Definition and use of the yNotchStartGap parmeter|
Applies to machines with V notching on the ring - worse if the blade size is 200mm
If a Y notch is at the very start of the bar, there is a combination of the gripper location inside the ring with the Y and Z axes in an extrreme position. This leads to a clash between the gripper and the ring.
Original solution was to build a big "minable" into the gaps.saw file to force a big waste cut at the beginning of the bar. This was done by specifying a gap of "s+s" (minable+minable) or "s+s+s" (minable+minable+minable).
This is a bit cumbersome, and there are downsides to it when using it on a Microline becasue this amount needs to be reflected in the mnd files used to control the saw blade - W_ESYF.mnd and W_ESYR.mnd
From software version 126.96.36.199 a new parameter was introduced, specifically for this purpose - YNotchStartGap. This is normally set at a value of 270 for a Microline or ZX3
This allows the variable to be used in the mnd files
The gaps file calls on this with the variable "y"
