Things that small which weigh the same as a small car tend to NOT shimmy.!!. . . . . . They just try to TIP the shed over.:dance:

When you do get the X axis going don't try going straight to 5mtr/min, twin screws setups tend to need a slight safety margin to be sure one motor doesn't stall which can really screw the gantry up bad.
With 5mm pitch screws your near max rpm and less torque, your gantry ain't over heavy but it ain't light weight either so tread carefull when your approaching 5mtr/min. If you don't need 5mtr/min then I'd say back it off just for good measure.!
