![]() ![]() The above only applies if the motor is in FULL STEP mode. It doesn't matter what the sequence is to start with, as long as the sequence CHANGES at each step application in the order shown then the motor will move. The next pulse should change it to 0, 1, 1, 0 and the next pulse should change it to 0, 0, 1, 1. ![]() If, for example, the motor is 'still' and you measure 1, 0, 0, 1 at D2-D5 then apply ONE pulse, the sequence should change to 1, 1, 0, 0. On the chart I showed the labels A, B, C and D correspond to your D2, D3, D4 and D5 (or D8, D9, D10 and D11) and the steps 1-4 are the logic levels for one-thru-four applied pulses (steps). They will be either 0V or 5V (give or take a tenth or two) so the 0.13 (or 0.1) should be noted as '0' and the 4.83 noted as '1'. If you apply ONE PULSE to either the up/down motor OR the left/right motor then the conditions at D2-D5 or the conditions at D8-D11 will change. Your list should only show D2-D5 and D8-D11. One motor controls up/down, the other motor the left/right motion. In 'full step' mode these voltages should be around +5V and 0V (which is what you have for D8-D11). Are you microstepping or are the motors driven as 'full step'? Can you switch between the two?ĭ10 and D11 seem much more like what I'd expect.
