Are you referring to the motor shield that you have burnt with a chain wrap mentioned in this post?

If so, what happened to the shield that you said was ‘on route’?
I don’t think you can instruct someone willing to send you a free replacement part for something you broke yourself. You can request it and offer to pay for the huge shipping cost cross country couriers ask for.
Lets forget for the moment, that it’s strange to post the way you did in a Forum with hundreds of users that have witnessed how exceptionally great Maslow service was the past 2 years. Lets also forget for a second that insulting with ‘taste of blackmailing’ will not get you anywhere else then on a spam list and being completely ignored.
Maslow has retired from supplying hardware Aug/Sep 2018 and would expect them to have no more parts to replace. They gave their stuff to https://maslowsurplusparts.com/
Plenty of forum users around the world have received motor shields and other parts from other members for free. Their success was the result of a friendly and respectful approach.
