Rather than inserting a "/" and removing the G00 from the format as you seem tobe doing currently , change the G00 variable as the posti designed to format, it insures 100% seemless posting.
From ther Posting Format Dialogue Box Choose -> Rapid Line Format from the Drop Down Menu.
On the right side are the available Insertions and Substitutions for that cycle. Select the - G00 Rapid Move and below will appear the current Rapid Line Variable Prefix. Repalce the G00 Value with the '/" character you require and click OK.
This is proper method.
