Custom Post-Processor for GRBL based Openbuilds-style CNC machines, router and laser-cutting
Made possible by
Swarfer https://github.com/swarfer/GRBL-Post-Processor
Sharmstr https://github.com/sharmstr/GRBL-Post-Processor
Strooom https://github.com/Strooom/GRBL-Post-Processor
This post-Processor should work on GRBL-based machines
Changelog
22/Aug/2016 - V01 : Initial version (Stroom)
23/Aug/2016 - V02 : Added Machining Time to Operations overview at file header (Stroom)
24/Aug/2016 - V03 : Added extra user properties - further cleanup of unused variables (Stroom)
07/Sep/2016 - V04 : Added support for INCHES. Added a safe retract at beginning of first section (Stroom)
11/Oct/2016 - V05 : Update (Stroom)
30/Jan/2017 - V06 : Modified capabilities to also allow waterjet, laser-cutting (Stroom)
28 Jan 2018 - V07 : Fix arc errors and add gotoMCSatend option (Swarfer)
16 Feb 2019 - V08 : Ensure X, Y, Z output when linear differences are very small (Swarfer)
27 Feb 2019 - V09 : Correct way to force word output for XYZIJK, see 'force:true' in CreateVariable (Swarfer)
27 Feb 2018 - V10 : Added user properties for router type. Added rounding of dial settings to 1 decimal (Sharmstr)
16 Mar 2019 - V11 : Added rounding of tool length to 2 decimals. Added check for machine config in setup (Sharmstr)
: Changed RPM warning so it includes operation. Added multiple .nc file generation for tool changes (Sharmstr)
: Added check for duplicate tool numbers with different geometry (Sharmstr)
17 Apr 2019 - V12 : Added check for minimum feed rate. Added file names to header when multiple are generated (Sharmstr)
: Added a descriptive title to gotoMCSatend to better explain what it does.
: Moved machine vendor, model and control to user properties (Sharmstr)
15 Aug 2019 - V13 : Grouped properties for clarity (Sharmstr)
05 Jun 2020 - V14 : description and comment changes (Swarfer)
09 Jun 2020 - V15 : remove limitation to MM units - will produce inch output but user must note that machinehomeX/Y/Z values are always MILLIMETERS (Swarfer)
10 Jun 2020 - V1.0.16 : OpenBuilds-Fusion360-Postprocessor, Semantic Versioning, Automatically add router dial if Router type is set (OpenBuilds)
11 Jun 2020 - V1.0.17 : Improved the header comments, code formatting, removed all tab chars, fixed multifile name extensions
21 Jul 2020 - V1.0.18 : Combined with Laser post - will output laser file as if an extra tool.
08 Aug 2020 - V1.0.19 : Fix for spindleondelay missing on subfiles
02 Oct 2020 - V1.0.20 : Fix for long comments and new restrictions
05 Nov 2020 - V1.0.21 : poweron/off for plasma, coolant can be turned on for laser/plasma too
04 Dec 2020 - V1.0.22 : Add Router11 and dial settings
16 Jan 2021 - V1.0.23 : Remove end of file marker '%' from end of output, arcs smaller than toolRadius will be linearized
25 Jan 2021 - V1.0.24 : Improve coolant codes
26 Jan 2021 - V1.0.25 : Plasma pierce height, and probe
29 Aug 2021 - V1.0.26 : Regroup properties for display, Z height check options
03 Sep 2021 - V1.0.27 : Fix arc ramps not changing Z when they should have
12 Nov 2021 - V1.0.28 : Added property group names, fixed default router selection, now uses permittedCommentChars (sharmstr)
24 Nov 2021 - V1.0.28 : Improved coolant selection, tweaked property groups, tweaked G53 generation, links for help in comments.
21 Feb 2022 - V1.0.29 : Fix sideeffects of drill operation having rapids even when in noRapid mode by always resetting haveRapid in onSection
10 May 2022 - V1.0.30 : Change naming convention for first file in multifile output (Sharmstr)
xx Sep 2022 - V1.0.31 : better laser, with pierce option if cutting
06 Dec 2022 - V1.0.32 : fix long comments that were getting extra brackets
22 Dec 2022 - V1.0.33 : refactored file naming and debugging, indented with astyle
10 Mar 2023 - V1.0.34 : move coolant code to the spindle control line to help with restarts
26 Mar 2023 - V1.0.35 : plasma pierce height override, spindle speed change always with an M3, version number display
03 Jun 2023 - V1.0.36 : code to recenter arcs with bad radii
04 Oct 2023 - V1.0.37 : Tape splitting
Nov 2023 - V1.0.38 : Simple probing, each axis on its own, and xy corner, for BB4x with 3D probe, and machine simulation
10 Feb 3024 - V1.0.39 : Add missing drill cycles, missing because probing failed to expand unhandled cycles
13 Mar 2024 - V1.0.40 : force position after plasma probe, fix plasma linearization of small arcs to avoid GRBL bug in arc after probe, fix pierceClearance and pierceHeight, fix plasma kerfWidth
27 Mar 2024 - V1.0.41 : replace 'power' with OB.power (and friends) because postprocessor.power now exists and is readonly
30 Mar 2024 - V1.0.42 : postprocessor.alert() method has disappeared - replaced with warning(msg) and writeComment(msg), moved more stuff into OB. and SPL.
