Homing past Z0

BeastPrinter

The firmware was working perfectly last night with regards to G30 and G32.

Today it has stopped working correctly...

When I turn on the printer the Z moves up 10mm... but the firmware sets Z0 to the position of the nozzle when the printer is turned on.

So after the printer turns on and the nozzle raises 10mm... I can move the Z from Z10 back to Z0... but I can't go below Z0 when homing with G28 G32.

How can I make the printer home past Z0 when homing with the Z probe?

After doing a G28, measure the distance between the bed surface and the tip of the nozzle

then set' Z_PROBE_HEIGHT' to that distance (you can edit the value in eeprom from repetier config menu)

then do G32.

You may have to fine tune the height value to get correct Z0 distance from bed o nozzle.

I had a error in start z probe going at the end to start position, so that might be the problem you had. SHould work now but remember to home x,y prior to z probing.
