I have a classic Ender 3 running Marlin-2.1.1 on a BTT SKR v1.3 board with TMC 2130 drivers. Wifi is connected with ESP3D on an ESP32-CAM board connected to a TFT port. The X endstop is on the left side.

When I send G28 or G28 X, the hotend does not home properly. Rather the hotend just moves a little to the right side (like 3 mm) and stops. So if I keep on sending G28 X, the hotend just moves little by little to the right side.

This indicates that the printer thinks the endstop is already triggered and is trying to back off to untrigger it, so that it can probe. If a minimal move to the right does not untrigger it, it gives up, assuming something is wrong with the endstop. Either your endstop switch is broken or it's not connected. A disconnected endstop switch will behave identically to one that's stuck down (open circuit).

  • Looking at the config file, the endstops are correctly configured (`XYZ_MIN_ENDSTOP_INVERTING`), so this answer is very plausible! – 0scar Mar 09 '23 at 08:25
  • Correct Endstop was broken and a new replacement fixed the issue. Thank you all for your help. – Hansa G Mar 10 '23 at 04:29
