Home one axis without reference switch was created by goaran
Hello,
i have a 4 axis setup with a XYZ axis for the motion of the toolhead and a A-axis that is used to drive a reprap-kind of 3D printer extruder. This axis has no reference switch. What is annoying is that when i home all axis i have to seperately home that one in the menu (which just does nothing exept setting the homed parameter in hal to TRUE.
I tried to set the paramter in Hal to 1 per default but its not writable (which makes sense)
How can i achieve that this axis is homed at startup or together with the others? Or if that is not possible what is the HAL command to home an axis so i can put it to a pyvcp button without the need to search it in the menu every time..
thanks in advance

Hi
I don't know how you home the other axes, individually or all at the same time.
Assuming you home them together
HOME_OFFSET = 0.0
HOME_SEARCH_VEL = 0
HOME_LATCH_VEL = 0
HOME_SEQUENCE = 0
will home your A axis at the same time, but not move it at all, just set it as homed.
Adjust the HOME_SEQUENCE number if you want to home it after the other axes are homed etc etc
