Marlin 3D Printer Firmware for the Tevo Black Widow

Marlin specific documentation can be found at The Marlin Documentation Project. Please test this firmware and inform us if it misbehaves in any way, volunteers are standing by!

Marlin for the Tevo Black Widow is base off Release Candidate -- Marlin 1.1.0-RC8 - 6 Dec 2016 For the Marlin specific release notes refere to the Marlin RC brach located here: https://github.com/MarlinFirmware/Marlin/tree/RC.

Tevo Black Widow Specific Changes:

Version 1.1.0-RC8 04-15-17 Version 4.0

  • Fixed a bug that prevented DISTINCT_E_FACTORS from working properly.
  • Fixed a bug where the auto level probe would try to probe off the rear of the bed if it had a positive Y offset.
  • Add the new configuration files as outlined in the community guide.

Version 1.1.0-RC8 03-02-17 Version 3.2

  • Added replaced "Babystep Z" in the main menu during a print with "Live adjust Z" if using an auto leveling probe. Live adjust Z modifies the Z offset in realtime and saves the eeprom on exit.
  • Removed unused example configurations.
  • Add status_printf function for status line of display.
  • Added hotend name to heating status indicator.
  • Applied a fix to display E steps with a M503 if more than one extruder configured.
  • Added Dariy & Simon thermistor table and set it to be used as the default for the hotend.

Version 1.1.0-RC8 02-07-17 Version 3.1

  • Made the cooldown option when stopping a print from sd card a configurable option in Configuration.h. By default this option is enabled. Comment out #define SD_STOP_AUTO_COOLDOWN located in the Extra Features section of the configuration.h to disable this feature.
  • Apply some fixes to the manual bed leveling routine that could cause the homing prompts to hang.

Version 1.1.0-RC8 01-16-17 Version 3

  • Improved display responsiveness.
  • Changed default speed and acceleration settings to make them more conservative to prevent stepper skipping.
  • Included a bug fix for BLTouch see: MarlinFirmware/Marlin#5650
  • Changed menu item selection from hollow box to inverted box.
  • Added a confirm to stop print when printing from SD card.
  • Fixed a bug in the stop print function by adding code to shutdown the hotend and heatbed.
  • Changed the menu beep duration from 100ms to 10ms.
  • Default to single bed probing when auto leveling with G29 (double touch is a waste of time see: https://goo.gl/fzHGji).
  • Updated GCode scripts to keep print head in bounds (some users can't take the print head to a negitive location).
  • Updated Conditionals_post.h so the #define XXXXXX_PROBE_BED_POSITION statements are no longer needed.
  • Enabled the LCD info menu.
  • Changed the move axis menu to select the axis first and distance second.
  • Relocated the move axis menu item to the top of the prepare menu.
  • Added filament change option to the prepare menu.
  • Reduced the duration of the filament change beep from 300ms to 20ms.
  • Changed the code to always show the BLTouch reset option in the prepare menu.

Version 1.1.0-RC8 12-27-16 Version 2

  • Added "Babystep Z" to the Main Menu when performing a print. This allows the user to quickly access the the realtime z height ajustment.
  • Changed BABYSTEP_MULTIPLICATOR to 10 as the default of 1 is way to slow to make noticeable corrections.
  • Lowered LCD_UPDATE_THRESHOLD from 135 to 50 to improve display response time.
  • Updated the above gcode start script to a version that is more friendly with corner clamps.

Version 1.1.0-RC8 12-22-16 (Initial Release) Version 1

  • Removed Tevo boot screen to speed up the marlin boot process.
  • Added "#define TEVO_BLTOUCH" to the Configuration.h and associated #ifdef to probe support sections to enable BLTOUCH support.
  • Added support to drive the extruder cooling fan on port E1 of the MKS Gen motherboard.
  • Changed extruder fan speed to 80% to reduce noise and vibration, see the file "Configuration_adv.h" at the line "#define EXTRUDER_AUTO_FAN_SPEED 204 // == 80% to reduce noise"
  • Increased the display menu timeout from 15 seconds to two minutes by changing the line "#define LCD_TIMEOUT_TO_STATUS 15000" to "#define LCD_TIMEOUT_TO_STATUS 120000" in the file ultralcd.h.
  • Used a combination of settings derived from the offical Tevo port of the Black Widow firmware and currently released community firmware releases.
