Extract temp to external display

tecno

Cables are inserted OK . My menu folder is like yours.

Did you ever load in FW in your display board?

I do not use this type of display, but maybe this will help. There are also versions (think from MKS) where the plug must be turned 180 ° .

@DIY-O-Sphere

Tried those settings also, next to be a pin detective and see if there is something in wireing.

Thanks for help, appreciated.

Will try more tomorrow.

Pinout seems to be OK.

Is this display 5V and not compatible with Mini5+ ?

tecno

Why is there no DISPLAY in the left menu?

@tecno
It's under System. Have a look at the screenshot I have posted yesterday.

@tecno did you get it working?

@dc42

Unfortunately no

Is there anybody out there (Pink Floyd) that can help me?

@tecno
Can we have some picures of the wiring?

@DIY-O-Sphere
Std 10 pin cables Exp1 to Exp1 and Exp2 to Exp2

Had a look again on how cables are keyed as I did not get any life at all. F-ng assembly from the chinese as turning cables 180° I now get backlight and encoder lit up but nothing on screen.

@tecno
As far as I can tell from the picture, turning is required for exp1 but not for exp2.

@tecno
Perfect...

So now my mini 12864 is working

Next is to get my old RepRapDiscount to work. So how to read the silkscreen on board as regards cable keying?

@DIY-O-Sphere
I interpret the white markings as the cable keying and that is 180° yet another twisted cable, right?

@tecno please note, the RepRapDiscount controllers require 5V signals, so they are unlikely to work reliably with the 3.3V signals from the Duet 3 Mini. That's why we suggest the Mini 12864 display.

@dc42
Yes I am aware of that. I assume only EXP1 needs level shifters on LCD_CS/SCK/MOSI ?
