Darwin's X axis repeatability
Appologies, this has been a bit slow coming - I've had the lurg. The final repeatability test for Darwin: here we're looking at the performance of the x-axis after mouding a gear diectly on to the motor (see the previous "Darwin's X-axis toothed pulley" post). Results are, again, looking promising with repeatability to ±0.025. Again, a further test is needed at a later date to understand how asymptotic the trends are, but as with the other two axes, we're in the right ball park here.

awesome! so does that mean you're ready to print off a set of test parts for me? ;)
ReplyDeleteoh, also... i noticed that on this one there is a trend toward being more reliable at the end... have you tried doing a longer set of runs? i dont know how intensive it is to record the data and set this up, but it would be nice to see if that trend holds up in the long term. if so, it looks as if it is +/- 0.01mm which would really rock.

ReplyDeleteHaha! Doesn't seem far off...
> have you tried doing a longer set of runs?
Definitely on the menu, but something to look at after the release I reckon.
