Just wondering as well, the servo in this link, would it be worth changing this unit to see if it helped the issue? As part of a smaller, less expensive gamble to sort it? Still trying to establish a list of smaller, less expensive avenues to explore before anybody has to resign themselves to buying the dearer full columns.
Should maybe call them before buying and clarifying as they say:
Item description:
