3.1 Printer Profile

For normal prints, use the X1C Daily profile. This is dimension-corrected.

X1C Daily	Daily use
X1C Strength	More wall loops, denser infill
X1C Random-Z	Strength with random-z seam

4. Printing

4.1 Before printing

When using cold plate

• Remove the plate from the printer.

• Apply glue to the print area.

• Put the plate back to the printer. Make sure the edge of the plate is aligned to the guides on the printer.

When using engineering plate

• Remove the plate from the printer.

• WARNING: Make sure that the cold plate side is free of glue.

• Put the plate back to the printer. Make sure the edge of the plate is aligned to the guides on the printer.

4.2 Load filament

The AMS should auto-load the selected filament.

PLA (AMS slot 0) is recommended for normal prints.

PLA-Tough (AMS slot 1) is recommended for mechanical parts.

PC (AMS slot 2) is used for transparent parts.

Sup.PLA (AMS slot 3) is used for breakaway supports for PLA.

4.? After printing

When using cold plate

• Remove the plate from the printer.

• Slowly lift the part from the build plate. Bending the plate a bit might help to detach.

• Remove the test extrusion patterns on the edge of the plate.

  • There are two test extrusion areas, one is near the bottom of the plate, and the other is near the top right corner of the plate.

• Observe the glue film status and re-apply the glue to the part adhesion area. If there is too much wear, wash the plate thoroughly with fresh water and re-apply the glue.

5. CAD design considerations

Recommend to use OnShape for modeling.
