Skeinforge for RapMan

Draft

Some mission critical stuff is missing. For now, I just verify and edit the g-code, in particular to adapt the raft for larger pieces, or to slow down printing/augment extrusion rate for pieces that I want "smooth".

Introduction

Skeinforge is a tool chain for printing 3D objects.

The purpose of this entry is to write down the most important parameters and settings for the RapMan V3.1 as installed at TECFA (each Rapman may be a different)

Some parameters

Chamber

Turn off

Fill

Allows to define how an object should be filled.

• Default: OFF

Parameter	Explanation	Default	Comments
Solid Surface Thickness	Defines the number of solid layers that are at the bottom, top, plateaus and overhang	3

Fillet

Purpose: Rounding of corners

• Default: OFF

Flow

The flow script sets the flow rate by writing the M108 gcode.

Default: 210

Jitter

Jitter jitters the loop end position to a different place on each layer to prevent the a ridge from forming.

Raft

Raft is a script to create a raft, elevate the nozzle and set the temperature.

Parameter	Explanation	Default	Comments
Base Feed Rate Multiplier	Defines the base flow rate multiplier. The greater the 'Base Flow Rate Multiplier', the thicker the base, the lower the 'Base Flow Rate Multiplier', the thinner the base.	1	Maker it greater than the default

Speed

Speed is a script to set the feed rate, and flow rate.

Parameter	Explanation	Default	Comments
Add Flow Rate	Will add g-code	On	If nothing comes out of nozzle check this.
Feed Rate	Defines the feed rate for the shape	16 millimeters/second	seems a bit too much.
Flow Rate	Defines the operating flow rate	210	This may be too little. I often use 400
Perimeter	have higher build quality on the outside at the expense of slower build speed	0.5
Travail feed rate	Defines the feed rate when the extruder is off	16	slow down for figures with lots of little pieces.

Temperature

Parameter	Explanation	Default	Comments
Base Temperature	Base temperature	200	This is much too low
???	200	not enough
Object First Layer Infill Temperature	???	200
Object First Layer Perimeter Temperature	???	220
Object Next Layers Temperature	???	230
Support Layers Temperature	???	200
