The GOHOME Command [MLEPC]
The GOHOME command is used to allow a part programmer to return the tool to a home position either by register or code output. Depending on QUEST settings, the GOHOME command might also output a STOP or OPSTOP command after reaching the home position. This command is valid for all machine types.
There are two forms of the GOHOME command:
![\textbf{GOHOME / }
{\small \sim}\!\begin{pmatrix},
\begin{pmatrix}\begin{array}{l} \textbf{XAXIS} \\ \textbf{YAXIS} \\ \textbf{ZAXIS} \\ \textbf{UAXIS} \\ \textbf{VAXIS} \\ \textbf{WAXIS} \\ \textbf{QUILL} \\ \textbf{AAXIS} \\ \textbf{BAXIS} \\ \textbf{CAXIS} \\ \textbf{AAXIS},\textbf{TABLE} \\ \textbf{BAXIS},\textbf{TABLE} \\ \textbf{CAXIS},\textbf{TABLE} \\ \textbf{RAM} \big[,n \,\big] \\ \\ \textbf{NEXT} \end{array}\end{pmatrix}
\begin{bmatrix} ,\! \begin{array}{l} \mathit{value} \\ \textbf{MINPOS} \\ \textbf{MAXPOS} \\ \textbf{UNKPOS} \end{array}\,\end{bmatrix}
\end{pmatrix}](../../_images/math/7ed325e363351a0e599f27428314bb900a2a1f4c.svg)
If the GOHOME command is programmed without parameters, it will return the tool to a home position defined by the HOMEPT command, a default starting position or alternately, to the last FROM position coded in the CL file. The home point depends on the type of machine.
If the GOHOME command is coded with parameters, only the named axes will be positioned to their default or specified home positions. See here for a table correlating axes name keywords with machine axes. See the HOMEPT command for details on defining axes home positions. The following examples both position the Z-axis to the default home position first, followed by a move to the X-axis and Y-axis default home positions:
GOHOME/ZAXIS GOHOME/XAXIS,YAXIS
or
GOHOME/ZAXIS,NEXT,XAXIS,YAXIS
Note
It is important to note that both TRANS amounts and ROTABL without ROTREF amounts are canceled for any rotary axis that is moved to the HOME position.
