[3.4-b5] Heaters off on start up?

jumpedwithbothfeet

Morning all, I've just noticed my heaters are now off on start up is this the norm on 3.4? I was under the impression the hot end heater starts active as a safety feature, have I missed it in the change logs? I did jump from 3.3 to 3.4b4/5 so more than possible!

dc42

@jumpedwithbothfeet do you really mean heaters, or do you mean fans?

jumpedwithbothfeet

@dc42 I really mean the heaters but mainly the hot end heater always used to start in active but ambient temp and 0 degrees requested so the heater doesn't actually heat now when turning on the printer it is set to off, I repeated this a few times to confirm, my fans work fine, hot end fan starts at 40 and stays on until it drops below.

dc42

@jumpedwithbothfeet if you have a T0 command in config.g (usually at the end) then that tool will be activated and its heaters put in active mode. If you don't have a T command in config.g (or a M568 command to activate heaters deliberately) then no tool heaters should be activated.

@dc42 I do have T0 at the end..

@dc42 Further to the config file, I have been on occasion experiencing the tool board not starting when turning on the printer this is solved by pressing the stop button and it jumps into action but obviously it does connect when the heaters are shown in DWC
