Questions on Startup Script

BlueDust

I am trying to create one script to enable and heat up my bed and hotend, but having trouble understanding the best way to do it.
I used to have a few scripts, and while looking into each Gcode command it seems at least one has been deprecated, and possibly why I am having trouble.

How do I choose to enable Standby or Active for each, the hotend and bed. It seems I was able to control this for the Hotend at one point, but when I figured out how to make it Active, I do not know what I did to make it standby. It may have worked when I used the deprecated command (M104)... I have only been able to get the bed to work in Active mode, and not Standby.

M140 R60 S75 		;Bed Temp
T0		        ;Enable Hotend - Active.
G10 P0 R200 S245	;Hotend Temp
M116 			;Wait for heater teamps

G28
G32
G29
G0 X125 Y0 Z25 F6000

What is the difference between Standby and Active? Only the Temp setting differences? Do they have a use case? Possibly only when having multiple extruders?

Thanks!

only when having multiple extruders

Correct.

And G10 is a good CONFIGURATION command for setting Hot end Active and Standby temps, so that they will happen automatically as you switch tools. As you said, ONLY useful on a Multi-Extruder printer.

To simply set the current tool, and/or wait on it, use M104 (to set, no wait) M109 (to set and wait). Also, for the bed, consider M190 to wait. This helps prevent cooking the hotend with a bed that takes a while. The temp section of my typical G-Code job startup:

T0
M190 S60
M104 S210
M109 S210
