Advanced V carve random pocket/line

Recently setup my new pro xl. I’m new to cnc but have some preivous experience working with cad/cam etc…

I setup an advance vcarve to do a detailed letter “T” on a piece of wood. Everything seems to go ok but when I perform a tool change the router is doing a plunge cut in a straight line at the beginning of each toolpath near the top of the work piece. This line doesnt show up in the image and I can’t seem to figure out why its doing it.

Here is the code, im thinking maybe it is related to this “M03S18000” command which appears to be a prepositioning command? This also appears after the tool change from end mill to v-bit.

Any help would be appreciated.

Which post-processor do you have selected under Edit | Select Post Processor in Carbide Create?

Otherwise, please post the .c2d file, the complete generated G-Code, step-by-step notes on how you are securing your stock and setting zero relative to it and managing all tool changes, and a photo showing an attempt at cutting still in place on the machine either here, or if it’s something you don’t wish to show publicly to support@carbide3d.com and we’ll do our best to assist.

I tried remaking the file and the previous issue seems to have been resolved. However now after a tool change the vcarve tool paths are in the wrong place relative to the pocketing operations. workpiece is a piece of 3/4" plywood and its fixed securely at each corner in the t-tracks, it is laying flat. I set my x/y zero to the bottom right corner of piece and set z zero at top of ply in the center. Also I’ve noticed that after the tool change the machine tends to crash/slam in to the end of the +Y axis.

this sort of feels like the machine dimensions are not set up correctly in the carbide motion settings screen… I’d suggest taking a screenshot of that screen and posting it here, so that someone else with a pro XL can compare the values.

I used the loaded defaults for pro XL,

How are you managing the tool change?

Just following the motion prompts, when it says change the tool i change it. Then it goes to the bit setter and back to the work piece. Im clearing with 1/8 endmill and then vcarve with 90deg bit. But the issue seems to be the y-axis is off after the change.

this is sounding like where the skips happen…

yes, but why would it happen?

Only 2 things I can think of

  1. the homing is somehow further forward than expected
    or
  2. CM thinks the machine is larger in the Y than it is (as measured from the place it homes).
    I don’t have a Pro (just regular) so cannot check the Y dimension that is set… but hopefully @WillAdams or someone else has the correct value to compare with.
    (You can also, just in case, re-select this in the settings and see if it changes somehow)
