Printer is Ender 3 Pro,running SKR mini E3 V.2.0 with TFT35 touch screen Issue: When connected to PC to run PID noticed issue with TFT35 not showing current temperature when PID is running. Screen is displaying indoor temp 24/0C After PID is completed the TFT35 start to show deccending teperature on the screen for extruder1

How to: Connect printer to PC. Connect printer to Pronterface. Run g code:

  1. M106 P0 S255 to turn on the first fan
  2. M106 P1 S255 to turn on the second fan
  3. Run PID autotune M303 E0 S240 C10
  4. PID autotune start
  5. Pronterface Software is reporting a temp rising from 24C to 240C
  6. At this time TFT screen is reporting only 24C indoor temp as long as the PID test is running. 7.After the PID test is completed TFT35 screen is starting to report decreasing temperature for hot end,so hot end is cooling down at this point.

What is expected: When printer is connected to PC and PID autotune is running, the temperature of the hot end needs to be displayed on the printer screen at the same time as it is reported in the Pronterface software.

Issue 2: Emergency shutdown is not working when activated,hot end and bed is still heating normally. How to: Turn on printer Heat up nozzle to 200 and bed to 70C Let temperature stabilize Activate emergency shut down from TFT screen interface The message is displayed printer halted on the screen Printer is halted but hot end and bed are still heating.

Issue: Hot end and bed are running still hot at set temperature. The power is not cut down on the hot end and bed after emergency stop is activated via TFT35 screen interface. What is expected: When printer is halted via screen interface the power to the hot end and bed is automatically turned off.

TFT35 is running latest firmware Mini E3 V2.0 is running configured marlin 2.0.7 Printer modifications: Control board SKR Screen TFT35

The problem with the temperature message has been fixed in the new FW to the TFT display. Stop problem: You activate Cancel GCode in the config.ini display for example: cancel_gcode: M104 S0 \ nM140 S0 \ nG28 XY R10 \ nM107 \ nM18 \ n
