Comparison of Test results of Geometry
In Test 1 (with 2nd encoder):
Print 2 - Approximately 0-1.6% error per metre in geometry (Average 0.5%)
Print 3 - Approximately 0-1.4% error per metre in geometry (Average 0.7%)
Print 4 - Approximately 0-2.7% error per metre in geometry (Average 0.8%)
In Test 2 (only motor encoder):
Print 2 - Approximately 0-0.8% error per metre in geometry (Average 0.3%)
Print 3 - Approximately 0-2.3% error per metre in geometry (Average 0.7%)
Print 4 - Approximately 0-2.4% error per metre in geometry (Average 0.9%)
Test results show that with 2nd encoder, the geometry of the print is more accurate, but the print shape performance is not correct. This may be caused by tuning of the 2nd encoder responsiveness which causes additional oscilation movement (wavey) in print line. Further tuning could improve this.
Comparison of Test results of Print Speed
In Test 1 (with 2nd encoder)
All tests performed at same speed 4.5 m/min, which has oscillation wave pattern. As per prior comment we believe this is a result of the encoder tuning.:
In Test 2 (only motor encoder):
Print 1 - 6.3m/min was achievable
Print 2 - 9m/min was achievable
Print 3 - 7.2 m/min was achievable but at the limit
Print 4 - 7.2 m/min was achievable but at the limit
Print 5 - 9m/min was achievable
Print 6 - 9m/min was achievable
