Summary

Yet another temperature calibration tower. It suppose to be smart, compact and fulfill several purposes.

it is functioning as a regular temperature tower
it contains several test patterns like
- overhangs from 60 deg to 25 deg
- bridges from 15 mm - 30 mm
- stringing test
- curvy shapes

One floor is exactly 10 mm and stand is 1.4 mm. Optimized for 0.2 mm layer height.

Note: STEP models have been added of a plain floor, 000 Floor and the stand.

Updates:

21-Dec-2021 - Added link to tutorial videos
10-Jun-2019 - Added single line script
19-Apr-2019 - Added scrips for PETG and PLA_Plus and a screen shot of the script setup

Notes:

Correct temperatures have to be setup in the generated gcode.
It can be easily done in Slicr3d Prusa edition min. v 1.38.5. linked version 1.41.3 still work just fine

Printer Settings -> Custom G-code -> Before layer change G-code
correct macro needs to be setup. It should look like one of two options

1. If statement based script

{if layer_z==1.6}; T tower floor 1
M104 S250
{elsif layer_z==11.6} ...

It specifies different temperature for each temperature tower floor. You need as many elseif-s as many floors your tower has got.

There are 4 pre-created txt files included in the project with the macro of

ABS_t_tower_before_layer_change_macro.txt
PLA_t_tower_before_layer_change_macro.txt
PLAPlus_t_tower_before_layer_change_macro.txt
PETG_t_tower_before_layer_change_macro.txt

2. layer_num based script

It is an simpler way to achieve the same for 0.2mm layer height. It is just a single line of code you need to copy/paste and change the START_TEMP to the correct value:

M104 S{<START_TEMP> - (layer_num-7) / 50 * 5} {if layer_num > 7} ;T tower floor {(layer_num-7) / 50 * 5 + 1}{endif}

where START_TEMP is the temperature of the first floor. Example of a PETG script:

M104 S{265 - (layer_num-7) / 50 * 5} {if layer_num > 7} ;T tower floor {(layer_num-7) / 50 * 5 + 1}{endif}

It adds temperature change gcode to each layer unlike the verrsion with if statements It adds temp change gcode on at the first layer of a floor.

Content can be easily copy/pasted.
See the attached screenshot

How to use it?

There is 4 complete temperature towers

PLA 180C - 225C
PLA Plus 195C - 235C
ABS 200C - 250C
PETG 220C - 265C

These can be used as they are. Don't forget to setup correct temperatures. See the section above.

There are also separated modules for temp floors from 170C to 265C with 5C step and a stand. New heat tower can be easily combined out of them.

Why another new temperature tower?

I started with 3d printing by may of 2017. I wanted to learn as much as possible in the shortest possible time and speed up configuration of my printer as much as possible. Print out long lasting temperature towers and then other testing shapes was too long to me. So I decided to create a new heat tower which is as compact as possible, serves many basic quality test purposes too and printing take as short time as possible.

I am using it as a basic temperature setup guidance for different filaments. It sped up my setups at least 3 - 4 times. One print instead of 3 - 5.

Currently I am bringing it to you. Enjoy it and I am looking forward to reading any feedback.

OrcaSlicer picked this design as base for auto generated temp tower. BTW it would be nice to see there at least a mention about that somewhere in the list of credits ;-)
