  Wed Jan 26 18:38:29 CET 2022

  • Github: merged next branch into master.
  • Setup page with some notes about ddPrint on a Anycubic I3 Mega (S): http://ibrieger.de/ddprint-anycubic-i3.html
  • Uploaded new sensor housing stl's, reworked stl naming scheme (https://github.com/ErwinRieger/ddprint/tree/master/stl).
  • Added simple install script (ddinstall.sh) and a script for firmware flashing (dd-fw-upload.sh).
  • Added firmware blobs (firmware/build*/*.hex)
  • Include ProtoThreads library (github.com/benhoyt/protothreads-cpp.git) into ddPrint repository for easier firmware build.

• Github update: Python3 port and ddPrint on Anycubic I3M

  Committed the following changes into the next branch on github:

  • Python3 port of ddPrint:

    • Converting python files with 2to3 script.
    • Fix integer divisions.
    • Use bytes() and bytearray() instead of strings for binary data.
    • Converted scripts and 'ddtool' utility to use python3.

  • Ported ddPrint to Anycubic I3M printer:
    

    • Pin changes for anycubic i3m.
    • Add support for ATC Semitec 104GT thermocouple.
    • Rework temperature measurement: allow different thermocouple types for heated bed and hotend.
    • Homing: add support for additional Z1 stepper motor and endstop.
    • Homing: implement dual-z homing.
    • Adjust getendstops command for the additional Z-endstop.
    • Control mainboard cooling fan (anycubic i3m).
    • Changed initial baudrate to 500 kbaud, 1 Mbaud is to fast for Anycubic i3m.
    • Auto-baudrate: added new printer profile setting 'baudRateLimit' for the Anycubic i3m (it does not work with 1 Mbaud baudrate).
    • Rework and cleanup ddPrint scripts: Added workaround for a problem with the linux cp210x driver used for the Anycubic i3m (CP2102 usb-serial chip): avoid reset of printer on device-open (cp210x seems to toggle DTR line even if '-hupcl' is used).

  • Other changes:

    • Environment: renamed env. var $DDDEVICE to $DDPRINTDEV.
    • Firmware build: Set ARDUINO_PORT from DDPRINTDEV environment var.
    • Added new command "continuosmove" for testing, allow simple movements of the printer (without homing) for debugging/initial setup. Note: no acceleration and no endstop-check - dangerous.
    • Removed unused baudrate commandline switch.
    • Cleanup handling of printer-device ($DDPRINTENV).
    • Firmware: moved pins include files into its own folder.
    • Improved plot_mat_profile.py scipt: use python-argparse, display more information.

• Github: Merged next into master

  Merged next into master, biggest change: ported ddPrint to use python3.

• Changes on ddPrint *next* branch on github:

  Erwin Rieger • 01/17/2022 at 17:26 • 0 comments

  Thu Dec 30 14:53:31 CET 2021
  

  • Merged python3 port into next branch.
  • Restructured project, moved test gcode files into it's own repository: https://github.com/ErwinRieger/ddprint-test-gcode.
  • Build: cleanup Makefiles, added license and moved firmware Makefiles into its own folder. Moved common makefile stuff into makefile-include files.

• Project updates on github.com:ErwinRieger/ddprint

  Erwin Rieger • 12/21/2021 at 13:50 • 0 comments

  Documentation:
  

  • Describe material profiles in more detail.
  • Describe automatic material profile measurement, determine *into-air* and *printing* volumetric flowrate data.
  • Update section about temperature-limiter.
  • Update section about flowrate-limiter.
  • Added more pictures and data plots.

  Code fixes:
  

  • Auto-temp: fix "workingpoint" commandline parameter, it worked the wrong way.
  • Preload: test another way to compute amout of data to pre-download to the printer, simply count small moves.
  • Some cleanup.

• Some project updates on github.com:ErwinRieger/ddprint

  Erwin Rieger • 12/07/2021 at 09:59 • 0 comments

• Documentation update

  Erwin Rieger • 11/16/2021 at 00:28 • 0 comments

  Added explanatory asciinema screencasts for the following ddPrint commands:

  * ddprint getstatus (shortform: ddprint stat), https://ibrieger.de/ddprint-3d-printer-firmware.html#getstatus

• Page about ddPrint setup on Ender5 (pro)

  Erwin Rieger • 10/19/2021 at 20:35 • 0 comments

  Drafted a page with some notes about installing ddPrint on an

  Ender5 (pro): ibrieger.de/ddprint-ender-5.html.

• Merged next branch into master

  Erwin Rieger • 10/15/2021 at 16:48 • 0 comments

  Merged *next branch* into master with the following changes:
  

  Porting ddprint to Ender5 (pro):

    * Changes for the Creality melzi board (atmega1284p based).
    * Added thermistor table for epcos 100k ntc.
    * Declared IO-pins in firmware/pins_ender3.h
    * Rework homing:
      + use feedrate and direction for homing from printerprofile.
      + Move away from nozzle after z is homed (for printers that
        home at z=0. This is to avoid scratching over the bed when
        homing X and Y.
      + Homing: added "4 point mode" for ender.
    * Added new script *thermistor_table.py* to generate thermistor
      tables (c-code).

  Other changes:

    * Host: rework *getstatus* and *mon* commands.
    * Host: filament profile measurement:
      + measure2: increase printing speed with fixed
        temperature while monitoring feeder grip.
      + measure2: changes to reduce heating effect of
        heated bed, start measurement on fifth layer.
      + specify minimum grip value on commandline (instead of
        hardcoded value).
      + write measured material profile to ./mat-profile2.add.
    * Host, *removefilament* command: changed feeding
      sequence to avoid filament plug.
    * Host, Experimental: added *reconnect* command.
      To reconnect to a running printer, works after
      download is complete, but not if disconnected
      while downloading stepper data.
    * Host: Added *ddprint version* command.

    * Firmware: cleanup flowrate measurement,
      measure short moves, too.
    * Firmware: added CmdGetVersion command.
    * Firmware, Makefile: new target *make gitversion.cpp*
    * Firmware: set printer state to idle if steppers are
      disabled (cmd *disablesteppers*).
    * Firmware: Update to SdFat-1.1.4 library (USE_SD_CRC enabled).
    * Firmware: Rework mass storage erase: new commands CmdGetCardSize
      and CmdErase. Call erase before printing.
    * Firmware: Sd card init: retry up to 5 times.

    * Many smaller fixes/improvements

• Reworked flowrate sensor housing

  Erwin Rieger • 10/15/2021 at 13:02 • 0 comments

  * Rotated design to shorten filament path between
    feeder gear wheel and rotary encoder for better response.
  * Made it i bit more compact.
