There appears to be less of a blade sticking out of the holder than the MPM set up. Thats something we noticed recently. We have our mechanical attack angle set at 0 degrees right now, but we are in the process of changing this setting by 5 degrees t

Nice maCHEEN, mon. Please explain, �reliably dispensing�. What do you mean? How do measure? How are you sure? Etc. Just as points of reference: * What is the ratio of height to diameter of your dots? * How are you sure that you�re not stringing?
