Hello, thank you for sharing your firmware with the community, but I need help. It turns out I want to use the firmware for the Ender 3 + the SKR Mini E3 V2 board + BLTouch, but it’s not suitable for my Ender 3 Neo printer. The main issue is that it prints off the bed, since the minimum positions on the Ender 3 Neo are in the negative. Additionally, if possible, I’d like to modify the factory extruder steps from the start, where I changed it to 424.9.
Thank you so much for your work—you’ve saved me from having a useless printer
I use Pronterface, a small utility that connects to your printer via USB and allow you to query firmware settings of your pinter as well as change settings.
I think your off bed issue may be corrected with an M206 offset command and your E-steps can be changed with an M92 command.
These are G-code commands and you can find the entire list and definitions by googling Marlin GCODE.
