M486: Object cancellation

[billhu1996]

May M486 be enabled in LPC and STM? M486: Object cancellation

define TRACK_OBJECT_NAMES 1

[jaysuk]

why do you think it doesn't work? Sending M486 by itself (on an STM build anyway) gives an answer back, showing that M486 is available. Have you got all the relevant labels in your gcode file?

Thanks,

Jay

Thank you for your reply.

Yes, I tried it and it didn't work. I'm using SGen_L 1.0 with esp8266 and v3.2.2. There are MESH related comments in my gcode

 94647: ;MESH:CalibrationCube
 95004: ;MESH:CalibrationCube(1)

1135 matches across 1 files

And I saw the source code in Pins_Duet3Mini.h

#define TRACK_OBJECT_NAMES 1

And that there is no such definition in Pins_LPC.h.

Finally defined in Pins.h

#ifndef TRACK_OBJECT_NAMES
# define TRACK_OBJECT_NAMES 0
#endif

So I suspect that adding this switch might work.

Thanks,

Bill

I'm using Cura 4.8.

It works for me if manually indicating an object using M486 Sx Will look into it further

Thanks,

Tracking object names is I think currently off in all versions of the firmware. The problem (on the LPC) is that of memory usage, with future versions already adding things like variables etc. there is already a lot of pressure on the available RAM. I'll add investigating what the impact would be of enabling this to my todo list.

I've enabled this feature in the V3.3-beta1_6 STM32 build. I will evaluate enabling the feature in the LPC build once I have a better understanding of the changes for v3.3-beta3 have on RAM usage.
