Oh yeah, thats it! Thank you very much, it works

Hy, I have an Meanwell PSPA-1000-24 and removed the bridge from the power supply. Then I connected the contacts "Ground" and "PS_on" to the power supply and connect an small 5V power supply (Jumper 5V ext!). If you switch the ATX-Power on (M80) the "PS_on" is connected to the "Ground".

It works fine!

Hello at all,

if I am connect my BL-Touch direct to the Duett WiFi 1.04 like you see at "Connecting a Z probe" he's working very fine on the Expansion "8) Heater 3". And when I connect the Duex to the Duet and the BL-Touch to PWM1 it seems to work too, I can check the settings with the Macros for the BL-Touch - he's working without changing the settings. But if I start the Homing for the Z-Axis the BL-Touch didn't work, no Pin down and I have to stop homing. Can anyone help me please?

Hello Folks,

my Heatbet takes 24 Volt and an resistance (measured) like 17,14 Ohm, this is like 411Watt - 17,14 Amperes. The Fuse on Duet WiFi is like 15 Amperes (Blue). Can I connect direktly to the Duet or did I need an mosfet between the Bed ant the Duet? At this time I connect the Heatbed with an Mosfet, because I don't want to damage my Duet - it works very fine ...

Oh yes, I thank You very much and check it now ...

Thank you for this information!
