Hi Derek,
Great pictorial! I have two questions...
1) What is this product and where to get it
"self adhesive film "
2) I notice this is a servo control being built, can you share some
details about this? The reason I ask is that I am about to convert
a machine over to CNC using servos. I have not yet purchased the
servo drivers yet, so I am curious.
