Good morning guys, i sa[l]vaged a captive linear actuator, tried moving it with easy driver, but i have several problems.
The actuator is a bipolar motor with step angle of 15°, winding voltage of 5v@250mA /12v@100mA.
It should work with 2.5W
When i tried using easydriver, it makes some noise, but does not move. I tried changing all the settings, reducing and increasing the delay from one step to another, going from half step to full step, it moved only once, wobbled a bit, then moved no more.
I already switched from the arduino Voltage Output to an external 12v power supply.
There are chances that i connected the pins of the motor incorrectly, and the easystepper does get hot
I managed to move it, after moving a bit manually (it seems that sometimes it gets stuck at the end or at the start of the shaft), and by putting MS1 on HIGH and MS2 on LOW, so half step mode. I also tried all the possible combination of pins, probably i missed the only working one (don't know, guys)
I managed to make it move even with steps at 900microseconds. If i go at 800 it goes wobbly again (i know it could be faster, that's why i tried 800microseconds, so i tried)
Now i'll try to power from the arduino board.
I have to ask you a question: since i noticed some grease leaking from the shaft, could it be that it lost some lubricant, so it gets stuck?
