Benchmark Bot

Move over boat, there is a new benchmark in town.

This robot is not only a fun print-in-place figure but it is also a very useful calibration tool.

The robot is designed with 17 functional joints with different orientations, couplings, and tolerances. The tolerances range from 0.2 - 0.5mm and allow you to test the minimum clearances your printer can produce and still achieve print-in-place movement.

Each limb is labeled with the tolerances of their joints and all other joints have a 0.3mm tolerance. It might take a little (just a little) bit of force to break them free any more and you risk breaking the robot.

It only uses 20g of filament and is small enough to fit on a Prusa mini or even a Voron V0.

Clogged nozzles, layer shifts, poor layer adhesion… anyone familiar with 3D printing will recognize these!

Are getting or giving a 3D printer this holiday season? This model is the perfect first print! Just hit print and walk away. Any flaws will only make it better!

3D designing and printing teaches us to expect mistakes, plan for them, fix them and try again. If you are new to 3D printing, you can expect to have more than a few prints that come out looking something like this mug.

Disclaimer: All flaws in this model are intended and don’t represent the quality of the brands shown! Lulzbot makes excellent printers and eSun makes excellent filament. Both are great options for avoiding the 3D printing pitfalls that you see in this print!

My own version of the popular model used to test out printing tolerances, surface quality and to tune up your slicing profiles for every filament change.

This 20mm calibration cube has almost everything you need to check before actually start your prints: overhangs, bridging, retraction, ghosting, stringing, etc.

You can enjoy making it and have an actual cool, original and good-looking cube!

Happy printing everyone! 🎲

Lattice Benchy (Wicker Lattice)

The hull and walls of this Benchy are built with face-centered cubic lattice structure. Great to show off your resin printer, but not very seaworthy.

Perfect First Layer Test

This is a first layer calibration test for any printer. It consists of 5 tiles 32 mm wide.
 
---

**Recommended print settings**

- layer height: 0.2 mm
- fill angle: 0°
- perimeters: 2
- first layer speed: 25 mm/s

It should be centered on the bed and stretched as close to the edges as possible (exactly like this in the right picture).

Live adjust Z while printing, if necessary.

---

**Interpreting results**

Each square should look the same. Surface of the prints should be smooth and pleasant to the touch (just like the one in the left picture).

The tiles should be very difficult to tear apart.

XYZ Calibration Test - Vase Mode

Quick 10 minute print - 0.3 m of filament

Don't waste your precious time and filament printing a so called “calibration cube”!

This quick print provides clues for all the important features and settings:

Extrusion width
E-steps / rotation distance (X, Y, Z)
Bridging
Cooling
Overhangs
Speed / accelleration
First layer / bed adhesion
Retraction (stringing test, seam test)
Preassure advance / linear advance
Print Settings
1 perimeter
0.2 mm layer hight
3 bottom layers
Disable “Ensure vertical shell thickness” (PrusaSlicer)
No Infill, top layers, brim or supports

**Troubleshooting**
https://www.reddit.com/r/3Dprinting/wiki/troubleshootingandcalibration

Some quick tipps:

_**Extrusion width**_
Check if the thickness of one of the outside walls at the top matches the setting in your silcer
**_E-steps / rotation distance (X, Y, Z)_**
If the outside dimensions are not 20 mm but way off, correct the settings for the affected axis
**_Bridging / cooling_**
If the bridging perimeters in the top center are drooping/sagging, check cooling an bridging settings in your slicer
45° overhangs
If the perimeters in this section are drooping/sagging, check the part cooling and cooling settings in your slicer
**_Speed / accelleration_**
ringing, bulged corners - you may want to reduce speed and/or accelleration (also see Preassure advance / linear advance)
**_First layer / bed adhesion_**
If there are problems with the print adhering to the bed, check if
- the bed is level and parallel to the x-axis
- the bed is clean - no dirt or grease
- the bed temperature is correct
If the print is wider at the bottom (first few layers) than at the top, check your z-offset and first layer settings
**_Retraction (stringing test)_**
If you experience stringing, check your retraction and cooling settings
**_Preassure advance / linear advance_**
If large seam gaps or bulged corners appear, consider tuning your printer firmware settings for preassure advance (Marlin) / linear advance (Klipper)

XYZ Calibration Test

XYZ_CallibrationCube.stl

This is a small and simple XYZ calibration cube for checking the dimensional accuracy of your printer.   The cube has X, Y and Z written along their respective axes.

Once printed either use an accurate ruler or callipers to measure the dimensions of the print. The original model size is 20mm*20mm*20mm however you may wish to resize it to be bigger (or smaller). 

Once you have measured your dimensions you may want to adjust the steps or steps per mm for each axis in your printers firmware - This may or may not be possible depending on your printer. 

To do this you will need to find your current Steps per mm, and then have your observed dimension and expected dimension.

To calculate the new Steps per mm you will need to do:

(Expected/Observed)*Current Steps per mm = New Steps per mm

It is also good as just giving a gauge of how well your 3D printer works with small over hangs and flat faces to check for Z-Banding or ghosting!

Lost Factory Cube - A generalist *diagnostic* cube

This cube tests for a lot of basic calibration and hardware issues on an FDM printer, all at once.

You need to print this cube:- 

at 0.2mm layer height
on a 0.4mm nozzle (or smaller) with 0.4-0.46 line width
The screw and rod parts snap off to test in the screw holes and normal holes. There are ghosting, overhang, cooling, ovality tests among other things.
