Math Update

Hi everybody,
this is the next release of OpenCNCPilot. It's been quite a while since the last proper release, so the changelist is pretty extensive.
Also I didn't get to test this version as extensively as I would have wanted, so expect some minor bugs / annoyances.

Changelog (includes changes that were made since 1.4.2):

• added mathematical expressions in manual console / macros
• added a job runtime estimator (not very accurate)
• added grbl settings window
• added tool length sensor interface
• added probe command output
• added version check for grbl
• added M6 to list of commands to pause on
• made expanding panels persist after close and restart
• made settings persistent after OpenCNCPilot update
• made most output textboxes selectable/copyable
• improved translator for error/alarm messages
• improved gcode parser, now gives more warnings for incompatible gcode
• all whitespace is removed from gcode before sending to grbl
• fixed buffer syncing

misc bugfixes

fixed issues

• create height map window XMin TextBox didn't work correctly
• process stayed open after closing the window

also added a reset viewport button

some new features

I don't have much time at the moment, this is really more of a pre-release to address #40 and push some of the new features. I didn't make any changes that should affect stability, so you can use it as normal.
I'll include a list of changes in the next proper release.

New Features

New Features:

• realtime feedrate display in status bar
• show probe / limit pin state as overlay on the bottom
• added HeightMap minZ and maxZ display in "Probing" tab
• added "Debug Info" tab:
  • added show status lines option
  • added option to change console fade time
• improved heightmap autosizing from toolpath (now is accessible from a button in "New HeightMap" window)

Bugfixes:

• stopped assuming a default feedrate of 100mm/s (#35)

New Features and Performance Improvements

I have a new machine and finally found some time to add some new features:

bugfixes:

• fixed horrible performance with many short moves and high line throughput
• setting WCO with G10 P1 used work position instead of machine position
• modal words sent while jogging were interpreted normally (esp. G91)
• made gcode parser slightly more stable

new features:

• toolpath boundary
• added jogging modifier ctrl, enabled shift+up/down for Z moves
• feed/rapid overrides
• added option to pause streaming when M0/M1/M2/M30 are sent to grbl
• the probe pattern is now dynamic and supports custom axis weights (my machine has a heavy Y axis that jerks the table -> X axis can be prioritized)

Have fun and report any bugs here :)
Cheers!

Version 1.3.2

-fixed error for non-english systems (that use commas as decimal separator). See #30
-added catch-all exception handler that writes fatal exceptions to a log file

urgent bugfix

fixed newly introduced error when applying heightmap

only supports grbl 1.1

Update: added new Exception Handler for unhandled exceptions
This will only benefit few people, so I'll just add it as an extra zip file "OpenCNCPilot_1.3.1_EH.zip" instead of a new release.
If you are new here, use "OpenCNCPilot_1.3.1_EH.zip", as it will give more detailed info about fatal exceptions.
