Extruder vref adjustment (MK3S+)
I need to bump up my Extruder vref a bit, is there a command in gcode that will enable this, or do I need to go on to the motherboard and adjust a trim pot?

The motor current is set by the firmware directly to the drivers. You might be able to change tha by M906 or M907. But I highly doubt that it solves whatever your problem is. Please look for actual mechanical issues first - setting the current higher might easily destroy your motherboard and / or the motor.
When you have extrusion problems, not enough torque in the extruder stepper motor is not your problem.

Thank you @hli, I am not having any kind of extrusion issue, I need to run two stepper motors. I assume I need to up the vref a bit to compensate for the second stepper.
