MB6HC - w/ TMC51xx or ? for HV

I'm sure it's not a simple hardware adjustment but I think it would be great to have the ability to supply high voltages to the board or a separate HV input for the drivers. The 5160 is good for 60v, the 5161, 40v and possibly another TMC option that could run up to 60v (probably require external MOSFETs). This would really help with the nema 23's. Pumping out high steps rates is not a problem so why not have the ability to significantly extend the RPM range of the motors while picking up the midrange? We all want to go as fast as possible atleast for non print moves and it would add more flexibility to a system that was designed to be flexible
@3dpmicro we are looking at extending the VIN range of the MB6HC and EXP3HC boards in future revisions.

@dc42 will there be a guide for adventurous people to do it themselves? or will it not be that simple

@luke-slaboratory there is some discussion of it here https://forum.duet3d.com/topic/14441/higher-input-voltages-for-steppers
