OVB Block overlap in cutting feed
0: Blocks are not overlapped in cutting feed.
1: Blocks are overlapped in cutting feed.
Block overlap outputs the pulses remaining at the end of pulse
distribution in a block together with distribution pulses in the next
block. This eliminates changes in feedrates between blocks.
Block overlap is enabled when blocks containing G01, G02, or G03
are consecutively specified in G64 mode. If minute blocks, however,
are specified consecutively, overlap may not be performed.
The following pulses in block F2 are added to the pulses remaining at
the end of pulse distribution in block F1.
