GrblHAL Web Builder Build failed: 422 - SAM3X8E

[PolyEng]

Hi, new to the whole issue thing on github so if im in the wrong place feel free to scold me.

The problem:

using the grblhal web builder and building release 20240330 for the SAM3X8E (arduino due) for the RAMPS 1.6 i get Build failed: 422

All settings are the defaut ones i only added the tick on >Advanced features >RS274 NGC expression support, as far as i undestand RS274 NCG is needed for probing (as now when issuing G38.3 through IOsender machine says invalid gcode , g code generated from iosender built in probing tab)

this is the output error from grblhal web builder:

SAM3X8E_RAMPS_16.json

My bad, the driver did not handle exough aux inputs to accomodate the probe. Should be fixed now. FYI the RS274 NCG is not needed for probing - and the compilation failure was due to the Arduino framework (?) defining a lower case symbol that shomehow messed up my code. After undefining the offending symbol the RS274 NCG option compiles and should work.

This is the message I get when I try to run g38.3 on my board with RS274 NCG NOT enabled, The noprobe thing I suppose it's because probe isn't enabled, even if probe input is enabled by default in the web builder

Build anew - I committed a fix yesterday. Or have you already done so?

[PolyEng]

yes i built a new fw and the it builds ok, but on io sender probe pin is always triggered, toggling pin 12 as per https://github.com/grblHAL/SAM3X8E/blob/master/Arduino%20Due%20shield%20pin%20mappings/ramps_1.6_map.md does nothing, so i cant run a probe cycle since probe is always triggered.

So has probe pin been changend or is my pin12 input port fkd?

additional notes

1 measuring with a multimeter shows logic 0 on pin 12 , when (as far as i understand) it should have by default pullup activated (so i should read 3.3V)

2 i will try to swap the due with a new board and report back

UPDATE: Swapped the Due with a new one and nothing happend, so the probe pin 12 is unresponsive.

UPDATE 2: https://github.com/grblHAL/SAM3X8E/blob/master/grblHAL_Due/src/ramps_1.6_map.h seems like probe pin is digital PIN 21

define AUXINPUT3_PORT PIOB // Due Digital Pin 21

define AUXINPUT3_PIN 13

if PROBE_ENABLE

define PROBE_PORT AUXINPUT3_PORT

define PROBE_PIN AUXINPUT3_PIN

endif

@terjeio is there any way to support you for your wonderful work?

[terjeio]

I have now updated the board "drawing" to match the board map.

Currently I do not accept donations since EU(?) regulations requires me to declare donations beforehand, even which country they might come from - and since I am not able to look into the future how can I do that? If I do accept donations anyway I guess I may lose access to banking services, but not I am not sure since this is not stipulated in the form I have to fill out now and then...
