Z Probing on Tronxy Melzi 2.0 whatever......

peta

Hey its me again, since several Days im trying to get my Z Probe working.

The actutal state is that my probe is reacting to H and L. Z Axis directions fit. X and Y endstops working correct.

But my Z Home via Repetier Host isnt working.

Maybe you guys could help me....

would be nice, i dont have a clear overview right now it is full with endstops in my head.

heres my configuration.h

The one who gets my machine to work will get a donation. Please help

shogun

I think your z feedrate is to low

peta

Sry, that didnt helped. Still no working Z home

shogun

#define MIN_HARDWARE_ENDSTOP_Z false -> true

#define ENDSTOP_Z_MAX_INVERTING true ----> false

peta

Ok, shogun please send me your paypal adress.

Another Question:

How can i make repetier host safe z homing in mid of the bed. My probe is sitting on the left of my nozzle so it tries to z home where it cant home.

I already wrote in config.h

#define ZHOME_X_POS 105

#define ZHOME_Y_POS 105

peta

Another Problem:

Managed to home z with this one :

G1 X105 Y105 F5000

G28 Z0

But the Problem is that my probe triggers, goes up and then normally down and crashes into the bed

peta

Fixed Height:

G29 Gives me this one

RECEIVED: fatal:G29 leveling failed! Printer stopped and heaters disabled due to this error. Fix error and restart with M999.

peta

Nevermind fuck autoleveling went back to normal. thx everyone who some tthoughts about it

RAyWB

If you write G28 Z0 you go to the point you want to figure out with Z-Probe.
write Z28 Z instead.

RAyWB

Sorry Typo.. i meant G28 Z

Zuikkis

G29 fail is probably because you start autolevel too low, Z probe is already active.

head crash after Z home is because you have set "#define Z_PROBE_BED_DISTANCE 10".. It will try to go to 10mm lower after homing Z, because it thinks that Z probe triggers at Z=10! I had the same problem. I have set that value to 0, then use "Z_PROBE_SWITCHING_DISTANCE" to set the actual offset between probe and bed. I'm not sure if this is correct way, but seems to work.

You can change those values from the EEPROM too, no need to recompile.

Then i also defined "#define ENDSTOP_Z_BACK_ON_HOME 10".. after Z home, it will lift Z by 10mm, which is high enough to deactivate the probe and G32 works.

I home and autolevel with these commands:

G28
g1 x40 y40
G32

The g1 is needed because G32 first goes Z_PROBE_X_OFFSET to the left, banging the x min endstop..

G28 homes Z at xmin/ymin, make sure you are above the bed there.
