Has anyone performed a BED PID on the new 2.1 firmware? While in Pronterface using the M304 code it does not recognize the code. But M304 works fine when I rolled the firmware back to 1.85.
Any help will be appreciated
joramos10 I'm trying to run Auto PID for the bed and after entering: M303 E-1 S70 C10 I get the error: PID Autotune failed! Bad extruder number I'm running the latest version of TH3D Unified Firmware ver U1.R2.1d on an Ender 3 with EZABL. Auto PID for hot end works without a problem. Had the same problem under ver U1.R2.1b
It is not enabled for printers with the 1284p chips due to memory constraints. Its also not needed for a bed.
