    @cmcgrath5035 & @alden – thanks for the replies.

    Apologies for not replying sooner; other projects got in the way. Plan to get back to this over the weekend.

    I’m using CamBam to generate my G-Code, and OpenSCAM as my viewer.

    Both of these previewed the files ok.


    @cmcgrath5035     – interesting that other CAD/CAM packages are mis-interpreting the files as well. Wonder if CAMBAM is doing something that is either ambiguous or complex to correctly implement in the G-Code spec.

    (I don’t use CP very much… at time of purchase I wanted to set up my small CNC like my 3D printers, driven by a Raspberry Pi class machine, vetted TGFX and then ordered the machine. To have TGFX dropped by the time the hardware arrived, and CP is a PIA to use on lower powered machines- and not particularly ‘safe’; there can be terrible lag in the UI and it’s difficult to get it to reliably pause quickly.)

    Let me know if there’s anything I can do to help track down this bug!

    Cheers,

    Julian

    I’m seeing the same problems- really good description HCamp!

    Here’s a photo of the results (stopped as soon as I heard it cutting through the clamping wood): messed up arcs

    And the G-Code generated by CamBam that caused this:

    To be clear- the circles carved are not supposed to be there!

    I’m on the latest firmware, and checked $CT; it’s set to the recommended default.

    I’m switching to use line segments and not arcs; fingers crossed that will work with ChilliPepper on a Raspberry Pi…

    Really hoping TinyG gets these bugs ironed out soon- I love the potential, but it’s driving me nuts!
