Heater Control
-
Ok, I plugged the parameters into M307:
M307 H1 A884.2 C296.0 D6.8 B0 S0.8I did leave S0.8 for no good reason. It is working perfectly - climbs steadily up to my target (190°C) and then levels with no overshooting and stabilizes much faster with less than +/-.1°C variation. Much better than what I had before.

Thanks David.
But this begs the question - what's the "right" thing to do from a heater perspective? Is this legitimately a safety concern and if so, what should be done to rectify it? Is this unique to my E3D V6 or all of them?
You might want to consider replacing your 40W heater cartridge by a 25W one, which I understand is what E3D ships as standard these days. Otherwise you might suffer a heater block meltdown if the heater ever got stuck at full power.

30w is now standard, which tops out at ~330C without heater block insulation or a fan blowing on the heater block.
40w will get hot enough to melt the aluminum in the event of a firmware/FET failure.

Ok, this is good to know! I will check and update the cartridges in all of my printers. No need playing with fire!
