Printer LCD unresponsive after flashing

zogthegreat · 12 June 2022 14:02

Hi everyone!
I’m on an Ender 3 Pro with an SKR Mini E3 v3.0 controller and OctoPi. I just flashed my printer with the latest firmware on the site. After flashing, the LCD loads slowly,

Marlin loading slowly

Also, the LCD becomes unresponsive and I can’t use the dial to move through the menus. When I reflash with the stock BTT firmware, everything goes back to normal.

Any suggestions to what I’m doing wrong?

Thanks!

If you insert a correctly formatted SD Card into the printer, does the problem go away?

Yes, the format of the card doesn’t seem to be the issue. I can use the same SD card to flash the stock firmware from the BigTree GitHub repo and everything works as it should. It’s when I flash with the firmware from this site, it goes buggy.

I just tried compiling the firmware myself using Bugfix 2.1.x. I had the same problem and asked about it on reddit. Apparently, this is a bug in Marlin 2.1.x, I filed a bug report on github.

[EDIT] Apparently, this is an existing bug:

github.com/MarlinFirmware/Marlin

[BUG] LCD freezes/very sluggish after upgrade if SD card is left in the mainboard (continues #24301)

Bug: Confirmed ! C: LCD & Controllers F: SD Card Printing

### Did you test the latest `bugfix-2.1.x` code? Yes, and the problem still exi…sts. ### Bug Description With 3e9fb34892e85bc4069acf5baddbf12d6cd47789 still, the LCD freezes, or at least gets very sluggish. It worked fine with 2.0.9.3. ### Bug Timeline Since 15b6159f6af740f17db2dc8815697759c714cc12 it is broken. 3e9fb34892e85bc4069acf5baddbf12d6cd47789 did not fix. ### Expected behavior I expected the LCD to render quickly and be able to navigate through all menus. Turning the knob clockwise or counter-clockwise would immediately change feed rate. ### Actual behavior Depending on the boot sequence it will either freeze completely, or be very sluggish. The info screen renders in more than 15s per half. The wheel button seems to not be able to open the main menu. Turning the knob clockwise or counter-clockwise would immediately change feed rate affects the feed rate, but it takes a long time for the number to update. ### Steps to Reproduce 1. Compile bugfix-2.1 (3e9fb34892e85bc4069acf5baddbf12d6cd47789) with the given configuration files. 2. Use a LPC1769 board (tested with MKS sgenl v2) with a RepRap Full Graphical Display and flash the firmware. 3. LCD freezes. ### Version of Marlin Firmware bugfix-2.1 (3e9fb34892e85bc4069acf5baddbf12d6cd47789) ### Printer model Modded Ender 3 ### Electronics MKS SGENL v2, Discount Full Graphic Smart Controller ### Add-ons EZNEO, EZABL, UART based serial connection ### Bed Leveling ABL Bilinear mesh ### Your Slicer Cura ### Host Software _No response_ ### Other things to include - [X] A ZIP file containing your `Configuration.h` and `Configuration_adv.h`. - [ ] Log output from the host. (`M111 S247` for maximum logging.) - [X] Images or videos demonstrating the problem, if it helps to make it clear. - [ ] A G-Code file that exposes the problem, if not affecting _all_ G-code. ### Additional information & file uploads ![image](https://user-images.githubusercontent.com/138827/172396624-262bb4cd-6f0e-4ebe-8451-cd73e9145fd7.png) (photo taken this morning) [configs.zip](https://github.com/MarlinFirmware/Marlin/files/8853725/configs.zip) ![image](https://user-images.githubusercontent.com/138827/172396939-5e136f3b-f97f-4890-b861-eb58f1a66d77.png)

Thanks for doing this - I know there was initial work done to try and fix.

I’ve imported the PR linked in that - as apparently it works around the issue - until a proper fix can be obtained.

The custom builders have this patch applied now - and I’ll have to re-run the nightly builds again to incorporate it soon.

I tried a custom firmware this morning, but it seems buggy. When auto homing, the axis’s move VERY slowly. With a standard firmware from this site, everything seems to work properly.

I also pulled Marlin from GitHub this morning and compiled it. This build still has the bug, my LCD went slow and I was unable to get into the LCD menus. I reflashed the standard firmware from this site and the problem went away. I dug into the repo, only the “gcode” and 'inc" have been updated, everything else hasn’t been updated for about a week or more.

Since you said that your pulling from the same repo, not sure why my build came out with the bug. I might have to wait until they update again to try rebuilding my own firmware.
