Hotend modes "off", "standby", "active"

bot

I don't know if it's necessarily dangerous to have a tool in standby mode. However, if the standby temperature is set higher than you expect it to be, that could be surprising.

You could set all standby temperatures for all tools to 0, then deselect all tools, via GCode.

thank you for your help

@Plohish Here are the GCode commands you’re looking for:

Tool Status Commands

Standby: 
 	 T-1
 	 or select a tool other than the current tool
	
Off: 
 	 G10 P0 S-273.15 R-273.15

Active: 
 	 T0
 	 or select the tool you wish to be active

Plohish

@mwolter Thanks you!

@mwolter Agreed, thank you. I forgot that you could turn off a heater by setting it to absolute zero.

Plohish

@mwolter can you tell me the same commands for the bed?

mwolter

@Plohish

Bed Status Commands

Standby: 
	M144
	
Off: 
	M140 S-273.15

Active: 
	M140 S110 ; set bed active and to 100c

@mwolter

thank you so much!

mwolter

@Plohish You're welcome. For some reason, this info a little difficult to find. Glad I could help.

Plohish

little problem

comand G10 P0 S-273.15 R-273.15 disables the hot end and sets the temperature = 0 in the web interface, but on the panel the temperature remains the one that was set.
firmware Release 3.0

@Plohish Please update your firmware to 3.1.1 and the Panel to 1.24 and see if that still holds true.

Plohish

@Phaedrux my panel has firmware 1.24
Today I’m not ready to upgrade the Duet to 3.1.1, maybe I will do it later

Phaedrux

@Plohish Its a much easier upgrade than going from 2x to 3x.

Plohish

the ATX OFF button from the web interface turns off the printer even if the hot end has a temperature above 45 degrees, is this normal?

Plohish

@Phaedrux I changed the firmware to 3.1.1
this did not help me solve the problem incorrect display of temperature on the panel

OwenD

Yes it’s normal if you just send M81
Use S1 parameters

M81 ; turn power off immediately
M81 S1 ; turn power off when all thermostatic fans have turned off

Plohish

@OwenD I thought the duet button is much more intelligent and understands that turning off is not desirable
I know about M81 S1 doing it from a macro

Phaedrux

@Plohish said in Hotend modes "off", "standby", "active":

@OwenD I thought the duet button is much more intelligent and understands that turning off is not desirable
I know about M81 S1 doing it from a macro

Perhaps @chrishamm can make that configurable?

Plohish

@Phaedrux What do you think about the problem of displaying temperature on the panel?

Phaedrux

@Plohish I'm not sure about that part either.
