Prise d'origine Machine

Hello everyone,

I have the version 2.9 pre , and each time I turn on the machine I have to do my original plugs , while 
POSITION_FILE = position.txt & NO_FORCE_HOMING = 1 are valid in my .ini file.

Does anyone have the same PB & especially the solution 

Thanks

Try also setting HOME_SEARCH_VELOCITY = 0 for each joint too.

Hello ,

I come back holidays , and i tried HOME_SEARCH_VELOCITY = 0 on each axes but don't fonction .
for your information , i work with the 2.9 Version  xyzac-trt "TCP"

Thank you

Are you trying to avoid having to press the "home" button?

I have my lathe set up with absolute encoders and have just got used to pressing the button (nothing moves, it just flags everything as homed)

You could try connecting the halui.home-all pin to joint.0.amp-enable-out

Hello ,
No, I just want to avoid redoing my origins every time I reallume my machine. 
My positions are well recorded in the file position.txt 

POSITION_FILE= position.txt
NO_FORCE_HOMING = 1
&
HOME_SEARCH_VEL = 0 on all my axes .

Despite this, Linuxcnc does not start on the positions from where I stopped the machine. I can't have the control without redoing my origins.

Thanks



 

I have tested on an Axis simulator, and it seems to work as I expect.

If you have position.txt defined then the machine position at power-on will be displayed the same as it was at power-off.

If you have [TRAJ]NO_FORCE_HOMING = 1 in the INI then you can start running G-code immediately without homing.

If you want to be able to home (though I am not sure why you would?) then you can experiment with adding HOME_ABSOLUTE_ENCODER = 2 to each [JOINT_N] section.

Is it possible that your NO_FORCE_HOMING = 1 is not in the correct section of the INI?

In all LinuxCNC branches to date, NO_FORCE_HOMING
applies to identity kinematics only.

The xyzac-trt kinematics uses switchkins
Ref: github.com/LinuxCNC/linuxcnc/blob/master...xyzac-trt-kins.c#L17

which uses KINEMATICS_BOTH (not KINEMATICS_IDENTITY)

Hello ,
This is my .ini File .

Thank you
