I was trying to configure Marlin ( as per Chris Warkocki, https://www.youtube.com/watch?v=EWjKpgYp5wQ) for a PRUSA i3 MK3s BEAR Upgrade. After modifying Configure.h and Configure_adv.h, Marlin wouldn't compile. I traced down the following #defines as the issue:
#define LCD_INFO_SCREEN_STYLE 1
#define FAN_MIN_PWM 80
#define NUM_Z_STEPPER_DRIVERS 2
There are others, but these appear to be the Main issues. I have a bunch of questions, but if we can figure out these issues, I'll follow up with more.
