V-Core 3.0 panels on 3.1¶
All but one of the existing panels for the V-Core 3.0 enclosure fit, without modification, on the 3.1 upgrade. The base panel needs to be modified as the Z-axis motor cages changed in design with 3.1. The existing 3.0 base panel requires 3 sections to be removed, and then a modified rear motor cage trim is used to cover the remaining hole.
Panel cutting template¶
The following PDF provides a printable template which can be used as a guide for removing the necessary material: by clicking here
Position the templates, and remove the marked material from the panel, as shown in the V-Core 3.0 to 3.1 upgrade guide
Rear motor cage trim¶
A modified trim for the rear lead screw motor cage is provided to cover the hole which remains when modifying a 3.0 base panel for 3.1. This replaces the stock lead_screw_motor_cage_back_trim_3.1 printed part
