Temperature ladder

Post by bbc0 » Sun Aug 25, 2019 2:29 pm

Folk have advised me to print a temperature ladder with new filament to determine the best hot-end temperature to use with it. Is there a way to automate this so that the temperature set point is adjusted automatically at each step?

I'm assuming the temperature ladder is an .stl file that is sliced to produce .gcode. The .stl file can be procedurally generated but none of the existing slicers that I am aware of have a way of dynamically changing the hotend temperature (unless it supports post-processing extensions). G-code doesn't have any support for doing math. The best you could do would be to post process the .gcode file with slicer extensions or a program of some sort.

OK thanks for the response.
So without be able to adjust the set point for each temperature step, what would the procedure be for printing a temperature ladder on my original Mini?

Pick a temperature tower model. The model should have instructions that describe its geometry including a recommended layer height. Using these parameters in your slicer and produce a .gcode file. Edit this .gcode file inserting "M104 Sxxx" commands at the appropriate locations (by layer or by height).

Here's a pointer to one that includes everything you should need including post processing macros, https://www.thingiverse.com/thing:2729076. If you don't like that one, here's a pointer to everything tagged with "Temperature Tower", https://www.thingiverse.com/tag:Temperature_Tower

Google will be your friend if you ask it the right question. Try "automated 3d temperature tower" and throw in the name of your preferred slicer.
