Need help selecting a Spindle and VFD

Hi all,
I am completely new to this as you can probably tell. I recently bought an old Gerber Dimension 200 for cheap. It’s a beefy chassis that will allow for a great machine by doing some upgrades. I’m doing a complete overhaul of electronics, spindle, steppers, limit switches etc. All of which will be run off a 7i96 board with the SpinX1. I am a bit confused on how to choose a spindle. I’d like it to integrate with the Mesa board well obviously. The wiring just doesn’t make sense to me on what goes where. If anyone has a solid recommendation for a spindle kit or the like please let me know. Will only be doing wood and aluminum, with the occasional steel sheet. Thank you guys for your time and knowledge.

A D-200 would have come with a 3hp Porter Cable router or the optional engraver head. Either way you will need to fabricate mounts for what ever spindle you choose to get. The D-200 is also very limited in vertical travel so you will be limited to mostly sheet material. These machines were made for primarily for sign making and are really just suitable for milling wood and light aluminum, They are quite light compared to a real metal working milling machine.

You might be able to make an adapter sleeve to fit the common 80mm diameter 2.2kw spindles sold on ebay and elsewhere to fit the 4.2inch hole for the Porter Cable router.
