    Re: G-code editor

    I imagine you could also do this with different tool numbers for different cutters in the CAM, or by using tool wear offset in the controller?

    Re: Tormach sales

    Yes; this is one of the ways that import tariffs hurt US export businesses.
    Free trade was a mistake! Mercantilism at its finest! Forbid the export of gold bullion! Who's with me?

    Re: G-code editor

    I use gedit on the Linux box that runs PathPilot.

    Note that PathPilot supports the full LinuxCNC language, which lets you declare and use variables right in the code.

    See for example: G Code...

    Re: Electronic tool setter NC?

    Yes, you can update PP.
    Either update the Python code that controls the tool setting routine, or update the low-level LinuxCNC pin definitions to add an inverter to the pin.

    Re: Slant-Pro Re-Sale Value ?

    This is the land of the free market. The way to get in line is to say "I offer <$7500+X>"

    If I had the space, I'd make an offer, but sadly, no.

    Honestly, you might need to put in a new hard drive, and THEN re-install.
    Tormach doesn't make it very easy, because they ship the drive pre-installed.
    Perhaps you can buy the $20 USB "upgrade" to...

    Re: buying PCNC 1100, am I asking too much?

    I think you missed a zero there :-)

    Re: buying PCNC 1100, am I asking too much?

    If you are very worried about anything measured in one-ten-thousandth of an inch (or 10 microns or less) then you will be disappointed by any mill under 100k. And even some mllls over 100k.

    As long as they don't get too hot, you should be fine.

    Re: Tormach PCNC 770 - Mach 3 - Windows 10

    Yes, PathPilot IS Linux.
    The Mesa cards have some support under Windows, but I think the 5i25 only has 32-bit drivers.
    (It is, after all, a PCI card, so kind-of trailing edge at this point ...)

    Re: Tormach PCNC 770 - Mach 3 - Windows 10

    I don't have experience with that particular setup, but I have experience with various computing/control systems, and I think it's GREAT that the parallel port is finally dying.

  17. Re: what code for a tool change to eliminate the user confirmation pop up

    If you want a single line of code that changes the tool without involving the ATC or the pop-up dialog, you can also have your post processor emit this for tool changes:

  18. Re: what code for a tool change to eliminate the user confirmation pop up

    You need to set both T1 and H1 with the G43.
    Also, the idea is that "M6 is the macro to make the tool changer "go"" which means that you can edit the code for that macro to not pop up the dialog...

    Re: Oval shaped lollipop cutters?

    This is a prototype, so there will only be a few parts. (As prototypes go, there will surely be more than one, though :-)
    The groove is just under 3mm deep in the wall of the bore.

    Re: Oval shaped lollipop cutters?

    Thanks! The main problem with all of those that I found (also known as "canoe joint bits" it seems) is that they are too wide -- my bore is 25mm, most bits are 1-1/4" or 1-1/2" which won't fit :-(

    Oval shaped lollipop cutters?

    I have an interior sidewall groove that needs to be rounded -- it's like a thread, but cut with a scoop instead of a vee shape. Luckily, it's in 6061 aluminum, so not very hard to cut.

    The false halt happens when the probe is disconnected.
    There is zero chance that that problem happens because of the voltage difference.
    It's much more likely that the problem is either loose...
