I've implemented a pick and place using Nodejs and Smoothie.
Everything works great placing small parts (1.9mmx1.2mm), but bigger parts (12.7mm x 12.7mm) get jolted by the acceleration.

I would like to set acceleration differently based on the size of the part.
This needs to take effect quickly so different parts can be placed.
M204 S2000 sets acceleration to 2000 ( it takes a few seconds for this to take effect after the command is sent ).
A few seconds is too long. Is there any way to change this for the next Gcode?

John
