need help with Tornado with Marlin 1.1.9
January 21, 2020 02:20PM
I had a driver fail and had to buy new ones. So, I upgraded drivers to the TMC2208's and I upgraded the firmware to the 1.1.9 version. However, upon flashing the display screen comes back all garbled. Can someone please help me modify 1.1.9 to get it to work it would be greatly appreciated. Thank you in advance

Did you set up your configuration.h file with the new install?
If not, do a setting-by-setting compare with your old firmware and 1.1.9 and move your settings over. Make sure your stepper drivers microstepping matches firmware settings.
Make sure you have 1.1.9BF, there are issues reported with the "normal" 1.1.9.

The old firmware was 1.0.0. I followed as much as possible line by line in Config.h and Config_adv.h I downloaded the 1.1.9 bug fix, I can upload the Config.h and config_adv,h if someone could help

You need to add some delays to wait for your slower screen.

Add these lines to Configuration.h or your motherboards pins.h file

#define BOARD_ST7920_DELAY_1 DELAY_NS(125)
#define BOARD_ST7920_DELAY_2 DELAY_NS(125)
#define BOARD_ST7920_DELAY_3 DELAY_NS(125)
