Firmware for Marlin 2.0.x and Creality default LCD

https://github.com/ginge/Marlin/tree/CrealityDwin_2.0 Repo containing a rewrite of the LCD interface to allow Ender 6 to work with stock LCD

General Notes

• EEPROM is stored on the SD card. If you change the SD, make sure to copy it over
• Tighten all of the rollers before use. at high speed the carriage can vibrate if it is fractionally loose

LCD:

DWIN DMT48270C043_06WT - https://www.aliexpress.com/item/1005001962148737.html?spm=2114.12010612.8148356.23.51f46c08lNXdFA DGUS mode. Mostly compatible with Ender 5 plus commands. No LCD Source available.

• https://github.com/CR6Community/CR-6-touchscreen <- Re-purposeable to new orientation and layout

BL Touch

• Just buy a plain one, no kit required. Ender 6 has mounting brackets
• required 1m of ribbon cable & conector. Get extension.
• Ender 6 has a Molex Picoblade 1.25mm pitch connector. - https://www.ebay.co.uk/itm/Molex-PicoBlade-1-25-micro-connector-2-3-4-5-6-Pin-leads-100mm-28-AWG-wire-PCB/232695637343?hash=item362dbda55f:g:vHoAAOSwWmNapoY1
• Levelling: z-Offset problem:
  • When levelled and aux levelling is done PRESS HOME TWICE. This saves the EEPROM.

Firmware

• Marlin confs - https://github.com/MarlinFirmware/Configurations/tree/import-2.0.x/config/examples/Creality/Ender-6

Cura 4.8 config

• Copy all files relating to ender from their slicer to Cura.
• I was using flatpak so added them to ~/.cura folders
• Info from here - https://forum.creality.com/topic/1172/creality-ender-6-cura-slicer-profile/3

To Do

• Z axis leadscrew replace with finer pitch
• better filament roller support that doesn't rub
• extension for the filment sensor to align it with the feeder
• a clip to hold the bowden so it doesnt dnag on the blue connector
• jog wheel
• better PSU
• USB connector is broken out with an extension cable

Addons

• Fan Shroud - https://www.thingiverse.com/thing:4698226
• x/y Chain - https://www.thingiverse.com/thing:4731935
• cable trunk Strain relief - https://www.thingiverse.com/thing:4690585
• head strain relief - https://www.thingiverse.com/thing:4695820
• filament bearing holder - https://www.thingiverse.com/thing:4659228
• Orion quiet fan - https://www.digikey.com/en/products/detail/orion-fans/OD4010-24HB/2621113?fbclid=IwAR3BVuU-d9iysA3kckwqtj83w1VciwGTxTPJBJn7Hn-ydM5ehei6z_Pmev0

LCD firmware hacking

• https://github.com/b-pub/dwin-ico-tools

• Creality CR6SE firmware dwin code ported to ender 6 (Y) - mostly working.

• re-position all ui elements for correct orientation (20%)

• Sniff/map all stock LCD commands (N)

• Able to use stock LCD (Kinda)

• DWIN code applied to lcd (N)

Issues:

• There are some commands that are not mapped
• you get stuck in screens

DGUS LCD Editor notes and gotchas

DO NOT overlap VP or SP areas.

VP: memory address for the control data. uint16.

• Text control and text digits are different. High and Low byte of the u16 data are 2 characters.
• Example text control. Text length 16 characters. VP Address: 0x5000. End Address: 0x5008

SP: Memory address for runtime configuration of controsls. This is optional

• SP addresses for each control should be placed in VP memory space.
• Ensure the control's SP size is accounted for when laying out memory

Curves:

• Occupy 0x1000 - 0x4000 when all 8 channels are used
• Channel 0: 0x1000 - 0x7FFF
• etc

New Screens:

• The BMP file must be prefixed with the page number. The firmware burner ont he LCD uses this to store the bmp in the correct memory page
• e.g. 01_page1.bmp
• bmp files MUST be 24bit

Saving changes:

• Save the project
• Click Export
• Copy the changed filed to DWIN_SET folder on the sd
• The lcd doesn't understand non ascii characters the editor generates, so:
• rename 13{blah}.bin to 13a.bin
• rename 14{blah}.bin to 14a.bin

Flashing:

• The SD card must be FAT formatted
• 4k sector size IS IMPORTANT!
• There is no need to apply all of the files on each flash. Putting just the bin files on there will flash just those etc.
