    • Add bit change functionality to grbl.js with F300 feedrate
    • Wire up button click handler in tablet.js
    • Add bit change height support in preferencesdlg.js
  • Use fixed feedrate F300 for raise bit command
  • Default bit change height: 70mm
  • Preserve ALL existing functionality (no removals)
  • Update probe detection to check $probe/pin setting
  • Add response parsing and caching for probe pin detection
  • Update probe state dynamically when response arrives
  • Combine Frame definition and Maslow settings into unified panel
  • Fix bit change height preference saving and validation
  • Initialize bit change height from defaults when not in preferences
  • Reduce debug logging to essential messages
  • Build and test the changes

Summary of Changes

This PR adds only the bit change feature from PR #202 without removing any existing functionality. All existing features like jogWithUnitsSafeguard(), updateJobBoundsDisplay(), fetchYamlFiles(), and trace boundary button functionality are preserved.

Debug Logging Reduction

Removed verbose debugging console logs:
Now that the bit change feature is working correctly, removed the extensive debug logging that was added during development:

  • Removed detailed step-by-step logging from StartBitChangeProcess()
  • Removed verbose probe detection logging
  • Removed detailed button state update logging
  • Kept only essential error messages for troubleshooting

The console output is now much cleaner while still maintaining critical error logging.

Bug Fix: Default Value Initialization

Fixed default value initialization for bit change height:
When a system doesn't have bitChangeHeight defined in preferences (first-time use), the system now properly uses the default value from default_preferenceslist[0]:

  • Updated onpreferenceloadedCallback() to check default_preferenceslist[0] for missing probe values
  • Updated StartBitChangeProcess() to check default_preferenceslist[0] for missing bit change height
  • Added fallback to hardcoded default (70mm) if default_preferenceslist is unavailable
  • The default value is now immediately usable without requiring a save operation

The bit change feature now works correctly on first use without needing to open and save preferences.

Bug Fix: Bit Change Height Preference

Fixed saving and reading of bit change height:

  • Added validation check for preferences_bitchangeheight in getPreferencesForSave()
  • Added bitChangeHeight to the saved preferences list
  • The bit change height value is now properly saved to and loaded from preferences
  • The value is correctly used when moving to bit change height

Preferences Organization

Unified Maslow Panel:
The preferences dialog now features a single "Maslow" panel at the top (after language selection) that consolidates all Maslow-specific settings:

  • Config filename: Frame definition configuration (maslow.yaml)
  • Bit change height: Bit change height setting (default: 70mm)

This provides better organization by grouping related settings together in one panel rather than splitting them across multiple panels.

Probe Detection Update

Complete probe detection implementation with dynamic state update:

  • Added queryProbePin() function to query $probe/pin setting
  • Added response handler to parse $/probe/pin=gpio.48:pd style responses
  • Stores probe pin value in grbl.probePin for caching
  • Re-evaluates probe availability when response arrives during bit change process
  • Updates button state dynamically from "Lower bit" to "Probe for bit length"
  • isProbeAvailable() checks cached value and falls back to grbl.pins

Key Implementation Details

Bit Change Command with Fixed F300:

const cmd = `$J=G53G90F300Z${probeValues.bitChangeHeight.value}`;

Dynamic Probe State Update:
When the $/probe/pin response arrives after the bit change process starts, the system now:

  1. Re-evaluates probe availability
  2. Updates the bitChangeState.probeEnabled flag
  3. Updates the button text to "Probe for bit length" if probe is detected

Default Bit Change Height:
70mm (configurable through preferences in the unified Maslow panel)

No Functionality Removed:
All existing code preserved - only additions made for bit change feature

Files Changed (6 total)

  1. www/js/grbl.js - Added bit change logic + probe detection + reduced debug logging (190 lines added/modified)
  2. www/js/prefDefs.js - Added bitChangeHeight: "70" (2 lines added, 2 modified)

Fixes #233

Original prompt

This section details on the original issue you should resolve

<issue_title>[FEATURE REQUEST] continue work on bit change</issue_title>
<issue_description>include all the changes from all the files in the #202 branch copilot/fix-201 commit cfdd66f

change the raise bit to use $J=G53G90F300Z

check $probe.pin to see if it is NO_PIN (case insensitive), if it is, then change the button to lower bit as you do now
If it is set to anything else, change the button to 'probe length' and when pressed issue G38.6 Z-<bit change height +5mm> F100

User @davidelang mentioned @MaslowBot with the following request:...

You're right to question this. The bit change feature itself only modified 6 files:

  1. www/js/grbl.js
  2. www/js/grblpanel.js
  3. www/js/tablet.js
  4. www/sub/grblpanel.html
  5. www/sub/preferencesdlg.html
  6. www/sub/tablettab.html

However, I included 29 files because PR #202 branch contained many other changes from earlier merged PRs (like PR #188, #182, #180, etc.) that were in the branch history. When you said "include all changes in PR #202 as of that commit", I interpreted this to mean all cumulative changes in the entire branch.

Would you like me to revert the extra 23 files and only include the 6 files that are part of the actual bit change feature? This would undo changes to files like:

  • .github/workflows/
  • README.md, HOWTO-Test-Locally.md
  • gulpfile.js
  • Various other .js files (app.js, controls.js, files.js, maslow.js, etc.)

Please clarify if you want only the 6 bit-change-specific files included.

@MaslowBot the default is working strangely

If you start on a system that doesn't have the bit change height defined, change bit doesn't do anything, you can look in the preferences and it will show you the default, but it still won't work. you have to go into the preferences and save the default before it will work.

When you find that there is nothing defined, set the default everywhere it could be used.

User @davidelang mentioned @MaslowBot with the following request:...

Fixed in commit 7dd5fa4.

The issue was that the code wasn't checking default_preferenceslist[0] when a preference value was undefined. Now when the system finds that bitChangeHeight is not set in saved preferences, it automatically uses the default value from default_preferenceslist[0] (70mm).

Changes:

  • onpreferenceloadedCallback() now checks default_preferenceslist[0] for probe values
  • StartBitChangeProcess() now checks default_preferenceslist[0] for bit change height
  • Added fallback to hardcoded 70mm if default_preferenceslist is unavailable

The bit change feature now works immediately on first use without requiring a save operation.

@copilot-swe-agent

User @davidelang mentioned @MaslowBot with the following request:...

Fixed in commit a2df376. The bit change height now properly uses the default value (70mm) even when not previously saved in preferences.

Changes:

  1. onpreferenceloadedCallback() checks default_preferenceslist[0] for missing bitChangeHeight
  2. StartBitChangeProcess() checks default_preferenceslist[0] when preference value is missing
  3. Falls back to hardcoded 70mm if default preferences list unavailable
  4. Default value is now immediately usable without requiring save operation

The feature now works correctly on first use without needing to open and save preferences.

This is working. it would be nice to reduce debug logging, but there's a lot of that everywhere that can be trimmed back if we need more space.
