Leonardo, How many defective motors do you have? Here's the link for the STMB motor drive. https://github.com/rene-dev/stmbl I don't recall the web site for the forum. Andy might have that handy. Might be worthwhile posting on that forum with the motor and encoder information. Someone is likely to have a spare STMBL they could let go if indeed it would solve your problem.. John
