converting ms2 back to ms1

Postby turbotankshane » Tue Oct 17, 2017 8:35 pm

I purchased a v3.0 pcb that had been previously upgraded with the ms2 daughter card, but I opted to have it shipped to me with the ms1 cpu. The board had previously been modded for the ms2, and my searches are bringing up a little confusion. Are there mods that I need to undo to go back to the ms1 cpu?

Before powering it up, make sure there isn't a link from JS9 to 12v. This is for the stepper motor driver chip on the MS2 card, and is said to destroy an MS1.

I would ask just why you've opted for an obsolete MS1. An MS2 can do everything an MS1 can do, and more.
