Something like this seems to work but I have not comprehensively tested for any side effects.

    /* check for reached end of move */
    if (! (&joints[jno])->free_tp.active) {
        /* reached end of move without hitting switch */
         (&joints[jno])->free_tp.enable = 0;
        rtapi_print_msg(RTAPI_MSG_ERR,_("j%d end of move in home state %d, homing aborted"),jno, H[jno].home_state);
        for (int j = 0; j < all_joints; j++) {
            if (!H[j].homed) {
                H[j].home_state = HOME_ABORT;
            }
        }
        return 1; // abort reqd
    }

I was able to test that code and it worked on my machine! Will run it and post if any issues arise.

Went to run a file generated from sheetcam and got "g92 offsets are not allowed" error. Documentation seems to want a g38 instead of a g92.

We probably should suppress that error when #<tube-cut>=1.

In the meantime you could hide it by creating a custom_filter.py file in your config directory with the following contents:

import types

def set_g92_detected(self):
    if not self.tubeCut:
        self.set_code_error()
        self.errorG92Offset.append(self.lineNum)
        self.errorLines.append(self.lineNumOrg)

self.set_g92_detected = types.MethodType(set_g92_detected, self)

Alrighty will look into the source code and give that script a shot in the meantime.

What's interesting is I was able to get it working yesterday in 2.9.2. Same gcode as before. So something happened to break it in 2.10.

Have a few quality of life questions regarding the a axis

How do you increase the jog speed? I've set it in the default angular velocity in just about every location I can think of (display ,traj, kin, etc). Stuck at 1 degree per second.... Might add another slider for A.
Is there a keyboard shortcut to jog a?

Does THC work when tube cut is 1? I tried it and it just dove into the pipe. Probably needs some tuning on my end.

Finally is their a way to make the display more relevant? Right now just displays a line in the xyz and the "cone" revolves around that line for the a axis. Kinda hard to see what line it is on.

Thanks for all the help!

There have been many changes since 2.9 so I am not surprised.

Good question, my sim seems to follow the rate in the jog slider but I am not sure in what units...

Is there a keyboard shortcut to jog a?

I thought that it did but not 100% sure. Tube cutting is experimental and was created for one particular user. We make changes dependant on their feedback. I think that THC would not really be required for tube cutting but I don't do any so I am not really sure.

Finally is their a way to make the display more relevant? Right now just displays a line in the xyz and the "cone" revolves around that line for the an axis. Kinda hard to see what line it is on.

I "think" that you may need to play around with the GEOMETRY settings.
