The retract options for 'Retract on WCS change' and
'Retract on work plane change' (3+1 machining) were turning off the
spindle and coolant and then turning them on again after the move.
this was unintended and is now removed. This will speed up the code
An update to Fusion 360 revealed that there was a
mistake in the post-processor code. The new version of Fusion raised
a warning when posting code, indicating there was a problem, but the post-processor worked
correctly anyway. The post-processor is now modified to prevent the
warning being raised. The generated code should be unchanged.
10th May 2021
The way in which custom post-processor properties
are defined has been updated to match the latest posts from Autodesk.
When viewed in the 'NC program' setup, the properties are now arranged in
groups with group titles. Makes it a little easier to navigate.
If you have a 'Manual NC - comment' immediately
before a 'Manual NC - Stop' operation, the comment will be output on the
same line as the M0 (or M1 for optional stop). This will cause the
comment to be displayed as a banner across the bottom of the screen.
If the comment happens to be the name of an image file, or video, then the
contents will be displayed where the toolpath preview normally is.
Added support for left hand tapping - sadly this
doesn't work in the current release of PathPilot. It's beign worked
Added a 'Retract on optional stop' to match the
'Retract on Manual NC stop' option that's been there for a while.
For people with ATCs, there a new pair of
properties to allow you to ask for an extra tool change at the end of a
program. Re-loading the first tool in a program can save a little
time if you're running the same program for multiple parts one after the

Added support for Manual NC commands to turn
inspection probing on and off. When inspection probing is on, WCS
probing routines do not in fact update the WCS. Instead they write the
results of the probing operations to a text file named 'inspection.txt' in
the user's file area.
This feature is turned on and off by adding a 'Manual
NC' operation with an operation type of Action. Set the action
text to Inspection on to enter inspection mode, set the action text
to Inspection off to switch back to regular probing mode.
For examples of how to do inspection reports, watch
Added support for partial circle probing operations
(boss and bore). (Path Pilot 2.7 and later)
Added support for position and size tolerance checking in all WCS probing
functions. (Path Pilot 2.7 and later)
Added Manual NC and tool library support for tool setting/checking.
Replaced 'Use G30' and 'Use G28' post-processor properties with much more
flexible properties to control retraction.
Full details of the updates are discussed in this
The XooomSpeed post processor provides a number of
functions not supported by the standard post processor from Autodesk.
500 WCS support
Some bug fixes for Smartcool support in drilling
Integrated WCS probing operations
In process use of electronic tool setter to set
tool lengths and/or check tool lengths for tool breakage
Expanded g-code tapping cycles (Required to use a
tension/compression tapping head on a PCNC440 with non-standard spindle
Support for I/O modules in generated g-code. (added
Some of the above require new custom properties to be
added to the Fusion 360 Post process dialog. These are described
Supports all the Fusion 360 WCS probing routines
(except axis rotation). You can use this with either wired or wireless
probes to perform a number of flexible probing routines to simplify your
setup procedures. Watch the following video for a tutorial on how
Fast probing speed (inch/min)
The feed rate used for the first part
of the probing operation. This is always specified in inch/minute,
nomatter what units are used for the g-code output. Suitable
values depend on the acceleration/deceleration performance of your
machine, but the default is 20 inch/min
Slow probing speed (inch/min)
The feed rate used for the final
probe. This will generally be somewhat slower than the fast probe
speed to ensure good accuracy of the final result. Defaults to 1
Slow probe distance (inch)
After the first, fast probe, the
probe will retract this distance away from the detected surface before
starting the slow probe. Default vale is 0.040"
In process tool setter support
The in process ETS support allows tools to be measured
using and electronic tool setter during a program run. Tools can
either have their lengths checked against the current settings in the
controller's tool table, or the tool table can be updated with the newly
These operations can be performed at the start of a
propgram, when each tool is loaded or unloaded or even after every machining
The ETS functions use Tormach's G37 and G37.1
extensions to the standard LinuxCNC g-codes. Before you use these
options, please make sure you have read the G37 and G37.1 documentation from
Tormach and make sure you have the G37 locations correctly set up and the
ETS diameter limit (inch)
The maximum diameter tool that can be
measured using the ETS. Generally this is the diameter of the pad
on the top of the ETS. No action will be taken for tools larger
than this except in the case of 'drills' and 'spot drills' which can
always be checked irrespective of their diameter. Likewise, probes
are never measured by the ETS routines.
Tolerance for ETS checks (inch)
For 'check' operations, this is the
allowed error between the measured tool length and the tool length in
the PathPilot tool table. It is the value of the 'P' word supplied
ETS op before start
What action to take before the start
of the first machining operation. The action will be applied to
all the tools used in the program, so long as they are not a probe and
they have a tool diameter (in the Fusion library) that is acceptable
according to the ETS diameter limit above. Options are 'none, 'check' or 'set'
ETS op before a tool is used
At each tool change, this operation
is performed immediately after a tool is loaded and before the operation
ETS op after a tool is used
At each tool change -- except the
first - this operation is performed on the tool being unloaded.
This will generally be 'check' in order to detect a tool that's been
damaged and abort the program so as to avoid damaging subsequent tools.
ETS op after every machining
Check/set tool length after every
machining operation. Useful with multiple WCS or CAM pattern
setups. Using the 'Check' option here means that the tool length
is checked after each machining operation. It it's out of spec
(Tolerance for ETS checks) then execution stops. In the case of
multiple parts in multiple WCSs the tool length will be checked after
each operation on each part and execution will stop the first time the
tool is detected to be out of tolerance.
I/O module support
The I/O support options make it possible to signal to
one of our USB I/O modules that various useful
actions are taking place in your program. the pre-configure applets
supplied with each I/O module can make use of these features to trigger
various custom sequences. User written applets also have full access
to this information
I/O ETS in use
Signals to the I/O module that one of
the ETS functions above is about to take place. This gives the
opportunity for the I/O module to open a cover over the ETS and/or
operate an air blast to clean the ETS.
I/O ETS ready
Select an input that PathPilot will
wait for before starting the ETS function. The idea here is that
the I/O module can request a delay to finish opening a cover and
cleaning with an air blast before allowing Pathpilot to continue with
the ETS function.
I/O flood cooling
Turn this output on any time that
flood cooling (M8) is running. typically this would enable
monitoring of a flow switch to verify correct operation of the coolant.
I/O mist cooling
Similar to I/O flood cooling
above, but this output is active with mist cooling (M7).
I/O Program running
The selected output will turn on at
the start if your program and turns off again at the end.
I/O Spindle running
Indicates that the spindle is turned
on (forward or reverse)
I/O tool change in progress
Turn this output on when a tool
change starts and back off again once the tool change is complete.
Tapping for PCNC440
Tapping operations are normally inpossible for a
PCNC440 because spindle reversing is not provided on that machine.
Normally set to 'M4', use the other
options to get spindle reversing working on a 440. If your 440 has
a USB I/O module with one of the outputs connected to the F/R and COM
pins on the BLDC drive, then you can have spindle reversing by
outputting one of the other options depending on which USB I/O channel
Use M3 M64 P0 if you have used channel 0 of
the USB I/O module to control the spindle direction and son on for the
other I/O channels.
This will work on all the mills, but
is essential on the 440 with non-standard spindle reversing. Instead of outputting tapping ops as a
canned cycle, this outputs long hand g-code to do the job. When
tapping is done in this way, the spindle direction is controlled using
the Spindle reversing options above.
