Tormach will be closed on Monday, May 29th in celebration of Memorial Day and will reopen at 8:00 am CST on Tuesday, May 30th.


To apply a tool length offset from a stored value in the tool table, program: G43 H~

  • H~ is the tool number associated with the length offset to be applied.

NOTE: Generally speaking, the value of the H~ word should match the active tool number (T~ word).

It’s okay to program using the same offset already in use, or to program without a tool length offset (if none is currently being used).


It’s an error if:

  • The H number is not an integer
  • The H number is negative
  • The H number is not a valid tool number
