    Hi All,

    I moved to New Zealand 5 years ago. My belongings inc my CNC router only arrived recently . Now I'm set up again but totally out of practice and forgot a lot that I need to teach myself again. I was no expert to begin with but Ok for being self taught.

    I run Mach3 .Version R3.043.062 I have an issue I remember having last time I used it that I need to sort before I start again. Maybe simple ?.

    In the middle of milling product, if I notice something is not quite right with the toolpath or I need to pause the program momentarily, I use FeedHold. As I understand it, after I want to continue the process I press Cycle start again. But then something disastrous happens and the spindle moves or jumps to a different part of the nc file and the tool crashes into the vice or other part of the product . Un-related to where it was left off. Maybe I have a setting in Mach3 ticked or un-ticked that is causing this?

    Also another small issue was my nc file and mach3 had conflicting Safe Z points. What is the simplest way to keep this a standard ? Keep the Safe Z dictated in Mach3 or in the .nc file ?

    Not sure if this may be of any benefit for you but when I cycle hold I always restart it from a known safe point such as a straight line or Safe z so I know it wont plunge into stock by accident. A pain but I think there is a better work around from the more knowledgeable wizards on here!
