COREXY - Auto level & Z-homing

BrunoRebelo · April 2016

Hello,

I have built a SPARKCUBE XL with ramps1.4. i set the extruder 1 to the third motor..

im using the http://www.repetier.com/firmware/v092/ for configure the firmware...

So, i have set the option Mirror motor signals to other stepper driver (FEATURE_TWO_ZSTEPPER)) and then in "MIRROR STEPPER SOCKET" and choose the "Extruder 1"..

In the Endstops i have the follwing settings :

The X and the Y line to the Home properly ... this is not the case with Z....

I have an inductive sensor, connected to the Z-min-Endstop.

Problems:

a) When I run the G28 Z0, the Z axis moves extremely fast, but when I give the instructions for the Z move 10mm it moves at normal speed.

b) How can I set the Z0 for this to be at the top, when you activate the sensor.

am i configuring something wrong ?

Best Regards

Bruno

hello,

After some adjustments...

Problem A:

i have set Homming_feedrate_z to 5 instead 40 and the first problem was solved;

Problem B:

After execute the command G28 for homing all axis and then the G29... i got the folling result on LOG :
