Let's break down the part rationale. These are weird choices for weird reasons but overall they will work in this case.

1. The electronics are being switched to 24V. This is so I can run the stepper motors quieter and faster, as well as running a heated bed with a much faster heatup time.
2. The electronics are extremely rudimentary, but I'm okay with that. If any complex issues arise, I have no problem swapping to an MKS board.
3. The TMC2130 drivers are used for a niche feature: endstop-less homing. Weirdly enough, the Replicator does not actually come with endstops; it relies on measuring back EMF to see whether or not the motors are on a hard endstop.
4. Yes, the Titan Aero is a very expensive part, and I definitely could have used the money better elsewhere. However, with the extra Z-height, flexible performance, and compact package it gives, I don't have to worry about retrofitting an extruder assembly into an already weird mounting area.
5. The 10mm linear bearings will be used to upgrade the bed: I am planning on making a new bed assembly to use instead of the original Z-axis.
