Calibration

This chapter describes how to calibrate your dual extrusion printer and describes additional steps to make a
dual extrusion print.
Calibration is only necessary when you have purchased a DIY kit. For the assembled printers, the
calibration is already done during production. Only when you exchange a hot-end, re-calibration is then
recommended.
Assumed in the following steps is that repetier-host is already installed, that the hot-ends are calibrated
correctly to have the same height and that you just finished assembling your DIY kit.
1. Make sure you have the latest dual extrusion firmware loaded. Download it here

2. Prepare the Repetier-Host interface for dual extrusion.
Select your printer
3. Print test_thinwall_v3.gcode with extruder 1.
a. Go to repetier interface and select extruder 1. Heat up extruder and heated bed.
b. Printed output must show a smooth straight wall. Possible issues:
-
Wall is not straight. Check if hot-end is correctly fastened. Check if pulley is fixed correctly on
motor axis
-
Gaps in part. Make sure the extruder arm exerts enough tension on filament. When extruding
manually, it should be very hard to hold back the filament by hand.
