Temp change in slicer
I'm trying to print a temp tower but the temp does not change. Is there somewhere in the slicer to set temp by layer? I am using Prusaslicer and a Core One+. Is there another way? TIA
RE:
You usually need a dedicated custom gcode per layer, or just find models on printables that already have that prepared as 3mf file for your specific printer model.
See my GitHub and printables.com for some 3d stuff that you may like.
RE: Temp change in slicer
It's been a while so I don't know if the state of art has changed, but I loaded in one of my temperature towers and you can see from this screenshot how I inserted custom gcode where I wanted temperature changes to happen. I started with the high end of my tested temperature range on the bottom of the tower, going to cooler temperatures on the way up. That way if I got to a temperature that was too cold to print reliably (happened a couple times with some more extreme towers) the fail happened after the good print. (Click on image to get the full size)
As I recall, I intentionally used the M104 gcode so the print wouldn't be paused waiting for the temperature to change. In practice the cold filament entering the melt chamber while printing usually cooled the extruder by the target 5°C delta by the time the first layer after the M104 finished printing.
For reference, the temperature tower models that I use I originally got from Thingiverse, I haven't looked to see if they were mirrored anywhere else (though I notice that the temperature tower in OrcaSlicer is supiciously similar without attribution that I've noticed). It includes a couple completed towers and the individual temperature-labeled blocks to build one's own tower in the slicer (which I've done a few times). Here's the repository: https://www.thingiverse.com/thing:2729076
I think this repository was written before slic3r-PE had the capability to add custom g-codes at specific layers because the description shows a couple techniques for using custom gcode in the printer profile. (These techniques should also work in the current generation of PrusaSlicer if you don't like adding custom gcode in the slice preview.)

RE: Temp change in slicer
I wrote some code (well the AI did mostly) to parametrically generate a temperature tower and upload to the printer: https://forum.prusa3d.com/forum/english-forum-general-discussion-announcements-and-releases/filament-calibrator-standalone-gui-for-calibrating-3d-printer-filaments/#post-784955
Can give this a try. I use it for my own stuff (being that I wrote it).
