300x200 Heated bed mount

Added Idler_mount v2. Initial issues with the original mount arose due to screw bending, which ultimately led to y-axis step loss. The new design accommodates a 20T GT2 pulley equipped with bearings and a 5mm bore.

A custom plate for the y-axis was designed to accommodate a 300x200 bed. In conjunction, the y-bearing holder was modified to support the new bed dimensions. Consequently, stepper and idler mount adjustments were necessary to fit the updated bearing holders. The original linear rail holders from the x-axis were reintroduced. This upgrade is still in development, but it appears promising so far. The plate thickness measures 4mm, while the bed thickness stands at 5mm. To facilitate the installation of bearings into their respective holders, a heat gun should be employed to warm them up. This will enable easy insertion with minimal force required.
