipped with A4_Print_Plate_Improv_Adapter_R1.stl geometry. These advert events happened while the printer was printing, in all of these events the car was near the edge of the bed. Robustness checks shown poor transfer of magnetic force to the rods when these rods were almost horizontal-aligned. In order to improve the magnetic force transfer to that design weak point, the magnets orientation were optimized and became aligned to the rod when the car lays in the middle of the bed. Kindly refer to "Anet A4 Rods Improvement" in order to collect the remaining geometries (A4_Improved_Car_Ball_Joint.stl and A4_Axis_Ball_Joint_Improv_Adapter_R1) that were kept unchanged. A fine tuning on the EEPROM was needed. The Radius get reduced after such update in 2.6 mm. The Height get reduced as well in 1.3 mm. So, after replacing the printer with these brand new mechanical parts, The final sizes that matched satisfactory bed leveling over the 200 mm diameter bed was: Diagonal_Rod = 208 mm Radius = 100.12 mm Height: 207.56 mm
