@bartekp have you solderd the wires to the bed directly??????

[bartekp]

@pcr I thing yes I connected one to the ground and seccond to the hbed fuse

[bartekp]

@bartekp its looking up the mosfet is death what to do ?
can I avoid hotbed mosfet ad connect signal to the ssr for heat bed?

[jay_s_uk]

@bartekp use a fan output for the SSR if you have a spare one

[bartekp]

@jay_s_uk ok how to use should I made some code to config g?

[jay_s_uk]

@bartekp

M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0

to

M950 H0 C"fan2" T0 ; create bed heater output on bedheat and map it to sensor 0

or, as you're using fan2, use e1heat

M950 H0 C"e1heat" T0 ; create bed heater output on bedheat and map it to sensor 0

[bartekp]

@jay_s_uk I have one normally open fan add two controlable

[bartekp]

@bartekp this fans I have free , wich i should connect to ssr?

[jay_s_uk]

@bartekp B or C.

You'll have to comment out the corresponding line in your config.g though as you currently have fan1 and fan2 assigned to fans

[bartekp]

@jay_s_uk Works fine Thanks problem solved
