Hi Guys,

I've being messing arround with SolidCam and Mach3 for some time now and today i'd first tried an Helical finish on my part to see if it would be better finished but i've a problem here.

At begining of the path the helical won't disappear so it looks like on the attached photo.

Firts i thought: Well the freakin part moved and the mill hadn't passed on the first cut area so i made a new tool path declaring an 3.7mm end mill and used a 4mm so it would cut 0.15mm on the part but it did se same thing! Cutted 0.15 all arround but didn't remove or reduced the deffect! the problem it's only there on start...

any ideas?
