I have a question regarding the PolouPres_V3.pdf that explains how to calibrate the A4988. First let me just say thanks for the doc
I’m confused as to where I put the multimeter. I’ve created a diagram to show what I think the pdf means. Could someone confirm that this is correct (or wrong!)?
I also have another question. I think I know what the answer will be ad I feel very stupid, but I connected the 12volt power with the polarity the wrong way around. Will that ruin the A4988?
Thanks for any help.
