Feature Request: Temperature change on Filament Change and/or Layer Height

[MrTantrum]

On my MK3S+ I print mostly multi-colored models (non-MMU) with one or more filament changes during the print. While I always use the same filament type in my prints (e.g. all PLA), I do utilize different filament brands and colors. Often times, these filaments have ideal print temperatures that may vary as much as 30 degrees.

Currently, I have to remember to manually change the print head temperature manually upon filament change, but it would be nice if there was a feature built into Prusa Slicer where the print head temp could be set in accordance with a filament change (preferred) and/or the temp could be set at a given layer height.

Duplicate of #2002, #2255, #3439, #3439.

As a workaround, you can add M104 Sxxx (xxx = desired temperature) custom command using vertical slider, so it will change the temperature automatically at the specified layer.

I am closing this as a duplicate.

Use code in the Before/After layer change G-code

{if layer_z==10}M104 S{first_layer_temperature[0]+10}
{elsif layer_z==20}M104 S{first_layer_temperature[0]+20}
{elsif layer_z==30}M104 S{first_layer_temperature[0]+30}
{elsif layer_z==40}M104 S{first_layer_temperature[0]+40}
{elsif layer_z==50}M104 S{first_layer_temperature[0]+50}
{endif}

Thank you for your response. I understand how to inject G-code manually, but this is performed on such a frequent basis that it is quite inconvenient. Would be extremely helpful if such a feature was embedded into the Prusa Slicer GUI somehow.

Actually, I just saw your comment about inserting the G-Code via the vertical slider. I wasn't aware of this feature and serves as a valid and practical way to achieve what I'm requesting. Thank you.

Upon testing this method, I was unable to add both a color change and custom G-code at the same layer height. I assume the workaround would be to inject the temp change at either the layer immediately before or after the color change?

[rtyr]

Either that, or you can only add custom gcode like this (2 lines - M600 command is for color change)

M600
M104 Sxxx

Thank you for the suggestion.
