Need helps with Heidenhain Control

[Tinhman]

Good morning Guys,

I would like to send my tool home in Z-axis and X Y to a fixed location (x-19.5 Y+11.5 and always calculate from center of my machine) before any rotation move.

Can any one give me a sample code for this in Heidenhain control.

Thank you in advance.

You will have to  use  the  machine  coordinate output as your secondary coordinate viewing  system  to find out what machine coords the XY point is ( so that it always stays the same no matter what your work origin is).  I am going to guess that your machine coordinate system is Z negative  when  moving away from the spindle so I'll go with a Z-5 for that . That is 5 mm  from the machine limit  or Z-0.2 inch. the other two coordinates , you'll have to find out , 

but the  line  goes L X xxxx Y yyyy Z -0.2 M91 FMAX  - , where the crucial thing here is the M91

I strongly recommend you do not include a Z  move at FMAX when you are testing.  When I worked for a MTB that integrated 530's Z0. was the pallet rest surface on 5 axis machines.  So Z-.2 M91/M92 FMAX would not be fun.

Use "M140 MB MAX" to send the tool home. It moves the tool home in the tool axis, to the limit.

You can also use M140 with a distance, but in this case "MAX" tells it to go as far as it can.

And as previously mentioned, M91 is the "machine reference" code.

M140 MB MAX      (Move Back ) is only  available on  the HH530 and  upwards ....
