Version 3.3 Config B

[Modix3D]

Config B update

Configuration B is our first release targeting some of the new features that RepRapFirmware 3.3 brings us. RepRapFirmware uses functionality such as conditional gcode that allows you to use conditional statements to execute moves.

The main point of this update is to resolve some long-standing bugs with the Z-datum error, as well as general usability upgrades.

We are also updating the naming scheme for the configuration updates. The naming scheme will now depend on the compatible RepRapFimware version, followed by a lettered schema to indicate the variant of the configuration and macro files.

For example:

Version 3.3 Config B

This is compatible with RepRapFimware 3.3, and it's the second update to the configuration files (Config B)
If an update to RepRapFirmware happens, and the configuration files also match, this will be Version 3.4 Config A for the first release.

Config B update notes

Homing, tilt and bed calibration

• Improved the homing and calibration files to properly load and unload the heightmap, and properly establish the Z=0 datum
• Adjusted the homing position to be in the front left of the build area for all printers.This way the front left corner (which is X0, Y0) now also has Z=0
• Updated the homing, tilt and bed calibration files to reference the min/max position, rather than a fixed number, so they are usable across all printers.

Adjusted the pausing and resume functionality

• Adjusted the resume.g to be a bit slower speed and changed the m116 S value from S7 to S3, to be slightly closer to printing temperatures
• Changed the pause.g to deselect the used printhead, so that it cools down during the pause

Added filament-error0.g and filament-error1.g

• These trigger if the primary or secondary filament sensors (or clog detectors) trigger. This allows you to differentiate between a user-initiated pause, or a pause caused by a filament runout error.
• The messages differentiate between the two tools

Added stop.g functionality

• Allows you to use M0 in the end-gcode of your print, allowing for more unified end-gcode. It has been populated by our suggested end-gcode.

Mesh bed and adjustments:

• Adjusted the M557 parameters, now uses P for spacing instead of S. it uses between a 8x8 (for 40) to 30:10 (180x) to 15:15 (meter) grid instead of a set distance. Changed the mesh area to be -1mm from each edge
• Adjusted the M376 H value from H10 to H100, to better work with the large bed size Modix printers.

Config.g adjustments:

• Increased the motor idle factor for the motors to be 50%
• Removed the U axis, instead set up the X axis to use two endstops.
• Added names to the blower fans and LED

Config_probe.g is a new file. This is where the BLTouch related settings are now loaded in. This allows multiple files to load in the correct BLTouch data, preventing the possibility of the BLTouch data not being properly loaded

Macro B update notes

• All macro files are now identical across all printers.
• Changed the order of the calibration macros to be the same for all printers. It now goes probe -> Z-offset -> tilt -> bed compensation
• The LED on and off macros are now LED toggle, which toggles the LED between on and off.
• filament change macro has been updated, slightly lower retraction/extrusion speed, and uses relative extruder movements. Also properly re-selects the tools after pausing
