Kossel Mini and latest Marlin

Has anyone tried the new Marlin update from Johann?

It has lots of settings messed up and I had to debug them to work with my Kossel Mini.

But I can't make the auto level probe work. I'm using the old mechanical probe type. When I try to run G29, the action appears as if the probe microswitch is permanently triggered. Anyone know what's wrong?

I know it's not an electrical problem because if I switch back to the old Marlin, it works just fine.

No expert, but sounds like the settings for the probe switch are reversed so it thinks the signal should be high when it is actually low or vice-versa.

I think so too. But where to set it?

Config.h file, I think the probe settings should be towards the end, though I use Repetier, not Marlin.

It is also possible that the probe is configured to use the z-min endstop pin. If this is the case, I believe you need to flip the end stop itself. But the probe settings should tell you how it is configured.

M119 is your friend. Once you confirm that the endstop is inverted, there's a setting in every firmware to invert the signal.....

I've tried inverting it. Checked via M119 and shows correct logic inverted or not. Z probe works but M29 still probes in mid-air.

Reverting to former firmware.

When you check with M119 you have also X min e Y min? If yes put in pins.h:

#ifdef DELTA
#define X_MIN_PIN          -1
#define Y_MIN_PIN          -1
#endif

I solved in this way...

Well yes. It X min and Y min shows up when I do M119.

But where do I put your code? Because on pins.h I see near the bottom these lines:

#ifdef DISABLE_MIN_ENDSTOPS
#define X_MIN_PIN -1
#define Y_MIN_PIN -1
#define Z_MIN_PIN -1
#endif

Should I put them after these?

Update: I just commented the Z min pin and uncommented the #define DISABLE_MIN_ENDSTOPS in Configuration.h and it worked! Thanks for your help MagoKimbra.

#ifdef DISABLE_MIN_ENDSTOPS
#define X_MIN_PIN -1
#define Y_MIN_PIN -1
// #define Z_MIN_PIN -1 <----
#endif


Thanks for your help MagoKimbra.

you're welcome...

Your solution it's same... In my firmware i use #ifdef DELTA because it's only firmware for cartesian, delta, corexy printer3d...
Ok....
