Sure. Sorry. I didn't think there was any interest.
This is to check if the coordinates and the fixtures are all setup correctly before starting the actual job. It moves to the bounding box (XY only) of the loaded program, goes around once and then returns to its old position.
It was a feature I liked in bCNC which I used with GRML before switching to LinuxCNC on my new machine.
This is my .axisrc
Code:
if hal_present:
boundcomp = hal.component("boundaries")
boundcomp.newpin("xmin",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.newpin("xmax",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.newpin("ymin",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.newpin("ymax",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.newpin("zmin",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.newpin("zmax",hal.HAL_FLOAT,hal.HAL_OUT)
boundcomp.ready()
if vars.metric.get():
conv = 1
else:
conv = 1/25.4
# this function is called at [DISPLAY]CYCLE_TIME interval
def user_live_update():
min_extents = from_internal_units(o.canon.min_extents, conv)
max_extents = from_internal_units(o.canon.max_extents, conv)
boundcomp['xmin'] = min_extents[0]
boundcomp['xmax'] = max_extents[0]
boundcomp['ymin'] = min_extents[1]
boundcomp['ymax'] = max_extents[1]
boundcomp['zmin'] = min_extents[2]
boundcomp['zmax'] = max_extents[2]
and this is goes in $SUBROUTINE_PATH/boundaries-scan.ngc
Code:
O<boundaries-scan> SUB
(-------------------------------------------------------------------------------------------------------)
#<_UseInches> = 0 ( set to 1 to use inches here, or 0 to use millimeters )
#<_TravelFeed> = 3000.0 ( feedrate used to travel to and along the boundaries )
(-------------------------------------------------------------------------------------------------------)
M70 ( save current modal state )
G[21 - #<_UseInches>] ( use inches or millimeters as required here, units will be restored on return )
G30.1 ( save current position in #5181-#5183... )
G90 ( use absolute positioning here )
G40 ( turn cutter radius compensation off here )
G94 ( use feedrate in units/min )
G61 ( follow exact path, don't round corners )
( Move to first corner of bounding box )
G53 G1 F#<_TravelFeed> X#<_hal[boundaries.xmin]> Y#<_hal[boundaries.ymin]>
( Drive around the block )
G53 G1 F#<_TravelFeed> X#<_hal[boundaries.xmin]> Y#<_hal[boundaries.ymax]>
G53 G1 F#<_TravelFeed> X#<_hal[boundaries.xmax]> Y#<_hal[boundaries.ymax]>
G53 G1 F#<_TravelFeed> X#<_hal[boundaries.xmax]> Y#<_hal[boundaries.ymin]>
G53 G1 F#<_TravelFeed> X#<_hal[boundaries.xmin]> Y#<_hal[boundaries.ymin]>
G53 G0 X[#5181] Y[#5182] ( return to where we were in X Y)
M72 ( restore modal state )
O<boundaries-scan> ENDSUB
M2
Then I created a new line under [HALUI]
Code:
MDI_COMMAND = O<boundaries-scan> call
which I have mapped to a button on my pendent.
