I've switched to a PLA of a different color and wanted to figure out what temperature my nozzle should be so I printed a temperature tower. However, the towers came out perfect and the only stringing was from the last bit of plastic oozing out when the print head moved to X-home.

I loaded the tower stl file in Ultimaker Cura and did the post processing script to change the temperature from 240 °C at layer 1 (changing from 200 for the skirt). And decreasing the temp by 10 degrees every segment after. Here is the resulting print vs the expected print: Actual Temperature TowerExpected Temperature Tower

I was expecting an over-extruded, blobby mess and stringing to make a spider feel at home towards the bottom, but this is one of my best prints yet.

I watched the print in its entirety and the printer was set to the respective temperatures and the nozzle reached them, as confirmed by OctoPrint: OctoPrint Temp Graph

And the G-Code does have post processing scripts generated by Ultimaker Cura: G-Code

Any ideas why my print looks so good? I'm printing PLA at various nozzle temps, 60 °C on bed with the Creality CR-10S sliced with Ulitmaker Cura 3.6.0.

  • $\begingroup$ Not in this particular model. However uploaded images of the print show that globbing doesn't necessitate the bridges. I'll see if I find an image. $\endgroup$ – Lux Claridge Jan 22 at 14:46

    $\begingroup$ Your material works well at a larger temperature range than expected. What was the problem? $\endgroup$ – Davo Jan 22 at 14:51
  • $\begingroup$ I'm under the impression that 220 °C is extremely high for PLA let alone 240 °C. Have a hit the lottery with this filament then? $\endgroup$ – Lux Claridge Jan 22 at 14:54
