G53 not ignoring tool length offset after a Python M6 remap

Category: Advanced Configuration

Not sure but I think that 'emccanon.USE_TOOL_LENGTH_OFFSET(pose)'
might actually not be a good approach here.

 Note that 'G53' will actually use the 'tool_offset' values to calculate the target coordinates:

if(block->z_flag) {
            *pz = block->z_number - s->origin_offset_z - s->axis_offset_z - s->tool_offset.tran.z;
        } else {
            *pz = s->current_z;
        }

My guess would be that your change of tool-length is possibly not reflected in 'tool_offset.tran.z'.

Generally I've become very cautious about using 'emccanon' commands to manipulate offset values  in remaps. I've had a similar issue setting work offsets this way.
I changed to using 'self.execute(..' instead (although that has its own pitfalls).

See the mentioned issue with work offsets:

I noticed that after starting it doesn't load the 'true' state
in radiobuttons .

I modified this logic a bit and now it works:
rabiobutton with "radiotrue/true/radiofalse/false'
checkbox with 'checktrue/checkfalse'

What do you think about this?

Hmm so I had checked the datasheet earlier, never actually looked at price and availability, I see what you mean.

The main idea was to save pins, they run out quickly on the tang nano. I guess the simplest solution is to step up to the spartan 6.
There is OctoQuad by DigitalChickenLabs for the pi pico that will do a similar thing for 8 encoders via I2C but as you say it would also require a new plugin.

Cheers.
Russell.
