The 5A power in provides power to: fans hotends vin (atmega2560 power supply) and stepper motors If you remove D1 then the mega is safe from getting to much voltage. but what of the fans or the hotend? You don't have to replace the 11A fuse if your not putting any power into that circuit. You may want to take look atby Dust - RAMPS Electronics
There should be no need to use the reset button. The CH340 DTR line is connected to avr reset, avrdude knows to assert this line to reset the controller to start upload. This can bee seen on the last page of the circuit diagram You either have a hardware fault or the boot loader has been damaged, Install stock atmega2560 boot loader, using a avrisp. see as one example on how to do this.by Dust - Firmware - mainstream and related support

I cannot replicate this issue using arduino ide or platformio. Best guess, you have defined something else to use the encoder pin 35 or its a hardware fault. Test your hardware withby Dust - Firmware - Marlin
You should use Platformio under vscode, its is 100x faster to build and uses correct libraries automatically.by Dust - Firmware - Marlin

STM32F103C8 officially only has 64K of flash and 20K of ram, this is insufficient for Marlin 2.1.x (I suspect Marlin 2.0 will be the same) A minimal build with the added STM32F103C8 build environment errors with `FLASH' overflowed by 22472 bytes If you force it to use 128k (ie make it think its a STM32F103CB, as some actually do have the extra flash ) it will build RAM: [==== ] 36.6by Dust - Firmware - Marlin

@trieudung That is not an error Its a warning. That you have no screen or HOST_PROMPT_SUPPORT or EMERGENCY_PARSER or any other way to give feedback enabled The full thing is #warning "Your Configuration provides no method to acquire user feedback!

dual x is not going change anything accuracy wise. When you enable a driver type X2 marlin auto allocates the first unused E as X2, so the first X is plugged into X plug and the X2 is plugged into E0 or E1 plugs (what ever is still un allocated) (unless you have changed the pins files to explicitly define the X2 pins)by Dust - Firmware - Marlin

with TMC2209's on BOARD_BTT_SKR_V1_4_TURBO you must remove the diag pin from the stepper driver when using endstop switches you have #define DIAG_PINS_REMOVED but did you actually do it?by Dust - Firmware - Marlin
Your config says you don't have a Z-endstop, your using a probe. So you don't get a z_min in the endstop listing. "Nozzle temp is reading 0/0 (zero)" on a BOARD_BTT_SKR_V1_4_TURBO this is normally caused by having a dead ADC pin.. The ADC pin on these boards are sensitive and can only take 0 - 3..3 volts, sadly when the hotend develops a fault it often sends 12v to this pin.by Dust - Firmware - Marlin
Has anyone got a Anycubic kobra plus and could measure the hotend to extruder PTFE tube length for me? Just the visible length from fitting top to fitting top is fine, I can add the internal lengths Ball park from their replace the hotend video its about 400mm long, I'm trying to fix up a damaged kobra plus (with missing parts) and anycubic is not being helpful.by Dust - General
