    Re: Make a $25 Full 3D Probe

    If the input is 24V tolerant, then the same circuit as below, but perhaps with 2.2 kOhm resistor, should work fine!
    Fine-ish, actually -- the diode will have some voltage drop, and the resistor will...

    Re: Make a $25 Full 3D Probe

    The main question is what voltage the input on your probe port wants to see, and whether it's current operated like the Tormach one.

    If it can tolerate 24V, then you can bump up the LED resistor...

    I built something very similar out of a Teensy microcontroller a few years back. My Blue does air blast (through an external solenoid) but other than that, very similar mapping!

    Re: 4th Axis Contouring or only Indexing

    "Adaptive" is about how the tool moves sideways into the cut, much more than how it steps in Z.
    "Adaptive" is a form of "trochoidal" tool path generators, and the general idea is to:

    Re: 1100m Spindle Rebuild

    I would worry about 3D printed plastic melting, and before melting, shrinking because of the heat.

    Re: O.T., but only a little :-)

    That sounds annoying! I've never seen that, within a sketch.
    Outside a sketch (in actual modeling,) then the dimensions are only visible for as long as a sketch is visible.
    If you use the sketch to...

    On the lower end, there's still the Grizzlys.

    That looks like broken hardware, or perhaps an incompatible OS/graphics card driver.

    Re: 5 axis Tormach, would you get one?

    I think the reason is physics. You cannot make a rigid 5 axis trunnion machine with any kind of actual working envelope for $30,000.

    Re: 5 axis Tormach, would you get one?

    Yes, you need a paid subscription for Fusion to do the 5D stuff.

    Re: External Reset Button

    I don't think there is an external hardware pin pre-defined for this.
    You might need to hack the HAL and the bindings for commands to make the controller recognize your external button.

    Re: 770MX Spindle Keeps Stalling

    I don't think there is a maximum "recommended" size, but the max you can get into R-8 with typical collets is 3/4" and the max you can get into ER-20 with typical collets is 1/2".
