If you are using a NX post created using the post builder, open the post in the post builder. Go to the Program and Toolpath tab and select the Program Start Sequence in the left side window. Go to the right side window and see the Start of Program event that contains some block entries. Select the Mom_set_seq on and delete or remove it. Save the post and try it now. This should eliminate the sequence numbers.
If you do not have a NX Post, then go to the first operation and add an Start of Path command in the maching control tab. Sequence numbers needs to be set inactive.
Remember that the sequence numbers are used at the floor for restarting the program at a specific block and with this you will not longer have that option.
Hope this helps.
