    Trouble with circles in my code

    Fistly:
    Is mach3 demo version limited to the number of lines of gcode? this could be my problem.

    Heres the problem,

    I'm attempting to output gcode from Cambam which contains text surrounded by rectanular borders.
    cambam generates the toolpaths just fine.
    when I import the gcode into mach 3, the text gets garbled, usually some text is missing and there are large circles splattered all over.
    I have checked that the absolute and incremental modes match both programmes and that the post processor in Cambam is set to mach3.

    I'm realy frustrated by this as dozens of attempts have been tried with no sucsess.

    Many thanks for any help.

    Yes it is limited. Try your GCode in NCplot and see if you codes look right. It's a free back plotter (just click the NCPlot link under free tools).

    The large circles could be due to your IJ mode set wrong. G-code is limited to 500 lines. Everything after that is not displayed on the screen.

    Lots of circles

    Thanks guys, the IJ settings are correct, looks like it is the limitation of the 500 line thingy.

    Thanks
