Radds + DUE + Repetier Firmware Auto Bed Leveling

atilla

My problem is with "G28" command. When i do "G28" z axis home first touching is ok but second time z axis would like to go up. When i use "G32" i don't have a any problem. (I use auto bed leveling)

Example video's

I use repetier 92.9

My setting z probe;

First use dev version when z min = z probe. I don't know which bugs were fixed or not regarding that combination.

Then select homing order xy preheat z so you can define where to test z position. Use temperature 0 so it does not really heat. xy homing before z is essential.

If it still doe snot work describe exactly what is happening and what you expect and what your homing settings are. The video is a bit hard to follow.

MartinH

#define Z_PROBE_SWITCHING_DISTANCE 1 <<<<<<<set this to 3, gives probe a bit more chance to untrigger

#define Z_PROBE_HEIGHT -9 <<<<<<shouldn't this be a + value ,ie distance from bed-nozzle when probe triggers

Repetier

@MartinH good seen. -9 means to hammer bed into nozzle after homing, which is exactly the problem.

@MartinH @Repetier Now i change Z_Probe_Height 9. But problem is continues. I saw something wrong when G28. Please look at the video 0:50 second. When make z "0" after would like to make "z-41.99". I can't understand this is why? Can you help me?

Repetier

Have yo change dit in eeprom? Server has eeprom editor to change value directly there - changing in configuration.h will not change it until you explicitly load it back.

MartinH

What version firmware are you using ? dev version is a lot better.

Cant see where it is getting the Z-41.99 from, (wierd)

Maybe try running the eeprom clear sketch from arduino 1st and re uploading your firmware.

atilla

@MartinH @Repetier So sory but how can i clean the eeprom ? Because normaly DUE don't have a eeprom but RADDS have. Firmware i choose eeprom 1. Normaly marlin firmware use i can set eeprom in repetier host but repetier firmware eeprom setting not active repetier host. (Firmware dev version.)

Repetier

Just send

M502

M500

to copy from configuration.h to eeprom. Disabling is not a good option with autoleveling.

atilla

@Repetier @MartinH I do it but nothing change for G28.

Repetier

WHile you are using right homing order and z probe height i s 9 mm in eeprom you have

#define ZHOME_X_POS 999999

#define ZHOME_Y_POS 999999

so you do not say where to probe! Please set it to some working values like 50 and 50.

@Repetier @MartinH When i do G28 x and y home ok but when it start z home have an error.

Repetier

Have you set homing order xytz and set z probe coordinate where activating probe is possible e.g. 100,100?

atilla

@Repetier So sorry but where did am i do this setting in "Configuration.h" ?
