Creating a Temperature Tower

creating a temperature tower

I have used enough filaments to feel the need to have a semi automatic way of finding out the good temperature for a print. One that reduces stringing, does not induce warping and gives a nice looking print.

I decided to follow the instructions in here

I don’t have anything fancy in mind, so I’ll try the first suggested tower.

  • Temp Tower #1 by stoempie:
  • https://www.thingiverse.com/thing:2493504
  • 0.2 layer height.
  • 95% infill.
  • Base is 4 layers.
  • There are 34 layers in each test block.
  • Layer numbers needed for scripts 1, 38, 72, 106, 140, 174, 208, 242, 276.

So far, the filaments I have been using appear to have been working at relatively low temperatures, so I guess I might like this file.

But, I might need to take a look at this one for some particular filaments.

Fortunately, I don’t have to click on the script button again and again. I can simply save the project, unzip the file and edit the post_processing_scripts to ressemble this

Then, I zip it and load it in cura.

I get all the post_processing_scripts parts without much effort

The 3mf file I get is this one https://konubinix.eu/ipfs/QmcfVgRH9DtyXRHzqGK6XETrk4gPF9fJaF7fqepMGMPRpc?filename=210.3mf

210.gcode

After printing it with all the filaments I have.

I realize that they are all not doing great, but I assume it is was I can expect from the labists x1 mini. It gives me a good idea of the temperature to use though. Actually, the correct temperature to avoid the stringing appears to be lower than the given one. Maybe I should play a bit and increase the retractation factor.
