- Sep 7, 2009Is the top speed the same as the rapid movement speed? If it is slower then low voltage to the pot is the most likely reason for the problems.

A dirty/poor connection could cause this. Is the top speed the same as the fast traverse you get from the button on the power feed? (I am making the assumption that there is one!) If there is a big difference in top speed and fast traverse I would be looking for the cause of the loss of voltage to the pot.
