This does not document M999 A1 to reset an attached paneldue (which is quite handy). Is that an omission in the documentation, or does it mean it’s a functionality that should not be relied upon?
M140 threw me for a loop. It seemed redundant regarding enabling the bed heater, since the bed heater is defined by M950. Anyway, I had it commented out since it seemed pointless, and drove myself nuts for hours trying to figure out why bed heater temperature wasn’t appearing in the Web interface. I sent a manual command to turn on the bed heater and it said “not enabled”, huh? Out of desperation, I added M140, and presto. My point is that if M140 is not there, you won’t see any bed temperature, even though the M308 and M950 commands are correct.
Thank you for the clarification, and yes, it’s clear that I don’t yet have a firm grasp of the fundamentals. I just put this out there so that others wouldn’t be stuck, not realizing that M140 prevents display of the heater temperature.
All heaters need to be assigned to something. In RRF 2, there were default assignments (and a pain to change if you didn’t use the defaults), but in RRF 3 you need to configure and assign everything. Hot end heaters are assigned by creating a tool. Bed heaters are assigned with M140. Chamber heaters are assigned with M141.

M280 “Almost all servos accept a pulse width range of at least 1us to 2us” should imho be 1ms to 2ms.
