M28 Disable Limit Abort
M28 is used to write your own home program instead of using G28
to home the machine. WinCNC normally aborts a program when a
limit switch is encountered. Adding M28 to a G0 or G1 command
disables the program abort and instead stops the limited axis while
allowing other axes to continue. Limit Cushions are disabled while
using M28 so any move done with M28 should be done slowly
to avoid machine damage. M28 must be specied on each line
separately.
M29 Disable Limit Abort
M29 is used to write your own home program instead of using
G28 to home the machine. Adding M29 to a G0 or G1 command
disables the program abort and instead stops the current G-Code
line but continues on the following line. M29 must be specied on
each line separately.
M37 Measure Tool - M37 O# Z# W# H# T#
M37 is used to set Tool Length Offsets. The end of the tool is rst
set to a known position. M37 is then specied to set the tool length
offset.
O# manually species the tool height offset.
H# is the tool number of the currently loaded tool. Use this with
mode 0 only, M0 on the ATC line in the WinCNC.ini le.
T# is the tool number of the currently loaded tool. Use this with
mode 1 only, M1 on the ATC line in the WinCNC.ini le.
Example: Jog the Z head to the spoil board. Enter M37Z0 to the
Z work coordinate to 0. Once tool length offsets are set, Boundar-
ies may be used to insure that the table is not routed by accident.
Normally zero values are set to the top of the spoil board. Use
G92 to set material thickness if programs reference zero from the
top of material. This eliminates re-measuring tool for different
thickness materials. G43 and G49 are used to enable and disable
offsets.
M37.1 Measure Tool for Calibrating G37 - M37.1 Z# W#
M37.1 is used to store a tool measure in the TM1 variable. This
command is used primarily with calibrating G37 for automatic tool
measuring.
