[Grbl_Esp32 Issue#627] Homing Issues

#1 – bDuthieDev 于 2020-10-06

Ran into this same issue myself. Here was my fix:
$Homing/Cycle5=
$Homing/Cycle4=
$Homing/Cycle3=
$Homing/Cycle2=Y
$Homing/Cycle1=X
$Homing/Cycle0=Z

#2 – Mboss32 于 2020-10-06

Thanks @bDuthieDev! What file did you add the to?

#3 – bDuthieDev 于 2020-10-06

Just enter from a console. Use $S to see all your current settings.

#4 – bdring 于 2020-10-06

We are slowly moving as much as we can to run time settings to reduce the need to compile. We support all the traditional $$ menu numeric settings and a newer text base settings style. You can see all the new settings by sending $S.

It is a lot of settings, but if you can filter it. Send $cycle to see any setting with the word cycle in it. Just be careful to avoid existing commands like $X.

Also, to find descriptions of error codes, send $E to see all of them or $E=18 to see a specific number.

You can home multiple axes at once. A traditional homing might be.

$Homing/Cycle0=Z
$Homing/Cycle1=XY

More on settings is here…

Thanks! Is there a way to add these to defaults.h the settings so they reload after RST commands?

#7 – bdring 于 2020-10-06

Yes,

They are bit masks. The most readable way to do it is like this.

#define DEFAULTHOMINGCYCLE0 bit(ZAXIS)
#define DEFAULTHOMINGCYCLE0 (bit(XAXIS) | bit(Y_AXIS))

#8 – Mboss32 于 2020-10-06

Thanks for the suggestion Bart!

Unfortunately, I have tried the above in my machine file, and in defaults.h and it does not work. The defaults do not load after compiling/upload or RST commands.

I also tried this method from the 6packstepstickXYZv1.h example (pleased in machine file).

#ifdef HOMINGCYCLE0
#undef HOMINGCYCLE0
#endif
#define HOMINGCYCLE0 bit(Z_AXIS) // Z first

#ifdef HOMINGCYCLE1
#undef HOMINGCYCLE1
#endif
#define HOMINGCYCLE1 (bit(XAXIS)|bit(YAXIS))

None of these methods appear to work, the settings are still blank after each test.

#9 – bdring 于 2020-10-06

Could you paste your complete machine definition file here. I will give a test on a controller.

#10 – Mboss32 于 2020-10-06

Sure thing – it is the SPI_daisychain with just a few mods. Thanks!

Not at my computer right now, but change this

“
#ifdef HOMINGCYCLE0
#undef HOMINGCYCLE0
#endif
#define HOMINGCYCLE0 bit(Z_AXIS) // Z first

#ifdef HOMINGCYCLE1
#undef HOMINGCYCLE1
#endif
#define HOMINGCYCLE1 (bit(XAXIS)|bit(YAXIS))
`

to this

`
#define DEFAULTHOMINGCYCLE0 bit(ZAXIS)
#define DEFAULTHOMINGCYCLE1 (bit(XAXIS) | bit(Y_AXIS))
“

#12 – Mboss32 于 2020-10-06

No joy using the suggested edits

#define DEFAULTHOMINGCYCLE0 bit(ZAXIS)
#define DEFAULTHOMINGCYCLE1 (bit(XAXIS) | bit(Y_AXIS))

Its like the $Homing/Cycle setting variables aren’t being assigned from the #defines, I have been looking for this in the code but haven’t found the right section yet.

#13 – bdring 于 2020-10-06

I am sorry, that feature is brand new this week and still in the devt branch. I am hoping to merge that with the main branch soon, but you could use it now to fix your problem.

#14 – bdring 于 2020-10-07

Merged with main….closing

#15 – Mboss32 于 2020-10-07

Thanks all for the help! I will test the new main out in the morning
