First I will say I think it is your post because I used the default 4th Axis post & got the same code Mike got. Having said that, go to your Operation Navigator, Right click on 4th axis & pick Edit\ Internal_Trim box -click Start/ End Events\ Machine Control box appears- check Start Events & open Edit \ User Defined Events box appears\ Highlight Set Modes- Click add\ Set Modes box appears\ under Arc Mode , change to circular & make any other changes that apply , & play. I hope this help's . Harold C
