I want to use the machine as a fine wire coil winder (to make guitar
pickups). I need high resolution on the traverse (pen) motor but speed
on the other motor. I believe the latest version of the EiBotBoard
uses the same microstepping setting on both motors. For my applicaton
microstepping for the pen motor has to be at least 8X (without having
to gear the motor down), but full step for the other motor would be
ideal and speed things up greatly. That is the reason I decided to try
the EasyDrivers for the time being.
With the EiBotBoard I tried increasing the speed until I reached a
point where the motors stalled at around 5 rotations per second, I
wonder if I was hitting a limit with the power supply (I was using the
original Egg-Bot for these tests)? Perhaps I should go back and
experiment some more.
Another issue I found was the limit of 32,000 steps per move. For my
application I need to wind around 8,000 turns of wire (diameter around
0.063mm) across a 12mm wide bobbin - so to just to wind a single layer
across the bobbin requires lots of separate moves.
There are much simpler ways of winding guitar pickups, but they
wouldn't be half as fun or educational!
