    Hi Guys,

    I have a machine that is set up. It jogs on all axes for coolterm and from chilipeppr.

    I’m having a problem where the machine is not at all following the file I’m sending to it (or at least, its not at all doing what the chilipeppr simulator and meshcam think it should be doing). The exact same problem happens when the file is sent via chilipeppr and coolterm.

    Can someone help me troubleshoot?

    This is what is happening: https://www.youtube.com/watch?v=Q8SFJcrQC-g
    This is what it ‘should’ do: https://www.youtube.com/watch?v=PVLrubAIGz4

    This is the nc file, generated in meshcam: https://drive.google.com/file/d/0B7T5Ozph1ofAVVl0bWRSajBRUms/view?usp=sharing

    Help, I’m at a loss!

    In case its not clear from the video – the tool should be making a circular path and slowly expanding so as to “spiral” out from a central point. Instead, the toolpath makes a semi-circle path then reverses direction, then comes to a complete stop. Chilipeppr gets confused and then thinks the toolpath is at the origin. It spins up about 3,500 commands then if I wait long enough it eventually jumps to another region of the job and cuts a small circular area. It did the exact same thing twice in chilipeppr and a third time in coolterm.

    After aborting the job, weird things happened. When trying to jog the z axis up it started jogging down, jogging z down also jogged down. Upon disconnect and reset everyting worked fine again. I have no clue where to start with this – but it seems like bad things are happening on the hardware?

    Can you please post what build number you are on? That’s the $fb value in the $ display — Thanks

    Can you also describe your machine a litte – I see meshcam issuing a G1A command. Do you have an active A axis?
    Is this a new build, or have you run it with other jobs – successfully?

    What is the diameter of the tool you are using, and milling MDF?
    From video, seem a wide cut, or perhaps that is multi pass result?
    It might help if you post all your parameters to your GDrvive (Output of $$ command). From that we can see what TinyG thinks your machine looks like.

    [fb] firmware build 435.10
    Tool is 1/4″ End Mill (multi pass)
    $$ Below

    The machine is a printrbot beta: http://printrbot.com/shop/printrbot-cnc-beta-01/. I bought it assembled and configured and haven’t changed any settings. I have removed the raspberry pi from the workflow. I have had only 2 successful prints to date with a file generated by makercam. That same file from makercam now fails on the machine with a different but similar result to what is documented here. Ie, chilipeppr thinks the tool is at origin but really it is just hanging over the spoiler board, stopped mid run. I thought I was having CP problems until it had the same issue when sent via Coolterm.

    Can you post the makercam file somewhere where we could try it out?

    –thanks

    Here are two files I’ve run from makercam that are giving me issues:

    Finally back to my shop. I’ve just run part1.nc on build 440.14 – our current edge build. It’s working well – other than I don’t have quite enough table for it and it crashes into the edge on my Shapeoko2. 440.14 is what Chilipeppr is running these days so I’d recommend updating to that build.
