    Engraving tootpaths.

    I'm a new user for Mastercam 2019. I tried to engrave some letters and numbers but a message showed up on my screen saying it was invalid " Open chains are ignored. return to continue." as well as " No valid chains found. Please select closed chain(s) for contour." Please send instructions to help me solve this issue. Thank you.

    Re: Engraving tootpaths.

    I am guessing that the letters and numbers are composed of individual lines and curves.You need them to be joined as chains for each character.You might get away with a box selection process and the machine might then engrave each element in some order.It might take less time to analyse the area for broken chains and then join them.As a new user I would be on the phone to the people who sold me the program as the normal training package seems to have left some gaps.

    Re: Engraving tootpaths.

    did you draw the text or was it from a cad model
    if it is the cad model then look to see if it is a true font single line there maybe extra lines that mastercam doesn't like for engraving
    i also use contour instead of the engraving feature this seams to make a lot less moves just remember to put the cutter comp to off
