Which I have done useing the hal show config pulldown, but I'd also say 
that is about as clumsy a way as can be because you have to keep 
reselecting that parameter in order to see the new value.

I could see something carved up in gladevcp or pyvcp to couple some .hal 
scripts to effect that, which it might be possible to access in the 
gcode by a halui function calling a couple of remapped m100+ functions.

Mind you I have not done it because the foray's I have played with are 
those functions in the "align.zip" software kit. It could indeed run the 
machine to point the camera at the place the tool was, but without any 
command to revert it being visible, it turns around and runs it back to 
the starting position with no pause.  And when I asked about it, no 
response.  I assume because no one else can see the potential utility in 
being able to just clamp down the work in any old orientation, and use 
it to adjust the coordinate map to effectively square it up as if being 
held in a fixed jig. Very handy for carving a double-sided pcb in 
perfect registration for instance. So those camon/camoff buttons along 
with the align buttons are still there in my gui, but useless.

Perhaps what Danny wants to do is similar enough that a solution might be 
found for both of us? I don't know. I burned up at least 2 weeks, making 
a removable camera mount that could be used to find a feature on the 
workpiece that would consistently be removed and remounted, still 
centered on that feature.  So the camera problem is solved, but the 
software is not.

I assume that they must be, otherwise there is no point in the HAL
pins existing.
(And they are input pins, so exist for setting the values).

[Emc-users] Can speed/accel be changed without rebooting?

[Danny Miller]

I was going through the HAL and noticed the per-axis ini parameters are 
there.

Can they be changed without rebooting?  The machine will be at a stop 
for this.

Reason being, I use the standard cutting profile but I also have a 3D 
carving profile which increases the acceleration much higher.  To stay 
within the motor's performance curve, the max speed of the axes is 
limited for 3D carving.  And the carving profile's acceleration shakes 
the table in a way you just don't need for regular cuts.

So I was thinking, can I just make a PYVCP button that changes to the 
alternate profile, faster accel but slower linear, and back?

I've done 3D carving and then a toolchange to switch to an endmill for 
cutout.  No real biggie, but I couldn't switch to the 2D cut profile 
without rebooting, so I didn't reboot.  It'd be an interesting feature 
if it was just a button.
