SKR 2 Marlin 2.0 Configuration help for Ender 3 Pro
August 25, 2021 03:35AM
I am another one of those 3D printer users that have been searching hours online for help with the SKR 2. It's amazing how little information there is for this board.

My Setup:
Ender 3 Pro v1 with OEM display
OEM Hotend and Extruder - Not Direct Drive
SKR 2 Rev B
BLTouch v2 with Hero Me gen 5 Cooling fan Single 5015
TMC2209 Drivers
No Linear Rails

I was using the Marlin example files Located under the Ender 3 Pro folder for Creality V4.2.7 and comparing it to BigTreeTech SKR V1.4 Turbo.

Can someone with more knowledge and experience take a look at my attached configuration files, Please let me know if I have everything set correctly. I really want to make sure I will not fry my board or drivers.

The area that I'm least sure about is around the TMC2209 drivers, making sure everything is set correctly. I have a BLTouch and do not wish to use sensorless homing.

In Configuration_adv.h, there are two lines specifically:

The BTT version shows:

Line # 2586
#define X_CURRENT_HOME (X_CURRENT/2) // (mA) RMS current for sensorless homing

and

Line 2604
#define Y_CURRENT_HOME (Y_CURRENT/2)


The Creality Version shows:

Line # 2586
#define X_CURRENT_HOME X_CURRENT // (mA) RMS current for sensorless homing

and

Line 2604
#define Y_CURRENT_HOME Y_CURRENT


Which is correct or does it matter? Anything else I need to change or configure?

Homing current is normally halved, so it doesn't bash the end-stops or end of travel to violently, but if using sensorless homing you may need full current to bash into the ends it for it to register correctly.

This is a machine setting and has little to do with the type of controller.

The board is well documented here [github.com]

... homing current too? - my CNC-controllers reduce only the homing speed ...
