Start Of Bar (Gripper End)

If the optimiser places a bar with a V notch close to the end at the gripper end of the bar, it can have detrimental effects

Modifications can be made to persuade the optimiser to move this piece to a different point on the bar

Machine	Limit	Photo	Effect	Solution
ZX3 / Microline / Flowline Mk3	<300mm		Gripper can hit ring when carrying out the reverse move on V notch cutting	Add mrdummy.x=-300 to V notch mnd files This will ensure a "minable" gap is always left at the gripper end to clear
ZX5	<250mm		V Notch could cut into gripper or X axis beam	The xholdpos will stop the V notch coming on if the x axis position is too low 4,-10000,820,OuB_VCut,True,X 8,-10000,1000,OuB_CLV,True,X A an extra precaution, the mnd file can contain a wait to ensure the Beam is in its home position (out of the machine) ;Ensure the beam is out of the way in.InC_BmPosH=1

End of Bar

Machine	Limit	Effect	Solution
ZX5		Depth will be inaccurate because the backfence is not particularly good in this area	Add mrdummy.x=-300 to V notch mnd files This will ensure a "maxable" gap is always left at the end of the bar and the V notch will be formed with a good backfence to reference and the V notch will be clamped securely from both sides
