Cura has come quite far since the early days, now rivaling S3D for the crown of 3D slicers. With many experimental features, along with massive support from the community, Cura is a world-class slicer, and best of all, it's completely free. Cura is a great option when you're a bit more advanced with your prints.
Simplify3D continues to prove itself as one of the best slicer engines on the market -- as one of the few premium (paid) slicers, it has certain features that make it better for many parts, whether that be the multi-process capabilities, or simply the way it decides to make the toolpath for different geometry, we love, and generally opt for using S3D.
INTAMSUITE is the slicing software released by Intamsys for the Funmat line of printers. Based on Cura 1.6, it comes with preset profiles for PEEK, PEI, PPSU and other high-temp materials, set up for the Funmat 3D Printers. It's a great way to get started, but you'll want to copy profiles and upgrade to Cura or S3D for advanced prints.
G28 ; home all axes
; include G29 to autolevel REMOVE AS NEEDED
; include M141 S90 to turn chamber to 90C MODIFY OR REMOVE as needed
M300 S440 P5000;
G92 E0 ; set current extruder position as 0 so that E15 below makes sense
G1 X10 Y-100 Z0.2 F2400.0 ; move to just on the bed
G1 X10 Y70 E15 F1200.000 ; extrude a line of filament along the right edge of the bed
G92 E0 ; set E to 0 again because the slicer's next extrusion is relative to this
M104 S0 ; turn off extruder
G91 ;relative positioning
G1 E-1 F300 ;retract the filament a bit
G1 Z+2 E-5 X-20 Y-20 F2000 ; move Z up a bit and retract filament even more
G28 X0 Y0 ; move X/Y to min endstops
M84 ; steppers off
