@thisiskeithb is this related with that other LCD we were working?

[thisiskeithb]

is this related with that other LCD we were working?

I was using an MKS Mini 12864, not the Fysetc Mini.

[sjasonsmith]

There are actually two completely unique issues reported here now.

The original report is an MKS_GEN_L with a RepRapDiscount Full Graphics.

[sjasonsmith]

I have the hardware for both of these...I guess I'll assign it to myself so I remember to try them.

[rhapsodyv]

@thisiskeithb could that that contrast setup what we removed, affect fysetc mini? I will take a look if the share the same code.

We removed that #if

void MarlinUI::init_lcd() {
   #if DISABLED(MKS_LCD12864)

@ase95 your configurations boot just fine for me, on an MKS Gen-L V1.0 with a BigTreeTech RepRapDiscount Full Graphic Smart Controller. I changed nothing, and used them on top of the current bugfix-2.0.x branch, commit 6f8282f.

[sjasonsmith]

@nvumnov I agree that something seems wrong with the board and LCD you are using. I can't get them to work either.

Please open a new issue for your problem. It isn't related to the original issue, since it is completely different hardware.

i tried redoing the config file but same problem occurs... i can't understand what im doing wrong...
also tried with the "premade" config download from marlin without chaning anything ,and still doesn't work...

Any idea on why is it not working for me ? i even tried using Atom instead of VS, marlin 2.0 and 2.0bugfix

@ase95 as a test (do not run like this)
disable #define USE_WATCHDOG in Configuration_adv.h
See if anything changes

[boelle]

@ase95 did you try what @ellensp suggested?

[ase95]

i've not tried it. for now i'll settle for the 1.9 version and i'll wait for new update of the 2x to see if it get fixed

I downloaded the latest official version 2.0.7.2 today. The problem is the same as @ase95. When I turn on the switch, Marlin restarts repeatedly. My board is MKS_SGEN_L, and the display is MKS 12864A+3DTOUCH. I found that 3D TOUCH conflicts with MKS12864A. I disable BLTOUCH Marlin to start normally, or disable #define MKS_LCD12864, and connect PC with Pronterface to control the printer normally. I tried to disable @ellensp suggested #define USE_WATCHDOG with the same result. This problem has always existed from 2.0.6.1 to 2.0.7.2. I hope the Marlin team can solve this problem. Now I can only use 2.0.5.4 to wait for the latest update, thanks @boelle

My board is MKS_SGEN_L, and the display is MKS 12864A

@nongcj This issue is for the Gen-L + RepRapDiscount Full Graphic LCD and is unrelated to your hardware combo.

MKS has documented the A variant to only be compatible with 8bit/AVR boards. You’d need to use the B version on 32bit.

@ase95: bugfix-2.0.x is updated daily, but if you don’t want to try what has been suggested here, I’ll close the issue for now.
