@M7460

@deckingman Im using the - 3HC in this case . Would a Pt1000 work better ?

HI Im Trying to connect a thermistor to an IO as i have ran out of temp Sensors .

Can any any one help with the wiring of this as im getting poor readings . 89.4 °C at room temp . it warms up when I put heat to it ...

@deckingman well thats not great.. but thanks for the heads up ! Looks like I need to re-work my panel.

Hi I have an issue with setting a TEMP / Output if they are no on the same board : I get this error

31/05/2023, 19:34:39	Warning: M950: Sensor number 10 has not been defined
31/05/2023, 19:34:39	Warning: M950: Sensor number 11 has not been defined
31/05/2023, 19:34:38	Warning: M950: Sensor number 8 has not been defined
31/05/2023, 19:34:38	Warning: M950: Sensor number 9 has not been defined

I can clear this if I set a heater and a sensor from the same Board. But i can not make this work ... PLease note im using SSRs to enable normal OUTs to be used .

PLease see my Config :

@jay_s_uk

What an ass haha thanks for all your help ! is there anything i can so to add a warning if it not up to temp then exit and stop the macro ?

@jay_s_uk 17c its cold today !

@jay_s_uk awesome ! found my heaters ! So i do not get any error on the console but my IO fires even though I'm not in the correct temp range .

any thoughts?

M42 P8 S0
if {heat.heaters[0].current <193 } && {heat.heaters[1].current <193} && {heat.heaters[2].current <193}
	M42 P8 S1     ; don't forget to indent the following lines to link them to the if-term
	G4 P10000

@jay_s_uk could you please explain a little more ?

Thanks @o_lampe ,

I get the following error :

	Error: Failed to read code from macro Allow Print to start : Failed to evaluate "{m105 P0 S <= 193 } && {m105 P1 S <= 193} && {m105 P2 S <= 193}": unknown value 'm105'

It looks like the m105 is the wrong command to get a reading ....
