Y Motor Voltage on X-Controller

I’m wondering if the Y current control trimpot should be set for double the voltage when using seperate Y1 and Y2 motors on the x-controller?

Cool, thanks! I only ask as they are making what sound to me as stalling type sounds, very different to the X axis. Is this normal?

Edit: Although the cuts seem reasonably accurate…

“Stalling sound” is a symptom that should be treated IMO.
