Homing Z axis - wrong direction :(
-
hi guys
i would appreciate if you could please help me with a minor problem
on my corexy printer - while homing the bed it keeps going down instead of going up.
when i press the +5 Jog button it goes up and for -5 the bed goes down (is it ok?)
right now i am tring to setup my bl-touch sensor and when i try to use G30 command
the bed goes down instead of up. also when i try home Z and home all - the also bed goes down.
btw, at the reprap configuratore chose for z axis backward is it ok?; Drives M569 P0 S1 ; Drive 0 goes forwards M569 P1 S1 ; Drive 1 goes forwards M569 P2 S0 ; Drive 2 goes backwards M569 P3 S0 ; Drive 3 goes backwards!; homez.g ; called to home the Z axis G91 ; relative positioning G1 Z5 F6000 S2 ; lift Z relative to current position G90 ; absolute positioning G1 X-13.5 Y20 F6000 ; go to first probe point G30 ; home Z by probing the bed ; Uncomment the following lines to lift Z after probing ;G91 ; relative positioning ;G1 S2 Z5 F100 ; lift Z relative to current position ;G90 ; absolute positioning

@jaysson_ch The simple thing to try is to reverse the motor direction. Assuming P0 is X, P1 is Y and P2 is Z, change P2 from S0 to S1.
The cofigurator can only make a guess as to which way a motor turns and which direction means up or down.

I am also pretty sure you need to reverse z motor

@jaysson_ch Also its important to remember that +5 should make the bed move away from the nozzle, increasing the Z distance by 5mm. Similarly a -5 jog should make it move towards the nozzle. So if you have a setup where the Z axis moves the bed, not the gantry with the XY motion system on it +5 should make the bed move down by 5mm.
