Hello everyone, can someone explain me how to make multiply passes ? I import files from dxf to nc plot, and there i can enable or disable layers which is very good,but i need multiply passes when making holes, somehow after one pass to make z deeper and so on until make hole. I have cnc for engraving aluminium  and i will appreciate  all kind of help because am new on this   . Thanks a lot !

Don,t know how to tell you to do it but what you are asking is peck drilling cycle (I know just about enough to get me into trouble)

Just to inform all that i found what i need, in nc plot there is option " increment of z depth" there you can input how much z axis will go deep in every new pass until reach " z depth" which you can also define. Hope it will be useful for someone !!!
