Speeding up start-of-print.

I'd like to make a request of Simplify3D that none of. the slicers I've used so far (intentionally ambiguous statement) have.

The option to change the heating/home ordering for efficiency.

Currently, it looks like: set bed temp ; wait for bed temp ; set extruder temp ; wait for extruder temp ; home.

Much faster would be: set bed temp ; set extruder temp ; home ; wait for bed temp ; wait for extruder temp.

Perhaps after the "home" one could raise Z by 40cm, so the operator can take care of any potential oozing as the extruder comes up to temp. Also, homing near the start avoids oozing over some random part of the build area.

You can already do this with Simplify3D. Your start script just needs to be edited to something like the following.

G28 ; home all axes
M140 S[bed0_temperature] ; begin heating bed
M104 S[extruder0_temperature] T0 ; begin heating extruder
M190 S[bed0_temperature] ; heat bed and wait to finish
M109 S[extruder0_temperature] T0 ; heat extruder and wait to finish
