Do this until the lines are completely closed If the lines are too thick and the material is really sweeping up then turn the wheel counter clockwise to lower the bed a bit The automatic homing of the bed and machine can also be changed with the bolt holding the Z axis homing on the front of the machine If the machine is always too high or too low then adjust the bolt by turning them In this way the homing is physically changed But always check the first layer to make sure After printing the machine will automatically cool of and lower and move the bed away from the extruder head Wait for the machine to cool off for a bit and than remove the printed object Reminder never touch the bed of extruder with bare hands Use pliers or tweezers for removing parts not manually otherwise you need to degrease again User manual Orca version 1 1 ORCABO 4 2 Replacing material If the spool with material is almost empty or when another material or color is wanted it is time to replace the spool Switch on the printer and run Printer interface Switch on the heater and wait till it has reached its temperature Try to leave min 1 cm filament sticking out After that reverse the extruder by turning on the big gear and remove the old filament which was in the extruder After that insert the new filament In case filament runs out during a print press Pause and unscrew the four bolts and remove the part in front

12. er the value the more the edge will be inset A ratio of one means the extrusion is a circle the default ratio of 1 8 means the extrusion is a wide oval This is an important value because if you are calibrating your machine you need to ensure that the speed of the head and the extrusion rate in combination produce a wall that is Layer Height Edge Width over Height wide To start with Edge Width over Height is probably best left at the default of 1 8 and the extrusion rate adjusted to give the correct calculated wall thickness Adjustment is in the Speed section with Feed Rate controlling speed of the head in X amp Y and Flow Rate Setting controlling the extrusion rate Initially it is probably easier to start adjusting the flow rate only a little at a time until you get a single filament of the correct width If you change too many parameters at once you can get in a right mess Feed Rate 16 mm s Defines the operating feed rate the speed your printing head moves in XY plane before any modifiers Flow Rate Setting 210 pre Skeinforge Defines the operating flow rate 40 see below for The default of 210 is for Skeinforge versions before 50 For Skeinforge 50 details and later set the Flow Rate Setting to the same value as the Feed Rate RapMan uses this parameter to define the RPM of the extruder motor The extruder motor RPM is flow rate 10 so if your flow rate is 150 0 that will set the extruder stepper to run at 15 RPM different print
