（1）Repair
Merge Open Segments of Model Parts means merging the non-closed polygons in the model parts.
Merge Internal Overlapping Parts means merging the parts which are overlapped in interior of the model.
（2）Thin Wall
Check Thin Wall (Single Extrusion Width) means that check if the width of the model parts is less than the defined thin wall width and extrude one single extrusion width to instead.
Minimal Extrusion Width Percentage refers to the minimal percentage of extrusion width. Maximum Extrusion Width Percentage refers to the maximum percentage of extrusion width.
For Example, if the extrusion width is 0.4mm, set Minimal Extrusion Width Percentage to be 25% then the minimal thin wall will be 0.1mm. Set Maximum Extrusion Width Percentage to be 200%, then the minimal thin wall will be 0.8mm.
If item’s width is less than 0.1mm, it will print nothing as the width has less than minimal extrusion width. If item’s width is larger than 0.1mm, but less than 0.8mm, the system will extrude one single extrusion path instead. And the width of the single path will be adapted to the size of space dynamically.
（3）Gap Filling
Fill Gaps in shells refers that with this function enabled, there will no gaps between shells as Figure 5.83 and 5.84.
Gap Fill Speed refers to the speed of printing the gap filling.
Allow Filling Gaps using Single Extrusion Filling refers that with this function enabled the gap will be filled by single extrusion filling.
Minimal Single Extrusion Width Percentage refers to the minimal percentage of single extrusion width.
Maximum Single Extrusion Width Percentage refers to the maximum percentage of single extrusion width.
For example: if the extrusion width is 0.4mm, set the minimal singe extrusion width percentage to be 50%, which means the single extrusion width is 0.2mm. Set the maximum singe extrusion width percentage to be 200%, which means the maximum single extrusion width is 0.8mm. If the gap is less than 0.2mm, it will not be filled. If the gap is larger than 0.2mm and less than 0.8mm, it will be printed by single extrusion filling. And the width of the single extrusion filling will be adapted to the size of space dynamically.

（4）Pause at Height
Pause at Height means that the printer will automatically suspend a print job at the defined height. You can do several operations such as changing filament and resume the print then.
You can define the height by clicking the Add Pause Point button. And delete the defined height by selecting the value in right box and clicking the Remove Pause Point button.
Note: This height doesn’t include Raft.
（5）Bridging
Extrusion Width Percentage refers to the percentage of bridging extrusion width. For Example, if the extrusion width is 0.4 mm and you set this value to be 120% then the bridging structures extrusion width will be 0.48 mm.
Bridging Speed refers to the speed of printing the bridging.
Enable Bridging Fan Speed refers that with this function enabled the fan speed of bridging can be modified.
Enable Fixed Bridging Angle refers that with this function enabled the fill lines angle of bridging structures will be fixed as the value you set.
Minimal Allowed Bridging Area refers that if the overhang area is less than the value you set, the system will recognize that it is not bridging structure.
（6）Global Offset
Global Offset means that means you can apply X/Y/Z offset to all coordinates in the gcodes.
You can separately set X-Offset, Y-Offset and Z-Offset.
