It’s alive!
It’s very rewarding to see the motor moving 😊 Few issues though- it’s not a very linear response at all. I have a feeling that I need to make the step pulse train symmetrical high/low and just vary the frequency. The Trinamic driver I’m using has this feature called microplier where it interpolates input steps to output 256 micro steps for each input step (or 2 as that’s minimum input resolution I can chose without using serial interface) Nice feature as it makes the motor really smooth but it relies on reading last step period to calculate internal frequency so I think the fixed short pulse/ varying delay I’ve implemented is screwing its calculations up. Shouldn’t be too hard to convert my signal to a nice symmetrical pulse train though. I’m aiming for 1 revolution per second max speed which is plenty when driving the coarse knob of the Moonlite.
