Looks like there is a bit of a problem there:

I don't quite understand why the fillets go above the G0 and below the G1 moves.

As for 'M7' add this to your hal:

net m7-command <= halui.mist.is-on => parport.0.pin-<your_pin_number_here>-out

Hi,

For every gcode segment, we calculated the velmax "vm" for the segment given the curvature extrema of
that segment. The curvature extrema is retrieved by c++ functions that iterate over a spline, clothoid curvature.
For arc & line, the curvature is constant and easyer to retrieve.

If you look at the results, i think they aren't shocking or out of scope. My first impression is ok for the vm values.

Warning: Spoiler!

From here we can do the look ahead function.

Your 'spindle-on' signal is not connected to anything:

net spindle-on      => parport.0.pin-16-out

Try:

net spindle-on     <=  spindle.0.on  => parport.0.pin-16-out

Thanks for that info. I have been doing that for years now. It makes it impossible to upgrade or update a machine if you modified the source. I suppose I will just have to do it again.

Taig Lathe conversion to LinuxCNC: M3 is not turning on spindle

I am moving away from Mach3 (yay!) and created a StepConfig from the Mach3 XML file. I had to tweak some settings, but in the end the X and Z axis are moving properly. On the pin configuration I had to add the ESTOP OUT pin, which is working now. However, M3 is not turning on the spindle. With a scope and while using Mach3 I figured out that the spindle turns on when pin 16 goes HIGH. The spindle doesn't use PWM, it's just single speed. So, in the parallel port pin setup I tried Spindle ON, Spindle CW and Spindle CCW for pin 16, but nothing happens when I issue M3 on the MDI or when I run a simple GCode program. On the scope, I don't see the pin change logic level when I issue an M3 command. I also tried to set Mist Coolant on the pin but M7 doesn't do anything either.

The parallel port is set in OUT mode. As far as I understand, that makes pin 16 an output from the PC to the lathe. I have 3 parallel ports on the PC and I tried them all with the same result, thinking that maybe pin 16 was unresponsive on the first port.

I'm on LinuxCNC 2.9 and I am attaching my HAL file if that helps.

Any suggestions?

Thanks

This should give you A-axis jogging with 'Home'/'End' keys

You would likely need to add these to the 'on_key_event' function in 'bin/gmoccapy':

        elif keyname == "Home" or keyname == "KP_Home":
            button_name = "a+"
            if signal:
                self._on_btn_jog_pressed(None, button_name, fast)
            else:
                self._on_btn_jog_released(None, button_name)
        elif keyname == "End" or keyname == "KP_End":
            button_name = "a-"
            if signal:
                self._on_btn_jog_pressed(None, button_name, fast)
            else:
                self._on_btn_jog_released(None, button_name)

With the other control does the axis jog the same direction? X+ = X+ travel on both machines.
If the jog is correct is the Post the same?
