Hi, I have NEMA 16 motor and I connected it to A4988 so I can control the motor to arduino. The problem is that there is a trimpod in the drive A4988 and many people say I should first set a precise current using the trimpod to avoid damaging the module.
I saw many tutorials online and they look too complicated and I dont even have a multimeter. So my idea is this: could you please tell me which wise (clockwise or anticlockwise) the trimpod reduce and increase current?
My idea is this: I will turn the trimpod in the clockwise/anticlockwise many times so I decrease the current to a minimmum. After that I will turn on the motor and see if it spins. If it does not, I will turn the trimpod and increase the current till it starts moving so I know I am not abusing the current.
But first I need to know: do I need to turn the trimpod clockwise or anticlockwise in order to make this module A4988 have the minnimum amount of current?
