table moves the rails up to print height, printing takes place.
The top plate of the rear OTC can swivel to accommodate snugging of
boards that do not have parallel sides. In the plan view above, the board is
shown with the snugger clamp against its non parallel surface; when the
OTC moves in to position the swivel plate conforms to the snugger.

Unclamping There are two unclamping states, there is unclamping with the board retained
by the OTC plate and unclamping with the board released. The two modes of
operation are programmed via the software. The parameter, OTS Retain Mode,

print. This is the default setting.
