Move command has to adjust faster when changing input

When a print fails, you abort it, and then move lets say along the Z axis

and sadly you used the wrong direction / z value

the printer will move till the end of the first initially added value and does not adjust to distance adjustments.

for example this made my print head run into the print so I turned off the machine

this is quite silly that when setting the Z axis move to 50 mm but when changing it to -20 that the printer goes first to 50 and then to -20

so ideally the moment you change the move value the printer should use that!!!
