How to let steppers move when reaching axis zero
-
Hi,
I want to ignore the 0.00 position on a given axis and keep going in the negative direction
As of now, if I press controls to move the axis when they are at 0, they do not move
I have added this command in my config.g file
M564 H0
As I thought it would solve this issue. Any idea? Thanks! -
@jcsb1994 Once the printer has been homed, the firmware will respect the axis limits and not allow moves beyond them. The reason is that normally those axis limits are also physical limits so respecting them will prevent mechanical collisions.
To move more negative than zero, you therefore need to define the axis minimum as a negative value using M208 S1 https://duet3d.dozuki.com/Wiki/Gcode#Section_M208_Set_axis_max_travel

(M564)
The H parameter controls movement when homed/not homed.
The S parameter controls movement within/without min/max limits.

@fcwilt That would work too
