Offset after Homing in Y-Axis

Hi Guys,

how can i assume that when i home my machine in Y-Axis that G53 or G54 is set to 596mm and not to zero?

Greetings

Sounds like you might have a tool length offset applied or you have a value of 596mm set for your HOME_OFFSET for the Y-Axis.

The HOME_OFFSET is defined in your INI file.

Thx for your answer but u missunderstand me,

when i start the machine (Bending machine) i home all axes but i want that the Y-Axis has the value 596mm After homing and not zero how can i achive that?

If i do that with HOME_OFFSET the Y-Axis will move to the value 596mm but that would not be good that causes a chrash.
The Y-Axis should reference and then set the actual position to 596mm.

hope u can follow me, sry for my bad english.

Are you sure that you just do not want to home the Y axis then "touch off" the Y axis as 596?

HOME_OFFSET = the value of the position of your home switch.
HOME = the position the machine goes to when homing is complete.

I have a router that homes to the Y+ limit switch, which I have set as 62" with HOME_OFFSET = 62.0 , then it parks its self at 61.5" with HOME = 61.5 when the homing cycle is complete.

So when it homes the Y, it moves to touch the + limit, then it moves -0.5 inches and stops showing 61.5 on the the DRO.

I dont want the axis to move to the home Position! It should do the homing process as usual and then stop like no home Position is written in the .ini file, then it should set the actual Position to 596mm. Just like i do it normally with touchoff but without moving the axis.

I think i make a Little sketch and upload it here or take a Picture of the machine so you can follow me more easily.

Thx for the help so far.

Todd is telling you exactly what to do.

Set HOME_OFFSET = 596mm
This means that when the machine hits the home switch it will set that position to 596mm.

Set HOME = 596mm
This means that after the machine homes it will move to the "HOME" position which is the same position as the home switch as defined by HOME_OFFSET. Since home and home offset are the same then the machine will not move after it homes.
