i only use Tool 0 first nozzle - and the seoncd is hardly used - multi colour or disovable supports so i only monitor tool 1 first hotend when it reaches 45deg to turn on

@phaedrux

Hi

I've upgraded to 3.4.1 however my heatbreak fan will now run at full speed and i can't lower the speed.

M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
M106 P1 S0.5 H1 T45 ; Set Heatsink fan Port 1. Thermostatic control is turned on

i've tried using S127 to see if this would change the speeds and no
i've tried using the slider in DWC but nothing happens either same as sending

M106 P1 S0.3 with different S variables while the machine is idling at temperature and nothing happens

Thank you

@baird1fa no all my fans are 24v - no converters in place

Hi guys

I have an issue with my setup but dont know whats causing it.

I have wired up some stepper cooler fans to the Always On port of my board, however since doing this when i turn on my machine my heatsink fan now starts up ( ignores the 45deg temp setting to turn on ) and my parts cooling fan turns on slowly as well.
if i disconnect the always on fan everything operates as normal but plug the fans back in they all spin on startup

do i need to enter something into my config to stop this from happening?
i current have this set in my config.

Thank you

I still had the same issue,

Then i realized while i'm playing with my machine i have a macro that calls M564 S0 H0 so i can move my machine around without being homed for testing as this is a fresh build i'm ironing out the bugs.

so therefore when i use that marco it never resets when you do a call home thus the X axis is always crashing as the machine doesn't know it's position.
to safeguard myself i've put M564 S1 H1 in the start of my homeall file

Thanks for your assistance

Thanks for the tips guys - didn't know that about Homing a coreXY - if i read the Wiki properly i would have i copied my config from my Cartesian and it's caught me out!

I will see how it goes

Thank you
