The BOOST input allows to manually reduce the current even while motor is rotating. This feature can be useful to reduce the heating when the whole torque supplied by the motor is not required (for example when the load moves at constant speed).

Yeah, but that will bring the motor closer to stalling, by a lot.

In other words, even doubling the current, a double torque is never obtained from a motor. For this reason it is usually superfluous to over supply the motor of more than 30% of the nominal current.

Oh i did try mine at 6m/s/s and the result was interesting to say the least, max velocity at 24m/m the machine started moving when changing direction, like the whole machine was moving a little (1 to 2cm) back and forth over the floor, everything was shaking and it did not last to do a video as it started ripping the teeth on the small belts ! Had to change both belts and set it back at 1.5m/s/s.
Thinking about it, the LAM version of lowering the current after acceleration seems very smart for plasma use, the biggest risk of stalling is while accelerating, so that makes sense. My idea of boosting current is much more suited for mills and stuff with bigger forces in use.
