MKS SBase and Smoother Case for 2020 2040 Extrusion

thingiverse

This case supports the MKS SBase (v1.3) controller, which features mounting locations for MKS Smoothers and an optional 120mm fan. * The MKS SBase is considered a problematic board by Smoothieware. If you purchase this board, consider supporting the project in some way. * Although external drivers can be used, the SBase includes DRV8825 drivers that have issues with microsteps. These problems can be addressed at 12V using 8 diodes per motor, and this case features mounting locations for up to 5 MKS Smoother diode boards. At 24V, you would need 16 diodes per motor, making external drivers a better option. However, TMC drivers are on the way for a 24V setup, and adapters will be designed so they can use the diode mount points in the future. Enabling fast decay is another option, but it's not optimal due to its noisy nature and requirement of very fine soldering work. * One wall has been thickened and includes holes for M5 (10mm) bolts to attach to popular extrusion profiles like 2020 and 2040. * The first image shows the Z-axis motor jumpered to the E1 motor, allowing for synchronously driving two Z-axis motors at full power. * The extra room is intended for holding extra wires, DC-DC converters or whatever else can fit in the space.
