Duet 3 mini Menu Files
-
First of all big thanks for the Hard work with this new board.
I have set my duet mini up On my Ender 3 . The only bit i cant get running is the LCD.
I have the Menu Directory full of the requied files. And i have M918 set in my config.g
But DWC dose not have a menu section and the LCD is blank only the back light working.
Used to work fine with the Meastro running 2.3
Any ideas
Thanks

Playing with the display is on my list to do. I'll let you know what I find.
How did you connect the display to the board? Same pinout as with the Maestro?
-
Thats the odd bit. On the Maestro you need turn the plugs around on the display.
I found i had to put them back the correct way before the screen lights up. -
I'll have to double check. I use a Paneldue so I hadn't been using the stock display, but as part of the mini5 guide I'll get it up and running.

install this example menu in the menu directory on the sd card

@lodger, please check that you are running DWC 3.2 and RRF 3.2. Also that you have enabled the display using an appropriate M918 command in config.g.

Mornings,
Right i have double checked i am running up to date RFF and DWC i have even update the wifi server . I have all the menu files correct in the Menu Directory.
I also have:
M918 P1 E4 F2000000 ; configure direct-connect displayIn my config.g
So i am a little lost now.
I dont know if it help but my Diagnostic File say " LCD is idle in state(s) 0"

It's called "Display and should be just above "Filaments".

Having re done a firmware update this morning I now have display section showing all my files correct..
Running a M918 in the terminal reposts correctly.
So now i am thinking it is a wiring issue. I will look more into it later . The boss is telling me i have to do house work first... : ( -
Ok Have been playing a bit . And i have the FYSETC Mini working fine . but not the ender 3 display.
I am guessing the Enders display is not ST7567 controller. -

I am guessing the Enders display is not ST7567 controller.Correct, the Ender 3 uses a ST7920-based controller, which is P1 in he M918 command, not P2.
Almost all the ST7920-based controllers I have seen are designed to work with 5V signal levels, although I have heard of similar displays working with 3.3v signal levels at reduced speed on other controller boards.
A final complication is that the pinout is different from the Mini 12864, so you would need to make up a special cable, or else modify the display.

Thanks Dave.
I am liking the mini Lcd so will print some thing up and use that.
I will sit down next week when i am at work and bored to figure out a lead to get the Enders Display working. If it will work being 5v. If not i will try and find a replacement.I think a lot of folks will want this board on creality marchines.
-
@Veti Had you gotten the Ender 3 display to work with the Mini5+?
-
i have not tried it.
-
just tried connect the ender 3 one and a standard 12864.
all i get is a high pitched noise from the buzzer. cant test more or my neightbours will be annoyed.
no display output.
-
same here.
-
I did connect it up correct using jumper wires to get the correct pin outs .
But still have no success. I did not get much time to play more as the printer is at work. and i was busy.I do think it is 5v issue but i will try mess more next week. as sometimes you can see some txt and the screen flashes on and off i bit.
On a side note i have found a larger ST7567 controller based RGB Screen .looks the same layout and size of the Enders. I have ordered it and will report back if that works.
-
@lodger try reducing the SPI speed. To something like F100000 (add that to the M918)
-
Here are some notes I made when I was looking at this:
- EXP2 is the same on the Mini and the ST7920 display but reversed between them.
- EXP1 is also reversed but has the following additional changes
- The 3 Mini has LCD_A0 where the RRD display expects CS. This is handled in firmware - the firmware uses A0 as CS when a type 1 display is configured in M918.
- The Mini has LCD_RST (which the Mini just ties high through a pullup resistor) where the type 1 display expects SCLK
- The Mini has the CS pin where the type 1 display expects MOSI
- ENCA and ENCB are also swapped, but that doesn't matter, you can change the direction in the M918 command
So I think the easiest way to drive the display would be:
- Reverse the connectors at one end of each cable
- Cut the conductors in the EXP1 ribbon cable that carry LCD_RST and SPI2_CS2 from the Mini to wrong pins on the display
- On the display add links to carry MOSI and SCK from the EXP2 connector to the correct pins on the EXP1 connector
I have not tested this.
