Anything related to printer controllers not being Duet, RAMPS or Sanguinololu: microprocessors, motor and heater driver circuitry, gEDA/KiCAD issues, soldering tips, etc.
Keeping up with 2.0.x.x changes-need more details - 6 years ago
There are a large number of bug fixes, changes, and new features in stream of Marlin 2.0.x.x email updates but the comments are so brief like: New Controller Fan options and M710 G-code. Add M42 M to set pin mode. Are there docs that describe the features and fixes in more detail or do I need to scour the source code comments?by Dr Oldies - Firmware - Marlin

Yes, I missed the obvious here. I will add the resistor+capacitor pair as in the attached schematic clipping you referenced, and try again. Thanksby Dr Oldies - Controllers
Re-ARM+RAMPS+Marlin sensor analog input pins - 6 years ago
I'm setting up my 3D printer for 4 nozzle, 4 stepper color print. My setup is Re-ARM+RAMPS 1.5+Marlin 2.0 (debug) in EEB configuration with two additional stepper motors using a motor extender card. T0, T1, T2 (A0-A2) analog inputs as heater temperature sensors work fine. However, none of the other pins labelled as analog input capable work. I've disable the LCD for the pins on that pin clusterby Dr Oldies - Controllers
